SCG, via its SCI Eco Services Company Limited, has joined with the Industrial Estate Authority of Thailand, the Department of Industrial Works, as well as communityleaders and entrepreneurs in the Map Ta Phut area to conduct a feasibility study on the possibility of upgrading industrial waste disposal based on the Circular Economy concept.

The new industrial waste-power plant will use Japan's gasification with ash-melting technology. Located in the Map Ta Phut Industrial Estate, this plant is a spinoff business built on the principle of a circular economy. It will be the first in Southeast Asia to feature this world-class industrial waste-disposal technology, with the ability to handle both hazardous and non-hazardous waste using a closed-loop process. 

This plant is expected to conduct a test run later this year and start operating early next year. Its target is to process at least 50,000 tonnes of industrial waste by the end of next year. SCG is confident this industrial waste-power plant will become a model business in demonstrating how resources can be utilised efficiently through a value chain based on the circular economy principle, paving the way for sustainable growth in business, industrial, social and environmental sectors.

Chana Poomee, vice president for Cement and Construction Solution Business at SCG Cement-Building Materials Company Limited, said SCG recognises that circular economy is key to sustainable economic, social, and environmental development. The company has applied this concept to its business operation under the SCG Circular Way with the belief that such guidelines will usher success when its implementation begins. 

SCI Eco Services Company Limited, in line with SCG’s Circular Way and its “Zero Waste to Landfill” policy, has launched many initiatives, especially in the area of industrial waste management. Among them are solid pre-treatment plant, liquid waste mixing and community waste management projects. Most recently, the company developed an industrial waste-power plant in Map Ta Phut as a prototype business based on the principles of the circular economy.

“We are aware that industrial waste without proper management can affect the environment and communities a great deal,” Chana said. “As a first in Thailand to properly treat industrial waste in cement kilns, SCI Eco Services is leveraging our expertise spanning more than 20 years to take industrial waste management to new heights. We have spent over three years working with the Industrial Estate Authority of Thailand, the Department of Industrial Works and Map Ta Phut community leaders to conduct an environmental health impact assessment [EHIA] and a feasibility study to set up an industrial waste disposal and power plant that complies with law and supports the concept of circular economy. With a budget of more than Bt2.4 billion, we are bringing Southeast Asia's most advanced technology to this plant, which is being constructed with green supply chain management on 15-rai expanse of land in Map Ta Phut Industrial Estate."

Sanit Kessuwan, business stakeholder engagement director at SCG Cement Company Limited, added, “We always keep our eye on modern innovations and technologies that can be introduced to help drive our business progress. Gasification with ash melting is the most advanced industrial waste disposal technology in Southeast Asia, and it coincides with SCG’s circular economy and ‘Zero Waste to Landfill’ approaches. This process leaves no residues for disposal, but by-products that can be reused to make the most of resources."

Panya Sopasriphan, deputy director for business stakeholder engagement at SCG Cement Company Limited, said: “The plant’s operation is a closed-loop system. It will feature pollution and waste control systems that comply with internationally recognised standards, from reception of industrial waste from entrepreneurs and transport to sorting centre for pre-disposal evaluation and analysis through to the disposal in gasifier and ash-melting furnace. While post-combustion residues such as aluminium, steel and fly ash are recyclable, others that are incombustible can be used as alternative materials for road construction. The power derived from the process can used for electricity generation while the water can be treated for reuse. This plant will have a capacity to process 65,000 tonnes of industrial waste per annum.”

Chana said: “We have implemented the plan to raise public awareness among target groups and local communities, highlighting the plant’s remarkable technologies, standards, and residue-free waste disposal. Our main target groups are industrial plants in the East, particularly those from automotive industry, refinery industry and electronics industry. Also, we want to invite entrepreneurs from all industries to accord importance to the need of properly disposing industrial waste so as to drive Thai industries towards sustainable growth. To reaffirm our commitment to Circular Economy promotion, SCG will hold the 10-year SD Symposium ‘Circular Economy: Collaboration for Action’. This seminar will address environmental issues that affect society and present success stories from various parts of the world.” 

The symposium will be held on August 26 at Centara Grand and Bangkok Convention Centre at CentralWorld. More information is available at www.scg.com/sdsymposium.
