Micro-pelletizing and briquetting processes have helped customers recover value from previously dismissed waste and generate new materials that have bolstered steelmaking capacities.
Background
Steel plants generate numerous finely-sized waste streams that contain value, yet cannot be recycled back into the steel making process in their current form. This pointed to the need to develop specialized handling and agglomeration process techniques to generate larger, uniform product sizes and chemistries so the carbon, iron and mineral values contained could be recovered. Several hundred thousand tonnes per year of previously wasted material could thereby be reused once in an acceptable form.
