Efforts by students at Sun Valley Elementary School in San Rafael to push a company to give consumers a way to recycle felt-tip markers has paid unexpected dividends.
Earlier this year about 40 students and their volunteer adviser launched “Crayola: Make Your Mark!” — a campaign via Change.org to prod the Crayola Co. of Easton, Pa. to start a recycling program for used markers. More than 80,000 people across the country signed the petition.
