In addition, it is produced from parts of trees that are unsuitable for other industries, such as plywood or laminated timber, thus maximizing the use of trees. However, the woodworking sector in Spain faces a number of challenges that need to be addressed: - Cover the harmful effects of volatile organic compounds emitted during wood processing - Reduce energy consumption - Consider social risks such as job loss, apart from health and safety issues, particularly related to toxic risks Therefore, the objective of this study was to analyze the level of sustainability, including environmental, social and economic dimensions, of an LSL production system in Spain.
