Innovative recycling and treating of waste
Sludge from Scotland's North East is treated using the CAMBI anaerobic digestion process; producing a high tier sought-after agricultural product and minimising the impact on the environment. During the process, sludge is hydrolysed and pasteurised using pressure and steam resulting in a high pathogen kill. This is a sustainable process avoiding the use of UV or harmful chemicals. View a short video about the CAMBI process.
Methane is also produced as a by-product and is used to power two Combined Heat and Power (CHP) engines. As well as generating electricity; the heat produced by the CHP's is captured and reused, making for a thermodynamically efficient use of fuel and aiding in efforts towards environmental sustainability and energy recycling.
