Waste

In the manufacture of products, as well as in the performance of production processes and other activities, attention is paid to environmentally sound waste management. A particular focus is placed on disposal of hazardous waste (such as used oil, emulsions, workshop waste and filter dust) in compliance with statutory requirements. Waste law managing directors have been appointed for the collection of hazardous waste, and individuals have been appointed with responsibility for non-hazardous waste. Waste officers are responsible for monitoring compliance with waste legislation, and are required to report to management in this capacity. Waste is recorded entirely according to waste type and volume for the purpose of traceability in accordance with the Waste Documentation Ordinance, and is handed over to licensed companies for disposal and treatment within the framework of the legal provisions.

Management

Waste is recorded entirely according to waste type and volume for the purpose of traceability in accordance with the Austrian Waste Documentation Ordinance, and is transferred to licensed companies for disposal and treatment within the framework of the legal provisions.

 

As part of the smelter operation at the Ranshofen site, which was discontinued in 1992, various types of waste were sent to a landfill. AMAG continuously implements the aftercare of the landfill, which is recorded in the register of contaminated sites. The leachate produced in the landfill is treated on the plant premises, and the groundwater in the vicinity of this landfill is monitored at regular intervals.

 

The company is also aware of other former landfills that are included in the register of potentially hazardous sites. In addition, AMAG owns a disused landfill in Furth im Walde, Germany, which is now in the renaturation stage.

 

AMAG is required to submit annual reports to the relevant authorities on the environmental state of the site and precautionary measures taken. Salt slag is the most significant type of waste in terms of volume at AMAG.

 

The recycling of contaminated scrap requires the application of special salts to provide protection against oxidation and to remove and separate the oxidic and non-metallic contaminants. This generates salt slag, all of which is recycled by specialist companies. Delivery to the recyclers is by rail. As a consequence, no waste is left over for disposal after processing. The oxidic residue is utilised in the cement industry, for example.

Targets

Target 2021: 

  • Avoidance or reduction of waste; production-specific waste volume < 16 kg/t

Central measures:

 

Construction of the new intermediate waste storage facility, including a new hall to improve waste management, was completed in 2021. This is where waste is centrally weighed and digitally recorded according to type, quantity, origin and location. The incoming inspection of delivered waste also takes place there. In the 2021 reporting year, work began on renewing more than four kilometres of the siding’s railway track sleepers, replacing more than 6,000 wooden sleepers with concrete sleepers.

 

The factory premises are connected to the public rail network through an extensive internal rail infrastructure. Choosing concrete is a sustainable approach, as wooden sleepers must be disposed of as hazardous waste due to tar constituents. This significantly extended the life of the rail network and took the importance of rail transport into consideration.

 

The use of washable and consequently reusable cleaning cloths instead of disposable materials represented a further waste reduction measure. Alternative disposal methods were evaluated for improved filter dust disposal. In addition, investigations of suspected contaminated sites at the Ranshofen site were carried out on behalf of the Austrian Environment Agency. Initial sampling was conducted and further investigation was determined based on the report of findings from the Environment Agency Austria. These will be implemented in 2021 and 2022.

 

2022 target / medium term:

  • Avoidance or reduction of waste; production-specific waste volume < 16 kg/t at the integrated Ranshofen site
Results

Results:

 

The volume of waste generated in 2021 at the Ranshofen site amounted to 9,750 tonnes (2020: 9,100 tonnes), of which 4,950 tonnes were classified as hazardous and 4,800 tonnes as non-hazardous.6 In the process, 69 % of the non-hazardous waste (e.g. waste wood, iron and steel waste) was recycled and 31 % disposed of. Of the hazardous waste (e.g. used oil, filter dust), 7 % was recycled and 93 % disposed of.

 

AMAG components generated a total of around 400 tonnes of waste.

 

Specific waste volumes in relation to production volume amounted to 15.5 kg/t in 2021 (2020: 16.6 kg/t).

 

The figures do not include:

  • Scrap metal generated during production, as this is recycled and returned to the internal materials cycle
  • Construction waste at the plant site that is reutilised as recycled building material
  • Waste from construction activities (such as construction and demolition wood, construction rubble, concrete demolition, contaminated soils)
  • Salt slag
