Punjab unveils Pakistan’s first EPA-certified ‘Liquid Tree’ to combat pollution

• CM Maryam Nawaz calls project a milestone in environmental transformation

• Says more than 100 microalgae species studied from Karachi to Khyber during 7-month research which identifies most effective strain in Sukkur

• AI-powered system tracks real-time carbon absorption and oxygen release

• EPA expands green agenda with plastic bans and industrial buffer zones policy

 LAHORE: Punjab Chief Minister Maryam Nawaz on Sunday reaffirmed her government’s commitment to transforming Punjab into an environmentally sustainable and climate-resilient province, announcing a landmark initiative with the introduction of Pakistan’s first Environment Protection Agency (EPA)-certified “Liquid Tree”.

According to the chief minister, this marks the first technology certified by the Punjab EPA since 1987. The innovative “Liquid Tree” is an artificial, bio-engineered system designed to absorb carbon dioxide from the atmosphere and contribute to environmental improvement.

The chief minister said more than 100 species of microalgae were collected from across the country, ranging from Karachi to Khyber. Over a period of seven months, researchers evaluated the carbon sequestration capacity and efficiency of each species. The most effective strain was identified in Sukkur, Sindh, and later cultivated in collaboration with Government College University (GCU) Faisalabad.

The system incorporates an AI-based calculator that provides real-time monitoring of carbon dioxide absorption and oxygen release, enabling precise environmental impact assessment.

Maryam Nawaz praised the Environment Protection Agency (EPA), researchers, and technical teams involved in developing the bio-artificial tree, saying the successful trial reflects the innovation, expertise, and dedication of Punjab’s scientists, bioscientists, and environmental experts.

Following successful testing of the technology, she approved its expansion across the province, describing it as a major milestone in Punjab’s environmental reform agenda.

“The successful trial of the Liquid Tree will bring a significant change in the fight for environmental improvement in Punjab,” she said.

In the first phase, Liquid Trees will be installed at major shopping malls in both indoor and outdoor environments. The chief minister expressed confidence that the technology would prove to be a game changer in reducing urban pollution levels.

The Liquid Tree operates through algae cultivated in water within a bioreactor system, which absorbs carbon dioxide from the surrounding environment. The chief minister described it as one of the most advanced scientific approaches to addressing carbon emissions and urban smog.

She added that such artificial trees, when installed in large commercial buildings, plazas, and business districts, would improve environmental quality in a manner comparable to natural trees.

Separately, in April, the EPA intensified efforts to establish plastic-free zones in major urban markets, announcing a complete ban on plastic bags below 75 microns.

The authority has also introduced a broader regulatory framework focusing on green buffer zones around industrial areas, mandatory plantation drives, and stricter controls on tree cutting to curb industrial pollution.
