Abstract
A process provides for the production of fertilizer solutions from brewery cleaning solutions. The process comprises the steps of combining a brewery caustic potash cleaning solution with a brewery nitrogen- or phosphorus-containing acid cleaning solution in mutually neutralizing amounts. This process results in the production of a fertilizer solution comprising a neutralized potassium salt solution having nitrogen-containing, organic, brewing materials entrained therein. If desired, spent grains and/or spent yeast from the brewing process can be added to provide further nutrients.
