Gypsum industry news
Japan: Chiyoda Ute is taking part in a demonstration project intended to demonstrate the recycling of gypsum wallboard. The so-called ‘horizontal recycling scheme’ includes construction company Mori Building, interior design company Senba and wallboard recycling company Tokuyama Chiyoda Gypsum. Based on the results of the demonstration the companies hope to build a wallboard recycling supply chain.
It is estimated that the volume of wallboard waste in Japan will exceed 2Mt/yr in 2032 and 3Mt/yr in 2047. However, there are concerns that the recycling rate is low and managed final disposal sites are becoming scarce. In addition, supplies of synthetic gypsum from coal-fired power stations are expected to decrease. At present the country imports over 2Mt/yr of gypsum.
Japan: Chiyoda Ute intends to launch a gypsum board product, Chiyoda Hokkaido Board, which uses 50% recycled gypsum, from December 2023. The product will be manufactured at its Muroran plant in Hokkaido. Subsidiary Tokuyama Chiyoda Gypsum opened a gypsum recycling plant in Muroran in September 2023. Chiyoda Ute owns a 49% share in Tokuyama Chiyoda Gypsum and Tokuyama Corporation owns the remainder.
