Yorkshire Water is at the forefront of a £2.3 million project, funded by the Ofwat Innovation Fund, to transform sewage sludge into valuable products like biochar, vitrified ash 'stones,' and hydrogen-rich synthesis gas. This initiative, utilizing Advanced Thermal Conversion Gasification technology, aims to eliminate contaminants and repurpose waste for beneficial applications. The project involves a consortium consisting of technology provider EnertecGreen, Queen’s University Belfast, Carbon Trust, and several major water companies. Notable participants include Thames Water, United Utilities, Anglian Water, Scottish Water, and others. The project envisions a circular economy approach by repurposing biochar for wastewater treatment and construction materials, potentially reducing the carbon footprint in these sectors. The carbon-rich biochar offers improved soil water retention and nutrient retention, making it a sustainable option for long-term carbon sequestration. Moreover, the vitrified ash 'stones' are expected to serve as sustainable aggregate in construction, contributing to lower carbon emissions. The synthesis gas generated, containing hydrogen among other components, can be utilized for green electricity production and the creation of high-value products like aviation fuel. Dr. Danielle Hankin, Yorkshire Water's Innovation Programme Manager, highlighted the project's significance in offering more sustainable uses for sewage sludge and driving the industry towards a greener future. Ofwat's Senior Director, Helen Campbell, praised the project for its innovative solutions that address challenges in the water industry, emphasizing the importance of transformational changes for customers, society, and the environment. This project represents a pivotal step towards a more resource-efficient and sustainable water sector.
