TURNING WASTE BIOGAS INTO ELECTRICITY IN THAILAND

TURNING WASTE BIOGAS INTO ELECTRICITY IN THAILAND

CONTEXT

All production processes generate waste in some form. The production processes at distilleries generate large amounts of wastewater containing a high concentration of organic waste, which – when left untreated in open lagoons – leads to potent greenhouse gases like methane being released into the atmosphere.

Because of the climate impact of these emissions from organic waste, it is vital to ensure the treatment of as much waste as possible, to minimise the potential for output of harmful greenhouse gases when the waste decomposes.

One way to do this is to use methane digesters, which harness the power of microbes to transform organic waste into biogas (an energy source) and digestate (a nutrient-rich fertiliser).

PROJECT

This innovative project mitigates greenhouse gas emissions caused by the decomposition of wastewater from the Thai San Miguel Liquor (TSML) distillery in Bangkok, by capturing biogas from wastewater and converting it to electricity in newly-installed engines.

The process uses methane digesters – by installing a digester between the exiting sump pit and the lagoons, the wastewater is treated, with the subsequent captured methane used as biogas for electricity production.

Previously, wastewater with a high organic matter content was treated in an anaerobic lagoon which during the organic decomposition, led to the escape of methane into the atmosphere. The project reduces greenhouse gas emissions by capturing the biogas before it enters the atmosphere and converting it into electricity. The electricity is then used to replace the fossil fuel energy which powers the TSML boilers, and is also exported to the Thai national grid. Estimated emissions reductions from this project around over 87,000 tonnes per year.

As well as providing jobs and training directly linked to the project activity, the project owner also engages in a wide range of social initiatives and educational programmes, including funeral care and sponsoring gifts for the Ton Lum Yai temple during Loy Kratong Festival.

CLIMATE SOLUTION #68 - METHANE DIGESTERS

Industrial-scale anaerobic digesters control decomposition of organic waste, and convert methane emissions into biogas, an alternative fuel, and digestate, a nutrient-rich fertilizer.

One option is to control decomposition of organic waste in sealed tanks called anaerobic digesters. They harness the power of microbes to transform scraps and sludge and produce two main products: biogas, an energy source, and solids called digestate, a nutrient-rich fertilizer. The digestion process unfolds continuously, so long as feedstock supplies are sustained and the microorganisms remain happy.

When produced at industrial scales, biogas can displace dirty fossil fuels for heating and electricity generation.
