The industrial processing of meat and dairy production consumes a significant amount of fresh water, leading to the generation of large volumes of wastewater. As freshwater resources become scarce, there is increasing interest in reusing wastewater from slaughterhouses and dairy production, as well as recovering by-products. Electrochemical treatments are gaining attention for their application in treating these industrial wastewaters, with potential for value-added products and energy recovery.
The industrial processing of meat and dairy production uses large amounts of fresh water, therefore, generates a significant volume of wastewaters. The treatment of these effluents has been performed using different technologies from biological to electrochemical advanced oxidation processes. Under the circular economy concept, the lack of available freshwater resources has increased the interest in reusing wastewater from slaughterhouses, and even in the recovering of by-products. This article reviews the application of electrochemical treatments to slaughterhouse and dairy wastewaters. In addition, an overview of added-value products and energy recovery from these industrial wastewaters is also presented with future perspectives.
