About Us

The Western Cape Industrial Symbiosis Programme (WISP) is a free facilitation service which uses industrial symbiosis to enhance business profitability and sustainability. The programme connects companies so that they can identify and realise the business opportunities enabled by using underutilised or residual resources (materials, expertise, logistics, capacity, energy and water). WISP is one of a number of Green Economy initiatives of the Western Cape Government, supporting the province’s intention to become the Green economic hub of South Africa and Africa.

WISP is delivered by GreenCape  and is fully funded by the Western Cape Department of Economic Development and Tourism (DEDAT). WISP works in collaboration with International Synergies Limited to deliver the programme as well as several government organisations and provincial departments including: The Department of Environmental Affairs and Development Planning (DEADP), The Western Cape Economic Development Partnership (EDP), The Cape Chamber of Commerce (CCOC), the National Cleaner Production Centre (NCPC) and The City of Cape Town (COCT).

WISP started in May 2013 as a pilot programme in order to address challenges around the continued viability of businesses, as the cost of energy and other inputs rise, impeding economic growth and job creation. The industrial symbiosis network now consists of over 300 companies and 3,000 resources have been identified within member companies. The data gathered for the synergies completed to date indicate that the following benefits have been achieved:

WISP continues to have a positive impact on businesses in the Western Cape, creating financial benefits for member companies, while also addressing the carbon intensity and resource efficiency of production processes. The diversity of the industries in which WISP operates, and the variety and size of its members, means that WISP has the potential to generate significant economic, environmental and social benefits from the synergies that it facilitates.
