The rapid proliferation of electronic waste, driven by the short lifecycle of smartphones and planned obsolescence strategies, presents escalating global environmental challenges. To address these issues from a systems perspective, this study develops an agent-based modeling (ABM) framework that simulates consumer decisions and stakeholder interactions within the smartphone reuse and recycling ecosystem. The model incorporates key behavioral drivers—privacy concerns, moral norms, and financial incentives—to examine how social and economic factors shape consumer behavior. Four primary agent types—consumers, manufacturers, recyclers, and second-hand retailers—are modeled to capture complex feedback and market dynamics. Calibrated using empirical data from Jiangsu Province, China, the simulation reveals a dominant consumer tendency to store obsolete smartphones rather than engage in reuse or formal recycling. However, the introduction of government subsidies significantly shifts behavior, doubling participation in second-hand markets and markedly improving recycling rates. These results highlight the value of integrating behavioral insights into environmental modeling to inform circular economy strategies. By offering a flexible and behaviorally grounded simulation tool, this study supports the design of more effective policies for promoting responsible smartphone disposal and lifecycle extension.

Influence of Technology on Perceived Obsolescence though Product Design Properties

Formal or perceived obsolescence describes the fact that users decide to stop using a product, even though it still fulfils its function. This is because the design is perceived as obsolete, which also leads to negative product semantics. This is often the case with products that are frequently updated to incorporate the latest technology. The aim of this paper is to understand the influence of technology on the perception of design. To this end, 297 people were surveyed about their perception of formal obsolescence in regard to different elements of a car and a smartphone, based on their design properties: shape, colour and material. In addition, technological attributes (some of which were dystopian) were added to these products to assess the influence of current or obsolete technology on participants’ perception of obsolescence. Possible correlations were assessed by means of a chi-square analysis. The results show that technology does not influence all design properties in the same way, with shape being more important than colour or material. This is especially true for multimedia products, such as vehicle displays or smartphones. The results of this paper can help design engineers to create products that last longer, while also reducing their environmental impact. Full article

Considering the social and ecological obsolescence of the conventional agricultural model and the crisis faced by rural areas, innovative models based on collective initiatives and agroecological practices are emerging. Here, we present the use of a participatory farming lab as a space to reactivate the agrarian sector in rural and periurban areas of Madrid. The specific objectives of this study are: (1) to describe the project; (2) to identify participants’ profiles and motivations and (3) to identify the most socially valued ecosystem services and the actions collectively taken to enhance them. To do so, we have used the living lab conceptual approach and the ecosystem service lens. Data gathering included a combination of qualitative and quantitative techniques, including participant observation, informal and formal meetings, interviews, workshops and surveys. We found a diversity of motivations for enrolling in the program and 20 ecosystem services were selected as socially important. We also describe how the project has contributed to adopting agroecological practices to sustain those ecosystem services. Finally, we discuss the contribution of the project towards new and integrated rural development strategies, including its potential to promote cooperative solutions that enhance farming activity by also providing ecosystem services.
