**Industrial activities generate large volumes of solid and liquid organic wastes** **Anaerobic digestion provides a solution to treat these streams, recovering nutrient-rich fertilizer, reducing landfill reliance and water stress and producing green energy.** Veolia develops and operates anaerobic digestion systems that [convert organic matter into biogas](https://www.youtube.com/watch?v=lHyL41grGUo&list=PL9opkHFYSV4I2ZXENU9CqdJBSmSwfLzCG&index=15), which can be reused on-site as an energy source.
