PepsiCo Brazil uses oat hull waste for on-site heating

PepsiCo, owner of the Quaker Oats brand, is using oat hull waste to heat a processing plant in Porto Alegre, Brazil.

Oat hulls, the outer shells of oat grains, are a by-product of oat processing and are plentiful at the Quaker Porto Alegre plant, which produces on average about 520 tons a month.

The facility now uses 1,440 tons of oat hull waste per year to fuel the facility’s biomass boiler. The remainder is ground, packaged and sold as livestock feed.

The conversion to biomass for steam production has produced thousands of dollars in annual savings, and reduced the plant’s energy consumption and greenhouse gas emissions, Pepsi says.

The Porto Alegre biomass fuel programme has resulted in a 41% reduction in total energy use.
