Valorisation of non-timber by-products from maritime pine (Pinus pinaster, Ait) for particleboard production

•Valorisation of P. Pinaster, Ait by-products by steam pressure alkali extraction was studied.•Extraction yield, extracts reactivity and chemical composition were evaluated.•Maritime pine by-products were studied as raw materials for particleboard production.•Pinecones incorporation increases the final board quality.•Pine bark showed a noticeable influence on particleboard formaldehyde emission.
