The Quiznos on Foothill Blvd. in Hayward works hard to limit what it sends to the landfill by taking three-stream waste sorting seriously. Keeping recycling and organics out of the trash is one of the most effective ways a business can limit their burden on landfills, which are among the largest sources of greenhouse gas emissions across the globe.

Hayward’s Quiznos branch owner, Widi Gunawan, educates his employees and customers about proper waste sorting practices every chance he gets, acknowledging that it’s everyone’s responsibility to protect the environment. He received free waste sorting trainings from Waste Management of Alameda County, Inc. (WMAC), as well as sorting station stickers to serve as a visual reminder about what goes where.

Gunawan’s commitment to proper sorting is paying off, as the recycling and organic waste at his location has increased, while his trash volume has significantly reduced. Less trash means less waste ending up in the landfill, where the organics would degrade into harmful emissions. Proper sorting also means savings on Quiznos’ collection bills, as recycling and organics collection services through WMAC are each half the cost of trash collection services.
