SOROWAKO, Indonesia — Red hot sparks fly through the air as a worker in a heat-resistant suit pokes a long metal rod into a nickel smelter, coaxing the molten metal from a crucible at a processing facility on the Indonesian island of Sulawesi.
Located beside a crystal-blue lake in the lush jungle of Sorowako, South Sulawesi, Vale Indonesia — a subsidiary of Vale international — runs its smelters entirely from hydroelectricity. Vale says that can reduce its emissions by over 1.115 million tons of carbon dioxide equivalent a year, compared to using diesel. Vale claims it has reduced its greenhouse gas emissions nearly a fifth since 2017.
Companies are learning from past mistakes of the industrial revolution, where reliance on fossil fuels was paramount for development, said Michael Goodsite, a pro vice chancellor and professor of civil and environmental engineering at the University of Adelaide in Australia. Widodo visited Vale Indonesia’s Sorowako facilities in March, the same month a deal was signed for a $4.5 billion nickel procession plant to be built by Vale Indonesia with investment by Ford Motor Co.
The use as LNG as a “bridge fuel” has been contested by climate experts, as the fuel releases climate-warming methane and carbon dioxide when it’s produced, transported and burned. Having mining operations powered by renewable sources instead of fossil fuels could also help unlock green financing and attract future investors, said Aimee Boulanger, executive director of the Initiative for Responsible Mining Assurance.

Increasing steps by 3,000 per day can lower blood pressure in older adults, study findsAn estimated 80 percent of older adults in the U.S. have high blood pressure. Maintaining healthy blood pressure can protect against serious conditions like heart failure, heart attacks, and strokes. A new study found that adding a relatively minimal amount of movement, about 3,000 steps per day, can significantly reduce high blood pressure in older adults.
