Processing conditions analysis of Eucalyptus globulus plywood bonded with resol-tannin adhesives

Green extraction process of tannins obtained from Moroccan Acacia mollissima barks by microwave: Modeling and optimization of the process using the response surface methodology RSM

“…The high level of extractables in the barks of Acacia rich in natural tannins constitutes a potential substitute to synthetic phenols. Recently, the tannins of the A. mollissima were used in lot of applications: wood protection (Tascioglu et al, 2013;Hayoz et al, 2003), inhibition of corrosion (Gerengi and Halil, 2012;Silveira et al, 2012), elaboration of carbon foam (Basso et al, 2013;Tondi et al, 2010;Zhao et al, 2010), elaboration of natural adhesive with low emission of formaldehyde (Bertaud et al, 2012;Sumin, 2009;Stefani et al, 2008), elaboration of thermoplastic (Nicollin et al, 2013), fertilization of sea urchins and development of the growth algal of sea (De Nicola et al, 2007). After tannin extraction, the residual bark of A. mollissima may also be used in the composting to produce the organic fertilizer, or as biomass fuel (Foelkel, 2008).…”

Comparison of the impact of different extraction methods on polyphenols yields and tannins extracted from Moroccan Acacia mollissima barks

“…This category includes a whole range of compounds whose majority are secondary metabolites, like polyphenols, mostly condensed tannins and hydrolysable tannins (Stevanovic and Perrin, 2009 in the barks of Acacia rich in natural tannins constitutes a potential substitute to synthetic phenols. Recently, the tannins of the A. mollissima were used in a lot of applications: wood protection (Tascioglu et al, 2013;Hayoz et al, 2003), corrosion inhibition (Gerengi and Halil, 2012;Peres et al, 2012), elaboration of carbon foam (Basso et al, 2013;Tondi et al, 2010Zhao et al, 2010, elaboration of natural adhesive with low formaldehyde emission ( Bertaud et al, 2012;Sumin, 2009;Stefani et al, 2008), elaboration of thermoplastic (Nicollin et al, 2013), fertilization of sea urchins and development of sea growth algal (De Nicola et al, 2007), and also elaboration of carbon gels (Szczurek et al, 2011). After tannin extraction, the residual bark of A. mollissima may be used in the composting to produce organic fertilizer, or as biomass fuel (Foelkel, 2008).…”

Physico-mechanical properties of plywood bonded with ecological adhesives from Acacia mollissima tannins and lignosulfonates

“…Natural tannin is an excellent renewable resource, which can be used for replacing petroleumderived phenolic compounds. The major species from which it can be obtained are mimosa (also known by Acacia mollissima, Acacia mearnsii and Black wattle), quebracho and radiata pine [11,12]. The chemical structure of Acacia mollissima tannin is shown in Figure 1.…”
