All organic materials have energy embodied in them in the form of carbon. Theoretically this energy can be captured and transformed into other useful forms. It is a well known fact that energy can neither be created nor destroyed but merely transformed. One of the most common methods of transforming …

All human activities have an environmental impact. In particular, the way we choose to manage our residential solid wastes has a direct impact on the generation of methane, carbon dioxide and other greenhouse gases (GHG) linked to global warming and climate change.

The life cycle inventory (LCI) presented in this study quantifies the total energy requirements, energy sources, atmospheric pollutants, waterborne pollutants, and solid waste resulting from the production of recycled PET and HDPE resin from postconsumer plastic. This analysis does not include impact assessment. It does not attempt to determine the …
