Toggle the feedstocks you want to include in the production blend. The library now spans the full top row so material choice happens before blend and supply planning.
Multi-feedstock pyrolysis calculator — 5-year projection with material life assessment
Start with the material base. This stage fills the page with three planning cards so the feedstock library, allocation mix, and supply depth can be reviewed side by side.
Toggle the feedstocks you want to include in the production blend. The library now spans the full top row so material choice happens before blend and supply planning.
Allocate the selected feedstocks until the blend totals 100%.
Set monthly availability and total supply duration to test how long the feedstock base can sustain the project.
Move directly from feedstock choice into kiln design. Orientation, moisture effect, and operating setup are split into clear planning boxes across the page.
Stay on auto for a feedstock-led recommendation or switch to manual selection.
Wet feedstock lowers effective yield and can reduce carbonisation performance.
Choose the physical kiln size, active kiln count, and daily operating cadence.
This section keeps the commercial output logic full-width. Pure biochar, value-added products, and compost blends are now organised as three side-by-side decision panels.
Define how much monthly biochar remains pure and how much flows into compost-based products.
Set the allocation and selling price for each pure-biochar product line.
Price the biochar-compost product family and track its share of total output.
Operating costs, CAPEX, and assumptions are broken into three large working boxes so the economics can be edited without scrolling between unrelated inputs.
Enter the monthly base cost stack. Variable items scale with active kilns.

Adjust return thresholds, pricing growth, inflation, and operating months for the 5-year model.
The operating outcome now has its own dedicated band. Core financial metrics sit first, followed by the supporting margin and throughput indicators.
Close with project viability. The feedstock life test sits alongside the projection tables so supply resilience and the financial model can be assessed together.
