Kukje Environmental Technology is dedicated to developing technologies that turn livestock manure and organic waste into valuable resources. After introducing Korea’s first solid-liquid separator, we commercialized an eco-friendly liquid-fertilizer production system capable of advanced purification, sterilization, and deodorization—becoming the first in Korea to obtain Green Technology certification for our self-heating, aerobic Bacillus liquid-fertilizer process (A2B). Today, we are advancing our self-heating–anaerobic–aerobic biogas process (A3) to realize a closed-loop environmental solution that converts waste resources into energy and fertilizer. Moving forward, we will continue to lead a sustainable future in agriculture and energy through cutting-edge microbial applications, biomass utilization, and innovative new processes.
