Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Plastic is being used over the entire globe in the form of capsules,
microbeads, fibers or microplastics. The waste thus generated has gained concern due
to the loss of aesthetic value, the presence of various toxic chemicals such as
plasticizers, antioxidants, etc., and the release of greenhouse gases. The small size and
slow degradability of microplastics are responsible for their accumulation in the
environment and organisms. Plastic degradability can be improved by altering its
chemical and physical structure or using better degrading agents. Different types of
microorganisms and enzymes are being designed and employed for degrading plastic
waste. This chapter gives an overview of the degradation mechanism along with
different microbial, plant and animal species responsible for this process.
