Environmental protection and economic efficiency in harmony
Customer: Wanhua (China)
The Chinese Wanhua Industrial Group is one of the world’s largest manufacturers of MDI glue. In 2006, the Group founded its subsidiary Wanhua Ecoboard, which works closely with Dieffenbacher to develop and produce sustainable, formaldehyde-free boards from wood and straw.
That’s how we helped Wanhua get ahead
Since 2015, when Wanhua Ecoboard signed the first supply contract for a straw-based particleboard plant, the company has relied on our expertise in alternative raw materials and the processing of annual plants and fast-growing woods. In October 2017, the first straw-based particleboard was produced in Chenzhou in the province of Hunan. That’s how we’re harmonizing environmental protection and economic efficiency for Wanhua.
The cooperation between Wanhua and Dieffenbacher already covered six straw-based particleboard lines when Wanhua expanded its production to include straw-based MDF, Fine OSB and Super PB with four additional lines between 2019 and 2021. In total, Wanhua now operates ten Dieffenbacher plants.
Wanhua's fine OSB plants use the MAIER 2-stage OSB technology, consisting of a MAIER OSB drum chipper and MAIER strand flakers, to produce strands from weak wood assortments.
“In today’s fast-paced world, such a long period of uninterrupted cooperation is quite rare. But Dieffenbacher, as one of our most important partners, has proven time and again the wisdom of our continuing to invest in this partnership. Committing to our ninth and tenth lines confirms the excellent quality of our collaboration.” Shouheng Zhang (General Manager of Wanhua Ecoboard) in December 2021
