Description of Project ActivityThis project is to generate biogas containing methane from garbage at resort. The wastes like kitchen garbage, human waste and so on are collected in unaerobic tank. The biogas is generated by CH4 fermentation in the tank.
The biogas is used by phosphoric acid fuel cell (PAFC). Electricity generated by PAFC using biogas is supplied through private grid to the resort. Using the renewable energy at the resort will reduce oil consumption of diesel engines for generator and CO2emissions. Avoiding dumping the wastes at SWDS reduces CH4
emissions from SWDS in Phuket. In this project, there are two different ways of GHG emissions reductions. One way isto reduce methane emissions by avoiding from dumping waste. The other is to reduce CO2emissions discharged by oil consumption.
Targeted GHGCO2, CH4
Category of Project ActivityBiomass Utilisation
Duration of Project Activity/ Crediting Period2008-2023 (crediting period: 15 years)
Baseline Methodology/ AdditionalityBaseline methodology:
The waste water at the resort flows into sea without water treatment enough. The garbage collected at resort is brought out from here and dumped at SWDS in Phuket.
It is difficult to set up equipment that uses waste from which respect of the energy balance and the economic balance as a biomass, because the power generation efficiency of existing gas engines is low, and the maintenance cost is also expensive. Therefore, it is thought that this project have enough additionality.
Estimation of GHG Emission ReductionsThe project activity is estimated to reduce GHG emissions annually by 2,500-6,500 t-CO2e (total amount of GHG reductions through all project periods: 80,537 t-CO2).
Monitoring MethodologyApproved SSC methodologies Version 2 of Annex 10: Methodological tool - “Tool to determine methane emissions avoided from dumping waste at a solid waste disposal site”.
Version 12 of 1.A. – “Electricity generation by the user”
Environmental Impact AnalysisThrough this project, The generated waste can be made a resource and the waste water treatment system of facilities can be upgraded. As a result, the environment of resort can be maintained. And, in the effective use of waste, amount of garbage for landfill will have reduced. Moreover, the fuel for existing diesel electric power generations can be reduced by power generation by this system.
Issues and Tasks for Project RealisationThis project is CDM business of the Co-benefit type for Japan and Thailand, but the problem is whether the waste of a necessary amount and composition for this system can be collected. The composition and the amount would change according to the season and the number of guests, and there is no reproducibility. It seems that collecting amounts of the biomass by joint operation of resort we targeted and resort in the vicinity is also necessary.
