Plastics are a ubiquitous part of modern life. They can be modified to meet the demands of almost any conceivable application1. While plastic is extremely useful and has been very important in the development of society since the beginning of the 20th century, it also presents a problem. It is estimated that 25 Mt of plastic waste was generated in the European Union in 2008. As much as 49 % of ...

As the rate of consumption of plastic materials in the world is greatly expanded, more waste plastics are generated. In recent years, their generation amount in Korea becomes about four million tons per year, according to data from the National Institute of Environmental Research. The disposal of waste plastic is mostly achieved by conventional ways such as landfill or incineration. However, th...

Oceans are a major source of biodiversity, they provide livelihood, and regulate the global ecosystem by absorbing heat and CO2 . However, they are highly polluted with plastic waste. We are discussing here microbial biotechnology advances with the view to improve the start and the end of life of biodegradable polymers, which could contribute to the sustainable use of marine and coastal ecosyst...

the main objective of this investigation was to achieve a clear pattern of solid waste collection and disposal in selected hospital and health care establishments in certain cities of tehran province. this study was done in more than 82 percent of all hospitals with 3017 beds during the year 1996. solid waste produced per bed was evaluated to be 2.87 kg per day which was 8670 kg per day, for al...

Plastics have outgrown most man-made materials and have long been under environmental scrutiny. However, robust global information, particularly about their end-of-life fate, is lacking. By identifying and synthesizing dispersed data on production, use, and end-of-life management of polymer resins, synthetic fibers, and additives, we present the first global analysis of all mass-produced plasti...

H. F. Wang, J. J. Lu, K. F. Chen, H. L. Duan, Wuhan Textile University, Wuhan, China A new method to treat four solid wastes of sodium silicate used sands, dewatered municipal sludge, clay sands sludge and waste polyethylene, was discussed. About wt/ 50 % sodium silicate used sands and wt/ 50 % dewatered sludge were mixed, and then cured by microwave with a certain thickness film of clay sands ...

Petroleum-based plastics have many drawbacks: the large amount of energy required to produce the plastic, the waste generated as a result of plastic production, and the accumulation of waste due to slow degradation rate. It is because of these negative attributes of conventional plastic use that attention is being focused on environmentally friendly plastics from alternative sources. Albumin pr...

Plasma pyrolysis integrates thermo-chemical properties of plasma using pyrolysis process for safe disposal of solid wastes. It is an environment friendly technology to generate valuable byproducts by converting municipal solid waste, biomedical waste and hazardous wastes at 800-1000°C. Plasma Pyrolysis of plastic wastes generates pyrolysis gas, which can be utilized for energy recovery via diff...
