摘要
The use of plastics in agriculture and in fisheries has been vital to increase food production and meet the demands of an increasingly growing global population. However, there are several drawbacks to the use of plastics in these industries. Most plastics used in agriculture are disposed of after one single use and are highly susceptible to weathering. Abandoned, lost, or discarded fishing gear cause considerable damage to marine life. Quantification of plastic waste generation in these industries is scarce or non-existent in the case of fisheries. In this paper, we estimate the amount of plastic waste generated by agriculture and fisheries at a regional scale, considering the South West of the UK as a case study. We followed a mass balance approach to quantify the potential plastic waste generated by these industries. We find a generation of 49 kt of plastic waste in agriculture, 47% of which has an unknown fate. We estimate 454 t/year of fishing gear waste, with unclear end-of-life pathways. A detailed quantitative understanding of plastic waste generation per sector at a regional scale is fundamental for tracking plastic waste flows, locating hotspots of pollution, and planning actions to reduce the amount of plastic waste along the chain of end-users.
