The present invention relates to a method of draining water comprising the steps of: providing a water drainage device, wherein the water drainage device comprises man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition free of phenol and formaldehyde; positioning the water drainage device in contact with the ground, wherein the water drainage device absorbs water and releases water to a recipient wherein the aqueous binder composition prior to curing comprises; a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins, a component (ii) in form of one or more cross-linkers.
A method of draining water comprising the steps of:
A water drainage device comprising man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition free of phenol and formaldehyde, wherein the aqueous binder composition prior to curing comprises;
An array of two or more water drainage devices, wherein the water drainage devices comprise man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition free of phenol and formaldehyde, wherein the aqueous binder composition prior to curing comprises:
A method of producing a water drainage device comprising the steps of:
Use of a lignin component in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins, for the preparation of a binder composition free of phenol and formaldehyde for a water drainage device comprising man-made vitreous fibres (MMVF).
