Many countries are under escalating pressure to meet legally binding targets in relation to recycling and waste management. This paper explores how innovative tools, including blockchain, economic incentives, and gamification, encourage consumer adoption of a novel household waste management system. We focus on developing a comprehensive framework that combines UTAUT2 (the unified theory of acceptance and use of technology 2) with novel features in the waste management context and additional behavioral construct, intention to recommend the system to others. We tested the proposed model using the partial least square structural equation modeling approach based on a survey of 400 respondents. The results indicate that in addition to effort expectancy, social influence, and hedonic motivation, trust, a property of blockchain technology, also impacts the respondent’s behavioral intention to use the new system. Furthermore, trust has a significant effect on both the level of system use and intention to recommend waste management system to others. The role of gamification was identified as a moderator between behavioral intention and system use and between trust and system use but not between system use and facilitating conditions. This result demonstrates that gamification can be valuable to increase adoption in users with otherwise low levels of behavioral intention. However, we did not find a strong link between either economic incentives, facilitating conditions, or performance expectancy and behavioral intention. The paper concludes by presenting the application of the proposed framework and the implications for the design of future consumer-facing waste management systems. The introduction of the novel features such as blockchain and gamification is discussed. publishersversion published

Journal of Cleaner Production, 362(August), 1-10. [132328]. https://doi.org/10.1016/j.jclepro.2022.132328 --- Funding Information: The authors acknowledge the financial support provided by Fundação para a Ciência e a Tecnologia (FCT) Portugal under the project UIDB/0415s2/2020 - Centro de Investigação em Gestão de Informação (MagIC) . Project BEE2WasteCrypto (reference IDT-COP 45933) leading to this work is co-financed by the European Regional Development Fund (ERDF) through the Operational Program for Competitiveness and Internationalisation COMPETE 2020, the Lisbon Portugal Regional Operational Program – LISBOA 2020 and by the Portuguese Foundation for Science and Technology – FCT under CMU Portugal Program. New technological solutions can encourage lower household waste production and higher levels of waste separation. This paper focuses on analyzing the role of different behavioral factors, such as empowerment and pro-environmental behavior (PEB), have on citizens' intention to use a novel household waste management and separation system and how these interact with the financial incentives typically applied in this area, pay-as-you-throw (PAYT) and save-as-you-throw (SAYT). The proposed model was tested in Portugal using the structural equation modeling approach. Survey data from 400 respondents found that empowerment plays a vital role in adopting an innovative waste management system. The research discerns pro-environmental behavior (PEB) both as an antecedent and a moderator between system use and empowerment, system use and behavioral intention, and also between system use and financial incentives. We discovered that for people with low perceived PEB, PAYT actually reduces the use of the new waste management system, while SAYT can increase the use of the system. Furthermore, increasing the empowerment of users in the system can work exceptionally well at encouraging consumers that already have a high level of PEB. The paper concludes with a discussion section about the developed framework's application and implication in the waste management sector. This study is valuable for understanding how citizens will adopt a new waste management system and essential for encouraging citizens to engage in recycling behavior regularly. publishersversion published
