Scientists are working on Green Steel as the climate change world turns on coal

SSAB expects to produce 1.3 million tonnes of green steel annually by 2026.

In Australia, Professor Sahajwalla leads a team that has developed another form of green steel.

In the process, coal already used around the world is replaced by used car tires in the furnace, releasing both carbon and hydrogen with heat.

However, Professor Sahaziwara, a world leader in the field of industrial recycling, is still unsatisfied. Her team is working with MolyCop, a global mining and metal company, at its Newcastle plant to further refine the process.

They are developing steel recycling methods that replace coal with not only tires, but also plastics, electronic waste from which metal components have been removed, and various wastes such as coffee grounds.

BHP’s forecasts released this year allowed the new process to replace coking coal, but by 2050 it was expected that traditional furnaces would still produce most of the steel.

However, mining tycoon Andrew “Twiggy” Forest, who is investing in hydrogen technology, said he believed that the transition from coal would occur “almost violently.”

“I don’t think coal-fired blast furnaces will be operational by 2050. Period.”

“I don’t think coal-fired blast furnaces will be operational by 2050. Period,” he said in March.

Professor Sahajwalla considers what is now called waste as a valuable resource and reuses it indefinitely in order to properly deal with not only global warming but also wider damage to the environment. I think we need to learn to reuse, not use. It was abandoned.

According to Professor Sahajwalla, the decarbonized economy is almost completely electrified, and most of the key elements needed for the process, such as zinc, manganese and cobalt, are routinely discarded.

“I’m a little crazy to see the old remote controlled being thrown away with the batteries,” she says.
