National capacity plan
Process capacity to add
This plan adds no new process capacity: it routes the national supply through the pools that already exist.
Solved material routing
Material → first destination
Swipe sideways to see the whole diagram.
MaterialsNational first destinations
Each material stream splits between the national process pools that treat it and, in red, the tonnage sent straight to final landfill. What a pool leaves behind is not a first destination: it is drawn in the outcome comparison below.
Current system vs your plan
Where each tonne ends up
Swipe sideways to compare both halves.
Current processesCurrent outcomes
Plan processes
Both halves carry the same final-year national tonnage: every pool's throughput splits into recovered, released and landfilled mass, and waste that never reaches a pool goes to direct disposal. The middle bridge shows the net change between the two outcome splits; it does not trace individual tonnes from one plan to the other.

Your choice and alternatives
Selected
Alternatives from the epsilon sweep
Every alternative solves the same decision question under the same bounds, with one further outcome pushed 10% harder. Figures are horizon totals; the signed changes compare each alternative with your choice.
The sweep found no distinct plan near this one that is not worse on every outcome.
