Ecologically and economically viable

Landfill mining with ALLRECO plant expertise: Robust and flexible technology for a profitable procedure.

Landfill mining

The landfill mining topic is getting more and more relevant – whether to create new building areas and remediate soil and water in urban agglomerations or to recover waste materials for material or energetic recovery.

With robust and powerful machines ALLRECO sets new standards in the landfill mining pursuing ecological and commercial goals and combining them with a lot of experience to meet the requirements on site.

Usually landfill mining is used to make future building or landfill areas available and to recover secondary raw materials such as ferrous and non-ferrous metals.

  • Fuels
  • Soils, cover material
  • Raw materials (e.g. metals)

The benefits of ALLRECO machines in the landfill mining:  

  • Robust procedure for very  heterogeneous material
  • Profit from larger landfill capacity
  • Profit from building area for other purposes
  • Energetic and material utilization of some of the landfill materials
  • Including ALLRECO service and quality

Process Description Landfill mining

Landfill mining pursues ecological and commercial goals. On the one hand, it is used to remediate soil and ground water. On the other hand, important raw material and recyclable material fractions can be recovered by means of landfill mining. Both material and energy recovery of the material fractions are possible after the processing thus making an important contribution to profitability.

The process is composed of a spiral shaft separator (Splitter UNIT) to grade the landfill material. From the resulting coarse and fine fractions, a magnet separates iron. Depending on its properties, the coarse fraction can be recovered energetically, reinstalled or further processed with a windsifter. The fine fraction is screened with a second mesh size by means of a trommel screen. The oversize is density-separated in a windsifter. The resulting light fraction can be utilized energetically. The heavy fraction can be reinstalled or transferred to a building rubble processing facility. The screened fraction is mixed with lime in the mixer (DM 215 E) and reinstalled in the landfill too.

This procedure mainly applies to municipal waste landfills. The processing of slag and mine dumps will not be considered here.

The contribution margin for the process is mainly made through the upgrading and provision of future building areas. If the landfill remains, its volume is reduced by removing the useful fractions. So the landfill capacity increases. Useful fractions, which are extracted: 

  • REFUSE-DERIVED FUELS (coarse fraction)
  • REFUSE-DERIVED FUELS (light fraction, s. top left corner of the picture)
  • SECONDARY RAW MATERIALS (ferrous metals, s. top right corner of the picture)


The fine fraction and the heavy materials are reinstalled or processed further.
