Turning livestock waste into sustainable fertiliser with hydrothermal technology

August 14, 2025 No Comments

A new initiative is enabling farmers to optimise the use of livestock manure and nutrients as fertiliser, helping to reduce costs and environmental impact. The project, titled ‘Nutrient Utilisation and Recovery through Supercritical Extraction’, or NURSE, is being developed by a consortium of collaborators including Kairos Carbon Limited (lead), Cranfield University, Royal Agricultural University and the UK Agri-Tech Centre. It is a part of Defra’s Farming Innovation Programme, delivered in partnership with Innovate UK. NURSE is focused on developing hydrothermal technology to process livestock waste, recovering valuable nutrients and producing carbon-negative, non-leaching fertiliser. The process also enables permanent carbon sequestration, offering a sustainable solution for farmers. Megha Raghavan, CEO of Kairos Carbon Limited, said:“It is critical that we find ways to turn wet organic wastes from a problem into a resource. This technology has the potential to prevent environmental contamination, fight nutrient depletion and remove billions of tonnes of carbon dioxide from the atmosphere, making it a powerful tool in the fight against climate change.” The UK generates approximately 140 million tonnes of livestock waste every year, most of which is spread on farmland. However, less than half of the nutrients applied, such as phosphorus, are absorbed by crops when livestock waste is spread on land. At the same time, farmers are facing rising fertiliser costs, while fertiliser resources like phosphorus are being depleted. This project offers a sustainable solution by removing carbon before fertiliser is applied, helping to significantly reduce emissions. Its non-leaching properties also ensure that more nutrients are absorbed by the plants, reducing waste and lowering costs. Impacts for agriculture The hydrothermal technology developed offers direct benefits to farmers by recovering critical nutrients and materials from livestock waste in a condensed form. This enables the targeted use of low-leaching, sustainable fertilisers that help to reduce costs and improve crop yields. The technology will also allow for more effective waste management, decrease organic pollutants and capture carbon for storage, all while being energy neutral. These benefits also directly meet the UK’s requirements to improve the management of the livestock waste produced across England. Dr Stuart Wagland, Reader in Energy and Environmental Chemistry at Cranfield University, said: “Developing novel thermochemical processes to manage challenging wet wastes, dealing with emerging contaminants and recovering nutrients will have a significant impact across the UK and we are excited to be involved in this project.” Beyond directly benefiting farmers, Kairos also aims to further reduce emissions from UK agriculture and prevent pollutants and excess nutrients from entering water sources, helping to minimise the environmental impact of fertiliser use. The technology also addresses air pollution from livestock waste and other sources of agricultural emissions. Dr Karen Rial-Lovera, Associate Professor in Agriculture and Dean of Agricultural Science and Practice at the Royal Agricultural University, said: “This innovation seeks to support our growing need for sustainable nutrient management in agriculture. By repurposing waste products into a targeted fertiliser, the project has the potential to reduce contamination, waste and improve crop yields.” In addition, Kairos’ solution will create and safeguard hundreds of skilled jobs across its supply chain like farming and agronomy, which support rural communities, to chemical engineering in fabrication and maintenance. This technology is scalable and can expand to additional industries, including sewage sludge, municipal waste and hazardous chemicals. This expansion offers the potential to remove more emissions and pollution whilst making more nutrients available for agriculture. Charlie Bowyer, Farm Technology Specialist at the UK Agri-Tech Centre, said: “Manure is an invaluable source of on-farm nutrients in livestock systems, but it is not without its challenges. Challenges around cost-effective and sustainable manure and slurry storage and point and diffuse air and water pollution are all serious issues facing farms producing manure. Furthermore, the east-west arable/livestock divide has led to an asymmetry in the availability of organically-derived nutrients in farming systems. Technologies to effectively process manures to eliminate storage issues whilst adding value by concentrating or stripping nutrients are sorely needed and this project takes a step towards developing a fascinating process to achieve just this.” If you want to learn more about the NURSE project or other UK Agri-Tech Centre projects, please get in touch via [email protected]

Are legumes the future of plant-based proteins in the UK?

August 6, 2025 No Comments

Plant-based diets are on the rise, with vegan and vegetarian options now a staple on supermarket shelves. However, to meet the environmental concerns of those who are changing their diets and opting for plant-based alternatives, the food industry must encourage UK farmers to grow more protein-rich crops. In this article, Dr Réka Haraszi, Innovation Lead – Food & Drink at the UK Agri-Tech Centre, examines the growing importance of legumes, a popular plant protein. Why do plant-based proteins matter? Protein is essential for a balanced diet and is traditionally sourced from animal products like meat, dairy and eggs. Today, consumer demand is shifting towards plant-based and ‘flexitarian’ diets because of sustainability concerns around the consumption of meat. This shift opens new opportunities for plant-based alternatives, but we must ensure that we are not shifting the problems arising from the production of animal products to plant-based alternatives. The UK farming sector must adapt to be able to meet the demand for raw materials needed for plant-based food production. To make sure that alternative protein sources are sustainable, an integrated approach must be taken that considers the wider supply chain, consumer expectations and public health requirements. Examples of this include: Low volume crop proteins Insect and mycoproteins Technologies like precision fermentation and cellular agriculture Scalable plant-based protein sources Increased demand for plant proteins The demand for plant-based protein is continuing to grow, driven by the lower environmental impact and perceived health benefits compared to conventional animal protein. The global plant protein market shows a compound annual growth rate (CAGR) of 8-9% (UK market 8.25% CAGR) for the coming years, offering great potential for innovation. The uptake of plant proteins by the food industry is growing for both animal and human consumption and the right balance between these markets will help avoid waste and improve the quality of food and feed. These factors are already transforming the protein market. What are legumes? Legumes are a family of plants – including beans, peas and lentils – that are nutrient rich and can be consumed fresh or fried (as pulses). In the UK, crops like beans, faba beans and lupins are traditionally grown mostly for animal feed, specialist food processing (canned/frozen peas) or for export. The UK also imports other legume crops like chickpeas, peanuts, lentils, soybeans and dried peas for food processing. However, these are often sourced from areas of deforestation or use unsustainable production systems.

Agri-tech in action: Bowhill farm walk

July 31, 2025 No Comments

Farmers were able to see agri-tech in action during a farm walk on the Bowhill Estate, near Selkirk. Organised by the UK Agri-Tech Centre, more than 40 people attended the event on July 29 at the 6,500 hectare estate in the Scottish Borders, which is one of our satellite farms. With companies such as Ritchie showcasing its beef and lamb monitoring technology, Smaxtec talking about its bolus and health monitoring options, Soil Essentials demonstrating its Skai Sprayer allowing it to directly target weeds within the pasture leys and Smartbell demonstrating its health monitoring tags in cattle used for the early detection of disease, farmers were able to see agri-tech working within a farm setting. We had the pleasure of welcoming newly voted in chair of The Scottish Association of Young Farmers Clubs (SAYFC), Jillian Kennedy, who gave an insight into the work the Young Farmers group are doing to raise awareness nationwide on the positive future of Scottish Farming using the latest innovations. The event also saw a specially branded JCB Fastrac which had the My Name’5 Doddie livery on it. This was to raise awareness of the charity set up in memory of Scottish rugby legend Doddie Weir who passed away of motor neurone disease. Rob Morrison, the UK Agri-Tech Centre Head of Farms, said: “This event was about connecting farmers with agri-tech and showing what is coming down the line. Crucially, it was the smaller conversations that took place which are of real value and allow farmers to shape the sort of agri-tech they want to see and which will make a real difference.” Bruce McConachie, Head of Industry Development for Quality Meat Scotland (QMS), also spoke at the event and emphasised the role agri-tech has to play in a constantly evolving agricultural sector. Bruce said: “It is about understanding that agriculture has a key role to play, as long as we are relaying it in a consistent format. That is one of the key challenges in all of this.” For Bowhill farm manager Sion Williams, emerging technology was changing the way they farmed an estate which encompassed huge sheep flocks, a suckler herd, a deer farming enterprise and a biogas unit. He said working with the UK Agri-Tech Centre was helping bridge the wider challenge of getting key performance data from agri-tech trials ‘into the hands of farmers’ so it could make a tangible difference at farm level.

July 9, 2025 No Comments

The UK Agri-Tech Centre’s Dairy Technical Manager, Mike Jones, takes us on a tour of his favourite dairy cows at the South West Dairy Development Centre, to celebrate Cow Appreciation Day (July 9). Mike helps look after a 200-cow dairy unit in Shepton Mallet, owned and managed by the UK Agri-Tech Centre’s farming partner, Steanbow Farms. As part of Cow Appreciation Day, Mike was keen to share a few interesting facts about his beloved dairy cows and what they get up to on a normal day. Mike said: “The cows in the all-year round calving herd make their own decisions and choose when they eat, drink, lie down and rest. They can visit one of the three milking robots to receive some cow cake and be milked. Currently, the herd is achieving a Lact average of 11,300 L at 4.2% BF 3.3% P, which is how much the average cow produces in lactation of 305 days, before she has a six-week holiday prior to calving again. The cows live in a clean, relaxed, calm environment and their fertility rate is excellent, with a pregnancy rate of 35%, well above the national industry standard.” To join Mike on his virtual tour around the farm, click the link to watch the video and meet Mike’s favourite cows.

Derisking the transition to regenerative agriculture using systems thinking

June 19, 2025 No Comments

Regenerative agriculture plays a vital role in improving soil health, enhancing biodiversity and ensuring the long-term sustainability of food production. However, many farmers face significant barriers, including financial risks, knowledge gaps and uncertainty about short-term economic returns during the transitions. A recent event hosted by the UK Agri-Tech Centre and EIT Food brought together stakeholders from across the supply chain in an Open Innovation Forum focused on how to de-risk the transition to regenerative agriculture. The event highlighted the power of systems thinking and collaborative innovation in overcoming barriers and accelerating change. The focus areas of the forum: Reducing risks for farmers transitioning to regenerative agriculture Building a stronger support network by integrating technology and engaging stakeholders across the supply chain Evolving perspectives Open discussions and collaborative thinking throughout the forum altered the perceptions of the attendees around who holds responsibility for the transition to regenerative agriculture. While farmers were initially seen as the primary drivers of change, participants left with a broader understanding that a holistic, systems-thinking approach that involves the entire agrifood supply chain is essential. A systems-wise approach to change Roundtable discussions provided a platform to share knowledge and ideas on how the agrifood supply chain can collaborate to support the transition to regenerative agriculture. They focused on the use of technology, policy and collaboration to overcoming barriers to adoption. Throughout the day four key themes rose: De-risk the transition: The financial and operational risk of transitioning should not fall solely on farmers but rather shared across the supply chain. Proposed solutions included transition funds and retail incentives to ease the burden. Data standardisation: Data should focus on measuring the impact of transitioning, with artificial intelligence and automation to help simplify data handling, create data frameworks and support compliance. Behavioural changes: Education, training and clear communications about the benefits of regenerative agriculture is needed across the supply chain, from consumers to policymakers, to build understanding and momentum. Holistic approach: Long-term success requires a holistic approach with buy-in from the entire supply chain to support the entire ecosystem from biodiversity and soil health to farmers and food quality. Proposed solutions include benchmarking and focusing on success metrics rather than just crop yields. Open innovation breaks down traditional silos to enable knowledge and ideas to flow freely. It fuels faster, more creative solutions and empowers businesses to turn ideas into real-world impact. More opportunities are needed for open collaboration across the sector to drive forward sustainable solutions and turn these initial discussions into actions.

Plasma technology in agriculture

May 6, 2025 No Comments

Plasma technology within the agri-tech sector is a sustainable, chemical-free tool with the potential to improve crop production, plant health and fertiliser systems. Already widely applied in sectors such as healthcare, manufacturing and electronics, plasma is now being investigated for its potential to deliver environmental and economic benefits across agriculture. Plasma is often referred to as the fourth state of matter — a charged, energetic state formed when gases like air are exposed to an electric field. When gas is energised to a certain point, electrons are stripped from atoms, resulting in a mix of free electrons and ions. This makes plasma electrically conductive and responsive to magnetic fields. Natural examples of plasma include lightning and the Northern and Southern Lights. In agriculture, these can be used to treat seeds, reduce pathogens, promote plant growth or even synthesise nitrogen fertiliser. Most notably, plasma-activated water (PAW) and on-farm plasma-based fertiliser systems are emerging as viable alternatives to conventional seed treatments, pesticides and nitrogen fertilisers. The UK Agri-Tech Centre is currently supporting innovation in this space through research, business engagement and technology demonstration, working with companies and consortia aiming to bring plasma closer to widespread on-farm application. Plasma in practice While plasma technology remains in the early stages of adoption within agriculture, interest is growing. Cold plasma, generated at low temperatures, is being explored for its ability to enhance plant growth and resilience. By treating seeds and crops with cold plasma, farmers can potentially reduce the need for chemical fertilisers and pesticides. PAW, created by exposing water and ambient air to cold plasma, has shown promise as a natural, residue-free treatment for seeds and crops. Its antimicrobial properties can support disease control, while its ability to stimulate seed germination and root growth positions it as a potential alternative to chemical inputs. Similarly, new systems for producing fertiliser directly on farm using plasma and slurry are being explored as part of a shift towards circular, lower-emission production methods. These technologies align with wider ambitions to reduce reliance on imported fertilisers and improve the sustainability of nutrient management. Industry innovation The potential for plasma in agriculture is being actively explored by several UK-based organisations, some of which are working in collaboration with the UK Agri-Tech Centre and Innovate UK. Looking ahead As pressures mount to reduce synthetic input use, lower emissions, and improve soil health, plasma technology offers a potential route to achieving more sustainable and circular agricultural systems. However, to move from promise to practice, greater focus will be required on technical optimisation, integration with existing farm infrastructure and clearer regulation. Despite these opportunities, several technical, economic and regulatory challenges remain. Plasma systems are often energy-intensive and many have yet to be proven at scale in real-world agricultural settings. Further work is needed to understand the biological interactions, refine delivery mechanisms and build robust, science-led regulatory frameworks to support commercialisation. With targeted research, continued innovation and support from industry networks, plasma-based solutions could play a valuable role in enhancing the resilience and sustainability of UK agriculture in the years to come.
