Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Purpose In this study, we sought to explore the sustainability of waste supply chains with respect to energy efficiency of first-mile waste collection systems and quality of waste. In particular, we sought to understand the co-producing roles of different actors in the waste service triad, ranging from waste services providers to the individual household. Design/methodology/approach The study included multiple sources of evidence: data during brainstorming sessions, semi-structured interviews, and site visits with officials from a municipality in Sweden and its waste service provider. These data were triangulated with that from a focus group with households members and analysed based on the different waste collection systems. Findings The findings reveal the tension between energy efficiency of waste collection logistics and the quality of the waste. Consumers, as co-producers of logistic services for effective of sorting and moving waste, may provide input to improve energy efficiency and quality. Practical implications This study provides principles for policymakers and practitioners to evaluate energy efficiency of waste management options with consideration for the quality of waste. In addition, ‘quality of waste’ as a concept might provoke new thoughts on how to involve the consumer in the recovery of resources. Original/value Few studies have focused on the end consumer’s role in waste supply chains. By considering waste as resource (raw material input) to the supply chain and the consumer as the supplier of this input, this study provides a new way of thinking about waste collection.

- Logistics operations are energy-consuming and impact the environment negatively. Improving energy efficiency in logistics is crucial for environmental sustainability and can be achieved by increasing the utilisation of capacity. This paper takes an interactive approach to capacity utilisation, to contribute to sustainable freight transport and logistics, by identifying its causes and mitigations. From literature, a conceptual framework was developed to highlight different system levels in the logistics system, in which the energy efficiency improvement potential can be found and that are summarised in the categories activities, actors, and areas. Through semi-structured interviews with representatives of nine companies, empirical data was collected to validate the framework of the causes of the unutilised capacity and proposed mitigations. The results suggest that activities, such as inflexibilities and limited information sharing as well as actors’ over-delivery of logistics services, incorrect price setting, and sales campaigns can cause unutilised capacity, and that problem areas include i.a. poor integration of reversed logistics and the last mile. The paper contributes by categorising causes of unutilised capacity and linking them to mitigations in a framework, providing a critical view towards fill rates, highlighting the need for a standardised approach to measure environmental impact that enables comparison between companies and underlining that costs are not an appropriate indicator for measuring environmental impact.
