Brazilian miner Vale produced iron ore pellets on an industrial scale for the first time without adding coal, company executives told Reuters on Wednesday, in a major step toward reducing the company's carbon footprint.

In pellet production, coal is usually mixed with iron ore before being heated in plant furnaces. In Vale's pilot project, conducted in February in Minas Gerais state, the so-called biocarbon obtained from biomass replaced traditional coal, an especially dirty fossil fuel. Industrial heavyweights like Vale face growing pressure to lower harmful emissions that contribute to global warming, from governments, activists as well as investors.
During Vale's pilot, 15,000 tonnes of coal-free pellets were made with 100% biocarbon from certified supplies, according to the company. Biocarbon is a renewable energy source obtained through biomass carbonization, which results in much lower emissions.
