BMH Enviro’s waste crusher produces RDF with 70% biomass content


Source: Beta Analytic Inc.

BMH Enviro’s Tyrannosaurus® heavy-duty crushers convert waste into refuse-derived fuel (RDF) that is 70% biomass according to CEN 15747, a method that can determine the renewable content of most materials. Using RDF with high biomass content helps companies lower their greenhouse gas (GHG) inventories and obtain more carbon credits in cap-and-trade programs.

Companies in energy-intensive industries use RDF for many reasons. Some use RDF as fossil fuel substitute or co-fire it with coal to decrease fuel spending. Cement plants in Europe, for example, use RDF to comply with the strict standards of the EU Waste Incineration Directive. In regions with carbon emissions cap-and-trade systems in place, companies incinerate RDF to keep their GHG emissions within established limits and obtain carbon credits that they can sell or trade.

Most refuse-derived fuels are from municipal solid wastes - a mixture of biomass (e.g. paper and wood) and fossil-based materials like plastics. The biomass portion of RDF when burned produces carbon-neutral CO2 that is exempted from regulatory reporting and deductible from GHG inventories. The higher the biomass content of the RDF used, the more credits a company can potentially obtain.

Tyrannosaurus® - the Giant Among Waste Crushers
BMH Enviro’s waste-to-fuel process provides a different approach to waste treatment and recycling. The heart of the system is the Tyrannosaurus®, which is designed for industrial-scale, continuous waste crushing. It can make products of different particle sizes in a single pass using common wastes or even tough materials like used car tires. BMH Enviro’s system usually includes other products with different capabilities like machines that separate ferrous from non-ferrous metals, screening devices, waste feeding systems, and conveyors, among others.

CEN 15747 Testing

The RDF produced by BMH Enviro’s Tyrannosaurus® Waste Crusher was tested for renewable content in Beta Analytic’s lab in Miami, Florida. Results showed that the RDF sample is 70% biomass. A copy of the report is found here:

CEN 15747 was developed specifically for Solid Recovered Fuels testing. The method is the European equivalent of ASTM D6866, a standard that originated in the U.S. and used to determine biomass content of solids (like RDF and bioplastics), liquids like biofuels, and gases like emissions from combustion stacks.
