The current rate of plastic production is about one billion tons in three years. That is what a 2016 article in ScienceDaily says, quoting a University of Leicester study.

Plastic is inert and hard to degrade. So it becomes a toxic techno-waste that has severe polluting effects on the earth’s biodiversity.

A National Geographic report says that plastic kills millions of marine and land animals every year. Experts have found out that all species to have eaten microplastic – from small shrimps to big elephants. The effects vary from damaging the digestive and reproductive systems to death.

But Mother Nature has provided a simple solution to this menace: the hemp plant.

Hemp: A Victim of Human Folly

Hemp, or industrial hemp, is one of the earliest plants that our ancestors cultivated and used.

Archeologists have found evidence of the use of hemp fiber some 10,000 years ago. Experts estimate that hemp cultivation began about 8000 years ago.

The many benefits of hemp have been available to human beings for centuries. But its cultivation and use were banned in most countries across the globe in the 20th century. The only crime of the plant is that it belongs to the same species, Cannabis Sativa, as marijuana.

THC

But there is a significant distinction between hemp and marijuana. That is in the concentration levels of tetrahydrocannabinol (THC), the component that gives marijuana its psychoactive properties. Marijuana can contain up to 30% of THC per dry weight.

Hemp, in contrast, contains 0.3% THC per dry weight. It does not have the psychoactive potential to get people high. Hemp got banned because this vital difference got overlooked.

The 21st century has, at last, brought a realization of this mistake. Many countries across the globe have now legalized hemp farming and the production of hemp derivatives fully or partially.

With the Agriculture Improvement Act of 2018 (Farm Bill 2018), hemp is now legal across the USA. It is also legal in the EU countries as long as the THC content is 0.2%. It is legal in Canada and several other European and South American countries.

In Asia, China is the biggest grower and supplier of hemp and hemp products across the globe. China also has the longest history of continued hemp production for almost 6000 years.

Hemp Against Plastic Pollution

People had hailed the 1907 innovation called synthetic plastic as a solution to a wide range of problems. It has now become an unmanageable problem itself. But we do not need any technological innovation to counter it. The hemp plant offers a ready solution.

Hemp fiber can produce a non-toxic and fully biodegradable substitute for plastic. Natural plastic derived from the cellulose fibers in plants has been in use since much before the current petrochemical-based synthetic plastic was invented.

Hemp Plant

The cellulose fiber in plants is usable for producing several varieties of biodegradable plastic. Hemp has about 65-70% cellulose, which makes it a viable plant for natural plastic production.

Henry Ford produced the original Model T Ford in 1941 using hemp plastic panels. This plastic was 10 times stronger than steel in withstanding the impact of a hit without denting.

Substituting synthetic plastic with 100% biodegradable hemp plastic will be a blessing for our plastic pollution problem and for our environment. Apart from being eco-friendly, hemp is also sustainable.

Why is Hemp Sustainable?

Hemp is sustainable for a variety of reasons. Apart from being a natural source of non-toxic biodegradable plastic, the hemp plant helps in topsoil conservation. Farmers use hemp as an in-between crop to keep their soil fertile.

Hemp cultivation needs 50% less water than cotton. Hemp is totally free from pesticides because it is naturally insect resistant. It is also easy to grow hemp plants organically.

Hemp is a source of paper more efficient than other trees currently used for paper production. One acre of hemp can produce four times more paper than an acre of trees. Incidentally, the first paper ever used was in China, and it was hemp paper.

Hemp is also a source of biofuel. If we use biofuel derived from hemp, our transportation fuel will be 86% greener than gasoline. It is not for nothing that Henry Ford designed his first Model T hemp plastic car to run on hemp biofuel.

But the benefits of the humble hemp plant do not end here.

The Many Benefits of Hemp

Hemp seeds are highly nutritious and constitute a source of complete plant-based protein. The omega 3 and omega 6 fatty acid content of hemp seeds is precisely the right proportion (1:3) that the human body needs. Hemp Seeds are ideal for vegans as no other plant-based protein is so complete.

Dehulled or unshelled hemp seeds are also rich in fiber. Hulled or shelled hemp seeds lack in fiber content. But even hulled hemp seeds are high in nutrition value. These seeds are also extremely versatile, usable in several ways – cooked or raw.

Hemp seed oil is also equally nutritious with a high content of good fats and a low content of the harmful ones. Cold-pressed hemp seed oil preserves the goodness of the oil in its entirety. Like the seeds, the oil derived from hemp seeds is also versatile.

Hemp seed oil is edible and can be taken by itself or as a salad dressing. It is also good for cooking, except for deep frying. Topical use of hemp seed oil can improve hair and skin health. It also has anti-inflammatory properties.

The cannabinoids (CBD) derived from hemp buds, flowers, leaves, and stems have much medicinal potential. CBD oil is particularly good for arthritis. Healthcare professionals have also used it with success to manage anxiety and sleep disorders.

Hemp stalks yield fibers that can be processed into fabric for clothing. Hemp fiber is also used for making ropes and sails. All of these products have natural antibacterial and antifungal properties. Incidentally, canvas is made of hemp fabric.

Finally, hemp can also be used as a building material. There are amazing benefits attached to this use as well.

This easy to grow plant seems to provide an environmentally sustainable solution to many problems we’ve created for ourselves not limited to plastic pollution!
