Substitute fuels

Use of alternative fuels is rapidly growing with a trend towards pushing for better and more efficient use of this “Refuse-derived” resource. These secondary fuel sources, comprised of many different types of material commonly found in household and industrial waste, are burnt to produce heat in processes such as cement, lime and brown coal production, or for generating power in Refuse Derived Fuel (RDF) power plants.


The value of RDFs is derived from the calorific content – which is determined by material type and is therefore not affected by colour or shape. A precise value can only be estimated correctly with accurate material recognition.


EVK with their HELIOS camera technology combines decades of experience in solving material recognition problems using a combination of flexibility – in user software, and adaptability – in camera hardware. EVK offers complete sensor solution concepts to be implemented, and eventually be patented, by our customers.

Near Infrared Hyperspectral Imaging offers the degree of classification accuracy necessary for such applications, by directly measuring the chemical molecular composition through the absorption of light (spectroscopy). 

EVK’s portfolio of sensor-based sorting technology includes Colour, Hyperspectral and Inductive sensor systems, which can be used individually or, with Sensor- Fusion, can be combined to form a powerful sorting application that can process multiple material types.
