Special Feature: 2018 NIIEX show highlights

The recycling of waste material, whether food, metal, plastic or other, is becoming big business across the world, as well as being a vital component in protecting the environment.
Handling waste can be a complex task, but thanks to innovative minds and new technology there is a huge range of machinery on the market that can assist waste processing.
It is certainly a sector that many machinery and equipment manufacturers are becoming increasingly involved in as demand for waste handling machinery grows. There are, however, not so many mainstream exhibitions of this machinery held around the world, but that trend is changing fast as the popularity of recycling increases.
One recent event showcasing some of the latest machinery available was held in Northern Ireland where a number of the products on show are being replicated and indeed exported to many cities around the world.
On display at the NIIEX show were a number of different trucks, many of which had been transformed into waste collection vehicles, and a few exhibiting how versatile they can be with fitted bodies.
COOKING WITH GAS
One of the more interesting concepts highlighted at the show was how an increasing number of cities in the UK are using biogas-powered trucks to collect food waste, deliver it to an anaerobic digestion (AD) plant and then refuel on the very gas being produced by that plant.
MacPac Refuse Bodies Limited is based in
Antrim, Northern Ireland, and manufactures the truck bodies that collect food waste, amongst other equipment. Sales manager David Hyde says there is a big movement towards gas (compressed natural gas) powered vehicles for food waste collection, particularly in cities and towns.
This will give the truck enough fuel to run approximately 200 miles (322km).
“We are seeing increased demand to fit our bodies onto Iveco trucks that run on gas,” he says.
“It is a green circle as the trucks can fill up on the gas produced by the AD plants, manufactured from the food waste they deliver there.
“The Iveco trucks are based on a 16-tonne chassis and our body on the back has a 7.5-tonne payload of food waste.
“It takes around one tonne of processed food waste to make enough gas to fill up one tank on the truck.
“This will give the truck enough fuel to run approximately 200 miles (322km), which is a few days’ use in some cities depending on the length of the journey from the food waste collection point to the AD plant.
“We have already sold three of these units into Northern Ireland and eight into England, all to private contractors.”
One of the larger pieces of machinery on display was the Terex TWH220 materials handler, exhibited by Irish dealer McHale Plant Sales.
Sales manager Paul Mullally outlined the benefits of this machine that is proving popular in the recycling industry.
“It has a reach of up to 9.2 metres and is powered by a 95kW engine. Overall the Terex TWH 220 weighs in at 22.9 tonnes and uses state-of-the-art engine and cooling technology,” he says.
Terex says the divided cooling system on the TWH 220, comprised of a hydrostatically driven fan for the oil cooler and a viscous-clutch driven fan for the water and charge air cooler, provides silent cooling and permits operation of the machine at temperatures as high as 50°C.
Options such as additional suction boxes or a pressurised cabin system with a protective ventilation system are provided to facilitate
operation in the sorting hall. Optimal visibility is afforded both by the lifting cab with its panoramic windows and by the advanced function monitor, which permits comprehensive surveillance of all operating data.
Ergonomically-arranged operational controls and a comfortable seat that provides lumbar support are components of the basic equipment.
One of the other exhibitors, AEBI Schmidt UK Ltd displayed a number of options for road sweeping.
UK area sales manager Diane Curran says the Swingo compact sweepers and the Street King range of larger sweeping units were very popular.
“The Street King 660 truck mounted sweeper has a hopper capacity of seven cubic metres and a dual sweep width of up to 3.5 metres,” she says.
“This particular example is mounted on a DAF LF220 sweeper chassis powered by a Deutz 75 horsepower engine. These are most commonly used by councils or private contractors and have proven very reliable with them.”
Show organiser Raymond Martin from Greenbridge Innovations is pleased with how the show went.
“This is our second show here relating to the waste and recycling sectors and we continue to grow each event,” he says.
“There is a developing interest in the machinery and services dedicated to the waste, recycling and shredding industries across the world and therefore a big need for show like this. It is a specialist show for the industry and we are happy with the number of exhibitors and visitors, but already have new plans to further expand these next year.”
