Geocycle—the global waste management arm of LafargeHolcim, that manufactures building materials, will implement the innovative ‘bubble curtain’ technology for the first time in India to stop plastic from entering the Yamuna River. A bubble curtain is a non-invasive solution to stop plastic from entering the oceans. Ships and fish can pass through the air bubbles, but plastics will be stopped. The bubble screen is created by a specially designed air tube which is placed diagonally on the bed of the canal or river. It brings waste to the surface, channels the plastic onto the banks where it can be extracted.
