On the 9th of September Jörgen Held visited Rönneholm waste management facility outside Eslöv, Sweden. At the Rönneholm landfill two Stirling engines are used to produce heat and power.

The two Stirling engines were installed in 2012. The capacity is 7 kW power per Stirling engine. Notice that there is no need for ear protection when the Stirling engines are running. In fact it was possible to have a normal conversation.
While normal spark ignited gas engines need landfill gas with a methane content of about 40% the Stirling engines are able to operate down to ~15-20%.
