Chemical Recycling of Polymer Materials
After the first life cycle of plastics various recycling processes are available for further utilization of these valuable materials. For an ecologically and economically satisfying solution the most suitable process has to be chosen. In chemical recycling polymers are degraded to basic chemical substances which can be reused in the petrochemical industry. For soiled waste plastics or waste pla...
متن کاملAutomobile Recycling Policy: Background Materials
The issue of automobile recyclability is a problem with complex ramifications for car makers world-wide. Confronted with increasingly stringent fuel economy, emissions, and safety standards, recyclability is an attribute which can limit the ability of the automaker to meet these other goals economically. Nevertheless, social and political pressures upon the industry require that it responds to ...
متن کاملRecycling of CIGS solar cell waste materials
The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. The advantage of thin film solar cells is that they require less semiconductor material than conventional silicon solar cel...
متن کاملHigh Value Carbon Materials from Pet Recycling
Polyethyleneterephthalate, PET, has become one of the major post-consumer plastic waste. In this work special attention was paid to minimising PET residues and to obtain a high value carbon material. Pyrolysis and subsequent activation of PET from post-consumer soft-drink bottles was performed. Activation was carried out at 925 oC under CO2 atmosphere to different burn-off degrees. Textural cha...
متن کاملRecycling Organic Materials On Agricultural Lands
The recycling of rural and urban organic waste materials onto agricultural land provides a challenge to the producers and end-users who both have a 'duty-of-care' to ensure the method of disposal is managed in a sustainable way. Careful management means that soil and water resources are not contaminated, the agricultural production system remains stable, and land use alternatives remain availab...
