The global demand for sustainable building materials has fuelled research into composite panels from wood waste. Despite their potential, the widespread adoption of this practice is hindered by the absence of quality standards, inconsistent material properties, and uncertainties about durability and strength. This paper critically reviews existing standards, manufacturing processes, and the suitability of panels from wood waste. A systematic review is conducted to identify the influencing processes and parameters affecting panel performance, from waste collection to the finishing stages. The findings indicate that incorporating 10–30% of wood waste can enhance the mechanical and physical properties, with particularly improved hygroscopic properties and greater dimensional stability. By establishing comprehensive standards and optimizing manufacturing processes, wood waste-based panels can emerge as a viable and eco-friendly alternative. Furthermore, the potential for repeated recycling in a closed-loop process offers promising environmental benefits, though it necessitates balancing resource conservation with product quality. By addressing these challenges, wood waste-based panels can significantly contribute to environmental conservation and resource management.

Engineered wood products (EWPs) and timber buildings are increasingly recognised for their potential to reduce greenhouse gas emissions by storing biogenic carbon and replacing emission-intensive materials. This article systematically evaluates the carbon footprint (CF) of EWPs and timber buildings during the production stage (A1–A3), identifies key sources of variability, and extracts quantitative emission reduction metrics. Based on a review of 63 peer-reviewed studies, CF values vary widely, from −40 to 1050 kg CO₂eq m⁻² for buildings and 12 to 759 kg CO₂eq m⁻³ for EWPs, due to inconsistent system boundaries, functional units, and emission factor assumptions. Median CFs were 165.5 kg CO₂eq m⁻² and 169.3 kg CO₂eq m⁻³, respectively. Raw material extraction (50.7%), manufacturing (37.1%), and transport (12.2%) were the dominant contributors. A mitigation matrix was developed, showing potential reductions: 20% via transport optimisation, 24–28% through low-density timber, 76% from renewable energy, 11% via sawmill efficiency, 75% through air drying, and up to 92% with reclaimed timber. The geographic skew toward Europe and North America underscores the need for region-specific data. The findings provide actionable benchmarks and strategies to support carbon accounting, emissions modelling, and climate policy for more sustainable construction.

Engineered wood products are widely promoted as climate mitigation options in the building sector, yet their assessment remains dominated by static life cycle metrics that aggregate emissions and removals over fixed time horizons. Such approaches obscure the temporal separation between rapid industrial emissions and delayed biogenic carbon uptake in forest–wood product systems. Here, we develop a dynamic carbon accounting framework that tracks anthropogenic emissions and biogenic carbon flows on a common time axis across forest growth, harvesting, and engineered wood product manufacturing. Applied to an Australian plantation-to-cross-laminated timber supply chain, the analysis reveals a robust and counter-intuitive result: carbon payback occurs within approximately 11–12 years despite substantial variation in manufacturing-stage emissions. This indicates that forest regrowth dynamics govern the timing of carbon parity, while manufacturing-stage mitigation primarily influences longer-term cumulative outcomes. Dynamic carbon accounting therefore complements static assessment by clarifying when climate benefits occur under time-bound decarbonisation goals.
