MIT Startup Cuts Industrial Energy Use by 90% With $36M

A technology that dramatically cuts energy waste in factories is about to reach far more industries, thanks to a major funding boost that proves clean solutions can scale.

Via Separations, a startup founded by MIT researchers in 2017, announced $36 million in new funding to expand beyond pulp and paper mills into oil refining and chemical manufacturing. The Watertown, Massachusetts company has developed filtration membranes that replace energy-guzzling heating systems traditionally used to separate liquids in industrial processes.

The technology can reduce energy consumption by up to 90% in these separation processes, which are a massive source of industrial emissions worldwide. Instead of boiling liquids to separate them, Via Separations uses electricity-powered filtration systems that plug directly into existing equipment.

CEO Shreya Dave and CTO Brent Keller both worked on the original research as PhD students under MIT Professor Jeffrey Grossman, who received early funding from the MIT Energy Initiative in 2012. The three co-founded the company after proving the concept could work at industrial scale.

Via Separations spent two years proving their technology at a pulp mill in Canada, running continuously without interruption. That real-world success convinced investors including Aramco Ventures and Marathon Petroleum Corporation to back the company's expansion into much larger markets.

The company completed a pilot project at a major refinery last year and now has about $80 million in total funding. Their modular systems can enhance efficiency and unlock additional capacity in existing facilities without requiring complete overhauls.

The Ripple Effect

Industrial separation processes happen in nearly every manufacturing sector, from food production to pharmaceuticals to petroleum refining. Each facility that adopts this technology doesn't just cut its own energy bills and emissions. It proves to competitors and peers that cleaner alternatives actually work at commercial scale.

The investment from major energy companies like Aramco signals something important: even traditional fossil fuel giants see the business case for dramatically more efficient operations. When a Saudi Arabian energy company and a major US petroleum corporation both invest in the same clean technology, it suggests the economics have shifted.

Manufacturing accounts for roughly a third of global energy consumption, and separation processes represent a significant chunk of that demand. Technology that cuts that energy use by 90% could make a measurable dent in industrial emissions while saving companies money.

Why This Inspires

This story shows how patient investment in early-stage research can blossom into commercial solutions that tackle massive environmental challenges. The technology started with a university grant in 2012, took five years to develop into a company, spent two more years proving itself in the field, and now stands ready to scale globally.

It also demonstrates that sustainability and profitability can align perfectly. Companies aren't adopting this technology out of charity. They're doing it because using 90% less energy for the same process saves money while meeting emissions goals.

The path from lab to commercial success took over a decade, but Via Separations now has the funding and proof points to accelerate adoption across multiple industries that desperately need cleaner alternatives.
