A2A Investor Relations Team

Bergamo technological park

A2A contributes to closing the solid urban waste cycle of rubbish coming from the city of Bergamo and a provincial catchment area made up of 22 municipalities that form the city’s first outer ring. Activities are carried out in the industrial site located towards the south eastern boundary of the Municipality of Bergamo in an area prevalently set aside for industry and crafts.
Inside this industrial area, there are currently operative plants for:

  • the treatment of residual urban waste collected during separate waste collection, which is then used to product alternative fuel for energy production (CDR)*;
  • storage of separated elements of urban waste prior to sending it to its final destination for recovery/waste disposal;
  • waste-to-energy processing of CDR by producing electricity from renewable or alternative energy sources, which is then introduced to the national grid and thermal energy distributed through the city district heating network.

*CDR: fuel from waste

Treatment of waste

Bergamo technological parkResidual urban waste from separate waste collection that cannot otherwise be recovered and reused is subject to a work cycle that involves:

  • a first grinding stage to make the material homogeneous and prepare it for the biological treatment phase;
  • a biological drying phase that is accelerated by passing air under the temporarily deposited static piles of waste;
  • separation takes places using a rotating sieve in order to eliminate any fine non combustible parts (inert materials, pieces of glass, etc.);
  • demetalisation takes place by separating both ferrous and non-ferrous waste, which is then sent for recovery;
  • a final grinding stage is carried out to prepare the material for the subsequent waste-to-energy process in a plant made for that purpose. 

Storage of waste

The previously separated waste, whether coming from domestic waste collection in the area or from special multi-material centres (ecology platforms) is stored in areas that are equipped and authorised for such purposes in order to:

  • provide a suitable support area to allow for the waste collection activities in the area to be optimised;
  • to optimise transportation to final destinations for recovery/waste disposal of separate waste reducing its potential environmental impact.
