VANCOUVER: Lignol Energy Corp. and HA International LLC, a global producer of foundry resins, have successfully completed production trials of a lignin-based formula that eliminates the use of petrochemicals.

HA International and Vancouver-based Lignol, a developer of biofuels and renewable chemicals, used a formulation made from biomass containing Lignol’s High Performance Lignin (HP-L) for the production of a foundry resin used to cure sand into a mold that creates a shape from molten metal.

Lignol’s modified, solvent-based pre-treatment technology converts cellulose from biomass to ethanol, which produces the high-purity lignins.

The two companies report trials were conducted in the production of metal castings for ferrous and non-ferrous impellors used in a variety of pumping applications. They said the trial results met or exceeded the unidentified customer’s performance requirements and reduced smoke and odour during the pouring of the molten metal.

“Displacing petrochemicals in our resin formulation with HP-L can ultimately lead to providing our customers with greater price stability and better environmental performance,” said Doug Trinowski, vice-president R&D and quality at HA International.

The companies are now negotiating a supply agreement to continue shipping the new resin formulation to HA International’s customer. The foundry resin producer based in Westmont, Ill., will also look at incorporating HP-L in its other formulations.
