We have developed our conveyor range as the cost of using wheel loaders – such as the cost of diesel and oper- ators to control them – has become extortionate. Our new tracked conveyor facilitates a higher stockpile, reducing the use of a loader so it is more cost effective for our customers. It equates to less downtime and more efficiency throughout the processing operation, as the loader can be employed else- where. It also improves site safety, through the reduction of loader and haul truck movements. We also see huge potential in our EvoQuip range of compact crushers and screeners to meet end users who are working on smaller residential construction projects as well as plant and tool hire. Ten years ago there were just a couple of smaller players in the compact plant market. Now there are more and more contractors doing crushing and screening and we're pleased that we now have a range to cater for that market. Finally, we're very aware that our machines are huge investments for our customers, so have invested heavily in telematics – technology that pulls data from their machines in the field that helps them make informed decisions about their fleet. In addition to regular reports on machine and fuel consumption, output production tonnages, GPS machine tracking, operating hours – all to help customers manage their fleet (particularly useful for contractors and plant rental com- panies), our telematics is tied into predictive maintenance, where customers can know when their machine is due a ser- vice or when parts may need replaced. With telematics, we work with our customers to maximize uptime and longevity of their machines and can make sure that we can have the right parts, at the right place, at the right time. RP: President Trump promised $1 trillion in infrastruc- ture funding, but so far that has not materialized. How confident are you that we will see a solid plan in the coming year? What do you base your answer on? Hegarty: We've been a big supporter of the Association of Equipment Manufacturers' (AEM) efforts to pass a long-term infrastructure-spending bill because we believe it would be good for the industry. A well-funded long-term infrastructure bill will certainly help Terex Materials Processing as well as the other Terex segments, since most construction requires pro- cessed aggregate as a building block for concrete and asphalt. RP: A popular new book, and many national and interna- tional media reports, decry the dwindling supply of sand available to the construction market. Do you buy that? Do you have products or services designed to address a potential sand shortage? Hegarty: The dwindling supply of sand as a construction resource has been well documented in the media for many years. Our observations in many markets around the world lead us to believe it is a very real situation that has the poten- tial to become a crisis without the correct interventions and legislations being put in place. We study the published statistics on sand consumption to understand how the demand environment is driving the issue. We know that sand is the most extracted natural resource in the world, second only behind water, so we study reports to try and quantify the global appetite. An example is China, where between 2011 and 2013 they alone consumed more concrete (of which sand is the primary constituent) than the United States did through the whole of the 20th century. There are of course regional differences and some regions of the world are less effected. In Western Australia, there are still many deposits of high quality construction and industrial sands that require minimal processing. For most developed and developing regions across the globe however, the deple- tion of high quality reserves is very real and has driven efforts to establish new and innovative methods of producing con- struction grade sands and fine aggregates. Taking India as an example, historically most sand was dredged from rivers but in recent times, a government crackdown on the practice has led to a boom in manufactured sands where the sand is derived from crushed rock fines. In the UK and West- ern Europe, more and more construction, demolition and excavation waste material is being recycled into re-usable aggregates and sands through modern and innovative wet processing techniques. Terex Washing Systems have a complete product range that is capable of processing natural/virgin sands but also in pro- ducing manufactured and recycled sands and aggregates. We see these particular segments as significant growth opportu- nities and part of our product development roadmap is the advancement of technologies to accomplish higher recovery rates of raw materials from complex waste streams. When it comes to recycled aggregates and sands, one cur- rent impediment is around the acceptance of these products for use in high quality and structural grade concretes. We believe enhanced test criteria and the rapid development of applicable product standards are crucial in order to better define recycled aggregate characteristics and improve over- all acceptance. The growing shortages of natural sand in many regions around the world will continue to drive the latter and we believe Terex Washing Systems have a product range and expertise that will continue to develop innovative solutions that complement the efforts in producing high quality mate- rials from difficult waste streams in a cost-effective manner. RP: Have you noticed changes over the past year in the
