“…Most recently, the Pizzi group showed that tannin-FA chemistries can be implemented for wood adhesives avoiding the use of formaldehyde, for foams without using blowing agents or formaldehyde, and for thermosetting plastics [176,180,181]. The first two methods are important because they reduce fossil-based formaldehyde and represent a greener approach to the production of solvent-free foams [176].…”

“…The first two methods are important because they reduce fossil-based formaldehyde and represent a greener approach to the production of solvent-free foams [176]. The thermosetting plastics produced by condensation reactions between tannin and FA could be molded and exhibited good post-curing mechanical and thermal properties [181]. Figure 5.6 shows the cross-linked networked formed by these materials; the incorporated aromatic and cyclic species indicate good material strength.…”

“…Afterwards, major advances were achieved first with tannin-furanic foams without formaldehyde (Basso et al 2011) or modification with small amounts of polyisocyanate (Li et al 2012a), second with foams using a safer blowing agent, namely pentane, and even with no blowing agent at all (Basso et al 2013a;Li et al 2013b), third with foams using alternative non-toxic, nonvolatile aldehydes , and finally using the much more reactive and difficult to handle procyanidin-type tannins such as for example pine and spruce bark tannins (Cop et al 2014;Lacoste et al 2013Lacoste et al , 2014. Even simplified foams in which the tannin was substituted with fine wood powder were tried (Srivastava and Pizzi 2014).…”

& Key message Green chemistry for and from wood has developed numerous industrial products, namely biosourced, green wood adhesives and preservatives, foams, composite matrices, laminates, hard and flexible plastics, flexible films, and abrasive grinding discs, and their number is still growing. & Introduction This review addresses (1) the elimination of toxic aldehydes from the most common wood panel adhesive, the one based on urea, itself a natural product, (2) biosourced adhesives derived from wood or other vegetable matter and used for wood products, and (3) wood and bark tannin-based foams, natural fiber composites using tannin matrices, paper surface laminates and continuous high-pressure paper laminates using tannin-furanics, hard plastics based on tanninfuranic materials and some of their applications, flexible biosourced tannin-furanic films, and biosourced wood preservatives.

“…Among the materials commonly used, néré tannins holds an important place. It is also noteworthy that tannins have become a subject of renewed attention in recent decades for use in several areas, such as environment friendly biosourced polymeric materials (Nouailhas et al, 2011;Celzard et al, 2012;Kuzhir et al, 2012;Abdullah et al, 2013;Amaral-Labat et al, 2013;Li et al, 2013;Thebault et al, 2014;Basso et al, 2014). Of all of the uses of tannins, our study is inspired by the traditional practice where locust bean pod tannins are used to improve the durability of traditional housing.…”

Buildings made of unbaked clay have some advantage in terms of production cost. However, they have some inconveniences concerning their mechanical performance, particularly their resistance to weather. The objective of this study is to minimize these disadvantages and to maximize the benefits of such buildings to make them more viable. For this purpose, a method based on a traditional practice where the néré pod is utilized as a color wash, as well as, a binder is used. In the first case (color wash), it is to protect the building against weather damage, in the latter case, it is used to improve the mechanical performance of the coatings on the ground and it is in this way that rural people use to keep more sustainable homes. To achieve this, geotechnical characteristics were studied on seven (07) soil samples collected in seven (07) localities in Togo (Kovié, Aouda Zanguéra, Sarakawa Tagbamba, Goumoukopé and BB Lomé). The same geotechnical characteristics were studied on the same soil samples enhanced by adding the néré pods. Finally, a study was conducted to optimize the performance of this new composite material (soil-néré pod) based on the proportion of néré pod within the material. To manufacture a brick of dimensions of 22×14×9.5 cm, 8.5 kg of the mixture was needed and the amount of dampening water needed was equal to the amount of water to obtain optimum Proctor plus 2%. The results of these tests confirmed that néré pods help to improve the mechanical performance, especially the resistance to compression and puncture of the soils under consideration.
