The Plastic Plague: Decomposition Mystery Unveiled

Plastic is a material that does not decompose. It can take anywhere from 20 to 500 years to break down, and even then, it never fully disappears; it just gets smaller and smaller. In total, 8.3 billion tonnes of plastic have been produced, half of which has been produced in the last 13 years. Of this amount, 6.3 billion tonnes have become waste, with only 9% recycled and 12% incinerated. The remaining 79% ends up in landfills or in the environment, where it will stay forever in one form or another.

Plastic does not decompose

Plastics are defined as non-degradable, meaning they fail to decompose and are instead broken down into smaller and smaller particles. This process can take anywhere from 20 to 500 years, and even then, the plastic never fully disappears. For example, plastic bottles take an estimated 450 years to break down, while fishing lines take an estimated 600 years.

The production of so-called 'bioplastics' or biodegradable plastics is currently very low, estimated at around 4 million tonnes per year, which is just over 1% of global plastics production. Biodegradable plastic is typically defined as plastics that break down at faster rates than standard plastics. However, even biodegradable plastics do not fully decompose and can still contribute to plastic pollution.

Landfills, where much of the world's plastic waste ends up, can act as time machines, preserving plastic and other materials that would otherwise break down naturally. Even landfills that are left open and piled up tend to compact in on themselves, further preventing decomposition. As a result, plastic waste can persist in the environment for centuries, breaking down into microplastics that have been found in every corner of the globe, from Mount Everest to the Mariana Trench.

Plastic waste takes 20 to 500 years to break down

Of the 8.3 billion metric tons of plastic produced since the Second World War, 6.3 billion tons have become waste. Of this waste, only 9% has been recycled and 12% has been incinerated. The remaining 79% has ended up in landfills or in the environment, where it will stay forever in one form or another.

Some plastics are defined as non-degradable, meaning they fail to decompose and are instead broken down into smaller and smaller particles. Materials can slowly break down through photodegradation (from UV radiation). For example, fishing lines take an estimated 600 years to break down, while plastic bottles take an estimated 450 years.

The production of so-called 'bioplastics' or biodegradable plastics is currently very low, estimated at around 4 million tons per year (just over 1% of global plastics production). Biodegradable plastic is typically defined as plastic that breaks down at a faster rate than standard plastic. However, even biodegradable plastics do not fully disappear; they just get smaller and smaller.

79% of plastic ends up in landfills or the environment

It is estimated that 79% of plastic waste ends up in landfills or the environment. This is because plastic does not decompose. Instead, it breaks down into smaller and smaller particles, which can take anywhere from 20 to 500 years. Even then, it never fully disappears.

Since the large-scale introduction of plastic after World War II, a total of 8.3 billion metric tons have been produced. Of this amount, 6.3 billion tons had become waste by 2015. It is estimated that about 3% of all plastic produced every year ends up in the ocean.

The production of so-called 'bioplastics' or biodegradable plastics is currently very low, estimated at around 4 million tonnes per year (just over 1% of global plastics production). 'Biodegradable' plastic is typically defined as plastics that break down at faster rates than standard plastics. However, even biodegradable plastics do not fully disappear. They simply break down into smaller and smaller particles, which can be ingested by humans and other animals, potentially causing harm.

To prevent plastic from ending up in landfills or the environment, it is important to reduce plastic waste and increase recycling rates. Currently, only 9% of plastic waste is recycled, while 12% is incinerated. If the current trend continues, there will be about 12 billion tons of plastic in landfills and the environment by 2050.

3% of plastic produced ends up in the ocean

Plastic does not decompose. It takes anywhere from 20 to 500 years to break down into smaller and smaller particles, but it never fully disappears.

Since the large-scale introduction of plastic after the Second World War, a total of 8.3 billion metric tons have been produced. Of this amount, until 2015, 6.3 billion tons have become waste. It is estimated that about 3% of all plastic produced every year ends up in the ocean. This means that 249 million metric tons of plastic have ended up in the ocean since 1950.

The remaining 97% of plastic produced is either recycled, incinerated, or ends up in landfills. Only 9% of plastic waste is recycled and 12% is incinerated. The remaining 79% ends up in landfills or in the environment, where it will stay forever in one form or another.

If the current trend continues, around the year 2050, there will be about 12 billion tons of plastic in landfills and in the environment. This plastic will eventually break down into microplastics, which have been found in every corner of the globe, from the peak of Mount Everest to the trough of the Mariana Trench. Humans ingest an estimated credit card worth of plastic per week.

Biodegradable plastic makes up 1% of global plastic production

Plastic waste can take anywhere from 20 to 500 years to decompose, and even then, it never fully disappears; it just gets smaller and smaller. Of all the plastic waste that has been discarded so far, 12% has been incinerated, and only 9% has been recycled. The remaining 79% has either been disposed of in landfills or released into the environment.

The production of so-called 'bioplastics' or biodegradable plastics is currently very low: estimated at around 4 million tonnes per year (which would be just over 1% of global plastic production). This is because the vast majority of plastic is non-biodegradable and does not decompose.

Biodegradable plastic is typically defined as plastic that breaks down at a faster rate than standard plastic. However, it is important to note that even biodegradable plastic does not fully disappear. It just breaks down into smaller and smaller particles.

The world's production of plastic has increased significantly over the years, from two million tons in 1950 to 380 million tons in 2018. About half of all the plastic on Earth has been produced in the last 13 years. If the current trend continues, it is estimated that around the year 2050, there will be about 12 billion tons of plastic in landfills and in the environment.

It is clear that the production and disposal of plastic is a significant issue that needs to be addressed. While biodegradable plastic may be a small part of the solution, it is important to reduce plastic waste and increase recycling rates to mitigate the environmental impact of plastic.
