Abstract

The invention relates to a biodegradable product. The biodegradable product is composed of the following components in parts by weight: 40 to 90 parts of biodegradable resin, 5 to 50 parts of papermaking wastes, 0 to 40 parts of starch, 0 to 5 parts of an inorganic mineral substance and 2 to 15 parts of an auxiliary agent. The invention also relates to a preparation method for the biodegradable product. The biodegradable product provided by the invention has the following advantages: the paper wastes, the starch, the inorganic mineral substance and the biodegradable resin are compounded, so the cost of the biodegradable product is greatly reduced; and the papermaking wastes are effectively utilized, so the pressure on the environment is reduced.
