Slow but thorough method: First you assess your footprint and then embark on an astute reduction strategy cutting your emissions every year until you have achieved carbon neutrality.

By analyzing and researching utilization of BF dust, a technology of dealing with the BF gas slime adopting the containing carbon pellet direct roasting reduction method was put forward.

Some factors affect solid carbon reduction(DR) were analysed in this thesis with the experimental method of orthogonal design. The optimum program was reached for directing actual production.
