English
This paper analyzes patent filings from 2018-2024 to examine innovation in alternative chemical feedstocks, focusing on plastic waste pyrolysis and carbon capture and utilization (CCU). It finds that waste-derived hydrocarbon patents are growing faster than conventional refining patents, and digital-enabled CCUS patents are expanding rapidly. However, constraints such as waste collection infrastructure, low-carbon hydrogen availability, and electricity costs remain significant barriers to deployment.

📄 Abstract（原文）
The chemicals industry remains structurally dependent on fossil-derived feedstocks, even as efforts to reduce operational emissions continue. This paper provides patent-based evidence on innovation in alternative feedstock pathways, focusing on plastic waste pyrolysis and carbon capture and utilization (CCU). Using priority patent filings from 2018–2024 and publicly available production data,4 we compare growth in waste-derived hydrocarbons and CO2-based chemical conversion with that of conventional fossil-based hydrocarbon production. Our analysis shows that patent filings in waste-derived liquid hydrocarbons have grown more rapidly than filings associated with refining technologies. Carbon capture patents that incorporate digital technologies have also expanded at higher rates than carbon capture patents overall. Despite this acceleration, structural constraints remain significant. Pyrolysis depends on waste collection infrastructure and feedstock consistency, while CCU deployment is closely tied to low-carbon hydrogen availability and electricity costs. Although our research highlights the growing emphasis on upstream carbon substitution, economic and infrastructure conditions will shape the scale of adoption of these technologies.
