“…This demonstrates that the reliance on non-renewable P sources for production of P fertilizers directly contradicts both the principles of sustainable development and the principle of care in organic farming (IFOAM 2017). Furthermore, phosphate rock sources are increasingly polluted with cadmium (Cd), thallium and the radioactive elements uranium and thorium (Egle et al 2016). Therefore, we need a more efficient and sustainable P recycling within our societies.…”

The pollutant input and the risk of contamination by long-term application of recycled P fertilizers (RPFs) in European agricultural soils were estimated by a mass balance approach. Calculations based on literature data were carried out for the potentially toxic elements (PTEs) Cd, Cr, Cu, Ni, Pb, Zn and for the persistent organic pollutants (POPs) PCBs, PAHs and polychlorinated dibenzo-dioxins and -furans. The PTE accumulation estimation during 200 years of fertilizer application, equivalent to 11 kg P ha -1 year -1 , the mean P export via harvested products on European stockless organic farms, regarded soil background concentrations and proposed threshold concentrations. For PTEs, inputs were fertilizer application, atmospheric deposition and liming, output processes were leaching and crop harvest. The effect of varying site conditions was assessed by considering two precipitation excess (F) values and two soil pH values. For POPs, fertilizer application and the half-life time were considered. The PTE accumulation risk was low for most RPFs. For the analysed POPs no accumulation was found. The highest accumulation was found for all PTEs at pH 7 and F = 0.1 m year -1 , the lowest at pH 5 and F = 0.3 m year -1 . A high P concentration in fertilizers resulted in a low PTE flow per unit of P. Composts had the highest PTE accumulation risk due to lowest P contents. Struvite, meat and bone meal, digestate of catering waste, ash and biosolids would be better suited as P fertilizers. The use of fertilizers should be regulated based on their pollutant-to-nutrient ratio.

“…The calculation principle is illustrated in Figure 2. The energy input needed to prepare the sludge (2) and 3for incineration is subtracted from the energy output (4) of burning the sludge. A positive result (5) of this equation shows an energy potential, and a negative result (5) shows an energy expenditure.…”

“…In many countries across the world, discussions on the future perspectives of sewage sludge disposal have recently been gaining momentum [1]. In this context, the recovery of phosphorous is a key driver [2]. With a paradigm shift from end-of-pipe approaches (pollution removal) to resource-oriented approaches [3], wastewater treatment plants (WWTPs) generally tend to get seen as resource recovery facilities [4], including both phosphorous (P) recovery and energy provision [5,6].…”

The mono-incineration of sewage sludge offers new opportunities to develop wastewater infrastructure as regional energy cells and resource recovery sites. At the moment, the most important products of this technology are electric energy and heat from combined heat and power plants, as well as ash for the recovery of phosphorus. With spatial analysis, scenarios of the decentralized and centralized spatial organization of mono-incineration are assessed with regard to the energy balances of the incineration process, transport demands, and the possibility to accommodate excess heat in the surrounding spatial fabric, and these are evaluated by applying a multi-criteria analysis. The study is based on the Austrian case and shows that the utilization, not only of phosphorus and excess energy but also of other potential resources should be aimed for. The transport of sludge and the potential to use excess heat in the surrounding spatial fabric decide if centralized or decentralized scenarios are environmentally more feasible, whereas an “economy of scale” clearly gives leeway to the centralized options. Therefore, this study clearly demonstrates that introducing mono-incineration should not only focus on the process engineering itself but should also consider spatial planning provisions to reduce transport demands and to deliver excess energy to the surrounding spatial fabric.

Zusammenfassung Die Co-Vergärung getrennt gesammelter Bioabfälle gemeinsam mit kommunalen Klärschlämmen führt zu einer Unterbrechung des Nährstoffkreislaufs, wenn Klärschlämme nicht mehr als Dünger verwendet und zukünftig sogar verbrannt werden müssen. In diesem Artikel wird der Ansatz beschrieben, die im Restabfall enthaltenen biogenen Reststoffe als Substitut für derzeit eingesetzte Co-Substrate zu nutzen. Dazu wurden Restabfälle in einer 1. Phase charakterisiert und darauf aufbauend in einer 2. Phase mechanisch aufbereitet, um die Abtrennung eines möglichst störstofffreien Co-Substrats zu erzielen. Enthielt der untersuchte Restabfall aus Tirol knapp 20 % an Organik, lag dieser Wert in der Fraktion <40 mm bereits bei 47 % und in der Fraktion <10 mm sogar bei 67 %. Nach der Aufbereitung konnten Substrate mit bis zu 80 % an organischer Trockensubstanz und einem Biogaspotenzial von ca. 760 m 3 pro Mg organischer Trockensubstanz erzeugt werden. Eine großtechnische Umsetzung wird derzeit in einer 3. Phase vorbereitet, um Schwankungen des heterogenen Restabfalls ausgleichen zu können.
