The present invention relates to a binder composition comprising a) Component A comprising amino acid polymer(s) A1 and b) Component B comprising component B1 selected from the group consisting of pentoses, hexoses, disaccharides of pentoses and/or hexoses and mixtures thereof, wherein the amino acid polymer(s) A1 has(have) a total weight average molecular weight Mw,total of at least 800 g/mol and at most 10.000 g/mol and wherein the binder composition comprises at least 55 wt.-% amino acid polymer(s) A1 based on the total weight of the amino acid poly- mer(s) A1 and component B1. La présente invention concerne une composition de liant comprenant a) un composant A comprenant un ou plusieurs polymères d'acide aminé A1 et b) un composant B comprenant le composant B1 choisi dans le groupe constitué de pentoses, hexoses, disaccharides de pentoses et/ou hexoses et des mélanges de ceux-ci, le ou les polymères d'acide aminé A1 ayant une masse moléculaire moyenne en poids Mw, total d'au moins 800 g/mol et au plus 10 000 g/mol et la composition de liant comprenant au moins 55 % en poids du ou des polymères d'acide aminé A1 sur la base du poids total du ou des polymères d'acide aminé A1 et du composant B1.
