Waste management degradation environment

Why should microbes produce waste Many microbes, like plants, have considerable control over their intake of simple substances. Although many microbes do use complex molecules as a source of necessary elements, microbes commonly excrete degradative enzymes that breakdown the complex molecules into simpler substances, substances that can be taken up by the microbe in a controlled way. A characteristic of many microbes is their ability to alter their immediate environment and that includes their chemical environment. However, because of the diversity of microbes and their remarkably versatile biochemistry, one can never dismiss the possibility that some NPs made by microbes could serve a minor role in waste management .

Litter Problem Plastics waste in urban litter does pose a serious and real waste management problem. Unlike paper, plastics do not degrade in the outdoor environment at a fast enough rate compared to that of littering. The result is a serious aesthetic problem in highly populated urban areas in almost any part of... 

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). 

Solid waste is defined as discarded material which is no longer used in its present form or condition however, it is a resource which is potentially useful. In reality, certain types of waste may render recovery and reuse impractical, inadvisable or even unfeasible. Solid waste management reduces the negative impact that non-degradable plastics waste could have on the environment. 

Since plastics can comprise up to 40% bulk of all the waste in landfill, another waste management strategy is to speed up their chemical breakdown once they enter the waste stream [5]. This is not recycling, simply an attempt to limit environmental damage. Plastic litter that is dropped will thereby harmlessly degrade in the natural environment. It makes good sense. 

A range of degradable plastics provides potential solutions to the problems of domestic and industrial litter disposal in different environments. In the same way, a hierarchy of complementary conservation and disposal techniques are required to solve the escalating problem of waste management in industrial societies.
