Future uses for wood waste

The last step in the wood recycling process is the sale of materials. What becomes of waste after it is collected, sorted and shredded? Which recovery channels does it usually join? Who uses recycled sawdust in France? Here are some answers to these questions.

Wood-based panel manufacturers

Wood-based panel manufacturers

Wood-based panel manufacturers make the wood panels used by the manufacturers of furniture and materials used in shop fitting or construction.
 
They are transformers of raw materials and the number one users of the products sold by wood recycling companies: they use them to make chipboard (i.e. a material made of various chemically bound fibres) and favour class B and AB recyclable wood for this purpose.
 
These classes of wood are initially virtually untreated, and are sorted and shredded in wood recycling factories. 

Energy recovery

Energy recovery

In this instance, class A recycled wood (from the recycling of pallets, for example) becomes dendroenergy, which is the main energy resource produced from terrestrial biomass (and the number one renewable energy source used in France).
 
It is used – after leaving wood recycling factories – as a fuel to feed industrial or public authority boilers and heat networks.
 
In some cases, wood recycling also results in power generation, as it heats water to produce steam which in turn powers some generators. And when these boilers also produce heat, this is referred to as cogeneration (or combined heat and power). 

Other sub-sectors

While wood recycling specialists mainly supply dendroenergy or raw materials to industrial wood-based panel manufacturers, other minority sectors also need the materials collected, sorted and shredded by wood recycling companies.
 
 
Some landscape architects and arborists buy class A wood to make mulching (the organic material used to protect cultivated ground), cement manufacturers buy sawdust which they heat to power their ovens, pellet manufactures use recycled waste wood to make new combustible pellets, and some light wood shavings supplied by wood recycling specialists might ultimately become, after transformation, litter for animals.
