Tofu has a favorite food in Indonesia, which has good nutritional been worth and the year affordable price, so the tofu industry is spread almost all over the districts in Indonesia. However, wastewater from the tofu industry has an environmental problem lead to social conflicts between industrial and communities. Biogas production has prospective technology that can utilize renewable energy resource reserves and cleanse wastewater through special treatment. The aim of the research is to evaluate environmental, social, and economic impacts on wastewater treatment in the tofu industry. Currently, tofu wastewaters from CV. Proma has been treated using anaerobic technology up-flow Fixed Bed reactor. The evaluation results show that technology can be reducing organic material in wastewater up to 83,38%. This technology is even producing biogas that can be used as energy substitution for the community and reduce CH4 emissions. The biogas produced equivalent to 5903 kg of LPG/years, which is able to meet the cooking needs of 40 households. Community perceptions show a positive impact because these activities provide economic benefits (Rp. 35.418.169/years) for the community around the tofu industry. Wastewater treatment can be reducing 2.863.981,8 kg of CH4 emission/years. The success of these technologies has supported goals SDGs number 3, 7, and 13.
