Galliford Try selects Saxlund Push Floor fuel solution for three waste wood gasification facilities

2017 05 18 093120Saxlund International was selected by principal contractor Galliford Try Infrastructure in May 2016 to provide the bulk fuel reception and handling technology for three waste wood gasification facilities currently under construction in Barry, Boston and Hull, for renewable energy company Biomass UK. Saxlund is now on site in construction on all three sites.

With these 3 contracts, Saxlund is now contracted to deliver 13 alternative fuel handling systems in the UK by the end of 2017. This is over 50% of current UK projects in construction. This amount of construction involves vast quantities of equipment such as 1.5 km of Push Floors Ladders (if placed end to end) and the combined volume of push floors covering 10 tennis courts and storage areas of biomass/RDF totalling nearly 4 Olympic sized swimming pools.

With a combined contract value of £2.6 million, Saxlund is responsible for the design, manufacture, installation and commissioning of similar fuel handling systems at each site. This includes Saxlund’s Push Floor reception and storage system, discharging into a conveying and screening system to feed fuel into twin gasifier bins at each site.

2017 05 18 093137Each system will provide on-site buffer storage for approximately 600m3 of waste wood and is designed to discharge some 100,000 tonnes of fuel per annum. Future proofing each site to take account of changing fuel characteristics has been a key focus and while each site is designed to work initially with wood chip, Saxlund’s design will accommodate alternative fuel sources.

The fully automated state-of-the-art Push Floor technology is based on ‘first in, first out’ principles, specifically designed to limit the opportunity for the fuel to degrade or compact. This in turn ensures a resilient on demand process with discharge, conveying and weighing system, feeding the fuel to the gasifier feed bins.

With project completion expected in the second half of 2017 the three plants will have a combined export capacity of 30MW to the national grid.

Matt Drew, Managing Director of Saxlund International said: “We’re delighted to be working with Galliford Try on these installations for Biomass UK. As an approved supplier we have been involved from the earliest stages on pre-contract and design development to ensure highly resilient on demand fuel handling solutions for each site.”

Spanish facility set to process 20,000 tonnes of waste per year

Waste management specialist Madegan is in the final stages of commissioning a new shredding system that will enable the family-run business to process up to 20,000 tonnes of waste per year.

The Spanish organisation is no stranger to the waste and recycling market, having its roots in the late 1970s. But fast forward to 2017 and continued growth and innovation means Madegan is now a well-known name in the world of waste to energy.

The team therefore sought a new machine to boost the capacity and flexibility of their Madrid facility.

2017 05 15 071929

Following an extensive three year research project, Madegan headed to Austria to visit the global shredder manufacturer UNTHA. Impressed with the operational capabilities and performance of the machine, plus the vastly reduced energy consumption, Madegan procured the XR mobil-e – a new shredder that has quickly become renowned for its ability to efficiently process a variety of wastes.

Luis Silva from UNTHA IBERICA explains: “When discussions first began, our local sales team worked with Madegan to understand the requirements of the project. They have been shredding waste since 2005 but as they continue to expand, they need to be able to handle higher volumes of different material streams.

“We helped them devise a new shredding solution that can tackle everything from commercial and industrial (C&I) waste, to construction and demolition waste, wood and municipal solid waste (MSW). They then travelled to our global headquarters near Salzburg – not just to see the XR mobil-e in operation, but to trial it with their own materials too.”

The technology soon proved it could handle the waste with ease, to manufacture a high quality SRF product. But the business case for the mobile machine was also strong.

“This was a very important economical investment for us,” elaborates Alberto Magan, CEO of Madegan. “We therefore looked at everything, ranging from the initial cost of the machine, through to the speed and ease of maintenance, typical uptime rates, throughputs, energy efficiency and adaptability to meet varied customer specifications. The stats, coupled with the promised longevity of the machine, made the XR the most solid investment.”

When fully operational, the shredder will allow Madegan to process a number of waste streams down to a homogenous particle size of 30-40mm. Supplied on tracks and with an in-built conveyor, it can easily be moved around the Madrid site, and plugged back in.


UNTHA reveals third generation waste shredder

Global shredding giant UNTHA has launched its 3rd series XR waste shredder, following more than 10 years at the forefront of this progressive industry.

The UNTHA XR was first brought to market as a robust pre-shredder that could effectively process a myriad of municipal, commercial and industrial wastes in readiness for the alternative fuel production market.

But committed to strengthening the profitability of clients’ operations – not just their functional capabilities – the Austrian-headquartered team continued to innovate. In 2014, a ground-breaking shredder was released that could manufacture SRF in a single pass. This feat of engineering halved operators’ capital outlay and reduced energy consumption by up to 50%, without any detrimental on throughputs, uptime or product quality and saving. Typical savings of hundreds of thousands of pounds also began to be recouped. A ‘moveable’ version of the technology was brought to market in late 2015, when the XR became the world’s first electrically-driven mobile shredder with the same bottom-line benefits.

2017 05 09 103006

However, knowing the XR was still capable of so much more, the research and development continued in UNTHA’s Innovation Centre in Kuchl, near Salzburg. And, following extensive trials throughout Europe, a 3rd series waste shredder has now been revealed.

Whilst aesthetically the machine has the same sleek construction as its predecessors, it is the internal workings of the technology that have been refined to enable the XR to handle a wider range of input materials and achieve even more impressive performance figures than before.

Different cutter configurations, torque settings and motor modifications mean that one day the shredder can be producing a p63-specification biomass fuel with low fines output from waste wood, for example. The next it could be manufacturing a high quality SRF with homogenous <30mm particle sizing, before going on to achieve a 75mm gasifier material – all in a single pass, and all with this one piece of equipment.

UNTHA’s head of the waste shredding division Peter Streinik explains more: “We have always known the capabilities of the XR are virtually limitless. We are a problem-solving team hungry to engineer ever-smarter solutions for the global waste market as it continues to push new boundaries. But, as with many technological industries, the process takes time.

“The evolution of the XR has therefore been an iterative process – this 3rd series machine has been 3 years in the making and has taken months of trials and €1,000,000 to perfect. But now we have a truly remarkable shredder with flexibility like no other equipment in the marketplace. It can tackle everything from ordinary commercial waste through to incredibly complex applications like pulper ropes. And we’ve designed the machine so that it achieves the throughputs achieved by a higher speed shredder, with far lower wear rates, operating costs and energy consumption.”

It seems that the message from UNTHA’s HQ is that anything is possible. “Whether clients opt for a static or mobile machine, the beauty of the new XR is the breadth of its capabilities,” continues Peter. “The build and rigidity of the kit, along with its in-built protection from ‘unshreddables’, has opened up a whole new world of opportunity. We’re even configuring one machine that gives excellent recovery rates when using optical sorting equipment within a MRF or fuel preparation line – this would have previously only been possible using two shaft technology.

“The waste industry is, quite rightly, continually demanding more, and this shredder addresses that yearn for more flexibility, more uptime and more profits.”

More than 40 XRs are now in operation in some of the most innovative alternative fuel production plants worldwide.
