1. A shaped article having a three-dimensional shape, comprising a binder composition that is a mixture of binder and filler material, wherein the binder composition has been cured to provide the shaped article;
the article being obtainable by a method comprising:
a) providing a binder, wherein the binder has been produced by a process of:
i) mixing (A) fungi or glucan and (B) starch with an alkaline agent to form an alkaline composition; and mixing the alkaline composition with an acidic agent to form the binder; or
ii) mixing (A) fungi or glucan and (B) starch with an acidic agent to form an acidic composition; and mixing the acidic composition with an alkaline agent to form the binder;
b) forming a binder composition by mixing the binder with filler material;
c) shaping the binder composition into a three-dimensional shape; and
d) curing the binder composition to form a shaped article having said three-dimensional shape;
wherein step c) and step d) can be carried out simultaneously or separately, and wherein during one or both of step c) and step d) pressure is applied to the binder composition.
