Two plastics that are targeted for recycling from household waste are pete (1) ( plastic soft drink bottles/ peanut butter and salad dressing containers) and hdpe (2) ( milk, water, juice containers/ plastic grocery bags). one of the problems of recycling such materials is separating them. suppose you have been hired to set up a process for separating large quantities (many tons) of waste plastic that is a mixture of pete and hdpe. describe how you might perform this separation. any would be much appreciated!
