Master tinsmith Karl Theodor Rösle founded the original company in 1888. After his death in 1907, his sons ,Karl and Georg, took over Gebrüder RÖSLE KG. The current company name Grömo (since 2002) is an acronym for “Gebrüder Rösle Markt Oberdorf“.

Company structure

Grömo GmbH & Co. KG is a subsidiary of the company group Metallwarenfabrik Marktoberdorf. Also under this company umbrella: Rösle GmbH & Co. KG, one of the leading manufacturers and distributors of high quality, design orientated, non-electrical kitchen devices out of stainless steel. Both subsidiaries have their headquarters in Marktoberdorf.

Environmental protection/sustainability

Be green with Grömo! Grömo promotes its sustainability strategy which focuses particularly on efficiency. Take waste disposal, for example: the company has for many years been working with a service provider which organises and coordinates the collection of transport packaging from Grömo customers and then recycles this material in an environmentally friendly way. This successful dual system consistently recycles cardboard packaging, plastics and wood and this, in turn, saves precious valuable raw materials.

This measure is only part of the company’s increasingly environmentally friendly orientation – the strategic megatrend of sustainability and its main pillar, ecological sustainability, can be seen in all company areas as a management duty. This starts with an efficient use of materials and in-house electricity generation with photovoltaic installations and goes on to include the planning and realisation of new buildings according to complete energy saving concepts and waste disposal and recycling.
