Here’s a breakfast that’s capable of not only fueling your body but also powering the entire factory that makes it. Scott’s Porage Oats, a Quaker Oats Factory at Uthrogle Mills in Scotland is installing a combined heat and power biomass boiler that will enable the factory to become carbon-neutral, running entirely on waste oat husks. The husks, removed from the oats during the milling process, will provide 9,709 MWhrs of electricity and 10,902 MWhrs of steam a year, reducing its emissions by 9,000 tonnes a year—equivalent to the annual emissions of 3,000 cars. Now none of the energy stored in the oats will go to waste.
The $12 million boiler (about five times more expensive than the fossil-fuel model) will make this factory one of Scottland’s greenest. During the first three years, more than 1,300 MWhrs of renewable energy will be exported to the National Grid. Quaker also estimates that they will cut over 172,000 miles in transportation every year since the factory will no longer have to remove 21,150 tonnes of husks—reducing their emissions by another 600 tonnes a year.
