Due to growing worldwide population, dairy sector expanding producing waste such wastewater (from cleaning, processing, maintenance), whey, sludge. These elements are nutrient-rich contain both organic inorganic compounds. Dairy also danger environment due alkaline acidic detergents sterilising agents that included in it. Thus, utilisation biological techniques, as microbial treatment, necessary for sustainable valorization waste. This paper highlights recent advancements use valuation microorganisms. Using microbes handle aerobically anaerobically environmentally friendly way produce biofertilizers, biofuels, electricity, other biobased products.
