• Rice straw could be a fuel of the future in rural Philippines

• Across Asia 300 million tonnes of rice straw go up in smoke every year

• New proposals includes scaling up harvesting system with straw removal, biogas-powered rice drying and storage and efficient milling.


An Aston University bioenergy researcher has been explaining how rice straw could be a fuel of the future in rural Philippines.


Dr Mirjam Roeder who is based at the University’s Energy & Bioproducts Research Institute (EBRI) is collaborating with the UK company Straw Innovations Ltd, Southeast Asian Regional Center for Graduate Study and Research in Agriculture (SEARCA) and Koolmill Systems Ltd to showcase their research.


The Food and Agriculture Organisation (FAO) states that rice is the number one food crop globally and 91% of it is produced and consumed in Asia. As a crop it is responsible for 48% of global crop emissions and for every kilogram of rice, a kilo of straw is produced.


Across Asia 300 million tonnes of rice straw go up in smoke every year when burnt after harvest, releasing emissions and air pollutants that triple risks of increased respiratory diseases and accelerate climate change.


To raise awareness of sustainable uses for rice straw Dr Roeder has travelled to the sixth International Rice Congress in Manila, Philippines to explain the potential of the emerging technology.

Rice straw is an underdeveloped feedstock and can be collected and digested to produce biogas, unlocking sustainable straw management options and renewable energy for farmers using anaerobic digestion (AD) from rice straw.


Dr Roeder has been working with Straw Innovations on their UK Innovate project demonstration facility in the Philippines, the Rice Straw Biogas Hub, which is scaling up a complete harvesting system with straw removal, biogas-powered rice drying and storage, together with efficient milling.


Craig Jamieson, Straw Innovations said: “The International Rice Congress is only held every four years and is a key event for coordinating and tracking progress in rice research.

“Our partnership with Aston University and SEARCA adds independent, scientific rigour to the work we do and amplifies our message to government policy makers. We are grateful to Innovate UK for their ongoing support through the Energy Catalyst Programme, which is accelerating our development.”


At the conference Dr Roeder has been explaining how independent environmental and social research can increase farmer incomes, equality of opportunity, food security and decarbonisation benefits.


She said: “Engaging with stakeholders and working in partnership across organisations is vital to the successful adoption of new technologies. I am delighted to have had the opportunity to host an event with our project partners at this prestigious conference, bringing the cutting-edge research of using rice straw for clean energy to the forefront of the rice research community and supporting the pathway to net zero.”


Dr Glenn B Gregorio, Center Director of SEARCA, added: "We are gaining insights into the environmental impact of rice straw utilisation and implementing policies to unleash its potential to empower us to make informed decisions that are instrumental to climate change mitigation and decarbonisation,"


Professor Rex Demafelis, University of the Philippines, is also working with SEARCA and is leading the project on life cycle analyses and measurements of rice straw greenhouse gas emissions. He said: “Rice straw is a valuable resource, and we are grateful to be part of this team which seeks to harness its full potential and promote circularity, which would ultimately contribute to our goal of reducing our greenhouse gas emissions.”

Aston University researcher develops new optical technique that could revolutionise medical diagnostics

New light technique could revolutionise non-invasive medical diagnostics Orbital Angular Momentum could be harnessed to improve imaging and data transmission through biological tissues Could eventually have potential to make procedures such as surgery or biopsies unnecessary. An Aston University researcher has developed a new technique using light which could revolutionise non-invasive medical diagnostics and optical communication. The research showcases how a type of light called the Orbital Angular Momentum (OAM) can be harnessed to improve imaging and data transmission through skin and other biological tissues. A team led by Professor Igor Meglinski found that OAM light has unmatched sensitivity and accuracy that could result in making procedures such as surgery or biopsies unnecessary. In addition it could enable doctors to track the progression of diseases and plan appropriate treatment options. OAM is defined as a type of structured light beams, which are light fields which have a tailored spatial structure. Often referred to as vortex beams, they have previously been applied to a number of developments in different applications including astronomy, microscopy, imaging, metrology, sensing, and optical communications. Professor Meglinski in collaboration with researchers from the University of Oulu, Finland conducted the research which is detailed in the paper “Phase preservation of orbital angular momentum of light in multiple scattering environment” which is published in the Nature journal Light Science & Application. The paper has since been named as one of the year’s most exciting pieces of research by international optics and photonics membership organisation, Optica. The study reveals that OAM retains its phase characteristics even when passing through highly scattering media, unlike regular light signals. This means it can detect extremely small changes with an accuracy of up to 0.000001 on the refractive index, far surpassing the capabilities of many current diagnostic technologies. Professor Meglinski who is based at Aston Institute of Photonic Technologies said: “By showing that OAM light can travel through turbid or cloudy and scattering media, the study opens up new possibilities for advanced biomedical applications. “For example, this technology could lead to more accurate and non-invasive ways to monitor blood glucose levels, providing an easier and less painful method for people with diabetes.” The research team conducted a series of controlled experiments, transmitting OAM beams through media with varying levels of turbidity and refractive indices. They used advanced detection techniques, including interferometry and digital holography, to capture and analyse the light's behaviour. They found that the consistency between experimental results and theoretical models highlighted the ability of the OAM-based approach. The researchers believe that their study’s findings pave the way for a range of transformative applications. By adjusting the initial phase of OAM light, they believe that revolutionary advancements in fields such as secure optical communication systems and advanced biomedical imaging will be possible in the future. Professor Meglinski added: "The potential for precise, non-invasive transcutaneous glucose monitoring represents a significant leap forward in medical diagnostics. “My team’s methodological framework and experimental validations provide a comprehensive understanding of how OAM light interacts with complex scattering environments, reinforcing its potential as a versatile technology for future optical sensing and imaging challenges.” ENDS https://www.nature.com/articles/s41377-024-01562-7 Light: Science & Applications volume 13, Article number: 214 (2024) August 2024 https://doi.org/10.1038/s41377-024-01562-7 Authors: Igor Meglinski, Ivan Lopushenko, Anton Sdobnov & Alexander Bykov About Aston University For over a century, Aston University’s enduring purpose has been to make our world a better place through education, research and innovation, by enabling our students to succeed in work and life, and by supporting our communities to thrive economically, socially and culturally.

Aston University researchers to explore using AI and fibre-optic networks to monitor natural hazards and infrastructures

Aston University is leading a new £5.5 million EU research project Will focus on converting fibre-optic cables into sensors to detect natural hazards Could identify earthquakes and tsunamis and assess civil infrastructure. Aston University is leading a new £5.5 million EU research project to explore converting existing telecommunication fibre-optic cables into sensors which can detect natural hazards, such as earthquakes and tsunamis, and assess the condition of civil infrastructure. The project is called ECSTATIC (Engineering Combined Sensing and Telecommunications Architectures for Tectonic and Infrastructure Characterisation) and is part of the Horizon Europe Research and Innovation Action (RIA), which aims to tackle global challenges and boost the continent’s industrial competitiveness. Converting telecom fibres into sensors requires new digital signal processing to overcome the limited data storage and processing capabilities of existing communication networks. To address this the project will use localised, high performance digital processing that will integrate artificial intelligence and machine learning. The researchers’ goal is to minimise algorithms’ complexity while providing extremely accurate real-time sensing of events and network condition. The new laser interrogation and signal processing technologies will be tested using existing fibre optic networks, including those underwater, in cities, and along railway infrastructure to assess their potential. Delivered by a consortium of 14 partners across seven countries, from academic and non-academic sectors, the research will start in February 2025 and will last three and a half years. The Europe-wide team will be led by Professor David Webb who is based in the Aston Institute of Photonic Technologies (AIPT). Professor Webb said: “There are more than five billion kilometres of installed data communications optical fibre cable, which provides an opportunity to create a globe-spanning network of fibre sensors, without laying any new fibres. “These traverse the seas and oceans - where conventional sensors are practically non-existent - and major infrastructures, offering the potential for smart structural health monitoring.” Professor Webb will be joined by fellow researchers Professor Sergei Turitsyn, Dr Haris Alexakis and Dr Pedro Freire.

EU-UK Trade Deal continues to stifle trade with 27% drop in exports since 2021

New report shows persistent stifling effects of the impact of the Trade and Cooperation Agreement on UK-EU trade relations Monthly data show a 27% drop in UK exports and a 32% reduction in imports to and from the EU between 2021 and 2023 Recommendations for policy interventions include to negotiate sector-specific deals, engage with individual EU countries, and work on reducing non-tariff barriers A comprehensive analysis by researchers at the Centre for Business Prosperity at Aston University reveals that negative impacts of the UK-EU Trade and Cooperation Agreement (TCA) have intensified over time. The new report, Unbound: UK Trade Post Brexit, also shows a 33% reduction in the variety of goods exported, with the agricultural, textiles, clothing and materials sectors most affected. To assess the impact of the UK-EU TCA, the authors analysed monthly import and export between the UK and the EU, from January 2017 to December 2023 and separated into pre- and post-January 2021 when the agreement came into force. The monthly data shows a 27% drop in UK exports and a 32% decline in imports from the EU. Lead author, Professor Jun Du of Aston University says: “The Trade and Cooperation Agreement introduced substantial barriers and there are ongoing and marked declines in the value and variety of UK exports and imports. Without urgent policy interventions, the UK’s economic position and place in the global market will continue to weaken.” The UK-EU TCA redefined trade and investment rules and market access between the UK and the EU. Since it came into force, the UK government has negotiated several trade agreements, but the EU remains the UK’s largest trade partner. Exports for most sectors have decreased since January 2021, although the impact is varied. Agrifood, textile and clothing and material-based manufacturing have been among the hardest hit, with substantial declines in both export value and the variety of products exported. At the same time, some sectors such as tobacco, railway and aircraft manufacturing have seen modest increases in varieties of products exported. On the import side, most sectors have shrunk in both value and variety, particularly agrifood products, optical, textile and material-based manufacturing. A few sectors, for example, ships and furniture, have demonstrated noticeable increases in import product variety. The large variations across different goods categories and EU trade partners underscore the uneven effects of Brexit and the TCA on UK-EU trade dynamics, highlighting the need to understand the nuances and come up with tailored strategies that address the unique challenges of each sector within the new regulatory environment. The researchers make recommendations, outlining how sector-specific negotiations, streamlining customs procedures with digital technologies and reducing regulatory divergence could mitigate some of the impacts. Dr Oleksandr Shepotylo, the report’s co-author says: “Our findings indicate a decoupling of the UK from key EU final goods markets, accompanied by a shift in UK supply chains toward geographically closer EU trading partners for exports and smaller countries for imports. “This shift raises concerns and underscores the urgent need for a strategic reconfiguration of UK supply chains to maintain competitiveness.” Professor Du continues: “The TCA has introduced considerable barriers to UK-EU trade, particularly through increased Non-tariff measures (NTMs). “Addressing these issues through targeted improvements to the TCA is crucial to ensuring that UK businesses remain competitive in the European market. A structured, multi-faceted approach is necessary.” To find out more about these findings, click here.
