Composting is a process that involves (1) taking food and yard waste and mixing it with a bulking agent like sawdust, (2) letting the mixture decompose and rot, and (3) creating beneficial mulch that can be used as fertilizer in gardens. It is important to follow the recommended 1/2 waste to 1/2 bulking agent recipe to prevent bugs and smells, and to wear gloves and wash hands when working with compost.
