摘要

Plastic film makes up a relatively small amount of solid waste by mass, but a fairly large amount by volume. The recovery of plastic film waste in the United Kingdom is presently being carried out on a very small scale. Potentially up to 2.5 million tonnes of plastic film is available for recycling from household, commercial and industrial sources, which is the amount currently sent to landfill each year. The main problems facing industrial sectors wishing to recycle plastic films include logistics, processing costs, film separation and contamination. Plastic film recovery from post-consumer waste sources is in its infancy in the UK. Recycling from production sources is a well-established industry. Reprocessors prefer to work with process scrap because it has not been in contact with consumers, therefore there will be virtually no mixing with other non-compatible plastic types or contamination. Persuading the reprocessing industry to work with recovered film from waste sources will involve overcoming a number of technical and waste management issues, as dealt with in this paper. Recycling is heavily reliant on economics - if it is not profitable to collect, sort, clean and reprocess a waste product, the recycling operation will not succeed. This paper highlights and discusses current problems with a view to the recycled film market expanding in the future. Investigated topics include evaluating material recovery options and transport problems, culminating in an economic study to decide the viability of operating a waste plastic film recycling plant. This modelling looked at dependence on material cost, product price, factory throughput and product yield. It was found that the process route is viable but depends on plant capacity, material cost, process yield and product price. Recommendations are made as to the efficiency and throughput of a typical washing and agglomerating plant, in comparison with the prices paid for the waste film product. This work also found that much of the UK waste management infrastructure could possibly be adapted to incorporate plastic film, but investment is needed from the recycling industry to commit to using waste plastic film as a material feedstock, otherwise there will be no demand for the material.
