Thermal Waste Processing Complex (Pyrolysis / Gasification)

Thermal Waste Processing Complex (Pyrolysis / Gasification)

1. Electric Pyrolysis ETIA (Biogreen Technology, France)

The technology is based on the patented Spirajoule process, where feedstock heating takes place inside a sealed screw conveyor by passing electric current directly through the metal screw (Joule effect).

Feedstock

 • Biomass (wood chips, straw, husks)

 • Sewage sludge

 • Medical waste

 • Selected types of plastics

Output

 • Biochar

 • Pyrolysis oil

Processing Capacity

Modular units with throughput ranging from 100 kg/hour to 4,000 kg/hour of input material.

Investment (CAPEX)

Approximately €1.5 million to €6 million per turnkey production line.

Payback Period

Estimated at 4–6 years, depending on electricity costs and market prices for the final products.

2. Classical Gasification (Waste Gas Processing)

This technology involves thermal destruction of feedstock at temperatures of 800–1200°C under limited oxygen conditions.

The primary product is syngas, which is used for heat and electricity generation.

Feedstock

 • Used tires (rubber)

 • Mixed plastics

 • Wood residues

 • Sorted municipal solid waste (RDF)

Processing Capacity

Industrial units designed for capacities from 1 ton/hour to 10+ tons/hour.

Investment

From $2 million to $12 million, depending on system configuration.

Payback Period

Estimated at 3–5 years, driven by gate fee savings and natural gas substitution or electricity sales.
