AI Technical Summary
Technical Problem
Conventional Carbon Capture and Storage (CCS) technologies face challenges such as high energy consumption, transportation difficulties, and leakage of captured carbon, while ammonia and urea plants emit CO2 and wastewater that are not effectively utilized, leading to environmental impact.
Method used
Culturing algae using flue gas and wastewater from urea and ammonia plants to convert CO2 and nutrients into biomass, which can be used as a fertilizer or bio-fertilizer, thereby sequestering carbon and reducing environmental impact.
Benefits of technology
The method effectively sequesters CO2 and produces bio-fertilizer, addressing environmental concerns and meeting the demand for fertilizers by utilizing plant emissions.
