A method for the manufacture of mineral wool products is disclosed. In one example, the method comprises reacting an aqueous phenol-formaldehyde resole with free formaldehyde with a first amount of urea, thereby preparing a prereact. The prereact is contacted with a second amount of urea. The resulting mixture of prereact and second amount of urea, as part of a binder, optionally with additives is applied to the surface of mineral fibers. The binder is cured on the surface of the mineral fibers. A mineral wool product with reduced emissions of formaldehyde is also disclosed.

Most processes currently being proposed and/or used for the production of lignin from kraft or soda black liquors are capable of producing two main types of lignin: high residual content (HRC) lignin and low residual content (LRC) lignin. Surprisingly, it was discovered that HRC lignin, is a suitable ingredient in alkaline adhesives, particularly wood adhesives of the phenolic type (e.g. resole resins). This biomaterial is environmentally green and remarkably low cost, which makes it an industrially viable material to be used as a novel and major ingredient in phenolic adhesives for the manufacture of exterior grade plywood, laminated veneer lumber, oriented strand board (OSB) and other wood productsthis was successfully demonstrated in a number of laboratory experiments as well as several different mill trials. The composition, preparation and application of such wood adhesives are hereby disclosed.

The present application is directed to methods for solvent-free preparation of polymers and their subsequent processing into activated carbon materials. These methods unexpectedly demonstrate ability to tune pore structure in the polymer gel and carbon produced there from, while also providing distinct advantages over the current art.
