Handbook of Bioplastics and Biocomposites Engineering Applications.
In today & rsquo;s world, bioplastics are becoming increasingly prominent owing mainly to scarcity of oil, increase in the cost of petroleum-based commodities, and growing environmental concerns with the dumping of non-biodegradable plastics in landfills. This book summarizes the field of biopla...
