Insider ethnographic analysis is used to analyze change processes in an engineering department. Distributed leadership theory is used as conceptual framework.
Worldwide, plastic cups are used for serving drinks. Some typical examples of large-scale consumption are large concerts and festivals. As a part of the BIOCAS project, which focusses on the valorization of biomass through various routes, a PHA biobased festival cup was developed and created to reduce the impact of current fossil plastics. The role of VHL was to assess the environmental impact. The aim of the report is to inform the BIOCAS-partners about the use of plastic cups, and address the environmental impact in comparison with other types of biobased plastic cups and fossil-based cups. This report can serve as a basis for making choices within all different types of (plastic/biobased) cups. Besides, it can be used as a public communication tool about the environmental impact of different types of (plastic/biobased) cup applications.

This booklet contains the analyses and designs that were produced by international teams of students, designers and researchers on the revitalization of public space in the district of Kerkrade – West (Limburg, the Netherlands) in December 2017 during the International Design Workshop (re)CYCLE LIMBURG 2. It was partially built on knowledge, experiences and ideas from the preceding workshop in December 2016. The outcomes of the workshop are mainly presented in the form of drawings, maps, schemes, collages, artistic impressions etc. Both workshops were framed in the interdisciplinary project Kerkrade-West of Zuyd UAS and its Research Centre for Smart Urban ReDesign (SURD).
Hoe kun je een koper stimuleren om niet perse de -op het eerste gezicht- goedkoopste machine of equipment aan te schaffen, maar ook te kijken naar lange termijn waardebehoud en duurzaamheid? Of andersom, hoe vergelijk je aanbod van leveranciers op een mix van criteria waaronder emissies, maar ook het lange-termijn kostenplaatje? Dit project richt zich op mkb-bedrijven in de metaal- en maakindustrie, waar veel ‘kritieke grondstoffen’ bespaard kunnen worden als er ook naar refurbish, remanufacturing en product-as-a-service gekeken wordt op het moment dat een machine vervangen moet worden. Er zal onderzocht worden in hoeverre goed gepresenteerde en samenhangende informatie over ecologische en economische duurzaamheid kan helpen bij het maken van zulke keuzes. Deze informatie wordt gepresenteerd in een beslissingsondersteunende tool. De tool moet inzicht geven over zg. Total Cost of Ownership (TCO), in plaats van enkel de aanschafprijs, en in de eco-impact van verschillende alternatieven. Eco-impact wordt vaak bepaald d.m.v. een zg. Life Cycle Analysis (LCA), waarin de levenscyclus van een product of dienst bekeken wordt van ‘wieg tot graf’. De TCO brengt juist de financiële aspecten (investering, beheer, onderhoud, ‘end-of-life’) over de levensduur in kaart. Maar het komen tot vergelijkbare LCA/TCO berekeningen vraagt afspraken over uitgangspunten en presentatiemethoden in een keten. In het project worden bestaande (reken)methoden op een vernieuwende wijze gecombineerd worden en in co-creatie geschikt gemaakt worden voor sales engineers en inkopers uit het werkveld. Het ontwerpgerichte onderzoek naar bruikbare presentatiemethoden en het mogelijke effect op aankoopgedrag zal vooral plaatsvinden met behulp van zg. ‘mockups’ waarmee de functionaliteit en interface van de tool iteratief getest wordt. Het eindresultaat is een advies over hoe te komen tot implementatie van de methode door de betrokken partijen. Het project kan zo bijdragen aan het introduceren van nieuwe circulaire business modellen in deze sector.
Phosphorus is an essential element for life, whether in the agricultural sector or in the chemical industry to make products such as flame retardants and batteries. Almost all the phosphorus we use are mined from phosphate rocks. Since Europe scarcely has any mine, we therefore depend on imported phosphate, which poses a risk of supply. To that effect, Europe has listed phosphate as one of its main critical raw materials. This creates a need for the search for alternative sources of phosphate such as wastewater, since most of the phosphate we use end up in our wastewater. Additionally, the direct discharge of wastewater with high concentration of phosphorus (typically > 50 ppb phosphorus) creates a range of environmental problems such as eutrophication . In this context, the Dutch start-up company, SusPhos, created a process to produce biobased flame retardants using phosphorus recovered from municipal wastewater. Flame retardants are often used in textiles, furniture, electronics, construction materials, to mention a few. They are important for safety reasons since they can help prevent or spread fires. Currently, almost all the phosphate flame retardants in the market are obtained from phosphate rocks, but SusPhos is changing this paradigm by being the first company to produce phosphate flame retardants from waste. The process developed by SusPhos to upcycle phosphate-rich streams to high-quality flame retardant can be considered to be in the TRL 5. The company seeks to move further to a TRL 7 via building and operating a demo-scale plant in 2021/2022. BioFlame proposes a collaboration between a SME (SusPhos), a ZZP (Willem Schipper Consultancy) and HBO institute group (Water Technology, NHL Stenden) to expand the available expertise and generate the necessary infrastructure to tackle this transition challenge.
PBL is the initiator of the Work Programme Monitoring and Management Circular Economy 2019-2023, a collaboration between CBS, CML, CPB, RIVM, TNO, UU. Holidays and mobility are part of the consumption domains that PBL researches, and this project aims to calculate the environmental gains per person per year of the various circular behavioural options for both holiday behaviour and daily mobility. For both behaviours, a range of typical (default) trips are defined and for each several circular option explored for CO2 emissions, Global warming potential and land use. The holiday part is supplied by the Centre for Sustainability, Tourism and Transport (CSTT) of the BUas Academy of Tourism (AfT). The mobility part is carried out by the Urban Intelligence professorship of the Academy for Built Environment and Logistics (ABEL).The research question is “what is the environmental impact of various circular (behavioural) options around 1) holidays and 2) passenger mobility?” The consumer perspective is demarcated as follows:For holidays, transportation and accommodation are included, but not food, attractions visited and holiday activitiesFor mobility, it concerns only the circular options of passenger transport and private means of transport (i.e. freight transport, business travel and commuting are excluded). Not only some typical trips will be evaluated, but also the possession of a car and its alternatives.For the calculations, we make use of public databases, our own models and the EAP (Environmental Analysis Program) model developed by the University of Groningen. BUAs projectmembers: Centre for Sustainability, Tourism and Transport (AT), Urban Intelligence (ABEL).
