Co-refining is emerging as a strategic approach in the energy and refining industry, enabling conventional refineries to process renewable and fossil-based feedstocks together. By integrating bio-based oils, waste-derived feedstocks, or synthetic intermediates into existing refining infrastructure, co-refining supports the transition toward lower-carbon fuels without requiring entirely new facilities. This approach offers refiners a practical pathway to improve sustainability while maintaining operational efficiency and product quality.

One of the key advantages of co-refining is its flexibility. Refineries can blend renewable inputs such as used cooking oil, animal fats, or bio-oils with crude oil streams, producing transportation fuels that meet regulatory standards. This flexibility allows refiners to respond quickly to changing market demands, fuel regulations, and carbon reduction targets. Additionally, co-refining leverages existing assets, reducing capital expenditure compared to standalone bio-refineries.

From a sustainability perspective, co-refining plays a vital role in reducing greenhouse gas emissions. By partially replacing fossil feedstocks with renewable alternatives, lifecycle emissions of fuels can be significantly lowered. This supports compliance with renewable fuel standards, low-carbon fuel initiatives, and net-zero commitments adopted by governments and corporations worldwide.

Technological advancements are further accelerating co-refining adoption. Improvements in catalyst design, process optimization, and feedstock pre-treatment have enhanced compatibility between renewable and fossil inputs. These innovations help maintain refinery reliability while ensuring consistent fuel performance.

As energy systems evolve, co-refining is expected to act as a bridge solution—supporting decarbonization today while paving the way for future fuels such as sustainable aviation fuel and synthetic hydrocarbons. Its ability to combine economic viability with environmental benefits positions co-refining as a critical element of the global energy transition.
