Brazil's Vale has successfully tested biochar on a large scale. The purpose of the biochar is to replace the mineral coal used to produce iron ore pellets to reduce emissions.

Vale planned to replace all the coal used in 12 pellet plants with biochar, including 11 pellet plants in Brazil and 1 pellet plant in Oman, to reduce emissions by 16%.

Vale's pellet plant near São Luís produced 57,000 tons of pellets, of which biochar accounted for 25% of the total coal use.

In addition, Vale planned to use 50% of biochar for another test, and a 100% test was expected in 2022.
