| Abstract | Cement industries are the important upstream for building material industries and they also importantto the economic of country . However, the processes of cement manufacturing are effect to environment. In the future environmental problems will become a business competition. Hence, the article focus on evaluate eco 8 efficiency and apply mathematical model to minimize material cost and fuel cost . The indices that apply for cement plants are material and energy eco 8 efficiency. These indices imply with cost of manufacture and also environmental influence. The assessment base on 5 factories ofcement group and assessed in 2008. The material eco 8 efficiency is 1,760 Baht/ton and energy eco 8efficiency is 926,000 Baht/Terajoules. Mathematical model show that the optimum solution for cement making should use limestone 1.25 kilogram clay 130 grams sand 60 grams and coal 95 grams and sugar cane {s leaves 60 grams to make 1 kilogram of clinker. In case of we can use biomass fuel. It can reduce manufacturing cost to 0.46 Baht / ton clinker and reduce environmental burden such as reduce greenhouse gas 25.78 % ,sulphur dioxide 25.06%,nitrogen dioxide 23.77%. So we can conclude that there is an improvement of eco - efficiency |
