Techno-economic data for technology yields (γ) used in the model was obtained using Ecoinvent 3.5 life cycle inventory and literature. The processing cost (α tc t ) for each technology was estimated based on the price difference between the input and output products, with consideration on the yields. The prices of all the products (including feedstocks, intermediate chemicals, and final products) are collected through either public websites or literature. The data for minimum demand requirements (d k ) of the final products is obtained from the literature. The data for maximum supply capacities (s i ) of feedstocks was obtained from public electronic sources or literature. Life cycle assessment (LCA) data, including metrics such as the global warming factor and land use, were obtained from the Ecoinvent 3.5 database. We use the software, openLCA v1.10.3, as the platform for calculating LCA impacts. For products that are not present in the Ecoinvent 3.5 database (mostly for the biomass-derived chemicals), their inventory data is obtained based on material balance information from the literature. The LCA impact analysis is performed by using the ReCiPe 2016 Midpoint (H) method. The LCA impacts for all the materials are based on cradle-to-gate analysis. We adopt a similar approach to assess the LCA impacts of the technologies in the model as we estimate the processing cost. The LCA impacts of the technologies were estimated as the differences between the LCA impacts of input and output materials. The detailed data associated with TEA and LCA are provided in the supporting information (SI) and at https: //github.com/zavalab/JuliaBox/tree/master/Plastic_pathway.
