US: USG has blamed falling operating profits on costs relating to its ‘Customer-First’ strategy and rising general costs, including those from transportation. Its operating profit fell by 32% year-on-year to US$121m in the first half of 2018 from US$179m in the same period in 2017. Its net sales rose by 6% to US$1.67bn from US$1.58bn.

For its wallboard and surfaces business the company said that its wallboard price increased by 2% from the second quarter of 2017 due mostly to a price increase in January 2018. Wallboard sales volumes increased by 2% compared to the second quarter of 2017. However, wallboard costs were US$12m higher than the previous year primarily due to rising input and transportation costs.

The building materials producer confirmed that its merger with Germany’s Knauf is expected to complete in early 2019, subject to shareholder and regulatory approval.

US: A team from Washington State University have developed bricks made from recycled gypsum wallboard. The blocks are made from 80% drywall waste and a binder made from industrial by-products. They are waterproof and lighter than earth blocks, bricks or concrete blocks. The researchers are partnering with local contractors to get the waste, and architecture students are using a press to build the blocks, which look like masonry bricks.

The researchers, including Taiji Miyasaka, professor in the School of Design and Construction, David Drake, adjunct faculty in the School of Design and Construction, and Robert Richards, a professor in the School of Mechanical and Materials Engineering, began developing the wallboard blocks in 2017 with a grant from the American Institute of Architects. They have also received an Amazon Catalyst grant to move the project from laboratory scale to a demonstration structure. In the next year, the researchers will be testing the blocks to meet building, seismic and fire codes. They also aim to build a 15m² demonstration structure.

A prototype structure featuring the wallboard-based bricks will be displayed as part of the ‘Make/Do: A History of Creative Reuse’ exhibition that is running at the Washington State History Museum until December 2018.
