• 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 method of making lengthy privacy notices easier to understand

It has been estimated it would take 76 days per year to fully read privacy notices New method makes notices quicker and easier to understand by converting them into machine-readable formats Team designed a JavaScript Object Notation schema which allowed them to validate, annotate, and manipulate documents. An Aston University researcher has suggested a more human-friendly way of reading websites’ long-winded privacy notices. A team led by Dr Vitor Jesus has developed a system of making them quicker and easier to understand by converting them into machine-readable formats. This technique could allow the browser to guide the user through the document with recommendations or highlights of key points. Providing privacy information is one of the key requirements of the UK General Data Protection Regulation (GDPR) and the UK Data protection Act but trawling through them can be a tedious manual process. In 2012, The Atlantic magazine estimated it would take 76 days per year to diligently read privacy notices. Privacy notices let people know what is being done with their data, how it will be kept safe if it’s shared with anyone else and what will happen to it when it’s no longer needed. However, the documents are written in non-computer, often legal language, so in the paper Feasibility of Structured, Machine-Readable Privacy Notices Dr Jesus and his team explored the feasibility of representing privacy notices in a machine-readable format. Dr Jesus said: “The notices are essential to keep the public informed and data controllers accountable, however they inherit a pragmatism that was designed for different contexts such as software licences or to meet the - perhaps not always necessary - verbose completeness of a legal contract. “And there are further challenges concerning updates to notices, another requirement by law, and these are often communicated off-band e.g., by email if a user account exists.” Between August and September 2022, the team examined the privacy notices of 50 of the UK’s most popular websites, from globally organisation such as google.com to UK sites such as john-lewis.com. They covered a number of areas such as online services, news and fashion to be representative. The researchers manually identified the notices’ apparent structure and noted commonly-themed sections, then designed a JavaScript Object Notation (JSON) schema which allowed them to validate, annotate, and manipulate documents. After identifying an overall potential structure, they revisited each notice to convert them into a format that was machine readable but didn’t compromise both legal compliance and the rights of individuals. Although there has been previous work to tackle the same problem, the Aston University team focused primarily on automating the policies rather than data collection and processing. Dr Jesus, who is based at the University’s College of Engineering and Physical Sciences said: “Our research paper offers a novel approach to the long-standing problem of the interface of humans and online privacy notices. “As literature and practice, and even art, for more than a decade have identified, privacy notices are nearly always ignored and ”accepted” with little thought, mostly because it is not practical nor user-friendly to depend on reading a long text simply to access, for example a news website. Nevertheless, privacy notices are a central element in our digital lives, often mandated by law, and with dire, often invisible, consequences.” The paper was published and won best paper at the International Conference on Behavioural and Social Computing, November 2023, now indexed at IEEE Xplore. The team are now examining if AI can be used to further speed up the process by providing recommendations to the user, based on past preferences.

Aston University optometrists take up global industry association roles

Professor Nicola Logan has been named a global myopia management ambassador by the World Council of Optometry Dr Debarun Dutta is the new academic chair of the British Contact Lens Association Aston University School of Optometry is ranked in the top 10 for research in the Complete University Guide 2024 Professor Nicola Logan and Dr Debarun Dutta from Aston University’s School of Optometry have both been appointed to major roles within optometry industry associations. The School of Optometry is regularly ranked highly by both leading national ranking publications and in annual student-led surveys. This includes a top 10 ranking for research and a top five ranking for graduate prospects in the Complete University Guide 2024, and first in the UK for student/staff ratio in health professions (optometry) in the Guardian University Guide 2024. Professor Logan, professor of optometry and physiological optics and deputy head of the School, has been named a global myopia management ambassador by the World Council of Optometry (WCO). She is one of four new ambassadors named by the WCO in collaboration with CooperVision, a leading myopia management company. WCO and CooperVision have developed a myopia management online tool which reflects WCO’s global standard of myopia care. In March 2024, Professor Logan presented her inaugural lecture at Aston University on her research into the nature of myopia, the growing evidence base on strategies to control eye growth in children and translation of these findings to clinical practice. She said about her appointment as an ambassador: “I am thrilled to be appointed as the global myopia management ambassador for the World Council of Optometry. This role provides me with a valuable platform to advance the recognition of myopia as a significant public health concern and to facilitate the translation of research into effective, evidence-based clinical practice strategies for children with myopia.” Dr Dutta, a lecturer in optometry, has been appointed the new academic chair of the British Contact Lens Association (BCLA). He will lead the BCLA’s academic output, including offering guidance and advice to the BCLA council about scientific and academic elements of contact lenses. Dr Dutta will initially work alongside current academic chair, Professor James Wolffsohn, Aston University’s head of optometry, who is currently on sabbatical from the University, before taking over when Professor Wolffsohn steps down in 2025. Dr Dutta said: “I am hugely excited at the prospect of delivering academic provision of the British Contact Lens Association, with a specific focus on a highly prestigious conference programme as we grow our reputation as a global leader in contact lens and anterior eye education. This is a rare opportunity to work alongside our association members, fellows, trustees, global ambassadors and volunteers inspiring a new era for the BCLA, and to support our growth and development ambitions through delivery of educational activities within the contact lens and anterior eye specialism.”
