Waste Management

SCGP manages elimination of pollutants, and industrial waste according to 3R's (Reduce, Reuse, Recycle) and Circular Economy principles. We continuously improve, upgrade the production process and develop research and innovation to maximize pollutants and waste reductions throughout the supply chain. We also recycle the production waste as raw materials and waste-to-alternative fuel, also convert to value-added products. Therefore, we can reduce the use of raw materials from natural resources and minimize the impacts on the environment and society.

Strategy

Reducing waste at the source, along with establishing indicators for ongoing monitoring and evaluation of the results.

Sustainably managing industrial waste (both hazardous and non-hazardous) based on the 3R (Reduce, Reuse, Recycle) and Circular Economy principles in relation to standards set forth by authorities and world-class organizations.

Creating added value and promoting Circular Supply Chain by integrating the Circular Economy principles into product and service development as well as innovation research and development for maximum material recovery & recycling efficiency. This approach focuses on designing products and services that facilitate efficient material reuse, and romotes the circular supply chain.

Product Life Extension by promoting research and development of innovations that extend the useful life of products and components, reduce waste, and decrease demand for new materials.

Sharing Platform for maximum resource management efficiency, which is operated through collaboration with customers, suppliers and stakeholders across the entire supply chain.

Transforming business model of “Selling Products” to “Products as a Service” with a focus on developing sustainable packaging in response to different customer needs in pursuit of maximum resource efficiency.

Joining national and international networks to pursue shared goals based on the Circular Economy principles.

Zero Waste to Landfill Policy

Zero waste to landfill from operations in Thailand since 2012.
Zero waste to landfill from operations abroad by 2030.
Zero waste disposal by incineration without energy recovery from operations in Thailand by 2025.

Highlight Waste Management Activities

Reduction of Waste in the Production Process

Reduction of Hazardous Chemicals in Printing Ink:

The vibrancy and aesthetics of packaging are major considerations for customers. However, printing ink pigments contain varying level of copper compounds. At SCGP’s Innovation and Product Development Center, the research team, in collaboration with the production team at Thai Containers Group SCGP, has explored methods for separating copper compounds from wastewater that has undergone post-production treatment (chemical precipitation). As a result, the production process now employs printing inks with reduced copper content, which are used in the production process to reduce the overall amount of hazardous waste. The initiative has been implemented across all SCGP container manufacturing plants.

Value-Added Management of Fiber Sludge from Filtration:

The fiber sludge extracted in the wastewater treatment process is repurposed as a raw material in paper production without compromising paper quality. In 2024, 10,660 tons of fiber sludge from filtration was successfully utilized.

In 2025, Siam Kraft Industry Co., Ltd. (Kanchanaburi) successfully reused 3,984 tons of fiber sludge, reflecting the Company’s commitment to efficient and responsible resource management.

Utilization of Starch Waste as Soil Amendment:

SCGP’s packaging box manufacturing plants now use tapioca starch as an adhesive in the production process. Treated water from the production process still contains starch sludge, which is a natural byproduct and is analyzed as non-hazardous. This starch waste is sent to Siam Forestry Co., Ltd., a subsidiary of SCGP , to be used as soil amendment instead of being disposed. In 2024, over 160 tons of starch waste was converted into soil amendment.

In 2025, the initiative was continued, with 161 tons of starch sludge recycled for use.

New Materials and Products from Waste

Processing Fly Ash and Bottom Ash:

Converting fly ash and bottom ash from boiler energy production process into raw materials for the development of various products - PROBLOCK-ECO Bricks, Miracle Blocks, and temporary and permanent barriers. In addition, bottom ash is blended with crushed stone and stone dust for the production of road base materials, and mixed with concrete to produce threehole concrete blocks. Siam Kraft Industry Co., Ltd. (Ratchaburi) has a production capacity of 10,000 blocks per month, while Thai Cane Paper PLC has a capacity of 100,000 blocks per month. These initiatives help reduce the amount of waste for disposal by 4,570 tons per year.

Training

SCGP has implemented the Environmental Performance Assessment Program (EPAP) which features an internal assessment component. This assessment framework was developed in collaboration with ERM Thailand, a reputable international environmental sustainability consulting firm. The framework covers five main components: governance, supply chain management, operation (related to waste management), product & service and stakeholder management & communication. SCGP conducted the training of EPAP to related employees in March 2024.

In alignment with the Ministry of Industry’s announcement on the Management of Waste or Unused Materials BE 2566 (2023), which came into effect in November 2023, SCGP organized a training session on industrial waste regulations and management best practices was organized by SCGP for relevant suppliers on 25 June 2024 to assist them in achieving compliance. A total of 29 waste management service providers attended this training session including SCGP employees related to waste management.
