For example, global firms like TerraCycle offer PPE recycling boxes that make environmentally conscious PPE disposal more accessible for businesses and communities.
2. Chemical Recycling: Turning PPE into Energy
Chemical recycling techniques such as pyrolysis and gasification can convert used polypropylene masks and gowns into fuel, chemicals, or new plastics. These solutions provide a circular approach, turning waste into raw material rather than landfill fodder. While still an emerging technology, several pilot projects worldwide demonstrate its feasibility and scalability for medical PPE recycling.
3. Upcycling PPE Waste into Useful Products
Upcycling goes a step further by transforming discarded PPE into innovative products:
- Eco-Bricks: Used masks and gloves are compacted with other plastics to create building blocks for low-cost housing.
