Green technology LCA for wood manufacturing: plywood glued from green veneers technology

Abstract

Vacuum moulding technologies enable to manufacture plywood. It enables to glue a green state wood, because it can be dried and glued by the vacuum in the same operation. It reduces considerably the number of steps in its manufacturing. The aim of this paper is to propose a Life Cycle Assessment (LCA) in order to validate the use of vacuum process with green plywood in the hulls of boats. The functional analysis focussed on 4 traditional plywood in order to compare them with our product. The environmental modelling is carried out according to norm ISO 14040, starting from existing eco-invent (c) data base enriched with measurements taken during the manufacturing process. The results show the significant interest in the technology of gluing green wood with vacuum process. For an industrial use, this new technology is disadvantaged by the use of consumables which could be reduced considerably in industrial production by using reusable consumables
