“…The potential of argan processing waste, especially of Argan Nut Shells (ANS), to produce environment-friendly and low-cost purifying and absorbent materials is particularly interesting for its economic valorization and for environmental remediation. Early studies focusing on the use of ANS or of argan bark and argan endocarp for biosorption of methylene blue, or of Cd(II) and Pb(II) dates back to 2012 (Legrouri et al 2012;Hachem et al 2012). Thereafter, the number of papers dealing with this issue has rapidly increased, also due to the fact that water pollution with different chemicals and/or pharmaceutical products is raising major concern for public health.…”

Argan tree is endemic of Moroccan arid regions, providing socioeconomic and cultural benefits since ancient times. This study identifies the emerging threats for the argan forest, and the opportunities related to the innovative uses of argan products and byproducts. Argan forest is facing pressure from overgrazing, demand for argan oil and nuts, and land degradation, despite its recognition as a UNESCO Biosphere Reserve and the inclusion in the FAO Globally Important Agricultural Heritage Systems (GIAHS) Programme. Innovative use and recycling of the waste deriving from argan nuts processing, offer promising opportunities to support a local bio-economy. Argan press cake can be used to integrate livestock feeding, to extract sudan dyes or to produce bioplastics. Argan nut shells can be used to produce environment-friendly and low-cost purifying materials and biochar, or as a source of bioenergy. Argan pulp can be used for bioethanol production or to obtain natural insect repellent. Despite these promising opportunities, the socio-economic impact of innovative uses is still limited. Local population is not sufficiently involved in management and development strategies. To support the sustainable development of local communities, it is necessary to promote a participative approach as well as training and product differentiation among argan women cooperatives.

“…Five biomass modifications have been carried out by washing the sawdust (5 g, 0.2 mm) with different reagents following chemical protocols optimized from the literature ( Hachem et al., 2012 ; Astier, 2010 ; Varmat and Chavan, 1995 ).…”

“…The oxidation technics to get dialdehyde (SCHO), di-carboxylic (SCOOH(2)) and tricarboxylic (SCOOH(3)) sawdust have been optimized from polysaccharide oxidation described in the literature (Hachem et al, 2012;Varmat et al, 1995). Therefore, dicarboxylic sawdust (SCOOH(2)) was obtained by reaction of 1.5 g of dialdehyde sawdust J o u r n a l P r e -p r o o f (SCHO) in 600 mL of sodium chlorite (0.3 M).…”

“…Beside essential metal ions, natural melanins from squid and fungi and melanin-based synthetic pigments are regarded as efficient chelators of heavy metals. Up to now, most of these materials, including also rough agricultural wastes, have been investigated only for applications in water and soil remediation − but, in no case, have been evaluated as food supplements to prevent bioaccumulation of dietary heavy metals.…”

Black sesame pigment (BSP) was shown to bind lead, cadmium, and mercury at pH 7.0 and to a lower extent at pH 2.0. BSP at 0.05 mg/mL removed the metals at 15 μM to a significant extent (>65% for cadmium and >90% for mercury and lead), with no changes following simulated digestion. The maximum binding capacities at pH 7.0 were 626.0 mg/g (lead), 42.2 mg/g (cadmium), and 69.3 mg/g (mercury). In the presence of essential metals, such as iron, calcium, and zinc, BSP retained high selectivity toward heavy metals. Model pigments from caffeic acid, ferulic acid, and coniferyl alcohol showed lower or comparable binding ability, suggesting that the marked properties of BSP may result from cooperativity of different sites likely carboxy groups and o-diphenol and guaiacyl functionalities. Direct evidence for the presence of such units was obtained by structural analysis of BSP by solid-state Fourier transform infrared spectroscopy and (13)C nuclear magnetic resonance spectroscopy.
