The [[Food Waste]]is either collected separately or with [[Green Waste]] and is delivered to an enclosed reception area. Any contamination such as plastic bags, bits of metal etc are removed and the remaining material is shredded to a uniform size and consistency ([[Green Waste]] may be added to ensure the mixture has a structure to allow air to pass through the material during the treatment process). From there it is loaded into a first ‘barrier’ which will be a bay/tunnel etc depending on the system used.  All the material delivered to a facility, plus the first barrier stage, is considered a ‘dirty area’ under [[ABPR]]. The regulations ensure that strict procedures are in place to prevent cross-contamination of ‘clean areas’ (where product is processed and stored) from ‘dirty areas’.

The composting process is kick-started by naturally occurring micro-organisms already in the waste. They break down the material, releasing the nutrients and in doing so they increase the temperature to the 60-70ºC needed to kill pathogens and weed seeds, and meet the regulations for processing [[Animal By-product Material]].
