E: Environmental

As the reality of climate change becomes increasingly apparent, we are all conscious that humanity is currently consuming resources at a rate beyond the level our planet can sustain in the long-term. Although cement and concrete are, to date, among the lowest carbon-intensive building materials per unit of strength and per unit of cost, the concrete industry must play its part in continuously reducing the carbon intensity of the built environment.

Therefore, maintaining the balance between productions and caring for the environment is our important mission statement. Toward that end of creating confidence in our management of the environment, Siam City Cement Public Company Limited has adopted the ISO14001: Environmental Management System as the organization’s guideline in the management of the environment.

Inspired by the promise of a more sustainable and prosperous future for all, SCCC Group has devised the Sustainability Ambition 2030, in which Thailand Cement Business has shared the same ambition. However, we develop our ambitious targets based on business operations in Thailand, in alignment with all business units across the Group, to ensure that as a Group, we can really make positive impacts to the environment.

Climate & Energy

Global warming is one of the most urgent challenges the world is facing. If left unaddressed, it will impact both our climate system and the security of the population in general.

Thailand Cement Business, in alignment with SCCC Group, acknowledges the importance of this problem as well as the need to reduce carbon emission by developing a climate and energy ambition with achievable targets and initiatives.

Targets

(Scope 1) Reduce CO2 emissions by a further 25% to < 470 kg net CO2/ton from our 2020 baseline.
(Scope 2) Reduce electricity consumption and increase the deployment of alternative energy sources, thermal, and electrical.
(Scope 3) under study

Key Initiatives

Separate Grinding Project

The Company implemented a Separate Grinding Project at Plant 3 in Saraburi Province to reduce CO₂ intensity by lowering the clinker factor through changes in the cement production methodology. The project was implemented over 15 months from Q1 2022 to Q1/Q2 2023, with a total investment of approximately USD 12 million, and was completed in 2023.

The project supports the Company’s Climate & Energy strategy by improving production efficiency and enabling a lower clinker factor, thereby contributing to the reduction of carbon intensity in cement production.

Reducing Our CO2 Footprint in all markets

We continue to innovate the development of high performance and environmentally friendly products with lowered CO2 intensity
Hydraulic cement is a low clinker intensity and more eco-friendly product, manufactured with reduced greenhouse gas emissions.
INSEE Petch Plus is example of low-CO2 cement brands being well appreciated by our customers.

Waste Heat Recovery (WHR) system

The Company has been implementing Waste Heat Recovery (WHR) systems to recover waste heat generated from the cement manufacturing process and convert it into electricity for use in production since 1989 to optimize its operation as part of its ongoing decarbonization efforts.

This initiative improves energy efficiency, reduces reliance on electricity from conventional energy sources, and contributes to the reduction of indirect CO₂ emissions.

The WHR system is an integral part of the Company’s Climate & Energy strategy, supporting its Sustainability Ambition 2030 through increased energy efficiency and the use of recovered energy.

Circular Economy

The Company is committed to completely avoid using landfill for disposal and reduce the volume of solid waste gradually, aiming for Zero Landfill. We also embrace the concept of circular economy to reduce total waste, aiming to reduce waste from the sources. In addition, to guarantee no landfill disposal, we have adopted an advanced recycling system, which greatly reduces the amount of waste that requires disposal. One of our Group Companies, INSEE Ecocycle Limited, has operated with the concept of circular economy built into its business chain, offering waste management solution wherein waste is turned into a valuable resource through treatment in the cement kilns, which disposes of waste without resulting in pollutants, reduce reliance on fossil fuel, and minimize environmental impact.

Through INSEE Ecocycle, the Company also provides sustainable waste management solutions that support the recovery and utilization of waste materials. These include Refuse-Derived Fuel (RDF). The use of RDF as an alternative fuel contributes to the Circular economy by recovering energy from non-recyclable waste and reducing reliance on fossil fuels. It also supports the Company’s efforts to reduce greenhouse gas emissions associated with conventional fuel consumption and advance more sustainable waste management practices.

Biodiversity and Water

Biodiversity is essential for ensuring minimal impacts of our quarrying and mining activities on the planetary ecosystem. As the planet is very scarce on clean, palatable, drinkable water, we must play our part in preserving as much water as possible, especially the water usage in manufacturing our products.

Targets

Assure Net Positive Impact (NPI) on biodiversity by 2030
Lower water consumption (by > -20%) with enhanced use of surface water (to > +45% of all water used) by 2030

Siam City Cement Public Company Limited has been certified ISO14001 continuously for more than 20 years, with the scope of the current standard ISO14001:2015 version covering all major processes of the organization i.e., quarry operation, cement production and distribution, inventory management, and office operation and service.
