LEWISTON — The 11th annual Clean Sweep, Bates College’s green “garage sale” of appliances, furniture, electronics and other goods donated by departing students, raised $16,540 in proceeds that will be divided among 13 local nonprofit organizations.

A community tradition, the June 18 sale filled the college’s Underhill Arena, drawing some 800 bargain-hunters from Lewiston-Auburn and the region.

Sale proceeds help support nonprofits that, in exchange, supply volunteers to help staff the event, as well as other logistical support. How large a share of proceeds each nonprofit receives is determined by the number of volunteer hours, trucks and tables it provides.

This year’s volunteers put in nearly 1,200 person-hours of effort, said Julie Rosenbach, sustainability coordinator at Bates.

Located in Lewiston except as indicated, the nonprofits taking part this year were: the Caleb Garden Club; Common Ties Mental Health Services; First Universalist Church, Auburn; the Justice, Ecology and Democracy Collective, Greene; Life Center; Lots to Gardens; Maine Fair Trade Campaign; Maine People’s Alliance; New Beginnings, Inc.; the Share Center, Auburn; Somali Bantu Community Association; Tri-County Mental Health Services; and the Trinity Jubilee Center.
