Biodegradation of aliphatic polyesters,utdoor conditions. Work has been in progress for the last two decades which has led to their applications in surgery and in pharmacology. Basically, these compounds are also of interest for outdoor applications such as packagings or mulch films and in plant therapy by controlled delivery of pesticid

These characteristics have excited a renewed interest in starch-based plastics, as testified by an impressive literature in recent years..This chapter reviews the main results obtained in the fields of starch-filled plastics and thermoplastic starch, paying particular attention to the co

Ethylene-carbon monoxide copolymers, control plastic litter caused by polyethylene loop carriers for beverage cans which have been reported to entangle and endanger wildlife..The rate of photodegradation of E/CO polymers depends on the amount of CO incorporated. At 1% CO, E/CO took about six days to reach zero elongation at break in T

Photo-biodegradable plastics,l. Essential requirements are that the degradation process should be controllable and that it should lead to lower molar mass oxidation products which can be assimilated by microorganisms to give biomass and ultimately carbon dioxide and water. It is shown that certain types of antioxidant, notably

The role of degradable polymers in agricultural systems,.The introduction of photo-biodegradable plastic films substantially prevents the problems commonly arising from the use of other, non-speciality plastic products, thus extending the agricultural benefits and environmental compatibility of this technique in mechanical harvesting of herbaceous crops.

Degradable polymers in waste and litter control,, as advocated by some environmentalists, is considered to be unrealistic. The main advantages of plastics is their lightness and resistance to water and water-borne microorganisms. However, these advantages in use are the main reasons for their obtrusive nature on the sea shore and in the countrysi

The end products of thermal and photooxidation are low molecular weight carboxylic acids which are involved in the eventual bioassimilation of the polymers in the ecosystem..Antioxidan
