In Woburn, Massachusetts, a team in a local lab is working on transforming tiny bioplastic pellets into everyday items like forks and films that won’t contribute to long-lasting microplastic pollution. These pellets are part of an effort by CJ Biomaterials, which uses sugar fermentation to create plant-based polymers that microbes can consume. This approach offers an alternative to traditional fossil fuel-based plastics and is considered a potential solution to the problem of global plastic pollution.
At the Woburn research facility, technicians are testing the creation of different products from these pellets. For instance, they recently used a molding machine to fashion thin forks suitable for home composting, though they are not robust enough to handle heavier foods like steak. Different batch tests have produced more rigid utensils, resembling typical plastic forks. Additionally, the pellets have been melted into films, which could serve as strong food packaging, although they lack the elasticity of traditional cling wrap.
“Plastics have remained largely unchanged,” remarked Leah Ford, the company’s marketing director. “But with growing concerns about microplastics, we’re seeing increased interest in alternatives like bioplastics.”
Traditional plastics can fragment into harmful microplastics over time, found widely in oceans, air, and even within the human body. The use of bioplastics could reduce such issues by breaking down more naturally. For example, products like compostable straws and utensils made from these materials biodegrade fully, reducing landfill waste and methane emissions from food waste.
The lab showcases various successes, including compostable cutlery and food packaging. Employees at the facility use these products daily, reinforcing their practicality in real-world settings. The facility’s advancements include creating PHA polymers that combine renewability with biodegradability.
CJ Biomaterials, a branch of the South Korean CJ Group, produces PHA in Indonesia and supplies these materials globally. The use of PHA helps reduce reliance on fossil fuels—beneficial for the climate and part of a broader movement towards sustainable solutions.
The exploration for effective replacements for conventional plastics continues. While bioplastics provide one option, more research on their environmental impact is essential. Critics argue that bioplastics may distract from more comprehensive solutions and raise concerns about using agricultural land for non-food crops.
Despite this, the adoption of bioplastics is slowly rising, representing about 0.5% of annual plastic production worldwide. Production is expected to double by 2030 due to increasing demand. Notable organizations like McDonald’s and major sports venues are trialing these materials in their operations.
Challenges to bioplastic adoption include higher costs compared to traditional plastics and limited composting facilities. Many facilities do not accept bioplastics, fearing impact on soil quality. Initiatives like Black Earth Compost are working to change this perception, integrating compostable products with organic waste.
The 5 Gyres Institute evaluated various materials, including bioplastics, in natural environments across the U.S. By the study’s end, biodegradable items significantly decomposed, unlike their fossil-based counterparts that persisted. This finding highlights the need for biodegradable options over traditional plastics, as emphasized by the institute’s co-founder, Marcus Eriksen.
