Type segmentation delineates the primary technological pathways used to reclaim materials from spent catalytic converters. Precious metal recovery focuses on extracting platinum‑group metals (PGMs) such as platinum, palladium, and rhodium through hydrometallurgical leaching, representing the highest revenue per tonne due to the intrinsic value of PGMs. Base metal recovery targets copper, aluminum, and steel, employing pyrometallurgical smelting or mechanical separation; while lower in unit price, this segment contributes volume stability because base metals constitute roughly 60 % of converter mass. Hybrid recovery combines both approaches, first separating bulk metals mechanically and then applying selective leaching for PGMs, optimizing overall yield and reducing processing waste. Collectively, these types shape the market’s cost structure and capacity planning, with precious‑metal‑centric operations driving the bulk of market size, while base‑metal and hybrid processes expand the addressable volume and improve sustainability metrics within the Automotive Catalytic Converter Recycling segmentation.
