CO2-neutral sugar factory, in affordable steps

Abstract

The first step for a sugar factory to become CO2 neutral is to replace the existing drum drier with a steam drier. The cost of this is approx. €250 per ton of CO2 reduction per year. In this first step, the CO2 emissions of the factory are reduced by approx. 33% The second step is to burn the steam-dried sugar beet pulp in the boiler, and the factory will be CO2 neutral, except for the lime kiln. There will be some excess sugar beet pulp, depending on the efficiency of the sugar factory.
