BOOK REVIEW :DEPONIEGASNUTZUNG (GAS UTILISATION FROM SANITARY LANDFILLS).V. Franzius, ed . Supplement 19 to the technical Journal "Müll and Abfall" . Published byErich Schmidt, Berlin, 1982 . Price: DM 69 .Reviewed by W. Obrist.

A seminar on gas utilization from sanitary landfills was held by the German FederalOffice for the Environment in March 1982 . Sixteen papers are reprinted in the supple-ment. They deal with the following topics :

•

Development and principles of gas utilization from sanitary landfills .•

Design and practical experience from existing plants with regard to their electric andthermal utilization .

•

Project planning .•

Effects of gas utilization on the planning and design of landfills .

The papers reflect the latest scientific and technical finding in this field, and describe therange of technical possibilities of gas removal and utilization from sanitary land-fills .

In addition to an outline of the historical development, technical measures for thetapping, treatment ;and storage of sanitary landfill gases are described based onpractical examples originating from the Federal Republic of Germany and the U .S. Datamostly from several years' experience are also given .

Optimum gas utilization under different conditions is then elucidated on grounds ofpractical considerations . Difficulties are encountered particularly with old and industrialsanitary landfills. The latest technological findings are described in detail .

So far the most common thermal and electric utilization processes and the appliedsystems and aggregates are described . The effects on the planning and operation ofsanitary landfills are elucidated .

All papers are coherently formulated and contain instructive data material . In mostcases, the texts are enriched with clear and comprehensive diagrams . Manufacturers andtrade names have been omitted . The question of economic viability is understandably onlyraised since it is not possible to give an exact economic estimate after such short operationtimes. The ecological effects in form of environmental damage prevention are describedrather briefly . They deal primarily with the control of odour nuisance, dangers of ex-plosion and vegetation damages .

On the whole, the work presents a good survey of the present technical pos-sibilities of intensive gas utilization from sanitary landfills on a large scale . It will alsobe of valuable assistance especially to people concerned with the planning anddesign of sanitary landfills as well as to specialists in charge of operation . Furthertechnical developments and scientific findings are, however, expected in this newfield .
