(Vancouver, WA) -- Local officials are reminding residents not to throw their pumpkins in the trash after Halloween. Clark County Public Health says around 60 percent of pumpkins go in the garbage and end up in landfills, where they produce methane. You can toast the pumpkin seeds as a snack, or turn it into a puree to use in fall recipes. You can recycle a pumpkin in a yard debris waste bin or cut it into small pieces and turn them into compost for your garden.
