[en] The integration of easily available and under-exploited biomasses is considered a sustainable strategy in
biorefining approaches. Mediterranean countries, especially Algeria, Morocco, and Tunisia, offer such
under-exploited waste of different origins. This study revealed the chemical composition and phytochemical characteristics of various agri-food side-products, marine residues, and wild grasses collected
in the Maghreb region. Results showed that these wastes contained variable proportions of polysaccharides, lignin, constitute molecules (proteins, lipids, and inorganic molecules) and, various secondary
metabolites, mainly flavonoids and condensed tannins. Based on this, the Mediterranean waste was
divided into three categories. The first category included waste with high lignin content (40 wt%). The
second category contained waste with lignin content below 10 wt% and structural carbohydrate content
below 50 wt%. Additionally, the waste in this category comprised noticeable amounts of flavonoids and
condensed tannins, particularly from thistle, speedwell, and spurge. Finally, the third category included
waste with lignin content above 15 wt% and carbohydrate content in the range of 45–55 wt%. The results
also showed that the waste in the third category has a chemical composition similar to that of raw materials envisioned for use in European or North American commercial biorefineries. The findings of this
study indicate that the biomass waste employed in this study can be used to develop marketable bioproducts and may be a potential raw material for a biorefinery facility.
