Regenerate urban waste
& Boost Urban Agriculture
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
Keep the biochar
Greenhouses need higher CO2 levels than ambiant air
...and heat
800-1000 PPM
430 PPM
CO2 levels vary as plants take up carbon
Excess and depletion should be balanced
We will use DACC to do
only the buffering work,
clipping high levels of CO2
and sustaining low levels of CO2.
While filter the flue gas
to use only CO2.
600-1000 PPM

IN:
Clean wood waste
Recycled / Looped:
Heat + CO2
OUT:
Produce
Biochar
Trees
This way we get a
80% Nature based
20% Technology based
solution
To provide
a more permanent carbon storage
we should also grow:
-
Trees for afforestation
-
Fast rotation plants for biomass burial
Best LCA possible

Our goals:

A site to locate a demonstrator ?
Where Paris had an history with Carbon
or any site related to the Carbon Legacy...
The abandoned railroad track
to "Gare des Mines"
(Coal Mine Station)
north of Paris
...The place where coal and gas were brought to Paris during 100 year.
