    Farmer Sukrano from the Klaten distrinct is one of the 8,000 proud owners of a domestic biogas digester benefiting from the programme of activity.

    Methane emissions appearing as a result from the fermentation of the dung in the traditional way. Used as source for biogas, the gas escapes no longer into the air.

    On island Bali, where most of people are Hindus, farmers use the dung from their pigs for their biogas digesters.

    The programme covers nine provinces all over the country. On Java with its muslimic majority cow dung is the prevalent source for generating biogas.

    Sukrano mixes the cow dung with water which makes the fermentation proces more effective.

    This woman bought a special constructed stove working with the biogas from her own digester. On the right is a traditional stove requiring firewood.

    Crucial part of the whole programme is the collaboraton with manufacturing partners specialized of of the construction of stoves and lamps working with biogas.

    One of the key success factors is the customized advertising. The programme's claim 'Gratis Gas & Pupuk Setiap Hari' means 'free biogas and fertilizer every day'.

The overall objective of this climate protection project is the installation of domestic biogas digesters as a clean, sustainable energy source throughout Indonesia. Domestic biogas provides a sustainable way for individual households with livestock to reduce dependence on firewood and expensive fossil fuels.

Biogas digesters convert the dung into biogas that can be used for cooking and lighting. The slurry left over from this process is also an excellent organic fertiliser that can be used to improve crop yields.

The Indonesia Domestic Biogas Programme (IDBP), called the “BIRU programme” in Indonesia, aimed to construct 8,000 biogas digesters in 4 years (2009-2012) and was extended to the end of 2013 because of its high demand. BIRU means “blue” and is an acronym of “Biogas Rumah”, which translates as “biogas for the home”. Leaning on worldwide experience, the BIRU programme seeks to distribute biogas digesters as a local sustainable energy source by developing a commercial, market-oriented sector for them that also provides job and business opportunities for masons and partner organisations in construction.

The construction of biogas digesters in rural households reduce greenhouse gas emissions on different levels: the methane appearing as a result from the fermentation of the dung in the traditional way escapes no longer into the air. The methane is used instead as energy source replacing firewood or charcoal. The slurry replaces chemical fertilizers, whose production and transportation also is omitted. In addition, this organic fertilizer does not cause soil degradation as checmical fertilizers do. It has also an higher nutritional value compared normal animal manure.

The BIRU programme is implemented by Hivos, a Dutch non-for-profit organisation with widespread experience and international reputation. Hivos is working closely with the Indonesian Ministry of Energy and Mineral Resources and SNV Netherlands Development Organisation. The programme of activities covers regions throughout the country. On the island Java, with its Muslim majority, people use cow dung for their digester. On Bali Hindu people take the dung from their pigs.

At present, some 60 construction partner organisations and 3 manufacturing partner organisations (producing biogas stoves, lamps and other appliances) work with the BIRU programme. Almost 1,000 masons have been trained, and these numbers will increase as the programme expands. BIRU is planning to install another 26,000 digesters until 2017. The current programme focuses on 9 provinces, the second phase will include at least 12 provinces.
