Abstract text


A method for making a plant-cultivating web from excretive sludge of domestic animals includes collecting sludge; concentrating the sludge; stabilizing the sludge; dehydrating the sludge; mixing the sludge with polyvinyl acetate (PVAC), wherein the mixing ratio between the sludge and PVAC is 4:1; drying a mixture of the sludge and PVAC; grinding the dried mixture into powders; mixing the powders with polyethylene, wherein the mixing ratio between the powders and polyethylene is 10%-80%:90%-10%; adding high molecular weight starch into a mixture of the powders and polyethylene; and rolling the starch/mixture of the powders and polyethylene into a plate-cultivating web. An environment-protective and waste-reusing product is provided accordingly.
