Waste management environmentally degradable

In the context of plastics waste management, environmentally degradable polymers should also be mentioned [67]. As a complete solution to the waste management problem they were perhaps overpromoted at first. Unsatisfied expectations and unproved claims on degradability have created serious scepticism towards these materials [68]. 

These environmentally degradable polyolefins, because of their cost/ performance profiles are very competitive for the growing markets for such plastics. They will be strong competition for the polyester types such as poly(lactic acid) and polyhydroxyalkanoates so frequently publicized as the innovative solution to plastic waste management.

Part III comprises a thorough description of the roles of clays in environmental protection and degradation. The environmental impacts of clay mining, beneficiation and clay-related industries and the natural processes by which clays protect the environment are explained in the initial chapters of Part III. The next chapters introduce the application of clays and their derivatives to resist pollution, recycling of industrial waste products and waste managements (for both toxic and non-toxic wastes). 

The growing environmental awareness and new rules and regulations, as well as new trends in solid waste management, have led scientists to increase activities on the design of compostable polymer materials that easify degrade under well-defined environmental conditions.
