The Billigheim Hazardous Waste Landfill

HIM operates a landfill for the disposal of hazardous waste at the Billigheim location in the Neckar-Odenwald district (northern Baden-W?rttemberg). The facility is owned by the state of Baden-W?rttemberg.

Commissioned in 1984, the landfill is going to be filled up to the planned volume thanks to state-of-the-art adaptations.

The location and characteristics of the facility, multiple underground and surface sealing systems and the proper operation of the installation with regulated control and maintenance processes assures that the Billigheim hazardous waste landfill is safe and environmentally compatible.

Overview of the Billigheim hazardous waste landfill:

Total landfill volume:Approx. 930,000 m3
Filled volume (as of December 2006):Approx. 580,000 m3
Remaining volume:Approx. 350,000 m3
Remaining capacity:Approx. 525,000 t


Disposal Process

Disposal is more than just the storage of waste. In the Billigheim hazardous waste landfill, we treat the supplied materials with due diligence, disposing of them properly and safely in the best interests of our customers and the environment. The typical disposal process includes the following steps:


Waste is classified based on customer-specific information. HIM prepares the analyses needed for disposal and obtains the required official confirmations.



The material is weighed; the certificate of disposal and supply note or dock receipt are checked.



The analysis results are compared to the data in the certificate of disposal and the facility limits before the delivery is approved.


In order to avoid contamination, the vehicles only drive on landfill roads constructed for this purpose. The waste lots are deposited in established grid squares.


Before leaving the landfill, the tyres of delivery vehicles are cleaned in order to exclude the dispersion of hazardous substances. A confirmation of proper disposal is issued.



Waste Catalogue

Landfill Wastes

Inorganic wastes from galvanising, metal processing and industrial waste water treatment account for the bulk of the hazardous waste deposited in Billigheim.

Selection of landfill wastes:

  • Industrial waste water treatment residues
    (filter cake, galvanic sludge)
    • blasting grit
      • Asbestos waste
        • Contaminated soil and rubble
          • Slag from thermal processing
            • Batteries
              • Contaminated packaging

                Waste for the Transshipment Installation

                The transshipment installation accepts wastes that cannot be deposited in the Billigheim hazardous waste landfill. These wastes are transferred to suitable disposal or recycling facilities for further treatment. They include expired lacquers and paints, lacquer sludge, workshop waste, filters and absorbent materials.

                The Base Seal

                Several complementary systems in accordance with the multi-barrier principle are used to protect the soil and groundwater at the Billigheim hazardous waste landfill. Clay absorbs reaction forces, equalises deformation and settling and is effective for the retention of hazardous substances. The plastic sealing layer blocks and is resistant against leachate.

                With proper depositing, compliance with assignment criteria and the inspection of all deposited wastes, a stable landfill is created that binds hazardous substances and reduces the generation of leachate.

                Leachate is collected and extracted from the landfill through a drainage system with a length of almost 5 km. Proper drainage largely keeps the landfill dry, thereby preventing the release of hazardous substances.

                The Surface Seal

                Once a section of the landfill has been filled to capacity, the surface is also sealed. The combination seal which, like the base seal, consists of plastic film and clay, prevents precipitation from getting into the landfill. Rainwater does not come into contact with wastes and can be drained without the need for treatment.
                The surface seal along with the systematic extraction of leachate through the drainage system ensures that waste stored in the landfill dries out. This prevents hazardous substances from being washed out into the soil and groundwater.

                The drainage system, surface and base seal are continuously monitored and carefully maintained. Once the landfill operation is closed, the maintenance phase with ongoing landfill, groundwater and leachate monitoring and treatment begins.

                Maintenance continues until leachate ceases to develop. At this time, a maintenance phase of approximately 30 years is expected.

                The Leachate Treatment Plant

                The leachate from the landfill and water from the tyre cleaning plant are separately collected and treated in a dedicated waste water treatment plant.

                Dual-stage nitrification and denitrification constitutes the first phase of waste water treatment. Microorganisms largely break down organic substances and nitrogen compounds. In the next treatment step, the bacteria are separated and returned to the treatment cycle. An ion exchanger removes dissolved metals from the water in the third step before it is finally passed through a multi-stage activated carbon adsorption plant that removes the remaining organic compounds.

                Waste water treated in this manner is transferred to the public sewer system through a dedicated line and then to a sewage treatment plant. The water discharged by the leachate treatment plant is continuously monitored by us. Waste water samples are also analysed by an independent laboratory at regular intervals.

                Facility Maintenance

                The hazardous waste landfill drainage system is cleaned with a high-pressure cleaning system once a year and then inspected by remote camera. This allows the condition and functionality of the drainage system to be verified and any changes to be recorded.

                The base seal is verified by analysing the settling behaviour of the drainage lines. In order to do so, a highly sensitive altimeter is used to inspect the drainage lines. The elevations of the drainage lines measured in this way are fed into a calculation model along with the deposited waste quantities and settling is compared to the theoretical deformation values calculated in advance.

                The surface seal is a key element to permanently protect the environment from the deposited wastes. This is why the surface seal is made of several layers so that the plastic sealing membranes can be inspected. Inspection openings or gauges around the edges are used for inspection.









                Environmental Monitoring

                A system of 34 groundwater gauges or wells is used for groundwater monitoring. The measurement points are arranged in several circles within the upstream and downstream groundwater system, ranging from locations in the vicinity of the landfill up to 2 km away. Groundwater quality is verified and documented through regular sampling and analysis. No impact on groundwater from the landfill has been noted.

                Air quality at the perimeter and in the vicinity of the Billigheim hazardous waste landfill is monitored using standardised plant cultivation, so-called bio-monitoring. The cultivation of special strains of grass, kale and lichens is used to identify the impact of the landfill on air quality. Grass cultivation is used to monitor heavy metals, kale to identify specific organic compounds (polychlorinated biphenyls and polycyclic aromatic hydrocarbons). General air quality is monitored by observing the condition of the lichens.

                Agricultural products and feed grown in the immediate vicinity of the landfill are analysed every year.

                A meteorological measurement station continuously records climate data including the wind speed, wind direction, temperature and precipitation.
