Global Advanced Recycling has developed the KDX-Eliminator, which blasts non-metallic recyclate into micron-sized particles
What is your product?
The KDX-Eliminator from Global Advanced Recycling.
How does it work?
The KDX-E is a nonagon-shaped steel chamber, lined with ceramic tiles as used on the outside of space re-entry vehicles. In it are 16 impellers and up to 32 vortex generators mounted on four discs attached to a central vertical shaft. The shaft rotates at 1,200rpm, creating multiple intense continuous vortices in air moving through the chamber at 500,000 cubic feet per minute, reaching a speed of Mach 0.9. Unsorted waste introduced into the airstream is reduced by mid-air kinetic impacts. At the same time, the kinetic effect of the collisions removes up to 50% of the moisture in the waste. A further 20% is removed as the wastes are propelled in the jet-stream to the cyclonic filtration system. Municipal Solid Waste (MSW) can be reduced to flock at the rate of one tonne every 26 seconds.
Where would it ideally be used?
KDX-E can be used in any application that requires the reduction of any non-metallic substance to micron sized particles. Apart from waste management, KDX-E can be used in: mineral extraction and mining to separate metal out from ore; food processing, to turn grain into flour; paint production to reduce glass for reflective paints; domestic tile production to reduce unwanted scrap tiles to powder for recycling; and almost any energy-from-waste process. It is also expected to have applications in quarrying, cement production, agriculture through the production of soil stimulants from organic waste, and pharmaceuticals.
How is it different?
The KDX-E has no mechanical impactions. The input waste is moved around by the combination of high-speed vortices set up in the chamber. Over 80% of the feed stock will be suspended in the air, continuously impacting against millions of particles in the vortices. Each time they collide they will explode into smaller fragments until they are reduced to micron size, and are expelled with the air flow.
What benefits does it offer?
It converts heterogeneous materials to uniform powder in a single process. There are no toxic or pollutant emissions so there is nothing left to go to landfill. The process is carbon negative and makes mining of existing landfill sites possible and profitable. It can reduce waste in landfill by at least 80%and thus increases the life of any existing landfill by a factor of five. The system replaces costly machinery such as ball mills, hammer mills, pulverisers and dryers and offers significant savings compared with any other comparable technology available today.
Where has it been used?
The principle has been applied in machines employed by the US Military for over 35 years to reduce rocks to dust to be used in road building. The flock produced by the KDX-E from MSW can be blended with resin to make kerbstones, paving slabs, noise absorption boards and building blocks. The organic residue can be separated out, leaving a nutrient and mineral rich compost for parks, gardens and golf courses. The Eliminator was used to reduce landfill in the US in Dodge City, Kansas.
The cost per unit of the complete KDX-E ranges from £980,000 to over £1.5 million, subject to the application for which it is intended. It comes with a performance guarantee.
The KDX-E offers a reduction of at least 60% in operational expenditure compared with alternative systems. It produces uniform feedstock for onward processing, offering up to 40% greater yield than current alternative systems. In a large MRF, KDX-E needs only one person to operate it: a significant manpower saving compared with current alternatives.
What about maintenance?
The KDX-E needs to be cleaned out using high-pressure air after each 8-hour shift. This takes about 20 minutes on average. It requires maintenance taking about 24 hours every year of operation, costing about £2,000. It self-monitors electronically on a constant basis to detect any potential developing faults or drops in performance.
What is its life span?
The KDX-E is expected to last about 25 years in regular operation.
How is it future-proofed?
The KDX-E is adaptable for use in almost any industry. GAR Company has developed and refined the design continuously over several years. Research and development are ongoing.
KDX-E is an all-in-one processor that replaces older technologies with benefits in both cost and efficiency. Its footprint is only 13 square metres, and it weighs 12 tonnes.
