The Plastic Recycling Process. The chart on the right shows the seven different plastic recycling symbols marked on the bottoms of plastic containers. The recycling mill sorts the used plastics by these symbols and may perform an additional sort based on the color of the plastic. Once sorted, the plastics are chopped up into small pieces and chunks.
Recycling this product has become possible due to changes in iron production methods as it can be mixed with other iron sources in smelters as well as with lower grade ores prior to shipping. Mill Scale is traded effectively in the same manner as primary mined iron ore fines.
