Compare gasification, pyrolysis and additional products.
Thermochemical routes use heat and controlled conditions to convert material into process gases, liquids or solids. Each route requires its own input specification, process controls and product markets.

Assess the full balance
Include drying, preparation, process energy, contaminants, rejects and emissions control. Raw gasification gas is not ready for natural-gas network use without the required downstream treatment.
Qualify each output
Useful heat, liquids and char have different acceptance requirements. Assess the additional processing and customer value separately. Biochar and hydrochar require distinct product and carbon-storage evidence.
Gasification, pyrolysis and their products
Gasification converts dry biomass into a combustible gas that can produce heat, power or, after cleaning, chemical feedstocks. Pyrolysis heats material without oxygen to produce bio-oil, gas and biochar in proportions that depend on temperature and residence time. Tar management, feedstock consistency and product cleaning are recurring engineering challenges. Treat performance figures from small trials cautiously until a unit has run on comparable feedstock for an extended period.
Keep each output on its own evidence line
Gas, liquid and solid products from thermal conversion need separate mass balances, quality specifications and customer pathways. Confirm feed preparation, moisture tolerance, emissions controls, residue handling and process-energy demand with the equipment provider. Do not count syngas, heat, bio-oil and biochar as simultaneous saleable revenue unless the selected configuration can produce each output at the stated quality and customers have been identified.
Frequently asked questions
Can digestate become biochar?
Additional conversion may be assessed, but moisture, preparation, energy and product quality can materially affect the result.
What is the difference between gasification and pyrolysis?
Gasification uses limited oxygen at high temperature to produce a combustible gas. Pyrolysis heats material without oxygen to produce oil, gas and char in proportions set by process conditions. Each needs a specific feedstock and has its own product markets.
Are thermochemical routes commercially proven?
Maturity varies widely by technology, scale and feedstock. Ask for operating references with comparable material, operating hours and product quality, and treat pilot or demonstration results as evidence that still needs commercial validation.
