Waste Plastic Recycling

As the production volume of polymers increases, so does the amount of plastic waste. Plastic recycling is one of the concepts to address in this issue. Unfortunately, only a small fraction of plastic waste is recycled. Even with the development of polymers for closed loop recycling that can be in theory reprocessed infinitely the inherent dilemma is that because of collection, cleaning and separation processes the obtained materials simply are not cost competitive with virgin materials. Chemical upcycling, the conversion of polymers to higher valuable products, either polymeric or monomeric, could mitigate this issue. In the following article, we highlight recent examples in this young but fast-growing field. This article is part of the theme issue 'Bio-derived and bioinspired sustainable advanced materials for emerging technologies (part 2)'.

Mulching Film

The overuse of plastic mulching film in Awat county caused a gradual process of deterioration of the local soil environment, greatly polluted the environmental sanitation in rural areas and hindered the improvement of agricultural machinery's operation quality. After analyzing the related data of plastic mulching film use, and the status of its' recovery and utilization in Awat county, presented the optimizing countermeasures from the following aspects: strengthening the propaganda of the harmfulness of “white pollution”, promoting local peasants' ecological civilization consciousness; developing waste plastic recycling enterprises, broadening the recycling channels; formulating preferential policies to increase the support for waste plastic recycling; controlling and reducing the plastic mulching film residuals from farming techniques; intensifying residual plastic recycling by combining manual and mechanical recycling.
