Halting climate change represents the most significant challenge facing humanity in the current century. With the escalating challenges caused by global warming, reducing greenhouse gas emissions through effective recycling strategies for plastic components has become imperative. Besides the large plastic waste producers, niche products also offer significant opportunities for reducing greenhouse gas emissions and conserving resources. This research provides an overview of the recycling techniques and explores the potential of recycling niche products exemplarily focussing on old climbing ropes and agricultural binding twines. Climbing ropes made from polyamide 6 (PA6) were successfully recycled into granulate, exhibiting superior tensile strength and elastic modulus compared to the reference virgin PA6. Similarly, agricultural binding twines made from polypropylene (PP) were recycled, with detailed analysis revealing mechanical and rheological properties degradation over multiple cycles. The findings highlight the hidden potential of niche product recycling.
