Resand Ltd.’s sand-reclamation process will make its U.S. debut at Acme Foundry in Coffeyville, KS, the company announced. The Finnish developer and the gray iron foundry have a framework agreement to cooperate on a thermal-mechanical sand-treatment installation to operate under a “service-based business model,” according to the announcement.
No schedule was announced for the Kansas installation.
Together, Acme Foundry and Resand “will develop a circular sand management solution for foundry operations …, supporting the transition from linear disposal practices toward circular raw-material management.”
The agreement also sets the terms for Resand’s first Sand as a Service (SaaS) agreement in the U.S., it stated, and supports future deployment of its treatment process in the U.S. market.
“By establishing Resand Ltd. and preparing our first SaaS agreement in North America, we are creating the foundation for long-term growth and demonstrating how circular sand management can deliver both environmental and economic value to American foundries,” stated Mikko Immonen, CEO.
The patented Resand process involves treating spent sand at up to 650 °C in the top of a two-chamber unit, burning off binder materials and organic chemicals. The thermally treated sand is mechanically “polished” and de-dusted to remove impurities, separating clean sand grains from waste material. This regenerated sand is cooled for immediate reuse in mold or coremaking.
Resand already operates several treatment units with SaaS agreements in place at foundries in Finland, Germany, Spain, and Sweden.
The process also treats sand from additive manufacturing operations, including a new order from ExOne for an electric reclamation unit to treat 3D-printing treated sand 3D printing at Gersthofen, Germany.
