“…These polymers are well known for their diverse applications in industries, domestic appliances, transportation, construction, shelters, storage and packaging practices. Such polymers are differentiated according to their chemical nature, structural arrangement, physical properties and applications as shown in Table 1 (Shah et al 2008b;Dey et al 2012;Kumar et al 2011;Smith 2005).…”

Inertness and the indiscriminate use of synthetic polymers leading to increased land and water pollution are of great concern. Plastic is the most useful synthetic polymer, employed in wide range of applications viz. the packaging industries, agriculture, household practices, etc. Unpredicted use of synthetic polymers is leading towards the accumulation of increased solid waste in the natural environment. This affects the natural system and creates various environmental hazards. Plastics are seen as an environmental threat because they are difficult to degrade. This review describes the occurrence and distribution of microbes that are involved in the degradation of both natural and synthetic polymers. Much interest is generated by the degradation of existing plastics using microorganisms. It seems that biological agents and their metabolic enzymes can be exploited as a potent tool for polymer degradation. Bacterial and fungal species are the most abundant biological agents found in nature and have distinct degradation abilities for natural and synthetic polymers.

“…Starch, as one of the cheapest natural polymers, has been comprehensively investigated. [1][2][3] Thermoplastic starch has been produced using conventional thermal extrusion methods at suitable temperatures using added plasticizers (usually water and glycerol), and, in many cases, other polymer additives to modify the properties of starch-based materials. [4][5][6][7][8][9][10][11][12][13] Polymer-clay nanocomposites have attracted a great deal of interest by researchers in academia and industry, because significant improvements in many aspects of material performance can be obtained when using a very low dosing amount of such layered nanoparticles.…”

High-resolution solid-state nuclear magnetic resonance (NMR) was applied as a bulk analysis method to provide an indication of clay dispersion in starch-clay nanocomposites. The starch composite containing 2.5 wt% nano-clay appeared as an exfoliated system with an average distance between clay platelets (oD4) of around 40 nm. Increasing the amount of nano-clay to 5.0 wt% reduced the oD¯4 value to around 20 nm. Aging displayed a minimal effect on the exfoliation of starch-clay nanocomposites. However, the oD¯4 value became much larger on introduction of 5 wt% polyvinyl alcohol (PVOH) into the systems because of the formation of aggregated structures, and the oD¯4 value increased further after aging. The motion of PVOH molecules during the aging period could function as a driving force toward a more stable interaction between PVOH chains and clay platelets, thus resulting in a reduction in the degree of clay exfoliation in the starch matrix.

Abstract-In urban areas, the residential wastes contribute the lions' share of municipal waste. Managing these residential wastes is highly challenging as most of the developing countries do not have a proper waste management plan for their urban areas. The high organic and plastic content and the non segregated form of these wastes make them difficult to handle. Policies and strategies should be framed in such a way that, it must be suitable for the type of wastes generated in the area, nature of generation, characteristic of the area and other factors. This paper presents various policies and strategies for sustainable management of these urban residential wastes through a case study in Kochi city, Kerala, India.
