RETRON

What RETRON does

RETRON GmbH is a Lünen, Germany-based manufacturer of fireproof safety containers for lithium-ion batteries, operating as a wholly-owned subsidiary of REMONDIS Industrie Service GmbH & Co. KG within the REMONDIS Gruppe. The company designs and sells a six-tier product family — from the handheld 35-litre RETRON BOX for consumer electronics and E-bike batteries, through mid-size containers (RETRON 240/460/600, 155-489 litres) for trade and industrial users, to large-scale units (RETRON 750/4000, 671-3,900 litres) for hybrid-vehicle and EV battery logistics — built from hot-dip galvanised steel with a 30 mm thermal insulation layer that maintains exterior temperatures below 100°C even under 1,000°C internal fires for up to three days.

All RETRON containers are UN-certified and ADR-compliant for the transport of defective and end-of-life lithium batteries, feature tested pressure relief valves, integrated cable routing for in-box charging, and roll/stack/crane-transportable designs. The product line is paired with a complete service stack: container rental, ADR-compliant collection through partners like MIXX-TOUR, and environmentally compliant disposal routed through the REMONDIS recycling network, complemented by consulting, fire-protection concept development, and staff training.

RETRON serves B2B customers across trade (retailers, supermarkets, DIY stores, pharmacies, hotels, hospitals), municipalities (recycling centres, schools, public facilities), industry (automotive, manufacturing), and bicycle dealers, plus private households via the shop.retron.world e-commerce channel for the RETRON BOX. Revenue is generated through hardware sales, recurring container rental, professional disposal services, and consulting/training fees. The company is led by Managing Directors Robert Sonnenschein and Erik Silge, and benefits from REMONDIS's infrastructure spanning more than 1,500 locations across 30+ countries.

Expansion highlights6 records

Broad incumbents

• Veolia Environmental Services: Global environmental services and hazardous-waste management company. Comparable to RETRON (and its parent REMONDIS) on the disposal/recycling end of lithium-ion battery handling, but at vastly larger scale and across a much wider service portfolio.
• Stöbich Brandschutz: German fire-protection systems provider offering a broader portfolio (doors, curtains, storage) including solutions for lithium-ion battery fire containment. Operates in the same safety/regulatory space as RETRON but with a wider fire-protection portfolio rather than a focused battery-container niche.
• Justrite: North American safety container and storage manufacturer for flammable liquids and hazardous materials. Comparable industrial-safety product category and customer base, but broader portfolio and primarily US distribution rather than RETRON's EMEA focus.

Direct peers

• DENIOS: German-headquartered manufacturer of fire-resistant storage containers, safety cabinets, and hazardous-materials handling solutions, including a dedicated product line for lithium-ion battery storage and transport. Directly comparable to RETRON on product category, customer segments (industry, retail, municipalities), and certifications (UN/ADR).
• Düperthal Sicherheitstechnik: German fire-resistant safety storage specialist offering cabinets and containers for lithium-ion batteries and other hazardous materials. Direct competitor in industrial safety enclosures with comparable certifications and customer verticals.
• asecos: German manufacturer of safety storage cabinets for flammable and hazardous materials, including lithium-ion batteries. Overlaps with RETRON on safety enclosures for industrial and commercial users and on regulatory-driven demand.
• CEMO: German manufacturer of containers, tanks, and casks for hazardous materials and ADR-compliant transport. Shares RETRON's galvanized-steel construction, transport certification focus, and target customers in trade, industry, and emergency services.

Others

• REMONDIS: RETRON's parent company and one of the world's largest recycling, water, and service groups. Acts as a channel partner and end-of-life disposal service provider for RETRON; also a broader environmental services competitor to Veolia/Suez rather than a direct container competitor.
