  1. MRFs and municipal waste-bold success or heroic failure ?

    Article - En anglais

    Material reclamation facility, or MRF, was a name originally coined in the USA to descrive the variety of sorting facilities developed in an attempt to cope with the vast increase in municipal rubbish from the 1970s onwards.

    Based on agricultural and mining sorting and grading equipment, some of these facilities have evolved into sophisticated machinery systems requiring elaborate design and considerable investment from the responsible municipality or its contractor.

    Municipal waste is typically high volume and low value.

    It contains a large percentage of organic waste and some hazardous items and materials, such as household cleaners and discarded syringe needles.

    The extraction of potentially saleable recyclates from such material is the purpose of MRFs and the general principles of managing this process are discussed.

    Recycling is generally placed second only to reuse in the hierarchy of waste management.

    To maintain this position will, as the life cycle analysis of waste materials becomes more intensive and thorough, largely depend on the efficiency of the MRF and, crucially, the collection system that feeds it.

    The position of the MRF within the waste management system is discussed.

    Ultimately, MRFs must be considered a temporary measure to allow some material recovery while the whole nature of material flows in society is readjusted to ensure that nothing of recycling value ends up as waste. (...)
