Waste treatment to improve recycling and minimise environmental impact

This Special Issue is dedicated to the 11th Conference Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction-PRES 2008. Fifteen papers have been selected and after being peer-reviewed nine were accepted for publication covering important subjects of energy generation and usage. They are focusing on recent development of waste processing and recycling which is an important methodology for increasing energy efficiency and saving. The variety of approaches covered thermal degradation, sludge dewatering, combined coagulation/flocculation and adsorption, LCA and exergy analysis, biological denitrification, minimising Carbon Footprint, R. capsulatus on acetate, environmental performance assessment, and analysis of alternative secondary heat. It covered various features of waste. This issue of Resources, Conservation and Recycling is the fourth special journal issue dedicated to selected papers from PRES conferences.
