What We Do
Novozymes has combined with Chr. Hansen to become Novonesis: linkedin.com/company/novonesis. This global biosolutions company of 10,000 people is transforming how the world produces, consumes and lives. In 30-plus industries, its biosolutions help businesses meet their needs and the needs of our planet. Novozymes was formed in 2000 when Novo Nordisk split into three companies: Novo Nordisk A/S, Novozymes A/S and Novo A/S. Novozymes was the world leader in biological solutions with a commitment to Rethink Tomorrow. It served 130 markets with enzymatic, microbial and advanced protein solutions. The company’s solutions enabled higher agricultural yields, low-temperature washing, energy-efficient production, renewable fuel and many other benefits. In December 2022, Novozymes and Chr. Hansen entered into an agreement to create a leading global biosolutions partner by combining the two companies. The goal was to unleash the full potential of biosolutions and generate significant value for all stakeholders and society. The combination was completed on January 29, 2024 and Novonesis was born. The name means ‘a new beginning’ and is derived from the Greek word ‘genesis’. It reflects a new era where we’ll better our world with biology.
