Production of hemp material is considered to be eco friendly because the hemp production generates some environmental benefits:

Pollution free: Hemp is such as hardly plant that can grow almost anywhere at any climate; it hardly needs fertilizer, herbicides or pesticides, so it reduces the pollution to the earth, air and water; but this is not all. Hemp itself actually cleans up toxins from the ground, under a process namely phytomerediation. Chemical pollution can also be significantly reduced if displace cotton with hemp for clothing, as 50% of the world’s pesticides goes on cotton fields.

Sustainable Agriculture: Not just can be grown without fertilizer, hemp plant also replenishes soil with nitrogen and nutrients, increases the topsoil, and restore the health and fertility of the soil that makes hemp farming becomes a sustainable agriculture.

Erosion control: Hemp tree has long roots that firmly hold the soil which help control the erosion.

Carbon Sequestration: Due to its fast growth, hemp may also be useful in carbon sequestration – absorbing carbon from the air and storing it back into the earth.

Clean industry: Processing hemp fiber for paper and cloth does not require chlorine that produces dioxins as it does with wood or cotton fiber. Paper industry which today mostly uses wood pulp has now become the 3rd largest polluter. Switching to hemp fiber will make an immense improvement to our Earth.

Eco Fuel: As biodiesel fuel, hemp fuels emit 80% less carbon dioxide with almost no sulfur dioxide compared to fossil fuel. This makes hemp flues do not destroy the ozone layer, generating less greenhouse gas nor causes acid rain that contribute to global warming and climate change. Hemp fuel even found to be 10 times less toxic than salt and as biodegradable as sugar!

Water-saving: Hemp plant helps the water crisis that the Earth is facing now, because it does not need much water to grow. Compared with other wood and cotton plantation, hemp requires much less water.

Land – saving: 1 acre of usable hemp fiber is equal to the usable fiber of 4 acres of trees or 2 acres of cotton. Using hemp could save the land cleared for agriculture means; hemp production could reduce the deforestation.

Durable products: Hemp produces stronger fiber than most other plants, and can be recycled many more times than other products can. Therefore hemp products are supporting the ” reuse, reduce, recycle” of the eco living.

Efficient Land Use: Hemp can yield four times of an average forest can. A hemp crop can be harvested in ninety days, while trees take around twenty- five years. Just imagine, once we harvested the forest, it will need some 25 years to recover the deforestation.

Oxygen release: Hemp trees are proven to release lots of oxygen.
