The answer, as James put it, is likely because it is perfect for the job.
Here is some info!
Paper made from hemp lasts hundreds of years longer than wood-pulp paper, which decomposes and yellows with age. Hemp paper resists decomposition and does not yellow with age.
“While the hemp paper in volumes 300-400 years old is still strong, 97% of the books, printed between 1900 and 1937 on tree paper, will be useable for less than 50 years.” Hemp paper can be recycled 7 to 8 times, compared with only 3 times for wood pulp paper.
The USDA reported in 1916 that an acre of hemp produced as much paper as four acres of trees annually , yet 70% of American forest have been destroyed since 1916.
Hemp paper doesn’t require toxic bleaching chemicals. It can be whitened with hydrogen peroxide, which doesn’t poison waterways as chloride and bleach--the chemicals used in making wood pulp paper--do.
On the other hand- 3 million tons of chlorine, a major source of carcinogen dioxin, is dumped into our waterways each year from paper companies. Every woman alive today carries some trace of dioxin in her breast milk. Dioxin is considered one of the most toxic substances ever produced = cancer, liver failure, miscarriage, birth defects, and genetic damage.
Hemp as a bio-fuel
- Hemp grown for the production of biomass fuels can provide all of our gas, oil and coal energy needs and end dependency on fossil fuels.
- Hemp results in a 95.5% fuel-to-feed ratio when used for pyrolysis the thermochemical process that converts organic matter into fuel.
- Biomass has heating value of up to 8,000 BTU/lb., with virtually no residual sulphur or ash during combustion.
- Biomass fuels offer a clean alternative to fossil fuels. No sulphur oxides are released, either during pyrolysis or combustion
- Hemp is the #1 producer of biomass per acre in the world.
- Hemp is very easy on the soil and returns up to 60% of the nutrients it takes from the soil, when dried in the field.
- A report from Kentucky states that hemp was grown on the same land for 14 consecutive years without soil depletion or reduction in yield.
- Hemp is very economical crop to grow since it requires virtually no pesticide applications.
- Hemp is also relatively drought-resistant and has been relied upon several times during drought-induced famine for its high protein seed.
- Hemp is very resistant to increased UV radiation and should not suffer decreased yields, unlike soya bean and corn.
