1 MECCATECH

2 TASK 1 – Identify the problem Problem: Turin’s urban pollution In particular Porta Nuova Area: Slowed traffic in many surrounding streets Approximately cars per hour between 7:40 and 8:40 Photo taken on 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 Averange daily data

4 Photo taken on How does it work? 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 Task 2 – Solution: Photocatalysis What is it? A photochemical process similar to photosynthesis An accelerator of natural oxidation processes

5 How to apply? Possible applications Asphalt Paints Plants

6 Asphalts Photo taken on – Modified Main features 32 tons of pollutants are absorbed annually by 1 square kilometer the most important: nitrogen dioxide; carbon monoxide; particulate matter; Formaldehyde; Sulphur dioxide; 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

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 units Public health expenditure reduced

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. Photo taken on

9 Plants It is possible to use plants as an alternative to paints In less polluted places Absorption capacity is less than asphalt and paints Cheaper than asphalts and paints Photo taken on The most effective are: Edera Dracena
