A Grade RCF
A Grade is the highest quality of waste wood. This ‘clean’ low moisture material consists of waste, cuttings and shavings from solid wood in its natural state, packing cases and pallets made from solid wood, and cable reels with nails and other metal removed during the process. The high quality of A Grade biomass means it is suitable for use by facilities that have not been specially licensed under the Industrial Emissions Directive.
B Grade RCF
B Grade RCF is a low moisture fuel made up of waste wood from the construction and demolition sectors. As a result, material contains wood with paint or other treatments. The shredding and recycling process separates out the non-wood materials, such as metals and other inerts.
C Grade RCF
C Grade recycled fuel is typically made up of waste reclaimed from kitchen refurbishments,
discarded furniture and other fixtures and fittings. It can include chip board and MDF as well as solid wood and will contain wood with coatings, varnishes and glues. Processing during shredding separates out non-wood articles, such as metals and other inerts.
The shredding process inevitably produces fine material unsuitable for normal heat and power generation. These ‘fines’ are collected during the screening process and can be blended with other Industrial Emissions Directive approved fuels, or delivered direct.
RDF stands for Refuse-Derived Fuel. Higher grades prepared to meet stringent standards are often known as ‘solid recovered fuel’ or “SRF’. These particularly environmentally positive biofuels consist largely of combustible components from waste, such as plastics and biodegradable waste which is shredded to a standard size and then dehydrated to make a useful low carbon energy source, often called ‘flock’.
Solid Recovered Fuel, or SRF is high grade RDF that has been sorted and processed to meet CEN/343 ANAS standards. Like RDF, this is a highly environmentally responsible fuel that plays a key role in reducing reliance on expensive landfill as well as cutting carbon emissions during energy production.
