The importance of resource recovery for environmental sustainability of an energy self-sufficient sewage treatment plant

Abstract
We have applied a state-of-the-art env. sustainability assessment to an energy positive sewage treatment plant, its supply chain and resource recovery: electricity production out of biogas from sludge digestion and the associated stabilized digestate, applied as agricultural fertilizer, production. Prominent aspects of our study are: a holistic environmental impact assessment, measurement of greenhouse gas emissions (including N2O), and accounting for infrastructure, toxicity of metals present in the digestate and replacement of conventional fertilizers and electricity. The impact of latter products is prevented. Overall, the system leads to a prevention of resource extraction from nature and a potential prevention of ecosystem diversity loss (though for some impact categories this cannot be quantified) but it also leads to a damaging effect on human health, mainly via climate change (dominated by N2O) and heavy metal (mainly Zn) toxicity of digestate. Resource recovery plays a crucial role in the environmental sustainability though the assessment methodology needs improvement.
