Peace Corps' Information Collection & Exchange (ICE) was established so that the strategies and technologies developed by Peace Corps Volunteers, their co-workers and their counterparts could be made available to the wide range of development organizations and individual workers who might find them useful. Training guides, curricula, lesson plans, project reports, manuals and other Peace Corps-generated materials developed in the field are collected and reviewed. Some are reprinted "as is"; others provide a source of field based information for the production of manuals or for research in particular program areas. Materials that you submit to ICE thus become part of the Peace Corps' larger contribution to development.

Information about ICE publications and services is available through:

The Peace Corps Internet Web Site address:

Please note the new Peace Corps Mailing Address from July 1998 on is:

ICE/ Peace Corps
1111 20th Street N.W.
Washington, DC 20526

Add your experience to the ICE Resource Center. Send materials that you have prepared so that we can share them with others working in the development field. Your technical insights serve as the basis for the generation of ICE manuals, reprints, and resource packets, and also ensure that ICE is" providing the most up-to-date, innovative problem solving techniques and information available to you and your fellow development workers.

I would like to thank the many people whose help, encouragement, and invaluable advice made it possible for me to write this book. Among those to whom I am especially indebted are: Dr. Alfredo S. Mercado; Dra. Lolita L. Mercado; Engineer Patricio M. Bael, Jr.; Paul Taleon; and Erdie Mira. A special thank you to Peace Corps Volunteer John Hopkins who proofread the first edition and Martha W. Arnott who proofread the second edition. They put a lot of hard work into making my writing and editing readable. Many thanks to the United States Peace Corps and to Volunteers in Technical Assistance (VITA) for their support, resources, and encouragement.

This, the third edition of the book, would not have been possible without the invaluable advice and the graphic art and layout skills of graphic artist Sue Niewiarowski. I am also greatly indebted to Shirley Witchley for her perseverance with my notes and her skill with the computer/word processor.

I welcome letters from people working with biogas systems. I would enjoy discussing this book, the ideas in it, and all efforts to develop biogas systems and appropriate technology. I believe biogas systems have an as yet unrealized but very real potential for commercial success and social benefit.
