Punjab expands Liquid Tree project to combat smog in Lahore and other cities

The Punjab government is expanding its 'Liquid Tree' project to address severe smog in Lahore and other urban areas. These installations use algae to absorb carbon dioxide and filter particulate matter, offering a nature based solution for air quality improvement. The expansion aims to place more units in high pollution zones across the province. While the concept is promising, the article lacks specific data on the number of new units, their expected carbon capture capacity, and the maintenance costs over time. Algae based systems require regular upkeep and water supply, which could be a challenge in some regions. Still, this is a practical step worth watching for anyone interested in urban decarbonization and pollution mitigation strategies.
