Lignin shortage threatens concrete admixture market

LignoTech USA, a supplier of lignin-based products to the concrete admixture industry, warns of a “critical supply imbalance” that will affect concrete admixture suppliers in north America.

“This condition is expected to continue for the remainder of 2015 and requires LignoTech USA to implement an allocation plan in order to support its existing customer base,” the company said in a ststementLignin is a key raw material in many concrete admixture products, including water reducers, retarders and mid-range water reducers.  

“The supply imbalance can be attributed to a shortage of seasoned pulp wood coupled with unexpectedly high demand the first half of the year and a series of unexpected operational interruptions.”

“We will continue to seek all available avenues to improve the situation,” said Attilio Caruso, chief executive, LignoTech USA.

“Our goals are to ensure a reasonable level of supply to all customers, minimize supply interruptions, reduce lead times and restore supply/demand balance.

“To this end, we have accessed our overseas supply base and will have significant additional volume available to supplement our capacity for the north American construction market. “

This additional supply will place us in a positive supply situation before the end of 2015.”

LignoTech plans to open a new plant in Florida in 2017 which is expected to double the supply of domestically manufactured lignosulfonates.
