Life cycle assessment of solid wood pallet
摘要
Abstract
China is one of the leading countries in production and consumption of pallets.Solid wood pallets dominate the market,contributing significantly to the sector's demand.However,this also leads to substantial annual consumption of imported wood,highlighting a critical reliance on external resources and raising concerns about sustainability and environmental impact.Therefore,the new automatic pallet production process and the use mode of"recycling and sharing"have been implemented and advocated in recent years to achieve material saving and high efficiency,but the effects need to be further evaluated.In this study,the material and energy consumption of solid wood pallets from raw material acquisition to end-of-life treatment were analyzed.The ReCiPe evaluation method was applied to evaluate the impacts of production process and usage pattern change on the environmental properties of pallets.The results showed that the life cycle stages of solid wood pallets,listed according to the environmental impacts from the highest to the lowest,were the acquisition of raw materials,the use of pallets,the production of pallets and the end of pallets.The raw material acquisition stage accounted for 87.2％of the environmental impacts of solid wood pallet,in which,marine transport and wood drying were the two processes that contributed the most to the environmental impacts,and the main environmental impacts were fossil depletion and climate change-human health.The power consumption of the automatic production of solid wood pallets was slightly higher than that of manual production,and the environmental impact was 5.63％higher than that of manual production.However,the automation process offered significant advantages in terms of improved production efficiency and the reduced labor requirements,making it a more cost-effective and efficient option overall despite the slight increase in environmental impact.Recycling and sharing significantly reduced the resource demand for raw materials and production stages through the recycling and maintenance of the pallets.The consumption of wood and steel nails in the automated production of solid wood pallets was reduced by 4.4％and 5.0％,respectively,compared to the one-way use mode.The environmental impacts of solid wood pallets were also reduced accordingly,and the reduction in the raw material acquisition and pallet production stages was as high as 95％,beneficial to the sustainable development of the pallet industry.关键词
