“…In the same way, tannins are natural polyphenols widely present in nature but only condensed tannins have a sufficient chemical reactivity to be potentially developed (Pizzi, Scharfetter, & Kes, 1981). Tannins can successfully be used as binder for non-woven natural fibers (Pizzi, Kueny, & Lecoanet, 2011), wood particleboards (Pizzi, 1982;Pizzi et al, 1981) and natural fibers such as flax or hemp (Nicollin, Kueny, Toniazzo, & Pizzi, 2012;Pizzi et al, 2009). However, tannins extraction is expensive and water costly, limiting its industrial development.…”

Alginate derived from seaweed is a natural polysaccharide able to form stable gel through carbohydrate functional groups largely used in the food and pharmaceutical industry. This article deals with the use of sodium alginate as an adhesive binder for wood fibres/textile waste fibres biocomposites. Several aldehyde-based crosslinking agents (glyoxal, glutaraldehyde) were compared for various wood/textile waste ratios (100/0, 50/50, 60/40, 70/30 and 0/100 in weight). The fully biomass derived composites whose properties are herewith described satisfy most of the appropriate requirements for building materials. They are insulating with a thermal conductivity in the range 0.078-0.089 W/m/K for an average density in the range 308-333 kg/m3 according to the biocomposite considered. They are semi-rigid with a maximal mechanical strength of 0.84 MPa under bending and 0.44 MPa under compression for 60/40 w/w wood/textile waste biocomposites with a glutaraldehyde crosslinking agent.

In recent years industries are attempting to decrease their dependency on petroleum-based fuels and products due to increased environmental issues. The tremendous increase in production and use of plastics in every sector of life has led to huge plastic waste disposal problems and also an environmental threat. In order to prevail over the present scenario, the viable and cost-effective approaches are to prepare eco-friendly bio-composites based on non-wood forest products (NWFP), a part of forest wealth of the globe, especially natural fibres, agricultural wastes and extractives. Natural fibres and extractives have many advantages viz. low density, low cost, considerable toughness properties, nontoxicity, sustainability and biodegradability. NWFP based composites may be utilized to produce non-structural parts for diverse applications in various industries as high-performance materials with interesting properties for specific applications viz. furniture, thermal, acoustic insulations and automotive industries etc. In the present chapter, opportunities of extractives, cellulosic and lignocellulosic fibres from non-wood forest products in Bio-composites will be discussed.

“…Nonwoven flax and hemp fiber mats were impregnated with renewable bio-sourced resin matrices to yield both high and low density composites of good performance [133,134,135,136] (Figure 17). The types of bio-sourced matrices used were: (1) a 5% hexamethylenetetramine-hardened resin based on commercial mimosa tannin extract, and (2) a 50/50 combination by weight of glyoxalated organosolv lignin of low molecular weight and of mimosa tannin with hexamethylenetetramine.…”

The origin of tannins, their historical evolution, their different types, and their applications are described. Old and established applications are described, as well as the future applications which are being developed at present and that promise to have an industrial impact in the future. The chemistry of some of these applications is discussed where it is essential to understand the tannins and their derivates role. The essential points of each application, their drawbacks, and their chance of industrial application are briefly discussed. The article presents historical applications of tannins, such as leather, or traditional medicine, and more recent applications.
