Insulation industry news from Global Insulation

China/Germany: German companies Evonik and ThyssenKrupp Industrial Solutions have granted a licence to Zibo Qixiang Tengda Chemical for the use of its hydrogen peroxide to propylene oxide (HPPO) technology in China. Qixiang Tengda Chemical will build a propylene oxide plant in Shandong province and Evonik has licensed the production of hydrogen peroxide for the exclusive supply of the plant. Evonik and ThyssenKrupp Industrial Solutions have also entered into a long-term agreement for the supply of the respective HPPO catalyst. Propylene oxide is used mainly for the production of polyurethane foams, including those used in insulation for buildings.

“We’re proud of having gained Qixiang as a new strategic partner. With environmental awareness on the rise in China, HPPO is the technology of choice for sustainable production of propylene oxide because it produces no major by-products apart from water,” said Claus Rettig, the chairman of the board of Evonik’s Resource Efficiency division.

Planning work for the new Qixiang Tengda plant is scheduled to start in mid-August 2019 with commissioning expected for the first half of 2022. Qixiang Tengda, a chemical manufacturer, is part of Cedar Holdings Group.

China: A study by researchers from Australia's Commonwealth Scientific and Industrial Research Organisation and Britain's University of Bristol says that the provinces of Shandong and Hebei are the source of a rise in trichlorofluoromethane (CFC-11) emissions. It attributed about 40% to 60%of in the rise in CFC-11 since 2013 to this region, according to Reuters. After studying atmospheric data from South Korea and Japan they estimated that CFC-11 emissions from eastern China during the 2014 - 2017 period were around 7000t/hr higher than 2008 - 2012.

Previously in mid-2018 an investigation by the Environmental Investigation Agency (EIA) speculated that the widespread use of CFC-11 by Chinese rigid polyurethane (PU) foam producers might be the source of the reported rise of emissions.

China launched an inspection campaign into 3000 foam manufacturers in 2018 and promised to punish any violations of the Montreal Protocol treaty. The Ministry of Ecology and Environment said in March 2019 that it had shut down two manufacturing areas that produced CFC-11. It added that its investigation into PU foam makers had not found any large-scale usage so far but that producers may be getting better at hiding their operations. It also noted that there was ‘uncertainty’ in published research and called for better detection mechanisms.

China: Luyang Energy-Saving Materials plans to spend US$11m towards upgrading its mineral wool insulation plant in the Yiyuan Economic Development Zone in Shandong. The upgrade will add 25,000t/yr production capacity to the plant, increasing its total output to 50,000t/yr, according to Reuters. Construction is scheduled to start in July 2017 with completion in June 2018.
