Certified High-Calorific Pellets
The energy of the future is waste-derived fuel
Solid recovered fuels are produced primarily from non-recyclable, high-calorific fractions of industrial and municipal waste. Their energy content is more than double that of coal and biomass typically used in Czech district-heating plants.
Calorific Value
Biogenic-content pellets are becoming increasingly important for industry as a means of reducing emissions associated with fossil fuels. They can be used as a full-value substitute for coal or as a stabilising component in biomass boiler fuel blends, improving combustion stability and mitigating common biomass drawbacks such as low calorific value, self-heating risk, high moisture content, and ice build-up.
What are high-calorific pellets?
Stable Energy Source
High-calorific, waste-derived pellets provide a stable fuel source for the heating season. Their quality shows no material seasonal variability and moisture content remains largely consistent.
District-heating and power can combust these pellets to generate heat and/or electricity in line with current demand.
Owing to their stability, production can run year-round, with inventory buffered in silos during periods of lower heat consumption.
Under Decree No. 169/2023 Coll., which defines when waste-derived solid fuel attains end-of-waste status, solid alternative fuels may be combusted only in stationary combustion sources with a total rated thermal input exceeding 20 MW.
We innovate waste management for a sustainable world
Pellets are produced on two pellet presses with vertically oriented mills, each with a capacity of 3 t/h, with provision for a third press. Additional drying occurs during pelletisation and subsequent cooling with ambient air. Fines are removed from the finished pellets using a vibrating screen.
Pelletising
Pre-sorted waste is size-reduced to a 35 mm fraction using a single-shaft shredder. Downstream of the shredder, the material passes through ferrous and non-ferrous metal separation, followed by heavy-fraction separation. The processed material is then temporarily stored in dosing hoppers.
