Recycling Hemp & Cannabis Bio-Waste


In a world of increasing pollution, two startups are trailblazing new techniques to reduce waste by recycling hemp.

The community based around hemp is famous for its holistic approach to life. Hemp advocates care about living cleanly, reducing their environmental impact, and trying to reduce waste as much as possible.

Industrial hemp is now fully legal in the United States thanks to the 2018 Farm Bill. As a result, we can expect the hemp industry to grow and produce more waste. Companies like 9Fiber and Kindness 3D see this as an opportunity.

Previously, we reported on Sana Packaging, who use hemp to create sustainable packaging for the recreational cannabis industry. 9Fiber and Kindness 3D differ in that they’re recycling hemp and cannabis waste after it’s produced. They’re helping reduce pollution and helping their fellow human beings at the same time.


9Fiber, based out of Silver Spring, Maryland are an agricultural technology company focused on recycling hemp stalk and stem waste. This startup takes hemp bio-waste that’s been put aside by other companies and processes it into raw materials that can be used to make a variety of products.

First, 9Fiber decontaminates any biowaste from federally illegal substances, removing the THC. Next, they process the waste further by removing fiber from the hurd, which is the woody core of the hemp plant. Then, the fiber undergoes final processing before it becomes usable for production. With the recycled fiber and gum-free hurd, 9Fiber is able to make paper, rope, textiles, fuel, bioplastics, fiberglass, hempcrete, and even livestock bedding.

In November, the Colorado Advanced Industries Accelerator Grant Program gave 9Fiber a $250,000 grant. The process to get the grant was a lengthy one, as many startups. With this new funding, 9Fiber plans to expand their operations into Pueblo, Colorado in late 2019. Hopefully, this grant can also help 9Fiber scale with the inevitable boom in hemp production. With the recent passing of the 2018 Farm Bill, 9Fiber’s future is looking bright.

9Fiber is recycling hemp by separating out the hemp fibers and woody core (hemp hurd). After processing, 9Fiber can reuse these materials in hemp plastic, hempcrete, animal bedding and more.

Adin Alai, 9Fiber’s CEO, told us, “our main goal is to create an entire circular economy.”

While the hemp industry inevitably produces waste, companies like 9Fiber can use that waste to produce other products. Not only is Mr. Alai passionate about his startup, but he believes that the cannabis industry has the potential to be a leading zero-waste industry.


Meanwhile, up north in Nova Scotia, Canada, a prosthetic limb production company recycles plastic waste from local psychoactive cannabis (“marijuana”) shops. After Canada legalized recreational use of marijuana, there has been a dramatic increase in plastic container waste. Based out of Halifax, Kindness 3D turns plastic packaging from psychoactive cannabis products into prosthetic limbs.

Starting as a 3D printing enthusiast, Jake Boudreau started Kindness 3D after coming across templates for prosthetic limbs in an online 3D printing community. Since the creation of the non-profit, he’s been able to send hands to a girl in Costa Rica and a woman in Brazil. He aims to not only recycle reusable plastic waste, but to help people who can’t afford the expenses that come along with prosthetic limbs.

As industrial hemp and cannabis legalization spreads around the world, companies like 9Fiber and Kindness 3D fill an important niche. Efforts like these are vital for reducing hemp waste, and to increase the utility of the hemp plant. Hopefully, recycling hemp will become commonplace, and recycled hemp biomass products can become part of our everyday lives.

Hemp’s future is green, in more ways than one.
