Die traditionell vielschichtige Abfallwirtschaft entwickelt sich mit der ihr eigenen Dynamik zur Kreislauf- und Rohstoffwirtschaft. Im vorliegenden Handbuch werden erstmalig alle wesentlichen Aspekte dieses Wirtschaftssektors – fachübergreifend und interdisziplinär – behandelt. Neben den in der Ressourcenwirtschaft relevanten rechtlichen Fragestellungen (u. a. Stoffrecht, Verwaltungsrecht, Haftung und Transport) sind die unterschiedlichen Stoffströme dargestellt (z. B. Glas, Papier, Verpackung, Metalle und Elektronik-Altgeräte, Bioabfälle) sowie Anlagentechnik und Logistik beschrieben (Abfallwirtschaftssysteme, Abfallbehandlung, Deponierung). Bei der Auswahl der Themen und Autoren lag der Schwerpunkt auf Praxisrelevanz und Praxisbezug.

Phosphorus (P) recovery through struvite is already both technically and economically feasible. This has been proved by more than 40 large-scale plants worldwide. However, when designing and implementing these P-recovery technologies, the environmental effects need to be considered. Therefore, a comparative environmental life cycle assessment of phosphorus recovery with different generations of the AirPrex® reactors at WWTP Wassmannsdorf and Amsterdam West was carried out in this study. Results show that both AirPrex® configurations with 1 reactor and 3 reactor have positive energy benefits and better environmental credits for the global warming potential (GWP), freshwater eutrophication potential, and marine eutrophication potential. The 3-reactor configuration shows better results in cumulative energy demand with 35% improvement of energy surplus, 36% reduction of GWP and less eutrophication potential. These improvements are mainly due to optimized struvite precipitation and harvesting and show that technology can be developed further, especially in plant operation and not only in the laboratory or pilot plant.

Phosphorus (P) is a limited resource, which can neither be synthesized nor substituted in its essential functions as nutrient. Currently explored and economically feasible global reserves may be depleted within generations. China is the largest phosphate fertilizer producing and consuming country in the world. China's municipal wastewater contains up to 293,163 Mg year of phosphorus, which equals approximately 5.5% of the chemical fertilizer phosphorus consumed in China. Phosphorus in wastewater can be seen not only as a source of pollution to be reduced, but also as a limited resource to be recovered. Based upon existing phosphorus-recovery technologies and the current wastewater infrastructure in China, three options for phosphorus recovery from sewage sludge, sludge ash and the fertilizer industry were analyzed according to the specific conditions in China.

Im Rahmen der EIP Water Action Group ARREAU fand am 16. Juni 2016 auf der Kläranlage Amersfoort (NL) das Kick-off der „Struvite Recovery & Recycling Learning Alliance“ statt, welche durch das Kompetenzzentrum Wasser Berlin gGmbH initiiert und organisiert wurde. Der Ort Amersfoort wurde gezielt gewählt, da hier die weltweit erste Kombination der Verfahren WASSTRIP, LYSOTHERM und PEARL in diesem Jahr im Großmaßstab in Betrieb ging.
