研究成果概要
It was difficult to conduct field research due to COVID-19, we changed the direction of our research. We analyzed the informal sector in waste management to understand the current waste management situation of Indonesia. We analyzed the recycling contributions and average income of dumpsite waste pickers in Indonesia. The average monthly weight of collected recyclables on an individual basis varied between 81.0 and 63.3kg, depending on the number of informal recyclers in the household. The estimated total weight of collected recyclables was 3617.6 tons per month. Bosses sold these collected recyclables to different recycling factories depending on the expected profit. It was estimated that the activities of the waste pickers produced at least 725.4 tons of recycled pellets of soft plastic and 280.8 tons of recycled pellets and flakes of hard plastic. The informal recycling rate for all waste and non-organic waste on the site was 1.6% and 9.3%. The average household income of a waste picker was USD 211.3. The six kinds of work associated with waste picking exist in the site. The total amount of debt repayments was within 20% of the total income. The average amount of saving was about 10% of the total income.
