Envac was appointed as waste collection partner because of its strong record of adding technological and environmental value to the buildings and communities it serves.
Hong Kong Science & Technology Parks Corporation
The Hong Kong Science & Technology Park (HKSTP) is a sprawling 22-hectare waterfront ecosystem home to one of the world’s most state-of-the-art laboratories and research and development sites.
From robotics and precision engineering to renewable energy and pharmaceuticals, HKSTP has become globally renowned for attracting tech start-ups and innovative companies.
During the development stage, HKSTP was committed to making its buildings as technologically advanced as the companies that inhabited them and make the development a global showcase, which is why the board opted for an automated waste collection system (AWCS).
Following a competitive tender process, Envac was appointed as HKSTP’s waste collection partner in 2000 after demonstrating a breadth of global expertise and a strong record of adding technological and environmental value to the buildings and communities it serves.
Envac designed and installed a system that would become the first major office project in Hong Kong to incorporate AWCS across two waste streams, which includes mixed waste and paper.
The system was installed over multiple phases, with the first phase becoming operational in 2002. Now, over 15 years later, the system transports nine tonnes of general waste and 2.2 tonnes of paper from waste inlets placed throughout the entire site to a central collection station.
Now, in 2018, there is no evidence of traditional waste collection methods on-site and no overfull bins. Furthermore, as new buildings are created, the Envac system can simply be extended and connected up to the existing pipe network and collection station.
