It is necessary to consider the origin of the screening refusals, if it is about B or even C wood, it would be strongly inadvisable to carry out such a valuation
if it is wood A or green waste, this is formally possible, however the particle size of this fraction must also be considered which, depending on the grinder used and its setting, may be too coarse for this application; usually a grain size not exceeding 80 or even 90 mm can be used.
in addition, the presence frequently observed in this type of substrate of foreign bodies such as stones, ferrous or non-ferrous metals, light undesirables, plastics, etc. again prohibit this use.
in conclusion, these refusals have most of the time required to be refined by separators of the magnetic type for the FE fraction, ballistic for the stones, and aeraulic for the light undesirables, or even other processes, even also a regrinding if they are too coarse.
Hello, shredded wood can also be used as an underlay for odor treatment biofilters. But here too, it depends on the grain size, cleanliness and origin of the wood.
