The Group's primary air pollutant emissions come from the use of boilers in the operating management business and the use of automobiles in subsidiaries of various businesses. Huanggu Thermoelectricity strictly complies with the requirements of the Coal-fired Power Plant Ultra-Low Emission Retrofit Plan of Lianoing Province and the Notice of the Environmental Protection Department of Liaoning Province on Coal-fired Power Plant Ultra-Low Emission Retrofit Plan and has completed all ultra-low emissions retrofits. Our measures include:
The Gorup's non-hazardous waste mainly includes construction waste from facade contracting engineering business, fly ash, slag, and desulphurized gypsum from Huanggu Thermoelectricity under the investing and operating business and other waste from the production process, as well as general office and domestic waste. The hazardous waste mainly includes electronic products, waste lamps, waste batteries, waste cartridges and used oil from the manufacturing and office processes. The Group has strictly managed the waste disposal to ensure the waste is properly and appropriately disposed of and adopted various measures to reduce the negative impact of waste on environment.
To reduce the emission of non-hazardous waste, the Group has implemented various measures, including reducing paper consumption, promoting the online document management, e-stamping and electronic file library system, and encouraging staff to sort and recycle.
| Through these steps, the Group has successfully obtained the Wastewi$e Certificate (Good Level) certified by the Hong Kong Green Organization. |  |
The Group's major wastewater includes the flue gas desulphurization wastewater and domestic sewage from the investing and operating management business. In addition to strictly comply with laws and regulations such as "Integrated Wastewater Discharge Standard", the Group also closely monitors sewage discharge through the following measures:
The Group has published the Green Office Guidelines and advocated various initiatives regarding the proper use of water resources. Huanggu Thermoelectricity implemented a water conservation system, planning to transform the steam heating to water heating. At the same time, it is proposed to use the water discharged from the primary network to rinse the secondary network, to minimize the amount of water used in rinsing the secondary network of the heat network. We have also further reduced water consumption through reclaimed water recycling projects, which can reduce water consumption by 50 tonnes per hour and 181,200 tonnes for the whole winter heating season.
The Group's energy consumption mainly comes from the use of electricity and fossil fuel combustion. In this regard, the Group requires all subsidiaries to establish and improve the energy management system in accordance with the law considering the actual situation.
Far East Zhuhai has introduced into its facade composition an internal circulation and ventilation system, which can improve a building's overall thermal performance by controlling wind flow direction and volume. It can facilitate curtain walls' heat dissipation and prevent them from frosting under cold weather conditions, thereby reducing their demand for energy.

| As early as 1997, Huanggu Thermoelectricity took the lead in retrofitting the water circulation heating, which could offer water circulation heating in winter. On average, 300,000 GJ of residual heat are recovered per heating season, with an estimated average annual saving of 12,000 tonnes of standard coal. | In 2014, Huanggu Thermoelectricity retrofitted the water circulation system of boilers with the energy management contract mechanism and installed two lithium bromide absorption heat pump units with a heat production capacity of 19.15 MW to recover the waste heat of the circulating water. On average, 160,000 GJ of residual heat is recovered per heating season per year, with an estimated saving of approximately 6,240 tonnes of standard coal. | In 2023, 13 high energy-consuming transformers and 21 convertors were replaced, which is estimated to save 194,100 kWh and 366,800 kWh of electricity per year respectively. | After a trial lasting almost two months in 2021, the project achieved prominent results in saving energy, reducing consumption, and enhancing heat supply quality. In 2022, the technical transformation of hydraulic balance of secondary network covered an area of 1.6 million square meters, thus realizing energy saving and consumption reduction through raising the heat supply efficiency of heat exchange stations and cutting heating consumption and electricity consumption by 2-4.5% and 3-10% respectively. In 2023, 1.5 million square meters of secondary network were further upgraded. | In 2022, after the completion of the ACS system retrofitting of boilers 6 and 7 in the factory, 4% of coal and 2% of the electricity were saved. On average, 942 tonnes of standard coal can be saved per one heating season. |
Through driving technological innovation, setting up relevant departments and taskforces, and investing in renewable energy, the Group actively responds to the carbon reduction actions and goals of the places where it operates, thus integrating into the sustainability blueprints of these places.
The Group has formulated and implemented the "Green Office Environmental Proposal” and the “Green Office Guidelines" covering different aspects such as encouraging paperless office, keeping the temperature of air-conditioning above 25°C in summer, replacing business trips with video conferences, and advocating green travel.
The Group was awarded the "Green Office" and "Eco-Healthy Workplace" labels from the World Green Organization for consecutive years
The Group organized a green hiking. Through hiking activities, we promote the importance of health, exercise, and environmental conservation.
To fulfil our responsibility to protect and beautify the environment, our Group organizes the employees to partake in volunteer activities such as garbage cleaning and environment preserving every year. The Group organized our colleagues to volunteer for environmental protection, putting into practice our bright vision of developing our corporate and ecology at a harmonic pace.
"Turing Trash into Treasure", which promotes the philosophy of reusing the remaining materials, such as aluminum profiles, from the production to build guard post, temporary quarantine room, office, office equipment, event props, etc. that are unique to enterprises through splicing and transforming those material remainders by production workers. We hope to raise employees' awareness of environmental conservation.
To cultivate the recycling habits of our employees and exercise environmental concepts into real-life practices, we organized various recycling activities. For example, recycling day events were held to educate employees about the importance of proper waste separation and recycling, and a fun upcycling workshop to make handcrafts from recycled glass cullet.
