At the Hong Kong Eco Park  a number of recycling firms co-exist side-by-side on a 20 hectares plot. The companies recycle a variety of waste materials such as cooking oils, wood, metals, electronics, plastics and batteries.

The Eco-Park is part eco-industrial centre and part recycling centre, with waste only being used for waste-conversion feedstocks and inputs for manufacturing. The varying companies don’t, however, involve exchanges of material or energy, but do share various other human and infrastructure resources to draw down environmental impacts.
