Like many parts of Asia, Indonesia, comprising of more than 17,000 islands, has a fast-growing economy and population, and a huge coastline with many densely populated cities.
In Bali, which attracts about 6.5 million international tourists annually, trash regularly washes up on its once-pristine beaches.
According to a survey on the island's rivers, landfill sites and 950 local households, Bali generates about 1.6 million tonnes of waste each year.
About 303,000 tonnes of waste are plastic, of which 33,000 tonnes leak into Bali's waterways.
The Bali Partnership hopes that Jakarta will use the findings to improve waste management and tackle the problem of plastic waste in oceans.
Two years ago, the government launched a national action plan pledging up to US$1 billion to cut ocean waste by 70 percent by 2025.
