A method for producing charcoal particles or pellets which use different additives as binders for the biochar pellets. The method includes producing a mixture with charcoal and additives selected from nanocrystalline cellulose, bentonite, and polyvinyl acetate. The mixture is created by mixing one or more of the additives with charcoal and water. The mixture is then processed in a pelletizer device. While processing, the surface of the mixture is sprayed with a liquid. Once turned into pellets by way of the pelletizer device, the resulting pellets are then dried by applying heat to the pellets. The liquid can be water or a solution of water and sodium borate.

The present invention provides a method (100) for removal of metals from aqueous solutions comprising the steps of treating (102) the aqueous solutions with an adsorbent, allowing (104) the aqueous solutions and the adsorbent to be in contact for a predetermined time to obtain treated aqueous solutions, collecting (106) the treated aqueous solutions, filtering (108) the treated aqueous solutions and discharging (110) the filtered aqueous solutions. The adsorbent comprising plurality of natural biomaterials. Further, the plurality of natural biomaterials are capable of adsorbing the metals from the aqueous solutions.

The invention relates to a method of making an insulation product and a novel insulation product, wherein the insulation product is made by adhering a facing to at least one major surface of a batt of man-made vitreous fibres in a matrix comprising a binder by the use of an adhesive and curing the adhesive. The adhesive is an aqueous composition which is free of phenol and formaldehyde and comprises: a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 2.0 mmol/g, such as 0.03 to 1.4 mmol/g, such as 0.075 to 2.0 mmol/g, such as 0.075 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.
