The role of waste banks in the reduction of solid waste sent to landfill in Semarang, Central Java, Indonesia

Abstract

Approximately 1,000 tonnes of solid waste are generated in Semarang every day, only 850 tonnes of which are transferred to the Jatibarang Landfill. Solid waste that is not transferred to the landfill can trigger environmental and health problems. With the help of community groups, reduction of solid waste is achievable using ‘the three Rs’ of waste reduction and the implementation of waste banks. Waste banks could act as mediums for depositing waste, improve the socio-economic status of local residents, and develop community connections. Waste banks improve the volume of waste reduction and reduce landfilled waste, helping to extend the operational life of landfills. This study examined the role of waste banks in Semarang and the potential to improve waste management based on the sampling of solid waste generation and composition. This topic was investigated with a purposive sampling method. Results showed that the existing system of waste banks in Semarang is ineffective in reducing waste. However, the system could be improved by increasing waste bank usage, including for various types of valuable waste in Semarang.

Quantification and characterization of household waste in Dumai Timur District, Dumai City, Riau, Indonesia as a measure towards circular economy.

“…These table and figure show that most of the people in Dumai Timur District's solid waste mainly consists of products made from organic materials (such as food and backyard waste), and plastics. Similar results were shown in previous studies located in Medan, Surabaya, and Semarang; majority of Indonesia's cities generate organic waste the most, with over 60% of the total solid waste generated, followed by plastic and paper waste [18]- [20]. having the most economic potential for over Rp 520 million .…”

Analysis of Potential RDF Resources from MSW Landfills in Major Cities of Indonesia

“…The composition of this waste differed from that reported by Budihardjo et al (2019) in many landfills in Semarang, Indonesia. The percentage of organic waste in Semarang landfills was only 48.41%.…”

The effectiveness of household waste management based on the waste alms concept by elementary school students

“…An efficient landfill system can improve solid waste management in cities by increasing the amount of waste that is eventually landfilled. The system will improve waste reduction and waste disposal within the city while extending the life of landfills (Budihardjo et al, 2019;Raharjo et al, 2017). In addition, when these systems work effectively, the amount of residual waste in cities can be reduced, the environment cleaner, and health indicators can be improved (Budihardjo et al, 2019;Ulhasanah & Goto, 2018).…”
