The CEJI project is a technical project that mixes all combustible waste and regenerates energy. It aims to build an ecosystem and create a CEJI platform through the combination of technology and blockchain. Facilities (CEPs) using CEJI's core technology are environmentally friendly facilities that do not emit greenhouse gases, and realize energy regeneration such as oil, natural gas, hydrogen, and electricity by mixing and processing all combustible waste. The core technology of the CEJI project is a technology that simultaneously solves environmental and energy issues by generating waste disposal and energy in an environmentally friendly and safe manner that does not emit greenhouse gases.
