Accelerate the Development for a Low-Carbon Future

Advancing climate actions

Regarding "low-carbon" as a key element in the 2030 vision blueprint, Topband adhered to the concept of sustainabledevelopment, relied on intelligent and low-carbon development, actively fulfilled the requirements of green and low-carbondevelopment policy, and promoted the environmental management in a scientific and systematic way. With its technical advantages inintelligent control, Topband explored the low-carbon way of manufacturing industry, and worked with upstream and downstreampartners to carry out technological and product innovation, aiming at building a more environmentally friendly coordination model andjointly promoting the realization of the "dual carbon" goals.

An energy management team was formed in March 2023 to lead the energy saving work from office, production, procurement,delivery and other aspects, and explore the practices of using renewable energy and energy-saving equipment to improve energyefficiency. Meanwhile, a pilot online energy management platform was established in Huizhou Park, which regularly assesses theenergy usage and ensures the authenticity and accuracy of the monitoring data.

Energy transitionThe Company has built a green park for "PV power generation + energy storage". Specifically, on the basis of the original 513 kW PV power generation system, Shenzhen, Huizhou, Ningbo and Ninghui Parks increased PV installed capacity of 240 kW, 941.28 kW, 1,479.08 kW, and 1,490 kW, respectively, in 2023, with a total increase of 4,150.36 kW and an increase rate of 709.04%. Meanwhile, the Shenzhen Park was equipped with 1,000 kWh lithium storage cabinets for peak and valley regulation in the park. In 2023, the PV power generation facilities in Shenzhen and Huizhou Parks generated energy of 2,239 MWh, and the energy storage systems in Shenzhen Park generated benefits of RMB 39,600.
Energy conservation transformationTemperature regulation in summer in the parks is a major source of energy consumption for Topband. The Company installed 1,600 m3 chilled water storage tanks in the Shenzhen Park, which store cold during the nighttime when the electricity rate is low and provide the cold source during daytime when the electricity rate peaks. The Company replaces the old equipment in the central air-conditioner room with energy-efficient cooling water towers, magnetic levitation units and intelligent frequency variable control equipment to realize intelligent control over circulating water pump and air handler, and accurately distribute cooling capacity and adjust water flow, therefore improving the energy efficiency ratio of air conditioning. The air-conditioning upgrade project under construction in Huizhou Park is expected to save about 260 MWh of electric energy per year and thus create a differential income of RMB 516,400.
Waste heat recoveryBy installing a heat recovery machine in the compressed air system and replacing the packing of the cooling tower, the Company improves the heat exchange efficiency and makes full use of the waste heat generated by the air compressor to provide hot water resources for staff dormitories, saving 1.5 million kWh of electricity each year.
Green culture constructionEmployees are trained on environmental protection knowledge and the eight wastes every year to strengthen the concept of green office and raise their awareness of energy saving. In 2023, the Company set up a joint inspection team to carry out the "21-Day Cost Saving Adoption Program". Specifically, the team checked the office cleanliness and savings weekly, and corrected unreasonable use of water, electricity, paper and other resources in the office. Promote green office and reduce resource waste. Paperless office was promoted as follows: Paper process exception forms and equipment maintenance records were replaced with electronic ones; hand towels at hand washing stations were removed, and handkerchiefs were distributed to employees; and a stationery sharing desk was set up to enable the cross-department circulation and recycling of office supplies and production consumables that are still in their lifecycle as evaluated. Optimize energy management to reduce energy consumption. In terms of air conditioning and lighting, the lighting in passages was replaced with LED energy-saving lamps controlled by human body-based light-sensitive switches; a system for the use of centralized and independent air conditioners was developed, with clear responsibilities and rules for switching on and off the air conditioners to reduce the waste. In 2023, the manufacturing and administrative departments carried out energy saving and consumption reduction program and 7S/5S office campaign, improving the energy use by 15% and 20%, respectively. Improve water usage in the office. Water saver faucets and sensor faucets were added; 125 barrel water dispensers were replaced with water purifiers in the Shenzhen Park; bottled water was replaced with tea for receiving guests to reduce water waste while effectively reducing the plastic waste from bottled water. New energy vehicles replaced fuel vehicles as routine transportation vehicles and commuter buses, and charging piles for new energy vehicles were installed in the park to encourage employees to travel in a green way.

Topband's Wastewater classification and treatment

Domestic wastewaterKitchen wastewaterIndustrial wastewater
It mainly involves toilet wastewater. It is discharged into the municipal pipeline network through the existing drainage pipes in the parks for treatment in the municipal wastewater treatment plant. A domestic wastewater treatment plant is built in the Topband Vietnam plant to discharge the domestic wastewater.It is filtered and then discharged into the drainage pipes in the industrial park.It is treated by a qualified third-party hazardous waste treatment agency for zero discharge of industrial wastewater. In Topband Mexico, the wastewater with some chemicals from the laboratory is first discharged into a special collection tank and then treated by a professional third-party agency.

Topband continuously strengthens the management of water resources through comprehensive and diversemeasures:

? Conduct water accounting or audits, analyze the water consumption based on the monthly meter readings, identify data discrepancies and resolve them in a timely manner. ? Train the employees on water compliance, so that they can differentiate between domestic and industrial wastewater and implement water conservation measures in production and life. ? In the process design, replace harmful materials with harmless ones, and prioritize chemicals that cause less environmental pollution when chemicals must be used. ? Install water-saving faucets in the hand-washing stations in the office area, and provide water-saving sprinklers and faucets in the dormitory rooms. ? Enforce rainwater and sewage diversion, and requires all departments to incorporate appropriate facilities for rainwater discharge into their programs for new, reconstruction and expansion projects.? Strictly investigate and deal with the behavior of mixing industrial wastewater and domestic wastewater, prohibit each department from dumping the oils and chemicals used and the hazardous waste liquids and residues generated (such as all kinds of wastes, soil and garbage) into the rainwater pipe network or flush them into the sewers. The departments in violation of the regulations will be imposed a disciplinary warning. ? Regularly clean the grease trap in the canteen to prevent wastewater with high oil content from being directly poured into the sewer without separation or treatment; provide filters at the sewage outlets in the canteen, and collect the filtered garbage as domestic waste. ? It is prohibited to place garbage in designated locations or areas to prevent the sewage from the garbage flowing into the storm drains during rainy days. ? It is forbidden to wash vehicles in the Company to avoid washing oil stains into rainwater or sewage pipes. ? Wipe up oil and chemicals dripping on the floor with a rag, and do not flush them with water into the sewers.
