The efficient use of resources and the utilization of generated waste within a circular system are essential for a sustainable future. Audi Hungaria’s flagship resource‑efficiency project, the Aluminium Closed Loop, was launched in 2021. At that time the company integrated the aluminum used in production into a closed‑loop system. The core of the closed loop is that aluminum waste generated during production, after being selectively collected by alloy, is returned to the supplier, who produces aluminum coils of identical quality and delivers them back to Audi Hungaria as raw material.

Within the Aluminium Closed Loop, the use of non‑renewable natural resources is significantly reduced by utilizing aluminum waste of consistently high quality as a secondary raw material. Recycling without quality degradation (downcycling) helps vehicles enter the use phase of their life cycle with a more favorable environmental footprint. Producing aluminum as a secondary raw material reduces energy consumption by 95 percent compared with primary production.

Geothermal energy is our energy: Audi Hungaria covers a significant proportion of its thermal energy requirements with the help of geothermal energy. Since 2012, a geothermal energy plant has been in operation, which provides more than 70 percent of the site's thermal energy requirements. The output of this plant makes our company the largest industrial geothermal energy consumer in the whole of Hungary. The plant provides Audi Hungaria with at least 82,000 megawatt hours of thermal energy per year. Since we have been able to put geothermal energy at the service of our company, we have avoided the emission of more than 18,000 tons of carbon dioxide every year. We offset the remainder of our heating energy requirements with biogas certificates.

The dry separation process using stone powder, applied in car body painting, is an energy- and water-saving technology. This method leads to a substantial decrease in VOC emissions. 

Ecological diversity is very important to us: To preserve biodiversity, Audi Hungaria therefore joined the "we4bee" initiative in May 2021, which is supported by the Audi Environmental Foundation. As part of this project, we expanded our own beekeeping facilities on the factory premises to include a beehive equipped with high-tech sensors. These sensors are used to record a wide range of data on temperature, humidity, air pressure, weight, vibration and fine dust pollution. The program aims to compare around 100 smart beehives, most of which are located in Germany, using the data collected. This allows scientists to study the pollination behavior of bees and the effects of the environment on bee colonies. The researchers' aim is to support the work of beekeepers in the short term. In the long term, the behaviour of insects should even make it possible to predict environmental events such as storms or earthquakes.

In Audi Hungaria's disposal logistics, Büchl Hungaria uses an e-truck to transport aluminum waste within the aluminum closed-loop process between Audi Hungaria and an external interim storage facility.

This waste-logistic solution enables savings of approximately 40 tons of CO2 emissions per year.

A dedicated charging station for the e-truck was built on the factory site, allowing the technical waiting times in the press shop to be efficiently used for charging the vehicle.

An innovative technology for recycling rubber waste: thanks to the cooperation between AUDI HUNGARIA Zrt. and NEW ENERGY Kft., rubber waste generated at the Győr site is processed through chemical recycling, thereby preventing microplastics and associated pollutants from entering the environment during recycling. The process applied is pyrolysis. During the process, rubber is converted into oil through chemical recycling, which is used by petrochemical companies to produce new plastics, while the resulting industrial carbon black is utilized in tire manufacturing. The gases generated during pyrolysis are used to produce the high temperatures required for the process.
