42 CEMENT AMERICAS • Fall 2018 • www.cementamericas.com FEATURE A number of stakeholder groups, beyond GCP's direct customers, have an interest in the social and environ- mental benefits of using Verifi. For example: • Architects are often enthusiastic about green design and sustainabil- ity. Through our new and growing Design Advantage service, GCP is interacting more frequently and collaborating more closely with architects in the North American market, and is communicating in a more integrated way about Special- ty Building Materials and Specialty Construction Chemicals products. This is an excellent opportunity to highlight the advantages of our new process-management technologies, including their substantial environ- mental benefits. • Municipal leaders (including may- ors, departments of transportation, and purchasing agents) are another important constituency. Many are leading climate change initiatives of their own, and may be able to encourage adoption of Verifi tech- nology – either through govern- ment purchasing or building codes – as part of their broader efforts to reduce greenhouse gas emissions. • Environmental advocates around the world, including the CDP (for- merly known as the Carbon Disclo- sure Project), the World Business Council for Sustainable Develop- ment (which has a Cement Sustain- ability Initiative), the United Nations Environmental Program, the Mas- sachusetts Institute of Technology (which has a Concrete Sustainability Hub), and many others. These orga- nizations may be willing, or even eager, to support GCP's efforts with their own time, energy, resources and reputations – if we can identify opportunities to collaborate. Examples and Data Example One: During 2013-2016, eight customers using Verifi technol- ogy showed a 10 percent reduction in the energy used for drum rotation, compared with pre-Verifi technology estimates based on the 2015 NRMCA survey. This represented 450,000 gal. of fuel savings, or about 4,000 metric tons of avoided CO2 emissions – equal to taking 856 passenger vehicles off the road. And at the prevailing price of $3/gal., it saved about $1,350,000 in fuel costs. Because these customers represent- ed only about 1 percent of the U.S. ready-mixed market (and a much smaller share of the global market), the potential impact through wide- spread adoption is much larger. Example Two: An average of 2,044 lb. of CO2 are emitted for every metric ton of portland cement produced in the United States. Using Verifi technology, a single customer was able to optimize two widely used mix designs, reduc- ing cement use by 2,722 metric tons in 2016 alone – the CO2 equivalent of taking 583 passenger vehicles off the road for a year – and providing a signifi- cant cost savings to the producer. Data: • Fuel efficiency – With an average number of high speed revolutions of 200 per load, early results indicate VERIFI technology can reduce high speed revolutions by 10 percent. This 10 percent reduction results in an estimated 3 liters of fuel saved per load. • Concrete waste reduction – With 350 million cu. yd. of concrete pro- duced in North America each year, a rejection rate of 5 percent means that 17.5 million cu. yd, are rejected annually – at a cost of around $175 million. Early results indicate that Verifi can reduce rejection rates roughly 1.2 percentage points. • Eco-efficient mix design – An aver- age mix design contains roughly 550 lb. of cement; if a conservative esti- mate of overdesign is 5 percent that would be 25 lb. of cement per cu. yd. – or 250 lb. per truckload. Matthew Nazarenko is the global mar- keting manager for the Verifi technol- ogy platform at GCP Applied Technol- ogies. Nazarenko is responsible for the development and execution of the glob- al Verifi business expansion program. He leads the multi-generation product development process, working with a cross-functional team and closely col- laborating with customers. He holds a Bachelors of Science degree in mechan- ical engineering from Union College, and an MBA from Rensselaer Polytech- nic Institute. He has been with GCP, for- merly W.R. Grace, for 12 years in vari- ous customer-facing roles. For the past five years he has been one of the lead- ers for the Verifi technology segment.
