Preferences and valuation of small-scale wastewater treatment system maintenance using discrete choice method: Case of community-managed system in Jakarta, Indonesia.

The focus of public service delivery on sustainability and universal access has enabled the enactment of many community-based programs in Indonesia. However, relevant studies that examine the willingness to pay among households that utilize community-managed facilities are lacking, despite it being one of the most important factors for maintenance and a strong indicator of commitment. In the present study, we aimed to estimate household users' preferences and willingness to pay (WTP) to understand their demand for related services.

Towards sustainability through the circular economy of plastic packaging waste management in Rayong Province, Thailand.

The circularity of plastic packaging waste (PPW) material via recycling is critical to its circular economy towards sustainability and carbon neutrality of society. The multi-stakeholders and complex waste recycling loop of Rayong Province, Thailand, is herein analysed using an actor-network theory to identify key actors, roles, and responsibilities in the recycling scheme. The results depict the relative function of three-actor networks, namely policy, economy, and societal networks, which play different roles in PPW handling from its generation through various separations from municipal solid wastes to recycling.
