In Europa wird das Aufkommen an organischen Siedlungsabfällen im Jahr 2020 voraussichtlich 96 Mio. Tonnen erreichen. Seine Bewirtschaftung ist eine Herausforderung. Effiziente Prozesse sind wichtig, um höherwertige Produkte zu erzeugen. DECISIVE untersucht die dezentrale Bewirtschaftung in Lyon, Dolina, Barcelona und in Lübeck mit Schwerpunkt auf der anaeroben Vergärung in Verbindung mit Biogas und Gärrestnutzung. Dezentrale Ansätze sind vorteilhaft, z. B. im Hinblick auf einen geringeren Sammelaufwand, höhere Flexibilität, Systemresistenz, Bürgerbeteiligung und lokale Beschäftigung.
This report gives a business outlook on the implementation of the DECISIVE technical concept with the case study of Lübeck, Germany. The concept implementation is sub-divided into three scenarios which include building blocks from household food waste sorting over collection until treatment. The three scenarios comprise the following sub-concepts: 1. Sub-concept 1: Simplified food waste separation for residents 2. Sub-concept 2: Proximity food waste collection by alternative transportation means 3. Sub-concept 3: Food waste treatment by micro-anaerobic digestion technology While scenario 1 is only the implementation of sub-concept 1, scenario two comprises sub-concept 1 and sub-concept 2 and scenario 3 comprises all sub-concepts. The deliverable begins with a definition of the case study including the drivers, limitations and potential success factors for a transition towards decentralised elements in biowaste management. It continues with a detailed description of each sub-concept including its specific goals and a description of current related issues that are aimed at being solved by the respective concept. The following stakeholder analysis includes a description of the main ones to be involved in each sub-concept and their business opportunities. Furthermore, their influence on each sub-concept is analysed by means of a power-interest grid. PESTLE and SWOT analysis were conducted to determine external and internal factors influencing the business concept. The market analysis identified potential markets, its competitors and customers. With regard to the previous analysis, the implementation strategy was described following. First, a business model canvas gives an overview of the key elements of the overall business model. A description of the chosen scenarios for which the business model was developed is presented in order to describe the following financial indicators, which is the core of the business model. The financial indicators include a description of such, the overall costing of each scenario and the results for the chosen financial indicators. The overall costing is based on CAPEX, OPEX, revenues and additional funding necessary to run the concept economically viable. The financial indicators are net present value, return on investment and payback time. It was concluded that scenario one and two can be economically viable a short time after their implementation. However, scenario 2 needs some compensation since the revenue stream of waste fees reduced due to better sorting by inhabitants. It was generally assumed that the waste fee system remains as usual. Scenario 3 can be economically viable in the last quarter of its project lifetime. However, besides the compensation for decreased waste fees, additional funding would be necessary to achieve this net benefit. It was found that, in addition to the financial revenue generated in the case study described, external financial benefits can also be achieved if the scenarios are used as an educational tool to promote better sorting throughout the region. Furthermore, a strong social and environmental impact, which so far can only be monetised indirectly, is an important aspect for the implementation of the whole DECISIVE concept.
Die "Untersuchung der Bioabfall-Einsammlungssysteme mit Bewertung hinsichtlich dezentralisierter Systeme" beinhaltet drei Teile: Die Identifizierung wichtiger Faktoren für die Bioabfall-Einsammlung, die Untersuchung aktueller Bioabfalleinsammlung in den sechs DECISIVE EU-Ländern sowie der Darstellung einer Struktur für Bioabfalleinsammelketten, welche zu einer dezentralisierten Aufwertung beitragen. Der Fokus dieser Studie lag bei Lebensmittelabfällen von Haushalten und dem Lebensmitteldienstleistungssektor. Das Potenzial des Bioabfalls beider Ursprünge ist noch längst nicht ausgeschöpft und ist demnach an den meisten Orten theoretisch verfügbar und somit als Substrat für dezentralisierte micro-scale Fermenter, welche die Kerneinheit zur Valorisierung im Projekt DECISIVE bilden. ; This "survey on biowaste collection systems with evaluations for decentralised systems" consist of three parts: the identification of factors important for biowaste collection, the evaluation of the current biowaste collection in the six DECISIVE EU-countries, and the provision of a framework on biowaste collection chains for decentralised valorisations. The focus of the study was set on food waste from households and catering. The potential of the biowaste from both origins is currently not fully exploited, theoretically available in most locations, and suitable as feedstock for the decentralised micro-scale anaerobic digestion facilities, which are the core valorisation unit within DECISIVE. ; European Union
This study focuses on the collection and characterisation of bio-waste and in particular food waste (FW) as the core-substrate of DECISIVE. These issues are investigated in a case-study performed at the eco-settlement Lübeck-Flintenbreite (LF), which is part of the City of Lübeck (LC). Within the study, the locations are characterised, whereby LF specifically includes explanations on the settlement structures and LC focuses on the current applied collection and treatment procedures for bio-waste including source-separated bio-waste from biobins and non-separated bio-waste from residual waste bins. A waste composition analysis was carried out for wastes from bio-waste bins and residual waste bins comparing waste qualities. A special focus was placed on FW, which was distinguished into ten different fractions. Furthermore, an inventory of the technical infrastructure from LF was carried out. In LF a complete mAD system is available. It was constructed in an earlier project, but is yet to be operated. Specifically, the interface between source-separated bio-waste collection and mAD was investigated: the available decentralised shredder was operated with various source-separated bio-waste samples. Finally, scenarios for the transition of LF towards decentralised bio-waste management and the usability of the available mAD process units were evaluated.
