Waste paper enters the machine and is compressed by 1 ton. Foreign matter is still on the waste, since people do not bother to wash them off. To keep the temperature of the food, boxes are double-packed with silver foil as well as an ice pack that should have been discarded as landfill waste. If waste paper is discharged mixed with plastic or vinyl, it will cause a problem at the recycling stage. In order to maintain the color of recycled paper or boxes, chemical dyes must be added, and the possibility of adversely affecting the environment increases.
Experts advised that delivery boxes should be discarded after removing the invoice and the vinyl tape, and the paper coated with metal or vinyl such as aluminum must be disposed of separately.
