The liquid waste is applied to the top of the filter and percolates downward, depositing organic matter on the support and the microbial film.
Before the solid waste is ultimately disposed-off, it is processed in order to improve the efficiency of solid waste disposal system and to recover usable resources out of the solid wastes. Until recently however, MRF operators have struggled with glass separation because the only method of processing a glass-inclusive waste stream was by means of the traditional crusher-type technology, and many early MRF installations were set up in such a way that they excluded glass completely from their contracted input feedstock.
The goal was to remove the valuable plastic tops and security rings from residual bottle necks, and thus free the glass up for use in re-melt.
One way that people can help is by sorting their trash into separate categories like glass, paper, and plastics.A way forward for glass recycling The economic and legislative need to recycle ever more materials from the waste stream is the reason for the modern materials recycling facility, but to date they have struggled to recover high quality glass.
