NRAs 2015 Innovation – Equipment: Finalists

Untha XR waste shredder

XR waste shredder (above)

After four years of pioneering R&D, design, engineering and testing, Untha has created a robust shredder capable of producing a high-quality renewable energy source in a single pass. With higher tonnages, lower power consumption, less noise and less cost, the shredder enables energy-from-waste operators to produce an alternative fuel, exactly to specification, while maximising profitability and minimising environmental impact.

Green Grinder (below)

The Green Grinder, developed by 2G Environmental, is an advanced recycling machine and process for new-build construction sites. It can save the builder/developer 50-57% of costs over traditional waste management skips.

The GG processes 85% of site waste and eliminates 85% of skips, reducing the site’s CO2 footprint, eliminating skip lorry traffic and cutting waste to landfill.

Solar Pac

Pearce Compaction Systems has designed a solar-powered waste compactor for use in a commercial environment. The technology can be fitted to a static or mobile compactor without compromising any of the standard features. Solar Pac comprises four 250W solar panels which charge four gel-filled batteries that power the machine – even if there is no daylight for 10 consecutive days, the Solar Pac will function as normal. The energy- efficient compactor uses only 2.21kW of power, and is a completely off-grid system that has zero running costs.

CD&E waste recycling plant

In May 2014, CDE Global embarked on a project backed by the EU’s Eco-Innovation Fund with the aim of enhancing infrastructure for the recycling of construction, demolition and excavation (CD&E) waste. The project operates under the acronym Candy (CompAct, highly mobile, Next generation, CD&E waste recoverY system), and saw the introduction of a system in Stuttgart, Germany, which delivers on key objectives including reduced plant footprint, enhanced mobility and an increased return on investment from CD&E recycling operations. The CD&E plant produces a range of recycled sand and aggregate products. 

Hospital waste collection solution

Taylor Bins and Swisslog’s automated guided vehicles (AGVs) delivered a fully automated waste collection solution for North Bristol NHS Trust’s Southmead Hospital. Twelve AGVs transport 158 custom-built Taylor bins around the £430m building. The result is a cleaner and more sustainable approach to waste collection; increased hygiene levels as physical contact by waste collection operatives is minimised; reduced manpower allowing the hospital to reinvest any savings in patient care; less wear and tear on the new hospital; reduced accident risks; and less risk of hospital-acquired infections.


Cleanergy’s GasBox has been developed to generate electricity and heat from the methane gas being emitted at the UK’s more than 20,000 landfill sites which are more than 10 years old. Methane is channelled into the GasBox where it is combusted in an external chamber. The hot gas expands and moves the piston, after which it is cooled and then reused in the stirling cycle. In this process, the working gas temperature fluctuates and moves the piston and crank shaft to produce electricity. Excess heat emitted during combustion is also captured and used for heating water.

SmartBin intelligent monitoring

SmartBin is transforming the way companies service their containers. The solution harmonises a fill-level sensor and routing software platform to enable collectors to know the fill-level of their bins/containers at all times and dispatch their fleets on optimised routes only. The results are up to 50% reduction in collection costs, smarter and more agile operations, and streets that are free of trucks and over-filled bins. SmartBin is a ‘smart city’ solution that is now proven in 25 countries.

Prism: Plastics and Packaging Rapid Intelligent Sorting System for Materials (below)

Nextek’s Prism is a way of rapidly sorting packaging based on intelligent labels with invisible markers that can be detected and sorted using existing high-speed optical sorting systems used in MRFs. The technology uses commercial labelling and decoration methods to sort targeted streams. Sorting is accomplished using modifications to existing NIR sorting machinery. The technology can boost recycling plant yields and increase recovery of food-grade plastics to open up new markets for recovered plastics.
