Walki upgrades green solutions for the Out-of-Home (OOH) advertising sector
Polyvinyl chloride (PVC) has for many decades been the preferred material for Out-of-Home (OOH) advertising billboards and banners despite posing substantial environmental risks. Its manufacturing process produces chlorine gas, while its disposal also releases dangerous toxins into the environment. The material is not biodegradable and hard to recycle and hence the only disposal options are either incineration or dumping it in landfills.
