    Abstract: This disclosure provides a business method and system for generating sugars and recycling a non-biomass component from a waste stream. In some embodiments, a waste stream comprising cellulose and a non-biomass component is saccharified to produce glucose, followed by recovery of the glucose and non-biomass component, which may be recycled to another site associated with production of a cellulose-containing product that contains the non-biomass component. In certain scenarios, the waste stream is generated at a first location, cellulose pretreatment (if desired) and hydrolysis are conducted at a second location, and the non-biomass component is recycled to the first location or a third location. The non-biomass component may include metals, metal oxides, salts, organic compounds, inorganic compounds, oligomers, or polymers, for example.
