In a country infamous for being the second-biggest contributor of plastic waste to the oceans, a city in West Java has achieved a close to 100 percent segregation rate. This is how Depok transformed its waste system.
Waste is rapidly becoming one of the most pressing issues of all time. More than a decade after Bandung’s Leuwigajah dumpsite disaster in West Java, in which 143 people died buried under a waste avalanche, there is still no strict law enforcement to divert waste from filling up landfills.
Some subsequent laws, such as the Waste Management Law enacted in 2008, have required Indonesian citizens to sort their waste to increase the 3R (recycle, reduce, reuse) system in each municipality. However, those laws have shown very limited results. Segregation rates among households in Indonesia remain persistently low according to Bekasi-based waste-management organisation Waste4Change.
Worldwide, 8 million tons of plastic end up in oceans every year, 16 percent of which comes from Indonesia as the second-biggest contributor. In 2016, the country alone generated 3.2 million tons of plastic waste, of which 1.29 million ended up in the oceans. Fortunately, at the World Oceans Summit in March, Indonesia pledged to put up $1 billion a year to reach a 70 percent reduction in marine waste by 2025.
The national government should look at some local communities in the city of Depok in West Java that have proven to be successful models in diverting hundreds of tons of waste from going to landfills and leaking into the oceans.
From almost nil to almost 100 percent segregation rates, a pocket of about 100,000 households in Depok have managed to divert almost 72 percent of all their household food scraps and packaging from landfills.
After a year of effort, community leaders revealed that the city managed to divert 148 tons of waste daily from landfills — of which approximately 99 tons comprised organic waste from households, 27 tons of the city’s organic and landscape material, and 22 tons of recyclables — to waste banks, approximately 12 percent of the total waste generated in Depok. More than 100,000 households have been segregating their waste, increasing recycling rates.
M. B. Junerosano, managing director of Waste4Change, explains some of the key success factors of the Depok system.
“The management has an integrated infrastructure and processing system, starting with sorting at the source: Organic waste is required to be placed in the bucket, inorganic waste is sent to waste banks or for recycling processing, and residue to landfill. If there is no sorting, then the waste will not be transported and any illegal dumping will be prosecuted,” he said.
A strict enforcement of the new system and regulations was also key. They also had 25 waste police officers covering Depok to patrol for offenders. About 300 people were prosecuted for their inaction in segregating their waste.
Another step was to change the collection schedule in order to have a different vehicle and timing for each material type. Organic waste was collected every other day, recyclables had to be transported to waste banks, and the residue was picked up once a week. This was necessary to provide a clear and rigorous framework for communities not to be confused between organic and inorganic waste.
The local Depok team was inspired by efforts overseas. Zamrowi heard about Depok’s sister-city partnership with Osaki in Japan and took the opportunity to learn how to drive segregation of waste within households. Since then, Depok has always looked up to Osaki as a role model. A collaboration between the two has been crucial for the Depok city officials in order to gain technical knowledge.
“Before anything happened, officials were skeptical about the possibility of segregation on a large scale. However, we have always felt that if other countries could do it, then so could Indonesians. If Depok starts the ball rolling, then other cities could follow and get inspired,” Zamrowi said.
“The Bucket Party system in Depok shows evidence that an implemented and enforced solid waste management system is important in successful solid waste management,” Junerosano added.
Today, UPS coordinator Isnarto, who has been collaborating with Zamrowi to make Depok a successful case study, is proud to witness organic waste turning into compost.
“Managing and recycling waste is a sign that we are civilised,” he said. “It shows that we know how to take care of ourselves and our environment.”
