Driven by a commitment to building sustainable and economically efficient solutions, our team at Clarence Correctional Centre (CLA) has achieved a significant environmental milestone through the successful application of biosolids to land within the facility. This innovative approach has reduced methane emissions by up to 90%—equivalent to taking 200 cars off the road for a year—and saved the centre approximately $50,000 in transport and landfill costs. The biosolids, a by-product from the Waste Water Treatment Plant (WWTP) at the centre, were historically disposed of in landfills, contributing significantly to harmful methane emissions. With an annual disposal requirement of roughly 140 tonnes based on the current occupancy, the centre faced a considerable challenge to manage this waste sustainably. Despite harsh weather conditions and tight time constraints, our team successfully navigated these obstacles. Rainfall totals in May were 25.2% above the area average, delaying the application process and threatening the functionality of the WWTP. The application area, characterised by fine clay subsoil, required extended drying periods before heavy machinery could access the site. Despite these challenges, the project has delivered substantial environmental and economic benefits. The practice has recovered around 6,900kg of phosphorus and 9,300kg of nitrogen, replacing an equivalent of 56.4 tonnes of CO2 associated with agricultural fertiliser production. To put this into perspective, the amount of nitrogen recovered is equivalent to the nitrogen content in about 930,000 litres of cow milk! This not only addresses waste management challenges but also contributes to significant environmental and economic benefits, paving the way for more sustainable practices in the future. Josh Hollington, the Plumbing Supervisor at CLA, is a driving force behind the centre's sustainability initiatives. With a diverse career background in plumbing, mining, and bridge construction, Josh joined Serco in February 2020 and quickly established himself as a key figure in the centre's environmental efforts. "Since joining, my role has evolved significantly. I now lead the hydraulic services team, oversee maintenance, repair activities, and lifecycle replacement in line with contractual obligations,” Josh explained. As his role has expanded, so has his autonomy to innovate, aiming to improve processes, pre-empt issues, and showcase impactful change in environmental management. This successful initiative at CLA serves as a model for other facilities around the world, demonstrating that with innovative thinking and determination, significant environmental improvements are achievable. #ESG #EnvironmentalInitiatives #Sustainability #GreenFuture #SercoASPAC #ImpactABetterFuture
