The article explores a complex system called integrated co-production in coal chemical engineering. By combining different coal conversion technologies, coal can be used more efficiently, leading to increased financial benefits. The system also aims to be environmentally friendly in coal utilization. The researchers suggest creating a specialized agency to coordinate manpower, technology, and finances to optimize this integrated approach. In simple terms, they're looking at ways to make better use of coal resources while being mindful of the environment and maximizing economic gains.
