This techno-economic report reviews the chemistry and process technologies for general purpose polystyrene (GPPS), high impact polystyrene (HIPS), expandable polystyrene (EPS), and syndiotactic polystyrene (SPS). Processes from major technology developers are presented. Cost of production economics are presented for different GPPS, HIPS, and EPS processes for USGC, China, and Western Europe locations. Demand by end-use, capacity, and supply/demand/trade data is provided for global and major regional markets.

This report provides an analysis of cellulosic biofeedstocks and the costs of producing them.  A capacity analysis including regional and feedstock specific potentials for production are included. Impacts on the conventional industries includes comparisons to the scale of petroleum based energy and chemicals, costs, and carbon intensity.

This report provides a techno-economic analysis of key biomass pyrolysis technologies. The background and the process description for relevant technologies are described and their comparative economics are presented. A risk-adjusted capacity listing is provided and the implications of these technologies on the conventional energy, fuels and chemicals industries are explored.

EPDM is produced by the polymerization of ethylene, propylene, and typically another monomer containing side-chain unsaturation such as ethylidene-5-norbornene-2 (ENB). It is produced by Ziegler-Natta or metallocene (includes single site or similar catalyst types) catalyzed solution processes, or a Zeigler-Natta catalyzed slurry process. EPDM has a fully saturated molecular backbone that provides excellent ozone resistance, weatherability and heat resistance properties, very good dielectric performance, and low temperature flexibility. This report includes an analysis of EPDMs markets, end-uses, and production technologies. Production economics were prepared for world-scale Ziegler-Natta solution, Metallocene solution, and Ziegler-Natta slurry processes. The economics were prepared for plants located in the U. S. Gulf Coast, Western Europe, and China Coast.
