Methods, processes, apparatus, systems, and compositions are disclosed for improving the sustainability of oil sands processing. In some embodiments, bitumen is combined with biodiluent comprising one or more liquid pyrolysis fractions obtained from pyrolyzing biomass and collecting multiple liquid fractions. The bitumen may be any source of bitumen, such as bitumen obtained from oil sands. In some embodiments, a water-rich pyrolysis liquid displaces water use in an oil sands process. The water-rich pyrolysis liquid may be used for primary separation of bitumen from oil sands or for hydrotransport, for example. Also, biochar produced from biomass pyrolysis may be introduced to an oil sands tailing pond with various benefits. Water may be recycled from a tailing pond. Integration of a pyrolysis and separation process into an oil sands refining process reduces the overall greenhouse-gas emissions on a well-to-refined product basis by 10-70% or more. Various compositions and products are also disclosed.

1. A method comprising combining biodiluent with bitumen to form diluted bitumen, wherein said biodiluent comprises a liquid pyrolysis oil obtained from biomass pyrolysis, and wherein said biodiluent contains less than 10 wt % water. 2. The method of claim 1, wherein said liquid pyrolysis oil compri
1. A method comprising combining biodiluent with bitumen to form diluted bitumen, wherein said biodiluent comprises a liquid pyrolysis oil obtained from biomass pyrolysis, and wherein said biodiluent contains less than 10 wt % water. 2. The method of claim 1, wherein said liquid pyrolysis oil comprises at least a portion of an organic phase of a liquid produced during said biomass pyrolysis. 3. The method of claim 1, wherein said biodiluent is substantially soluble with said bitumen at a processing temperature selected from about 40° C. to about 90° C. 4. The method of claim 1, said method further comprising a step of combining diluent with said bitumen to form said diluted bitumen. 5. The method of claim 4, wherein the addition of said biodiluent reduces the quantity of said diluent necessary to maintain a selected viscosity of said diluted bitumen. 6. A method comprising combining biodiluent and diluent with bitumen to form diluted bitumen, wherein said biodiluent comprises a liquid pyrolysis oil obtained from biomass pyrolysis, and wherein said biodiluent contains less than 10 wt % water. 7. The method of claim 6, wherein said liquid pyrolysis oil comprises at least a portion of an organic phase of a liquid produced during said biomass pyrolysis. 8. The method of claim 6, wherein said biodiluent is from 0.1 wt % to 20 wt % of the total of said diluted bitumen. 9. The method of claim 6, said method further comprising recovering said diluent from said diluted bitumen, and then recycling said diluent. 10. The method of claim 6, wherein said biodiluent is not recovered from said diluted bitumen. 11. The method of claim 6, said method further comprising introducing said diluted bitumen to a unit for refining, upgrading, or chemical conversion. 12. The method of claim 11, said method comprising converting at least a portion of said biodiluent into fuels, chemicals, materials, or energy. 13. The method of claim 12, said method comprising converting at least a portion of said biodiluent into bio-based asphalt or bio-based asphalt cement.
