Start with your biomass; it's the one number the tool can't estimate for you. Everything below is prefilled with sensible defaults, ready to edit if you know it.
Upload a soil test as PDF (Spanish lab format with pH, CICe, P, Sat. Acidez), CSV, or JSON. Multi-lot PDFs are averaged.
Optional inputs
Prefilled defaults. Edit these if you know your numbers.
Advanced settings
Technical and financial assumptions. Most users can leave these as they are.

What you’d be installing
Equipment is described by category and scale, not by brand. There are good options at every level. Once we know your country, your feedstock, and how much residue you have, we propose the specific units that fit.
On-farm, single farmer
Low capitalA small-scale, low-cost on-farm kiln is the simplest way to start. A flame-front design oxidizes gases released in the combustion process, controlling emissions. Suitable for a single farm running a few batches per season.
Single farm or small co-op
Mid-range capitalA batch reactor with built-in emissions controls is towable, so a single unit can either serve one farm year-round or rotate among member farms in a small co-operative. A standard mid-tier choice.
Wet mill or processing center
Higher capitalA continuously fed system designed for processing centers with year-round residue offers higher throughput and more automation than the batch options. The right fit when one location aggregates enough biomass to keep it running.
Capital and operating costs vary widely by country, by labor rate, and by import duties on equipment. We quote the real numbers once we know the project context.
