Figure 2 shows the results obtained for both scenarios. The results for scenario 1 are split
according the three steps of the process: sugar beet production, sugar production and LA production.
All the environmental indicators show the environmental benefit of the chemical recycling process
(Figure 2). The post-consumer waste from the first life (virgin product) does not bear any
environmental burden when it is used as the feedstock in the second life.
In scenario 1, the agricultural phase plays a significant role for different environmental impacts,
amongst them POCP, AP and GER (the feedstock of the biomass is evaluated as an environmental
burden). The LA fermentation phase (from sugar to lactic acid) shows the highest impact forODP and
EP indicators, while the extraction of the sugar from sugar beet is significant for the Global Warming
Potential.
