About us

International Synergies Limited (ISL) was established in 2005 and is widely acknowledged for its expertise in devising and managing industrial symbiosis programmes across six continents working with public and private sector clients, institutions and the research community.

ISL is the world’s leading expert on industrial symbiosis, recognised by the UN, G7, EU, Global Green Growth Forum and the OECD through its award-winning flagship programme and international brand NISP®. The European Commission cites industrial symbiosis as an innovative means to achieve resource efficiency: calling for Europe-wide implementation of industrial symbiosis as part of its ‘Roadmap to a Resource Efficient Europe’, the high-level ‘European Resource Efficiency Platform’ (EREP) and the 2020 Circular Economy Action Plan. In 2018 industrial symbiosis was entered into European Law via amendments to the Waste Framework Directive. In addition, industrial symbiosis is acknowledged by the UN’s International Resource Panel (IRP) to support all SDGs through resource efficiency.  In the UK industrial symbiosis is a key pillar of the Industrial Decarbonisation Strategy published by BEIS in March 2021 and also is part of the Defra Waste Prevention Programme as identified in its March 2021 consultation.

ISL provides through consultancy expertise and facilitation (to private companies and public sector alike) including capacity building and training to enable others to implement industrial symbiosis projects at local, regional or national level.
