Central Farm Markets is launching a food recycling and composting program geared at encouraging kids to take up the practice.

Starting Saturday, June 22 and continuing each week through Sunday, Sept. 1, Central Farm Markets and the CompostCrew representatives at its Bethesda and North Bethesda markets will offer treats for each canister of compost a child brings in.

Kids age 5-16 who want to participate will sign up and pick up a canister. Each child will get a card with ten punch-holes and information on what sorts of items to put in the canister each week. Three “punches” will earn participants a free t-shirt. Those who get all 10 punches by Sept. 1 will get a bag of compost for their gardens and a gift card to Staples for school supplies.

The market takes place each Saturday from 9 a.m. to 2 p.m. at Mid-Pike Plaza (11806 Rockville Pike) and each Sunday from 9 a.m. to 1 p.m. at Bethesda Elementary School (7600 Arlington Rd.)
