Environmental management must be carried out in a sustainable manner and this is made possible when the efforts involved are easy, cheap, and whenever possible profitable. Therefore, environmental pollution prevention measures such as the Cleaner Production approach is well suited to be implemented in the environmental efforts in Organic Rubbish. Cleaner Production approach that is combined with Organic Rubbish will be the best approach for the environmental management of Settlements. This research is aimed to develop a new system that integrates the application of Cleaner Production and Organic Rubbish from Settlements. In this research, the waste from tofu that is turned into biogas as a form of renewable energy using an Biosam reactor, for which the waste mud from the sewage system serves as the inoculums. There are 5 approach for implementation: (1) workshop; (2) supervising; (3) technical meeting; (4) network meeting, and (5) technical application. Implementation of the Cleaner Production scheme that is integrated with Organic RubbishTreatment will reduce the amount of rubbish to be treated in the treatment facilities. This means less cost on the construction and operation of waste water treatment facilities, as inherent limitations with organic rubbish treatment facilities like lack of fund, limited area, and technological issues are already there. Implementation of Cleaner Production prior to organic treatment should be able to reduce pollution figures up to certain levels that limitations in organic rubbish treatment facilities can be covered. Biogas in 12 days HRT in an Biosam reactor contains CH4 (88.46 %) and CO2 (12.66 %). Meanwhile, treatment using conventional a bio-digester results in biogas with 88.46 % CH4 and 12.66 % CO2. Hence, biogas efficiency for the Biosam system is 2.54 times greater than using a conventional digester.
