Materials

Domestic waste

Residual waste is optimally handled by shredding it in mechanical-biological waste treatment plants (MBT) and separating the various recyclable materials from each other. Another use of residual waste is thermal utilisation in a waste incineration plant. The heat released is used both to generate electricity and to provide heat.

Domestic waste

Typical residual waste from households offers little potential for material recycling. However, in the cement industry, the high-calorific fractions from the waste can be used as an alternative fuel. RDF manufacturers filter out these fractions by shredding and separating them.

Bulky waste

Largely homogeneous RDFs with good combustion and low pollutant properties can be produced, even from bulky waste.

Waste wood

The processing of waste wood transforms wood waste of various types into a valuable secondary raw material. Besides the recovery of materials, efficient energy recovery is becoming increasingly important as a renewable energy source.

Bulky waste

Bulky waste chiefly includes discarded furniture, mattresses, wallpaper remnants and old carpets. Nowadays, most bulky waste can be recycled for materials and energy.

Industrial waste

The non-recyclable materials from waste generated in industry and commerce can be processed into RDFs and used in power plants or the cement industry.

Bark

Bark can be thermally recycled as fuel and further processed into bark mulch or bark litter.

Industrial waste

Commercial municipal waste (also abbreviated to commercial waste) is municipal waste from sources other than private households, in particular commercial and industrial waste as well as waste from private and public institutions. This waste is similar to waste from private households due to its nature or composition and must be disposed of in the same way.

However, commercial municipal waste also includes other production-specific waste from other sources, such as workshop waste, cleaning rags containing mineral oil, paint buckets or non-infectious waste, leather waste, metal waste, including shavings from metalworking and metal processing.

Straw bales

Direct feeding of entire strawballs to shredders for downstream processes in energy and materials recovery offers several advantages. The work of unravelling the strawballs in advance is no longer necessary. Systems for the storage, conveyance and metred feeding round off the product portfolio for processing technology.

Sorting residues

In sorting plants for light packaging (LVP), the packaging items pass through various packaging items pass through various stations, at each of which a specific fraction of the material is sorted out of the material flow. Pressed into bales, the individual material fractions are then sent for recycling. Waste designation Sorting residues: Sorting residues from facilities for sorting lightweight packaging, so-called DSD sorting residues. These can be processed into alternative fuels in substitute fuel processing plants.

Waste wood, used wood

Wood waste or even old pallets can be used as a renewable raw material for energy production. Effective processing is essential to produce a waste-based RDF.

Biomass

Residual materials are chiefly used as solid biogenic fuels – in other words, biomass that is hardly suitable for purposes other than incineration. For example, these materials include forest and industrial residual wood, waste wood, garden and park waste and straw.
