The purpose of the seminar was to increase participants' knowledge of methods for the construction of biogas digesters in detention facilities with a view to improving waste management and sanitation while providing an alternative energy source. This project is in line with the ICRC's policy of supporting prison authorities in their efforts to improve conditions of detention.

Prisons often have specific problems relating to poor sanitation and inappropriate treatment of waste effluents, which constitute a health hazard not only for inmates but also for neighbouring communities. Biogas digesters function as modified septic tanks, with an expected reduction of up to 100% of pathogens. They also store methane gas, which is produced during the anaerobic digestion of organic materials and can be used for cooking or lighting. They thus offer the additional advantage of reducing fuel costs and carbon emissions.

"The construction of biogas facilities for prisons is an innovative approach in addressing both the health concerns and the energy-conservation needs of prison authorities in the Philippines. This approach largely benefits inmates," said Juan Fuertes, head of the ICRC's sub-delegation in Davao City. "Three ICRC-supported biogas projects will be completed in Mindanao in the coming weeks," he added. During the seminar, participants also visited a biogas facility on a private farm in Digos City.
