Sign upHandling wastewater sludge for heating and biocharging
There is a growing concern about what to do with sewage sludge due to concerns of environmentally unfriendly pharmaceuticals, microplastic and chemical compounds (PAHs, furans, dioxins, NPE, LAS etc). In many countries, sludge is now incinerated instead of spread on land due to public health concerns. This creates a problem of locking Phosphorus in the ash making it very difficult and expensive to recycle it into the soil. Sludge can only be spread on land 3 months a year and the prolonged storage gives considerable GHG emission. AquaGreen dries and pyrolyses (heat to 650 °C) the sludge turning it into useful resources - energy and biochar w. phosphorus - solving environmental and climate problems of sewage sludge. It the farmer to better yields and the climate by storing CO2 in the ground when biochar is used as a fertilizer. It also supports future generations ability to grow plants by recovering phosphorus - an element which is listed as a critical scarce raw material by EU.
