One of the largest winery and cattle industry's environmental impacts is the one derived from the waste waters management. In this study, the problematic setting of residual waste waters produced in winery industry and swine industry is exposed, as well as the process, the microorganisms, the advantages and the limitations of co-digestion. A future application project of anaerobic co-digestion is proposed with an example focused on a catalane vineyard and a swine farm, with the purpose of reducing wastes, the main environmental impacts and the economic costs through both methane and electricity productio
