Reviving the Single-Use Cup Every year, billions of paper coffee cups end up in landfills. This guide details the industrial process used to create Extract, a premium paper line that gives these discarded items a second life. You will learn the mechanical and chemical steps required to separate stubborn plastic linings from high-quality wood fibers, resulting in a sustainable medium suitable for high-end publications like Cherry Bones. Required Materials and Specialized Infrastructure To replicate this process at scale, you need a specialized paper mill capable of "CupCycling." The primary raw material consists of used coffee cups sourced through dedicated recycling schemes like those operated by Costa Coffee or McDonald's. You also need a supply of water, a blending chest (industrial cauldron), and a modern printing press for the final output. The Step-by-Step Recovery Process 1. **Sourcing and Sorting**: Collect cups via dedicated bins. Standard recycling streams fail because they cannot handle the polyethylene lining. 2. **Pulp Quality Testing**: Analyze the cup composition. Aim for a ratio of 95% chemical pulp to 5% mechanical pulp. High chemical pulp content ensures the final paper is durable and versatile. 3. **The Secret Separation**: Submerge the cups in the "secret sauce" separation tank. This process strips the inner plastic layer from the paper without damaging the fibers. 4. **Plastic Upcycling**: Divert the separated plastic waste to manufacturers who can turn it into long-term goods like garden furniture. 5. **The Blending Chest**: Combine the recovered paper slurry with water and heat in a large cauldron. Add pigments at this stage if you desire specific colors. 6. **De-watering and Drying**: Run the pulp through a wire press to reduce water content from 99% to 50%. Pass it through heated rollers until moisture levels hit a precise 7%. 7. **Quality Control and Rolling**: Use automated sensors to check thickness before winding the finished sheet onto a jumbo roll. Troubleshooting Fiber Integrity If the resulting paper feels brittle or weak, check your mechanical pulp levels. Too much mechanical pulp—where wood is ground rather than chemically treated—shortens the fibers and reduces the paper's lifespan. Always verify the source material before processing to ensure it meets the 95% chemical pulp threshold. The Sustainable Result Following these steps produces a tactile, high-detail paper that honors the circular economy. By utilizing this method, GF Smith and James Cropper prove that even "un-recyclable" waste can become the foundation for beautiful, ad-free journalism.
