The wastewater reprocessing startup ZwitterCo has raised $33 million to scale up its chemically engineered membrane water filtration expertise to assist industrial firms and massive farms recycle wastewater from their methods, permitting them to make use of much less contemporary water.
“The goal for us is to maximize reuse, so that you can limit the amount of freshwater consumption,” CEO and cofounder Alex Rappaport instructed CNBC in a video interview. “We’re going to enable a future of water abundance.”

That’s essential now as a result of local weather change is more and more making contemporary water a scarce commodity. Currently, 37% of the United States and 44% of the decrease 48 states are in a drought, in keeping with the National Integrated Drought Information System.
“The world is getting hotter and, in many places, drier. Demand for water outstrips supply in much of the United States, including the Colorado River Basin, which is at its lowest level in 1,000 years,” Jason Pontin, a companion at DCVC, the enterprise capital agency that’s main this funding spherical, defined in a publish about their funding.
“But Americans also waste a lot of water: every day, industrial facilities in the U.S. discharge 255 billion gallons of wastewater into public waterways,” stated Pontin, who can also be the chair of ZwitterCo’s board. “Most of that is treated through chemical, physical, or biological means, but it’s still not pure enough for industrial reuse. If it were, then facilities wouldn’t discharge it.”
That’s the issue ZwitterCo is fixing with its membrane expertise product of so-called “zwitterionic copolymers” — therefore the corporate’s identify — which was first developed by the chemical engineering professor Ayse Asatekin at Tufts University.
What is a zwitterionic membrane?
Decades value of earlier efforts to develop water filtration expertise for industrial use instances have been stymied by an issue known as “membrane fouling,” which implies the pores of the filter get so clogged up so often that it takes an excessive amount of time to wash them.
That’s very true of the type of supplies that should be taken out of wastewater from an industrial manufacturing unit or massive agricultural farm, like fat, oils and greases.
ZwitterCo’s expertise, the zwitterions, are so good at sucking up water, they really wick moisture out of the air, Rappaport instructed CNBC.
A filtration membrane seems to be one thing akin to a sponge if you zoom in actually shut, and it is the width of that sponge, or the peak of the pores, that is the toughest half to maintain clear. But the ZwitterCo membrane’s pores act as kind of vacuums for the water, pulling the water molecules out of the oils.
“Because the membrane is so, so, very hydrophilic from these zwitterions, you’re able to operate for years in environments that another membrane would be ruined in hours,” Rappaport instructed CNBC. That’s “because you’re constantly able to sort of re-wet, re-hydrate the surface and regenerate it back to the starting performance.”

What’s actually crucial to profitable clients is that the system can save clients cash along with water, in keeping with Rappaport. Exactly how a lot cash and water relies on the farm or industrial facility.
“In the absence of having efficient tools to extract all of those contaminants out of the water, you’re sort of stuck.” Other choices embrace hauling it away, dumping it down the drain, or coordinating with regulators to unfold some portions of the waste out over the land, Rappaport instructed CNBC. ZwitterCo’s expertise reduces these prices.
For Solugen, a Houston-based firm that manufactures chemical substances and supplies utilizing enzymes, ZwitterCo’s water filtration system has let it recycle about 10 million gallons of water within the final yr, in keeping with an estimate from cofounder and CTO Sean Hunt.
“Our first manufacturing facility, Bioforge 1, is a zero discharge facility in that we do not have air or wastewater emissions. ZwitterCo’s membranes are a key technology in our toolbox,” Hunt instructed CNBC. “Our process water recycling loop is north of 20 gallons per minute, and it goes through various membrane, recovery, and reuse steps to conserve and recycle our process water back to the front-end of Bioforge 1.”

In many instances, similar to in manure digestate therapy, meat and poultry therapy, dairy waste water, and bioprocessing functions, the fabric that’s filtered out with ZwitterCo’s membranes will be resold as fertilizer or feedstocks, creating a brand new income stream.
“So in the meat and poultry industry, the fats and oils we take out can be sold in pet food. In the bio processing industry, the cellular material that we can take out can be sold as an organic feedstock to help serve as a high protein diet for the livestock. In the manure industry, the organics that get taken out can be a fertilizer,” Rappaport instructed CNBC. “So the goal is create value on both sides of the membrane.”
ZwitterCo was launched in 2018 and subsisted on grants for its first yr and a half, together with $1.25 million from the Department of Energy. Rappaport and his co-founders, Christopher Drover and Chris Roy, primarily spent the early years determining find out how to take the analysis from Asatekin’s lab and flip that right into a product that may very well be manufactured and commercialized at scale.

The $33 million ZwitterCo is saying Thursday brings complete funding raised to $44 million and will enable ZwitterCo to finish the construct out of a 30,000 sq. foot facility in Woburn, Massachusetts. There are at present 50 full-time staff and whereas the corporate is making income from 16 purchasers, it is not but turning a revenue.
This funding can even go partly towards hiring extra folks to work with industrial purchasers to tailor the ZwitterCo set up to the wants of the shopper. The value of putting in a ZwitterCo water filtration system varies tremendously relying on the client, however can run between 5 and seven figures, Rappaport instructed CNBC. This is on par with the infrastructure enhancements that factories and farms make frequently, he stated.
