Rapid innovation will generate IoT plat- forms and seamless technologies into new services and product offerings. The need for ongoing research and development will drive STEM (Science, Technology, Engineering, Mathematics) disciplines.Weneed toprepare for these complexities, so that the added layers of life cycles are anticipated in tomor- row’s briefs and an ‘egg-on-face’ situation is narrowly averted. We have to collaborate Circular solutionswill only realise sustainable, future-proofedecosystems if everybody is on board. Perhaps even more important than the engineers and designers, governance and regulation are crucial in endorsing these processes. Redesigning supply chains and business models require robust round-table discussions betweenbusinesses, universities, social groups and policymakers. Initiatives such as the Ellen MacArthur Foundation’sCircularEconomy100embraces this idea that closed-loopambitions cannever beachievedbyworkinginisolation.Thisgroup ties together supply chain leaders, industries and geographies. From designers to academ- ics, CEOs to city mayors, people are locking heads and sharing their complementary ex- pertise. The result ofwhich is amore effective and holistic solution that generates wins for both the planet and our pockets. Linear thinking can’tmeet theneeds of the emergingcirculareconomy.However,allisnot lost. Draw a straight line long enough and it would actually envelop the globe, paradoxi- callymaking a circle.What we need are linear thinkers to be open-minded to extrapolate their thinking out far enough in order to, ultimately, draw the same conclusion – that a circular approach is actually where all roads lead. Going forward, drawing circles around our consumer behaviourmay be the bestway to draw the line. q

N-series shear speeds-up metal recycling Texas-based metal recycling company, Oak Cliff Recycling, has selected Metso’s N-series inclined shear (NIS) to maximise metal processing efficiency. New housing design for Lindemann shredders

Metsohas developed a newhousing design that cuts service downtime, facilitates the maintenance of recycling equipment and makes it easier to keep the machinery in topshape. Available for almost everyMetso Lindemann TM shredder, the new solution enables multiple maintenance operations to be performed conveniently, swiftly and at one time. Themost significant improvement is the detachable front wall. The removable unit provides easier access to wear parts and speeds up the replacement ofworn compo- nents.The new design also enables several maintenance tasks to be carried out at the same time. With the detachable front wall lifted out of positionwith a crane, the rotor adjustment and the replacement of wear plates, for example, can be conveniently handled simultaneously. Minimising maintenance downtime in production is achievable by acquiring a secondMetso front wall set for stock. This makes it possible to replace thewhole front wall and its worn parts immediately, so that production can be restarted without delay. All the required maintenance for the dismantled set can then be done while production is up and running so that it is ready for the next service break. The solution is available as a retrofit for existing middle housings, as part of a com- plete new middle housing, or as standard for all newMetso Lindemann machines. q

“Metso’s NIS can process difficult ma- terials quickly and efficiently. Cutting cycle times are fast, and the design of themoving floor ingetting the scrapmetal to theblades removes the added time of folding and compressing in a box,” says Benjie Smith, owner, Oak Cliff Recycling. The Texan recycling company has struggled with unwieldy materials in con- ventional style shears that slow down pro- duction. Oversized and often intractable material hampered recyclingprocesses, but the challenges were detected and solved with the help of Metso experts. TheMetsoNIS is a state-of-the-art grav- ity feed shear that can accept longmaterial and large bulky scrap and is available with cutting forces from 600 to 1 250 t. Self- containedandeasy to install, theunit offers exceptional performance on heavy-melt scrap, auto bodies, steel mill scrap, miscel- laneous shapes, pipe, plate, shipbreaking, railcar, demolition scrap, aluminium, and stainless steel materials. Regardless of the size of business, big or small, the NIS is at the forefront of provid- ing the technology and services needed to ensure success. The N-series range is fully backed by Metso’s worldwide service net- work. Service contacts are locally available to customers so that they have efficient direct support when required.
