Looking like a souped-up dumpster with a Holstein theme, ReGenerate’s Compact Organic Waste Station (or COWS) creates compost and energy from what would otherwise be wasted in a landfill. The COWS unit is an anaerobic digester and functions in a similar way to a cow’s stomach, breaking down food scraps and generating a methane biogas that’s then redirected to heat water on site. When used at capacity by a hotel, cafeteria, or supermarket, the COWS system can save as many as 100 tons of organic waste from ending up in landfills. With hauling prices and tipping fees steadily rising in recent years, alternatives like COWS are not only greener but also more economical.
