dear friends at e4c greetings and thanks for circulating the important information regarding the off-shelf and tested technology : the waste into green energy (renewable energy)
is there a way for transfer of these already tested and off-the shelf technologies into full commercialization and full adaption in Africa ?
i shall appreciate hearing from you.

Very interesting and widening the thinking of the researchers and developers.
Please note that burning biomass in energy from wastes (EfW equipment/plants) also wastes potential excellent fertiliser (of great benefit in developing countries!) instead of using as feedstock for anaerobic digestion (AD). AD ought always to be examined first!
Furthermore, consideration should be given in the use of biogas for energy generation (or other relevant motive power) to alternative use in a stirling engine chp unit (with some gas clean-up) instead of steam/CHP.
Hi Henry. The technologies in this article are in varying stages of development and have service components and maintenance requirements that limit them from being “off the shelf”. But full commercialization from the origins of the technology development to target markets require modification for end user preference and business model adjustments and service expectations to account for region specific customs. Given you are in Rwanda, I wonder if you could shine some insight into what are some important factors to consider when implementing biodigesters in Mexico vs. East Africa, or utilizing human waste streams for a fuel source, or combusting agricultural biomass residues. I encourage you to post your insights here.
Brian, thanks for the insight. Biogas has the highest efficiency when used in domestic cooking and is most widely used in this setting to displace LPG or biomass use. Combustion in a modified generator works well for larger AD systems and is a great way to generate mechanical and electrical Power.

friends of the above topic
thank u 4 contributing the idea. still we are under privileged to get through the best method to utilize bio energy. we need further co ordination and help to produce electricity out of waste (urban). so we need further details.
I like engineering for change
