In the Haidian District, Beijing Changhua Village waste recycling station, the investigators asked that pure polypropylene transparent (PP) lunch box purchase price is 3.2-3.5 yuan / kg; color polypropylene (PP) plastic lunch box is 0.6 yuan / Kg; and polystyrene foam plastic lunch box (foam lunch box) is not recovered. In Beijing Changping District East small village recovery and distribution center and Shanghai, Hangzhou, Guangzhou and other places also do not take such actions as Styrofoam recycling.
A sort of junk cleaner said that the color of the polypropylene (PP) plastic lunch boxes and pure polypropylene transparent lunch boxes, can be 6 kilograms per kilogram and 2 yuan per kilogram of the price sold to the three rounds of waste collection of traders the white foam lunch box no one can only be treated together with the garbage, which will not be sorted out.
International Food Packaging Association executive vice president Dong Jinshi said that on the one hand, one-time foam plastic lunch box use polystyrene resin as raw material, the production process using butane blowing agent, so that the foam lunch box itself with a large volume and low density, light weight and other characteristics, resulting in high foam bag transport and storage costs, such as a load of 3 tons of 130 trucks can only load more than 200 kilograms of foam lunch box, which take up a large space.
On the other hand, after the use of foam bags, they are extremely difficult to clean, and after cleaning the oil waste water is difficult to deal with, which is easy to cause pollution. In addition, after the recovery of the EPS boxes, the polystyrene particles are only used for the production of low-end plastic products or ordinary building materials such as insulation boards, the profit is very low. However, INTCO recycling has different kinds of machines to deal with EPS, such as EPS compactor. This machine can compact the EPS into blocks with the ratio of 50:1, which is easy to transport and is a good helper to take such action as Styrofoam recycling.
