Avfallsstrømmen

Avfallsstrømmen, a Norwegian term for the waste stream, refers to the total flow of waste materials generated by households, industry, commerce, and institutions as they move through collection, transport, sorting, treatment and final disposition. It encompasses several waste streams, including municipal solid waste, construction and demolition waste, industrial waste and hazardous waste, and covers both organic and inorganic fractions.

The composition and size of avfallsstrømmen vary by country, sector and economic activity. Household waste often dominates urban streams, while industrial and construction waste can be substantial in other areas. A significant portion may be hazardous or require special handling, such as batteries, electronic waste, chemicals, and heavy metals; informal handling can occur in some regions.

Management of the avfallsstrømmen typically involves sourcing separation, collection systems, and treatment facilities. Key options include recycling and material recovery, composting and anaerobic digestion for organics, energy recovery by waste-to-energy plants and incineration, and landfilling as a last resort. Integrated management aims to reduce environmental impact and conserve resources within a circular economy framework.

Policies and regulations define responsibilities, set targets, and encourage waste prevention. Common instruments include extended producer responsibility, pay-as-you-throw schemes, quotas for recycling, and reporting requirements. Proper management reduces pollution, greenhouse gas emissions, leachate risk, and resource depletion.

Monitoring of the avfallsstrømmen relies on metrics such as generation rate, recycling rate, energy recovery, and landfill diversion, typically reported at national or municipal levels. Data inform planning, investment, and policy design to improve sustainability of waste systems.
