Changes to organic waste recycling rules this summer are set to impact some food businesses.

The city Sanitation Department is now mandating businesses with a floor area of at least 15,000 square feet, chain food service stores with 100 or more locations in the city, and retail food stores with a floor area of at least 25,000 square feet must separate organic waste from garbage. The new rules take effect on Aug. 15.

Organic waste usually includes vegetable and fruit debris, bones, eggshells, food-soiled paper, and garden waste.

Businesses already affected by the rules as of July 19, 2016 include food service establishments in hotels with 150 or more rooms, arenas and stadiums with a seating capacity of at least 15,000, food manufacturers with a floor area of at least 25,000 square feet, and food wholesalers with a floor area of at least 20,000 square feet.

Local Norwood eateries like Dunkin’ Donuts, Subway, and McDonald’s may be impacted by the added rules.

In 2003, the city passed its Commercial Organic Waste law requiring any businesses selling food to recycle their organic waste. Businesses that violate the law will be liable to a civil penalty amounting in $250 to $1,000 per violation.

General recycling requirements for metal, glass jars and bottles, rigid plastic, clean paper and cardboard cover all businesses regardless of establishment size or type, and items must never be mixed with garbage.
