Natural Homes Around the World

Thursday, January 31st, 2008

Here’s a nifty little map that Natural Homes have put together, that displays some of the natural homes around the world. Homes include those made using straw bale, hemp, timber, earth, straw clay, cordwood, as well as solar panel homes.

On the map, each house is represented by an icon (indicating what it has been built from). Click on each icon to learn more about the house:

What is Hemp?

Thursday, January 31st, 2008

Hemp is the common name for the cannabis family of plants, although the word is typically used in reference to industrial hemp.

What is Industrial Hemp?

The term industrial hemp refers to cannabis strains cultivated for non-drug usage. Industrial hemp is usually referred to, simply as hemp. Most of the time, when someone talks about hemp, they are referring to industrial hemp.

Hemp is an extremely versatile, natural fiber. It is sometimes referred to as a “super fiber” due to it’s amazing range of benefits and attributes. Hemp is the strongest natural fiber in the world, and it has been cultivated for a wide variety of purposes for thousands of years. In fact, the earliest known woven fabric was made of hemp over 10,000 years ago.

In recent years, hemp has been gaining a reputation as an environmentally friendly alternative to many other fibers. For example, hemp clothing and accessories are becoming popular alternatives to their cotton or polyester counterparts.

Despite hemp’s usefulness, it is often misunderstood. Because hemp is closely related to marijuana, some people assume it can be misused (i.e. for drug use). The fact is that industrial hemp doesn’t contain enough tetrahydrocannabinol (THC) to make it a psychoactive drug (such as marijuana).

Environmental Benefits of Hemp

To say that hemp is environmentally friendly is an understatement. Hemp contains so many environmental benefits, it’s amazing it’s not more popular. Hopefully this will change as the climate change / global warming debate heats up further.

For starters, hemp can be grown in most climates, without pesticides, and uses very little water. Also, hemp products are 100% biodegradable.

Here are some more of hemp’s environmental benefits.

Hemp Laws

Currently, hemp is allowed to be grown virtually anywhere in the world - except the U.S.. In the U.S. hemp cultivation is now illegal. This is unfortunate given the enormous environmental benefits to be gained from industrial hemp.

Hemp wasn’t always illegal in America though. Here are some interesting facts about hemp laws and usage in the U.S.:

  • The first American flag was made from hemp.
  • The U.S. Constitution and the Declaration of Independence were drafted on hemp, and then copied onto parchment.
  • U.S. presidents George Washington and Thomas Jefferson both grew hemp.
  • Benjamin Franklin owned a mill that made hemp paper.
  • During the second world war, the U.S. government actually subsidized hemp.
  • During the Colonial Era and Early Republic, American farmers were legally bound to grow hemp.
  • In 1937, hemp cultivation was outlawed in the U.S..
  • Although it’s illegal to grow hemp in the U.S., it’s not illegal to import or use products made from hemp.

Given the obvious environmental benefits of hemp, and the non-issue regarding it’s association with marijuana, the U.S. hemp laws are apparently in urgent need of review.

As Thomas Jefferson once said “Hemp is of first necessity to the wealth and protection of the country

…or as George Washington said, “Make the most of the Indian Hemp Seed and sow it everywhere“!

Uses for Hemp

Being such a versatile fiber, there are literally thousands of uses for hemp. Many people claim that there are over 25,000 known uses for hemp!

Without naming all 25,000 uses(!), hemp can be used in a wide range of areas including consumer textiles (eg, clothing, bags), industrial textiles (eg, ropes, nets), food (eg, oils, supplements), body care products (eg, soap, shampoo), and building materials (eg, fiberboard, hempcrete).

Environmental Benefits of Hemp

Thursday, January 31st, 2008

Industrial hemp is gaining a lot of respect around the world for its amazing versatility and environmental benefits. Many companies are turning to hemp in order to make their products more sustainable and eco-friendly in general.

Unfortunately, widespread acceptance of hemp still has a long way to go. Many people are oblivious to the great benefits of hemp. Some (incorrectly) assume that it’s a drug (because of its close association with marijuana). The U.S. government has even made it illegal to grow hemp. This does not make it easy for those of us who are trying to do the right thing!

Hemp cultivation can provide many benefits for the environment. Also, hemp products can provide further environmental benefits when comparing them to products made from other fibers.

Here are some key reasons why hemp should become much more widely used than it currently is.

Growing Hemp

Here are some of the major environmental benefits of growing hemp:

  • Fast and robust growth: Hemp grows extremely fast and can be grown in any climate, in any agronomic system
  • No herbicides/pesticides required: Hemp can be grown with no (or little) herbicides, fungicides, pesticides, or other biocides.
  • Suppresses weeds: Hemp is a natural weed suppressor due to the fast growth of the canopy. Actually, hemp is a weed. Because it grows so fast and densely, it blocks out sunlight to other weeds that are trying to grow.
  • Improves soil structure: Due to it’s long roots, hemp replenishes soil with nutrients and nitrogen and helps control erosion of topsoil. Also, once harvested, any residue can act as an eco-friendly manure.
  • Hemp produces lots of oxygen: Hemp produces the same amount of oxygen while it’s growing that it would use in carbon dioxide if burned as a fuel. Also, due to it’s leaf/root ratio (this can often be 10% roots vs 30% leaves), hemp can produce between 20% - 40% more oxygen than will be polluted.
  • Cleans up pollution: Hemp can actually clean up toxins from the ground. This process is called phytoremediation. A good example of this is when hemp was used to help clean up the Chernobyl nuclear disaster site to remove radioactive elements from the ground.

Hemp Products

Naturally, products made from hemp are 100% biodegradable, recyclable, and reusable. Also, the speed at which hemp grows can provide benefits regarding the resource requirements of the end product.

Here are some examples of how hemp products could benefit our environment and our health:

  • Switching to hemp paper could reduce deforestation significantly. For every 4 acres of trees that are required annually to make paper, only an acre of hemp would be required. Furthermore, because hemp paper can be recycled so many times (up to 7 or 8 times), much less is needed. In comparison, paper from wood pulp can only be recycled around 3 times. This means even more trees are required.
  • Clothing and textiles made from hemp have no residual chemicals that could affect our health (as many other fabrics do).
  • Hemp based fabrics block the sun’s UV rays more effectively than other fabrics. This is true, even if it’s only a 50% blend with another fabric.
  • Hemp oil is the richest known source of polyunsaturated essential fatty acids (the “good” fats)

It’s widely known that hemp can be used in so many ways as an eco-friendly alternative to current methods. Given that so many of today’s products are produced from toxic materials, by switching to hemp based products, the benefits for the environment (and ourselves) would be enormous.

Some Hemp Trivia

Thursday, January 31st, 2008

Hemp is renown for its extreme versatility and eco-friendliness. Given the rising interest in hemp, particularly as an eco-friendly alternative to so many other ingredients, I thought I’d gather together a bit of hemp trivia.

Here are some interesting facts about hemp:

  • Hemp is the strongest natural fiber in the world
  • The earliest known woven fabric was made of hemp over 10,000 years ago (possibly even 11,000 or 12,000 years ago)
  • The original denim jeans by Levi Strauss were made out of hemp, due to its durability.
  • Hemp was used to help clean up the Chernobyl nuclear disaster site (due to its ability to suck radioactive toxins out of the ground).
  • The word “canvas” is derived from the word “cannabis”. This is because hemp was originally used to make canvas.
  • Car manufacturers such as Ford, GM, Chrysler, Saturn, BMW, and Mercedes are using hemp composite in various parts of their vehicles
  • Companies such as Calvin Klein, Ralph Lauren, Giorgio Armani and The Body Shop are all starting to use hemp in their products

And, isn’t it so ironic that hemp cultivation is now illegal in the U.S. given it’s permanently etched into the history of the U.S.A…..

  • The first American flag was made from hemp.
  • Both the U.S. Constitution and the Declaration of Independence were drafted on hemp, and then copied onto parchment.
  • U.S. presidents George Washington and Thomas Jefferson both grew hemp.
  • During the second world war, the U.S. government actually subsidized hemp.
  • During the Colonial Era and Early Republic, American farmers were legally bound to grow hemp.
  • Thomas Jefferson once wrote “Hemp is of first necessity to the wealth and protection of the country
  • U.S. president George Washington once wrote, “Make the most of the Indian Hemp Seed and sow it everywhere!

What is Organic Linen?

Thursday, January 24th, 2008

Organic linen refers to linen that is made from plant fibers as opposed to synthetic means. But more importantly, the plants have been grown without the use of toxic pesticides and fertilizers.

The term “linen” is often used in a generic sense to describe a certain textiles such as bedding, table cloths, towels, etc. This is quite a general use of the term and it doesn’t refer to what the term “linen” was originally used for. Linen originally referred to yarn and fabric made from flax fibers (from the flax plant).

These days linen could be made from flax fibers, cotton, hemp, or it could be synthetic. Therefore, the term linen is now a little ambiguous.

If you are a purist, you might say that true linen is made from flax fibers.

Where Can I get Organic Linen?

Nowadays, there are plenty of products on the market made of “organic linen” or “eco-friendly linen”. While some of these products may be made from flax fibers, many of them are made from other fibers.

  • Crespi1797, a company from the 18th century, continue to produce pure linen made from flax
  • MikkaWork, a Chinese company, make organic linen
  • Australian company, ecoLinen uses organic cotton in their eco-friendly linen products. ecoLinen are the first linen company in Australia to be certified organic by SKAL International
  • Rawganique produce organic clothes, towels, and bedding. They use use flax linen as well as hemp and organic cotton in their products

Quiksilver’s Eco Friendly Winter Clothing

Tuesday, January 22nd, 2008

It was nice to read about Quiksilver’s new eco-friendly winter outwear clothing today.

On January 29, Quiksilver will launch a whole new line of eco-friendly winter wear. As mentioned in the article, winter wear has traditionally been the least eco-friendly, so it’s great to see a prominent clothing company like Quiksilver getting stuck into the challenge of providing eco-friendly winter wear.

Here are some eco-friendly fabrics that Quiksilver uses in their clothing:

  • Biodegradable TPU Laminate
  • Nanosphere Finish
  • Organic Cotton
  • Hemp
  • Non-Toxic Dyes
  • Recycled PETs-Recylced Polyester and Soda Bottles

Eco Friendly Grocery Bags

Sunday, January 13th, 2008

In my post How “Eco Friendly” is your Grocery Bag?, I suggested looking for an eco friendly grocery bag. In particular, I suggested looking for a bag that is made from natural fibers, is large, and can be reused over many years.

In this post, I will look at some of the options when it comes to eco friendly grocery bags.

Eco friendly bags come in a wide range of different materials. Here are some eco friendly bags available on the current market:

  • Hemp bags
  • Calico bags
  • Jute bags
  • Hessian bags
  • Biodegradable starch based bags
  • Polyester bags
  • Biodegradable plastic bags
  • Degradable plastic bags
  • Paper bags
  • “Green bags”, such as the one’s introduced at supermarkets in Australia. Note that these are typically made from polypropylene so they’re not really eco-friendly. But they are re-usable and hold more than a typical plastic bag.

These eco friendly bags have varying levels of “eco friendliness”, but are typically regarded as being much better than their traditional plastic bag alternative (with the possible exception of paper bags). Despite paper bags having a more eco friendly image, studies show paper bags are less eco friendly than plastic bags.

While some of the above don’t decompose properly (i.e. polypropylene, paper), others are made from natural fibers and decompose very easily. Biodegradable plastic bags are best suited to composting (as opposed to landfill). Degradable bags on the other hand, are well suited to landfill. They basically self destruct after a given period of time - say 18 months.

The Benefits of Hemp

Hemp is a perfect choice for an eco friendly grocery bag. Hemp is a natural fiber and is very durable.

In fact, it’s the longest, strongest most durable natural fiber known to mankind. Also, Hemp can be grown in 2 months and does not require herbicides or pesticides.

Although eco friendly grocery bags can be more expensive than other types, you get a lot more use out of them. For example, a hemp grocery bag could cost you say, $8 - $10, but it will last you many years.

Another Option - Banana Leaves

You could always take a bunch of banana leaves to the supermarket with you. In fact, that’s what the Ugandan government is asking it’s people to do. In Uganda, banana leaves is the traditional method for carrying goods, and now that plastic bags have been banned there, banana leaves are back.
