Gypsum industry news

Germany: Grenzebach has expanded its portfolio by acquiring the technology to build its own special hammer mill, previously sourced from Beumer Group subsidiary FAM Minerals & Mining. The hammer mill processes particle sizes of 0 – 50mm, with a throughput of up to 50t/hr. The acquisition also covers technology for the dynamic classifier. Grenzebach says that it will continue to further develop its portfolio of calcination line components, focused on energy efficiency, carbon reduction and digitisation.

CEO Robert Brier said “We are constantly looking for ways to optimise our customer orientation. That is why we were very interested in expanding our portfolio and ultimately acquired the technology.”

Spain: Bulk materials handling equipment supplier Bedeschi says that it has won a contract with fellow Italy-based company Fassa Bortolo to equip a planned gypsum stacking plant in Spain. The plant will homogenise gypsum for storage in an 8000m³ storage pit at a Fassa Bortolo quarry. Bedeschi says that the central part of the order is composed of a 300t/hr metallic apron feeder and stacker car, a 150t/hr excavator belt and a fully enclosed conveyor belt line. The supplier noted that it previously executed a ‘very similar’ order for Fassa Bortolo once before.

US: Saint-Gobain subsidiary CertainTeed's Buchanan gypsum wallboard plant in New York has successfully participated in a gypsum wallboard recycling pilot. Together with contractors Structure Tone and Cooper Recycling, it processed 20t of gypsum from waste wallboard in its gypsum wallboard production.

CertainTeed interior products vice president and general manager Jay Bachmann said "For us to achieve our sustainability goals, we must change the way we think. By partnering with organisations in the community like Cooper Recycling and Structure Tone, we can get there faster." Bachmann continued, "As the only gypsum manufacturing plant in New York, our colleagues in Buchanan were able to create a true circular economy. From the creation of drywall products to construction, to processing scraps and back into drywall production, the material is continuously used and never leaves the state. This maximises our company's positive impact while working to minimise our environmental footprint. Our Buchanan plant has increased our capacity to reuse recycled material, and we look forward to growing this successful pilot into a long-term programme, while working with builders and recyclers across the state. Partnering with CertainTeed, New York builders have the opportunity to not only reduce waste at their job sites, but also gain Leadership in Energy and Environmental Design (LEED) points on their projects."

The Buchanan plant joins CertainTeed's units at Nashville in Arkansas and Palatka in Florida in supporting the company's circular economic efforts in the US. The Nashville plant commissioned a 65,000t/yr line in May 2022, while the Palatka plant increased the recycled content of its wallboard by 18,000t/yr in August 2022. The Palatka plant plans to install a new 100t/hr Rotochopper grinding unit to replace its existing trommel machine in its reclaim processing and screening operations.

US: The US Department of Energy has awarded CertainTeed its 2022 Better Project Award for the company’s installation of a 15,000t/yr production scrap paper recycling system at its Silver Grove, Kentucky, gypsum wallboard plant. The plant recycles ground paper and gypsum from the system in its gypsum wallboard production.

CertainTeed vice president environmental, social and governance North America and Saint-Gobain circular economy solutions managing director Dennis Wilson said "Our recycling technology in Silver Grove allows us to reduce our waste, reduce our consumption of natural resources and also reduce our production costs - all while continuing to produce the best gypsum wallboard product on the market.” Wilson continued “We will continue to look for ways to minimise our environmental footprint while striving to maximise our company's positive impact for our customers and the communities where we operate."

US: ML Environmental Group has secured a strategic partnership and exclusive US distribution agreement with gypsum wallboard recycling technology producer Scott Equipment Company. Scott Equipment Company produces the GypStream paper backing removal system. Together, the companies say that they will expand the gypsum wallboard recycling solutions offering available to US customers.

Scott Equipment Company business development and product marketing manager Kevin Pedretti said "Our recycling systems, including both the food waste organics recovery system and the gypsum wallboard separation and recovery machines, position nicely with ML Environmental Group's vision to offer their customers an end-to-end solution.” He continued "We have been very impressed with the leadership and growth of ML Environmental and look forward to making the world a better place with this partnership."

US: Munson has launched a ribbon blender for the homogenisation of dry bulk solids, including gypsum plaster. The unit, which can also blend solids with liquids from its spray lines to pastes or slurries, has a volume of 2.4m³. The company reports that its novel bag dump, which draws dust into filter cartridges by intermittent blasts from a number of nozzles, will improve worker safety and plant hygiene.
