A method for making a shaped product comprising exploded bark. Preferably the shaped product comprises exploded softwood bark having at least 23% cellulose and at least 18% lignin and polyphenols content, based upon the dry weight basis of the bark. One of the methods to make the shaped product comprises exploding softwood bark to obtain exploded softwood bark having at least 23% cellulose and at least 18% lignin and polyphenols content, compressing that exploded bark into a shaped product, while removing in part water, and drying the shaped product to remove the remaining water.

Methods for making exploded bark products

A process for recycling an asphalt-containing waste product, that comprises breaking up an asphalt-containing waste product in a liquid to produce a wet waste product mixture having particles no greater in size than 10 mesh and at least some of which are asphalt-containing particles. Thereafter the wet waste product mixture is directly used to produce a new asphalt product. New asphalt products are produced entirely or partly from the wet waste product mixture.

Process for recycling as a whole asphalt containing waste products

A shaped product comprising exploded bark. Preferably the shaped product comprises exploded softwood bark having at least 23% cellulose and at least 18% lignin and polyphenols content, based upon the dry weight basis of the bark. One of the methods to make the shaped product comprises exploding softwood bark to obtain exploded softwood bark having at least 23% cellulose and at least 18% lignin and polyphenols content, compressing that exploded bark into a shaped product, while removing in part water, and drying the shaped product to remove the remaining water.
