Energy consuming process
The main form in which sugar beet pulp is traded and fed to livestok is the dehydrated form. However, drying sugar beet pulp requirements are equivalent to 33% of the energy consumption of the sugar factory (Mujumdar, 2014). To this respect dried sugar beet pulp is less environment-friendly than wet and pressed sugar beet pulp.
Environmental care
Since the beginning of sugarbeet processing, sugarbeet pulp has been traditionnally fed to livestock in order to reduce the disposal of these sugar by-products that would otherwise rise environmental concern. This use is economically and environmentally valuable (ADEME, 2016). In places where there are no farm animals, other ways of using sugarbeet pulp had to be found. These include the use of beet pulp in ethanol production, solid biofuel or as a raw material for paper (Brachi et al., 2017; Yi Zheng et al., 2012; Vaccari et al., 2005).
