CS Tech Solution Limited (CS Tech) has introduced Hong Kong’s first carbon capture and utilisation (CCU) system.
By using pressure swing adsorption (PSA) technology from the UK with its own equipment, the system transforms industrial CO2 emissions into valuable resources, promoting a circular economy and reducing carbon footprints.
The system, which captures CO2 emissions from biochar production, could help reduce industrial emissions. “Amid the climate change crisis, the urgency to reduce emissions has become evident. Worldwide, extensive research is ongoing to explore various avenues for reducing carbon emissions, with a notable emphasis on carbon capture as a key focal point for future mitigation endeavours.,” stated CS Tech.
Unlike direct air capture, point source capture, as employed in this system, is more energy-efficient and cost-effective, making it particularly suitable for implementation in densely populated regions like Asia.
The captured CO2 is injected into concrete blocks via CS Tech’s proprietary system, permanently storing emissions while converting industrial waste into construction materials.
This process not only enhances the sustainability of the construction sector but also creates new opportunities for low-carbon intensity building products such as ready-mix concrete.
CS Tech is working with the Hong Kong Carbon Trading Centre (HKCTC) to develop methodologies for carbon credit certification. Through independent verification, carbon credits generated from the production of low-carbon construction materials can be traded on carbon markets.
“The reduced carbon emissions during the production of low-carbon intensity construction materials through carbon capture and utilisation technology can be accurately calculated,” noted CS Tech.
Hong Kong is actively pursuing carbon capture initiatives to achieve carbon neutrality by 2050. Veolia’s West New Territories Extension project, valued at over €2bn ($2.1bn), aims to process up to 90 million tonnes of non-recyclable waste over 20 years, ensuring a 90% methane capture rate to reduce the city’s carbon footprint. Hong Kong’s Climate Action Plan 2050 outlines strategies such as Net Zero electricity generation, energy-saving in buildings, green transport, and waste reduction, with carbon capture technologies playing a crucial role in these efforts.
