What Sesotec does

Sesotec GmbH is a privately held German industrial technology company founded in 1976 and headquartered in Schönberg, Lower Bavaria. The company develops and manufactures inspection and material sorting equipment used by food processors, plastics manufacturers and compounders, and recycling operators. Its product portfolio spans four hardware families (inductive metal detectors, X-ray inspection systems including the RAYCON line with THiNK Technologies, magnetic separation systems, and optical sorting systems) plus software and AI-driven material analysis platforms such as OBJECT-AI, FLAKE PURIFIER+, FLAKE SCAN, and the recently launched PRE-SORT mobile sorting platform.

The company sells bespoke industrial equipment through a direct enterprise field-sales motion with consultative selling, supported by 18 global locations including showrooms, a wholly-owned Netherlands subsidiary, and a Malaysia production facility for Asian markets. Revenue is generated primarily through one-time equipment sales, supplemented by recurring aftermarket services (installation, commissioning, maintenance contracts, spare parts, remote support, training) and a Sesotec App for ongoing customer engagement.

Sesotec has been named a key player in Europe recycling sorters (35% European market share referenced in industry reports) and operates across three primary verticals: food processing (foreign-body detection and HACCP/IFS/BRC compliance), plastics manufacturing and recycling (regrind quality, food-grade rPET), and general recycling (municipal waste, glass, e-waste, lithium-ion battery fire prevention via the WeSort.AI partnership). Customer logos span Backwelt PILZ, SITRAPLAS, Mission PET, Reiling Glas Recycling, Steinbeis Polyvert, Bachmann Group, and Coppa Inc. The company has won multiple awards including Top Company (Kununu, five consecutive years), TOP 100 Innovator (Compamedia), and Product of the Year 2025 in Recycling (PRE-SORT).
