ThaiBev embraces initiatives that reduce greenhouse gas emissions, focus on energy efficiency, and use resources sustainably. The goal is to increase the use of alternative and environmentally friendly energy. Today, due to the consumption of fossil fuels and the extreme accumulation of greenhouse gases in the atmosphere, global temperatures are rising.

ThaiBev therefore has made technological changes in its production process to use renewable energy as the main source of energy.

Awareness is also being raised among employees to make them understand the importance of the environment and society, inspiring them to better support the company’s green projects, such as the use of solar cells and the application of by-products from production processes as alternative energy sources.
ThaiBev Energy Audit Project

A company-wide project to assess the energy consumption of each production process and identify opportunities for energy efficiency. The project has enabled distilleries to reduce energy consumption by applying new technology. For example, beer and spirit product groups installed once-through boilers to increase energy efficiency and reduce the use of non-renewable fossil fuels. The beer product group cut its use of coal by 428 tons per year, resulting in a reduction of 702 tCO2e emissions per year.

The spirit product group was able to lower fuel oil consumption by 280,823 liters per year, which decreased greenhouse gas emissions by 836 tCO22e per year. In addition, the beer product group has introduced the use of high-efficiency motors, which reduced electricity consumption by 150,000 kilowatt hours (kWh) per year, and reduced emissions by 87.3 tCO2e per year.

Rooftop Solar Cell Installation

This project consists of the installation of solar panels on the rooftops of 27 factories in Thailand, and one factory in Myanmar. The installation will be completed by 2025, with a total capacity of 20 megawatts (MWp). It is projected to reduce the amount of electricity purchased from the Provincial Electricity Authority by 26,000 megawatt hours (MWh) per year, and lower greenhouse gas emissions by 12,000 tCO2e per year. It is expected that the project will reduce the cost of electricity purchased from the Provincial Electricity Authority by 96,200,000 baht.

Biogas Plant Installation Project

Two additional biogas plants will be constructed in Nakhon Sawan and Nong Khai provinces, in addition to the five existing biogas plants in Prachin Buri, Khon Kaen, Ubon Ratchathani, Buriram, and Surat Thani provinces. The biogas plants use the by-products of alcohol distillation to generate energy. Vinasse, a by-product of the spirit distillery process, produces methane as a fuel for steam production, and can also be used to generate electricity. This can reduce average annual fuel oil consumption by 2 million liters per factory per year, and lower greenhouse gas emissions by 38,000 tCO2e per factory per year. The electricity produced from biogas can be transmitted back to the grid.

What is the current plan for alternative energy use and greenhouse gas reductions?
“At present, the beer group plans to reduce energy consumption along with greenhouse gas emissions to comply with ThaiBev’s targets for 2025. The use of renewable energy will increase. Budgets have been allocated for replacing fossil-fuel based electricity with solar energy. We currently use biogas from the wastewater treatment system to replace the use of fossil fuels, through the installation of a once-through boiler. The group plans for future energy use to be sustainable. Energy consumption will decrease by modifying equipment for higher efficiency and lower power requirements. Efforts are underway to increase production efficiency by capturing carbon dioxide from fermentation to be reused in the production process (CO2 Recovery Plant). This can help lower electricity consumption, and also allow for the reuse of carbon dioxide in the production process that otherwise would be released during fermentation. The most important plan is to train employees and encourage them to participate in energy efficiency initiatives for maximum impact.

Within the beer group, a campaign has been launched to reduce and/or eliminate the use of plastic in factories, especially plastic straws, foam boxes, and products containing OXO-degradable or microbeads. Data has been collected and progress on this front is monitored continuously.”
