Sewage sludge, which is fully of organics and nutrients, is often used for fertiliser. But sewage sludge can contain pathogens, microplastics, heavy metals, PFAS and chemicals. Pyrolysis (high heat/no oxygen) is a process often used to render biomass (sludge) safe. RMIT have developed a novel pyrolysis reactor which optimises heat/mass transfer processes. This translates directly into savings in capital and operating costs. It also delivers a 30% reduction in CO2 emissions, while shrinking the tech to make it highly mobile. Trials of the new reactor in real-world applications are underway in Victoria, Australia.
