Eco innovation has been incorporated into SCG Chemicals’ strategy, in line with the SCG Sustainable Development Pathway. It incorporates:
Eco factory development, consisting of production efficiency enhancement leading to reduction of natural resources utilization and environmental pollution, at the same time raising eco efficiency.
Eco supply chain improvement, which includes enhancing efficiency of trading and business partners and minimizing their impact on the environment.
Eco products, involving development of products and production processes with a view to delivering environmentally friendly products.
Eco-to-other-organizations which includes participation in development of communities, schools, and temples to instill awareness and to encourage undertakings aimed at environmental conservation, as well as to promote sustainable enterprises among communities in order to move towards Eco Industrial Towns.
SCG Chemicals sustainable development strategy is established for use as guidelines for work plan preparation.
Green Commitment: An organization shall have policy and commitment to reduce environmental impacts and effectively communicate among the various levels of the organization.
Green Activities: An organization shall establish and implement program(s) to reduce environmental impacts based on the policy and commitment from level 1.
Green System: An organization shall have either systematic environmental management (including monitoring, assessment and review for continuous improvement) including well-recognized environmental management award and certificate.
Green Culture: An organization shall demonstrate everyone’s accountability on environmental and social concerns as an integral part of the organization’s culture.
Green Network: An organization shall incorporate entities of their supply chains into the green industry umbrella.
On the use of raw materials
Stress has been placed on increasing production efficiency and Eco Symbiosis. Since 2007, 80,000 tons per year of raw materials has been reduced or reused. Projects implemented included:
The Gas Recovery Project at olefins factories.
The Vent Gas Recovery Project of Thai Polyethylene Co., Ltd.
The Off-Gas Recovery Project
The project to recover PTA residues as a partial substitute of raw materials
The Mould Design Project (with the objective of reducing runner waste)
The Project to recover methyl metacrylate produced in the cleaning process
On energy and greenhouse gas
Emphasis is placed on improving production efficiency, waste heat recovery, the use of biogas and Industrial Eco Symbiosis. As a result, since 2007, over 3,100,000 gigajoules of energy has been saved each year, which translates to reduction of 255,000 tons of greenhouse gas emission per year. A solar roof project has also been implemented with a capacity of 743 kWh/day (1,014,000 kWh/year), equivalent to reduction of greenhouse gas emission by 590 tons per year. Among the projects implemented were:
The emisspro® Project
The Absorption Chiller Project
The Energy Conservation Project (ENCOP)
The Wastewater Treatment System Biogas Project
The Flare Gas Recovery Project
Installation of an economizer to reuse waste heat in heating boiler inlet water
Water and wastewater management The 3 R’s (Reduce, Reuse and Recycle) and Industrial Eco Symbiosis are the main principles adopted (e.g., reduction of water loss in the production process and the reuse of waste water). As a result, the use of water from external sources could be reduced by 2,700,000 cubic meters per year. Projects implemented included:
Installation of an RO System for recycling of cooling water
The Mixed Salt Recovery Project for Reuse as a Raw Material in paper factories (implementation still underway)
Air quality management
This involves reduction of the release of pollutants into the atmosphere executed from the design state, production control, monitoring, to preventive maintenance.
Installation of an Aluminum Dome Roof
Installation of a Vapor Recovery Unit
Installation of Ultra Low NO2 Glow Plugs
Installation of a De NOx System to reduce NOx produced during combustion
The 3 R’s (Reduce, Reuse and Recycle) and Industrial Eco Symbiosis are the main principles adopted to reduce the quantity of waste and to recover waste. Projects implemented included:
A Study on Production of Fertilizer from Bio Wastewater Sludge
Installation of an Anaerobic WWT system to reduce sludge from wastewater treatment
Recycling of insulation waste for making refractory bricks
Chemical and hazardous material management
Chemicals in factories are managed in accordance with their compatibility, leakage prevention, emergency response preparedness as well as substitution of existing chemicals with less hazardous substances:
The switching of PET resin color changing agent from cobalt acetate to the Red/Blue toner
Termination of the use of hydrogen peroxide in the wastewater treatment system
On Green Supply Chain
Encouraging trading and business partners to engage in environmentally friendly goods and services, procurement of goods and services causing minimum environmental impact, as well as turning out more environmentally friendly products. In 2014, SCG Chemicals made a total of 1.05 billion baht worth of green procurement and received several certifications for environmentally friendly products, such as Carbon Reduction Labels, Carbon Footprints of Product Labels and SCG Eco Value Labels.
T.U.X™ Film : High quality film for food packaging
A sealant layer film for food packaging developed through cooperation between SCG Chemicals and Mitsui Chemicals Tohcello, a leading Japanese packaging manufacturer. This thin, clear and durable film, with its ability to withstand penetration, can provide assurance that packaged products are clean, safe, and free from contamination. Besides, the unique characteristics of T.U.X. ™ allow the film to be made thinner, resulting in reduction of the use of plastic and production cost.
Eco Plastic Chair
Made from eco materials with 30% natural content and polypropylene (PP), this chair product helps reduce the use of plastic, an alternative way for environmental conservation.
5 Gallon PET Water Bottle
Made with polyethylene terephthalate, this type of drinking water bottle is BPA (Bisphenal A) free, clean, and safe. It is not a hazard to health, has light weight, is clear and durable, and is certified by the FDA.
