General Motors has ramped up its composting efforts to every single floor of the automaker’s company headquarters, the Renaissance Center.
The campaign for composting started with select restaurants inside the RenCen, but each floor will now compost food scraps and waste. GM hopes it can further reduce its environmental impact with the latest move. The RenCen is also a landfill-free facility.
GM works with local composting startup Detroit Dirt to collect food scraps and fruit and vegetable pieces from the headquarters. From there, the startup company mixes the waste with herbivore manure to create nutrient-rich compost that is then used to cultivate urban gardens throughout the city. In fact, some of the same compost helps fruits and vegetables grow at the automaker’s Beaubien rooftop garden.
Things come full circle when food harvested from the RenCen rooftop garden is donated to a local restaurant, Andiamo Riverfront. The restaurant then makes donations to the local warming center serving the city’s homeless. The composting program collected more than 125,000 pounds of scraps in 2017.
