The Ham trick (kinkkutemppu in Finnish) is a consumer campaign organised in 2016 and 2017 in Finland during the Christmas period.

This cross-sectoral co-operation with Finnish companies and organisations aimed at bringing the concept of circular economy closer to consumers,  advising about recycling and avoiding that the drains were choked by excess fat at Christmas.

ECO3 is an innovative, industrial-scale, multidisciplinary bio- and circular economy business area. It offers companies which set up there a number of advantages, such as expert assistance in developing the circular economy as a core business concept, support with finding business and cooperation partners and frictionless cooperation and teamwork with public administration and authorities.
