D-NOSES aims to kickstart a much needed collaborative journey to tackle the problem of odours at a global scale by developing coordinated local case studies in 10 European and non-European countries for validating methodologies and producing DIY guidelines for project replicability. The  pilot studies will apply and evaluate the proposed methodologies and tools for stakeholder engagement and the co-creation of possible solutions.

The pilots will be chosen and fully defined in due course as the project progresses. Here we present some of the early proposed pilot cases.

Forum Area, Barcelona

There is an odor nuisance problem in the Forum Area, where the Universal Forum of Cultures was held in 2004.The area is used for many international congresses, the music Festival Primavera Sound and many other events.

It is surrounded by

  • a bio-methanisation waste treatment plant (260,000 tn of MSW/yr.),
  • a waste incineration plant,
  • a covered Waste Water Treatment Plant (WWTP) underneath the Forum, with a treatment capacity of 3 M inhabitants eq, the biggest in Catalonia, and;
  • a wastewater sludge treatment plant.

The odours are always present and, depending on the time of the day and the meteorological conditions, one can smell fresh wastewater, sludge, fresh waste, decomposed residue or biogas.

Work is expected to be done in collaboration with neighbourhood associations (e.g. Associació Zona Fòrum, Front Marítim, Movimiento Diagonal Mar i Maresme), the Barcelona City Council, AMB (Barcelona Metropolitan Area managers of the Ecoparc and the WWTP) and the large company Aigües de Barcelona.

City of Taranto, Italy

Taranto is a city in Southern Italy which is infamous for its extensive industrial area being very close to the residential areas and the historical old town.

The city has been seriously afflicted by a strong environmental pollution produced by the different plants in the industrial area, which is a large center for steel production (it is located the biggest metallurgic center in Europe) and petroleum refining. Moreover, there are also other facilities among them a landfill, a cement plant and a military arsenal. All of these industrial sources produce odour emissions and annoyance for the residents living in the area. Most complaints arrive from the area “Tamburi”, which is the closest to the industrial area, or from the neighbouring town of Statte.

Complaints are often concentrated during night-time, which makes direct sampling on site problematic. Previous studies have confirmed the problem and high levels of H2S. Since no limit values for H2S, either for an industrial or an urban context, have been established in Italian legislation on pollution, it has so far been impossible to find legal ways of dealing with this problem.

São João da Madeira, Portugal

From the 1970s, an animal by-product processing plant has been causing odour nuisances in the municipality, located 1,3 km away from the city centre. The whole surrounding area has been affected, in a radius that extends for several kilometers, depending on the orientation of the winds and atmospheric conditions and has consistently reached other municipalities including Santa Maria da Feira. These processing plants continue to generate controversy between the population and its administration. While everyone recognizes their economic value and the wealth they create in jobs, it is no less true that the odour emissions far exceed the radius of  the 1 kilometer limit that their managers claim they achieve.

Several actions have been put in place, but the situation still persists. A private mapping platform (Odourmap) was used from 2013 to 2015 with the collaboration of the citizens, who were disappointed after their crowd-sourced data had no relevant effect. In 2016, a social movement of protest achieved to gather 5000 signatures and submitted a request to the Assembly of the Republic of Portugal, which decided to issue the resolution 190/2017 recommending the government to take the necessary measures to solve the environmental problems.
