Changes in both formaldehyde legislations and voluntary requirements (e.g. Germany RAL) are currently the driving factors behind research on alternatives to amino-based adhesives; moreover, consumer interest in healthy and sustainable products is increasing in bio-based adhesives. Sources of formaldehyde emissions in wood-based panels as well as different emission test methods have been discussed, and the main focus of this review is on the research conducted on sustainable bio-based adhesive systems for wood panels. Lignin, tannin, protein, and starch have been evaluated as both raw materials and adhesive alternatives to existing amino-based thermosetting adhesives. Adhesion improving modifications of these bio-based raw materials as well as the available and experimental crosslinkers have also been taken into account.

- Review of state of the art of dowel laminated timber members and densified wood materials as sustainable engineered wood products for construction and building applications (2020, unknown): “Although there are ongoing developments of environmentally friendly bio-based adhesives, there are still challenges to their wider uptake due to the lower cost and better properties of synthetic petroleum-based adhesives (Hemmil € a et al., 2017; Norstr € om et al., 2015).”
- Adhesive systems used in the European particleboard, MDF and OSB industries* (2018, background): “Lately, there has been a high research interest in bio-adhesives mainly in soy-based adhesives (Vnučec et al. 2017), as well as in lignin- and tannin-based adhesives (Nakos et al. 2016, Hemmilä et al. 2017, Papadopoulou 2017).”
