Composts derived from mechanically segregated
MSW have several properties which may be of potential benefit for soil improvement
and restoration or in growing media, as well as a pre-treatment prior to landfill.
These are:
·
a limited (and slowly available) content of plant nutrients,
such as nitrogen, phosphorous, potassium, calcium, magnesium and trace elements
·
stabilised organic matter
·
a liming effect
·
biological activity.
Not all of these benefits are suitable for all
applications, see the Critical Review Section, End-uses.
However, composts derived from mechanically segregated
MSW also may have several properties which might be deleterious for these
