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.

Feedstock, process, products and project considerations
TechnologySuitable feedstockConversion environmentMain outputsTypical project fitKey project conditions
PyrolysisSuitable 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.
GasificationPrepared 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 / biogasBiodegradable 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 incinerationAssessed 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 combustionSuitable 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.

01 / STAGED CONVERSION

Separate process functions

Primary decomposition and downstream gas-conditioning requirements are addressed through a two-stage route.

02 / USEFUL GAS

Match a real application

Gas quality and flow are evaluated against the industrial heat load and intended equipment.

03 / SOLID OUTPUT

Qualify the carbon fraction

A suitable solid-output route is developed alongside energy recovery, based on origin and test results.

04 / MODULAR APPROACH

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.
