Other indicators


Acidification


From the table below, it is evident that, for those studies that present results on acidification, recycling is better
than incineration, which is better than landfill.

Studies n° 2,  4  and  5  do not include this indicator

Photochemical oxidation


According to the existing results, landfill appears to be the worst option, while recycling has a minor advantage
compared to incineration

Eutrophication


Unfortunately, only one study includes eutrophication in the impact categories. In this study, for both materials
analysed, landfill seems to be the best option.

Human Toxicity


With one exception, recycling is classified as the best option, while landfill is the worst in terms of human toxicity.
