The PoA aims to improve the livestock waste management practice, reduce GHG emissions, and take advantage of the captured renewable energy of livestock, namely swine, farms in different areas of Thailand. The project activity is to convert anaerobic lagoons to an enclosed system which capture and utilize methane to generate electricity/heat for consumption within the participating farms. The Energy Research and Development Institute of Chiang Mai University (ERDI), is serving as coordinating/managing entity of the PoA and is responsible for PoA, and subsequent CPA, preparation and implementation. ERDI will provide complete CDM service to the participating farm as well as additional technical support for waste management system operation and monitoring. The estimated amount of emission reductions over the 10 year fixed crediting period will be defined in each CPA. It will depend on the number of farms participating in a given CPA but this would not surpass 60,000 tCO2e per annum. The first CPA will generate a total of 557,740 tCO2e.
Currently most farms in Thailand employ normal scraping and hose-down cleaning of the animal waste with a series of anaerobic lagoons within the farms premises. This waste material is left to decay in the individual facility's anaerobic lagoon system, producing significant amounts of methane that is emitted directly to the atmosphere. The treatment of livestock manure by way of anaerobic digester processes leads to the production of a biogas consisting of 65% methane (CH4). This current livestock waste management practices contributes to significant air (odour) and water pollution in the areas close to the farms.
The project will apply anaerobic digesters which will capture the biogas and use it to generate electricity for on farm consumption or sale to national grid or heat. In addition to improving the local environment quality, the project will also deliver local community benefits related to the creation of new jobs during the construction, operation and maintenance stages of the livestock wastewater management system and to the utilization of methane gas (CH4) as renewable energy resource for the farms. The project activities can also be replicated in other farms around the country which will lead to environmental awareness related to livestock waste management, renewable energy, and climate change.
