Question

For 2012, rank the type of materials in the waste stream to the percentage of municipal solid waste they compromise, by weight before recycling. Rank from 1 (highest percentage) to 5 (lowest percentage).

Answer 1

The ranking of materials in the municipal solid waste stream, by weight before recycling, for 2012 is as follows: 1) Food residue, 2) Non-combustibles, 3) Paper, 4) Plastics, and 5) Textiles.

Step-by-step explanation:

1. Food residue
2. Non-combustibles
3. Paper
4. Plastics
5. Textiles

The composition of municipal solid waste varies from place to place, but in general, the ranking of materials in the waste stream, by weight before recycling, for 2012 is as follows: 1) Food residue, 2) Non-combustibles, 3) Paper, 4) Plastics, and 5) Textiles. This ranking is based on the percentages of each material found in the waste stream. For example, in China in 2012, food residue accounted for 55.9% of municipal solid waste, non-combustibles accounted for 18.4%, paper accounted for 8.5%, plastics accounted for 11.2%, and textiles accounted for 3.2% (source: Figure 12.4.1).

Answer 2

Food 5

Plastic 1

Step-by-step explanation:

behaviors of people as well as the rapid advances of technology, amounts and the composition of MSW have been also changed. In a study carried out by the European Environmental Agency to study the per capita annual MSW produced by 32 European countries during 2001–2010, they found that this waste increased in 21 countries, and was decreased in 11 countries. The study also studied the amount of wastes of 26 countries between 2001 and 2008; they found that these amounts decreased in 6 countries. Thus, the amounts and characteristics of the wastes varied from country to another country, as well as from region to region even within the same city according the mentioned factors including the usage habits of people
