This research contributes to understanding and shaping systems for OFMSW separation at urban Small and Medium Enterprises (SMEs, such as offices, shops and service providers). Separating SMEs’ organic fraction of municipal solid waste (OFMSW) is both an opportunity and a serious challenge for the transition towards circular cities. It is an opportunity because OFMSW represents approximately 40% of the total waste mass generated by these companies. It is challenging because post-collection separation is not feasible for OFMSW. Therefore, SMEs disposing of waste should separate their solid waste so that processing the organic fraction for reuse and recycling is practical and attainable. However, these companies do not experience direct advantages from the extra efforts in separating waste, and much of the OFMSW ends up in landfills, often resulting in unnecessary GHG emissions. Therefore, governments and waste processors are looking for ways to improve the OFMSW separation degree by urban companies disposing of waste through policies for behaviour change.There are multiple types of personnel at companies disposing of waste. These co-workers act according to their values, beliefs and norms. They adapt their behaviour continuously, influenced by the physical environment, events over time and self-evaluation of their actions. Therefore, waste separation at companies can be regarded as a Socio-Technical Complex Adaptive System (STCAS). Agent-based modelling and simulation are powerful methods to help understand STCAS. Consequently, we have created an agent-based model representing the evolution of behaviour regarding waste separation at companies in the urban environment. The model aims to show public and private stakeholders involved in solid waste collection, transport and processing to what extent behaviour change policies can shape the system towards desired waste separation degrees.We have co-created the model with participants utilising literature and empirical data from a case study on the transition of the waste collection system of a business park located at a former harbour area in Amsterdam, The Netherlands. First, a conceptual model of the system and the environment was set up through participatory workshops, surveys and interviews with stakeholders, domain experts and relevant actors. Together with our case participants, five policies that affect waste separation behaviour were included in the model. To model the behaviour of each company worker’s values, beliefs and norms during the separation and disposal of OFMSW, we have used the Value-Belief-Norm (VBN) Theory by Stern et al. (1999). We have collected data on waste collection behaviour and separation rates through interviews, workshops and a literature study to operationalise and validate the model.Simulation results show how combinations of behaviour profiles affect waste separation rates. Furthermore, findings show that single waste separation policies are often limitedly capable of changing the behaviour in the system. Rather, a combination of information and communication policies is needed to improve the separation of OFMSW, i.e., dissemination of a newsletter, providing personal feedback to the co-workers disposing of waste, and sharing information on the (improvement of) recycling rates.This study contributes to a better understanding of how policies can support co-workers’ pro-environmental behaviour for organic waste separation rates at SMEs. Thus, it shows policymakers how to stimulate the circular transition by actively engaging co-workers’ waste separation behaviour at SMEs. Future work will extend the model’s purpose by including households and policies supporting separating multiple waste types aimed at various R-strategies proposed by Potting et al. (2016).

To achieve the “well below 2 degrees” targets, a new ecosystem needs to be defined where citizens become more active, co-managing with relevant stakeholders, the government, and third parties. This means moving from the traditional concept of citizens-as-consumers towards energy citizenship. Positive Energy Districts (PEDs) will be the test-bed area where this transformation will take place through social, technological, and governance innovation. This paper focuses on benefits and barriers towards energy citizenships and gathers a diverse set of experiences for the definition of PEDs and Local Energy Markets from the Horizon2020 Smart Cities and Communities projects: Making City, Pocityf, and Atelier.
To achieve emission reduction targets and to improve local air quality of cities, the uptake of Electric Freight Vehicles (EFV) is essential. Knowledge concerning why companies do adopt EFV is lacking. Research about the diffusion of innovations and the market of EFV shows that frontrunner companies with an innovative or early adopting mindset are adopting (or willing to adopt) EFV. Increase in demand of EFV by such companies can help take a step forward towards mass production of EFV and eventually reduction in purchase cost of EFV. The main objective of this paper is to get insights into the decision-making attributes of frontrunner companies. A qualitative approach was used and 14 interviews were conducted among frontrunner companies delivering goods in the city of Amsterdam. Results show that innovators and early adopters are all motivated by socially or environmentally positive effects of EFV. Strategic motives played a role for all companies who already adopted EFV. All companies wanted to adopt EFV but technical limitations, due specialrequirements for the goods transported, are a reason to not adopt EFV. Getting insights into the preferences of frontrunner companies, the (local) authorities can adjust their policy, schemes and sustainability campaigns to attract more companies adopting EFV. Manufacturing companies can use the insights from this research to adapt their vehicle technology to answer needs of the potential customer for faster adoption rate.
In this project I will examine models of local energy production and management, comparing the nine Zero emission neighbourhoods, as developed and monitored by the ZEN research centre at NTNU with the Friesian towns that are part of a new research project in the Netherlands (see above). Secondly, connected to this empirical part, I aim to examine and compare the policies and opportunities for prosumers and small and/ or cooperative businesses in Norway and The Netherlands.
