Kraft creates energy from cheese waste

I never thought Kraft had the most healthful food selection, but I’m at least glad to hear that they’ve found another use for their food waste. Two of their cheese plants are now responsible for turning whey into biogas.

“Our facilities have previously used strategies such as concentrating the whey to reduce volume and finding outlets for it to be used as animal feed, or for fertilizer on environmentally approved farm fields,” said Sustainability Vice President Steve Yucknut. “Both methods required transporting the whey off-site. Now, we’re reducing the associated CO2 emissions that are part of transporting waste, discharging cleaner wastewater from our on-site treatment systems, and creating enough alternative energy to heat more than 2,600 homes in the Northeast.”
