Plastic Waste In Australia: An Annual Crisis

Plastic waste is a pressing global issue, and Australia is a significant contributor. With a recycling rate of just 13-15%, the country generates an estimated 74-76 million metric tonnes of waste annually, including 3.4 million tonnes of plastic. This waste is primarily sent to landfills, with only a small proportion being recycled or recovered through other means. Australia's plastic waste problem is expected to worsen, with predictions of a surge in plastic consumption and a doubling of global plastic usage by 2040. The Australian government has implemented various initiatives and allocated funding to address this issue, but the effectiveness of these measures remains to be seen.

Plastic waste recovery methods

Australia's plastic waste problem is significant and growing, with the amount of plastic consumed in the country set to more than double by 2050. While the Australian government has implemented various policies and plans to reduce plastic waste, such as the 2018 National Waste Policy and the Australian Packaging Covenant, only about 14-15% of plastic waste is kept out of landfills.

To address this issue, several plastic waste recovery methods can be employed:

Recycling

Recycling is the process of collecting, sorting, washing, and reprocessing plastic waste into new products. It helps reduce the amount of waste and lessen the environmental impact of plastics. However, recycling plastic can be inefficient, expensive, and hazardous, and there is often little demand for recycled plastics. Additionally, technical and economic challenges, such as identification, segregation, and the economics of recovering value, can make plastic recycling difficult. Nevertheless, advancements in recycling technologies, such as mechanical recycling and pyrolysis, offer more sustainable options.

Incineration

Incineration is the process of burning plastic waste to generate thermal energy. It requires minimal space and produces ash, flue gas, and heat. The heat generated can be used for power production. However, incineration can release air pollutants and carcinogens if not properly controlled.

Landfill

Landfilling involves burying disposable plastic waste beneath the Earth's surface. While commonly used, it has severe environmental consequences. Landfills provide habitats for insects and rodents, cause soil and aquifer issues, and contribute to air pollution through odor release.

Energy Recovery

Energy recovery methods aim to extract energy from plastic waste. This can include using plastic waste as fuel or converting plastics into liquid or gaseous fuels through pyrolysis, a process that breaks down plastics into smaller molecules. Energy recovery helps address waste disposal problems while also meeting energy demands.

Extended Producer Responsibility

This approach places responsibility on waste generators, including producers, importers, and brand owners, to manage plastic waste effectively. It involves the implementation of user fees and the trading of Extended Producer Responsibility Certificates to establish a market mechanism for plastic waste management.

Plastic waste recycling rates

Australia's recycling rate for plastics remains low, with only 13.1% recovered, though one source states 14%. In 2018-19, Australia generated 75.8 million tonnes of solid waste, a 10% increase over the previous two years. Of this, 38.5 million tonnes were sent for recycling, while 20.5 million tonnes were sent to landfill. Households were the largest contributor to plastic waste, supplying 47% (1.2 million tonnes), followed by manufacturing at 15% (380,000 tonnes).

The country generates 74.1 million metric tonnes of waste annually, including 3.4 million tonnes of plastic. Australia's national recycling rate for plastics is less than 13%, with a slight increase from 9.4% in 2018. The low recycling rate is due to various factors, including the difficulty and cost of recycling, composting, and energy recovery. These methods have not kept pace with consumption and waste generation.

The Australian government has implemented several plans to reduce plastic waste, including the 2018 National Waste Policy, the 2019 National Waste Policy Action Plan, and the Australian Packaging Covenant. The government has also set a goal to recycle or reuse 100% of plastic waste and end plastic pollution by 2040. However, these policies focus on recovery, particularly recycling, rather than reducing plastic production and consumption.

To improve plastic recycling rates, public education on proper recycling practices and sustainable behaviours is essential. Additionally, businesses are embracing sustainable practices, and organisations are collaborating on initiatives such as the National Plastics Recycling Scheme (NPRS) to achieve an 80% reduction in plastic waste entering Australia's environment by 2030. The government is also investing in infrastructure, allocating $250 million to the Recycling Modernisation Fund and advanced recycling solutions to sort, process, and remanufacture plastic.

Plastic waste in landfills

Plastic waste in Australia is a significant environmental concern. The country's recycling rate for plastics is low, with only about 13-15% of plastic waste recycled and the remaining 84-87% ending up in landfills. This contributes to the approximately 70 billion pieces of soft "scrunchable" plastics, including food wrappers, that Australia uses annually.

The high proportion of plastic waste sent to landfills is due to several factors. Firstly, the existing policies and approaches to dealing with plastic waste, such as energy recovery, composting, and recycling, have not kept pace with consumption and waste generation. The recycling of plastics is also inefficient and expensive, and there is little demand for recycled plastics. Furthermore, consumer awareness, behaviour, and infrastructure, along with government policies and initiatives, play a crucial role in influencing plastic recycling rates.

The environmental impact of plastic waste in Australia is significant. It contributes to marine pollution, with approximately 130,000 tonnes of plastic leaking into the marine environment each year, posing threats to wildlife and potential risks to human health. Additionally, plastic bottles, which make up a significant portion of plastic waste, can take up to 1,000 years to break down in landfills.

To address the issue of plastic waste in landfills, Australia has set ambitious targets and initiatives. The government has allocated $250 million to the Recycling Modernisation Fund and plans to work with the private sector to foster a circular economy. The National Plastics Recycling Scheme (NPRS) aims for an 80% reduction in plastic waste entering the environment by 2030. However, to achieve these goals, more effective policies that focus on reducing plastic production and consumption, in addition to improving recycling infrastructure, are necessary.

Plastic waste reduction policies

Australia has been facing a significant challenge when it comes to plastic waste, with existing policies falling short of effectively tackling this issue. The annual plastic waste in Australia is estimated to be a part of the broader waste generation in the country, which stood at 75.8 million tonnes in 2020/21. While the Australian government has implemented various measures to curb plastic waste, only about 14%-15% of plastic waste has been kept out of landfills through recycling, composting, or energy recovery.

To address this pressing issue, the following comprehensive policies and strategies can be implemented to significantly reduce plastic waste in Australia:

Encourage Reduction in Plastic Consumption and Promote Reusable Alternatives:

The key to reducing plastic waste is to decrease plastic consumption in the first place. The Australian government can implement policies that incentivize the public to reduce their use of single-use plastics and promote the adoption of reusable alternatives. This can include educational campaigns highlighting the environmental impact of plastic waste and providing information on sustainable alternatives. Additionally, the government can offer tax breaks or subsidies to businesses that actively reduce their plastic consumption or switch to eco-friendly packaging.

Implement Plastic Bag Bans and Restrictions on Single-Use Plastics:

Following the lead of countries like Bangladesh, which implemented a plastic bag ban in 2002, and New York City, which banned plastic bags in 2020, Australia can introduce similar measures. Banning or imposing restrictions on single-use plastic bags and other disposable plastic items, such as takeout containers and beverage bottles, will significantly curb plastic waste. The government can also explore the idea of a plastics tax to discourage the use of plastic products.

Improve Recycling Infrastructure and Incentivize Recycling:

Recycling plastic is currently inefficient and expensive in Australia. The government should invest in advanced recycling infrastructure and technologies to improve the recycling process and create valuable new products from recycled materials. Additionally, providing financial incentives for individuals and businesses to recycle, such as refund schemes or discounts, can encourage more active participation in recycling programs.

Foster Collaboration Between Industries and Environmental Organizations:

The Australian government should facilitate partnerships and collaborations between industries, environmental organizations, and communities to develop innovative solutions for plastic waste reduction. This can include working with the private sector to design out waste, keep materials in use, and create a circular economy. For example, the government can provide grants or subsidies to businesses that incorporate recycled materials in their production processes or develop eco-friendly alternatives to plastics.

International Cooperation and Knowledge Sharing:

Plastic waste is a global issue, and Australia can benefit from collaborating with other nations and international organizations working to address plastic pollution. The country can learn from successful initiatives, such as the U.S. Agency for International Development's (USAID) Clean Cities, Blue Ocean program, which aims to reduce ocean plastic pollution in several countries. By sharing knowledge and best practices, Australia can develop more effective strategies and policies to combat plastic waste.

By implementing these comprehensive policies and strategies, Australia can make significant strides in reducing plastic waste, protecting the environment, and fostering a more sustainable future for its citizens.

Plastic waste environmental impact

Plastic waste is a pressing environmental issue in Australia, with far-reaching impacts. The country's plastic consumption has been steadily increasing, posing significant challenges to waste management systems and the environment.

One of the primary concerns regarding plastic waste is its persistence in the environment. Most plastics are designed for single-use purposes and are not biodegradable. As a result, they accumulate in landfills, roadsides, parks, and oceans, leading to unsightly littering and pollution. This pollution has severe consequences for wildlife, particularly marine ecosystems. Plastic waste can endanger marine life, and studies have also detected its presence in the food chain, ultimately reaching human plates.

The impact of plastic waste extends beyond pollution and littering. Plastics contribute to the growing waste stream in Australia, which has increased by almost 3% compared to 2018/19 levels. In 2020/21, Australia generated an estimated 75.8 million tonnes of waste, or 2.95 tonnes per person. While recycling and recovery efforts have been implemented, they have not kept pace with consumption. Only about 15% of plastic waste over the last 20 years has been effectively recycled, composted, or used for energy recovery. This inefficiency highlights the need for more effective policies and strategies to reduce plastic consumption and improve waste management.

The Australian government has recognized the urgency of the plastic waste crisis and has implemented various plans and policies to address the issue. These include the 2018 National Waste Policy, the 2019 National Waste Policy Action Plan, the Australian Packaging Covenant, and a goal to recycle or reuse 100% of plastic waste and end plastic pollution by 2040. Additionally, six out of eight states and territories have introduced laws to ban some of the most harmful and unnecessary single-use plastics. However, critics argue that these policies primarily focus on recovery and recycling rather than reducing plastic production and consumption.

To effectively tackle the environmental impact of plastic waste in Australia, a multifaceted approach is necessary. This includes continued support for recycling initiatives and infrastructure development, as well as a shift towards a circular economy. By reducing the use of single-use plastics, promoting reusable alternatives, and fostering markets for recycled materials, Australia can reduce its plastic waste footprint and mitigate the environmental consequences of this persistent form of pollution.
