Technical tours

As a complement for the ISWA 2019 World Congress a set of four technical visits to local waste treatment facilities has been scheduled.

Three of the visits cover most of the waste tratment plants that compose the Biscay waste treatment infrastructure. These plants have been built in the last 2 decades, under the succesive Waste Management Plans, under a Public Private Partnership scheme. Garbiker, the local (Biscay) public waste management company is a shareholder in these plants.

According to the EU Waste Management Hierarchy the existing infrastructure in Biscay can be classified as:

  • Recycling facilities: BTB (construction and demolition), BZB (packaging), BPB (plastics), Berziklatu (bulky), Ekorrepara…
  • MBT facilities: TMB (Artigas)
  • Composting: Konpostegia (Artigas)
  • WTE facilities: Zabalgarbi (Artigas)
  • Disposal facilities: Artigas landfill, others in stand by

The fourth visit covers the recently built Zubieta Environmental Complex in San Sebastián (Gipuzkoa). These facilities, some of which are still in their construction steps, are owned by GHK, the local (Gipuzkoa) public waste management company.
