Technical meeting with UPM and Madrid City Council

Technical meeting with UPM and Madrid City Council

Today, we have met with UPM (Universidad Politécnica de Madrid) and Madrid City Council at IETcc (Eduardo Torroja Institute for Construction Science). Topics such as next actions to perform, tests, expositions and meetings have been covered.  

Cleaning the platforms

Cleaning the platforms

From the first time, one of the tasks in LIFE Photoscaling project was simulating real life conditions over our products. That aim includes the effects of environmental conditions, vehicles abrasion and also the cleaning by City Council workers. Today, this last condition has been simulated. The process of cleaning is divided in two ones: 1. Cleaning the “Leaching Bank of Proofs”. This action has been […]

Leachate collection

Leachate collection

One of the photocatalytic characteristics checked is if they loose some kind of contaminant. This thing would become the photocatalytic material dangerous and pointless compared with the environmental damage. In order to control this hypothetical situation, one pit for each surface were built and the leachates inside them have been collected every time it has rained.

Chewing gum and grease removals

Chewing gum and grease removals

The common dirt in our sidewalks, pavements and roads are chewing gums from (filthy) people and grease from vehicles. In this project, besides the mentioned graffiti, gums and grease have been spread over the platforms to prove if the photocatalytic materials are able to remove them. In the photo below, they can be seen: the gum (small white circle on the left) and the grase (next […]

Removal of NOx test

Removal of NOx test

The removal of NOx test is the most typical test to know how powerful the photocatalytic material is. In LIFE Photoscaling project, it is pretended to scale from laboratory tests to real life surfaces. To do that, it was necessary to make a “in situ” meter available. So, this new meter was built, patented and used to perform every “in situ” test.

Air pollutants variations recorded

Air pollutants variations recorded

In addition to the measuring of NOx degradation, in LIFE Photoscaling project, these contaminants and other ones are constantly measured by using two types of meters: The first one (in the left of the picture) reveals the live concentration of NO, NO2, O3 and, moreover, relative humidity and temperature (both also registered by weather stations). The second one (in the right of the picture) keeps a […]

Weather stations

Weather stations

Photocatalytic process depends on weather conditions, specially sun radiation and atmospheric humidity. In order to  collect these data and be able to compare with the results of the degradation of pollution, two weather stations have been placed at the photocatalytic slabs. The first weather station is located in IETcc – CSIC (Madrid).   The second one has been placed in IETcc – CSIC (Arganda del […]

Cleaning graffiti

Cleaning graffiti

A huge amount of test will be proven in all of these photocatalytic materials. One of them is the self-cleaning test, but, this time, materials will clean (or not) graffiti painting instead of rhodamine, commonly used. Some initial photographs:  

Platforms construction successfully finished

Platforms construction successfully finished

The two photocatalytic platforms on a pilot plant technical scale have been constructed. Each photocatalytic platform consists of several banks of proofs containing sets of slabs of photocatalytically active materials. Following, few images of these platforms can be seen. Part of finished the Platform 1 (Madrid)   Part of the finished Platform 2 (Arganda del Rey)

Material 7/7: COVERLITE from Bacchi

Material 7/7: COVERLITE from Bacchi

Today, the material spread has been Coverlite from Impresa Bacchi. This is the third and last material of the emulsion coatings group. The surfaces used to spread on the material have been asphalt as well as Madrid paving tiles.
