Section II: A Word About Mold Making and Casting Mold Making and Casting are not entirely exact sciences.
Making the world better, one answer at a time. Polypropylene can be biodegradable if it is made with EBD (enhanced bio decompositions) which can be easily broken down, fairly quickly, back to base compounds.A variety of packaging can now use biodegradable polypropylene.   Natural materials are by definition biodegradable. That means that cotton, wool, linen and silk fulfill this criterion. Cotton and linen are cellulose based (a pol â¦ ysaccharide) while wool and silk are made of protein types)wool is made of keratin as is human hair).
