Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc. Metal: mainly includes cans, canned goods, toothpaste wrappers, etc. Fabric: mainly includes discarded clothes. Tablecloths, face towels, backpacks, shoes, and so on. Through comprehensive processing and recycling, pollution can be reduced and resources can be saved. For example, for every ton of recycled paper, 850 kilograms of paper can be made, saving 300 kilograms of wood and reducing pollution by 74% compared to the same mass production; For every 1 ton of plastic beverage bottles recycled, 0.7 tons of secondary raw materials can be obtained; Every ton of scrap steel recycled can produce 0.9 tons of steel, saving 47% of costs compared to ore smelting, 75% of air pollution, and 97% of water pollution and solid waste.

2. Kitchen waste: including leftover food such as bones, vegetable roots, leaves, fruit peels, etc., which can be processed and composted on-site through biotechnology to produce 0.3 tons of organic fertilizer per ton.
