About the programme
The treatment of livestock manure by way of anaerobic digester processes leads to the production of a biogas consisting of 60% methane (CH4). Without the adoption of the PoA, the farms would have employed normal scraping and hose-down cleaning of the animal waste with a series of anaerobic lagoons within the farms premises. This waste material would have been left to decay in the individual facility’s anaerobic lagoon system, producing significant amounts of methane directly to the atmosphere. These livestock waste management practices generally contribute to significant air (odour) and water pollution in the areas close to the farms. The PoA has applied anaerobic digesters to capture the biogas which has been utilised to generate electricity for the farms’ internal consumption.
How do we contribute to reduce the emissions?
The purpose of this Programme of Activities (PoA), developed by Energy Research and Development Institute – Nakornping of Chiang Mai University (ERDI) is to reduce greenhouse gas (GHG) emissions from piggeries manure in Thailand by converting anaerobic lagoons to closed anaerobic treatment digesters with biogas capture and power generation.
The installed technologies (anaerobic digesters) capture methane for use in power generation and provide other environmental benefits, human health and GHG reduction. The electricity generated from the project activities is utilized within the farm premises, reducing the dependence on electricity grid. Excess gas is channelled to the flare to avoid venting of biogas, as well as to ensure the project safety. The effluent from the digesters is discharged to a series of post-treatment lagoons for further use as irrigation water and recycles within the farm with no further discharge off-farm.
