The Environment, Transport & Works Bureau wants to develop and operate a permanent grease trap waste treatment facility at the West Kowloon Transfer Station in Sham Shui Po.

In a Legislative Council paper today, the bureau said the project includes the design and construction of facilities for the reception, treatment, recovery and disposal of grease trap waste. One of the major benefits will be the recycling of the waste.

The waste unloaded from the collection tankers will be processed in a treatment system where the oil and grease will be concentrated into a semi-solid state which can then be recovered for reuse as an alternative industrial fuel, reducing reliance on fossil fuels.

The facility will recover 15 tonnes of oil and grease for reuse daily, which can be sold by the contractor on a commercial basis.

The estimated cost of the works is $85.3 million and are proposed to start in June for completion in May 2007. The bureau will seek funding approval from the Finance Committee in April. It will negotiate the contract terms with the West Kowloon Transfer Station contractor after funding approval, and is exploring the potential outlets for reusing the recovered oil and grease.
