The College Hill Association will host a collaborative program for the entire Pullman community called Pizza for the Planet. They are encouraging all households in Pullman to save their pizza boxes in April. They will be collecting the boxes in the Ruby Street Park (605 NE Colorado) on Earth Day, Saturday April 22nd from noon-4pm. The boxes will be converted to biochar, a sustainable soil additive that sequesters carbon and promotes soil health.
