[PROJECT] Biomass

[LesUsines_Louise]

Continuing the discussion from Bio-inspired scale and methods to rethink energy production
and Challenge: Better use of biomass for energy production

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.

Aim
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.

Concept

Questions

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?

Answers
the OSCE community proposed some answers

It depends on the green waste and things like water content. For a biogas reactor digesting poop the power is something like 6.9 kWh per litre of biowaste Just copy pasted from some spreadsheets we had on modelling biogas production for a population of 50k maybe… Biogas production 110,348.44 kg/day [5] 220,696.88 l/day 6.90 kWh/l biogas 1,522,808.50 kWh/day 1,522.81 MWh/day 63.45 MW power production 9.69 kWh/person/day other research [6] 0.5 m3/kg TS 55174.2 m3/day biogas produci…

@cameralibre @TeamVarambon I think the fair response is “that depends”… since biowaste is not homogenous and there are different types of biowaste a kg of it will always have a different energy value. Therefor it is really crucial for you to be aware of which types of biowaste you are talking about. Here may be a good link which may be able to serve as orientation for your challenge. It gives an overview into different types of biowaste and their energy values: http://teeic.indianaffairs.gov/e…

@Sharon Prendeville: you could try the waste resources action programme (WRAP) for this type of data. … http://www.wrap.org.uk/

Next steps
Information has to be compiled, also similar projects will be studied. We are waiting for published results of OSCEdays team working on energy challenges

[CHALLENGES] Bio-Based Materials, Energy and Water in the Circular Economy

We will explore the emerging bio-based economy and walk through some of the best raw material inputs for industrial scale change. From hemp to mushrooms, nature provides the sustainable solutions industry is looking for. We will also discuss the use and re-use of energy and water in industry-farming symbiotic networks.
