New Strategies to Capture and Use CO2 as a Sustainable Carbon Source in the Synthesis of Value-Added Compounds

This work focuses on the development of sustainable strategies for carbon capture and utilization (CCU), a key technology for mitigating global warming by using CO₂ as a renewable carbon source.

Here we explored the role of quaternary ammonium salts in enhancing CO₂ capture and activation with NaBH₄. The presence of these salts resulted in both shorter reaction times and improved efficiency.

Synthesis of Lignin Nanoparticles Using CO2-Responsive Amines and Film Applications

The development of new lignin-based materials has become a very attractive alternative for researchers due to the particular properties that these can offer and their potential applications. Lignin is biosourced, abundant, biodegradable and renewable, for those reasons, it is an appealing feedstock from which to make materials for diverse applications in diverse fields. Lignin-based nanoparticles may offer properties and morphologies that differ from those of more conventional materials.

Supercritical CO2 Technology

Qarboon (ex-Dense Fluid Degreasing) specializes in sustainable, environmentally friendly industrial processes through its advanced supercritical CO2 technology. This technology is utilized in various applications, including the decontamination and sterilization of medical devices, bulk textile finishing, and degreasing/departiculation of mechanical parts using high-speed cleaning. Qarboon's machines are designed to be user-friendly, compact, and efficient, allowing for widespread accessibility.

Opus™ Platform for Sustainable Aviation Fuel

Twelve uses its Opus™ platform to transform CO₂, water, and renewable energy into hydrocarbons via CO₂ electrolysis. This is achieved using Membrane Electrode Assemblies (MEA), a CO₂-reducing catalyst that electrifies CO₂ and water while only producing oxygen, synthetic gas, and water. This synthetic gas is then used to produce Power-to-Liquid (PtL), Sustainable Aviation Fuel (SAF), and E-Naphtha™, the building block for CO2 Made® products.

Making chemicals from the air: the new frontier for hybrid electrosyntheses in artificial tree-like devices

Making chemicals from the air is a visionary objective that can potentially revolutionise chemical production. This critical review shows that the essential elements to realise this dream exist, even the many challenges, particularly in integrating all the components and operating them in synergy. The production of (i) fertilisers and (ii) food components (carbohydrates, proteins) from the air in artificial tree-like devices is analysed, focusing on the electrosynthesis aspects.
