Currently Röchling employs 11,988 people in 90 locations across 25 countries (North- and South America, Europe and Asia),[3] with annual sales of €2.723 billion in 2023.

In 1860, the newly opened rail line near the production site, as well as the addition of parts of Elsass and Lothringen to the German empire after the war 1870/71, contributed to the growth of the iron mill.

A military court sentenced Hermann Röchling in absentia to ten years in prison for dismantling French operations in the occupied territories.

[19] During the Second World War, the Saarland-based company produced weapons such as the "Röchling shell" in large numbers in its electric furnace facility.

[20] Because of industrial exploitation of the occupied territories, "increase of the war potential of the Third Reich and considerable role in the execution of the program of deportation for the purpose of forced labor,"[21] Hermann Röchling was sentenced by a French military court to a ten-year imprisonment plus asset expropriation in 1949 and was deprived of his civil rights.

[15] In 1956, following encouragement from chancellor Konrad Adenauer, the company bought arms manufacturer Rheinmetall Berlin AG, the equipment supplier of the newly founded Bundeswehr.

[10] Instead, the Röchling Group acquired holdings and complete companies in the fields of mechanical engineering, telecommunications, electrical installation, franking systems, measurement and control technology.

[31] Therefore, in 2001, Röchling decided on a fundamental change of strategy under the new non-family director Georg Duffner: abandonment of the conglomerate and further expansion of the business unit plastics processing.

[35][36] During the conversion to a plastic producer, all family members withdrew from the core business in accordance with the shareholders' resolution and moved to supervisory bodies.

[37][38] In 2001, Klaus Greinert, son-in-law of Richard Röchling and former managing director, joined the advisory board and became chairman of the family council.

According to a Handelsblatt article from 2004, the strong focus on plastics at that time also served to reduce debt and improve profitability as the Group's electronics sector was struggling.

[40] The process was completed in 2006,[41] when the last electronics company and a cold rolling mill were sold, which brought the Röchling Group a profit increase.

[41] Johannes Freiherr von Salmuth, a direct descendant of Friedrich Röchling in the sixth generation, took over as chair of the supervisory bodies: In 2008 (Shareholders' Committee) and in 2010 (Advisory Council).

His deputies are also two Röchling family members, Gregor Greinert (Shareholders' Committee) and Carl Peter Thürmel (Advisory Council).

[3] In Germany, the Röchling Group operates 26 locations: Arnstadt, Bad Grönenbach-Thal, Brensbach, Cologne, Haren, Ingolstadt, Lahnstein, Laupheim, Lützen, Mainburg, Mannheim, Munich, Nentershausen, Neuhaus am Rennweg, Peine, Roding, Ruppertsweiler, Rüsselsheim am Main, Stuttgart, Troisdorf, Wackersdorf, Waldachtal, Weidenberg, Worms, and Xanten.

[3][64] It supplies automotive manufacturers and system suppliers with plastic applications in the aerodynamics, propulsion, battery solutions, and structural lightweight sectors.

According to Röchling, declared goals are the reduction of emissions, weight and fuel consumption in the automotive industry, for which a restructuring of the division is planned.

It is financed by the start-up capital provided by the entrepreneurial family, by limited partnerships granted and inherited from shareholders in Röchling SE & Co. KG, investment income and cash donations.

[70] To this end, the foundation supports scientific research into new concepts for reducing plastic waste and improving recycling, as well as projects in sustainable development education.
