Recycling & Waste management of Biopolymers

Biobased biopolymers offer advantages not only on the raw materials side but also on the disposal side through certain promising end-of-life (EOL) options. Especially waste disposal with energy recovery has an added benefit, which lies in gaining carbon neutral energy while allowing multiple uses after possible recycling. The Commission said that all of the composts containing biodegradable polymer materials could be classified using a risk assessment system at a higher toxicity level. Biodegradable biopolymer waste can be treated by aerobic degradation, composting, or anaerobic digestion .When biopolymers are composted or digested, their individual elements are recycled naturally, in particular their carbon and hydrogen content. The largest segment of the market, packaging, is expected to reach nearly 1.7 billion pounds in 2016. The market in 2011 is estimated at 656 million pounds, making the five-year CAGR 20.5%. The second-largest segment, made up of fibers/fabrics, is expected to increase in volume from an estimated 134 million pounds in 2011 to 435 million pounds in 2016, for a five-year CAGR of 26.6%.

There has been a marked increase in interest in biodegradable materials for use in packaging, agriculture, medicine, and other areas. In particular, biodegradable polymer materials (known as biocomposites) are of interest. As a result, many researchers are investing time into modifying traditional materials to make them more userfriendly, and into designing novel polymer composites out of naturally occurring materials. A number of biological materials may be incorporated into biodegradable polymer materials, with the most common being starch and fiber extracted from various types of plants. The belief is that biodegradable polymer materials will reduce the need for synthetic polymer production (thus reducing pollution) at a low cost, thereby producing a positive effect both environmentally and economically.
