Eliminating expenses

Through drying and incinerating, millions of tons of waste which currently goes to landfill can be transformed into highly valuable Refuse Derived Fuel (RDF). Discover the reduced costs to your bottom line through drying waste and refuse with Stronga Waste Series.

  • Reduced transport costs. Dry waste has a lower weight by volume, meaning you can transport more on each truck, equating to fewer trucks required, fewer journeys made, less labour needed and less fossil fuel consumed.
  • Reduced processing costs. Improved waste fraction separation. Dry waste is easier for process machinery to handle, equating to higher output per hour, less labour required, lower fuel consumption and lower total machinery expenditure.
  • Reduced landfill costs. Avoid costs associated with waste disposal through landfill diversion, fulfilling your zero waste to landfill ambitions. Waste to energy can reduce landfill volume by up to 90% and prevent 1 tonne of CO² release for every tonne of waste combusted.
  • Reduced Energy from Waste (EfW) export costs. Save significant sums paid in export gates fees while profiting from waste to energy incentive schemes.

    Waste to energy schemes

    With many Government’s committed to reducing GHG emissions, waste to energy initiatives help establish renewable solutions in the market. Capital and tariff based schemes are available to help repay the initial system set up cost

    fuel icon FlowDrya WS

    Waste to energy schemes encourage the uptake of renewable heat technologies among local councils and businesses through the provision of financial incentives. Government’s pay an incentive or capital grant depending on the dryer type and size.

    Giving waste direction

    Enabling the next generation of alternative fuel.

    Injecting high quality drying air through the wet waste fraction as it flows along the PulseWave™ drying floor optimises the evaporative drying process to reduce moisture content to a desired level.

    The highly efficient PulseWave™ motion thoroughly mixes materials on the drying floor. PulseWave™ ensures that every part of the waste material interacts with hot bed metal during the flow and receives an equal airflow, leading to uniformity of dryness.

    Enabling alternative fuels

    Drying waste in preparation for use as an alternative fuel enables practical, economic and environmental benefits.

    • Reduction of imported fossil fuel costs.
    • Reduction of non-renewable fossil fuel usage, with associated environmental benefits.
    • Landfill diversion. Processing waste into SRF is cheap, sustainable and environmentally-friendly.
    • Reduction of NOx and CO₂ emissions using substitute fuels instead of lignite or coal.


    As well as enabling valuable alternative fuels, drying waste also improves the fraction separation process as machinery works more efficiently with drier, easier to handle fractions. Discover the fundamental benefits of drying waste with Stronga.


    Recycling higher %’s

    Waste fractions are highly variable, abrasive, sticky and non-free flowing.

    You need a dryer that is flexible enough to cope with non-homogenous materials. The FlowDrya WS combined with Stronga experience in the sector, enables materials of varying bulk densities to be efficiently handled in a robust and reliable way.

    The outcome is higher recycling rates for your business. Process and recover a lot more material from your waste streams today.
