Abstract

Plastics are extensively used in every facet of our lives. But at the same time, petroleum-based plastics have hazardous effect on the environment. Bioplastics, made from biological materials represent an effective solution to this problem. Starch based bioplastics account for the major portion of the bioplastic market. In the manufacture of starch-based thermoplastics, plasticizers are added to the polymer matrix to enhance its flexibility. This study examined the effect of glycerol as plasticizer on the mechanical and moisture absorption properties of starch-based bioplastics. Varying amount of glycerol was used to produce bioplastics and then their tensile strength, density and moisture content were determined. It was observed that, there is a decreasing trend in tensile strength and moisture content with increase in the amount of glycerol, whereas, this trend gets inverted in case of density.

Keywords

Abstract

Unfortunately, there are globally various examples of poor wastewater planning and management of poorly targeted government investments that targeted low priority problems ineffectively. Integrated wastewater management is essential for responsible use of the environment and affordable provision of services within an overall water resources management system. About 7.5 % of all deaths in India are due to deficiencies in safety of water sanitation or hygiene. The effective use of treated effluent for gardening, industries can save the potable water which can be sufficiently utilised in draughts in States like Rajasthan where underground water is the main source of water supply. During present work, a study has been undertaken for integrated wastewater management system for Jaipur city. The city has sufficient sewage treatment plants (STPs) to meet the wastewater generated. An attempt has been made through this article to understand the present available system to handle the water scarcity issues effectively and to suggest that no sustainable solution is likely to come up until an integrated approach including socio-political reasons behind wastewater pollution is achieved.

Keywords

Integrated Wastewater, Management, Jaipur City, Sewage Treatment Plants.

Abstract

India has currently about 4291 large dams having a height above 10 metres. The construction of dams is often associated with several implications associated with environment, which can be categorized broadly as due to existence of dams and due to pattern of dam operation. Besides, the dams also change climate and have great social and economic implications. The paper highlights all such major problems associated with dams.
