2.1 BIODEGRADABLE COMPOSITIONS OF STARCH
2.1.1 INTRODUCTION
Because of constantly increasing production of polymers leading to environmental pollution, the problem of their utilization is becoming more and more urgent. This problem can be solved by creation of biodegradable polymer materials which can be decomposed under the environmental conditions to give harmless products for nature (H2O, CO2, biomass, and other natural compounds). Despite the fact that the cost of biodegradable polymers is higher than the cost of traditional synthetic polymers, they intensively lock in the consumer markets. The rise in application of biodegradable materials is primarily connected with irreplaceable consumption of the world reserves of oil products representing main raw material for production of synthetic polymers. With increase of production capacities of biodegradable polymer compositions and improvement of their production technology, their cost will gradually decrease and approach the cost of traditional synthetic polymers.
