Little progress has been made in recent years toward achieving a fully circular economy by 2050. Implementing circular urban supply chains is a major economic transformation that can only work if significant coordination problems between the actors involved are solved. On the one hand, this requires the implementation of efficient urban collection technologies, where process industries collaborate hand-in-hand with manufacturers, urban waste treatment, and city logistics specialists and are supported by digital solutions for visibility and planning. But on the other hand, it also requires implementing regional and urban ecosystems connected by innovative CO2-neutral circular city logistics systems smoothly and sustainably managing the regional flow of resources and data, often at large and with interfaces between industrial processes and private and private and public actors. What are relevant research questions from a city logistics perspective?

A large share of urban freight in cities is related to construction works. Construction is required to create attractive, sustainable and economically viable cities. When activities at and around construction sites are not managed effectively, they can have a negative impact on the cities liveability. Construction companies implementing logistics concepts show a reduction of logistic costs, less congestion around the sites and improved productivity and safety. The client initially sets the ‘ground rules’ for construction in the tendering process. This paper explores how tendering for construction projects can support sustainable urban construction logistics. We explore the potential for tendering construction projects, by both public and private clients, for sustainable urban construction logistics and we present a conceptual framework for specifying ‘logistics quality’ as a quality criterion for EMAT (Economically Most Advantageous Tender). Our exploration results in questions for further research in tendering for sustainable urban construction logistics.
This paper presents challenges in city logistics for circular supply chains of e-e-waste. Efficient e-waste management is one of the strategies to save materials, critical minerals, and precious metals. E-waste collection and recycling have gained attention recently due to lower collection and recycling rates. However, implementing circular urban supply chains is a significant economic transformation that can only work if coordination decisions are solved between the actors involved. On the one hand, this requires the implementation of efficient urban collection technologies, where waste collection companies collaborate with manufacturers, urban waste treatment specialists, and city logistics service providers supported by digital solutions for visibility and planning. On the other hand, it also requires implementing urban and regional ecosystems connected by innovative CO2-neutral circular city logistics systems. These systems must smoothly and sustainably manage the urban and regional flow of resources and data, often at a large scale and with interfaces between industrial processes, private, and public actors. This paper presents future research questions from a city logistics perspective based on a European project aimed at developing a blueprint for systemic solutions for the circularity of plastics from applications of rigid PU foams used as insulation material in refrigerators.

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).
Road freight transport contributes to 75% of the global logistics CO2 emissions. Various European initiatives are calling for a drastic cut-down of CO2 emissions in this sector [1]. This requires advanced and very expensive technological innovations; i.e. re-design of vehicle units, hybridization of powertrains and autonomous vehicle technology. One particular innovation that aims to solve this problem is multi-articulated vehicles (road-trains). They have a smaller footprint and better efficiency of transport than traditional transport vehicles like trucks. In line with the missions for Energy Transition and Sustainability [2], road-trains can have zero-emission powertrains leading to clean and sustainable urban mobility of people and goods. However, multiple articulations in a vehicle pose a problem of reversing the vehicle. Since it is extremely difficult to predict the sideways movement of the vehicle combination while reversing, no driver can master this process. This is also the problem faced by the drivers of TRENS Solar Train’s vehicle, which is a multi-articulated modular electric road vehicle. It can be used for transporting cargo as well as passengers in tight environments, making it suitable for operation in urban areas. This project aims to develop a reverse assist system to help drivers reverse multi-articulated vehicles like the TRENS Solar Train, enabling them to maneuver backward when the need arises in its operations, safely and predictably. This will subsequently provide multi-articulated vehicle users with a sustainable and economically viable option for the transport of cargo and passengers with unrestricted maneuverability resulting in better application and adding to the innovation in sustainable road transport.
A number of universities of applied sciences do a lot of research in the field of sustainable last mile logistics. Collaboration and coordination take place through joint projects or through seminars. However, this collaboration could be more structured so that researchers can always take full advantage of each other's knowledge and are not dependent on having or not having joint projects or seminars. This also concerns the question of how these studies can gain extra added value through joint programming (this can partly be done in the development of a tool/benchmark, see previous point), but also in having and getting research and knowledge from the different regions. Within the new research agenda of the Logistics Knowledge Agreement (the lectors platform of the CoE KennisDC Logistics), urban logistics has been named as one of the four core themes on which the involved universities of applied sciences want to collaborate across regions. In addition, there is only limited cooperation in the field of education around the theme of “urban logistics”. Students who want to graduate in urban logistics or do internships must therefore first learn a lot.
