Decoding Compostable Plastics: A Call for Clarity in Lab Waste Management
Understanding the Challenges of Compostable Plastics in Recycling Streams
In the pursuit of sustainability, many laboratories have adopted compostable plastics, believing them to be an eco-friendly alternative to traditional plastics. However, as environmental engineering educator Ali Ling highlighted in a recent LinkedIn post, integrating compostable plastics into recycling systems can lead to significant contamination issues.
At Boston Children's Hospital (BCH), our Green Labs program, in collaboration with the E.A.R.T.H. Environmental Sustainability Employee-Led Group, is committed to promoting sustainable practices within our research community. This commitment is critical to ensuring our waste management protocols are effective and environmentally responsible.
The Misconception of Compostable Plastics
Compostable plastics are designed to break down under specific composting conditions, which are not typically found in standard recycling facilities. When these materials are mistakenly placed in recycling bins, they can contaminate recyclable streams, rejecting entire batches of recyclables. This undermines recycling efforts and increases the volume of waste directed to landfills.
The Role of Clear Labeling and Education
A significant contributor to this issue is the confusion surrounding labeling. A triangular symbol on compostable plastics often leads individuals to believe these items are recyclable. However, this symbol merely indicates the type of plastic resin used and does not guarantee recyclability.
To address this, BCH Green Labs and E.A.R.T.H. ELG are focusing on educational initiatives that clarify the distinctions between recyclable and compostable materials. By providing clear guidelines and resources, we aim to empower our research community to make informed decisions about waste disposal.
Action Steps for the BCH Research Community
Review Waste Disposal Protocols: Familiarize yourself with BCH's waste management guidelines to ensure proper sorting of compostable and recyclable materials.
Participate in Training Sessions: Engage in workshops and seminars offered by BCH Green Labs and E.A.R.T.H. ELG to stay updated on best practices in sustainable lab operations.
Provide Feedback: Share your experiences and suggestions with our sustainability teams to help us continuously improve our waste management strategies.
Conclusion
While compostable plastics offer potential environmental benefits, improper disposal can negate these advantages. Through education, clear labeling, and community engagement, BCH Green Labs and E.A.R.T.H. ELG are dedicated to fostering a culture of sustainability that extends to every aspect of our research operations.
