“GoGreen”

Working for the climate

With regard to energy consumption and CO emissions, Nordzucker is already setting standards today and exceeding legal requirements. Since 1990, the energy consumed by extracting sugar from beet has fallen by 40 per cent, while CO emissions have decreased by 60 per cent.

We have set ourselves ambitious goals: Phasing out coal by 2030 and CO₂ neutrality by 2050 at the latest. Our employees in the “GoGreen” project are ensuring that all production sites are converted to climate-neutral production.

In a first step, we have examined the potential of different technologies in the field of renewable energies and evaluated their possible application in our factories. As a second step, we will now adapt the selected technologies to the local conditions in the factories. Which renewable energies are available in the local environment of a factory? What special challenges arise on site?

The project phase, in which we test the most promising technologies live on site in production, is particularly exciting.

Highly efficient energy use

In addition to introducing new technologies and switching to renewable energies, we are constantly working to reduce energy consumption. Because even renewable energies are not available to our world in unlimited quantities.

We need heat and electricity, and thus energy, to evaporate the approximately 75 per cent water from the sugar beet and to crystallise the sugar. Our boilers for generating steam are mainly gas-fired. The steam generates electricity via a turbine and is then used several times in the evaporation and cooking process to heat thin and thick juice. This combined heat and power system used in our sugar factories is particularly efficient. At 85 per cent, the efficiency of energy utilisation is significantly better than in conventional power plants (maximum 50 per cent).

Fact
Box
The extraction and crystallization of sugar takes place in many individual steps. A look behind the scenes provides clarification and is exciting at the same time.
