Agrivert design and build superstructure Facility in Hong Kong

One of the world's most significant investments for an organic waste treatment facility, this recycling facility will receive and process 300 tonnes of food waste per day. In addition, the Facility will produce over 45 GWh of electricity annually by capturing the methane contained in waste food - enough renewable energy to reduce Greenhouse Gases by 67,000 tonnes yearly. The development site is located on 2.5 hectares near Sha Ling, in Hong Kong's northernmost district.

Agrivert design and build superstructure Facility in Hong Kong

Hong Kong's landfills are being filled at an alarming rate. The city produces 5.67 million tonnes per year of municipal solid waste (MSW), of which food waste has been identified as a significant contributor. Only one-third of the waste is recycled, resulting in significant amounts deposited into Hong Kong's three large landfills. This Facility will divert significant volumes of organic waste away from landfill.

Hong Kong is one of Asia's most densely populated regions, with over seven million people living on just 1,106 square kilometres. The territory's rapid population and economic growth, coupled with limited waste treatment infrastructure, have resulted in the need for a new approach to waste disposal.

The Environmental Protection Department (EPD), a department of the Government of Hong Kong, set out a policy for managing Municipal Solid Waste. These establish a long-term goal to move away from landfills by providing sufficient waste-to-energy facilities to process the current and growing waste demand. Accordingly, EPD tendered for contractors to design and build an organic waste treatment facility that can treat 300 tonnes of organic waste daily through anaerobic digestion and operate that Facility for 15 years before handing it back to the government.

Agrivert won this tender and is now the lead joint venture partner contracted to design, build and operate this food waste anaerobic digestion facility known as "O·PARK2". The development is on target to move into operations in late 2023.

Once finished, O·PARK2 will operate 24/7 and be available for waste deliveries 7-days a week.

The Facility has been designed to be energy efficient, minimise energy consumption and export surplus energy to the public electricity grid. Combined Heat and Power (CHP) units will use the biogas generated by the anaerobic digestion process to generate heat for process use and electricity to power the Facility. As the quantity and quality of food waste deliveries are expected to vary – the treatment processes will be designed to treat changing volumes and rates of organic waste.

The residue from the anaerobic digestion process will be converted into solid, granulate fertiliser as a by-product for landscaping and agricultural application.

O·PARK2 has been designed to blend harmoniously with the surroundings. It is important that the Facility produces the least visual impact on the passing traffic and nearby communities.

Agrivert has partnered with Hong Kong-based specialists, Alchmex and JEC to deliver this complex project through a Joint Venture structure, which Agrivert leads.

Agrivert

Agrivert has primary responsibility for the design of the whole process plant and is the principal designer for the waste reception building, anaerobic digestion systems and fertiliser production through granulation. In addition, Agrivert will provide operational expertise and oversight for 15 years once the construction and commissioning are complete.

With nearly 30 years of experience, Agrivert is widely recognised as a leader in engineering and operating bio-waste treatment and renewable energy infrastructures that offer high efficiency, operability, and robustness. Agrivert designs, builds, operates and maintains best-in-class, award-winning infrastructure and provides advanced technical services to monitor and optimise assets, maximising efficiency and minimising downtime.
