Projects within the Silicates Research Unit have expanded the aesthetic and technical boundaries of ceramic materials and have had a significant impact on sustainable practices and materials within contemporary design. In response to increasingly stringent sustainable construction legislation, an AHRC Grant (£163,000) funded Binns and Bremner's development of a unique process for converting low-value mineral waste into high-value architectural products, avoiding reliance on non-replenishable materials.
Testing by the Environment Agency National Testing Laboratory has verified their innovative material meets British Standards for architectural materials (UK patent application, currently pending publication). It has also confirmed that the incorporation of Cathode Ray Tube (CRT) lead bearing glass (designated by the Environment Agency as hazardous waste) in the new material results in the lead content being safely encapsulated, offering a solution to the global problem of hazardous CRT waste glass recycling - allowing CRT glass to be re-classified as a safe raw material.
Research carried out by the University of Southampton has directly influenced the practice and behaviour of households, business, industry and government agencies. It has:
An innovative deep borehole disposal (DBD) concept for radioactive waste, pioneered at the University of Sheffield, resulted in significant impact on geological disposal strategy with an international reach. In the USA, our work contributed to a change in geological disposal strategy, with our concept described by the Director of Sandia National Laboratory as a "legitimate and a viable alternative [to the mined, engineered repository model] worthy of deeper consideration" [S1]. The Presidential Blue Ribbon Commission report on America's Nuclear Future recommended that DBD be taken forward to a practical pilot demonstration, now funded by the US Department of Energy (DOE) [S2]. Sheffield's work on DBD influenced Sweden's regulators and Environmental Court to reconsider approval of a mined repository by SKB. Our work has impacted on the UK approach to waste management, with DBD now included in the Nuclear Decommissioning Authority (NDA) [S3] bid to accelerate the Government's Managing Radioactive Waste Safely programme.
The impact of the research by the Caledonian Environment Centre can be demonstrated by the shift in Scotland's recycling rates from 4% in 1998 when the Centre was established, to 40% in 2011. The Centre's research methods were embedded in assessment tools which led to Scottish Councils being provided with £64m of additional annual funding. The Remade Scotland programme, hosted and developed by the Centre, between 2000 and 2010, delivered change as the first recyclate UK market development programme, and was further developed across the UK: two years later leading to the establishment of Waste Resources Action Programme (WRAP).
Research at Loughborough University during the REF period (and extending back at least three decades beyond that) has had a significant impact on national and international policy decisions governing the management of radioactive waste, one of the Grand Challenges facing society. The Unit's research ranges from deep geological disposal to abatement of marine discharges and remediation strategies for industrial radioactive waste, the latter safeguarding the competitiveness of the oil & gas and mineral processing sectors. This input has been crucial for revising the new Environmental Permitting Regulations and International Basic Safety Standards. Many of the Unit's doctoral graduates occupy important decision-making roles at key organisations such as the Nuclear Decommissioning Authority (NDA), Sellafield, Environment Agency, CEA (France) and the International Atomic Energy Agency (IAEA).
Wastes management represents a major global environmental challenge. In the early 2000s Defra recognised that the UK's emphasis needed to change from managing waste to preventing it arising, and that Local Authorities must be equipped to produce cost-effective waste reduction plans. To this end, WRAP (Waste and Resources Action Programme) financed a major Local Authority training programme involving the Centre for Sustainable Wastes Management (CSWM) due to its track record of research expertise. Evaluation of this training demonstrated that over 90% of 204 delegates (from 33% of Local Authorities) developed a deeper understanding of waste prevention and 41% consequently upgraded their plans, embedding sustainable practice into their organisations and reducing arisings. The ultimate impact of this has been to save Local Authorities money and reduce the amount of waste going to landfill.
The research of Prof Jim Frederickson and the Integrated Waste Systems Research group at The Open University (OU) has impacted industrial partners and government agencies in developing a sustainable approach to waste processes and treated products. In particular they have developed the biodegradability tests (DR4 and BM100/BMc) used extensively for the evaluation of Mechanical and Biological Treatment (MBT) waste plants, and also the Residual Biogas Potential (RBP) test for determining the stability of anaerobic digestates, which forms part of the BSI PAS110: 2010 specification. This work is a significant contribution to the development of sustainable waste management practices in the UK.
The research groups of Professor Laurence Harwood and Dr Michael Hudson (now retired) at the University of Reading have developed new and highly selective extractants for spent and reprocessed nuclear fuels. These novel extractants remove specifically the components in nuclear waste that have the highest levels of long-term radioactivity. The extracted components (minor actinides) may subsequently be converted — "transmuted" — into elements with greatly reduced radioactivity. Storage times for high-level nuclear waste can thus be reduced by a factor of a thousand, typically from 300,000 to 300 years. This significant advance in the management of nuclear waste means that next-generation nuclear power production will be safer, more economical and more sustainable, as well as increasing the wider acceptance of nuclear power as a viable alternative to fossil fuels. The newly-developed extractants are now available commercially through TechnoComm Ltd.
The demand for biofuels and alternative energies is increasing globally as a sustainable source of energy is sought for the future. Energy from crops is no longer a viable option due to the increase in wheat prices. Scientists at the BEST Research Institute have managed to bridge the gap by using novel and unique microwave systems for converting waste (biomass, food, animal) into energy. Our advances in this area have generated considerable interest from both national (e.g., United Utilities PLC, Balfour Beatty PLC, Biofuels Wales Ltd, Stopford Projects Ltd, Longma Clean Energy Ltd) and international (e.g., RIKEN-Japan, Fraunhofer-Germany, Sairem-France, Acondaqua-Spain, Ashleigh Farms-Ireland) companies. This has resulted in several collaborative, funded projects leading to industrial adoption of our microwave technologies.
Accelerated Carbonation Technology (ACT) is an innovative solution to several key environmental issues - CO2 emissions to the atmosphere, sustainable use of resources and the reliance on use of virgin stone for construction. ACT rapidly stabilises industrial waste recycling it into valuable aggregate, thereby reducing the amount going to landfill. ACT simultaneously captures the greenhouse gas CO2, via the rapid production of carbonate, which solidifies the waste into a hardened product. ACT has been commercialised through two spin-out companies leading to the first commercial production of carbon negative concrete blocks, taking hazardous waste from the bottom to the top of the waste hierarchy.
