Applications
Industrial Shredding Systems Limited has specified, installed and maintained shredding systems for a wide range of applications including hazardous waste, tyres, metals, plastics, demolition debris and eScrap as well as high-level confidential data destruction. Customers are equally as diverse from recycling operations to multi-national corporations.
Wood - There are no cross industry standard specifications for wood recycling. Timber recyclers generally will accept nearly all soft and hardwood materials including pallets. Plywood is also accepted. Restrictions are imposed with regard to contaminants. Metals are divided into two categories: ferrous and non-ferrous. Ferrous contamination such as nails and screws is usually acceptable — these can be readily removed by magnetic extraction.
Landfill - We have engineered many solutions for landfill operations
and built shredding systems to reduce material prior to compaction for
transfer and built onsite shredders for use at landfill sites. In each
case, shredding greatly improves the efficiency of the transported waste
and extends the capacity and life of the landfill.
The European Landfill Directive has set tough targets for the reduction
of biodegradable municipal waste (BMW) landfilled: by 2010, it must be
just 75% of that produced in 1995, by 2013 it must be 50% of the 1995
figure, and by 2020, BMW landfilled must be just 35% of that produced
in 1995. On top of this, the Waste Strategy 2000 set the UK the target
of composting or recycling 25% of household waste by 2005, 30% by 2010
and 33% by 2015.
Composting - For municipalities that have organic waste recycling programs,
Industrial Shredding Systems Limited has provided shredders to meet specific
needs. Some composting operations require only larger strips, others feed
the waste through a series of shredders prior to processing through a
high-speed mill.

Thermal Treatment - Operations that incinerate waste, whether for simple destruction or the burning of alternative fuels for energy, have found our shredders vastly improve the combustion efficiency of the material.
Size / Volume Reduction - Shredding of metals for volume reduction can simplify material handling, minimize storage space and reduce transportation and disposal costs. Industrial Shredding Systems Limited has built shredders to process light scrap in a metal recycling yard, or materials generated by a manufacturer, such as aluminum extrusion from a door or window manufacturer. Our shredders have also been used to prepare metals to feed into high speed hammermills.
Recycling / Remelting - Metals destined for recycling are often baled or briquetted to facilitate handling and reduce transportation costs. However, once material arrives at the processing facility, processors often wish to shred bales or briquettes to improve furnace feeding and the efficiency of the remelting or delacquering process. Shredding also helps to liberate trapped contamination, upgrading the quality of the metal and its value.
Precious Metal Recovery - Electronic scrap including computer drives, monitors, telephone switching gear, and circuit boards contain precious metals such as gold, silver and platinum. Recovery facilities have used low-speed shredders to preprocess bulky components to make it easier to liberate metals.
Tyres - From high-volume Tyre Derived Fuel (TDF) to lower volume rough shred operations, Industrial Shredding Systems Limited has a reputation for reliable and productive tyre shredding systems. Our shredders process passenger, truck, off-road, heavy equipment and aircraft tyres. Our TDF systems can process tyres at rates up to 25 tph. Most operations make 1"-2" at 5-15 tph.
Tyre shredders can also be configured for mobile or stationary operations. Under the European Landfill Directive, whole tyres can no longer be sent to landfill for disposal. From July 2006, this ban also extends to shredded tyres.
Paper - Industrial Shredding Systems Limited addresses a broad range of paper shredding applications, including loose or boxed office paper, books, magazines, baled paper, stacked sheets, and rolls of paper. We have built mobile or stationary shredders for publishers to destroy returned, misprinted, or outdated books as well as for companies to destroy paper files for security purposes. Our shredders are frequently used to shred scrap paper prior to baling. Shredding facilitates handling and makes the bale density more consistent. Very sensitive documents are often processed into an extremely small particle by a high-speed mill (granulator, disintegrator or knife mill). Pre-processing material in a low-speed shredder first can increase the entyre system's capacity whilst reducing wear and damage to the high-speed mill. Shredded paper is easier to handle and meter-feed into an incinerator. Shredding also allows the paper to burn more thoroughly and rapidly. Our shredders are also ideal for shredding baled paper and cardboard prior to hydropulpling.
Producing recycled paper involves between 28 - 70% less energy consumption than virgin paper and uses less water (Waste Watch) For every tonne of paper recycled 17 trees are spared; 7,000 gallons of water are saved and 4,200 KWh less electricity is used (Waste Watch). These statistics alone prove that recycling is vital if we are to preserve the Earth's natural resources.
Plastics - Shredding plastics prior to granulation facilitates handling, increases efficiency, and saves the high-speed granulator from wear and damage. Purgings are loosely formed masses of plastic that have been discharged from plastic processing equipment following a material or color run. Although these materials can be processed for re-use, they are often too large to be processed by granulators alone. Pre-shredding these purgings facilitates granulator feeding and reduces "slamming" (or heavy impact) and its effect on equipment performance and maintenance. Typical plastics we shred include PET (Polyethylene terephthalate), HDPE (High-Density Polyethylene), PVC (Polyvinyl Chloride), LDPE (Low-Density Polyethylene), PP (Polypropylene), PS (Polystyrene), Unsorted resins and plastics.
Textiles - whether they come in the form of rolled carpets, furniture, mattresses, or cloth, tend to unravel and wrap around the shafts of conventional shredders, causing them to jam. We has developed shredding systems that are specifically designed to deal with this inherent problem, cutting textiles into small pieces rather than long strands.
Construction & Demolition Debris - the SSI Pri-Max shredders have been specifically designed to shred, tear, and break bulky debris into manageable pieces that are easy to transport and economical to dispose of. PRI-MAX shredders process between 1-150 tons per hour while achieving up to 80% volume reduction. The heavy-duty, open-grate design of the cutting table allows fines, such as rock and dirt, to fall through, reducing wear on the cutters. The design and materials of the PRI-MAX ensure longer life and lower operations and maintenance costs.
Electronic Scrap (eScrap) - Until recently, the process of reclaiming precious metals from electonic scrap involved the labor-intensive process of dismantling of components manually to extract the precious metals. We have developed shredding systems to make this metals-liberation process far easier and more economical, allowing e-scrap recyclers to accelerate the payback from their investment. The Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC adopted by the European Union (EU) in 2003 along with RoHS requires producers to provide recovery and recycling programs for the processing of waste Electrical and Electronic Equipment (EEE).
Hazardous Materials - Industrial Shredding Systems Limited offers fully integrated, custom designed systems for effective pre-processing of hazardous wastes.
Drummed and
bulk wastes enter the system, passing through a double-door airlock. Material
is then processed through two hydraulic shredders. Following the size
reduction process material is then discharged to downstream equipment
to complete the blending process. Types of Hazardous Materials shredded
include dry solid waste, drums with contents, solids & liquids, household
hazardous waste, aerosols, paints, sludges, radioactive waste and nuclear
fuel rods. Safety features include class I, divisions 1 & 2 environments,
explosion-proof motors and controls, inert gas purging, oxygen monitoring,
fire detection and suppression, deflagration vents, double door airlocks,
video monitoring and complete operator control system.
Confidential Data Destruction - With new legislation placing more requirements on institutions to protect personal data helping to eliminate identity theft, we have a range of shredders that are ideal for information security destruction. Manufacturers can shred defective, mispackaged, or date-expired goods to prevent theft, thereby reducing associated losses and liability risks. Waste materials (or defective products) can be shredded to allow recycling or re-use. Wastes generated in manufacturing process such as plastic, rubber, or fibers are ideal candidates for reprocessing. Packaged goods can be shredded to open containers. Contents such as detergent can be collected and separated for repackaging, while contents such as canned food can be separated and reprocessed into animal feed.
Medical Waste - we can offer fully integrated, custom designed shredding systems for destruction of a variety of medical wastes including red bag, linens, plastic sheets, latex gloves, syringes and sharps containers and boxed medical waste.
