The pressing challenge of climate change has spurred many innovative approaches to reduce greenhouse gas emissions, not only electrification. One promising strategy involves converting industrial waste gases into valuable consumer products. This concept aligns with SPIN’s commitment to closed carbon cycles. Unfortunately, regulations are still making it hard to implement such approaches.
A member company of SPIN is planning a production plant for synthetic, renewable jet fuel. The plant will be located next to a cement factory. This is in a country outside of the EU. The company faces over-strict EU regulations due to the Renewable Energy Directives. These regulations stop them from using some of the waste gases. These gases are massive amounts and unavoidable, emitted by the cement factory every day. Instead, they are now planning to import biogas from the next EU member state. This is the kind of nonsense that resulted from certain organisations’ lobbying campaigns for electrification and against eFuels. This approach totally ignores that we need to accelerate both if we want to meet our climate targets.
In contrast, a recent study led by Professor Jhuma Sadhukhan at the University of Surrey demonstrated the environmental benefits of repurposing CO₂ emissions. As part of the Flue2Chem initiative, researchers assessed the entire life cycle of converting waste gases from steel and paper mills. These waste gases were turned into chemical components (surfactants). Surfactants are used in everyday items like shampoos and detergents. The findings revealed a reduction in global warming potential by approximately 82% for paper mill emissions. There was nearly a 50% reduction for the steel industry compared to traditional fossil-based surfactant production.
This approach not only mitigates emissions but also fosters a circular carbon economy where waste becomes a resource. However, challenges such as high costs and limited hydrogen supply persist. The energy-intensive nature of these processes underscores the need for further investment in renewable energy infrastructure to make CO₂-derived products a cost-effective alternative.
SPIN is dedicated to advancing such sustainable practices, transforming industrial by-products into essential goods, and promoting closed carbon cycles for a more sustainable future.
