IEA expectations:

My expectations for the new triennium of the Task 36 IEA-BioEnergy are those of continuing assisting the Dept. of Energy of South Africa and SANEDI in navigating the Just Energy and decarbonisation Transition of South Africa, through the localisation of appropriate technologies, knowledge transfer within the Task Group and more importantly learning from your respective experiences more about the institutional frameworks and drivers/barriers that have enabled the introduction of innovative waste-to-energy and nutrient-recovery solutions in your respective countries, that could develop in a comprehensive institutional framework and decision making tool for South Africa, with particular respect to bioenergy projects.
