    Mixed Municipal Solid Waste Sorting

    Traditional (manual) or semi-automated techniques, however, are only able to recover low levels of separate materials from mixed municipal waste streams and mean considerable content going to landfill. In contrast, TOMRA Sorting’s fully automated, state-of-the-art, sensor-based municipal sorting systems convert complex and varied - even dirty - municipal solid waste streams into high quality, separated, marketable output. The systems also make manual sorting unnecessary, thus reducing labor costs and material loss, while increasing efficiency. Operationally, through using detection techniques such as near infrared (NIR), x-ray transmission (XRT), color line cameras and metal sensors in combination.

  • SRF

    SRF Manufacture is an alternative fuel produced by shredding and dehydrating solid waste, typically consisting of combustible components of solid waste, including paper, card, wood, textiles and plastic. It can be produced to a range of specifications to meet customer requirements. Solid Recovered Fuel Manufacture The materials used to produce Solid Recovered Fuel pass through a series of shredders, screens, air classifiers/density separators and magnets. Inert materials, recyclable plastics and metals are extracted from the shredded material, leaving a mix of mainly non-recyclable paper, card, wood, textiles and plastic. Although a small proportion of these materials can be recycled the quality of these materials is compromised once they enter the residual waste stream and recovering energy from these materials is currently the best environmental option.

  • Classification and identification of recyclable material

    This level is expected to reach over 4 million tons by 2010. Companies that specialize in recycling carpet require a fast, reliable and accurate means of identifying the carpet face fiber type entering recycling streams. Collection of plastics for recycling is increasing rapidly. Plastic recycling faces one huge problem, plastic types must not be mixed for recycling. Even a small amount of the wrong type of plastic can ruin the melt. Whether it is a carpet or plastic, classification and identification of recyclable material can be achieved using Bruker Optics` state of the art spectrometer systems. Bruker Optics has applied the FT-NIR technology and experience to this demanding requirement, and offers the Carpet Analyzer as a dedicated solution for the recycling industry.

  • Systems for the product/material destruction industry

    Product destruction can be a tricky undertaking. Not only do you have a mixed material stream to manage, but you also need to extract and discard the contents of those materials before they can be recycled. Every operation really does require a custom solution that works best for your demands. From deliquifying bottles and cans, to destroying poor-quality or outdated products, OBC has the experience to help you determine the most efficient and effective process to achieve your goals. Keep your workplace environment clean and sanitary, and maximize profit by maximizing throughput.

  • Waste water respirometry solutions for toxicity tracking

    If toxicity is identified in a mixed sewage entering a treatment works, the problem for the plant manager is to track and identify the source of the toxicity. This can be done by sampling the effluent stream at various points in its length. By working in a logical sequence back up the sewer network the number of samples can be minimised. This type of testing should be rigorously enforced for new product introduction by a waste producer, as well as sampling the effluents directly at source. The samples would be tested against the activated sludge of the receiving works, using the Respiration Inhibition Test or the Nitrification Inhibition Test.

  • Biological wastewater processes for mining

    The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is acceptable for re-use, reducing the stress on ecosystems in water stressed areas.

  • Oil water separation for the food industry

    Packaged-food producers frequently use and then must discard large batches of cooking oil used in their process. Usually they drain most of the oil directly from equipment, but they must remove residual oil by regularly washing fryers, ovens, conveyors, and other machinery. 

    The oil mixes with the wash water and becomes part of the plants wastewater stream. Having oil in wastewater complicates the wastewater-treatment process by making it more expensive, more time-consuming, and less effective. Additionally. as with other manufacturers, packaged-food producers want to reduce waste and decrease the environmental impact of operations. That is why removing used oil and solids from wastewater before it is discharged is a priority.
