How Novozymes reduces its CO2 emissions and energy consumption

At Novozymes we have set ambitious targets for our energy efficiency and CO2 emissions.

There is an increasing commitment to reduce CO2 emissions, stimulated by regulation and retailers’ more stringent requirements, and it is a priority for Novozymes to position our enzyme technology as part of the solution to address climate change.

Our long term targets to reduce energy consumption and CO2 emissions:

  • To improve energy efficiency by 50% in 2015 compared to 2005
  • To improve our CO2 efficiency by 50% in 2015 compared to 2005
  • To increase the energy supply from renewable and CO2-neutral sources to 50% in 2020
  • To improve energy efficiency by 50% in 2015 compared to 2005

Our short-term target for 2013 was:

  • To improve energy efficiency by 42% in 2012 compared to 2005
  • To improve CO2 efficiency by 50% in 2012 compared to 2005

In 2013 we reached the following numbers regarding efficiency improvements compared to 2005:

  • CO2 : 54%
  • Energy : 40%

Despite the successful implementation of all planned energy-saving projects, we were unable to meet the target, primarily as a result of lower global capacity utilization following the inclusion of the American site in Blair, Nebraska, in global supply operations.

One way of achieving this is energy savings in production. We are continuously and systematically searching for energy-saving projects, and an energy master plan has been established for each of our plants. Many savings projects have already been rolled out in our business worldwide. The other major area consists of activities that optimize our energy supply – either by producing or optimizing our own energy supply or by purchasing more CO2-neutral energy. See examples below on how we reduce CO2 emissions in Novozymes.

Investing in the world’s largest wind farm

Novozymes is also focused on minimizing CO2 emissions from our own production. We are working to increase the energy supply from renewable and CO2-neutral sources to 50% in 2020 across Novozymes. One example is our investment in the world’s largest wind farm, Horns Rev II, which in 2013 covered 100% of our electricity consumption in Denmark.

Novozymes and the Danish energy company DONG Energy entered into partnership in 2008 and have made possible the world's biggest offshore wind farm Horns Rev II and increased the production of electricity in Denmark based on wind power. Novozymes’ goal is to invest in electricity from Horns Rev II corresponding to our electricity consumption in Denmark by 2013. That will constitute just over 30% of the total production of electricity from the wind farm.

Producing biogas in wastewater treatment 

In China we are now producing biogas in our wastewater treatment. We have added an extra step to produce this biogas, which can be transformed into energy for use elsewhere in the production process. There are several possibilities for utilization of the biogas and transforming wastewater into energy will in time be rolled out globally to our other plants in the world. Many other projects have already been implemented such as recovery of heat from production. In the US we have replaced the burner in the steam boiler with a more efficient, automated model that saves energy. 


Climate potential influences pipeline

All pipeline discovery and development projects in Novozymes R&D must pass through a 'mini life cycle assessment' - known as a ‘pipeline LCA’. In this way the CO2 emission reduction potential of new products becomes part of the Novozymes’ R&D pipe-line decision process.
