On February 20, a presentation ceremony for the Hong Kong Awards for Environmental Excellence, also known as the “Oscar Award”in environmental protection in Hong Kong was held at the Hong Kong Convention and Exhibition Centre.

The Organic Resources Recovery Centre Phase 2 (O•PARK2) project designed, built and operated by CSCEC was awarded the gold award in construction industry. What’s more, the Kong Kong Tseung Kwan O Desalination Plant project and the Relocation of Sha Tin Sewage Treatment Works to Caverns project, which CSCEC has been involved in the construction, received certificates of merit.

Lauding the project team's efforts to achieve carbon neutrality during the construction of O•PARK2, Tse Chin-wan, Secretary for Environment and Ecology, HKSAR Government, expressed his gratitude to CSCEC for actively promoting the environmental protection and sustainable development of Hong Kong's construction industry.

O-PARK2 is the first certified Voluntary Emission Reduction project in Hong Kong that meets international standards. Upon completion, it will become the largest food waste recycling center in Hong Kong, and will also be the first green pilot project in China to achieve carbon neutrality within the construction period.

Gold Award •Hong Kong Awards for Environmental Excellence

Taking the highest rating of the Hong Kong green building environmental assessment certification as a design standard, the project adopts the Integrated Design Process (IDP), and promotes green building materials and renewable energy, with the carbon reduction potential of concrete blocks and low-carbon steel bars based on CCUS (Carbon Capture, Utilization and Storage) reaching 78% and 67%, respectively. The project also develops intelligent construction technologies such as BIM 7D, MiC, DfMA (Design for Manufacturing and Assembly), 3D printing, BIPV, and applies the C-SMART Integrated smart site management system and the Carbon Neutrality Cloud Platform and other digital management systems to improve the accuracy and efficiency of carbon accounting. The project combines the technologies for food-waste-to-energy to explore the whole lifecycle carbon negative transition during the construction period, with a carbon reduction efficiency of 24% during the construction period.

According to calculation and verification, by the end of June 2022, O•PARK2's total carbon emissions stood at 24,389 tons, achieving a carbon reduction of 4,240 tons, which exceeds the carbon neutrality commitment of 3,198 tons.

The Tseung Kwan O Desalination Plant, which received the certificate of merit, is the largest livelihood project undertaken by the Water Supplies Department (WSD) of the HKSAR Government with a Design, Build and Operate (DBO) integrated model. It is the most important project for the WSD in water resources management to enhance the resilience of fresh water supply. Once completed, the project will produce 135,000 cubic meters of potable water every day, accounting for about 5% of the daily potable water in Hong Kong.

The Tseung Kwan O Desalination Plant project adopts sustainable design and construction methods in all aspects. For example, the temporary site office building is built with MiC technology; the open channel and factory structure are constructed with DfMA prefabricated components; the electromechanical devices in the factory are assembled with the "Mechanical and Electrical Equipment Synthesis Method" (MiMEP). Such gestures have effectively shortened the construction period, strengthened quality control, improved project safety, and reduced consumption of building materials and carbon emissions.

Being the largest underground cavern project in Asia, the Relocation of Sha Tin Sewage Treatment Works to Caverns project will free up about 28 hectares of high-quality land and solve the aging of the existing sewage plant facilities and the impact on the surrounding environment. The project adopts MiC, DfMA, BIM and other construction technologies, applies an artificial intelligence weighbridge and a GPS system to strengthen waste management, as well as introduces solar technology to various project equipment to reduce carbon emissions.

Hong Kong Awards for Environmental Excellence, co-organized by the Hong Kong Environmental Campaign Committee and nine industrial, commercial and environmental organizations including the Hong Kong Environment and Ecology Bureau, is aimed at encouraging enterprises and organizations to implement environmental management, measuring the performance of organizations' environmental management commitments, and commending enterprises and organizations with outstanding performance in environmental management.
