Hydrometallurgical battery recycling with end-to-end material recovery

Fabricated Metal Products Aachen 51–200 employees Founded 2022 Privately Held

cylib operates a proprietary hydrometallurgical recycling process to recover lithium, graphite, nickel, cobalt, and manganese from battery packs and production scrap. The tech stack—dominated by industrial automation (Siemens TIA Portal, PLC, DCS, OPC UA) alongside Python, SQL, and IoT monitoring (InfluxDB, Grafana, MQTT)—reveals a company building physical infrastructure backed by data systems. Active hiring across engineering, manufacturing, and product (with senior-heavy seniority mix) maps directly to their project focus: commissioning a hydrometallurgical plant, designing control systems for hazardous environments, and scaling production quality.
