Converting climate damaging emissions into raw material

The chemical industry has long been exploring various ways of turning the carbon dioxide gas (CO2) into a useful raw material that can replace fossil feedstock and reduce the industry’s carbon footprint. Developing this technology is especially important for the plastics industry as most plastic is made from petroleum.

The CO2 gas has one thing in common with petroleum: it contains the element carbon, a central building block for the chemical industry, and, unlike petroleum, it is an abundant raw material. Covestro has been working with partners from industry and academia on a number of projects to capture CO2 and use it to replace petroleum.

The technology they have developed allows to use CO2 to produce a polyol, a main component of polyurethane foam, which is used almost everywhere – from furniture to building insulation.  The foam manufactured from this CO2-based polyol was first used in the production of mattresses. As a next step the polyol has been introduced as raw material in sports floorings. Most recently, the gas has found its way into car interior parts such as headliners and door panels. CO2 can also be used instead of oil to create insulating material for buildings and elastic fibres for stockings and other textiles.

In all its applications, the polyol used contains up to 20% CO2, replacing fossil fuels such as crude oil and reducing the amount of carbon dioxide in the air.

CO2 valorisation

Carbon is a crucial part of a large variety of products (e.g., from food we eat to the materials we use for everything) essential to our society. For Europe’s production to be more sustainable, we have to consider alternative carbon sources and production pathways. CO2 is an available carbon source with an abundant supply in Europe. Recycling carbon from CO2 can enable a more sustainable production of chemicals and materials. A European strategy towards CO2 emission reduction in a future circular economy should consider CO2 valorisation technologies.

Circular Economy 2.0

In 2015, the European Commission published its Circular Economy package to promote the transition from a linear economy into a circular economy, where resource efficiency is increased and the value of products and materials is maintained for as long as possible. When a product reaches the end of its life, options such re-use, remanufacturing and recycling can be explored to create additional value. Circular Economy can bring forth economic benefits, by contributing to growth and job creation and stimulating innovation, and in parallel provide environmental benefits.
