In Drew Simms’s Short Film, Yellowstone National Park’s Gentle Giants Hunker Down in Subzero Temperatures

Rugged survivors of the Northern Great Plains, bison were nearly eliminated in the late 19th century due to overhunting. The creatures’ highly profitable, heavy wool hides were fashionable for jackets, and the U.S. government also sanctioned their slaughter as a way to compel Native Americans, who relied on the animals for sustenance, onto reservations. Still listed as a “near threatened” species and considered “ecologically extinct,” bison no longer play a role in prairie biodiversity. But their survival today is due in large part to dedicated, often Indigenous-led regeneration efforts across the plains.

Since prehistoric times, the only place where bison have lived continuously is in what is now Yellowstone National Park. The massive animals, which can weigh up to 2,000 pounds, develop a burly undercoat of coarse fur that protects them from the elements, keeping them warm and comfortable in temperatures as low as -40 degrees Fahrenheit. On a week-long camping trip last winter, photographer Drew Simms captured families of bison, along with other critters who frequent the area, in the stunning short film “-37°F in Yellowstone National Park.”

Featuring some of the thousands-strong herd that wanders freely through the expansive park and nearby areas of Montana, Simms observed steaming geysers, sly coyotes, and ice-coated mineral deposits in otherworldly scenes captured during the season when up to 200 inches of snow coats the landscape.

ABB receives EPD status for gearless mill drive ring motor

ABB has gained Environmental Product Declaration (EPD) status for its Gearless Mill Drive (GMD) ring motor — technology used to drive large grinding mills in the mining industry.

An EPD is a standardised document that provides detailed information about the environmental impact of a product throughout its life cycle. Based on a comprehensive Life Cycle Assessment (LCA) study, the EPD highlights ABB’s commitment to transparency, environmental responsibility and supporting customers in making informed decisions on sustainability in their supply chains.

ABB analysed the environmental impact of a ring motor across its entire life cycle from supply chain and production to usage and end-of-life disposal. The study was conducted for a ring motor of a semi-autogenous grinding (SAG) mill with an installed power of 24 MW and was based on a reference service life of 25 years.

“Sustainability is at the core of our purpose at ABB, influencing how we operate and innovate for customers,” said Andrea Quinta, Sustainability Specialist at ABB. “By earning the Environmental Product Declaration for our ring motor, we emphasise our environmental stewardship and industry leadership for this technology. We adhered to the highest standards throughout this process, as we do in the ABB Ring Motor factory every day. This recognition highlights to the mining industry what they are bringing into their own operations when they work with ABB.”

The comprehensive LCA was conducted at ABB’s factory in Bilbao, Spain, and was externally verified and published in accordance with international standards ISO 14025 and ISO 14040/14044. It will remain valid for five years.

The ring motor, a key component of the GMD, is a drive system without any gears where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. It optimises grinding applications in the minerals and mining industries by enabling variable-speed operation, leading to energy and cost savings.

The full EPD for the ABB GMD Ring Motor can be viewed on EPD International.
