The algae 'biocurtain' cleaning city air

Imagine if air pollutants could be transformed into something useful.

That's exactly what this ''biocurtain'' does - by harnessing the power of algae.

(SOUNDBITE) (English) CO-FOUNDER AND DIRECTOR OF ECOLOGICSTUDIO, DR. MARCO POLETTO, SAYING: "We inoculate air like, let's say dirty urban air from the bottom.

Air naturally rises through the system and comes into contact with the algae cells.

The algae cells as I said are extremely voracious organisms so they eat up all the particles and release oxygen as a consequence of photosynthesis." Not only is oxygen released, but the absorbed carbon dioxide helps the algae to grow and create biomass, which can then be used as the raw material for bioplastic, biofuels, fertilizers, food, and cosmetics.

The founders of EcoLogicStudio hope to see their creation hung from commercial buildings like warehouses or residential buildings in future.

It already happened in Dublin last year.

Several biocurtains were hung on a conference center during the EU-supported Climate Innovation Summit.

And in September, biocurtains will cover the outside of a multi-story car park in Austria - where they'll stay for at least a year.

A report published by the Global Carbon Project at the end of last year predicted a 3% increase in world emissions, due to the sustained use of coal, oil, and natural gas.

(SOUNDBITE) (English) CO-FOUNDER AND DIRECTOR OF ECOLOGICSTUDIO, DR. MARCO POLETTO, SAYING: "Our technology is both beautiful and highly performative and I think we can, that's where the big impact will happen.

It will literally be like the equivalent of a micro-forest being planted.

But with virtually no surface area being taken." The founders estimate that just two square meters of curtain have the same ability to capture CO2 as a large tree.
