Both processes are dependent on bacteria that consume and breakdown waste into simple matter. But PET is made with chemicals that bacteria cannot consume. That is not to say that plastics can't breakdown, they do, but it takes a long time; plastic bottles take up to 450 years to decompose in landfill.
How long does ocean plastic persist before decomposition?
450 yearsPlastic cups – 450 years The chemical bonds of plastic cups make them durable, but also resistant to breaking down. Overtime, these cups release toxic chemicals into the environment and are more likely to be ingested by vulnerable marine wildlife.
What is the fastest way to decompose plastic?
Additionally, how fast a plastic breaks down depends on sunlight exposure. Like our skin, plastics absorb ultraviolet (UV) radiation from the sun, which breaks down the molecules. This process is called photodegradation, and it's why landfills often expose plastic waste to the sun to accelerate the breakdown process.
How is plastic broken down in the ocean?
Plastic breakdown. Larger pieces of plastic in the sea or on land, such as bottles and plastic packaging, become brittle and gradually break down. This is due to sunlight, oxidation or friction, or by animals nibbling on the plastic.

The plastic material comprises of a wide range of semi-synthetic, synthetic and naturally occurring organic compounds that can be molded into usable objects. They are simply polymers made from repeating units.
Is it possible to clean up plastic waste?
Scientists argue that cleaning up plastic waste is not feasible and the debris are spread out into vast areas. Moreover, an ocean cleanup will not only cost extensively but also entails filtering of water that may catch plankton and other organisms which will disrupt the marine ecosystem. Moreover, 94% of the plastic waste end up on the seafloor.

What this means is that unless the petroleum-based plastic has been specifically designed to biodegrade, and although it may partially degrade, the plastic may last in the environment for tens to potentially hundreds of years, depending on the type of plastic and its disposal environment.
What is compostable plastic?
Plastic that is labeled as compostable is generally intended to be sent to an industrial or commercial composting facility which has higher temperatures and different breakdown conditions than those found in a typical homeowner’s compost bin.
Why are plastic bags banned?
With these objectives in mind, a number of communities are initiating bans of plastic bags that are intended for single use, such as those commonly provided in grocery stores. The rationale behind the bag bans includes the following: 1 They are typically made out of petroleum-based plastic and don’t biodegrade when they are disposed of or escape into the environment; 2 when plastic bags are disposed of on land they may be blown into creeks, lakes, or oceans where they can entangle marine life or the animals may mistakenly eat the plastic bags thinking that they are food; 3 the light-weight plastic is not easily recyclable; and 4 the bags are often used only once before being thrown away.
Why are degradable claims deceptive?
Unqualified degradable claims for items that are customarily disposed in landfills, incinerators, and recycling facilities are deceptive because these locations do not present conditions in which complete decomposition will occur within one year.". 1. Plastics are derived from organic products.
How is plastic made?
The production of plastic begins with a distillation process in an oil refinery involving the separation of heavy crude oil into lighter groups called fractions. Each fraction is a mixture of hydrocarbon chains (chemical compounds made up of carbon and hydrogen), which differ in terms of the size and structure of their molecules.
What are the two processes used to make plastic?
The two major processes used to produce plastics are called polymerisation and polycondensation, and they both require specific catalysts. In a polymerisation reactor, monomers like ethylene and propylene are linked together to form long polymers chains.
