Energy Management

Saved 39,143 MWh of electricity and reduced carbon by around 28,277 metric tons in 2021

Delta has long advocated and implemented environmental protection and energy conservation. All new plants and offices need to incorporate green building designs, and multiple energy-saving projects are actively promoted within the plants, offices, and data centers as it continues to achieve its goals and set new milestones in energy conservation.

  • From 2011 to 2021, each primary production plant has continued to implement energy conservation and carbon reduction measures (see the table below). The company put 285 energy conservation projects into practice in 2021 and saved approximately 39,143 MWh of electricity, equivalent to approximately 28,277 tons CO2e. Delta implemented a total of 2,555 energy saving projects from 2011 to 2021 with an estimated 318,529 MW of electricity saved, equivalent to a reduction of 245,079 tons CO2e.

Water Resource Management

Saved 165.8 megaliters of water

Delta has long been committed to improving water resources management measures and pursuing maximum water efficiency for its plants. In addition to prioritizing the use of water-saving equipment and devices, Delta strives to increase the water recycling rate, reduce waste water, and implement awareness-raising activities. Delta is committed to reducing its overall water intensity by an additional 10% by 2025, using 2020 as the base year.

  • Water Productivity Intensity at Plants: In 2021, the WPI of the overall production plants was 416 metric tons/million USD, a decrease of 8.2% compared with 2020.
  • Water Consumption Intensity at Buildings: In 2021, the WCI of seven buildings was 17.3 metric tons/Capita, a decrease of 21% compared with 2020.

Establishing Risk Assessment Mechanisms

Delta uses the Aqueduct Water Risk Atlas developed by the World Resources Institute (WRI) to identify the risks of Delta's supply chain and overall production plants. We scored each risk based on the risk elements and the results were used as the basis for Delta's internal decision making. We formulated corresponding measures to ensure adequate response capabilities, make adjustments before risks arise, and implement sustainable management of water resources. Delta shall continue to use the assessment methodology for high-risk plants and plan suitable measures for adaptation.

Water Consumption Review

A total of 80 new solutions for production sites and buildings were implemented in 2021, including: rainwater retention and reuse, condensate recycling, outlet pressure control, and equipment adjustment and improvement, saving a total of 165.8 ML of water consumption.

Waste Management

Reduced 3,986 metric tons of waste

Delta actively strengthens waste management measures, implements reductions from the source, increases the rate of resource reuse, and promotes closed-loop recycling to maximize resource utilization. Delta pledges 100% waste diversion rate by 2025.

  • In 2021, Delta's production sites in Dongguan, Wujiang, and Thailand obtained UL 2799 Platinum certification by attaining a 100% conversion rate for waste.
  • Delta continues to promote waste reduction measures, and a total of 64 waste reduction projects were implemented at overall production plants and buildings in 2021, including: recycling of packaging materials, adjustments of parameters to reduce the use of solvents, and sludge moisture content reduction, which resulted in a total of 3,986 metric tons of waste production savings.
  • Waste reduction reduced processing expenses by approximately 4.651 MUSD and the income from waste recycling totaled 9.495 MUSD.

KPI


  • Waste Diversion Rate

    Waste diversion rate = (reuse + reduce + recycle + thermal technologies + anaerobic digestion + biofuel + composting) / total mass discarded material

  • International certification and implementation

    Delta introduced UL 2799 zero waste landfill certification at Delta's Dongguan plant in 2019 and we have continued to improve waste monitoring, recycling, and reduction. We worked with suppliers on projects to gradually increase the resource recycling rate and expand the implementation to plants across the globe. In 2021, Delta's production sites in Dongguan, Wujiang, and Thailand obtained UL 2799 Platinum certification by attaining a 100% conversion rate for waste. We shall continue to pursue the goal of zero waste landfill for all Delta operations.

Value Chain Waste Reduction Results

Delta's waste reduction starts with its own improvements and it collaborates with the value chain to facilitate effective use of waste and reduce the production of waste. Delta plants have quantified value chain collaboration and overall effectiveness. The total amount of waste generated was 79,865.7 tons, and the total amount of all waste diverted was 79,466.3 tons, with a diversion rate* of 99.5%.

*Waste diversion rate = reuse + reduction + recycling + waste energy recovery + anaerobic digestion + biofuel + composting) / total weight of waste generated; of which, the percentage of waste energy recovery must be less than 10%.

Implementing Waste Management

Statistically, the total weight of waste at overall production plants processed by qualified disposal institutions was approximately 50,060.9 tons in 2021, of which, non-hazardous waste accounted for 46,042.2 metric tons (92%), and hazardous waste accounted for 4,018.7 metric tons (8%).
