SCG gives top priority to efficient waste management through consistent production process improvement alongside generating solutions for circularity. SCG promotes value-adding of excess raw material and waste by either finding use or designing new product to optimize the value chain. We do this by fostering collaboration with partners and suppliers, community, and stakeholders to develop a circular economy that fulfills every ESG dimension– environmental, social and governance.

Strategy

Synergy of the Circular Economy Network

Network	Project and Activity
Cement-Building Materials Partnership with Circular Economy in Construction Industry (CECI)	The King Bridge Tower Project Mainstreaming circularity into King Bridge Tower Rama III development project, from design process to procurement and construction. Building Information Management is used in design resulting in less resource use, reduction of onsite waste, and shortening the construction period. This is a groundbreaking pilot to showcase the path towards sustainability of the construction industry.   From pile waste to recycled concrete This onsite waste management aspect of construction projects is geared towards resource optimization and waste reduction. Pile wastes are ground to yield Recycled Concrete Aggregate, which is then used as constituent in recycled concrete for flooring-substitute materials in the project vicinity. The network currently is joined by Magnolia Quality Development Corporation (MQDC) in its Forestias, TCC Assets (Thailand) Ltd.’s  ONE Bangkok, Thai Obayashi’s O-Nes Tower and Central Pattana Plc.’s Central Sriracha project.
SCGC (Chemicals Business) and Ministry of Natural Resource and Environment, Fisher Folks Group of Rayong province, business partners and marine resource protection network	Nets Up Project Seeks value adding by recycling fishing net scraps into marine materials, employing technology and innovations to manage the whole chain from upstream to downstream. It starts with aggregating fishing net scraps through community garbage bank system facilitated by KoomKah mobile application. Inputs are fed into top-line recycling innovation to yileld High Quality Post-Consumer Recycled Resin. The output is subsequently shaped as fabric that can be used as textile, packaging, sports shoes, car parts, electric appliances. This is deemed upcycling, a new option for brands and consumers who care about the environment and marine trash pollution. The project has been piloted in coastal areas of Rayong. Plans are underway to scale up the project to 23 coastal provinces in the rest of Thailand.
SCGP (Packaging Business)  In collaboration with Thailand Institute of Packaging and Recycling Management for Sustainble Envionment (TIPMSE) and the Municipality of Sansuk, Banbueng and Koh Sichang in Cholburi and the network of producers, distributors, aggregators, and recycling plants.	PackBack Project for Sustainability   In this Extended Producer Responsibility (EPR) undertaking, PackBack manages used packaging for reuse in a concrete manner. First, producers are urged to build in circularity from design, collection, and separation, to allow for convenient and efficient reuse and recycling after use. – Packback has been piloted in the municipal areas of Sansuk, Banbueng and Koh Si Chaing of Cholburi in collaboration with TIPMSE, and 90 public-private partners.

From Waste to Product R&D

SCG keeps on coming up with solutions to turn waste to value.  The effort involves creative thinking combined with technology to generate new products that add value, are environment-friendly and consumer responsive.

Product	Waste to Value	Product R&D and Design
Cement-bag fashionwear	Used cement bags that can no longer serve the purpose of cement packaging	Cement-Building Materials collaborates with designer Chanachai Jariyathana of FRI27NOV brand, to design the technique of stitching cement bag and old jeans for a collection titled “The Day Yester Tomorrow” Under Sustainable Fashion concept. The collection made its debut at Bangkok International Fashion Week 2023 at Siam Paragon and is marketed online.
Water filter materials in fancy fish tank	Brick scraps from production process	Cement-Building Materials and Rajamangala University of Technology Srivijaya jointly develoed water filter from light-weight brick. Key features are extra pores with water contact surface of as high as 3,300 square meters per litre, 7 times higher than volcanic rocks, and suitable for microorganism to thrive. The effect is deacidifaction, reduction of ammonia and nitrate therefore making the water fit for marine creatures. The material is piloted at Siam Carp fish farm in Ratchaburi and is in pipeline for commercialization.
Miracle Block and “Khoo Din” soil nutrient	Flyash and bottom ash that constitute waste from burning coal for energy	SCGP (Packaging Business) invests in R&D to upgrade   ProBlock to Miracle Block with refractory quality, strength and bondability like Lego pieces that can be used in both permanent and temporary wall because it is amenable. Further, bottom ash and fly ash have been turned into soil nutrients marketed under the brand “Khoo Din” for agriculture.

Communication and Promotion of Circular Economy

Circular Economy Digital Platform Project

SCG has joined as advisor of the “Project to Develop Collaborative Model and Digital Platform for High-Impact Circular Economy” focusing on construction materials and packaging business. It is organized by Energy Technology Research for Environment of Engineering Faculty, Chiang Mai University. The purpose is to develop a waste management data base leading to value chain management of waste instead of transport for dispostal. Participating factories shall receive Carbon Foot Print (CFP) data from their circular economy activities.

CHOICE IS YOURS Project

SCG and six leading organizations initiaited the CHOICE IS YOURS project in 2023 and continuing in 2024 to open opportunities for youth at higher education level in a contest to come up with creative green ideas that benefit the environment the circular way. The theme for 2024 contest is Circularity for Community. Contestants will benefit from mentorship, knowledge and skills offered by six participating organizations. The winning team will have a chance to choose an internship at these participipating organizations. In 2023, over 220 students entered the contest from 22 universities nationwide.   

Quote

“We learnt about different approaches to waste management. We benefited immensely from the experience of working together as a team, application of technology, as well as creative and innovative thinking. With these we chose to intern with SCG because it is Thailand’s top enterprise.”

Waste Management and Reuse- Success Cases

1. Waste Management by recycling 84 tons of used papersby SCGP (Packaging Business)

In 2023, efforts continued with key projects such as:

• “SCGP Recycle: Old for New Paper Project” SCGP (Packaging Business) and Sino-Thai Engineering and Construction (STECON) organized “SCGP Recycle: Old for New Paper Project” to promote management, aggregation and separation of used papers from source and entered into recycling process to produce new paper. In 2023 the project recycled a total of 84 tons, equivalent to GHG emission reduction of 244.5 tonsCO2eq per year.

2. Waste Management by recycling 12,500 post boxes by SCGP (Packaging Business)

In 2023, efforts continued with key projects such as:

• “reBOX for the Blind” SCGP (Packaging Business) and ThailandPost continued the reBOX project collaboration, into its 4th consecutive year. Under this project, used post boxes are collected and sent to SCGP to produce packaging for agencies working with people with disabilities including the Thai Red Cross, Universal Foundation for Persons with Disabilities, Thailand Association of the Blind, Low Vision Association of Thailand, Thailand Association of the Blind Community. In 2023, the project recycled a total of 12,500 boxes.

Thai Polyethylene Co., Ltd., SCGC (Chemical Business) has studied and designed the Lights Chlorinator production process by improving quality and reducing the amount of waste liquid that used to be incinerated. Additionally, it can recycle 1,2 Dichloroethane (EDC) back as raw material more than 1,190 tons per year and can reduce expenses by approximately 15.13 million baht per year with an investment budget of 14.85 million baht.
