1, kitchen waste, including food waste such as leftovers, bones, roots, leaves and peels. After in-situ treatment of compost by biotechnology, 0.6-0.7 tons of organic fertilizer can be produced per ton.
2. Other wastes, including bricks and tiles, muck, toilet waste paper, paper towels and other wastes that are difficult to recycle, shells and dust, except for the above-mentioned wastes. Sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air. In fact, great bones are classified as "other rubbish" because they are "hard to corrode". Corn kernels, nut shells, fruit kernels and chicken bones are all kitchen waste.
