Sulzer innovations at SWANA 2017

This year’s SWANApalooza conference and exhibition opens in Reno, Nevada today March 27th. The four-day event will feature the 40th annual landfill gas and biogas symposium and 21st annual landfill symposium as well as technical sessions covering the prominent topics of the solid waste industry.

Sulzer will once again attend the SWANA Symposium and present a number of innovative solutions designed to improve the reliability and efficiency of engines powered by landfill gases.

Landfill gas is commonly used to fuel engines that power generators to produce electricity, but the variable methane content means this useful by-product needs to be carefully managed. Without precise control mechanisms, the efficiency of the combustion process may be compromised, which will have a knock-on effect on emissions.

2017 03 27 100021Sulzer has developed an innovative turnkey solution that can be used in conjunction with your existing engine control system to improve engine performance and reliability.

The latest solution from Sulzer uses advanced engine performance controllers, sensors and catalysts to create a bespoke package that can be installed alongside the existing engine controls, improving engine performance and reliability. Precision engine control is delivered by an advanced management system and combined with the latest catalysts to reduce emissions and improve efficiency.

Commercial forests are full of untapped energy

2017 03 20 110959

The theme of the 2017 United Nations International Day of Forests is Forests and Energy. The International Council of Forest and Paper Associations (ICFPA) is proud to represent the global forest products industry, which plays an important role in contributing to the production of renewable energy and reducing dependence on fossil fuels by using wood manufacturing residuals, byproducts and forest residues – collectively known as biomass – to produce much of the energy required for its operations.

The South African sector is represented through the Paper Manufacturers Association of South Africa (PAMSA). Jane Molony, PAMSA executive director and ICFPA vice chair, says that the local pulp and paper sector is in some instances totally self-sufficient and has additional power to sell into the grid. “This energy, by virtue of the cogeneration process and biomass based lignin content in black liquor, uses less water and emits less CO2 than regular coal based power production. This is why PAMSA finds it particularly galling that the Department of Energy’s recently published draft Integrated Resource Plan for energy excludes cogeneration as a viable, green technology.”

According to the international carbon accounting principle, when combusted for energy, biomass does not contribute to global climate change as growing trees sequester carbon from the atmosphere via photosynthesis. The ICFPA reiterates the carbon neutrality of biomass in a policy statement:

“The forest-based industry also can substitute for a wide range of fossil fuel-based products on the market, hence providing additional climate benefits as well as welfare to society,” said ICFPA President Elizabeth de Carvalhaes.

According to the United Nations Food and Agriculture Organization, wood provides the world with roughly 40 percent of current global renewable energy supply – more than solar, hydroelectric or wind power. Sustainably-managed forests have a key role in meeting several United Nations Sustainable Development Goals and providing solutions for a growing green economy.

To increase the role of forests in providing renewable energy and to reduce the use of fossil fuels, the forest-based industry invests in technological innovation and sustainably-managed forests to improve yields and practices. In the past ten years, the energy share of biomass and other renewable fuels has increased from 53 to 63 percent.

The ICFPA represents more than 30 national and regional forest and paper associations around the world. For more information about the sustainability of the global forest and paper industry, visit

Munich recycler on track to achieve 40,000 tonnes annual wood recycling target, with help of UNTHA

Munich-based recycling specialist Breitsamer Entsorgung is on track to process 40,000 tonnes of waste wood in 2017, following the successful installation of an UNTHA XR3000C mobil-e shredder.

The hunt for an efficient shredding solution began last year when the well-established 60 year old recycling business commenced its search for an electrically-driven machine. Breitsamer knew such a shredder would prove a more environmentally robust alternative to one with a traditional diesel engine, not least because the recycling specialists have their own 1.4 MW photovoltaic system installed on site. And, with 60% of this system’s energy generation powering the Breitsamer facility, this would prove a more economical solution too.

But an electric drive was not Breitsamer’s only requirement. The shredder would also need to process 35 tonnes of waste wood, per hour, and achieve a homogenous particle size of less than 120mm, in a single pass.

2017 03 08 155652

Conversations with UNTHA unfolded and managing director Thomas Breitsamer became impressed with the energy efficiency of the shredder as well as the machine’s mobility – two factors not found in competitor models.

Commenting on the innovative UNTHA Eco Drive concept within the XR mobil-e, Thomas said: “This UNTHA technology makes us 70% more economical than if we were using diesel power and 30% more economical than the conventional star-delta drive. The low speed nature of this shredding system also keeps the noise of our pellet production at a very low level, as well as producing a very low amount of fine particles.”

The movable nature of the XR3000C mobil-e means it can be repositioned around the site, which allows for easier and safer technician maintenance for instance, as it can be moved out of the hall. The shredder has been purposefully engineered for ease of maintenance to ensure minimal downtime and – with the ability to change perforated screens in less than 30 minutes – Breitsamer can quickly and easily recycle different wood grades, to different grain specifications.

Thomas elaborated: “We can now offer excellent recycling, not only in waste wood classes 1 to 3, but also in class 4 waste wood and can sell the metals recovered from it to the steel industry. This flexibility is important because we have several customers in the thermal and material recycling industry, who require granules in various sizes.”

Established in 1956, Breitsamer Entsorgung Recycling GmbH has repeatedly extended its Munich site over the years. With an approved annual waste processing and storage capacity of 205,000 tonnes, the business has largely focused on construction, commercial and industrial waste until recently. But in 2014 came the redesign of a dedicated waste wood processing plant.

Keen to ensure the right purchase, Breitsamer utilised the XR mobil-e over a rigorous test period. This enabled close collaboration with the UNTHA team, to ensure the best-fit – and unique – configuration that would fulfil the company’s requirements entirely.

The XR mobil-e was first unveiled by UNTHA in May 2016, at the world's leading trade fair for environmental technology, IFAT. The shredder has since been sold worldwide, due to its flexible capabilities when safely and efficiently handling a variety of applications including industrial and commercial waste, production waste, construction waste, and – as in the case of Breitsamer Entsorgung – waste wood.


Sparrows Group to supply 103 cranes for the East Anglia ONE offshore wind farm

Aberdeen-based Sparrows Group has signed a contract to supply 103 cranes for installation at ScottishPower Renewables’ 714 megawatt East Anglia ONE offshore wind farm.

Located off the coast of Suffolk, the wind farm will be capable of producing enough electricity to power around 500,000 homes and is anticipated to generate first power in 2019 and be fully-operational by 2020.

All the offshore wind turbine cranes will be designed and manufactured at Sparrows facilities in Aberdeen for Granada Material Handling on behalf of ScottishPower Renewables. A crane will be installed on each of the farm’s 102 wind turbines with a further crane used for training purposes.

2017 03 07 082507

The sizeable award marks Sparrows biggest ever renewables contract to date and firmly establishes their position as an engineering and services provider in the sector. The cranes which are part of the firm’s offshore wind specific WindMaster range are designed for use on offshore wind turbine platforms with 99% of their parts procured within the UK. Production is expected to start early 2017 with final delivery scheduled mid-2018.

Scotland’s First Minister Nicola Sturgeon said: "Sparrows is using expertise developed in the oil and gas sector and transferring it to other energy and manufacturing sectors. Securing this major contract is a significant milestone for the company, and demonstrates the opportunities that exist for the Scottish supply chain.

"In line with the Scottish Government’s draft Energy Strategy, my government will continue to support the recovery of North Sea oil and gas. We will seek to maximise the opportunities for production, exploration, and decommissioning but at the same time, encourage the industry to play a positive role in the low carbon transition."

Stewart Mitchell, chief executive officer of Sparrows, said: “East Anglia ONE is a large scale and high-profile wind farm that will deliver substantial benefits for the UK for many years to come. This contract award is recognition of the expertise that exists in the UK and we are working hard to ensure we play our part in cementing Aberdeen and the North East as a global skills hub and providing job security for our employees.

“We have utilised our extensive knowledge of operations and maintenance to design a range of highly reliable and low maintenance offshore wind turbine cranes that are ideal for the renewables sector.”

“Diversification into multiple sectors and industries is part of our long-term strategy in achieving our business growth aspirations nationally and internationally.”

Charlie Jordan, ScottishPower Renewables’ Project Director for East Anglia ONE, said: “It is positive to see that many highly-skilled jobs in Aberdeen and the West Midlands will be supported with the award of this contract. Granada and Sparrows have considerable experience in delivering cranes for the offshore environment, and we look forward to working with them.

“East Anglia ONE will deliver industry-leading levels of UK content, as well as being the best value offshore windfarm ever to go in to construction. We hope that further major contracts will be placed in the UK in the coming months, adding to the jobs and investment we are already creating in Great Yarmouth, Lowestoft, Hull, Belfast and Aberdeen.”

UNTHA’s largest four shaft shredder heads to LKM Recycling

UNTHA’s largest four shaft shredder has been installed at renowned waste management firm LKM Recycling.

The RS150 has been procured to maximise materials recovery and revenue generation at this increasingly diverse recycling specialist. Over 40 years ago, LKM started out as a scrap metal business but fast forward to 2017 and the 55-strong company is now handling everything from metals and glass, to wood, plastic and general waste.

This robust 22 tonne machine will therefore enable LKM to process an array of complex and often heavy duty applications including aluminium, tyres and uPVC windows. Set to achieve throughputs of up to 12 tonnes per hour, the RS150 and its quick-change screens will achieve flexible homogenous particle sizing as small as 30mm, depending on customer requirements.

2017 03 07 075707

It is also expected that LKM’s annual recycling volumes will increase by up to 25% in line with the team’s ability to now profitably process a wider range of materials.

Commenting on the investment, LKM’s managing director Tony Hughes said: “This is our first UNTHA machine – in fact it is the first processing machine we’ve ever bought. It will completely revolutionise our approach to recycling because we’ll soon be able to liberate all of the materials from the streams we process. By shredding and screening uPVC windows, for instance, we’ll be able to separate the ‘waste’ into its component parts with ease. This means more material going back into the industry for reprocessing, and more revenue yield for our business.

“The high torque, slow speed eco-drive concept within this machine will also keep power consumption low, which minimises our carbon footprint and saves on energy costs. You wouldn’t expect these efficiencies within such a heavy duty machine of this size.

2017 03 07 075728

“This sophisticated new low-noise operation now really sets us apart from competitors of our size.”

Having first begun the market research phase three years ago, the LKM team has since travelled to UNTHA’s Austrian headquarters to see the RS shredders in production and to trial the machine using an array of materials.

Tony continues: “We’ve been really impressed with the UNTHA set up. Of course the shredding technology is renowned, but there’s a real focus on the development of relationships too. I suppose that’s how they ensure clients get the greatest return from their assets long into the future.”
