What Should Do with Different Materials before Composting?

(1) Urban garbage should be sorted, and cullet, stone, tile, plastic and other sundries should be selected; the entry of heavy metals and toxic organic and inorganic substances is especially prevented.
(2) In principle, all kinds of stacked materials should be crushed as well. Increasing the contact area is conducive to decomposing, but it consumes more energy and manpower and is difficult to promote. Generally, it is better to cut various stacked materials into 3-5 cm long.
(3) For materials with high hardness and high wax content, such as corn and sorghum rods, the water absorption is low. It is best to soak the material with sewage or 2% lime water to destroy the wax layer on the straw surface and use water to promote decomposing.
(4) Aquatic weeds, due to excessive water content, should be cooled slightly before stacking.
