Domestic garbage, or municipal solid waste (MSW), is garbage that includes organic material, recyclable material, electrical and electronic garbage (WEE) together with other garbage. Traditionally this garbage has been wholly and directly disposed in landfills. Recyclable domestic garbage on the other hand is that part of the domestic garbage that can be recycled and reused after the termination of the product function. Recyclable domestic garbage can typically be extracted from MSW in a material recovery facility (MRF). A clean, or dry, MRF is one that processes unsorted recyclable garbage that has already been separated at source from the non-recyclable garbage. Typically, such garbage consists of glass, ferrous and non-ferrous metals, plastics, paper and cardboard. The material is first sorted to meet the requirements of the plant, and then further processed (e.g. baled or compacted) for shipment to the applicable markets.
MRF performs the sorting of recyclable domestic garbage. STAVN always keep improving the technology of the MRF. Making the garbage sorting plant more efficient is our target that we pursue. One of MRFs is a dry MRF that receives about large tones of material per day. The unsorted garbage, known as commingled garbage, that comes to the facility contains material that is categorized into three main classes, these being the target materials, the non-target materials and the rejects. The target materials are those materials that the MRF is able to process and are sorted out into a number of different categories: polyethylene terephthalate (PET) clear, PET colour, high-density polyethylene (HDPE), low density polyethylene (LDPE), paper, cardboard, ferrous and non-ferrous metals. The nontarget materials are recyclable materials that this particular plant cannot process but that are still recyclable and therefore are still collected from households, such as polystyrene (PS), polypropylene (PP), tetrapak, milk cartons and jablo. The materials which should not be present in the received mix make up the reject materials class.
