A Cost-Benefit Analysis of Alternative Pig Waste Disposal Methods Used in Thailand

This study looks at the costs and benefits of the main pig waste disposal options used by intensive pig farmers in Thailand. It aims to see which alternatives give the most benefits to farmers and to society as a whole. It also aims to understand why farmers are reluctant to adopt biogas conversion technology, as this approach is being heavily promoted by the government. The study finds that, as it is currently implemented, biogas conversion actually provides fewer benefits than many of the other waste management solutions that are being used. However the report also finds that, if the necessary technical and financial support are extended to help farmers use biogas to produce electricity and sell this to the national grid, then biogas conversion would become a good option. The study recommends that the Thai government should provide technical and financial support to encourage pig farmers to install biogas systems and help them generate electricity and sell it. It highlights the fact that there is a pressing need to support and promote this renewable energy source, which would benefit pig farmers, the environment and the economy in general.
