Used rest room paper and paper towels are dry rubbish. Toilet paper, rest room paper, etc. will dissolve in water and aren't taken into consideration as recyclable "paper", just like cigarette cases. All types of waste paper, along with newspapers, periodicals, books, diverse packaging papers, etc. belong to recyclable paper.

Other rubbish (called dry rubbish in Shanghai) consists of bricks, ceramics, muck, rest room waste paper, paper towels and different wastes which are hard to recycle, dust, and meals bags (boxes) aside from the above-stated sorts of rubbish. Adopting sanitary landfill can correctly lessen the pollutants of groundwater, floor water, soil and air.
