Commercial & Industrial Waste Shredders (C&I)
Information about shredders for shredding and processing of commercial and industrial waste
The recycling of industrial and commercial waste should and must be of ever higher quality, entirely in the sense of a sustainable materials cycle. Companies must adapt their waste management accordingly. Commercial waste, for example, is to be separated at the same place where it is generated. The documentation requirement has also been extended.
Commercial municipal waste can be very similar to private household waste. There is paper, biomass, glass, metals, textiles, packaging, residual waste and films. One major difference, however, is the treatment of hazardous waste.
Most material streams, whether they are recycled or thermally recovered, must first be shredded in one or more stages. This requires particularly robust machines, as foreign materials such as stones, sand and metals may be present. WEIMA offers the right shredders for this first process step: shredding. With a variety of large rotor widths, many heavy-duty options and drive concepts have been especially designed for these applications. Of course, we also offer complete plant systems from a single source. The result: safely and cleanly processed, homogeneous material streams. These are made usable as refuse derived fuel (RDF) or solid recovered fuel (SRF) for the cement industry, pre-processing or co-processing.

What is industrial waste?
When the processing of industrial goods produces residual materials that cannot be further processed, this is referred to as industrial waste. The largest quantities of industrial waste are generated by mining, the chemical industry and the construction industry. This includes construction waste, plastics and industrial sludge. Reusable material streams are recycled, which significantly reduces the amount of waste. Often, industrial waste also consists of hazardous waste, which means that it is then sent to a waste incineration plant for energy generation.
What is commercial waste?
If you compare commercial waste with waste from private households, you will notice that they are not all that different – which is why they are sometimes referred to as commercial municipal waste. As a rule, it originates in commerce, trade, industry or public institutions such as hospitals or government offices.

Post-industrial film shredding with a WEIMA W5.22 @ EcoFib, Canada
A WEIMA W5.22 shreds post-industrial film at EcoFib in Canada.
Once all material streams have been cleanly separated, sorted and shredded, they can be passed on to recycling companies. Used packaging films can be turned into new ones again, just as used paper can. Waste wood, for example, can be used for chipboard production. Those materials that cannot be recycled (due to pollution or other contamination) are ultimately fed into energy and heat generation – although this rate is expected to drop significantly. The primary goal remains the circular economy.
Challenges in the shredding of commercial and industrial waste
Our industrial and commercial waste sometimes contains materials and things that do not belong there – and it makes processing correspondingly difficult. These include stones, soil, large pieces of metal, sand, ash, or pollutants of various categories. So the better the pre-sorting, the less wear can be expected during the shredding process. Nevertheless, maximum robustness, powerful drives and easy maintenance are and remain the trump cards for industrial shredders in order to avoid unpleasant downtimes. Here, WEIMA can rely on a broad and decades-long wealth of experience.
Stand-alone operation or integration into a production line
Unlock your waste-to-energy potential! Depending on your requirements, we supply you with the right shredder for your shredding task. If required, WEIMA also offers a multi-stage system solution in the form of a plant. We are assisted in this by an extensive supplier and service network that we have built up over the past 25 years.
This network is comprised of specialists from the fields of conveying, sorting, separation, screening, washing, metal detection, extrusion, heating and granulation. As a joint project team, we have already mastered hundreds of major tasks all over the world.
Alternative fuels for cement production
The cement industry has a very high demand for energy. This can increasingly be met with refuse-derived fuels. The focus is on the combustion of alternative fuels in calciners, preburners and kilns. In order to reduce energy costs, cement manufacturers are increasingly focusing on increasing the proportion of alternative fuels used in energy production. Compared to conventional materials, the thermal utilization of alternative fuels has better physical combustion properties and better burnout in the kiln. In general, the better the alternative fuel used, the more efficient the production of high-quality clinker.

What is Pre-Processing?
- As a rule, waste cannot be used directly for recycling in cement kilns, but instead they must be prepared beforehand. The treatment process, also called pre-processing, includes the shredding, mixing and drying of waste. The use of WEIMA shredders in pre-processing enables consistently homogeneous particle sizes of the most demanding material. This guarantees a stable fuel that meets the technical requirements of cement production.
What is Co-Processing?
- The term co-processing describes a globally recognized technology used in energy-intensive industries (EII) such as cement production to recycle waste and industrial by-products for energy and materials. The mineral materials in the waste replace primary raw materials (e.g. limestone) in the cement kiln, while the combustible materials provide the energy needed to produce clinker. No residues are produced in the process, and highly toxic waste is also destroyed. Co-processing thus makes it possible to avoid landfilling and waste incineration of wastes such as sewage sludge, solvents, plastics from industry or mineral wastes.
What are the advantages of Co-Processing?
- Co-processing in the context of cement production has many advantages: The high temperatures and long residence time in the kiln completely destroy even toxic residues. No residual materials are produced that have to be recycled or even landfilled. The use of co-processing technology also avoids the use of fossil fuels and consequently reduces greenhouse gas emissions. In addition, cement manufacturers can massively reduce their energy costs thanks to secondary fuels from waste.
What is Solid Recovered Fuel (SRF)?
For the production of Solid Recovered Fuel (SRF), additional process steps are usually necessary, as higher quality requirements for its production have been defined at European level. The essential properties of a classification include the calorific value as well as the chlorine and mercury content. This results in five quality classes in order to be able to designate processed waste as Solid Recovered Fuel.

What is refuse derived fuel (RDF)?
WEIMA waste shredders are ideal for the production of medium and high calorific RDF (refuse derived fuel) or calciner fuel. These are fuels obtained from household, industrial and municipal waste. The different quality requirements depend on the thermal process. Typical processing steps for the high-calorific fraction include pre-sorting, pre-shredding, air classification and metal separation. Sensory sorting and drying are also possible. In most cases, refuse-derived fuel is used together with conventional fuels, e.g. in cement, lime, coal and industrial power plants.

How does the Mechanical-Biological Waste Treatment (MBT) work?
This generally involves household waste, MSW or commercial waste similar to household waste. This is initially collected by disposal companies and transported to a central location for waste treatment, disposal or recycling. Typically, household waste contains a high proportion of organic matter. After rough screening, this is shredded and then divided into different fractions by screening. The coarse fraction (films, paper, hard plastics, wood, etc.) is usually used as fuel in RDF power plants because of its high calorific value. The fine fraction (organic substances), on the other hand, is usually further biologically treated. Gases produced in this way can be used for energy.
PowerLine: universal shredder with single-shaft technology for pre- or post-shredding
Performance that pays off. The PowerLine series takes on any form of waste, even contaminated materials. Ideal as a shredder in multi-stage plants: After sorting out materials not suitable for RDF, the pre-shredded material can be optimally processed in the secondary shredding stage. The PowerLine can be equipped with hydraulic drive, direct drive or power belt drive.
