1-36. (canceled)
A method of manufacturing a collection of matter bound by a polymeric binder comprising:
- providing a collection of matter,
- (ii) providing a water-soluble pre-reacted binder composition in the form of an aqueous solution or dispersion, the aqueous solution or dispersion containing no more than 80 wt.-% of said pre-reacted binder composition, and the pre-reacted binder composition comprising the reaction product(s) of
- (a) at least one carbohydrate component comprising a reducing sugar and/or a component which yields a reducing sugar in situ, and
- (b) at least one nitrogen-containing component wherein the at least one nitrogen-containing component comprises polylysine,
- wherein the pre-reacted binder composition comprises at least one pre-polymer having a molecular weight in the range of 1 to 500 kDa in an amount of 2 wt.-% or more, based on the total weight of the pre-reacted binder composition,
- (iii) applying the aqueous solution or dispersion to the collection of matter, and
- (iv) applying energy to the collection of matter containing said aqueous solution or dispersion to cure the binder composition.
