CPUT and the South African Biogas Industry Association (SABIA) recently held the first SABIA-CPUT Agro-Industrial Biogas Training Seminar and Study Tour to strengthen capacity-building within South Africa’s growing biogas sector.
Associate Professor and Head of Research in the Department of Biotechnology, Vincent Okudoh, saw it fit to bring the training to CPUT to bridge the knowledge gap between theory, policy, and practical implementation by bringing together experts, practitioners, researchers, and industry stakeholders.
The core purpose of the three-day event, which was held at the South African Renewable Energy Technology Centre, was to provide a comprehensive introduction to agro-industrial biogas technology from sector development trends, digester biology and engineering to substrate management, operational monitoring, environmental legislation, and best practices within the South African context.
The workshop fostered a highly interactive learning environment during presentations, discussions, and the practical site visits. Reflecting on the event, Okudoh said: “What stood out most was the diversity of attendees, from academia and research institutions to industry players and emerging biogas practitioners. This mix created rich, insightful conversations and a strong spirit of collaboration. The facilitators delivered complex topics in an accessible manner, and participants were eager to ask questions, share experiences, and explore practical solutions relevant to their work.”
He also noted that the end goal was to equip participants with practical, evidence-based insights that will support the development, optimisation, and future scaling of biogas projects across the country. “Ultimately, the organisers hoped to cultivate a knowledgeable community of practitioners who can drive innovation, support national sustainability goals, and contribute to a more resilient renewable energy sector.”
The seminar featured presentations on the status quo of the biogas sector in South Africa and the way forward for sector development, “which were particularly powerful, as they contextualised the challenges and opportunities facing the industry”. There were also technical sessions, some focusing on digester biology, substrate suitability, process monitoring, and engineering parameters, which were highly informative and provided participants with practical tools applicable to real-world systems.
The event also featured a study tour to the Cape Town Biogas Plant in Athlone and the CPUT Winery Waste Biogas Unit at the Agricultural Research Council, Stellenbosch. “Seeing operational systems firsthand helped bridge the gap between theory and practice, giving participants invaluable exposure to real operational challenges and innovations. Networking moments throughout the seminar were also extremely meaningful, allowing participants to forge new professional connections that may support future collaborations and project development,” Okudoh remarked.
He added that the workshop demonstrated that biogas is more than a technical solution; “it is a strategic opportunity for sustainable development, waste management, energy security, and innovation in South Africa”. The insights gained highlight the importance of interfaculty programmes such as Applied Science and Engineering and interdisciplinary collaboration and continuous capacity-building as the sector evolves. He said this is in line with the Vision 2030 Framework for One Smart CPUT, Focus Area 6: Smart Engagement and strong links with quintuple helix partners.
Okudoh also urged the CPUT community to remain engaged with renewable energy research and industry developments, as platforms like this training seminar play a crucial role in shaping the future of the green economy. He also extended appreciation to the industry and institutional partners: SABIA, Bio2Watt, Cape Town Biogas, Global Energy, ARC, Vaal University of Technology, and Stellenbosch University for contributing to the success of the 2025 Biogas Training Workshop.

Numerous presentations on different topics from different fields were provided, Prof Jessy Van Wyk and Melissa Rossouw made a presentation on the Indigenous Knowledge Documentation Centre. Dr Vusi Mshayisa and Tina Bebe from the Food Science and Technology Department talked about how edible insects, such as Mopani worms, madzhulu, and thongolifa, are not only a traditional delicacy in parts of South Africa but also a powerhouse of nutrition.
His groundbreaking research in the field of edible insect proteins has set him apart as a pioneer in sustainable food science. By focusing on the extraction, characterisation, and application of proteins derived from Black Soldier Fly larvae, Mshayisa is contributing innovative solutions to the global food security crisis. His research delves into these proteins' nutritional, techno-functional, and structural properties, using advanced tools like Fourier-transform infrared spectroscopy, differential scanning calorimetry , and multivariate analysis techniques. “These insights are helping to shape the future of alternative protein sources, offering sustainable and nutritious options that reduce the reliance on traditional animal-based proteins,” he noted.
Maleka said as an engaged institution, CPUT is committed to conducting relevant and responsive research with impact to address socioeconomic priorities and challenges. Maleka stated that the seminar was part of Activity 4: Develop and facilitate activities and appropriate systems to promote and support research uptake under the University Capacity Development Grant Project 5 for Staff Development Research.
