Boost Urban Agriculture
& Regenerate urban waste
in a close loop of carbon
Urban
Carbon
Biochar has proven
to be a solid CDR method...
Heated greenhouses are useful for food resilience...
but still emits CO2 during pyrolysis
but often rely on fossile heat sources
Lets make heat & CO2 from pyrolysis work for our greenhouse...
...and get rid
of the fossil fuels
Greenhouses need higher CO2 levels than ambiant air
...and heat
1200-1300 PPM
450 PPM
CO2 levels vary as plants take carbon
Excess and depletion should be balanced
600-1300 PPM
450 PPM
300 PPM
Why not let DACC do
only the buffering work,
clipping high levels of CO2
and sustaining low levels of CO2 ?
And filter flue gas to allow
only clean CO2 left
IN:
Clean wood waste
Recycled / Looped:
Heat + CO2
OUT:
Produce
Biochar
Trees
This way we will have a
80% Nature based
20% Technology based
solution
To provide
mostly permanent storage
we should grow:
Trees for afforestation
Fast rotation plants for biomass burial
Produce
Best LCA possible
Local co benefits
CDR

A site to locate a demonstrator ?
Where Paris has an history with Carbon...
Former "Gare des Mines"
(Coal Mine Station)
north of the 'Chapelle Charbon' quarter...
...The place where coal and gas were brought to Paris during 120 year.
