Sustainable Integrated Bio-cycle Farming System (IBFS) is a good approach to integrate a multi-sector (Agriculture, Horticulture, Plantation, Forestry, Animal Husbandry, Fishery etc) to produce food, feed, fuel, fertilizer, pharmacy, edu-tainment, eco-tourism etc. Through technological strategy of 7R (Reuse, Reduce, Recycle, Refill, Replace, Repair and Replant) with added value in economic, environment and socio-culture aspect, this method can be approached as a characteristic of Education for Sustainable Development (EfSD). Tunnel digester for anaerobic digestion of organic materials produced organic fertilizer and bio-gas energy. The design of GAMA DIGESTER has been optimized to improve the methane (CH4) content in the biogas. The purity of methane in biogas increased to be 80% by the first generation of GAMA PURIFICATION unit. GAMA COMPRESSING unit, which is still under study for design improvement, is targeted to produce Compressed Methane Gas (CMG) in the near future. The GAMA DIGESTER, GAMA PURIFICATION and GAMA COMPRESSING could product sustainable bio-energy in the total system of IBFS.
