Abstract

A lightweight, highly porous, biodegradable uniaxially or biaxially oriented net, and a method of making same, by stretching a cast integral net of a modified biodegradable polymer such as a corn polymer or a polypropylene polymer having been made biodegradable by use of an additive or other biodegradable resins, and an erosion blanket preferably including a sandwich of a pair of such nets containing an erosion-controlling material such as a quantity of straw, coconut fibers, wood excelsior or the like.
