The fibres in paper and cardboard can get recycled approximately five times, depending on the type of paper which is being produced. The fibres are discarded in the pulping process and end up in a sludge we call paper sludge. This paper sludge is a valuable resource for many industries, both as an alternative fuel as well as an alternative raw material. Paper sludge is used as an alternative raw material by ceramic industries, but it is also used in various other applications.Read more >
Stonewool granulate is shredded basalt substrate. Substrate slabs are being used in greenhouse cultivation to grow e.g. tomatoes . Substrate slabs last for about one year and after that these are collected. After collection the slabs are treated: organic pollutants and foils are getting removed and the slabs is shredded to what we call stonewool granulate. The ceramic industry uses stonewool granulate as an alternative material.Read more >
Paper rejects is the coarse residue coming from the pulping process. Next to fibres there is a significant amount of (non-recyclable) plastics in the material. Due to this fact, this material is very well suited to be used as an alternative fuel in waste to energy boilers, but it can also be treated further to be upgrade to an alternative fuel such as SRF.Read more >

The fibres are discarded in the pulping process and end up in a sludge we call paper sludge. This paper sludge is a valuable resource for many industries, both as an alternative fuel as well as an alternative raw material. Lignite boilers co-combust paper sludge, taking benefit from both the heating value as the calcium which is in the paper sludge.Read more >
RDF – abbreviation of refuse derived fuel – is a fuel that is produced from a combination of non-recyclable commercial and industrial waste. This fuel contains different types of plastics, textile, rubber, wood and paper. Recyclables, such as glass and metal, are taken by waste sorters. Read more >
Subcoal® is a technology to upgrade RDF and SRF into pellets. Subcoal® pellets replace e.g. lignite, bituminous coal and pet coke in power plants and in lime and cement kilns. The chemical composition of Subcoal® pellets is comparable to bituminous coal in terms of heating value and it can be treated the same physical way. Read more >
SRF – abbreviation of solid recovered fuel – is RDF upgraded to a fuel that consists of smaller fractions and more energy content. Processing RDF further upgrades the waste material, first more recyclables are taking out and then the non-recyclable residue is being used as fuel which is mostly suited to replace primary fossil fuels. Depending on the quality and application, SRF can substitute at least 70% of the primary fuels, used in a kiln or boiler.Read more >
TDF – abbreviation of tyre derived fuel – consists mostly of rubber, e.g. shredded car and truck tyres. The rim is getting removed from the tyre, after that the tyre gets shredded into 2 inches fluff and smaller material. Cement kilns are TDF’s end users. The material replaces fossil fuels, such as lignite and bituminous coal. Read more >
