Final answer:
The composition of the recycle stream for effective recycling depends on the use and form of the waste. Different waste compositions exist in different municipalities and according to the level of recycling activity. It is important for residents to be informed about which waste can be recycled and which should be disposed of as ordinary trash.
Step-by-step explanation:
In order for recycling to be effective, the composition of the recycle stream must meet certain criteria. First, the waste must be unused and in the form of a commercial chemical product. This means that chemicals that have already been used or are not in a commercial form are not suitable for recycling.
Additionally, not all categories of waste are accepted by all local recycling authorities. It is important for residents to be informed about which types of waste should be placed in recycling containers and which should be disposed of as ordinary trash. Different municipalities have different waste compositions.
In developed areas with significant recycling activity, the waste stream mainly consists of intractable wastes such as plastic film and non-recyclable packaging materials. However, in areas without much recycling, the waste composition includes food wastes, market wastes, yard wastes, plastic containers, product packaging materials, and other miscellaneous solid wastes.
