Separate process functions
Primary decomposition and downstream gas-conditioning requirements are addressed through a two-stage route.
Circular Energies · Technology comparison
The right technology starts
with the right waste stream.
Compare ECircular pyrogasification with pyrolysis, gasification, anaerobic digestion, waste incineration and direct biomass combustion. Feedstock, outputs and integration needs determine the appropriate route.

What value do you need?
This qualitative selector offers an initial engineering interpretation of the technology options. Feedstock testing and a site review establish the project-specific decision.
Indicative engineering fit
Assess ECircular alongside gasification and combustion
Prepared dry biomass can supply industrial energy through several routes. Compare delivered heat cost, feedstock quality, integration and operating needs.
Six conversion routes
A practical comparison.
Each process has a useful place. The matrix compares general operating principles and project conditions; it does not assign untested efficiency, cost or emissions rankings.
| Technology | Suitable feedstock | Conversion environment | Main outputs | Typical project fit | Key project conditions |
|---|---|---|---|---|---|
| ECircular pyrogasification | Prepared biomass and assessed residual fractions; selected plastics subject to compatibility review. | Primary thermal decomposition followed by secondary gas conversion and conditioning. | Fuel gas and a separately managed solid carbon fraction. | Modular industrial-energy projects with a defined gas and material outlet. | Preparation, tar and contaminant management, burner matching, residue testing and site validation. |
| Pyrolysis | Suitable biomass or selected prepared polymers. | Thermal decomposition without oxygen. | Gas, condensable liquids and char; their proportions depend on conditions. | Projects focused on qualified char or liquid recovery, with energy use of gas where viable. | Product specification, condensate handling, energy balance and feedstock consistency. |
| Gasification | Prepared carbonaceous feeds compatible with the chosen gasifier. | Heat with controlled air, oxygen and/or steam. | Syngas and solid residue, depending on reactor and feedstock. | Heat, power or downstream conversion with a matched gas-quality requirement. | Gasifier selection, gas cleaning, contaminants, ash behaviour and downstream compatibility. |
| Anaerobic digestion / biogas | Biodegradable organic matter, including food waste and manure. | Microbial conversion in the absence of oxygen. | Biogas and digestate. | Wet organic streams with a biological treatment and energy-recovery pathway. | Biological stability, gas treatment and a suitable digestate-management route. |
| Waste incineration | Assessed residual municipal or industrial waste. | Controlled combustion with excess air. | Recovered heat or steam, electricity where configured, and ash. | Residual-waste treatment linked to an appropriate heat or power system. | Air-pollution controls, ash management and the applicable facility approval process. |
| Direct biomass combustion | Suitable prepared solid biomass fuel. | Fuel burned with sufficient combustion air. | Heat or steam; power where equipped; ash. | Heat-led applications with a reliable biomass-fuel supply. | Fuel quality, boiler or burner suitability, emissions controls and ash handling. |

Waste incineration is a form of combustion. It is listed separately here to distinguish mixed residual-waste treatment from direct use of a prepared biomass fuel.
Where ECircular is positioned
An integrated route
for industrial energy users.
The value proposition lies in the selected feedstock, staged process and local energy integration. Its benefits are established through the engineered project.
Match a real application
Gas quality and flow are evaluated against the industrial heat load and intended equipment.
Qualify the carbon fraction
A suitable solid-output route is developed alongside energy recovery, based on origin and test results.
Develop around the site
Capacity and configuration follow the available feedstock, customer demand and operating plan.
Before selecting a route
Compare the complete project economics.
Delivered energy cost
Include feedstock collection and preparation, parasitic energy, labour, maintenance, gas cleanup and the useful heat actually delivered.
Outputs and obligations
Confirm credible buyers or uses for recovered products. Include residue handling, monitoring and environmental operating requirements.
Operating fit
Check daily material consistency, heat-load variation, operator skills, backup fuel, spare parts and expected downtime.
