| Synopsis: |
In the past, it was often assumed that, in industry, technological alternatives simply did not exist, particularly in "core" processes. The case studies included here demonstrate that substitution possibilities do exist in both primary and secondary operations. Most of the case studies are based on field surveys and show the economic and technical feasibility of alternative techniques. Two of the case studies, on the minerals industry in the United States, Zambia, Zaire and Chile, and on the manufacture of tins in Kenya, the United Republic of Tanzania and Thailand, are inter-country comparative studies. Other case studies relate to particular industries in particular countries: jute processing in Kenya, sugar processing in India, cement block manufacturing in Kenya, shoes and bricks in Malaysia, textiles in the United Kingdom, engineering in Colombia, metal working in Mexico, and - new in this third edition - textiles and energy in the Republic of Korea. |
