The two plastic processing requirements are the level of densification and sorting. Most markets require that plastics be baled and strapped with a non-rust material. The majority of markets prefer not to have the plastic granulated for fear of contamination. Check markets for bail weight requirements. Processed plastics should be stored indoors or covered with an ultraviolet light protector to guard the plastic from the sun s damaging rays.
Most markets require that plastic be sorted by resin type and some also require sorting by color.
Generally, the more carefully that plastics are sorted by color and resin, the move valuable they are. However, this is also influenced by the sorting technology employed. Sorting with x-ray and infrared systems may require less presorting than other programs. Most importantly, provide the market with the good quality, contaminant free material that meets the market specifications. Keep the recycled plastic clean, store it separately and do not allow it to be contaminated.
