• Sommario/riassunto: Production-integrated environmental protection is synonymous with - reducing the amount of potential pollutants at source- reducing the consumption of resources and energy- recycling and utilization of residues and used products, and therefore a topic of considerable current interest.No chemical process exists that produces only the product desired. Therefore it is an important aim of the chemical ; industry to reduce the environmental effects of residues of chemical processes.This can be achieved by:- optimizing processes- applying new synthes
