Proposed by Dr. Jérôme Payet, CEO and Florent Querini, LCA engineer @ CYCLECO: How could we use the energy that is embed in green waste to produce electricity BEFORE using their nutriment values for soil regeneration ?
Tons of annual green waste are generated by pruning hedges and trees along the roads plus other landscaping activities. They are generally either left on the soil to decompose after shredding, or brought to a field for composting
All this shredded wood has energy built into it, wasted through the decomposition
Nutriment are still there after burning
Electricity from biomass is usually produced from large-scale power plants, burning trees that could be used for construction, while waste from landscaping activities contain energy that is lost during decomposition.
The challenge here is to propose a way of producing electricity from these waste at a very small scale (1 m3 of biomass).
Electricity is already produced by nature at the microscopic small scale of cells, which generate a small electric current thanks to ion exchanges through the cellular membrane. Taking inspiration from this could help designing a breakthrough technology for small scale electricity generation.
Produce energy or heat with the power of green waste before it becomes compost in order to make it possible for an individual to heat part of his house. video presentation
The questions mostly concern the datas and the logistics
How much green waste is necessary to heat a house, where to put the container (it has to be inside in order to be effective) how big does it have to be, how can it be cleaned… How much potential energy is stored per kg or cubic meter of green waste?
the OSCE community proposed some answers
@Sharon Prendeville: you could try the waste resources action programme (WRAP) for this type of data. … http://www.wrap.org.uk/
Information has to be compiled, also similar projects will be studied. We are waiting for published results of OSCEdays team working on energy challenges
