ACKNOWLEDGEMENT It is a pleasure to acknowledge Eugene Aleshin Library of Congress Catalog Card Number 78-51970 FOREWORD The United States, as a modern industrialized nation, is the product of constantly advancing technology. Our mobility, our affluence, and our high overall standard of living are manifestations of technological progress. So is solid waste pollution. - Technology can and does create pollution. Fortunately, it can also be applied to control and abate this very same pollution. In these days of energy shortage, we can no longer ignore the importance of solid wastes, no matter what form they take on - industrial, mining, agricultural or domestic. The importance of handling, discharge and conversion of solid wastes is of public concern. Our environment must be made compatible to ecological consequences. It is the objective of the Sixth Mineral Waste Utilization Symposium to be of service to those who are sincerely concerned in both energy and environment, and who wish to share their views to evolve either directly or indirectly in the practice of recycling and disposal of solid wastes. Recycling is an economic phenomenon. The extent a given material is recycled is a function of the values of socalled secondary materials in relation to so-called virgin materials. These relative values can change as a result of many factors, including changing technology, tax policies, transportation and new applications. It is the theme of this Symposium to look at both technical and economic factors, to describe progress over the last ten years, to point out problems resulting from utilization of solid wastes and development of new solutions to these problems.
