Which territorial clusters are taken into consideration?

The integrated treatment and valorization of different bio-waste is functional to implement a novel "urban bio-waste biorefinery" which, in the context of the ResUrbis project, will be accomplished with the creation of autonomous clusters. These latter represent "waste basins" where the recovery strategies are affordable and recovery cycles are possibly closed within the cluster itself, e.g. without the need to transport either bio-waste or the resulting bio-based products for long distances. The selected territorial clusters are distributed in different European countries with different geographical, economical, and social characteristics and are, specifically, located in:

  • Province of Trento (Italy)
  • Barcelona Metropolitan area (Spain)
  • Lisbon Metropolitan area (Portugal)
  • South Wales (United Kingdom)

Therefore, the selected clusters include both big and small cities and their sizes ranges from 500.000 (Trento, Italy) to 3.000.000 (Barcelona Metropolitan, Spain) inhabitants. More in detail:

  • The area of the Province of Trento represents the "Trentino cluster" which, with a population of 534,405 inhabitants living in 217 municipalities, is the smallest cluster in the RES URBIS project. As for municipal solid waste, the total amount produced and managed, as an example, in 2014 was 263,900 tons. Separate collection of municipal solid waste reached 75% in 2014 and the residual (grey) waste was only 64,000 tons per year, roughly corresponding to 100 kg per person per year. The organic waste was 53,500 tons per year.
  • The Barcelona Metropolitan area, which represents the "Barcelona cluster", counts a total population of 3.214.211 inhabitants in 36 municipalities and it is around 6 times bigger than the "Trentino cluster". The total amount of waste produced and managed in the metropolitan area of Barcelona in 2014 has been 1,377,952 tons including 185,335.21 tons of Bio Waste. The total amount of sludge produced in 2014 was 54,754 tons of dry matter.
  • The Lisbon Metropolitan area, referred to as the "Lisbon cluster", is centered in the Portuguese capital city of Lisbon. It is the largest population concentration in Portugal counting a total population of 2,821,876 inhabitants in 18 municipalities. This cluster produces around 1,50,000 tons of waste per year, 80% of which is not recycled. As for sludge, about 125,000 tons of dried sludge are produced per year in the Lisbon Metropolitan area.

The "South Wales cluster" comprises the area between Swansea in the west and the border with England in the east. It is the most densely populated area in the South West of the United Kingdom with a population of approximately 2.2 million which represents approximately 70% of the total population of Wales.
