  2. TASK 1 – Identify the problem Problem: Turin’s urbanpollution In particular • Porta Nuova Area: • Slowedtraffic in manysurroundingstreets • Approximately 1500-2500 cars per hour • between 7:40 and 8:40 Phototakenon Geoportale di Torino

  3. Target Groups Residents and workers Car Bus On foot Emissions: 1.4 Kg 0.85 Kg 0 Kg Distance: 8.1 Km 9.8 Km 1.8 Km Averangedaily data

  4. Task 2 – Solution: Photocatalysis Whatisit? Howdoesit work? • A photochemicalprocesssimilartophotosynthesis • An accelerator of natural oxidation processes • The light, natural or artificial, activate the photocatalyst (TiO2) • Titanium dioxide form the reactant molecules to oxygen • These reagents (ROS) in contact with the pollutants transforming them into CO2 and H2O neutralize Phototakenonwww.aironhealth.com

  5. Howtoapply? Possibleapplications AsphaltPaintsPlants

  6. Asphalts Mainfeatures • 32 tons of pollutants are absorbed annually by 1 square kilometer • the mostimportant: • nitrogendioxide; • carbonmonoxide; • particulatematter; • Formaldehyde; • Sulphurdioxide; • benzene • Average price is 25 € per square meter The CNR is estimated that 1 m2 can get to remove about l '80% of the pollutants present in 80 m3 of air in just 1 hour Phototakenonwww.senini.it – Modified

  7. Asphalts Why use them? The main advantages • They have an average life of 12 years compared with 7 of traditional asphalts • Their cost is absorbed over time due to less maintenance • The catalyst is not consumed and remains effective throughout the life of asphalt • Annual deaths reduced by 180-300 units • Public healthexpenditurereduced

  8. Paints Why apply on our homes? • Because their effects are equal to those of asphalts • Why stay clean building exteriors • Because their cost is slightly higher than that of conventional paints. Phototakenonwww.csbari.it

  9. Plants It is possible to use plants as an alternative to paints In lesspollutedplaces • Absorption capacity is less than asphalt and paints • Cheaperthanasphalts and paints • The mosteffective are: • Edera • Dracena Phototakenonwww.fototoscana.it
