The present invention relates to biobased binder compositions which are environmentally benign, renewable, compostable and/or biodegradable. The biobased compositions comprise chitosan, an acid and a plasticizer. By treating an airlaid nonwoven material with a biobased binder according to the present invention, it is possible to provide an airlaid nonwoven material exhibiting higher elongation, i.e., elongation at break, and strength compared to an airlaid nonwoven material treated with previously available biobased binders.
