Solid Fuels



We are specialists in the sampling and analysis of RDF, SRF and MSW such as waste wood, solid non-hazardous industrial and household waste or any material that fits the requirements of standard BS EN 15359.

We know that the smallest discrepancy in results can make a huge difference to our clients’ operations. We keep an open conversation with our clients during our services, promptly advising of any non-conformities.


  • Solid Recovered Fuels
  • Refuse Derived Fuels
  • Municipal Solid Waste
  • Commercial & Industrial Waste


With a number of strategically placed UK hubs, we can provide chemical analysis and independent testing to determine the quality of your fuel and the efficiency of your screening and plant operations, bringing together a full range of analytical services.

Our services provide our clients with clarification of which materials are present for a screened waste, indication of the presence of hazardous contaminants in materials and reliable waste profile and accurate data, enabling informed views to be made on the performance of waste treatment facilities.
