A Geothermal Heat Pump (GHP) is a device that extracts heat from beneath the ground. It functions based on the fact that heat will flow from higher temperature materials to lower temperature materials by conduction or by convection (air currents). Geothermal pumps absorb energy from the ground or bodies of water to provide space and water heating. This works because the earth absorbs about 50% of the sun's energy that reaches the surface of the planet.
Ground source heating and cooling provides high-comfort and cost-effectiveness with an environmentally friendly technology that makes use of the Earth's capacity to store energy in the form of heat. Geothermal Heating Systems move heat from the earth or water into a building, or from a building back into the earth. A small amount of electricity is used to operate pumps, fans, controls, and small compressor.

Geothermal heat pumps (GHPs) are among the most efficient and comfortable heating and cooling technologies currently available for homes and other buildings. These ground-source heat pumps use the natural heat storage capacity of the earth or ground water to provide energy efficient heating and cooling. Most GHPs are installed with "Desuperheaters" which collect waste heat from the compressor and use it to pre-heat domestic hot water for free. This is a new money-saving technology for homes.

Although the initial cost of a new geothermal system is generally more expensive than a traditional heating and cooling system, the extra investment is returned within five to ten years. The ground loop piping is estimated to last over fifty years, and even the internal parts have about a 25 year life span. Every year about 50,000 new geothermal heating systems are added in the United States. They're very reasonable for most areas and can use the Earth for heating when temperatures drop and as a heat sink when it's hot outside.

Many new residential systems are equipped with desuperheaters which transfer excess heat from the geothermal heat pump's compressor to the home's hot water storage tank providing very efficient water heating. However, the desuperheater will not provide hot water during the spring and fall when the geothermal heat pump system is not operating. But because the geothermal heating system is so much more efficient than other means of water heating, some manufacturers are offering 'full demand' systems that utilize a separate heat exchanger to cost-effectively provide for hot water needs.

Geothermal Heat Pumps are among the most efficient and comfortable heating and cooling technologies currently available for homes and other buildings. These Geothermal Heating Systems use the natural heat storage capacity of the earth or ground water to provide energy efficient heating and cooling.

Geothermal energy is one of the renewable forms of energy being utilized today in various applications. As a natural resource that is in abundant supply, its usage in the future is expected to grow more.

The term geothermal is actually a combination of two Greek words – geo which means earth and therme meaning heat. As one of earth’s resources, geothermal energy is clean and can be sustained for long years.

This alternative energy comes from the earth’s heat found underneath its surface. The earth’s crust is mainly a result of the past existence of millions of volcanoes and great volumes of magma that did not erupt but rather cooled below the surface. In addition, the earth’s core has high temperatures between 50 and 60 degrees Fahrenheit that remain constant throughout the year.
This makes it an ideal source of heat for various purposes. Among its resources include the shallow ground, hot water and hot rock below the earth’s surface and molten rock or magma deep down. These resources have two main categories – the high temperature (220 degrees Celsius and above) geothermal resources found in volcanic regions and island chains and the moderate/low temperature found on all continents. The high temperature resources are mostly used in power production.

Technologies

In extracting hot water for geothermal reservoirs, wells are normally drilled into underground reservoirs for use in generating electricity. The steam from a reservoir is used by some geothermal power plants to power turbine/generator. Other plants use the hot water to boil a working fluid that vaporizes and then turns a turbine.

Hot dry rock, on the other hand, can be found about three to five miles deep down the earth’s surface. In certain areas, they can be found at lesser depths. To extract heat from these rocks, cold water is injected down a well which filters through the cracks in the rocks situated in the hot region. Heated water is eventually drawn off from the recovery well. This then flashes into steam upon reaching the surface.

Steam can be used to drive a turbo generator. However, in order to do this, steam must first be purified. In heating homes, it can pass through a heat exchanger to provide heated water.
A hot dry rock system (EGS) reaches at least 10 kilometers down into hard rock. It is estimated that the United States alone has a huge resource of hard rocks that can supply the world’s energy needs for some 30,000 years.

Major uses

Hot water sourced underground can be used in a number of ways such as in generating electricity, heating buildings, growing plants in greenhouses, drying crops, heating water at fish farms. In industrial application, it is used in pasteurizing milk.

Geothermal heat pumps are used in heating and cooling homes and buildings. This type of heating system is made up of a heat pump, ductwork or air delivery system and a loop or a series of pipes buried in the shallow ground near the home or building.

Currently, geothermal power is produced in more than 20 countries. These include the U.S., Italy, Germany, France, The Netherlands, Mexico, Russia, New Zealand, Turkey, China, Japan, the Philippines and Iceland. The first geothermal power plant was constructed at Landrello, Italy while the second was built at Wairekei in New Zealand.

It is important to learn more about different types of alternative energy sources like geothermal energy.

Choosing the right baby nappies for your new baby can be quite a daunting task. There are so many different types, brands, sizes and shapes on the market.

The cheapest disposable nappies often contain harsh chemicals such as absorbent gels and bleaching agents. These chemicals cause damage to your baby’s skin and to the environment. It may shock you to hear that up to 8 million nappies are thrown away every day in the UK, and that 90% of these end up in landfill, where they can take up to 500 years to biodegrade!

Real nappies can be more expensive to buy, and are more time consuming to wash, but they could save you a staggering £500 (compared with disposables). Also, due to the UK waste management problem, some local authorities offer mothers incentives to choose real nappies over disposables. For instance, Denbighshire County Council offer mothers real nappy vouchers worth up to £75.

But what if you want the convenience of a disposable, without feeling guilty?

Spirit of Nature offers a wide range of affordable baby nappies which are kind to the environment and to baby’s skin. They offer real nappies, semi-disposables and ECO-disposables, as well as biodegradable sacks & liners.

Bambo Nature and Moltex Eco nappies are a fantastic alternative to conventional disposables. They have the same great features as standard disposables, but are made from natural fibers, free from harmful chemicals, and come at an affordable price! ECO-disposable nappies biodegrade in as little as 6 months when put in a worming compost and they take significantly less time to biodegrade in a landfill site.

Spirit of Nature also offers the very best of both worlds! Weenees nappies are natural, reusable nappies which contain disposable and biodegradable nappy liners. This is THE Eco Friendly Compromise to the debate!

When you are choosing baby nappies for your new baby, make sure that they are kind to your baby’s skin and to the environment!

Wood pellets have become the standard source of fuel for many homes across the world. Countries like Sweden pioneered the usage of this carbon-neutral fuel while now it is a rage in homes in the UK as well as US. There are several criteria and norms of quality that get followed while assessing the relative quality of the pellets.

DIN 51731

This is essentially a European standard of establishing the overall quality of wood pellets. While on the whole this is a holistic method of identifying the condition of the pellets it fails to take into account an essential factor like abrasion. In addition to this it also does not include any assessment of the process of manufacture to be done. Thus in essence the standard is lacking because of the absence of certain parameters.

Norm M 7135

This is traditionally originated from Austria. There are far more criteria included in this method of assessing the wood pellets. Factors like abrasion which are absent in the DIN 51731 are included in the Norm M 7135. The overall stability as well as hardness quotient of the pellets is ascertained before it is given this quality check. Using a Lignotester the wood pellets are stressed in order to ascertain their abrasiveness. The dust that is an outcome of this exercise is then evaluated for abrasion standards. If there is a lesser fraction of dust obtained it indicates a much more solid set of wood pellets which in turn yields a lower abrasion count.

How inspection is carried out

The institute of DINPlus is responsible for certifying and assessing the norms of quality in the wood pellets. The certification process is carried out by the certification members who strictly follow all the standards as laid down by the DIN Certco. There are several controls which get placed to secure high quality of the wood pellets. One additional guarantee seal is provided by the PVD or the Pellet Association Germany and the seal is called the GGuaranty seal. This seal has the same stringent set of criteria as recommended by DINPlus.

What criteria are ascertained?

There are many criteria associated with the wood pellets which are assessed before a seal of approval is provided. Aspects like the diameter of the pellets, the length, density, heating value, humidity, sulphur, chlorine, ash, nitrogen content as well as the levels of abrasion and press aid all are taken into account before assessment begins. It is to be noted that all quality checks are considered only till the point when the wood pellets are loaded. After that these aspects are not taken into account.

ONorm 7136

This is another norm which takes into account the quality of wood pellets during and after transportation. For example the pellets can actually go through plenty of wear and tear during the process of transportation. Therefore this standard emphasizes the quality of the bunker, supplier, as well as transportation vehicle too. Aspects like scales on board, quality of suction mechanisms as well as insulation from humidity levels are all calibrated. Thus this norm aims to establish a superior quality level during the transportation of wood pellets.

The whole purpose of skincare products is for the lotions and potions to be absorbed by your skin. Simply put, if you're putting it on, it's going in. And that means your body will be soaking up all the ingredients in your skincare products - whether they are synthetic or natural.

It may shock you to learn that there are many chemical ingredients in skin care products that are banned from being taken orally, but given the green light for inclusion in skin preparations. These toxic chemicals are absorbed into the blood stream through your skin and some doctors believe they are the source of eczema, asthma and even cancer.

But not all chemicals are bad. Unless you are willing to keep your skincare products in the fridge, they need some chemicals in them to preserve them and give them a shelf life. What you need to do is to find skin care products that ideally omit or use the lowest concentration of potentially harmful chemicals.

The list of chemicals used by skincare manufacturers is extremely lengthy. Pick up any product on your bathroom shelf and you are likely to be baffled by the long, complicated names of ingredients. However it is possible to highlight a few ingredients that may be worthwhile avoiding, as they are recognised as the possible cause of health problems.

1. Parabens (methyl, propyl, butyl etc): Widely used as preservatives, Parabens have been linked to hormone function imbalance and have been detected in breast tumours. They have also been linked to asthma and eczema.

2. PEGs: Otherwise known as Polyethylene glycol (PEG) is used in cleaners and even some oven cleaners to dissolve oil and grease. They may also be contaminated with Dioxane, a carcinogen. PEGs are found in many personal care products.

3. Phthalates: These are found in so many products, from plastics to shampoo. They are believed to be hormone disrupting and can cause damage to vital organs. Diethyl phthalate (DEP) is found in fragrances but it has been linked to infertility and birth defects. Unfortunately manufacturers are not required to list phthalates on labels, so they are difficult to avoid.

4. Sodium Lauryl Sulfate: SLS is used in thousands of cosmetic and health care products, including most toothpastes. It is used to create lather. It's a strong degreaser that dries skin and hair and can cause eczema in some people. It took me twenty years to realise that it was the SLS in my toothpaste that was causing my miserable battle with mouth ulcers.

5. Propylene Glycol: This is recognised as a neurotoxin and is known to cause dermatitis, kidney damage and liver abnormalities. Even so it is widely used as a moisture-carrying ingredient (humectant) instead of glycerine because it is cheaper and absorbs well. It is used in antifreeze and hydraulic brake fluid and some manufacturers use it just to keep their machinery well oiled - it has no function in the product itself!

6. Diethanolamine (DEA), Triethanolamine (TEA) and Monoethanolamine (MEA): These are known to be hormone disrupters and can combine with nitrates to cause cancer. Unfortunately these ingredients do not need to be listed on product labels.

7. Synthetic Fragrance: This is a term used by manufacturers to hide a plethora of ingredients, many of which you may wish to avoid.

8. Alcohol: (Isopropyl Alcohol, SD Alcohol 40, Ethyl Alcohol): Alcohol is drying; it dissolves the body's natural moisture and strips the skin of its natural protection. Although it has been used traditionally to help spot-sufferers, in fact it simply encourages the skin to produce more oil, exacerbating the problem. Alcohol can destroy the skin's natural pH balance and even speed up wrinkling.

It is not often realized that the materials used for interior design could be threatening the environment or even your health. It is always a wise option to look out for an eco-friendly interior designer who could bring your ideas to your life at an affordable cost while ensuring the materials used don't endanger the environment or put you at the risk of respiratory problems and other conditions.

Paint

A host of eco-friendly solutions are in the market if you only look for them. Eco-friendly paint is one, conventional paints and finishes are quite dangerous if scientific reports and investigations by interior designers are to be believed. They are said to release low level toxic emissions long after they have dried on your walls. Paints with Low-Volatile Organic Compounds (Low-VOC and No-VOC) are the solution. You can feel the difference they are free from odor, thanks to the lack of harmful chemicals. Some of these eco-friendly paints are however expensive and may turn those on a budget off. But it is important to remember that it is almost impossible to create 100% non-toxic and non-allergenic paint even though manufacturers claim so. What can be done is to use paints that have a lesser concentration of the harmful elements which is effectively what the Low-VOC and No-VOC paints are.

Wallpaper

For those who would like a bit of vibrancy added to their walls, eco-friendly wallpapers are around. The problem with the regular wallpapers lies in the inks that are used while manufacturing. Eco-friendly wallpapers feature water-based inks; these inks are printed on chlorine-free paper obtained from forests specifically managed for the purpose. Low-VOC adhesive can be used for lightweight and medium weight paper-based wall decorations.

Carpets

Once you are done with the walls it is time to turn your interior design cravings to the floor. The pollution hazard with generally used carpets and flooring is that their installation can fill the indoor air with plenty of VOCs or volatile organic compounds. Included in these VOCs are carcinogens such as formaldehyde and benzene. You certainly would not want yourself or your loved ones to be inhaling these toxic substances. You ca not escape from it as these compounds could take years to dissipate, long after your flooring has been completed. What's more, the treatment employed to keep the carpets free from moths, soil and moisture involves toxic chemicals. The carpets themselves could attract toxic substances and VOCs from outside the house. The good news is that eco-friendly interior designs can be employed here as well. There is wide variety of eco-friendly flooring options that include bamboo, cork, recycled metal and glass tiles, linoleum, stones and sustainable and reclaimed woods.

Carpet Tiles

Check out modular carpet tile squares that can used in place of the traditional carpet, these tiles are held to the ground by adhesive dots. They resemble the conventional carpet when all the tiles fall in place together, but are made from totally recycled materials and can be recycled again and again square-by-square. If you've dirtied one square by mistake it can be given to be recycled while you get a new tile!

Uses for Bamboo

Bamboo is an excellent option for eco-friendly flooring as well. Interior designers could give you innovative ideas to use bamboo for not only flooring but an array of interior furnishings. Recycled metal tiles available in aluminum as well as brass from dealers are great for the bathroom, kitchen floors and walls. They are often thought of as fashionable interior design statements. Available in polished, matte or rough finish, they can satisfy the decorative tastes of many, especially offering a contrast with wood used elsewhere in the room.

Sustainable and Reclaimed Wood

Sustainable and reclaimed wood are great interior design options and they work for floors as well as furniture. Rapidly disappearing forests have spawned the need for sustainable wood products. These wood products are made with wood from managed forests. The difference between a regular and managed forest is that the latter is never destroyed in one clear sweep (clear-cutting) as is the case with other forests. Only selected trees are removed, leaving behind a variety of different tree species. Each area of forest is then managed and replanted giving a 30 years cycle of regeneration of the forest to be complete before the felling starts again. This system does not deplete the land of its tree cover and it also ensures a constant supply of wood.

Here's how interior designers can find out if the furniture or wooden accessories they purchase is made from wood from sustainable and managed forests. The Forest Stewardship Council (FSC) seal is one of the seals that are reliable, the other being Rainforest Alliance's "SmartWood", and the SCS and "Green Seal" labels from Scientific Certification Systems. FSC works globally to ensure responsible use of the forests of the world. The FSC certification only falls on forest managers and manufacturers who have satisfied the highest environmental and social standards in all stages of the wood production cycle, from the forest to the market through the factory. There's no better way to balance the interests of society, environment and industry.

Beds, bed frames, dressers, nightstands and accessories are all available from sustainable wood certified by the FSC and other organizations, while reclaimed wood products are also around. Reclaimed wood products are made from wood that have previously served in structures and flooring. No fresh tree is cut to create a reclaimed wood product.

And Finally...

If you make the decision to make the environment safer for everyone, there are plenty of options you can try out. Beginning with the floor, you can customize everything from furniture and accessories to flooring and walls. Newer eco-friendly ideas are set to come up in the market as well. Kick-start the eco-friendly revolution!

About the Author:
If you are environmentally conscious, currently live in South Wales in and considering hiring environmentally aware interior designers, many Cardiff Interior Designers and Swansea Interior Designers will be able to provide eco-friendly interior design services to suite your needs.

The first thing I should mention is insulation - it makes sense both environmentally and economically to make sure your house is well insulated before adding heat sources. Look to your cavity walls and roof insulation first as this is where adding insulation can be most effective.

Coal is a fossil fuel, a major source of CO2, and therefore contributes to climate change. Sustainably sourced wood is a renewable resource and in itself is carbon neutral. Once you add in the processing and transport of firewood it is not quite carbon neutral but still pretty close.

There are more commercial boilers available that will burn wood chip or wood pellets – I am not writing about these here but they can be a very good, low maintenance option.

When budgeting for a stove bear in mind that you may end up paying as much or more for your flue/chimney system.

Types of woodburning stove

When choosing your stove try to choose a dedicated woodburner instead of a multi fuel stove. A dedicated woodburner will be unlikely to have a grate in it which means even if you felt the temptation one cold night you would not be able to burn coal in your stove.

A dedicated woodburner is also likely to be the best type of stove to burn just wood in efficiently. This is because wood burns best on a bed of ash with a supply of air from above, whilst coal needs a supply of air from below (hence the need for a grate in multi fuel stoves).

Styles of stove

Traditional style stoves are box shaped with one or two doors at the front. They are either made of cast iron or steel. Steel used to be shunned as it often used to bend and burn out in when exposed to the high temperatures found inside a stove's firebox. Steel quality has now greatly improved so which stove you want is now more a case of quality and aesthetics. Cast iron stoves are sometimes built better than steel stoves (which is of course reflected in their price), but this is not necessarily to do with the fact that they are made from cast iron.

Common makes of steel stove available in the UK include Aarrow, Clearview, Hunter, Stovax, and Villager.

Cast iron stoves include Dovre, Franco Belge, Jotul, Morso, and Saey.

Prices range from around £300-£2000 depending on the make and model. As with anything else in life you generally get what you pay for although there are obviously some extra good value stoves to be found.

Modern contemporary designer stoves

Contemporary stoves tend to be tall and often with relatively small fireboxes. Contemporary stoves are usually very efficient and are cleanburning. Often the outer skin of the stove will be separate from the firebox making the outside of the stove cooler to the touch. With kW outputs in the range of 4 – 9kW these stoves are most often used as impressive secondary heating, or as heating in very well insulated houses.

Makes of contemporary stove available in the UK include Morso, Saey and Westfire. One of my favourite stoves is the Saey Scope which is kind of half way between a traditional and a contemporary stove. It weighs in at around 200kg of cast iron and is very good quality.

These stoves are often relatively expensive (compared with traditional stoves) with prices in the range of £800-£4000 depending on the make and model.

Second hand stoves

Stoves are of course available second hand on place like Ebay, gumtree, and free papers like Loot or Tradeit. You might also try Freecycle- it's worth a go.

Check the perishable parts like the grate, the firebricks, the baffle plate. These may need replacing and so bear in mind that you might also have to buy replacement parts. If many parts are perished then the stove may have been mistreated and perhaps you should go for another one. Look out for cracks on the body of a cast iron stove and look out for deformation of the body on a steel stove. Make sure that the doors close well and make a good seal to the body of the stove - door rope is easy and cheap to replace but if the door closes at a funny angle then that is not good.

Central heating stoves

Many traditional style stoves can come with a clip in or a wraparound backboiler. The backboiler is a metal envelope of water which replaces one or more firebricks inside the stove. Often backboilers are made of stainless steel or lined with some other material to slow down corrosion. The heat from the fire heats up the water which is then passed on to your hot water or central heating.

A stove usually needs to be connected to a vented system – this means that the heating system is not pressurised and you would also have a small header tank to keep the system topped up with water and to cope with changes in pressure. If you have an existing system with a boiler then if there is a pressure gauge on the boiler then you are likely to have an unvented, pressurised system and it will be hard to incorporate a stove with a backboiler into it.

The water from the stove backboiler can either be pumped around your system or the system may use thermosyphoning (the fact that hot water rises) to circulate the water. If thermosyphoning is to be used then the pipes for the heating loop should be larger than normal, ideally 28mm or larger. Either way you need to make sure that above the stove there is a radiator or water tank into which the hot water from the backboiler can go if your pump or electricity fails. If the pump is not working then you need to get rid of the heat from the backboiler somehow.

Stoves and other heat sources (e.g. Solar and a boiler) can be combined using multiple coil water tanks, accumulator tanks or similar. Always consult a competent heating engineer.

Makes of central heating stove available in the UK include Stratford, Dunsley, Hunter, and Villager.

My house is wood heated by two stoves one of which is made by Hunter – it is a Hunter Herald 14 stove with a wraparound 45,000 BTU boiler, the other is an antique range with custom made backboiler – both are hooked up to the central heating system.

Range cooker stoves

You will no doubt be familiar with the name Aga and Rayburn which are the traditional heavyweight range cookers made in the UK. These provide heating, hot water, a hotplate and ovens for cooking and are good stoves. European style range cookers are more lightweight, can be a bit more more controllable and are definitely cheaper.

Smoke control areas

Before you rush off and buy a stove remember that most towns in the UK are smoke control areas. This means that burning wood in them is illegal unless burnt on an "exempt appliance". There are many makes of stove which are smoke control exempt including stoves from Clearview, Dovre, Dunsley, Morso, Westfire and others too.

To check if you are in a smoke control area, or to see the list of exempt appliances simply visit: www.uksmokecontrolareas.co.uk.

Getting the most out of your stove

A woodburning stove is best run with a good supply of air so that there are lots of flames visible in the firebox without smoke. However you should not run the stove at full blast all the time as this can be bad for it and is a sign that you probably need a bigger stove.
Slumber burning is very inefficient as you are not getting full combustion of the wood (because you have limited the air supply), so try to avoid slow overnight burning. Slow burning will also tend to tar up your window (even if your stove does have an airwash system) as well as your chimney (leading to an increased risk of chimney fire).
When burning wood use the top air inlet and burn the wood on a nice bed of ash.

Independent stove reviews

www.whatstove.co.uk is the UK's only stove review website. Manufacturer's blurb and salesman's wording are no match for actually using the stove. On Whatstove you can read a growing number of reviews left by people who actually use and own stoves.
If you own a stove please leave a review to help others make an informed choice.

Buzz words

Cleanburning
A second supply of usually preheated air is introduced into the firebox. Unburnt flue gases are combusted. In efficient stoves (like the Morso badger) you can see flames hanging in the air as the gases burn. This increases the stove's efficiency and heat output.

Airwash
Air is passed over the window of the stove to reduce tar deposits. This works fairly well as long as you do not turn the stove down too much (for slumber/overnight burning).

Grate
A series of metal bars on which coal is burn. The bars allow a flow of air to the bottom of the firebox which is needed for burning coal. Wood does not need to be burnt on a grate.

Baffle plate
A plate of metal or vermiculite placed at an angle at the top of the stove. This increases the distance travelled by the gases in the firebox before they can escape and therefore extracts more heat from the fuel into the room.

Clip-in
A boiler that can be retrofitted - fitted into an existing stove.

Wraparound
A boiler that goes around several sides inside the firebox (typically 3 sides) and is factory fitted.

BTU
British Thermal Units are a measure of heat. 10,000 BTU are roughly equivalent to 3kW (being pedantic it is more like 2.93kW).

As the title states, why should we consider buying our babies clothes and toys made from organic cotton? We look with interest at organic baby foods such as rice and vegetables as we worry about feeding our babies food containing too many chemicals. We do not think as much about the benefits of buying products made from organic rather than conventional cotton.

Did you know that 25% of the world’s pesticides used have been sprayed on cotton? In fact it takes a cup full of chemicals just to make one child’s t-shirt. - Shocking really. The consequence? According to the World Health Organisation 20,000 deaths occur in developing countries each year due to pesticide pollution, many of these deaths as a direct result of producing cotton. In addition, research carried out by PAN UK suggests 3 million people suffer after effects of cotton production. Pesticides also damage the soil fertility, destroy wildlife and cause chronic disease both to the farmer and his family.

The chemical process doesn’t stop there. Non-organic cotton products are then coloured with toxic dyes. For example, Dioxin, a bi-product of bleach is used to whiten clothing and formaldehyde can also be used to make the clothing more presentable. A baby’s skin is five times thinner than an adult’s making it easier for chemicals to be absorbed into the bloodstream.

There are other benefits to choosing organic clothes and toys for our children. With organic material, you are getting a far softer, stronger, better material because the cotton fibres are left intact and not broken down by the chemicals used in the farming and processing of conventional cotton. Organic cotton also smells nicer as formaldehyde is not used to finish the product. It is also less likely to trigger allergies as there is an absence of chemicals and an increased breathability in organic cotton.

Whilst parents have the right to choose the products they purchase for their children, this should be an informed choice, having being presented with the facts of cotton production.

At Baby Treasure Trove we stock a wide selection of organic clothes, toys and accessories. Please visit us at www.babygifts-treasuretrove.co.uk.

What is ethical fashion, why is it important, and why are we just hearing about it now? Well, to answer these questions we start with what is wrong with clothing production today. Most clothing available in stores today is produced in an unethical manner using sweatshop and/or child labour to ensure a larger profit margin. Manufacturers use unsustainable fabrics like non-organic cotton (dubbed as natural, it accounts for almost 25% of all pesticide use) and polyester (which is a petroleum by-product). They use conventional dying practices which release chlorine, chromium, and other pollutants into the environment posing a health risk to the farmers, assemblers and wearers (7 of the top 15 pesticides used on conventional US cotton crops are "possible" to "known" human carcinogens). The shift to ethical production practices in the clothing industry has been undeniably important for a long time making the market ripe for a positive change. Consumers are starting to demand better.

What is Ethical Fashion?

Ethical fashion is that which is produced using: fairly-paid and fairly-treated adult workers; sustainable fabrics and materials like organic cotton, hemp, bamboo, and reclaimed or recycled materials; low-impact fiber-reactive dyes or vegetable dyes; respect for a healthy environment and/or product for the farmer, the assembler, and the wearer of the clothing.

Why Ethical Fashion?

We are all responsible for how our own lifestyles affect the environment. Simple measures can be taken to achieve big changes by simply switching our buying patterns to include products made of low impact materials. Positive pressure on businesses who have yet to volutarily clean up their acts is very easily applied by simply choosing not to spend money on their products, and helping – little by little – to grow the businesses who have made an explicit commitment to responsible business practice.

Why Now?

The wonderful thing about the booming ethical fashion industry is the huge variety of designs, colours, cuts, fabrics and sizes now available. Long stigmatized as cousin to the burlap sack, the ethical offerings today are design-oriented. Designers with heart are creating beautiful, sexy, edgy, classic, current, imaginative, and, yes, flattering pieces – ethics will simply not be compromised and thankfully neither will the look and feel of their work. Reducing our footprint can be done without making any sacrifices.

One of the main driving forces of the ethical fashion boom is public awareness. Thanks to expos�s on large manufacturers, the fact that sweatshop labour is used for the overwhelming majority of production can no longer be ignored. The power of boycotting has been demonstrated, as has the power of voting with our dollars to support good practice. Thanks to accessible work like "An Inconvenient Truth", the lay person is no longer free to assuage their environmental guilt with the denial of the existence of climate change. Thanks to alternative medical practitioners, who deal with cause instead of just symptom, we're learning that we can build health by surrounding ourselves with and consuming healthy things.

Consumers are growing weary of the quantity without quality mentality. Most designers with an ethical bent to their art, work in small batches, producing high quality goods with exceptional fabrics. Consumers are, in growing numbers, appreciating the right to vote with their dollars; and are exercising it to support expansion of the sustainable textile industry, small farmers and farm co-operatives. We're all looking for ways to reduce our environmental impact, increase our social contribution, ease our consciences, hold on to some creature comforts, and continue celebrating art in all its forms.

Wood fuel comes in many guises most commonly logs, pellets and wood chips. This article discusses logs. Heating your home with a wood burning stove is becoming increasingly popular. According to the forestry commission around 7% of UK homes currently use wood fuel in their homes to provide some or all of the heating. Not only is a stove cosy to sit around, wood is also a very low carbon fuel so you can do something to shift away from fossil fuel reliance.

In many cases trees are not felled primarily for firewood and it is the leftovers that are used for burning, for example the bark and sapwood that does not make for good building timber.

Wood fuel as it relates to C02 and global warming

Trees use the power of the sun to trap C02 from the air and convert it into more complex carbohydrates, combining the carbon from C02 with hydrogen from water (H20) and releasing the leftover oxygen in a process called photosynthesis. Trees use these carbohydrates to grow. Most of a tree is in fact trapped C02. When the tree is then burnt the C02 is released once again. In a sustainably managed forest each tree that is cut down is replaced so this results in no overall change in atmospheric C02 levels (not counting the C02 produced as a result of processing and transport).

Heating with wood is not carbon neutral (as many people do try to claim) because there is the processing and transport of the wood to consider, but compared to the C02/kWh of many other fuels wood does very very well indeed.

Global warming caused by human C02 emissions is already happening - if you doubt this then read through the Intergovernmental Panel on Climate Change (IPCC) report available from www.ipcc.ch. Switching your heating away from fossil fuels is one way in which you can help reduce C02 emissions and thereby slow global warming.

Insulate your house

In conjunction with changing your heating fuel you should also take steps to better insulate your home and thereby reduce your fuel needs. This includes improving your roof insulation, wall insulation, floor insulation as well as installing double glazed windows and draft proofing windows and doors. Not only will this reduce your C02 emissions but your fuel bills will also drop. Read this article about insulation.

Firewood

There is still a lot of sustainable firewood available in the UK with further unexploited capacity remaining. When sourcing your wood try to source from local suppliers as opposed to national suppliers that delivery by pallet. It is all very well burning wood to reduce C02 emissions but if the wood is being driven 500 miles to your door then it kind of defeats the point.

Seasoned firewood

It is very important that your firewood is well seasoned. Seasoned firewood is dry and ready for burning: it has been split to size and stored to dry for at least the summer season. This reduces the wood's moisture content down to reasonable levels for burning – typically 20% or lower. Very dry wood (such as wooden furniture in your house will have a moisture content of 10% or lower).

A sign that wood is seasoned is that the end grain of the logs may have small cracks in it (these cracks form as the wood shrinks due to water loss).

Another way to check is to split open a log and then use a moisture meter to measure the wood's moisture content. 20% or below is OK, above 20% not great, above 30% do not buy it (or be aware that it is unseasoned and will need storing before it can be burnt. You should not pay as much for it as for seasoned firewood).

Un-seasoned wood with a moisture content above 20% is not really suitable for burning and can be dangerous. A lot of the heat of the fire will be used to evaporate the water in the wood which means that your stove will run colder and you will not get as much heat for your money. The flue gases will also be colder as a result and you will get a LOT more tar condensation in your chimney which you want to avoid as this tar is the cause of chimney fires.

I will expand on chimneys and flues in another article.

Storing your firewood

I have a log shed where I keep my firewood. Ideally your shed should be fairly big – enough for a couple of tonnes of wood (don't worry that isn't as big as it sounds) so about 2 to 4 cubic meters.If you do not have the space then make it as big as possible – this will reduce the amount of firewood deliveries that you need every year. Your log shed should be sheltered from the rain but have sides that allow the wind to blow through as you want the wood to keep drying while you store it: the lower the moisture content the better it will burn. Recyclers amongst you might consider making the walls of your wood shed out of old pallets as these work very well and let air through at the same time. At the front of my shed I have some removable boards. I add these when the shed is very full to stop the firewood falling out of the front of the shed and then take them off as it empties as this makes it easier to reach in and get at the wood.

If space is limited the perhaps consider storing your wood against a wall with a small, simple roof above.

If you fell your own wood then the best thing to do is to split it immediately and then store it. If this is not possible then store it under cover and make sure you split it as soon as you can, storing it split for as long as possible. Some people store larger timbers in situ, putting down a couple of timbers on the ground to raise the pile off the earth and then covering the top with corrugated sheeting or similar to form a waterproof roof.

Splitting and chopping your wood

I use two types of axe to split my firewood. Outside I use a heavy maul which is a wide headed large axe to split oversize logs. A raised flat platform like a very large log is an ideal surface to chop wood on. The surface should be hard so that the energy from the axe transfers into the wood you are chopping and not into your chopping block. Inside I use a hatchet to make kindling to start the fire with. You might do this outside as it can cause mess and damage your floor.

Types of wood

Softwoods like pine burn fast and fairly hot and make good kindling to start your fire with. But pine will not last that long so once your fire is going you are better off switching to a hardwood. Hardwoods (like beech, ash, oak, chestnut) burn for longer and are ideal once the fire is going. Ash is great for burning and when freshly cut has a moisture content that can be as low as 30% which means that it takes less time to season than other, wetter woods. I personally like oak as it lasts for a long time because it is a very dense wood.Treated woods should not be burnt as noxious chemicals are released into the atmosphere. This is the problem with wood from building sites, skips and so on as you cannot be sure that it is untreated.

Finding a UK firewood supplier

There are a couple of searchable firewood supplier listings available online. The most up to date one, which is also free for firewood suppliers to join, can be found by following this link: UK Firewood supplier search.

You enter the first part of your postcode and then click 'search'. Firewood suppliers that deliver in your area are listed with the ones with fewest delivery areas displayed first (so the most local suppliers are listed first).This is a free service so if you are a firewood supplier and would like to be listed simply visit the page and fill in the simple application form.
