Developing sustainable chain case rubber bush from glove trimmings and rejected gloves in Sri Lanka

Abstract

The global rubber industry is a critical backbone of modern manufacturing, providing indispensable materials for automotive components, industrial machinery, and personal protective equipment [1]. However, the sector faces significant environmental challenges due to the accumulation of rubber waste, particularly in developing nations such as Sri Lanka. A notable contributor to this issue is the disposal of nitrile glove trimmings and rejected gloves generated by the local rubber product manufacturing sector. Traditional disposal methods such as landfilling and incineration not only squander valuable resources but also contribute to long-term environmental degradation. In line with sustainable development goals and the principles of a circular economy, there is growing interest in converting such waste into high-value products. One viable avenue is the fabrication of rubber bushes critical components in automotive and industrial systems that mitigate vibrations, reduce mechanical wear, and enhance durability. This research investigates the feasibility of developing a sustainable chain case rubber bush using mechanically recycled nitrile glove waste. The study employs a systematic methodology involving material collection, mechanical pulverization, advanced rubber compounding, and performance testing. Preliminary findings suggest that the recycled rubber composites demonstrate mechanical properties comparable to conventional products, indicating strong industrial applicability [2]. This innovation promotes eco-efficient manufacturing while addressing Sri Lanka’s pressing rubber waste challenges [3].
