Circular Economy

Everlight adheres to the principles of “maintaining and enhancing natural resources, optimizing resource use, and promoting system effectiveness” to promote the construction of a circular system. Through circular economy methods, we address issues related to energy efficiency, recycling, waste management, water management, material and resource flows, transportation logistics, air pollution prevention, and noise prevention, aiming towards the goal of “zero emissions and zero waste.”

▍Organization and Responsibilities of the Circular Economy Promotion Committee

Our company has established the “Circular Economy Promotion Committee”, which consists of task forces responsible for regulations, benefit evaluation, technology, production, and industrial cooperation. Additionally, two supporting groups – focusing on regulations and benefit evaluation – assist in jointly driving the development of the circular economy.

  • The committee shall have a chairman who is responsible for promoting and achieving circular economy goals, and the general manager of the company serves as the chairman. A deputy chairman shall assist the chairman in promoting circular economy, and the deputy general manager of the factory serves as the deputy chairman

  • Committee members are the leaders of each executive team.

  • An Executive Secretary is appointed, responsible for the relevant work and data collection and release of the Executive Committee’s resolutions.

  • Operation Method: The committee holds regular meetings in Q2 and Q4 each year to report and review implementation results, revise various circular economy goals and report upward.

  • Internally, the Company treat used substances through various methods (e.g., filtration, distillation, purification, activation, regeneration) to make them reusable in the production process or for other purposes, achieving circular reuse.
  • “Recycling dilute acid to produce ferrous sulfate“: In the dye manufacturing process, approximately 950 tons of dilute sulfuric acid are produced annually, which need to be neutralized and treated at a wastewater treatment plant. After improvement, the dilute sulfuric acid is mixed with purchased iron slag to produce ferrous sulfate, used as an environmental wastewater additive. This change is estimated to save about 3.6 million NTD annually in environmental treatment costs for dilute sulfuric acid and reduce the cost of purchasing ferrous sulfate by about 3 million NTD, totaling savings of approximately 6.6 million NTD.
  • The Company collaborates with upstream suppliers and downstream customers to recycle packaging materials or regenerate used raw materials, reducing packaging costs and process waste.
  • “Replacing raw material iron drum packaging with tank trucks“: By coordinating with suppliers to import large quantities of raw materials using tank trucks, Everlight can receive shipments in batches as needed for production. This change reduces 8,000 waste iron drums annually (financial benefit of 7.5 million NTD per year) and alleviates storage space pressure in plants.
  • “Recycling plastics for reuse“: Collaborating with external companies, the plastic waste used within the plant is recycled and converted into pyrolysis oil, reducing plastic waste disposal costs and achieving circular reuse.

Eight Stages of Industrial Cycle

Product Design
■ Developed AQ series products - anti-aging additives for water-based coatings. ■ Client solvent consumption is reduced by about 50% (12,500T/yr).
Material Selection
■ Coordinate with suppliers to import raw materials, establish inventory, and then package and supply them. ■ Packaging materials are reduced by 5,600 pieces/yr ($5.25 million).
Process Optimization
■ Esterification. ■ Alcohol consumption is reduced by about 30 tons/yr ($3 million).
Utilization of By-products as Resources
■ Zinc sulfate aqueous solution produced by process was successfully resold 2,690T/year. ■ Use of NaOH is reduced by 1,400 tons/yr.
Repair/Reuse
■ Pilot production line was built using equipment from factories within the Group. ■ Purchase of raw material storage tanks is reduced by $6 million.
Refining/Purification
■ Catalysts used in manufacturing process are reactivated and reused. ■ Catalyst purchase is reduced by 3 tons/yr ($1.5 million).
Classification/Collection
■ Process wastewater is classified and returned to appropriate process for use. ■ Water consumption is reduced by 2,400 tons/yr.
Regeneration
■ Dilute phosphoric acid is made into phosphate, sold to phosphoric acid supplier/for internal use. ■ Purchase volume of phosphate is reduced by 600 tons/yr ($3.6 million).
