PLATFORM

SYNERGie® is the most successful platform of its type. Users enter resources they have and want to identify cross-sector reuse opportunities.

In operation since 2009, SYNERGie® has hosted data on over 100,000 resources from companies in all sectors and all sizes to advance resource efficiency, reduce costs and supply risks, and improve sustainability.

ISL has incorporated its global experience in SYNERGie® through its ADVISOR function, a reference library to guide the user to reuse opportunities that have been successful elsewhere.
