Nualgi Nano Biotech to save polluted Ulsoor Lake in Bengaluru

Bengaluru: A novel product developed by Nualgi Nano Biotech (NNB), a low-profile biotech company here, is helping clean up sewage-polluted Ulsoor Lake where thousands of fish were found dead last week owing to depletion of dissolved oxygen.

Ulsoor Lake, famous for army rowing competitions as well as for boating among tourists, was seen covered with thousands of dead fish that left people here stunned.

“Called Nualgi, it is a mixture of micro-nutrients in the form of nano-particles, including silica, iron, and manganese,” said Thothathri Sampathkumar, who founded the company which patented the product in India in 2008.

“‘Nualgi’ triggers the rapid growth of a type of algae called ‘diatoms’ and the oxygen released by the diatoms through photosynthesis quickly increases the dissolved oxygen level of water and thus keeps the pond clean,” Sampathkumar told IANS.

According to Sampathkumar, one kg of Nualgi can treat four million liters of water, adding that the affected fishermen — who have the contract for fishing in Ulsoor lake – have purchased 40 liters of “Nualgi” from his company on March 6 to increase the dissolved oxygen level and stop further fish death.

“We can see the results very soon,” added Sampathkumar.

“Nualgi can be used to grow “diatom” algae in any water including sewage polluted water. The growing “diatoms” absorb carbon dioxide from the air and, by photosynthesis, release oxygen at the micro plant level. The oxygen released helps aerobic bacteria breakdown organics in the water into base constituents, thereby eliminating the stinking odour from the water.

The growing “diatoms” are eaten by zooplankton that, in turn, is consumed by fish. “The fish clean up the lakes of all ‘diatoms’, zooplankton and organics, thus restoring the polluted lakes and water bodies to its original glory,” said Sampathkumar.

According to him, the mass fish death in Ulsoor lake took place, perhaps because the fishermen ran out of their stock of Nualgi or missed its timely application.

The tragedy could have been averted had the authorities installed monitors to continuously record the level of dissolved oxygen (DO) in the lake water and alert them when DO falls below a critical level. These DO monitors, he said, are now commercially available.

“Nualgi has been patented also in the US, Britain, Germany, and South Africa. Five years ago, the three-acre “Duck Pond” in New York state in the US that “was in a highly impaired state with a variety of water quality issues” was restored to normal health thanks to “Nualgi.”

Lake Savers, the US company that tried it out, had acknowledged in an email to Sampathkumar that the water quality of “Duck Pond” showed a “remarkable and sustained improvement” after a single dose of Nualgi application and that “fish productivity and health improved dramatically.”

Encouraged by its successful experiment in New York’s “Duck Pond”, Lake Savers had obtained clearance from the US Environmental Protection Agency for using Nualgi on a large scale in the country.

Nualgi, that requires no skilled labor, is an economical alternative to treat sewage and organic wastes in “eutrophic” lakes and ponds contaminated by nitrogen or phosphorus compounds, such as by laundry detergents, untreated sewage, and fertilizer run-off from agricultural lands.

“Nualgi is being used in many lakes in southern India for the past several years and fishermen are buying the product to increase fish catch in water bodies.

Sampathkumar is hopeful of promoting its use worldwide to revive fresh water “eutrophic lakes” and “dead zones” in coastal regions that are so much deprived of oxygen that they can’t support aquatic life. (K.S. Jayaraman, IANS)

‘Humans Have Caused Pollution and Humans Can Fix It too’, Says UN Environment Head; Asserts Asia Must Lead Efforts for a Pollution-Free Earth

World Health Organization figures show Asia has 25 of the world's 30 most-polluted cities in terms of fine particles in the air that pose the greatest risks to human health

Bangkok, September 9, 2017 : Asia-Pacific — home to more than half the world’s population and some of its fastest-growing economies — is a key battleground in the fight against pollution, one of the biggest threats to the planet and its people, the U.N. environment chief said.

An estimated 12 million people die prematurely each year because of unhealthy environments, 7 million of them due to air pollution alone, making pollution “the biggest killer of humanity,” Erik Solheim told the first Asia-Pacific Ministerial Summit on the Environment in Bangkok this week.

Humans have caused pollution and humans can fix it, said Solheim, executive director of UN Environment, in an interview with Reuters at the four-day summit.

“The struggle for a pollution-free planet will be won or lost in Asia — nowhere else,” said the former Norwegian minister for environment and international development.

The sheer size of Asia-Pacific, as well as its continued economic growth, put it at the heart of the challenge, he added.

The region’s development has been accompanied by worsening pollution of its air, water and soil. Its emissions of planet-warming carbon dioxide doubled between 1990 and 2012, and the use of resources such as minerals, metals and biomass has tripled, according to the United Nations.

World Health Organization figures also show Asia has 25 of the world’s 30 most-polluted cities in terms of fine particles in the air that pose the greatest risks to human health. The pollution comes largely from the combustion of fossil fuels, mostly for transport and electricity generation.

Solheim said Asia is also a major contributor of plastic polluting the world’s oceans — and solutions can be found in the region. He pointed to a huge beach cleanup campaign in Mumbai that inspired Indian Prime Minister Narendra Modi to overhaul the country’s waste management system.

“There’s enormous environmental opportunity,” Solheim said. “Asia has by and large strong governments, and they have the ability to fix problems.”

Coal no longer king?

Solheim said fighting pollution by moving toward renewable energy sources such as wind and solar would also benefit efforts to curb climate change, which scientists say is stoking more deadly heatwaves, floods and sea-level rise around the world.

But environmentalists worry that Asia’s demand for coal, the most polluting of the major fossil fuels, is likely to grow for years to come.

Figures from a forum organized by the King Abdullah Petroleum Studies and Research Center in Singapore earlier this year show that some 273 gigawatts of coal power are still being built, although much more has been put on hold.

In July, analysts told Reuters that Japan, China and South Korea are bank-rolling coal-fired power plants in Indonesia despite their pledges to reduce planet-warming emissions under the Paris climate deal.

The landmark 2015 Paris Agreement seeks to limit the rise in average world temperatures to well below 2 degrees Celsius above pre-industrial times. Experts say curbing or ending the use of coal is required if this goal is to be reached.

Globally, many countries — including China — are shutting down or suspending plans for coal-fired power plants as costs for wind and solar power plummet.

Solheim is optimistic, noting that the International Energy Agency significantly raised its five-year growth forecast for renewables led by China, India, the United States and Mexico.

“There are very, very few people in the world who believe that the future is coal,” he said. “I think we will see the shift [to renewables] happening much faster than people tend to believe.”

On U.S. President Donald Trump’s decision to pull his nation out of the Paris Agreement, Solheim sees a silver lining.

“The surprising judgment of history may be that Donald Trump did a lot of service to this fight against climate change by withdrawing, because he galvanized the reaction of everyone else,” said Solheim.

“All the big, iconic companies of modern capitalism — Apple, Google, Microsoft, Amazon — they immediately said, ‘We will move into the green economy.'” (VOA)
