  • Project to transform sewage sludge into clean water and energy awarded a share of £4.5 million by Ofwat
  • Involves extracting energy from the waste produced during sewage and water treatment
  • Gases obtained can be used to power engines or heat people’s homes.



An Aston University project that could transform sewage sludge into clean water and energy has been awarded a share of £4.5 million by Ofwat.


The University project with engineering consultancy ICMEA-UK involves extracting energy from the waste produced during sewage and water treatment and transforming it into hydrogen and/or methane. The gases can then be used to power engines or heat people’s homes.


The aim is to create a sustainable and cost-efficiently run wastewater processes, plus extra energy.


The initiative was one of ten winners of Ofwat’s Water Discovery Challenge, of which the Aston University scientists and two industrial partners have been awarded £427,000.




Dr Jude Onwudili based at Aston University’s Energy and Bioproducts Research Institute (EBRI) is leading the team of scientists who will work with the partners to develop a trial rig to transform solid residues from wastewater treatment plants to hydrogen and/or methane.


The two-stage process will involve the initial transformation of organic components in the sludge into liquid intermediates, which will then be converted to the fuel gases in a second stage.


The project is called REvAR (Renewable Energy via Aqueous-phase Reforming), and Dr Onwudili will be working with lead partner and engineering consultancy company ICMEA-UK Limited and sustainable infrastructure company Costain.


REVAR combines the use of hot-pressurised water or hydrothermal conditions with catalysts to achieve high conversion efficiency. The technique can treat sewage sludge in just minutes, and it is hoped that it will replace existing processes. In 2013, a Chartered Institution of Water and Environmental Management report stated that the sector is the fourth most energy intensive industry in the UK.


Dr Onwudili said: “This project is important because millions of tonnes of sewage sludge are generated in the UK each year and the water industry is struggling with how to effectively manage them as waste.


“Instead, they can be converted into valuable feedstocks which are used for producing renewable fuel gases, thereby increasing the availability of feedstocks to meet UK decarbonisation targets through bioenergy.


“We will be taking a waste product and recovering two important products from it: clean water and renewable energy. Overall, the novel technology will contribute towards meeting UK Net Zero obligations by 2050 and ties in with the University’s purpose to make our world a better place through education, research and innovation.”


The Water Discovery Challenge aims to accelerate the development and adoption of promising new innovations for the water sector. Over the next six months, winners will also receive non-financial support and will be able to pitch their projects to potential water company partners and/or investors.


The 10 winning teams are from outside the water industry and were chosen because of their projects’ potential to help solve the biggest challenges facing the sector.  


The competition is part of the Ofwat Innovation Fund, run by the water regulator Ofwat, with Challenge Works, Arup and Isle Utilities and is the first in the water sector to invite ideas from innovators across industries.


Helen Campbell, senior director for sector performance at Ofwat, said: “This competition was about reaching new innovators from outside the sector with different approaches and new ideas, and that’s exactly what the winners are doing.


“The products and ideas recognised in this cross-sector challenge will equip water companies to better face challenges of the future – including achieving sustainability goals and meeting net zero targets – all while providing the highest-quality product for consumers.”

Five ways going green can improve your bottom line: A guide for West Midlands SMEs

As sustainability becomes a central focus for businesses across the globe, small and medium-sized enterprises (SMEs) in the West Midlands are uniquely positioned to benefit from going green. Whether you're running a corner shop, a hairdressing salon, a manufacturing operation, or any other type of small business, sustainable practices can significantly enhance your bottom line. Here are five key ways that adopting green strategies can lead to financial gains. Reduced operational costs One of the most immediate and tangible benefits of going green is the reduction in operational costs. Energy efficiency, waste reduction, and resource conservation are all areas where small changes can lead to significant savings. For instance, simply switching to energy-efficient lighting can reduce electricity bills by up to 75 per cent—a substantial saving for any business, particularly for small retailers or service providers where margins can be tight. Additionally, the UK government offers incentives to help businesses transition to more energy-efficient operations, making it easier for SMEs to invest in these changes. Join Aston University’s workshop on 18 September and take advantage of a free energy assessment for your business. Learn practical steps to audit your energy use and uncover cost-saving opportunities tailored to your specific industry needs. Access to new markets and opportunities As the UK government and local authorities push for a greener economy, there are growing opportunities for businesses that align with these goals. SMEs that adopt sustainable practices may qualify for grants, tax reliefs, and other incentives designed to support green initiatives. For example, local councils in the West Midlands have programmes such as ‘BEAS and Decarbonisation Net Zero’ aimed at helping small businesses reduce their carbon footprint, which can be especially beneficial for almost all sectors where environmental impact is a growing concern. At the workshop, we’ll delve into the funding options and partnerships available to West Midlands SMEs committed to sustainability, helping you unlock new growth opportunities. Increased marketability Consumers are increasingly favouring businesses that demonstrate a commitment to sustainability. According to a study by Nielsen, 66 per cent of global consumers are willing to pay more for sustainable goods, and this trend is evident in the UK as well. By adopting green practices, SMEs in the West Midlands can enhance their brand reputation. This can translate to increased sales, customer loyalty, and even the ability to charge premium prices for sustainable products or services. In a competitive market, your environmental credentials can be a powerful differentiator. Attend Aston University’s workshop to learn from real-life success stories and see how businesses are already turning sustainability into a competitive advantage. Long-term resilience and competitiveness Sustainability isn’t just about immediate financial gains; it’s also about future-proofing your business. As regulations around carbon emissions and environmental impact become stricter, businesses that have already integrated green practices will find it easier to comply, avoiding potential fines and disruptions. For SMEs in sectors like manufacturing, where regulatory pressures are particularly high, adopting sustainable practices now can help ensure long-term competitiveness and resilience. A prime example of this shift is the NHS, which is actively working towards a Net Zero supply chain by 2045. The NHS is urging its suppliers to adopt sustainable practices, with a strong focus on reducing carbon emissions. Businesses that fail to align with these expectations risk losing contracts and falling behind competitors who are meeting these sustainability criteria. At the workshop, you'll learn more about sustainability strategy that can keep your business competitive and resilient in an ever-changing market. Enhanced employee engagement and productivity Increasingly, employees are seeking to work for companies that align with their personal values, including a commitment to sustainability. While this trend is more pronounced among larger companies, it’s also becoming relevant for small businesses, particularly those in industries where attracting and retaining talent is competitive. According to research, 74 per cent of employees feel more fulfilled when they work for a company that is making a positive impact on the environment. For small businesses, fostering a sustainable workplace can enhance employee morale, attract top talent, and reduce turnover rates. However, the degree to which this resonates can depend on your specific workforce. In sectors like tech, professional services, or among younger employees, sustainability is often a key consideration. On the other hand, in some more traditional industries, other factors like job security and compensation might be more important, though sustainability still adds value. Sign up for our workshop to discover how your small or medium business—regardless of sector—can implement effective sustainability practices and energy efficiency strategies to drive growth. This event is open to all SMEs across the West Midlands! Click here to register now. You'll also have the opportunity to book a free energy assessment on the spot and apply for match funding of up to £100,000 to make your business more energy efficient.

Aston University develops novel bone cancer therapy which has 99% success rate

Bioactive glasses, doped with gallium developed to create a potential treatment for bone cancer Lab tests have a 99 percent success rate of killing cancerous cells Method could also regenerate diseased bones. Bioactive glasses, a filling material which can bond to tissue and improve the strength of bones and teeth, has been combined with gallium to create a potential treatment for bone cancer. Tests in labs have found that bioactive glasses doped with the metal have a 99 percent success rate of eliminating cancerous cells and can even regenerate diseased bones. The research was conducted by a team of Aston University scientists led by Professor Richard Martin who is based in its College of Engineering and Physical Sciences. In laboratory tests 99% of osteosarcoma (bone cancer) cells were killed off without destroying non-cancerous normal human bone cells. The researchers also incubated the bioactive glasses in a simulated body fluid and after seven days they detected the early stages of bone formation. Gallium is highly toxic, and the researchers found that the ‘greedy’ cancer cells soak it up and self-kill, which prevented the healthy cells from being affected. Their research paper Multifunctional Gallium doped bioactive glasses: a targeted delivery for antineoplastic agents and tissue repair against osteosarcoma has been published in the journal Biomedical Materials. Osteosarcoma is the mostly commonly occurring primary bone cancer and despite the use of chemotherapy and surgery to remove tumours survival rates have not improved much since the 1970s. Survival rates are dramatically reduced for patients who have a recurrence and primary bone cancer patients are more susceptible to bone fractures. Despite extensive research on different types of bioactive glass or ceramics for bone tissue engineering, there is limited research on targeted and controlled release of anti-cancer agents to treat bone cancers. Professor Martin said: “There is an urgent need for improved treatment options and our experiments show significant potential for use in bone cancer applications as part of a multimodal treatment. “We believe that our findings could lead to a treatment that is more effective and localised, reducing side effects, and can even regenerate diseased bones. “When we observed the glasses, we could see the formation of a layer of amorphous calcium phosphate/ hydroxy apatite layer on the surface of the bioactive glass particulates, which indicates bone growth.” The glasses were created in the Aston University labs by rapidly cooling very high temperature molten liquids (1450o C) to form glass. The glasses were then ground and sieved into tiny particles which can then be used for treatment. In previous research the team achieved a 50 percent success rate but although impressive this was not enough to be a potential treatment. The team are now hoping to attract more research funding to conduct trials using gallium. Dr Lucas Souza, research laboratory manager for the Dubrowsky Regenerative Medicine Laboratory at the Royal Orthopaedic Hospital, Birmingham worked on the research with Professor Martin. He added: “The safety and effectiveness of these biomaterials will need to be tested further, but the initial results are really promising. “Treatments for a bone cancer diagnosis remain very limited and there’s still much we don’t understand. Research like this is vital to support in the development of new drugs and new methodologies for treatment options.” Notes to Editors Multifunctional Gallium doped bioactive glasses: a targeted delivery for antineoplastic agents and tissue repair against osteosarcoma Shirin B.

Industry and researchers call for action to tackle climate impact of organic, carbon-based chemicals

Call led by members of Supergen Bioenergy Hub, based at Aston University They highlight that carbon-based chemicals cannot be decarbonised but can be defossilised They want a transition to renewable carbon sources such as biomass, recycled carbon, and carbon dioxide. Director of Supergen Bioenergy Hub, Professor Patricia Thornley Industry experts and university researchers have joined together to ask the government to address the climate impact of organic, carbon-based chemicals. While demand for fossil fuels as energy is expected to fall in the coming decades, the petrochemicals sector is set to grow significantly according to experts and is set out in a 2018 report by the International Energy Agency. Members of the Supergen Bioenergy Hub which is based at Aston University and the Biomass Biorefinery Network believe the issue has yet to receive proper attention and is calling for a strategy that addresses this key component of our greenhouse gas emissions. They want a move to a more circular economy, managing supply and demand levels and transitioning away from fossil feedstocks which are raw materials required for some industrial processes. In their paper Carbon for chemicals How can biomass contribute to the defossilisation of the chemicals sector? they highlight that carbon-based chemicals cannot be decarbonised but can be defossilised through a transition to renewable carbon sources such as biomass, recycled carbon and carbon dioxide. Many products in modern society contain carbon such as pharmaceuticals, plastics, textiles, food additives, cosmetics, and cleaning products. These chemicals are derived from fossil feedstocks, so they are classed as petrochemicals. As a result, they contribute to global greenhouse gas emissions and climate change. Carbon is embedded in organic chemical products and released when they break down at end-of-life, for example through incineration. To address the emissions from carbon in chemicals and accelerate the development of bio-based chemicals, the group want a cross-party consensus to support a sustainable chemical system. Director of Supergen Bioenergy Hub, Professor Patricia Thornley, said: “We need to consider the UK’s future feedstock and chemicals production and use, and how it relates to net zero, agriculture, environment, economy, trade, and just transition policy objectives. There are opportunities here for the UK to lead the way on sustainable chemical production, but we need to carefully plan a roadmap for the transition, that delivers opportunities around jobs and the economy as well as sustainable greenhouse gas reductions. “There is a definite role for biomass here. But it is essential that any future use of biomass in the chemicals sector is underpinned by rigorous, trusted, and enforceable sustainability governance to build confidence, deliver sustainability benefits, and minimise negative impacts. That requires improvements in sustainability governance and regulation. “We think there are real economic and trade opportunities by the UK accelerating sustainable chemicals. At the moment bio-based chemicals, and chemicals derived from other renewable carbon sources, are not being expanded in the UK because there are no explicit incentives that prioritise them over fossil-based production.” The group argues that the UK has significant academic and industrial research expertise to underpin the development of sustainable bio-based products and could be a global leader in bio-based products and sustainability governance. They believe that to date little of this has manifested as UK-based scale-up and manufacturing, whilst there are numerous examples of UK-led research being scaled up elsewhere. The paper was delivered at a webinar on 7 August.
