Tony Rehn, Program Director, Waste to Materials at Fortum highlights the company’s industry-leading developments in biodegradable plastic.
Leading waste management and circular solutions company Fortum Recycling & Waste has succeeded in producing biodegradable plastic from carbon dioxide (CO2) emissions through waste incineration at its plant in Riihimäki, Finland. This breakthrough, based on carbon capture and utilisation (CCU), is a significant step towards reducing and utilising industrial carbon dioxide emissions.
The production of CO2-based plastic is providing a new, sustainable raw material for the plastics industry.
“I am very proud that our team is the first in the world to successfully produce biodegradable plastic entirely from carbon dioxide emissions,” explains Tony Rehn, Program Director, Waste to Materials at Fortum. “This breakthrough is a significant step towards more sustainable plastic production. This kind of development work helps to reduce dependence on fossil-based raw materials and can create new circular economy-based business.”
Similar carbon capture development projects are underway in several industrial sectors in Finland and globally, but the majority of them focus on the production of synthetic fuels and carbon capture and storage (CCS).
“Captured carbon dioxide should be utilised as a new raw material instead of storing it underground or releasing it into the atmosphere when using fuel,” says Tony. “Utilising captured CO2 is a much more sustainable option in terms of tackling resource scarcity in the future. Whereas carbon capture and storage is a linear solution that does not address the growing material shortage, carbon capture and utilisation promotes circular economy.”
Fortum Recycling & Waste’s Carbon2x program piloted carbon capture and utilisation in 2022. The program aims to capture carbon dioxide emissions from the incineration of non-recyclable waste and use them to produce sustainable products, such as biodegradable plastic.
Plastic is a superior material due to its versatility
Every year, Europe generates nearly 100 million tonnes of non-recyclable waste that is incinerated and utilised in energy production. The wider implementation of the Carbon2x program’s innovation means that up to 90% of the CO2 emissions released into the atmosphere from waste incineration could be captured and bound into products.
New sustainable solutions are needed for plastic production to complement recycled and bio-based plastics. Biodegradable, CO2-based plastic offers a significant alternative to the market because it has the same qualitative properties as traditional, fossil-based virgin plastics.
“We want to promote the circulation of materials comprehensively,” says Tony. “We believe that a whole new category of sustainable plastics is emerging from products such as ours, even though the mechanical recycling of plastics is still needed.”
CO2-based plastic can be recycled just like many other plastics, closing the carbon cycle. An additional advantage of biodegradable plastic is that even if it did end up in nature by accident, it decomposes and does not leave harmful microplastics in the environment.
The Carbon2x program’s innovation is hoped to provide solutions not only for material production for food and cosmetics packaging, but also for other sectors such as toys and home electronics.
At this rate of development, the industrial production of biodegradable plastic made from waste incineration’s CO2 emissions could start as early as the end of the decade. The new ‘plastics born from CO2’ brand will be introduced to the European market in November 2024.
