Matavfallet

Matavfallet is the definite form of the Swedish term matavfall, referring to the food waste fraction of municipal solid waste. It comprises organic material from kitchens and dining tables that should be separated from other waste streams. Typical constituents include fruit and vegetable scraps, bread, grains, coffee grounds, tea bags, eggshells, and dairy products. In some jurisdictions, meat, fish, bones, or fats may be allowed in matavfallet if the local waste system supports it; in others these items must be handled separately.

Sorting at source is common in many municipalities, with households using dedicated bins or bags for matavfallet. The collected material is transported to facilities for processing, which may include anaerobic digestion or aerobic composting, depending on local infrastructure and regulations. The packaging and contamination rules for matavfallet are highly jurisdiction-specific.

Treatment of matavfallet yields environmental benefits. In anaerobic digestion, the waste is converted into biogas, which can be used for electricity, heat, or upgraded to renewable natural gas, while digestate serves as a nutrient-rich soil amendment. In composting, the product is compost that enriches soil. Diverting matavfallet from landfills reduces methane emissions and supports nutrient recycling within a circular economy.

Programs for matavfallet face challenges such as odor, pests, and contamination with non-organic materials. Public guidance often emphasizes rinsing or draining liquids, removing packaging, and following local rules to maximize recycling and energy recovery.
