New Delhi [India], May 20 (ANI): Geocycle, the global waste management arm of construction solutions provider LafargeHolcim, implements innovative bubble curtain technology in India for the first time to prevent plastic from entering the Yamuna River .
The bubble barrier was established on the Mantola Canal in the city of Agra which carries 40% of its storm and wastewater.
A bubble curtain is a non-invasive solution to prevent plastic from entering the oceans. Vessels and fish can pass through air bubbles, but plastics will be stopped.
The bubble screen is created by a specially designed air tube that is placed diagonally across the bed of a canal or river. It brings the waste to the surface and channels the plastic to the banks where it can be extracted.
The bubble barrier is generated using compressed air passing through tubes placed at the bottom of the channel. These tubes are connected to a compressor powered by renewable solar energy.
In addition, aeration in the canal will increase the dissolved oxygen levels in the wastewater / storm water resulting in an overall improvement in water quality.
“Geocycle’s approach to cleaning plastic from rivers is distinct from other river cleaning projects that rely on landfill or incineration,” said Neeraj Akhoury, CEO India of LafargeHolcim and MDCEO of Ambuja Cements Ltd.
“Geocycle’s co-treatment infrastructure guarantees a safe and environmentally friendly final treatment of the collected waste: the co-treatment in a cement kiln recovers energy and recycles the value of the materials in the waste, leaving no residue, ”he said in a statement.
“These two technologies – bubble curtain and co-processing combined – provide a good opportunity to tackle the challenge of marine litter by tackling the problem at the source,” Akhoury said.
LafargeHolcim is the parent company of Ambuja Cements and ACC Ltd, the two main cement companies in India.
Geocycle, under the auspices of the Air Pollution Action Plan of the United Nations Environment Program (UNEP) India, has partnered with Agra Municipal Corporation and GIZ India with Canadian Pond in as a technology provider, working on the mission of making Agra plastic free.
Once successful, this technology will be replicated in other countries.
Plastic waste extracted from the canal will be sent to a municipal solid waste treatment and material recovery facility. Recyclable plastics will be sent to recycling facilities while non-recyclable plastics will be sent to Geocycle facilities for pre-treatment followed by co-treatment in ACC or Ambuja cement kilns.
Almost 11 million tonnes of plastic enter the oceans each year, making it one of the biggest threats facing society. If this trend continues unabated, there will be more plastic than fish in the oceans by 2050.
Most of the plastic in the ocean gets there through rivers. (ANI)
