“One of Europe’s greenest and most ambitious” freezers is set to be installed at ice cream maker Mackie’s family farm in Aberdeenshire, in a move designed to cut both costs and carbon emissions for the Scottish firm. Mackie’s, which produces ten million litres of ice cream a year, said it hoped to cut CO2 emissions by up to 80 per cent and drive down its energy costs by as much as 70-80 per cent once the new freezer is fully installed. Mackie’s new refrigeration system has been built to instead run on ammonia produced using hot water from a large biomass boiler on site, which it said would reduce temperatures to -15C with minimal electrical input. Conventional refrigeration compressors will reduce the temperature further to -30C if necessary, it explained. The new system is designed to freeze ice cream quicker than a conventional freezer, which it said would improve the quality of the end product while helping to increase production to meet growing demand.
