This work focuses on the development of new bio-based polyurethane hot melt adhesives based on renewable raw materials (plant-based origin) from sustainable natural certified resources. After a first introduction concerning the definition of bio-based products, we will analyse the different approaches for the bio-based content evaluation (e.g. mass balance vs C14 analysis). We will describe the development of new bio-based polyurethane hot melt for profiles wrapping and edge banding comparing their chemical physical and applicative characteristics with standard fossil-based products. With reference to specific products, we will analyse the achievable reduction of carbon footprint we obtained substituting fossil-based raw material with bio-based ones. At the end, we will describe the added value of using bio-based PUR hot melt within the furniture industry and the current availability of sustainable products within this sector.
