Circular Economy Demonstration Plant in 2020
Selected by the Ministry of Economic Affairs as a Circular Economy Demonstration Plant and hosted a national observation meeting attended by more than 50 enterprises.
Innovative Subscription Model Leading the Green Transformation of the Filtration Industry
We were the first manufacturer to offer the “Filter Subscription Service.” Our innovative business model not only optimizes resource efficiency on the customer side but also effectively reduces the environmental burden for the entire industry supply chain. Our pioneering achievement led to the Small and Medium Enterprise Award in the Outstanding Low-Carbon Operations Division of the 20th Global Views ESG Corporate Sustainability Awards that recognized our substantive action and influence in green transition.
The Largest AMC Control Equipment Provider in the Cross-Strait Region
At the same time, Yesiang is also continuing to promote energy-efficiency and carbon reduction measures, invest in the R&D of low-carbon technologies and products, as well as strengthen process efficiency and product life cycle management.
To enforce transparent governance and responsible supervision, we regularly publish our environmental protection targets and progress. These are tracked and verified by our internal auditing unit to ensure that our sustainability commitments are practiced during operations.
Transition from linear economy to circular economy
Yesiang has focused on AMC control in the semiconductor industry since 1987. The business model was also progressively and successfully transitioned from the legacy linear economy model to the circular economy model. Key Milestones:
“Activated Carbon Regeneration Center” opened at Yesiang Liuhuan Plant indicating that the mesh regeneration process is now in full mass production.
Green electricity introduced to produce the first batch of carbon neutral filters in the world for the first-ever “filtrated clean air subscription” in the manufacturing industry. Yesiang Liuying Plant set up a regenerative filter center and was chosen by the Ministry of Economic Affairs as a model enterprise for “digital and green transition.”Obtained Patent No. TWI873012B Frame Structure to Prevent Glue Overflow
Launched digital transition effort by introducing SAP, CRM, and MES systems. Governance carbon inventory capabilities were strengthened, and ISO 14064 certification obtained; planning for the construction of a regenerative mass production plant in Liuying, Tainan was planned. Patent portfolio expanded, with patents TWD215192 and TWD214761 awarded.
Commenced R&D on regenerative energy-saving products in alignment with the ESG goals of international customers. ISO 45001 occupational safety certification was obtained in the same year.
Established regenerative filter media research lab and introduced the 8 SGS indicators (ASTM activated carbon test standard) widely used in the industry.
Expansion of R&D department to boost technical capacity on filter generation.
Launched the removal stacked filter patent (TWI692600B et al.) to enhance filter maintenance efficiency and reclaim-ability.
Obtained patent for filter regeneration technology (TWI579064B) to strengthen the service time of filter media.
Obtained patent for reusable cylinder filter (TWM444214U) to launch R&D of reusable filter media.
Distribution of American chemical filter products and establishment of the basic professional foundations in AMC control.
R&D Investment and Intellectual Property Strategy
Yesiang plans to increase our investment of R&D resources to form a complete technology protection ecosystem.
The R&D budget and manpower have continued to grow each year.
The number of patent applications and trade secret registrations has continued to grow steadily every year.
Many patents and production process technology certifications for cylinder mesh regeneration have already been obtained to consolidate our technological advantage.
Low-carbon production process and energy-saving innovations
Environmentally friendly material design
Recyclable and reusable design were incorporated into the product at the source to reduce dependence on disposable materials:
- Refillable cylinder design effectively extends the life of the filter media vessel.
- Removable filter frame design reduces the overall frequency of consumable replacement.
Regenerative design
Used filter mesh and cylinders can all be recovered by the plant for reuse:
- Activated carbon regeneration technology for cylinder mesh developed.
- Set up mesh regeneration process and equipment to realize a sealed material cycle.
Net Zero Stage 3 Targets
Short-term Target
Reduce direct emissions
- Conduct product carbon (ISO 4067) and greenhouse gas (ISO 4064) inventories.
- Optimize the consumption of raw materials and introduce low-carbon materials.
Medium-term Target
Management of Indirect emissions
- Introduction of ISO 50001 Energy Management System to improve energy performance.
- Require supply chains to cooperate with carbon management measures.
Long-term Target
Net zero carbon emissions by 2050
- Incorporate carbon reduction targets into the KPI and link them to the employee discipline/reward system.
- Continue to engage in PDCA management loop to strengthen push for sustainability.
