More widely, in countryside as in cities, human activities ultimately result in waste, emissions and other elements as outputs depending on the specific inputs of these human actions. Then here we can state: wastewater treatment technologies, green architecture technologies, zero-emission transportation (biofuel as bioethanol greatly popularized today with Elon Musk’s recent rockets for example, biodiesel, etc), sustainable public facilities, etc. In Annual Review of Energy, page 47 and more at 47–80 of Mills GA and Ecklund EE (1987) titled “Alcohols as Components of Transportation Fuels”, it is said: “Alcohols have the potential to revolutionize energy fuel supply and use, particularly in transportation. This worldwide potential is based on (a) the variety of widely available raw materials from which alcohols can be made (coal, natural gas, petroleum and biomass), (b) the improved and demonstrated technology for alcohol manufacture and use, and (c) the favorable combustion characteristics of alcohols, namely clean burning with high octane performance. Therefore, the motivated UNEP Tunza Eco Generation’s Ambassador that I am, can easily deduce that as alcohol, there is surely other good sources that can allow humanity many eco-friendly technologies, more than what we have actually and precisely, more for real practice that we’re actually forcing ourselves to have (and funny, because now the consequences of our harmful actions are before our eyes).

Moreover, some field visits made in my country allowed us to see that we have actors like Burn pits (Pyrolysis), Biodrying installations, Composting (In-vessel, Windrow and Tunnel types), Pollution control services, Sewage regulation and administration, rare civic amenity site (CA site) and others waste management companies as a friend mine startup in transforming plastics to filament for 3D printing. Notable in the country's history, a first 65 MW power plant was launched on April 26, 2021 called Kekeli Efficient Power (initially, planned to generate 47 MW of power through the gas turbine, then a power of 65 MW at the end of 2021, with the addition of a steam turbine). Kekeli meaning light in a local language here. Let’s rementionned the use of electric motorcycles by citizens thanks to local transport companies such as M AUTO, PIKI PIKI etc as I have already mentioned in  [April 2023 Theme Report] Air Pollution by Richard Adayi | 23-04-2023 08:10. Clearly, we have noticed technologies specific to organic waste, Control regulations and technologies being imported and others through youth’s innovation mini-projects.

On a continental scale, this is the place to mention the Bamako convention on the ban on importing hazardous waste into Africa and on the control of transboundary movements and the management of hazardous waste produced in Africa by twelve nations of the Organisation of African Unity at Bamako, Mali in January, 1991, and came into force in 1998.

And from these visits, we end up being convinced that in countries that feel and are beginning to feel concerned about the climate issue as a whole more than this previous list is being done. For example: Established waste hierarchy and public dustbin installations for recycling and sort (Waste autoclave), Waste treatment rigorous legislations, National waste minimization politics, National waste studies institutes for national statistics and popularization to all from children to adults, Upflow anaerobic digester or UASB applied to solid wastes,  Gasification, Plasma gasification (Gasification assisted by plasma torches), Hydrothermal carbonization, Hydrothermal liquefaction, Mechanical biological treatment (sorting into selected fractions).

To sum it all, as Mentor James previously said to me, this topic is selected for May because of the diverse backgrounds of us Eco-generation ambassadors, and thought it would be great to acknowledge all the variegated, developing urban technologies within our representative regions. My fellow readers and Ambassadors, I have presented to you the list of what is currently done here at the beginning of my third paragraph and also dears, allow me to say that around me, in 2023 people still throw away without much scruple and conscience, their pure water sachet in the street after drinking the content because here it is still ordinary, yes. And yes, I’m also probably 30^th Eco Generation Ambassador to try to solve that!

Thank you.
