Along with increasing the capacity for treating household waste to 2.520 tons per day, BIWASE (Binh Duong Water – Environment Corporation - Joint Stock Company, stock code BWE) is ready for the inauguration of its 5MW waste-to-energy plant, which will take place tomorrow, January 12, 2024.

Tomorrow, January 12, 2024, the inauguration ceremony for the 5MW waste-to-energy plant will take place.

Complete Circular Processing of Household Waste

According to estimates, the daily amount of household waste generated in Binh Duong province is approximately 2.350 tons. This waste is collected and transported to the Binh Duong Waste Treatment Branch (located in Chanh Phu Hoa Ward, Ben Cat Town, Binh Duong Province, also known as the Binh Duong Solid Waste Treatment Complex). 

Mr. Ngo Chi Thang, Director of the Binh Duong Solid Waste Treatment Complex under BIWASE, stated: “The trial operation of the 5MW waste-to-energy plant has stabilized and met technical requirements. We are currently completing the final items, including decoration and signage, in preparation for the inauguration ceremony on January 12, 2024.”
According to the process, waste collection trucks from various districts, towns, and cities in Binh Duong province, after passing through an automatic weighing station, unload their waste at one of the four reception pits. These pits also serve as the input for the four composting plants known as Con Voi Binh Duong. The total capacity of the four plants is 2.520 tons per day.
At each reception pit, the waste is separated from organic materials (which account for 50% to 80%) using conveyor belts, and then it is transferred to composting tanks for organic fertilizer production through a biological fermentation process. The remaining components are further separated and sorted to recover recyclable materials such as metals, sand, gravel, and glass. Before being sent to the incinerator, the waste is dried to ensure complete combustion. The ash and slag produced from the incineration are collected and used as raw materials for producing building materials and decorative bricks under the Con Voi – BIWASE brand.

Currently, the Binh Duong Solid Waste Treatment Complex is generating electricity directly from two units. Unit 1 utilizes methane gas from a temporary landfill area of 5 hectares, which ceased accepting waste in August 2023. Unit 2 generates electricity from heat recovery from the incineration plant, which has a capacity of burning 200 tons per day. Both units together provide a total power output of 5MW, meeting 80% of the electricity needs for the operations at the Binh Duong Solid Waste Treatment Complex. In the initial phase, since the plant is not yet connected to the power grid, the surplus electricity is self-consumed.
With a passion for their work and scientific expertise, BIWASE has transformed household waste into valuable products such as electricity, fertilizers, and construction materials, following a circular and environmentally friendly approach.

The Plant Designed and Installed by BIWASE
Mr. Ngo Chi Thang, Director of the Binh Duong Solid Waste Treatment Complex, stated that BIWASE has accumulated extensive experience in waste management. Before embarking on the design and construction of the plant, they consulted with many international experts. This process helped them select the optimal solution tailored to local conditions, and BIWASE’s team of experts and engineers undertook the design and installation themselves. Machinery and equipment, such as turbines, were imported from SIEMENS.
The project’s total investment is 835 billion VND (equivalent to over 34.4 million USD), with 364 billion VND (nearly 15 million USD) allocated for the organic fertilizer production unit and 471 billion VND (over 19.4 million USD) for the incineration plant combined with power generation. The project is financed by loans from the Asian Development Bank (ADB) and the Japan International Cooperation Agency (JICA), totaling 20 million USD, equivalent to 480 billion VND.
Mr. Thang added that increasing the plant's capacity, including the fertilizer production plant, is a contingency plan for the coming years to ensure the capacity to receive and process waste throughout the province. Since they have mastered the technology, many processes and details are produced directly at BIWASE Mechanical Workshop, offering better cost, price, and quality than imported equipment. This is a critical issue as many waste-to-energy plants in various locations have failed shortly after operation due to the corrosive effects of leachate, which deteriorates equipment within about two years of operation.

The inauguration of the 5MW waste-to-energy plant, designed, built, and operated by BIWASE's own experts and engineers, marks a significant achievement in waste management. This plant uses a circular process to convert daily municipal waste in Binh Duong Province into valuable products such as renewable energy (electricity), organic fertilizers, and construction materials.
BIWASE has achieved a remarkable milestone in independently developing a waste-to-energy plant, setting an example of Green Transformation and Sustainable Circular Economy.
