Finnish renewable fuel and chemicals firm Neste will be collecting Christmas ham fat waste to produce its renewable diesel for the fourth year in a row as part of its annual Kinkkutemppu (Ham Trick) campaign.

“Last year, 185,000 Finnish households participated in the Ham Trick,” the company said on 26 November. “The goal for this year is to increase the number of participants to 200,000.”

Neste would use the collected ham fat waste and other waste fats at its Porvoo refinery to produce its MY Renewable Diesel, adding that it had recycled more than 100 tonnes of waste fats in the past three Christmas seasons through its Ham Trick campaign.

Consumers could take part by delivering their waste fats to collection points around the country between 21 December to 7 January.

Neste said its Ham Trick campaign was a cooperative project initiated by the Chemical Industry Federation, which aimed to familiarise consumers with the principles of a circular economy.
