The Growing Potential of Hemp Bioplastics in a Sustainable World

In the quest for more sustainable and environmentally friendly alternatives to traditional plastics, hemp bioplastics are emerging as a promising solution. Hemp bioplastics are a natural and affordable substitute for oil-based plastics, offering various advantages over their synthetic counterparts. Companies like Polymec S.L., in collaboration with Global BioSolutions Group (GBSG), are at the forefront of research and development in this field, paving the way for a greener future.


Polymec S.L. and Global BioSolutions Group (GBSG): A Synergistic Partnership

Polymec, SL, a Spanish company with over 40 years of experience, has established itself as a manufacturer of high-quality polyester profiles reinforced with fiberglass and carbon using the pultrusion system. They prioritize the use of the best materials available, resulting in superior products like graphene profiles, carbon fiber profiles, and fiberglass corrugation.


In 2021, Polymec S.L. joined forces with Colombia Hemp International S.A., a subsidiary of the Global BioSolutions Group, LLC. Their collaboration focuses on researching and developing bioplastics using hemp fiber. After conducting prototype trials in the latter half of 2022, with promising preliminary results, they are expanding their efforts in 2023 to include bio-composites using recycled resins and biodegradable hemp fiber. Additionally, the team is exploring the use of hemp-based 3D-printed construction materials within the GREENMUR Project led by Nehemiah Group, marking Polymec's leadership in Europe.


This partnership opens immediate opportunities in the EU, USA, and soon in Asia markets, offering biodegradable composites and building materials that the industry increasingly demands.


Understanding Hemp Bioplastics

Hemp bioplastic is a sustainable alternative to oil-based plastics, derived from the stalk of the hemp plant. Hemp's cellulose content, ranging from 65% to 70%, surpasses that of wood (40%), making it an excellent candidate for producing durable and strong bioplastics. Studies show that hemp bioplastics are five times stiffer and 2.5 times stronger than polypropylene, a common plastic material. Furthermore, hemp is lightweight, making it suitable for various applications, including construction, packaging, and transportation.


One of the key advantages of hemp bioplastics is their biodegradability. Hemp bioplastics decompose within 3 to 6 months without releasing harmful CO2 emissions. GBSG has developed natural microbiologic enzymes and proteins combined with bacteria that control the decomposing time. This is applicable specifically to bio composites which require a shelf life of an extended period of time. Hemp cultivation requires minimal water, fertilizers, and pesticides, and it can even be employed for soil remediation, making it a sustainable choice.


The Market for Hemp Bioplastics

The global hemp bioplastic market has been growing steadily, gaining traction due to increasing awareness of environmental issues and government restrictions on traditional plastics. In 2021, the market was valued at approximately $83.5 million, but the potential for growth is immense.


The total bioplastic market was valued at $5 billion in 2020, with a strong shift towards bioplastics from traditional plastics. Europe's biodegradable, plant-based plastic market was worth $0.8 billion in 2019, and it's expected to reach $1.9 billion by 2027. Simultaneously, the global industrial hemp market reached $3.61 billion in 2020.


With a compound annual growth rate (CAGR) of 13.6%, the global hemp bioplastic market is projected to reach $290.7 million by 2031. While the industry is poised for growth, it does face certain challenges.





Challenges and Opportunities

Hemp bioplastics are still in their early stages, and their production is relatively expensive. Competing with subsidized alternatives like corn and soy bioplastics can be challenging in terms of cost. The production process, which involves decortication and fiber treatment, requires significant investments in machinery and time.


Moreover, the legal status of hemp varies by country, which adds another layer of complexity to the industry. However, as hemp gains more legal acceptance and attention, production processes are expected to improve, leading to more cost-effective supply chains and increased adoption.



The Road Ahead

The potential of hemp bioplastics is undeniable, and with sustained efforts from companies like Polymec S.L. and GBSG, this eco-friendly alternative is poised to make a significant impact. While it may not completely replace traditional plastics, the growing demand for sustainable materials and the relaxation of hemp bans make the future of hemp bioplastics promising.


As consumer awareness continues to rise, and governments implement stricter regulations on traditional plastics, the hemp bioplastic market is set for substantial growth. In a world striving for sustainability, hemp bioplastics represent a pivotal step toward reducing our reliance on environmentally harmful materials.
