Black & Veatch awarded owner's engineer contract for Hong Kong biochar pilot
Hong Kong is increasing the recycling rate of yard waste and wood waste to promote sustainability. The Environmental Protection Department (EPD) has awarded global engineering firm Black & Veatch (B&V) with a consultancy service agreement to assess environmental engineering techniques for the city’s first woody waste recycling plant. The pilot plant will have a capacity of 24 tonnes-per-day and will be constructed in EcoPark, Tuen Mun.
Reducing waste is one of Hong Kong’s strategies to optimize resources and reduce landfill disposal while supporting sustainability. Woody waste recycling is a core element of the city’s bio-waste management strategy to divert valuable biomass resources from landfills.
Black & Veatch is ready to support Hong Kong’s sustainability visions. We have worked with a large number of utilities and government agencies on waste-to-energy projects throughout the world, and many of them involve the conversion of biomass by means of pyrolysis or gasification to energy products, said Andy Kwok, Managing Director, Black & Veatch Asia North.
Black & Veatch Hong Kong is tasked to review the technology, market, environmental, and regulatory aspects of the project’s proposed biochar plant. It is responsible for preparing a reference design, assisting in procurement, supervising construction and commissioning, and overseeing the pilot testing.
Biochar is similar to charcoal and made by using a biomass pyrolysis process. Biochar improves soil fertility and captures and stores carbon dioxide (CO2) safely. In addition, the pilot plant project will explore if biochar can be produced to meet higher quality standards for other beneficial uses.
The unique aspect of this pilot project is its focus on the production of biochar-type products, which are expected to find sustainable outlets in the Hong Kong market, said James Chan, Project Director, Black & Veatch Hong Kong.
For Hong Kong’s woody waste recycling plant, the potential feedstock includes used pallets, yard wastes as well as spent bamboo scaffolds.
