The generous support of the Government of Singapore, the United Nations Development Programme (UNDP), the International Development Research Centre (IDRC), the Food and Agriculture Organization of the United Nations (FAO), the Australian Development Assistance Bureau (ADAB), the German Agency for Technical Cooperation (GTZ), and the Association of South East Asian Nations (ASEAN) is gratefully acknowledged.

The contributions of the over 100 persons who were involved in the projects highlighted in this book are thankfully recognized. The most rewarding part of the whole experience was the team spirit and magnanimous cooperation of the individuals from the various agencies, including those who administered aspects of the project without coming into contact with the actual work in Singapore.

This book is a product of the inspired leadership of Dr Ngiam Tong Tau. Dr Ngiam became Director of the Primary Production Department of Singapore in 1984. He had served previously as comanager of the internationally funded projects. Dr Ngiam was instrumental in obtaining the support of IDRC in 1985 to use the waste biotechnology facilities developed in Singapore to train some 45 environmental engineers and scientists from ASEAN and other regions on the art and science of waste management. The visionary leadership and outstanding contributions of Dr Ngiam are gratefully acknowledged.

I would also like to acknowledge the contributions of Mr Lee Kam Wing of IDRC and Mr Yap Boon Chark of PPD whose collaboration and encouragement during preparation of the several drafts of this book went beyond the call of duty.

The International Development Research Centre is a public corporation creased by the Parliament of Canadain 1970 to support technical and policy research designed to adapt science and technology to the needs of developing countries. The Centre's five program sectors are Natural Resources, Social Sciences, Health Sciences, Information Sciences and Systems, and Corporate Affairs and Initiatives. The Centre's funds are provided by the Parliament of Canada; IDRC's policies, however, are set by an international Board of Governors. The Centre's headquarters are in Ottawa, Canada.

For the island republic of Singapore, the decade from 1975 to 1985 produced the most phenomenal changes in its history. This textbook-cumresearch report chronicles one aspect of that change: the pig-farming industry. It covers everything from biomass recovery to malodour prevention and, while focusing on the Singapore experience, the approaches, conclusions, and technologies described are pertinent to all systems that must deal with organic solid wastes and wastewaters, particularly in the livestock industry of the world's tropical regions. This book is aimed at professional engineers, researchers, policymakers, and, in conjunction with other more basic textbooks, graduate students in waste management and environmental engineering.


Au cours de la décennie allant de 1975 a 1985, la République de Singapour a connu les plus importants changements de toute son histoire. Ce livre, qui est a la fois un manuel didactique et un rapport de recherche, porte sur les changements qui se vent produits dans l'industrie de l'élevage du pore. Il en aborde tous les aspects de façon exhaustive, de la récupération de la biomasse a la prévention des mauvaises odeurs. S'il met ['accent sur l'expérience menée a Singapour, les approches, conclusions et techniques qui y vent décrites peuvent convenir a tous les systèmes ou il y a production de déchets organiques solides et d'eaux usées, et tout particulièrement a l'industrie de l'élevage en milieu tropical. Ce livre s'adresse aux ingénieurs, chercheurs et décideurs, et, utilise avec d'autres manuels plus fondamentaux, aux étudiants de cycle supérieur dans les domaines de la gestion des déchets et du génie de l'environnement.


Para la isleña república de Singapur, la década de 1975 a 1985 produjo los cambios mas espectaculares en su historia. Este informe combinado investigacioón-libro de texto, establece la crónica de un aspecto de ese cambio: la industria de la cría del ganado de cerda. Abarca prácticamente todo, desde la recuperación de la biomasa, hasta la prevención de los olores ofensivos y, mientras que el texto se centra en la experiencia de Singapur, los enfoques, las conclusiones y las tecnologías descritas son aplicables a todos los sistemas que tratan con desperdicios, desechos y aguas residuales, especialmente en la industria ganadera de las regiones tropicales del mundo. Este libro se dirige a los ingenieros profesionales, investigadores, responsables de la formulación de polítical y en conjunción con otros textos mas básicos, a los estudiantes graduados en la gestión de desperdicios y basuras e ingeniería del medio ambiente.
