WITH CONVINCING RESULTS
With continuous improvements and numerous projects, such as new heat treatment plants or pilot projects for the use of waste heat from the melting furnaces, we are already achieving significant savings in our energy requirements. We are continuously working on projects that increase energy efficiency and reduce CO2e emissions. The same applies to the environment: here, too, we are continuously working to reduce our water consumption and avoid waste.
We present two sustainability projects below that have already been implemented:
1. Energy project – generating electricity in-house
We produce our own electricity using our combined heat and power plant in Mexico and our photovoltaic systems in Germany and Switzerland.
Our recent photovoltaic projects have been completed at our production facilities in Jičín, Czech Republic, and Teruel, Spain.
The photovoltaic system at the Jičín site was installed on the roof of the dispatch warehouse and went into permanent operation at the beginning of 2025. The electricity generated is entirely used for the plant’s own needs, ensuring a more sustainable energy footprint without feeding into the public grid. The project received funding support from the European Union and the Ministry of Industry and Trade of the Czech Republic, which contributed 35% of the delivery and installation costs.
At our Teruel plant, a large-scale photovoltaic system was constructed between August and November 2024, covering an impressive 60,000 m²—equivalent to 10 football fields. Featuring 8,000 bifacial solar panels that capture both direct and reflected sunlight. The system was fully commissioned by the end of 2024 and marks a significant step in improving our carbon footprint.
2. Environment project – focus on waste and water
During the manufacturing process of our wheels, various types of waste are generated, including aqueous waste. An ongoing pilot project uses evaporation technology to allow the water present in the waste to evaporate, thus reducing the volume of waste. In the future, it will be possible to use the distilled water again in production by condensing the resulting water vapor.
This has already reduced waste by 75% (cooling lubricants and water with greases) and cut disposal costs.
3. RONAL IBÉRICA sustainability improvement plan
RONAL IBÉRICA SAU has developed the project with file number 23/032-002, with the objective of improving the sustainability of the company through actions that improve energy efficiency and increase the level of environmental protection and which has been supported in the call of aid for business investment projects that promote an environmentally sustainable economic model in the province of Teruel subsidized by the Government of Spain and the Government of Aragon from the Teruel Investment Fund, for an amount granted of € 1,451,426.79.
