Plastic Pollution: Indonesia's Pressing Environmental Crisis

Indonesia is facing a critical environmental issue with plastic waste. The country is second only to China in terms of contributing plastic waste to the ocean, with an estimated 600,000 tonnes of plastic waste ending up in the sea each year. This plastic waste crisis not only affects Indonesia's oceans but also its rivers, with four of its rivers ranking among the 20 most polluted rivers globally. The crisis is driven by factors such as the cheap production of plastic products, the lack of awareness about the environmental impact of plastic waste, and the challenges in managing the large volume of waste generated by its population of 250 million people. While the Indonesian government has recognised the urgency of addressing this issue, more decisive action and effective waste management practices are needed to combat the country's significant contribution to plastic pollution.

Indonesia's plastic packaging problem

Indonesia has a significant plastic waste problem, with plastic pollution extending beyond the ocean and into the nation's rivers. In 2019, Indonesia ranked second globally as a major contributor to plastic waste, with an estimated 3.22 million metric tons of plastic waste dumped into the ocean surrounding the country annually, according to a study by the University of Georgia. This figure is supported by the Indonesian Institute of Sciences, which estimates that Indonesia contributes more than 600,000 tons of plastic waste to the ocean each year.

The plastic waste crisis in Indonesia is exacerbated by the country's lack of effective waste management practices and recycling infrastructure. Data from Nature Communications revealed that four of Indonesia's rivers—Brantas, Ciliwung, Citarum, and Progo—are among the 20 most polluted rivers in the world due to plastic waste. The high levels of plastic pollution in these rivers have detrimental effects on the environment and local communities, as they serve as a source of food and water. The clogging of streams and rivers by plastic waste also causes harm to wildlife, such as birds and turtles that ingest non-biodegradable materials, and increases the likelihood of flooding, posing further risks to surrounding communities.

Indonesia's plastic waste problem is influenced by a combination of factors, including the widespread use of plastic products, the lack of awareness about the environmental impact of plastic waste, and the country's role in receiving imported plastic waste from other countries. The affordability and convenience of plastic products in Indonesia contribute to their prevalence, with plastic bags, tables, and chairs made from plastic commonly found throughout the country. Additionally, there is a lack of awareness among the public about the negative consequences of plastic waste on the environment, leading to careless disposal practices.

Indonesia has also been a target for exporters from wealthy countries, particularly after China banned plastic waste imports in 2018. Despite tightening regulations and making progress in reducing the inflow of contaminated and unrecyclable plastic waste, Indonesia continues to struggle with the influx of imported plastic waste. The country's limited waste management and recycling capabilities, coupled with challenges in enforcing regulations, contribute to the accumulation of plastic waste within its borders.

To address Indonesia's plastic packaging problem, comprehensive measures are necessary. These include improving waste management practices, increasing public awareness about the environmental impact of plastic waste, and strengthening regulations on imported plastic waste. By implementing these measures and encouraging sustainable alternatives to plastic packaging, Indonesia can make significant strides in mitigating its plastic waste crisis.

Plastic waste in rivers

Indonesia is facing a plastic waste crisis, with the problem extending beyond the ocean and into the nation's rivers. Four of Indonesia's rivers—Brantas, Ciliwung, Citarum, and Progo—are among the 20 most polluted rivers in the world in terms of plastic waste. The country's plastic packaging problem leads to the clogging of streams, harming wildlife such as birds and turtles that ingest non-biodegradable materials.

The crisis is driven by a combination of factors, including a population boom, the widespread use of plastic containers and wrapping, and a longstanding culture of disposing of rubbish in ditches and streams. The country's rapid development has also contributed to the issue, with local authorities struggling to keep up with the dramatic expansion of waste generation.

The Indonesian government has recognised the urgency of addressing the plastic waste problem and has taken some steps to mitigate it. They have pledged to reduce plastic debris by 70% by 2025 and are structuring a national program to tackle land-based waste management, dedicating up to $1 billion to reduce plastic pollution. However, some environmentalists and scholars remain sceptical about the effectiveness of current government efforts, particularly regarding the enforcement of regulations.

The plastic waste crisis in Indonesia's rivers has attracted international attention, with social media playing a crucial role in raising awareness. Images of choked waterways have led to increased public concern and a shift in attitudes towards the issue. While the army has been deployed to help clear plastic waste, the problem persists due to the constant and monumental influx of plastic.

To effectively address the plastic waste crisis in Indonesia's rivers, a multifaceted approach is necessary. This includes improving waste management practices, strengthening regulations and enforcement, promoting education and awareness, and investing in infrastructure and technologies for sustainable waste management.

Plastic waste in the ocean

Indonesia is the fourth most populous country in the world, with a population of 250 million people. It is also the second-largest plastic polluter, producing 3.2 million tons of unmanaged plastic waste annually, of which 1.29 million tons end up in the sea. The country generates approximately 7.8 million tons of plastic waste per year, with 4.9 million tons of it being mismanaged. This includes plastic waste that is uncollected, disposed of in open dumpsites, or leaked from improperly managed landfills.

The plastic waste crisis in Indonesia extends beyond the ocean, impacting the nation's rivers and coastlines. Four of Indonesia's rivers, Brantas, Ciliwung, Citarum, and Progo, are among the 20 most polluted rivers globally. Rivers carry and discharge 83% of the annual plastic debris that leaks into the marine environment from land-based sources. The plastic waste clogs streams, harming wildlife such as birds and turtles that ingest non-biodegradable materials, and litters beaches while accumulating in landfills.

The Indonesian government has recognized the urgency of addressing the plastic waste crisis and has implemented various measures to reduce plastic usage and improve waste management practices. In recent years, Indonesia has tightened its regulations on imported plastic waste, reducing the volume of tainted waste entering the country. Additionally, the government has adopted presidential decrees aimed at improving household waste management and marine debris management.

Despite these efforts, the plastic waste problem persists, and Indonesia continues to contribute significantly to plastic pollution in the ocean. The crisis is exacerbated by the low recycling rate in the country, with very little plastic being recycled. The plastic waste in the ocean poses a threat to marine ecosystems and human health, underscoring the need for continued efforts to address this pressing environmental issue.

Landfills and their impact

Indonesia is facing a severe plastic waste crisis, with its rivers and oceans inundated with plastic pollution. The country's landfills play a significant role in this crisis, impacting both the environment and human health.

Landfills are sites designed to store garbage and reduce the immediate effects of trash on human health and the environment. Modern landfills are structured to minimize the contamination of surrounding soil or water. They are lined with clay and a thin layer of flexible plastic to allow for the collection of leachate, a liquid that passes through the landfill and draws out toxins. However, despite these measures, landfills remain a significant source of environmental and health hazards.

The Bantar Gebang landfill in Jakarta, Indonesia's largest, receives over 5,000 tons of solid waste daily. Landfills like Bantar Gebang contribute to environmental degradation through several mechanisms. Firstly, they release methane, a potent greenhouse gas, as organic waste decomposes. Methane significantly contributes to air pollution and climate change. Secondly, landfills contaminate groundwater as chemicals and leachate seep into the ground, eventually reaching rivers, lakes, and other water sources. This contamination can create "dead zones" where animals cannot survive due to a lack of oxygen. Additionally, the creation of landfills often involves the destruction of natural habitats, resulting in habitat loss for wildlife.

The health risks associated with living near landfills are also significant. Studies have shown that people residing near hazardous waste landfills have an increased risk of health issues, including respiratory problems, eye irritation, and congenital malformations in children. These health risks disproportionately affect minority and low-income communities, as landfills are more often constructed near these areas.

To mitigate the impact of landfills, it is essential to reduce reliance on them. This can be achieved by adopting sustainable practices, such as recycling, composting, and avoiding single-use plastics. By minimizing the amount of waste that ends up in landfills, we can reduce their environmental and health impacts and move towards a more sustainable future.

Plastic credits and other solutions

Indonesia is facing a significant plastic waste problem, with the issue extending beyond the ocean and into the nation's rivers. The country's plastic packaging waste leads to the clogging of streams, harming wildlife and littering beaches and landfills.

To address this crisis, Indonesia has implemented several solutions, including tightening regulations on imported plastic waste and taking steps to reduce the flow of plastics into the country. In addition, the Indonesian government has recognised the urgency of addressing plastic waste pollution and is working towards improving waste management practices.

One controversial solution that has been proposed is the use of plastic credits. Plastic credits are financial incentives that motivate private sector investment in waste management infrastructure and processes. They are intended to bridge the gap between current capabilities and the desired outcomes of waste reduction and recycling. However, critics argue that plastic credits are primarily greenwashing schemes used by polluting industries to delay addressing the root causes of their toxic operations.

To ensure the effectiveness and credibility of plastic credits, several considerations must be made. Clear and uniform definitions and standards for plastic credits programs are necessary to maintain consistency and credibility. Additionally, the inherent risks associated with plastic credits, such as the potential for greenwashing, must be carefully managed to benefit all stakeholders, especially those in the informal waste management sector.

While plastic credits can drive investments in waste collection and recycling infrastructure, they should not be relied upon as a standalone solution. Instead, they must be part of a broader strategy that includes reducing plastic use, improving product design, and implementing robust waste management systems to achieve genuine sustainability.

Other solutions to Indonesia's plastic waste problem include:

• Improving waste collection coverage and providing better access to waste management facilities, especially in rural areas.
• Increasing national sanitation campaigns to educate communities about healthy waste behaviours and reduce the direct disposal of waste into waterways.
• Investing in well-managed final disposal sites and upgrading existing sites near waterways.
• Optimising the use of existing structures in waterways and drainage systems to prevent plastic waste from reaching the sea.
• Promoting a circular economy to reduce plastic consumption and prevent plastic pollution at the source.
• Implementing cost-effective and impactful policy instruments, such as taxes and incentives, to reduce plastic usage and encourage recycling.
