King County Executive Dow Constantine honored 92 local companies for reducing waste and increasing recycling, naming them as the county’s “Best Workplaces for Waste Prevention and Recycling for 2012.”

The sixth-annual list spans a wide array of businesses in King County, including hospitality, medical services, professional services, retail, finance, government, arts and entertainment and others. The list includes an honor roll for companies that have made the list at least five years in a row.

Bothell honorees are: AMEC Environment & Infrastructure, City of Bothell, Harmony Massage and In Harmony Sustainable Landscapes.

Last year, businesses in King County sent more than 180,000 tons of recyclable materials to the landfill. King County’s Solid Waste Division compiles the “Best Workplaces for Waste Prevention and Recycling” list annually to recognize the top recyclers and waste reducers, and help motivate others in the local business community.

All businesses operating in King County outside the city of Seattle are eligible for the list. To secure their spot, businesses are required to meet the same five basic criteria, as well as 10 additional waste-reduction and recycling criteria, such as using reusable or compostable dishware in kitchens, collecting batteries for recycling or sending electronic invoices.
