It is in this context that production of renewable energy such as biofuel has gained a lot of interest in recent years. Despite the increasing interest, the major limitation associated with this technology is the high cost of producing renewable energy compared to that of the fossil fuel. To address this problem, there are two approaches that define the trajectory of the research path that adds value to life. The first one is the use of wastes or low-cost materials as feedstock for energy production. This approach is often described as waste beneficiation. In recent years, the efficiency of many processes has been enhanced by the use of nano-modified materials. The second approach involves the integration of the conventional energy production processes with advanced ones to improve production. The performance of the integrated system can be improved by optimizing the operating conditions, and this can be done by using experimental and simulation techniques.
Experimental methods are more costly than the simulation ones. For multiphase systems such as heterogeneous photodegradation and anaerobic digestion, computational fluid dynamic technique (CFD) can be employed to optimize the process and reduce the operational cost. In this regard, solar photodegradation has been successfully integrated with anaerobic digestion to reduce the cost of producing bioenergy from waste. The wastes resulting from such processes can be used as fertilizer to improve food production. This is the water-energy-food nexus, which can improve energy production with a trickle-down effect of waste beneficiation in food production. At the Centre For Renewable Energy And Water, we look at this kind of research approach, and the cutting-edge technologies that are employed to address the most pertinent community problems and hence improve the quality of life.
