A recent study published in Biotechnology Advances [1] investigated the potential of thermophilic anaerobic digestion (AD) for converting cow manure into biogas, a clean burning fuel. The study focused on two key factors influencing the efficiency of this process: temperature and temperature fluctuation. Why Thermophilic Digestion? Thermophilic AD operates at high temperatures (around 50-60°C) compared to mesophilic AD (25-40°C). While thermophilic processes require more energy to maintain temperature, they offer several advantages: Faster Breakdown: Higher temperatures accelerate the breakdown of organic matter in manure, leading to quicker biogas production. Pathogen Elimination: Thermophilic conditions effectively eliminate pathogens and weed seeds present in manure, making the resulting digestate safer for use as fertilizer. Finding the Optimal Temperature The study compared the performance of AD at 50°C and 60°C. Interestingly, the researchers found that 50°C resulted in higher methane production rates across various conditions. This suggests that there might be diminishing returns for operating at even higher temperatures. Impact of Temperature Fluctuations The study also examined the effect of daily temperature fluctuations on the AD process. Both upward and downward fluctuations of 10°C were introduced for specific periods. The findings suggest that upward fluctuations have a more detrimental impact on methane production compared to downward fluctuations. Implications for Biogas Production These findings offer valuable insights for optimizing biogas production from cow manure: Maintaining a stable temperature: While thermophilic AD offers advantages, precise temperature control is crucial for maximizing efficiency. Potential of solar energy: The study highlights the possibility of utilizing solar energy for daytime reactor heating, eliminating the need for constant temperature maintenance. However, further research is needed to ensure this approach doesn't lead to overheating or instability. Looking Ahead This study paves the way for further development of sustainable biogas production from cow manure. By optimizing temperature control and potentially integrating renewable energy sources like solar, AD can become a more efficient and environmentally friendly approach to waste management and clean energy generation. #BiogasProduction #WasteManagement #RenewableEnergy #SustainableSolutions #HighPHWaste #MethaneOptimization #CircularEconomy #EnvironmentalTech #GreenInnovation #ResourceRecovery Reference: [1] Effect of temperature and temperature fluctuation on thermophilic anaerobic digestion of cattle manure [DOI: 10.1016/j.biortech.2003.07.013]

This collaboration with GuarantCo not only enhances our credibility but also unlocks financing for IPPs developing renewable energy projects in the region. A huge congratulations goes to our Chief Investment Officer Pug Bennet and Chief Commercial Officer Cathy Oxby for this incredible milestone in our growth. This announcement holds particular importance as it comes during the 56th Executive Meetings of the Southern African Power Pool in Lusaka, Zambia, hosted by Zambia Electricity Supply Corporation (ZESCO) and ZESCO MD Eng. Vic. Ben. Mapani. GreenCo was a proud sponsor of the event as the first Market Participant member of the Southern African Power Pool. Reflecting on this emotional juncture, I can't help but recall the collaborative genesis of GreenCo's business model. From its conceptual infancy during the 2016 SAPP meetings in Angola, where I, alongside Africa GreenCo's co-founder Lovemore Chilimanzi, presented our vision, to this groundbreaking moment back amongst the Southern African Power Pool family, the journey has been profoundly inspiring. It's truly heartening to see the support and encouragement from SAPP and all its members and in particular our host utility Zesco Limited without whose support we would not be here today - and regulators that have contributed to our progress and facilitated our expansion of the model to South Africa, Zimbabwe and Namibia. The words of Hon Minister of Energy, Hon. Eng. Peter Kapala, MP, resonated deeply to me, underscoring the transformative potential of interconnectedness within the SADC region and his Excellency's Hakainde Hichilema leadership. Zambia Electricity Supply Corporation (ZESCO) MD’s Eng. Vic. Ben. Mapani poignant acknowledgment of the region's power challenges - including the current impact of climate change on Zambia's hydro availability - and acknowledgement of the role of the SAPP as a platform where common challenges can be confronted together, coupled with Board Chair's Vickson Ncube reminder of the regions historical legacy further galvanizes our commitment to deliver in collaboration with regional utilities. Furthermore, SAPP Executive Secretary’s Steve Dihwa emphasis on SAPP's interconnection with EAPP and the recent launch of the RTIFF as a new transmission investment facility brought to light positive developments.

As a unique combination of a History major and a biogas nerd, I find immense fascination in embarking on the journey through the annals of time to discover the rich history of #biogas! 🤓💨🌿 🔥Biogas, with its ability to provide heating, cooking, and lighting, has been a silent hero in low-tech environments for centuries. Its first use dates back to the 10th century in Assyria as a source for heating bathtubs. The genesis of modern biogas facilities dates back to 1859, with the construction of the first biogas digester at a leper colony in Bombay, India. 🦠🔬Fast forward to the 1930s, advancements in microbiology led to an explosion of discoveries in anaerobic digestion technology. The pioneering scientists Buswell and Hatfield uncovered anaerobic bacteria and the conditions needed to promote optimal methane production. This paved the way for modern biogas facilities to make their mark. 📈 According to the World Biogas Association, as of 2019, over “132,000 small, medium or large-scale digesters are operating in the world. “ The numbers continue to grow rapidly each year. Current trends point towards biogas production nearly doubling by 2040. 🚧 The journey of biogas hasn't been without its challenges. Technological advancements have undoubtedly enhanced the collection and utilization of biogas, but they've also introduced complexities and additional costs associated with the management process. A severe lack of global education and awareness of the technology proves as a consistent and crippling roadblock as well. 💡Biogas has roots stretching back centuries, proving that sustainability isn't just a modern buzzword—a timeless endeavor embedded in our history. Anaerobic digestion has quietly ignited communities, offering a sustainable solution to waste management long before it became a global priority. It's not new news; it's an ancient practice that has stood the test of time. ⚡So, let's cut the crap with biogas technology. It's time to harness the potential of AD and hop on board for a future fueled by waste. Embracing this proven technology promises to reduce our dependence on fossil fuels, mitigate greenhouse gas emissions, and pave the way toward a bright tomorrow. 👋 Please share this and comment so we can spread the celebration of the rich tapestry of biogas history and the ongoing quest for sustainability through innovation. #RNG #renewableenergy #renewablenaturalgas #biomethane #biofuels #bioenergy #wastetoenergy #sustainableenergy #anaerobicdigestion #circulareconomy
