Working towards sustainable agriculture, Aston University has embarked on the CoolRun project, an ambitious initiative aimed at addressing the persistent challenge of international crop waste, especially in sub-tropical climates. Fueled by a grant of £241,075 from Innovate UK, Aston University is set to redefine farming practices and combat food wastage in Malawi, Southern Africa. This groundbreaking solution, powered by digital twins, holds the potential not only to reshape farming techniques but also to serve as a blueprint for global agricultural sustainability.

The Challenge of Crop Waste in Malawi

Malawi, like many regions with suboptimal electricity infrastructure, grapples with significant hurdles in preserving harvested crops. Astonishingly, up to 50% of crops in Malawi go to waste due to the lack of a reliable cold supply chain for perishable goods. The CoolRun project emerges as a response to this challenge, aiming to develop a sustainable solution that operates effectively in the face of unreliable electricity and rising costs of fossil fuels.

Innovation at the Core: Sustainable Cool Boxes and Digital Twins

At the heart of the CoolRun project is the development of a mobile refrigerated box cooled by a phase-change material. This innovative material has the unique ability to release or absorb sufficient energy to maintain optimal temperatures for storing fruits and vegetables. What sets this project apart is the integration of digital twin technology, a virtual replica of the physical system that enables precise design, monitoring, and optimization.

How Digital Twins are Evolving Agricultural Practices

Digital twins, originally conceptualized in manufacturing and industrial contexts, are increasingly finding applications in diverse fields, including agriculture. In the CoolRun project, a digital twin of the sustainable cool box design will be created at Aston University. This virtual counterpart serves as a dynamic tool to inform the final design, providing insights into the behavior and performance of the physical system.

The evolving role of digital twins in agriculture extends beyond design optimization. Digital twins enable real-time monitoring and analysis of agricultural processes, allowing for proactive decision-making. In the context of the CoolRun project, the digital twin will play a crucial role in ensuring the efficiency and effectiveness of the refrigeration system, ultimately contributing to the reduction of post-harvest crop wastage.

Addressing Energy Challenges with Solar Power

Recognizing the unreliable electricity supply in Malawi, the CoolRun project incorporates solar power as a sustainable energy source. The project aims to deploy a solar-powered refrigeration unit that not only cools the phase-change panels but also operates a central cool air blaster. This integrated approach leverages renewable energy to address the energy challenges posed by traditional methods reliant on fossil fuels.

Real-time Monitoring and Cloud Database Integration

The CoolRun project introduces a dynamic element to the traditional cold supply chain by incorporating real-time monitoring through a cloud database. After the crops are cooled at a central location, they are transferred to mobile CoolRun pods. These pods are equipped with technology that allows both suppliers and customers to monitor their location and temperature remotely. This transparency in the supply chain ensures efficiency and traceability, key elements in the journey toward sustainable agriculture.

Societal Impact: Empowering Communities and Fostering Gender Equality

In rural Malawi, where farming is predominantly subsistence-based and often a female occupation, the CoolRun project extends its impact beyond the technical realm. Farmers, who traditionally sell their produce directly or through resellers, face limitations in accessing higher-paying markets due to the lack of chilled crops. By enabling chilled crops to reach more lucrative markets, the CoolRun project aims to empower women in agriculture and positively impact gender and unrepresented groups.

Dr. Abed Alaswad, a senior lecturer in engineering and technology on the research team, emphasizes the broader impact of the project. Once operational, the project is expected to have the potential to cut waste from 50% to less than 5%, fostering economic development and providing new opportunities for women in agriculture.

Scaling Globally: A Sustainable Model for Agriculture Worldwide

While the initial focus is on Malawi, the researchers believe that the CoolRun technology can be adapted and implemented across diverse regions globally, including the Americas, Africa, and the Far East. The scalability of this technology, combined with its potential to reduce strain on local electricity grids, positions it as a versatile solution for global agricultural challenges.

The success of the CoolRun project could catalyze similar initiatives worldwide, ushering in a new era of agricultural innovation and sustainability. The integration of digital twins and sustainable energy sources sets a precedent for the future of agriculture, demonstrating how technology can be harnessed to address critical challenges in food production.

Expanding the Impact: Global Adoption and Future Applications

As the CoolRun project unfolds over the next two years, its success could mark a paradigm shift in agricultural practices, emphasizing the importance of technological innovation in building a resilient and sustainable future for global agriculture. The potential for digital twins to optimize various aspects of farming, from resource utilization to crop management, opens new frontiers in precision agriculture.

The global adoption of sustainable cool boxes powered by digital twins holds the promise of reducing food wastage on a massive scale. Beyond Malawi, regions grappling with similar challenges in preserving harvested crops could benefit from this innovative solution. The scalability and adaptability of the CoolRun technology position it as a frontrunner in the quest for sustainable agricultural practices worldwide.

Conclusion: A Sustainable Future for Agriculture

In conclusion, Aston University’s CoolRun project stands as a beacon of innovation, showcasing the potential of technology to transform agriculture sustainably. By addressing the challenges of crop waste through a combination of sustainable energy, real-time monitoring, and digital twin technology, the project not only offers a solution for Malawi but presents a scalable model for global adoption.

The evolving role of digital twins in agriculture opens new avenues for precision farming and resource optimization. As the CoolRun project progresses over the next two years, its success could mark a paradigm shift in agricultural practices, emphasizing the importance of technological innovation in building a resilient and sustainable future for global agriculture. The potential for this sustainable solution to be applied globally signals a new era in the fight against food wastage, heralding a future where technology and agriculture converge for the greater good of humanity.
