Cascading Recovered Wood
Abstract
Wood products at the end of a life cycle are invariably chipped into particles. The two main end-uses for the recovered wood (RW) are particleboard manufacture and energy generation. The CaReWood project will develop and evaluate techniques for converting large dimension RW into new, large dimension solid wood products to complement the solid wood currently used in the furniture, interior fitting and construction sectors. The CaReWood consortium believes that the world’s forests will not be able to adequately provide enough primary wood for the growing global resource demands without a significant improvement in resource efficiency of the whole value chain. The CaReWood project will significantly improve resource efficiency by demonstrating the potential of creating at least one additional life cycle for solid wood products. The overall objective of this project is to introduce an up-grading concept for recovered solid timber as a source of clean and reliable secondary wooden products for the European industry. Such a concept will further strengthen the market competitiveness and the sustainability of wood based products. CaReWood will develop a business model for cascade use of wood recovered from building renovation and demolition, the furniture sector and the packaging and transport industries. The scientific and technological objectives include: - present authoritative forecasts of volumes and qualities of post-consumer and post-industrial RW; - design guidelines to facilitate future reuse; - develop software supported reverse logistic models for recovery of wood; - develop, demonstrate and evaluate the feasibility of up-grading solid RW technologies; - adopt certification and labelling criteria to cascaded wood; - evaluate the environmental impacts and socio-economic viability of wood cascading. Successful up-scaling and application of the CaReWood principles by the target industries will result in: - New and viable business opportunities; - Mitigation of climate change by longer storage of captured carbon in wooden materials; - Safeguarding of resources in the biosphere; - Higher societal acceptance of renewable raw materials and recycled products by public authorities and customers; - Higher valorisation of LCA of wood products results, namely of the carbon footprint of recycled wood in the technosphere. The idea behind CaReWood is to demonstrate realistic opportunities for a first step of wood recycling allowing are-use of the material at the same level of quality, by preserving the largest possible dimensions in order to open new possibilities for subsequent uses. It is the ambition of the CaReWood consortium to contribute knowledge and data to implement high-quality wood cascading as third pillar of a sustainable recycling concept.
