The gains from implementing BIA can improve the efficiency of the entire city when seen as a whole.
And that is what Urban Metabolism does: it studies the whole of the city as an ecosystem full of independent organisms, and builds new connections between them, so the waste from one becomes the food for the next
This is a simplified example of a Closed loop found in nature:
If we find the flows of resources like water, energy or materials in the cities, we can connect them, so we stop just letting heat disappear into the universe, dirty water go to the ocean, or food waste go to landfills.
Another example of this can be our project for mushrooms:
- Local Coffee shops give us their used coffee grounds (when you make a coffee you only use 20% of the grounds on it)
- We take them on our bicycle to our local farm, where we mix them with mycelium
- Fungi will start spreading, and in 1-6 months edible MUSHROOMS will sprout
- Again by bicycle, these mushrooms get delivered to local people, supermarkets and restaurants
A London with plenty of farms on it would:
Reduce its carbon footprint as a whole:
Less food would need to be imported, so less traffic on its roads and less nasty gasses
Plants in the farms would absorb CO2, making for low carbon buildings and a healthier city
Energy efficient buildings
Reduced Heat Island Effect, and its related effects on human health
create fertilizer for food out of food waste
