26 • July 2015 www.concreteproducts.com Rayonier Advanced Materials, Jacksonville, Fla., and Borregaard ASA, Sarpsborg, Norway, have effected a letter of intent to develop a 150,000-metric-ton capacity production line for lignin, a cellulose-derived raw material where global supply and demand imbalance invites price spikes of products including con- crete admixtures. Their 45/55 joint venture will be based at the Fernandina Beach, Fla., cellulose fiber processing plant of minority partner Rayonier. Majority partner Borregaard cites world leadership in lignin-based products used for concrete plasticizers and superplasticizers, and operates New Jersey, Texas and Wis- consin sites under LignoTech USA Inc. The Fernandina Beach production line would increase overall LignoTech product capacity 30 percent, and represents what Borregaard CEO Per Sørlie calls "an excellent growth op- portunity for our lignin business in a global market which for some time has been supply constrained." "This partnership between the world's leader in cellulose specialties and the glob- al leader in lignin-based products is signif- icant for both companies," adds Rayonier CEO Paul Boynton. "[It] advances our strat- egy of leveraging the value of our assets and co-products while further enhancing the competitive position of our Fernandina Beach plant." A natural component of wood and co-product of cellulose specialties manu- facturing, lignin is currently used at the northern Florida operation for its energy val- ue. The Borregaard-Rayonier venture would process the dispersing agent into higher value, environmentally friendly alternatives to petroleum-based chemicals used globally in construction and industrial applications. Offcials anticipate an aggregate capital in- vestment of $110 million over fve years and two phases, the frst expected to commence operation in 2017. Realization of the JV is subject to board approvals and conclusion of defnitive agreements, plus fnal engi- neering, refnement of capital estimates, and obtaining required permits and related clearances. NEWS SCOPE READY MIXED LignoTech-backed $110M venture to stabilize global supply of key water reducer ingredient Build out of the lignin production at the Rayonier plant is projected over fve years.

In contrast to the predecessor ver- sion, National Ready Mixed Concrete Associ- ation Engineering staff notes, ASTM C94-15 places the onus on the customer to communi- cate all requirements for concrete from a proj- ect specification; sets mix air content at lev- els for moderate and severe exposure; directs the purchaser, when ordering ready mixed, to either state the required air content or indicate finished concrete exposure type; requires pur- chaser to indicate density when ordering heavy weight mixes, and clarifies terms for ordering lightweight aggregate by stating equilibri- um density; and, contains appendix revisions advising on strength overdesign concepts. A proposal to permit use of electronic tickets was balloted, but remains subject to resolution. In near-term balloting and meet- ings, Subcommittee C09-40 will revisit such issues as eliminating time limits to delivery; a performance-based option and scheduling when ordering concrete; and, defining batch water with consideration for water held back for addition at the jobsite. Development of a new specification for returned-concrete reuse is progressing.
