GHG equivalent of waste treatment options, and
nutrient loss. Finally, the social indicators assessed were awareness
and image, compliance with the waste management hierarchy
(WMH) and social impact (local job creation). These values were
quantified and converted to values of 0 to 1 and illustrated in a
radar chart (Fig. 6). The value 0 is given for the best option and 1 for
the worst performance in terms of the given indicator. Therefore,
the larger the area of the radar, the worse the overall sustainability
of the scenario is.
