Method for the use of heat, especially ''waste heat'', from geothermal steam or brines for the manufacture of chemicals such as alcohol, which comprises, according to one embodiment, flashing the brine to produce steam, passing the steam to a turbine for electrical energy generation, and employing the steam from the turbine discharge and/or the flashed brine to provide some or all of the heat requirements for the fermentation distillation process for production of alcohols, e.g. (methanol and/or ethanol) from agricultural wastes. The method can also be utilized for the production by distillation and/or by industrial fermentation and/or by hydrolysis of other chemicals (such as furfural and acetone).
