Regionalizing the Infrastructure Turn: A Research Agenda

An interdisciplinary ‘infrastructure turn’ has emerged over the past 20 years that disputes the concept of urban infrastructure as a staid or neutral set of physical artefacts. Responding to the increased conceptual, geographical and political importance of infrastructure – and endemic issues of access, expertise and governance that the varied provision of infrastructures can cause – this intervention asserts the significance of applying a regional perspective to the infrastructure turn. This paper forwards a critical research agenda for the study of ‘infrastructural regionalisms’ to interrogate: (1) how we study and produce knowledge about infrastructure; (2) how infrastructure is governed across or constrained by jurisdictional boundaries; (3) who drives the construction of regional infrastructural imaginaries; and (4) how individuals and communities differentially experience regional space through infrastructure. Analysing regions through infrastructure provides a novel perspective on the regional question and consequently offers a framework to understand better the implications of the current infrastructure moment for regional spaces worldwide

The Power of Standardisation - Innovationen durch Normen und Standards sichern und erfolgreich am Markt etablieren: 9. Mai 2017, Leipzig

Am 09. Mai 2017 luden das DBFZ Deutsches Biomasseforschungszentrum, die HHL Leipzig Graduate School of Management und die Universität Leipzig in Kooperation mit der Programmbegleitung des BMWi-Förderprogramms „Energetische Biomassenutzung“ zu einer Informationsveranstaltung und anschließendem Workshop zum Thema Standardisierung und Normierung ein. Anhand der beiden Keynotes „Start-ups sichern ihren Erfolg mit Normen und Standards' sowie 'Bedeutung und Anwendung von Normen, Spezifikationen und Standards“ wurde deutlich, dass das Thema sowohl für Unternehmen als auch für Ausgründungen aus der Wissenschaft und den Forschungstransfer zunehmend an Bedeutung gewinnt. Allerdings sind die Vorteile und Kombinationsmöglichkeiten der Normierungs- und Standardisierungsverfahren noch nicht bei allen Akteuren gleichermaßen bekannt. Hier konnte die Veranstaltung durch die Vorstellung von ausgesuchten Förderprogrammen, Normierungsverfahren und Best-Practice-Beispielen ansetzen sowie Fragen und Herausforderungen im Workshop diskutieren. Der vorliegende Band bietet Ihnen die Möglichkeit, die Vorträge und Abstracts noch einmal nachzuvollziehen

Extraction and Characterization of Biogenic Silica Obtained from Selected Agro-Waste in Africa

Increased amounts of available biomass residues from agricultural food production are present widely around the globe. These biomass residues can find essential applications as bioenergy feedstock and precursors to produce value-added materials. This study assessed the production of biogenic silica (SiO2) from different biomass residues in Africa, including cornhusk, corncob, yam peelings, cassava peelings and coconut husks. Two processes were performed to synthesize the biogenic silica. First, the biomass fuels were chemically pre-treated with 1 and 5% w/v citric acid solutions. In the second stage, combustion at 600 °C for 2 h in a muffle oven was applied. The characterization of the untreated biomasses was conducted using Inductively coupled plasma—optical emission spectrometry (ICP-OES), thermal analysis (TG-DTA) and Fourier-transform infrared spectroscopy (FTIR). The resulting ashes from the combustion step were subjected to ICP, nitrogen physisorption, Energy dispersive X-ray spectroscopy (EDX) as well as X-ray diffraction (XRD). ICP results revealed that the SiO2 content in the ashes varies between 42.2 to 81.5 wt.% db and 53.4 to 90.8 wt.% db after acidic pre-treatment with 1 and 5 w/v% acid, respectively. The relative reductions of K2O by the citric acid in yam peel was the lowest (79 wt.% db) in comparison to 92, 97, 98 and 97 wt.% db calculated for corncob, cassava peel, coconut husk and cornhusk, respectively. XRD analysis revealed dominant crystalline phases of arcanite (K2SO4), sylvite (KCl) and calcite (CaCO3) in ashes of the biomass fuels pre-treated with 1 w/v% citric acid due to potassium and calcium ions present. In comparison, the 5 w/v% citric acid pre-treatment produced amorphous, biogenic silica with specific surface areas of up to 91 m2/g and pore volumes up to 0.21 cm3/g. The examined biomass residues are common wastes from food production in Africa without competition in usage with focus application. Our studies have highlighted a significant end-value to these wastes by the extraction of high quality, amorphous silica, which can be considered in applications such as catalyst support, construction material, concrete and backing material

Biogas production from sugarcane waste: assessment on kinetic challenges for process designing

Biogas production from sugarcane waste has large potential for energy generation, however, to enable the optimization of the anaerobic digestion (AD) process each substrate characteristic should be carefully evaluated. In this study, the kinetic challenges for biogas production from different types of sugarcane waste were assessed. Samples of vinasse, filter cake, bagasse, and straw were analyzed in terms of total and volatile solids, chemical oxygen demand, macronutrients, trace elements, and nutritional value. Biochemical methane potential assays were performed to evaluate the energy potential of the substrates according to different types of sugarcane plants. Methane yields varied considerably (5–181 Nm3·tonFM−1), mainly due to the different substrate characteristics and sugar and/or ethanol production processes. Therefore, for the optimization of AD on a large-scale, continuous stirred-tank reactor with long hydraulic retention times (>35 days) should be used for biogas production from bagasse and straw, coupled with pre-treatment process to enhance the degradation of the fibrous carbohydrates. Biomass immobilization systems are recommended in case vinasse is used as substrate, due to its low solid content, while filter cake could complement the biogas production from vinasse during the sugarcane offseason, providing a higher utilization of the biogas system during the entire year

Promoting source separation of Biowaste for a Sustainable Circular Economy in the Baltic Region

BackgroundThe European Union Waste Framework Directive mandates the separate collection and sustainable utilization of biowaste at the source in member states from January 1, 2024, to achieve the EU's target of recycling 65% of municipal solid waste by 2035. However, less than 50% of municipal biowaste is being collected separately in member states. This presents significant challenges for the Baltic countries, where some need to develop new collection systems and waste treatment facilities, while others must improve their existing systems. Moreover, up to 60% of biowaste still ends up in residual waste bins, which poses a concern for the solid waste management system. Study AreaThe cities examined in this study include Bornholm, Lappeenranta, Rostock, and Gdańsk distributed across different countries. The selected cities are located within the geographical vicinity of the Baltic Sea, a brackish inland sea in Northern Europe  (Figure 1).MethodsThis study was a collaborative effort involving experts from Germany, Finland, Denmark, and Poland The methodology employed in this study involved an extensive review of scientific literature and seven discussion meetings from January to March 2023 between involved experts. The research aimed to identify the challenges, gaps, and potential measures to improve the source separation of biowaste in the Baltic region.ResultsManagement of biowaste varies significantly due to consumption patterns, economic wealth, regional policies, technical infrastructure, and public awareness. The studied areas have national-level regulations on biowaste source separation and landfill bans. Aside from Germany, other countries have recently implemented these regulations, leading to a transitional phase in biowaste management.Local authorities often struggle to adapt solutions to their specific context due to limited flexibility and resources. Sharing experiences and knowledge can mitigate repeating mistakes, foster cross-border collaboration, and enhance local authorities' capacity to improve biowaste source separation.</div
