Abstract: A composition is contained a blend zone prior to refining containing non-fibrillated virgin cellulose fibers, waste/recycle cellulose fibers or both; cellulose ester fibers, water, and one or more additives comprising fillers, internal sizing agents, biocides, process anti-foaming agents, colorants, optical modifiers, or a combination thereof. An in-line mixer can be used for adding the additives, and the consistency of the composition is lowered relative to a feed of material from a hydropulper.

IPC: C07C67/44
Abstract: A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content glycol ester by deducting from a recycle inventory a recycle content value applied to a glycol ester composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a glycol ester manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

Abstract: A hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to the cracker feed. More specifically the-pyoil is present in said feedstock in an amount of not more than 20% by weight, based on the total weight of the feedstock.
