A Sustainable Approach
At MIT Waste Management Company, environmental sustainability is at the heart of everything we do. One of our standout initiatives involves tackling the challenges of Tetra Pak recycling, a packaging material widely used for milk, juice, and other liquid foods. Despite the complexities posed by their multi-layered composition, we have developed innovative solutions to recycle these materials effectively.
Post-Consumer Tetra Pak Collection
Our recycling journey begins with the efficient collection of post-consumer Tetra Pak materials. We collaborate with local communities, waste management partners, and consumers to ensure these materials are diverted from landfills, contributing to a significant reduction in waste.
Transforming Tetra Paks into Reusable Resources
Tetra Pak containers consist of high-quality paper fibers (75%), polyethylene (20%), and aluminum (5%). Our specialized recycling process separates these components:
- Paper Fibers: The fibers are extracted and repurposed into pulp, which is then utilized in manufacturing new paper products, fostering a circular economy within the paper industry.
- Polyethylene and Aluminum (Poly-Al): The remaining material is processed and repurposed into valuable products, showcasing our commitment to innovation and sustainability.
Poly-Al Material: From Waste to Practical Applications
The Poly-Al material obtained from Tetra Paks is transformed into a variety of functional products, including roofing sheets and pallets. These innovations highlight the versatility and reusability of recycled materials.
Steps in the Poly-Al Conversion Process:
- Collection and Sorting: Poly-Al waste, primarily sourced from beverage cartons, is collected and sorted to ensure the purity and quality of the material.
- Shredding and Cleaning: The sorted material is shredded into smaller pieces and thoroughly cleaned to remove organic residues.
- Extrusion and Formation: The cleaned Poly-Al is melted and molded into desired forms:
- For roofing sheets, the material is passed through flat die extrusion, cooled, and cut into sheets of required sizes.
- For pallets, the molten Poly-Al is molded using injection or compression techniques.
- Finishing and Quality Control: The final products are treated for durability and UV resistance, ensuring they meet industry standards.
The Impact of Tetra Pak Recycling
Through our recycling efforts, we:
- Significantly reduce landfill waste.
- Conserve vital natural resources.
- Minimize greenhouse gas emissions, promoting a healthier environment.
Our work in Tetra Pak recycling is a testament to our dedication to sustainable practices and advancing recycling technologies. By converting waste into valuable products like roofing sheets and pallets, we continue to make strides toward a cleaner and more sustainable future.
