As a result of this growing concern for environmental issues, a new market for sustainable products has emerged, with engaged consumers driving it even further. It influenced the new trend and resulted in new behaviors in their daily lives, resulting in a more sustainable lifestyle. Several studies on sustainability have increased year after year, including sustainable products, which are on the rise. This study aims to determine the contribution of sustainable product’s attributes on customers' willingness to pay more for sustainable products, mainly to assist the sustainable industry in developing strategies that correspond with the values of sustainable products and also sustainable product consumer values. This study was carried out using quantitative methods using online surveys distributed to respondents who fit the criteria, had an interest in sustainable products, and live in Indonesia. This study resulted in 204 respondents who have used or intend to use sustainable products, dominated by respondents who live in Bandung and Jabodetabek. To identify and analyze the attributes that influence the willingness to pay more for a sustainable product, the researcher uses Structural Equation Modelling (PLS-SEM) to process the survey findings. The results of this study is the willingness to pay more towards sustainable products significantly affected by eco-label, eco-packaging, and local production. From these variables, local production is the key variable that influences customers to spend extra money for sustainable products. This findings demonstrates that the suggested model contributes to the literature and is valuable for understanding in depth the attributes that motivate potential customers to pay more for sustainable products. As a result, companies can get recommendations on how to establish effective marketing campaigns.

This research aims to generate the correlation between several barrier factors: product design barrier, knowledge barrier, cost barrier, and supply source barrier towards Gen-Y customer purchase intention of sustainable fashion in Indonesia. This research is using the theory that stated barrier factors are directly influencing customer purchase intention. A total of 226 respondents all across Indonesia are selected through the non-probability purposive sampling technique. This study's instrument uses questionnaires that have been adjusted in terms of language and evaluated by using validity and reliability testing. The data output from data collection is analyzed with the multiple linear regression techniques. The findings indicate a significant influence between product design barriers, knowledge barriers, cost barriers, and supply source barriers simultaneously towards purchase intention of sustainable fashion among Indonesian Gen-Y. When assessed partially, product design barriers negatively influence purchase intention, and the result is significant. It means that the product design barrier is not a barrier that hinders the purchase intention of sustainable fashion. The knowledge barrier and cost barrier also negatively influence purchase intention of sustainable fashion, but the result is not significant. The supply source barrier has a positive influence on the purchase intention of sustainable fashion. It means there is an actual barrier that hinders the purchase intention of sustainable fashion. This study suggested that business owners make sustainable fashion more accessible on every platform, offline and online, to decrease the supply source barrier.

Poorly managed e-waste can lead to public health and environmental problems resulting from the leakage of toxic e-waste substances. Building upon the integrated e-waste management (IEWM) concept, this study aims to propose an integrated and sustainable e-waste management strategy. It also suggests alternative processes for the effective collection, treatment, and disposal of e-waste. In its first stage of system dynamics modeling, the study employed an integrated approach comprising interviews and the Causal Loop Diagram (CLD). Based on the stakeholders’ collaboration and resource management, two alternative scenarios have been proposed: 1) integration to community collection; and 2) scavengers as collection agents. Both scenarios have been implemented by means of public–private partnership (PPP) with industries. Interrelating factors such as governance, physical system, and sustainability aspects have also been analyzed. The proposed alternative scenarios can benefit the municipal government in terms of improving the existing e-waste management channels and, therefore, facilitating a better e-waste management system. They can also ensure better collaboration with related stakeholders in recycling, manufacturing, smelter industry processes, etc., together with strengthening the relationship between the community and the informal sector.
