Abstract Biodegradabilities of polymers and their composites in a controlled compost were described. Effects of sizes and shapes of samples on biodegradability were studied. Introduction Polymers are widely used in various industrial fields due to their merits, such as light weight, resistance to chemicals, resistance to the environment, easy processing, etc. It is difficult for polymers to be treated after use due to their resistance to the environment.

When polymers are disposed of in a natural environment, they remain for a long time without degradation. One of the solutions to this problem of polymers after use is the development of biodegradable polymers.

Biodegradable polymers can be biodegraded eventually by microorganisms in the natural environment into carbon dioxide CO2 and water H2O.

Various types of biodegradable plastics have been developed. Among these biodegradable plastics, polycaprolactone PCL was developed as a biodegradable plastic of the aliphatic polyester type derived from the chemical synthesis of crude petroleum. PCL has good water, oil and chlorine resistance. It has a low melting point ca.

PCL is mainly used in thermoplastic polyurethanes, resins for surface coatings, adhesives and synthetic leather and fabrics. It also serves to make stiffeners for shoes and orthopedic splints, and fully biodegradable compostable bags, sutures, and fibers.

PCL is often mixed with starch to obtain a good biodegradable material in order to reduce its price. Poly lactic acid PLA products have become widely used because of their biodegradability, hydrodegradability and the biorenewable profile with its source as vegetables such as corn.

This allows both the prevention of environmental pollution and the use of renewable resources for a sustainable society. Biorenewable materials are materials made from biomass with absorbed carbon dioxide from the global atmosphere in modern times. The use of biorenewable materials causes a decrease in oil consumption, and the production of the CO2 in the atmosphere from the incineration of such wastes is the same as the CO2 fixed during photosynthesis by plants from the atmosphere nowadays.

In this way, global warming will be reduced. Considering these points, the use of biodegradable and biorenewable materials is expected to be promoted. For increased use of these materials in actual commercial markets, international standards for the evaluation of their biodegradability are very important. Consumers require that products made of biodegradable plastics should display their biodegradability according to international standards.

The Japan Bioplastics Association JBPA is a organization voluntarily founded by the major Japanese plastics producing companies and others focused on plastics, which was established with the aim of promoting the popularization of biodegradable plastics and biomass-based plastics, which play an important role in solving the recycling-technical problems [ 1 ]. JBPA has established two identification systems related to biodegradable plastics products and biomass-based plastics products.
