EXTRACELLULAR POLYMERS FROM GRANULAR SLUDGE AS SIZING AGENTS

摘要

An invention in the field of papermaking that relates in particular to sizing paper. Problems with state of the art methods are that the sizing chemicals used are typically expensive; may be available only in limited supply; are produced using methods that are damaging to the environment; and whose production is far from carbon-neutral. It is an object of the present invention to provide an alternative to the methods of the prior art and to overcome one or more of the above mentioned disadvantages.
