Reduce use of paper cups
A total of 50,000 office paper cups were used in 2024 |
Reduce the use of disposable paper cups by 20% per year, and will eliminate the use of disposable paper cups by 2029. |
Reduce 194 kg of carbon dioxide equivalent |
|
Reduce use of office paper
A total of 250 million pieces of office paper was used in 2024 |
Reduce the use of office paper by 5% per year, and will decrease it to 65% of the 2023 level by 2030. |
Reduce 2,625 kg of carbon dioxide equivalent |
|
Encourage carpooling
In 2024, the total mileage of domestic major commuter routes was 69,800 kilometers |
30 carpools are added to each commuter hub, saving the driving mileage of 5,190 kilometers per year. |
Reduce 897 kg of carbon dioxide equivalent |
|
Eliminate the use of bottled water
12,000 bottles of bottled water were used in 2024 |
By 2030, the use of bottled water will nearly reach zero. |
Reduce 2,160 kg of carbon dioxide equivalent |
1. Comprehensive Management of Compressed Air System
The company has carried out a special campaign to address air leakage issues at all its production bases, significantly reducing the overall load and power consumption of the air compressors:
- By using technologies such as ultrasonic detection to locate and repair leakage points, waste is prevented at the source;
- Replacing ordinary air guns with energy-saving ones, and optimizing the design of the nozzles to reduce gas consumption while ensuring the process;
- Implementing pipeline pressure reduction treatment and intelligent centralized control for the air compressors, optimizing their loading and unloading logic, and installing intelligent drainage devices in the post-processing stage to prevent compressed air from being discharged along with condensate water.
2. Intelligent algorithm-controlled temperature regulation for central air conditioning system
We have introduced a centralized control system for central air conditioning based on predictive algorithms:
- Based on weather forecasts, production plans, and real-time temperatures in the workshop, the operating frequencies and start/stop of refrigeration units, cooling tower fans, and chilled water pumps are dynamically optimized to ensure that the system always operates within the highest energy efficiency range, avoiding overcooling and energy waste;
- This intelligent control has been extended to office scenarios, implementing strict seasonal mode unified management for the central air conditioning in the office area;
- Centralized intelligent control of the central air conditioning system is implemented, optimizing the operation of the main unit and auxiliary units through algorithms to improve overall energy efficiency.
3. Waste heat recovery
- Implemented steam condensate recovery projects at multiple production bases, recovering the high-temperature condensate back to the original water tank for boiler water replenishment, significantly reducing the heat energy required for heating fresh water;
- At the Shaoxing base, we transformed the air boxes of the air conditioning units into heat pipe energy-saving mode, utilizing the heat from the outdoor air in summer to preheat the fresh air, reducing the energy consumption for subsequent cooling.
4. Comprehensive lighting energy-saving renovation
- Replace all traditional lighting fixtures in factory workshops, warehouses, and office areas with more energy-efficient ones;
- Implement time-based and area-specific control for lighting and street lamps to directly reduce the basic electricity load.
5. Reconstruction of the refrigeration system
Introduce a cooling tower plate heat exchanger system and connect it in series with the existing screw compressor. During the transitional season and winter, prioritize using the natural cooling source of the cooling tower for refrigeration, and only activate the screw compressor as an auxiliary measure in the hottest summer, significantly reducing the electricity consumption for refrigeration.
