The existing technology to environmentally clean up and exploit fossil mine head wastes as a greener alternative in the progression to a net zero operations cannot deliver a commercially attractive and environmentally positive solution.


A patented breakthrough technology, which allows environmental clean-up & industrial level commercial re-use of these discarded waste fines as a greener alternative fuel and metallurgical resource.



Five years of research and development to find greener solutions for the clean-up and re-use of carbonaceous, mineral and agricultural wastes.



Our patented process is controlled throughout by our custom designed software which maintains quality control and throughput resulting in a continuous flow of identical quality pellets.

The process takes in the washed fines at one end and processes onwards to the mixing stage where they are treated with our unique patented formula and then fed into the pelletizing unit.

The resultant formula & process treated pellets emerge for stacking and cold curing already having an inherent green strength sufficient to allow the cold curing process to commence.

Our Formula is unique in that it works at a molecular level and binds the washed fines into a smooth faced pellet.

What is unique about the Changeover Technologies patented Formula is that there are no deleterious additives added to the fines in creating their pellet form. The fines remain at the “pure” quality level they were originally washed to produce, as in low ash, high carbon fines. Hence our pellets are the equivalent of their desired end user products and can be used in a similar logistical and industrial manner.
