Generally, it is accepted that for plastics recycling to be economically viable in the long term, recycled resins must be competitive with virgin resins. To compete with virgin material, new applications must be made available for recycled resins. Such applications will require that the recycled resin be of a high purity level. Thus, many processors are requiring ever-tightening contamination limi ...

The majority of buses, heavy-duty fleet vehicles, and construction and farm machinery are equipped with diesel engines. The diesel engine is an energy-efficient machine, but its exhaust emissions present a serious health and environmental problem. Drastic reductions of exhaust soot have been mandated throughout the world, including the recent U.S. Environmental Protection Agency (EPA) mandate to r ...

Post-consumer plastics have become a tremendous burden upon our waste disposal system. Although plastics constitute only about 9 percent by weight of municipal solid waste, they occupy approximately one-fourth the volume of the waste stream. The U.S. EPA recommends recycling of plastics as the best solution to the problem. However, contamination of plastics within the recycle stream by foreign mat ...
