Municipal waste management is still a significant problem for solid waste issues in Indonesia. Only 60 to 70% of the waste generated is disposed of in landfills, the rest is dispersed in different areas. The potential for leachate pollution, greenhouse gases, and a waste of non-renewable natural resources can occur due to municipal waste management problems not being optimal. Municipal waste management needs a holistic concept that would include upstream to downstream stages. This paper comprehensively reviews municipal waste management with a zero waste concept based on management, development, measuring, implementations, strategies, potentials, and challenges in Indonesia. The zero waste concept offers waste management, starting with waste elimination, recycling, reduction, and recovery of used goods. Several municipalities around the globe, such as Canberra, Adelaide (Australia), Stockholm (Sweden), Nova-Scotia (Canada), and San Francisco (United States), have decided on targets for zero waste cities. Indonesia is still implementing waste management that accentuates disposal in landfills, so there needs to be a literature study related to the management, development, measuring, implementations, strategies, potentials, and challenges of Indonesia’s zero waste concept.

The concept of green marketing mix is as well as the conventional marketing mix refers to the satisfaction of customer needs, wants, and desires related to the maintenance and preservation of the environment.

The implementation of a green marketing strategy requires a fundamental, comprehensive and integrated approach in all functional aspects of marketing, including the overall marketing mix, such as product design, pricing, location and promotion.

This paper mainly aims to provide an overview of the waste-to-energy project, including the current status, challenges, future vision, and overall project benefits, to show how Amman City has made a reasonably successful step toward implementing waste-to-energy technologies for urban sustainability and resource efficiency. This research is an observational study with a qualitative analysis approach. This study used secondary data from 2003 to 2020 from the Al Ghabawi landfill of Amman City by reviewing the document literature, conducting site visits, and interviewing the waste-to-energy project manager. Waste-to-energy projects provide environmental, energy, and economic benefits that show the positive impact of the waste-to-energy project in Amman City. Therefore, the challenge is to encourage the rational use of natural resources and make people participate in waste-to-energy projects. This challenge is analyzed on the basis of the stakeholders, policymakers, and donors who play a major role in reducing pollution by using landfill gas for energy production, promoting waste recycling, and making landfill gas projects economically feasible. This assessment can initially contribute to the policy formulation process. Urban planning works for Amman's vision of a sustainable and resilient city.
