In 2020, Zenviro Tech acquired the US division of the Eisenmann Environmental Technology business unit, including its key management and subject matter experts. For almost 70 years and with over 1000 environmental technology systems deployed, the Eisenmann name has been synonymous with excellence and customer satisfaction and our reputation has been built on strong trusting partnerships, industry leading expertise and world-class technology, innovation and service. Now we launch a new chapter, with a new owner and a new brand, Zenviro Tech. We will continue to focus on our core market segments, Industrials and Renewables, helping our customers solve their most complex environmental and compliance challenges. We will also be expanding our collaboration with strategic partners around the globe delivering more integrated solutions while we continue to expand our global footprint with offices in Chicago, Shanghai, Milan and Mexico City.

The Renewables business, formerly the Organics Diversion Group, will continue its focus on providing customers with organic waste to biogas solutions using anaerobic digestion technology for both dry and wet waste streams. But we will also be adding other renewable technologies to our portfolio through our strategic partnerships like the Integrated Biogas Alliance, as well as by acquisition. This is an exciting time to be in this sector and Zenviro Tech is well positioned with an impressive legacy of biogas plant references.
