Unlocking The Carbon Storage Mystery In Waste Plastics

Plastic waste is a significant contributor to global warming and climate change. The carbon footprint of plastics is surprisingly carbon-intense, with the production, transportation, dumping, incineration, recycling and composting of plastics all releasing carbon dioxide. In 2015, the global emissions from incinerating plastic packaging totalled 16 million metric tons of CO2e. Every ton of plastic waste in landfills releases about 3 tons of carbon dioxide equivalent (CO2e) greenhouse gas emissions.

Plastic waste in landfills releases carbon dioxide equivalent (CO2e) greenhouse gas emissions

The carbon footprint of plastics continues even after we've disposed of them. Dumping, incinerating, recycling and composting (for certain plastics) all release carbon dioxide. In 2015, the global emissions from incineration of plastic packaging, which represents 40% of plastic demand, totalled 16 million metric tons of CO2e. The emissions from plastics in 2015 were equivalent to nearly 1.8 billion metric tons of CO2. Researchers expect this number to grow, projecting that the global demand for plastics will increase by some 22% over the next five years.

By one estimate, emissions from producing and incinerating plastics could amount to 56 gigatons of carbon between now and 2050. This is almost 50 times the annual emissions of all the coal power plants in the US.

However, four global policies could eliminate more than 90% of plastic waste and 30% of linked carbon emissions by 2050.

Plastic waste in oceans

Plastic waste is a major contributor to global warming and climate change. The carbon footprint of plastics is surprisingly intense, with emissions from producing and incinerating plastics projected to amount to 56 gigatons of carbon between now and 2050. This is almost 50 times the annual emissions of all the coal power plants in the US.

Every ton of plastic waste in landfills releases about 3 tons of carbon dioxide equivalent (CO2e) greenhouse gas emissions. Several million tons of plastic waste enter the oceans each year, with plastic packaging alone accounting for 16 million metric tons of CO2e in 2015.

The overwhelming majority of plastic resins come from petroleum, which requires extraction and distillation. The resins are then formed into products and transported to market, with all of these processes emitting greenhouse gases. The carbon footprint of plastics continues even after disposal, as dumping, incinerating, recycling, and composting (for certain plastics) all release carbon dioxide.

Four global policies could eliminate more than 90% of plastic waste and 30% of linked carbon emissions by 2050. These policies aim to address mismanaged plastic waste, which refers to plastic that isn't recycled or properly disposed of and ends up as pollution.

Plastic alternatives

Plastic waste is a major contributor to global warming. Every ton of plastic waste in landfills releases about 3 tons of carbon dioxide equivalent (CO2e) greenhouse gas emissions that contribute to climate change. Several million tons of plastic waste enter the oceans each year.

Plastics have carbon-intense life cycles. The majority of plastic resins come from petroleum, which requires extraction and distillation. Then the resins are formed into products and transported to market. All of these processes emit greenhouse gases, either directly or via the energy required to accomplish them. The carbon footprint of plastics continues even after we've disposed of them. Dumping, incinerating, recycling and composting (for certain plastics) all release carbon dioxide.

When it comes to plastic alternatives, there is often an emphasis on carbon emissions, but other important factors include end-of-life impacts, the extraction of raw materials, water and land use, and the release of hazardous chemicals. Simply replacing disposable plastic with another material will not reduce the burden on the environment. The least problematic solution is reusable and refillable packaging and buying unpackaged.

There are also some biodegradable alternatives to plastic. Plant-based plastics, known as bioplastics, have been hailed as a green alternative to fossil fuel-based plastic, especially when it comes to food packaging. One type of bio-based and biodegradable plastic alternative is PHA, or polyhydroxyalkanoates. PHA is produced by microorganisms through bacterial fermentation fuelled by a variety of plant sources. Genecis is a company which uses food waste and agricultural waste to feed their bacterial cultures, resulting in a truly circular manufacturing process. Refork, a Czech company specialising in eco-friendly cutlery, straws, and toothbrushes, uses wood fibre mixed with PHA polymer and minerals in their production. Biodegradable algae-based packaging is another promising alternative to plastic. B’zeos, a Norwegian startup, was the first company to use seaweed to develop sustainable packaging. Since introducing their first product in 2018, an edible drinking straw, the company has expanded to produce biodegradable condiment packets, cutlery, and plastic wrap, all of which are designed to biodegrade completely in less than 47 days.

Plastic packaging

Every ton of plastic waste in landfills releases about 3 tons of carbon dioxide equivalent (CO2e) greenhouse gas emissions that contribute to climate change. Several million tons of plastic waste enter the oceans each year, with global emissions from the incineration of plastic packaging totalling 16 million metric tons of CO2e in 2015.

The overwhelming majority of plastic resins come from petroleum, which requires extraction and distillation. The resins are then formed into products and transported to market, with all of these processes emitting greenhouse gases, either directly or via the energy required to accomplish them.

The carbon footprint of plastics continues even after we've disposed of them. Dumping, incinerating, recycling and composting (for certain plastics) all release carbon dioxide. Researchers expect the emissions from plastics to grow, with global demand for plastics projected to increase by 22% over the next five years.

Plastic waste that isn't recycled or properly disposed of

The emissions from plastics are substantial, with global emissions from plastic packaging incineration alone totalling 16 million metric tons of CO2e in 2015. Every ton of plastic waste in landfills releases about 3 tons of carbon dioxide equivalent (CO2e) greenhouse gas emissions, contributing to climate change. This is further exacerbated by the millions of tons of plastic waste that enter the oceans each year, polluting the marine environment and impacting marine life.

The carbon footprint of plastics is not limited to the waste itself but also includes the emissions associated with its production and incineration. By one estimate, emissions from producing and incinerating plastics could amount to 56 gigatons of carbon between now and 2050, highlighting the urgency of addressing plastic waste.

To mitigate the environmental impact of plastic waste, effective waste management strategies are crucial. This includes reducing plastic consumption, improving recycling practices, and implementing policies to minimise plastic waste. According to a study, four global policies could eliminate more than 90% of plastic waste and 30% of linked carbon emissions by 2050, demonstrating the potential for significant improvement.
