NOVELTY - Production of bio-energy product (400) comprises providing an industrial waste stream (420) including nutrient compounds capable of providing a nutrient rich environment when mixed with water; mixing the industrial waste stream with a water source to produce a nutrient rich water (430); propagating a population of microorganisms (440) including algae, archaea, bacteria, methanogenic microorganisms, pH tolerant microbes, heat tolerant microbes, and/or brine tolerant microbes in the nutrient rich water; and recovering bio-energy product (450) produced by the population of microorganisms.    USE - The method is for production of bio-energy product i.e. biotic methane and biomass used to produce hydrocarbon fuel or biofuel and to recover heavy metals (claimed). Biomass is used to produce e.g. lubricants.    ADVANTAGE - Currently, industrial plants expend a significant amount of resources to separate and extract compounds from the waste streams. In contrast, the method avoids many of the costs incurred to dispose of industrial waste streams by using the waste stream as a nutrient rich stream for growing algae and bacteria. Using materials in the waste stream to support microbial growth efficiently recovers the resources in the waste stream and can efficiently sequester CO2, SOx, NOx, heavy metals, and other pollutants that may be harmful if discharged.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) production of biotic methane comprising providing an industrial waste stream (420) including nutrient compounds capable of providing a nutrient rich environment when mixed with water; providing a geological formation that includes a hydrocarbon material; providing a water source (410) within the geological formation; mixing the industrial waste stream with the water source to produce a nutrient rich water (430); providing a microbial population and/or microbial component(s) within the geological formation; allowing the microbial population to propagate (440) and produce biotic methane using the hydrocarbon material and the nutrient rich water; and recovering a portion(s) of the biotic methane from the geological formation; and    (2) a system for bio-energy recovery and/or production comprising water source; an industrial waste stream including nutrient compounds capable of producing a nutrient rich water when mixed with water; and a population of microorganisms to propagate in the nutrient rich water, where population of microbes includes algae, archaea, bacteria, methanogenic microorganisms, pH tolerant microbes, heat tolerant microbes, and/or brine tolerant microbes.
