4 Ways Hemp Could Build A More Eco-Friendly Economy

Some of the biggest pollutants can be made from eco-friendly hemp. Not only is hemp the source of CBD, but its seeds and fiber can make of the modern necessities — concrete, plastic, fabric, and fuel — that we depend on. Hemp alternatives are better for the planet, as well as less toxic for the consumer.

What makes hemp such an eco-friendly alternatives? Hemp, not to be confused with the psychoactive plant cannabis (which is commonly known as marijuana), is one of the oldest farmed crops in the world. People have been farming hemp since 4000 BCE, by most estimates. In addition to its medicinal uses, this unique plant has applications as relevant today as they were during the Bronze Age.

Hemp thrives without pesticides.

One of the modern benefits of hemp is that it doesn’t require pesticides or herbicides to grow on an industrial scale. The environmental impacts of  pesticides are well-documented. They cause illness, reduce biodiversity and contaminate water supplies, the air and soil.

Many of the largest industrial crops, including soybeans and cotton, are farmed using significant amounts of pesticides. If even a fraction of these crops were transitioned to hemp, it would have a drastic impact on global pesticide use.

Hemp requires little water.

The agriculture industry uses approximately 70 percent of the world’s freshwater supply, according to the World Bank. As the global population expands (estimated to reach 10 billion by 2050), our demands for food and fresh water will grow accordingly.

In other words, our need for crops that use less water grows with every season. By most estimates, hemp is considered a non-water intensive crop. This makes it a more sustainable choice than cotton, especially.

A sustainable fuel source.

The environmental impacts of fossil fuel emissions and oil extraction are widespread. By contrast, hemp is a practical source for biodiesel, a type of fuel made from plant matter.

According to a study conducted by the University of Connecticut, the problem with most biofuel is that it takes up valuable cropland typically used to farm food. But because hemp can grow in poor soil and in a variety of climates, farming it does not allocate valuable farmland from other crops.

Additionally, this biofuel is derived from the seeds rather than the plant stock. Typically, seeds are disregarded, so reappropriating them as fuel is yet another way that hemp’s versatility makes it an eco-friendly crop.

Cheaper, more durable building materials.

Worldwide demand for concrete and cement is predicted to increase by 7 percent annually through 2020. Cement, the primary ingredient in concrete, is the second most consumed resource worldwide, and the second largest producer of CO2 emissions at 8 percent (according to the Royal Institute of International Affairs).

Hempcrete, a type of concrete made from hemp, is already in use around the world, especially in France. It’s less brittle than concrete and can be used simultaneously as a form of insulation and way to regulate moisture.

Though hempcrete is not suitable for building foundations it is ideal for non-load bearing walls and is a very good insulation.

An alternative to cotton.

Cotton is the most popular non-edible crop in the world but not only does cotton farming exhaust soil fertility, the pesticides commonly used in its farming are widespread freshwater pollutants. Cotton accounts for 11 percent of pesticides and 24 percent of insecticides used in the world, according to the World Resources Institute.

In addition to requiring pesticides and insecticides to thrive, cotton also requires a significant amount of water. It takes 2,700 liters of water to manufacture one cotton t-shirt — that’s roughly equal to what one person would drink in two-and-a-half years. Though a less common material than cotton, hemp is a traditional fiber commonly used to make fabric. However, it’s distinct from cotton in that it uses a quarter the amount of water, according to research.

Not only does it take less water, but hemp requires less land per pound of fiber. It can also grow in a variety of different climates.

Biodegradable Plastic

According to the United Nations, more than 8.3 billion tonnes of plastic have been produced since the 1950s. It’s estimated that half of all plastic is single-use, and 60 percent of it ends up in landfills or in nature.

Hemp plastic provides a biodegradable, lightweight and strong alternative to the oil-based plastics we use today. And in addition to being good for the environment, biodegradable plastic does not contain the chemicals commonly found in other plastics that affect the human body’s endocrine system.

We can now begin producing more modern necessities from hemp.

Until 2018, hemp farming was only legal in small, state-by-state pilot programs. This largely meant that it couldn’t be farmed on an industrial level in the United States, especially when in comparison with large global producers like China.

However, the 2018 Farm Bill officially removed hemp from the Controlled Substances Act. For farmers, this officially makes it a viable crop that they can produce and trade like cotton, soy, and tobacco. But by comparison, the hemp industry is under-developed. We do not have the same harvesting technology, supply chains, accessibility of seeds or research as we have with other, more traditional crops.

Yet the argument for more eco-friendly materials is increasing along with the toll that concrete, plastic, cotton, and fuel are taking on the planet. A world full of hemp alternatives could be in the not-so-distant future.
