Preparation and quality assurance of secondary fuels

For energy recovery, waste/waste streams require prior processing. The production steps for the manufacture of secondary fuels depend on the input materials. If rather single-variety production-specific waste is used, prior processing is less complex than for waste mixtures (e.g. high-calorific fractions of municipal and commercial waste or sorting residues).

Mechanical technologies (crushing, screening, sorting) are used as well as optical sorting techniques (near-infrared) to prepare secondary fuel of consistent quality. For co-incineration, the fuels are subjected to regular quality assurance; one possibility of independent proof of quality is the RAL Quality Mark 724 - Secondary Fuels.

Requirements for use:

Specifications of the secondary fuel recyclers

Requirements for harmless and environmentally friendly recovery
process-specific requirements

Assurance and verification of a consistently high quality of the secondary fuels

Quality assurance through regular analysis
Proof of quality possible through the RAL quality mark 724
Quality-assured secondary fuels can be labelled with the SBS® trademark.

Best practices/applications/signals:

Quality Association for Secondary Fuels and Recycled Wood e. V. (BGS), Corrensstraße 25, 48149 Münster, Germany

The aim of the BGS e. V. is to promote the production and use of quality-assured secondary fuels in order to conserve natural resources and reduce_{CO2 emissions}.

Quality-assured companies

Processors can have their secondary fuels certified according to RAL-GZ 724 if they meet its requirements on a regular basis.
