From above Figures, sold wastes are separated by sellers to increase values of wastes before
selling. For example, aluminum caps are separated out from energy drink bottles which are a
glass. Plastic bottles and their caps are sorted out because they are made from the different
types of plastic materials. Some sellers may cut, wash, and dry milk/juice cartons before
exchange because they can get money from cleaned wastes.
Workers sometimes collect labels, foam, foil, paper, and other which are the wastes from
separation process, and then they sell those wastes to the cement factory for burning as a fuel.
Fruit wastes which are collected from fruit shops are used to produce the cleaning solution.
Food wastes from household are used to feed animals (e.g., pig) and make composting for the
sufficient economic project. Moreover, there are not pretreatment processes in that shop, but
labors only compact wastes by their power to reduce size of wastes and required areas for
waste transportation.
This shop has a board of waste prices in front of the shop, and there are small labels nearby
products to show the prices of products in the shop. Figure C-30 and C-31 show the waste cost
