VACUUM AIDED RECYCLING SYSTEMS TECHNOLOGY (VARS TECH) AS A RESTORATION SYSTEMS TECHNOLOGY OF ECOFACTORY

The waste problem is now a vital matter from the aspect of environment al pollutants and effective utilization of natural resources. Vacuum A ided Recycling Systems Technology (VARS Tech) is a new recycling techn ology and is based on the concept of the Ecofactory as a next generati on manufacturing systems. In the present investigation, a fundamental study on the dezincing process of Zn and Zn alloy-coated steel sheets scrap by vacuum evaporation and development of a practical plant have been carried out. As a result, the VARS technology is confirmed as a h igh efficiency, high energy-saving technology which is usable for high quality material recycling with no ecological burden. Some additional applications of VARS technology for wastes are also introduced Copyri ght (C) 1996 Elsevier Science Ltd.
