Haveaffald

Haveaffald is a Danish term for garden waste, referring to plant-derived materials generated in private gardens, parks, or landscaping activities. It covers grass clippings, leaves, hedge and shrub trimmings, small branches, twigs, spent or dead plants, and often mulch or soil that comes from garden work. It is distinct from household non-organic waste and from bulk waste that requires special handling; exact inclusions can vary by municipality.

Typical contents and exclusions can vary, but haveaffald generally comprises plant material that is compostable or suitable for mulching. Large quantities of soil, contaminated soil, stones, or treated wood are usually handled separately or require special disposal. Some facilities also distinguish between healthy garden vegetation and invasive species or diseased plants, which may need different treatment.

Disposal and collection systems in Denmark often include curbside green-waste bins and dedicated green-waste containers, as well as local genbrugsstationer (recycling centers) where haveaffald can be delivered. Municipal programs may set limits on size, weight, or volume. Processed haveaffald is typically transformed into compost or mulch; some portions may be anaerobically digested to produce biogas and digestate used as fertilizer.

Home handling and best practices include composting garden waste at home or using it as mulch, with attention to creating a balanced mix of carbon-rich and nitrogen-rich materials, adequate moisture, and good aeration. Avoid disposing of diseased plants, invasive species, or heavily contaminated material in home composts. Following local guidelines for sorting and disposal helps reduce landfill use and supports nutrient recycling.
