Abstract
In Jakarta, Indonesia, municipalities collect plastic mixed with other waste, scavengers recover plastic waste by picking through waste, and some citizens recover plastic at community-based waste management centers called waste banks. The fact that each stakeholder operates separately means that the actual amount of plastic recycled in Jakarta is not well-known. This research evaluated the amount of plastic recovered at the source, identified the amount of plastic waste recycled using a material flow analysis (MFA), and proposed alternative solutions to improve plastic waste management in Jakarta. Through interviews, the amount of plastic waste recovered was determined; each scavenger recovers 239 kg/month and each waste bank recovers 260 kg/month. Through the MFA, the rate of plastic recycled was identified as 24%, leaving 76% of plastic waste in landfills or in the environment. There are several actions that can be taken to promote higher recycling rates in Jakarta: conducting separation at source; integrating scavenger activity with waste bank and municipality collection; providing a material recovery facility at final disposal sites using sorting technology to recover plastics; and using alternative technology such as chemical recycling or thermal treatment to treat plastic waste that is not readily recycled through mechanical recycling.
