Household waste is dominated by organic waste ( ca.

Since the household sector is the largest waste producer in Indonesia, targeting this sector is very relevant.

Implementing waste reduction at the source as a waste management strategy is of great importance for reducing environmental pollution as well as the risk it poses to the local population. The current waste management system can have a more immediate devastating effect, as was the case in Bandung in 2004, when the landfill in Leuwigajah slid and buried local residences, resulting in 141 casualties and costing approximately US $434 million in losses. Some of the landfills are not equipped with a leachate treatment system, potentially releasing dangerous pollutants into the environment. Regarding treatment facilities, 47% of the landfills do not have appropriate supporting facilities and where supporting facilities do exist, 10% of them do not work properly. It is thus concluded that introducing biogas production from waste to improve waste management and reduce LPG consumption can be feasible when efforts to support the market uptake of bio-slurry, enhance biogas utilization, and improve procedural justice performance, are taken. Furthermore, while the produced biogas is perceived to be quite useful in substituting LPG, it has not yet been fully utilized due to low bio gas pressure and several technical failures, which in turn influence community acceptance of the digesters. From a social perspective, community acceptance is mainly influenced by procedural justice. The results show that the conversion of food waste into biogas is currently not economically feasible, mainly due to the low penetration of bio-slurry-a by-product commonly used for fertilizer-into local fertilizer supply-chains. This study assesses the socio-economic feasibility of the project in Cibangkong, a typical urban area in Bandung, which includes four bio-digesters. Although the produced biogas is sufficient, the socio-economic aspects can hinder application. Since 2010, biogas production from food waste has been introduced to reduce waste and provided an alternative to liquid petroleum gas (LPG) as cooking fuel in a pilot project in Bandung. Household waste is a serious environmental problem in Indonesia, especially in urban areas.
