Two murals made of photocatalytic, smog-eating paint have gone up in Bangkok, Thailand, and Warsaw, Poland, as part of a project dubbed Converse City Forests.
Converse, the American shoe company, is collaborating with artists in 13 cities around the world to create these giant murals, using a special kind of paint that helps clean the air.
"This technology uses light energy to break down noxious air pollutants and convert them into harmless substances," Converse said. "Any surface coated with this paint becomes an active air-purifying surface that helps protect people from harmful gases."
The mural in Bangkok was created in partnership with two artists: Teerayut Puechpen, known as TRK, and Sorravis Prakong. At the center of the mural, viewers see two hands. It's meant as a symbol of unity, and in addition to beautifying the city, the mural has the environmental impact of planting 150 trees, Converse said.
