Solid wastes from domestic, industrial and agricultural sectors cause acute economic and environmental problems. These issues can be partly solved by anaerobic digestion of wastes, yet this process is incomplete and generates abundant byproducts as digestate. Therefore, cultivating mixotrophic algae on anaerobic digestate appears as a promising solution for nutrient recovery, pollutant removal and biofuel production. Here we review mixotrophic algal cultivation on anaerobic waste digestate with focus on digestate types and characterization, issues of recycling digestate in agriculture, removal of contaminants, and production of biofuels such as biogas, bioethanol, biodiesel and dihydrogen. We also discuss applications in cosmetics and economical aspects. Mixotrophic algal cultivation completely removes ammonium, phosphorus, 17β-estradiol from diluted digestate, and removes 62% of zinc, 84% of manganese, 74% of cadmium and 99% of copper.

来自家庭、工业和农业部门的固体废物会导致严重的经济和环境问题。这些问题可以通过废物的厌氧消化部分解决，但这个过程是不完整的，并且会产生大量的副产物作为消化物。因此，在厌氧消化物上培养混合营养藻类似乎是一种很有前途的解决方案，可用于养分回收、污染物去除和生物燃料生产。在这里，我们回顾了厌氧废物沼渣的混合营养藻类培养，重点关注沼渣类型和表征、农业中回收沼渣的问题、污染物的去除以及生物燃料（如沼气、生物乙醇、生物柴油和氢气）的生产。我们还讨论了在化妆品和经济方面的应用。混养藻类培养完全去除铵、磷、
