Management of wood waste generated from construction activities can be a challenging task. Waste
wood is more often than not mixed with other materials, such as different metals, thermal insulations,
concrete or just plain dirt. The presence of any non-wood substance is greatly affecting the reusability
and recyclability of the waste. If not appropriately managed, the wood waste can be dangerous to humans
and the environment. The status quo is that wood waste is incinerated with or without energy recovery,
oftentimes with unsuitable cleaning. Therefore, one should take into account all wood waste generated
from construction activities and apply proper classification to minimize the environmental impact and
improve decision making. The purpose of this study is threefold: to extract data about the actual wood
waste, to compare these data with the bill of materials (BoM) of the life cycle assessment (LCA) and to
develop ideas on future reusability of collected wood waste.
Woodwaste generated from the construction sitewas collected, measured, classified and sorted manually.
The majority of the wood waste was quantified volumetrically by measuring all three dimensions of each
specimen; however, smaller residues were measured using a scale. All wood collected was grouped into
three categories based on the type of wood and further into eight sub-categories based on the type of
contaminants that were present.
Data collected was analysed and was compared to results from the BoM of the building. Wood reused
at the building site made a direct comparison difficult. However, a significant amount of reusable and
also recyclable wood waste from the construction site has been prevented from incineration. Proper
wood waste management plays a significant role in reducing the adverse effect that wood waste from
construction can have on the environment and allowing for more sustainable construction.
