Production line and factory setup overview
A micro/small controlled-pyrolysis line converting one clean Afghan crop or wood residue into soil-grade biochar through feedstock identification, contaminant removal, size control and drying, oxygen-limited batch retort or small continuous carbonization, syngas afterburn and flue-gas treatment, sealed oxygen-free cooling, optional crushing and screening, safe conditioning, laboratory characterization and dust-controlled packing. It is distinct from activated carbon and fuel-briquette production.
Recommended lowest-entry line configuration Start with one naturally dry pruning or clean wood-residue feed and a sealed batch retort or 200-300 kg/h continuous reactor only if the supplier includes controlled feeding, gas-tight discharge, afterburner, particulate treatment, temperature logging and sealed cooling. Sell only after independent soil and contaminant tests; do not claim activated-carbon adsorption performance.
Production process and implementation sequence
- Feedstock identity and contaminant release
- Sizing and moisture control
- Metered oxygen-limited pyrolysis
- Syngas afterburn and flue-gas treatment
- Sealed oxygen-free cooling
- Crushing, screening and conditioning
- Biochar laboratory release
- Dust-controlled bagging and traceability
Products, capacity and market fit
- Orchard prunings and clean crop residues can become a stable soil-carbon product.
- A controlled retort prevents the smoke and fire risks of open pits.
- One feedstock produces more consistent carbon and ash results.
- Environmental approval, PAH testing and local soil trials are essential.
- Soil-grade biochar - Feedstock, production temperature, particle size, moisture, ash, fixed carbon, pH, EC, stability, metals and PAH limits - Soil amendment and compost blending only after local agronomic trials
