5.Design for recycling
Sameer Joshi and Sharang Ambadkar
Design for Recycling (DfR) guidelines provide technical criteria to ensure products and packaging can be effectively collected, sorted, and processed into high-quality raw materials at their end-of-life. Core Principles of Design for Recycling Material Selection: Prioritize mono-materials (single polymer types like PE, PP, or PET). Avoid mixing incompatible plastics or using multi-layer films that are difficult to separate. Color Optimization: Transparent or unpigmented materials are highly preferred as they have the highest market value and versatility for reuse. Dark or carbon-black pigments should be avoided as they are often undetectable by infrared sorting machines. Simple Disassembly: Design components like caps, lids, and labels to be easily and completely removable. Use "tear-off" facilities for plastic facings on paper-based products. Label and Adhesive Compatibility: Use labels made of the same material as the main body or water-soluble adhesives that wash off easily during the recycling process.Minimize Contaminants: Avoid additives that alter material density (e.g., glass fibers or heavy fillers) or non-recyclable components like PVC, vulcanized rubber, and complex electronics.
