Timber Waste Minimisation by Design

WithMaria Elena Santana

Wood competes with other materials and products for many building applications from structural framing to cladding, because of its relatively low ecological impacts. Excessive waste occurs at all stages of the timber resource stream: growing, extracting, transporting, processing, using and disposing. Timber offers a variety of benefits in buildings and products due to its high strength, good thermal, acoustic and aesthetic properties, and its versatility and workability. The usage stage in the life cycle of timber building products involves installation, maintenance and chemical use. Wastage during installation is the most significant stage where designers can minimise timber waste considerably, as it is directly related to the design process. The ecological implications associated with the procurement of wood for building products are very significant, and depend primarily on the source of extraction: native forests or plantation forests. Timber converted into building products performs relatively well in terms of energy consumption and carbon emissions, when compared with other building materials.
