Prof. Wagner gave the first speech with the title of “SEMIZENTRAL: A new infrastructure concept for fast growing urban areas”. The challenges of water industrial infrastructure construction were presented first, and the concept of Resource Recovery Center (RRC) in the way of SEMIZENTRAL was introduced. Implementation of the RRC concept was successfully carried out in Qingdao, China, which was one of application cases in his study. Dr. Liao’ s presentation was “CAMBI advanced digestion for sludge management”. The theme was elaborated firstly with goals for biosolids management and low carbon biosolids management. Several key elements of advanced digestion with thermal hydrolysis technology and specific implementation status were emphatically demonstrated. Finally, application cases which were implemented by Thames Water and Beijing Drainage Group were introduced. Dr. Pang who is one of the early career editorial board members of the “Results of Engineering” presented the fundamental state of the journal and the contribution invited for the special issue of “Biomass waste to energy and resource”.
