Abstract
A method of growing plants in a coherent growth substrate product is provided and includes: providing at least one coherent growth substrate product comprising man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition; positioning one or more seeds, seedlings, cuttings or plants in contact with the growth substrate product; and irrigating the growth substrate product. The aqueous binder composition prior to curing includes a component (i) in the form of one or more oxidized lignins, a component (ii) in the form of one or more cross-linkers, and a component (iii) in the form of one or more plasticizers.
Claims21
A method of growing plants in a coherent growth substrate product, the method comprising:
- providing at least one coherent growth substrate product comprising man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition;
- positioning one or more seeds, seedlings, cuttings or plants in contact with the growth substrate product;
- and
- irrigating the growth substrate product;
- wherein the aqueous binder composition prior to curing comprises:
- a first component (i) in the form of one or more oxidized lignins;
- a second component (ii) in the form of one or more cross-linkers;
- and
- a third component (iii) in the form of one or more plasticizers.
A coherent growth substrate product comprising man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition, wherein the aqueous binder composition prior to curing comprises:
- a first component (i) in the form of one or more oxidized lignins;
- a second component (ii) in the form of one or more cross-linkers;
- and
- a third component (iii) in the form of one or more plasticizers.
An array of two or more coherent growth substrate products, wherein each coherent growth substrate product comprises man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition, wherein the aqueous binder composition prior to curing comprises:
- a first component (i) in the form of one or more oxidized lignins;
- a second component (ii) in the form of one or more cross-linkers;
- and
- a third component (iii) in the form of one or more plasticizers.
A method of making a growth substrate product comprising the steps of:
- providing MMVF;
- (ii) spraying the MMVF with an aqueous binder composition;
- (iii) collecting and consolidating the MMVF;
- and
- (iv) curing the aqueous binder composition;
- wherein the aqueous binder composition prior to curing comprises:
- a first component (i) in the form of one or more oxidized lignins;
- a second component (ii) in the form of one or more cross-linkers;
- and
- a third component (iii) in the form of one or more plasticizers.
