A complete natural resource, this noble material sees every part of itself employed in surprisingly versatile ways. Wood is a recyclable material par excellence, which plays a fundamental role in the fight against climate change because of its ability to absorb carbon dioxide. The recycling of wood at the end of life allows then to “freeze” the stored carbon dioxide, thus avoiding the release into the atmosphere of millions of tons of CO2 compared to other uses, such as waste to energy.
Every year millions of tonnes of wood are disposed of for all sorts of reasons. Only about 15% of waste wood is recycled across the world and that 9 billion m³ of underbark (inner layer of tree bark) is removed from global forests annually, almost half (49%) of this underbark is used as wood fuel – the rest is for industrial roundwood (used by wood processors).
Urban waste wood is increasingly recycled to be used for the production of wood-based panels or other applications, for which the removal of metal contaminants is crucial.
Wood recycling technologies
From the experience of working closely with the Italian wood-based panel industry, SGM has developed a complete range of specific separators for removing both ferrous and nonferrous metal contaminants during the different stages of the urban waste wood recycling process, either when urban wood waste is still raw or further down the process when it has been transformed into chips and flakes before passing to the panel press.
SGM has extended its experience to many other international urban wood waste recyclers and is a technology leader in this field with a complete range of
- magnetic ferrous separators,
- eddy current separators,
- induction sensor based sorters,
- air gravity tables.
As per your request, the SGM separator can be designed to meet ATEX requirements.
