Yard waste includes grass clippings, leaves, branches, garden trimmings, and other organic materials from residential landscaping. Many municipalities collect yard waste separately from garbage for composting rather than landfilling. Collection programs may use dedicated bins, seasonal leaf collection, or depot drop-off. Composted yard waste becomes soil amendment products. Yard waste diversion reduces landfill use and avoids methane emissions from decomposing organics. Some municipalities encourage grasscycling—leaving clippings on lawns—and backyard composting to reduce collection needs. Yard waste programs typically have seasonal variations, with heavy volumes in spring and fall. Branch and tree debris may require separate collection or chipping programs. Yard waste programs contribute significantly to municipal waste diversion rates.
