Other significant players were Embark Ventures, The Grantham Foundation for the Protection of the Environment, Massachusetts Clean Energy Centre (MassCEC), Safar Partners, Climate Investment and Marathon Petroleum Corporation. The venture will now use the fresh capital to scale its business, apart from financing the deployment of a modular filtration platform into the refining and chemical sectors.

Via Separations’ expertise lies in providing filtration systems designed to lower energy use in industrial separation processes by up to 90%, apart from significantly reducing emissions in industrial processing.

Electrifying Heat-based Separation

“Via Separations is a membrane technology company driving the transition from expensive, energy-intensive thermal separations to efficient, lower-cost filtration. Via is operating at commercial scale, delivering value to industrial customers today with no green premium. Via Separations is a membrane technology company driving the transition from expensive, energy-intensive thermal separations to efficient, lower-cost filtration. Via is operating at commercial scale, delivering value to industrial customers today with no green premium,” the start-up explained itself through these words.

Via electrifies heat-based separation with modular filtration systems that integrate directly with existing industrial equipment, reducing the energy required for chemical separations in the process.

“These thermal separation steps account for roughly 12% of global energy use, driving significant fuel and steam demand across industrial separations. By replacing them with a mechanically driven membrane process, Via’s system can reduce energy use at the separation step by up to 90%, delivering lower operating costs, higher uptime, and a more flexible pathway to energy efficiency and electrification,” Via Separations remarked.

Via Separations’ membrane technology uses up to 90% less energy than traditional evaporation or distillation because it is a physical separation, rather than a thermal process. In the start-up’s language, “these membranes work like a coffee filter or pasta strainer, but for chemicals.”

These materials are made of a unique source called graphene oxide (GO), which is extremely stable in nature, ensuring the membranes withstand high temperature and corrosive process conditions, where typical polymer membranes don’t work at all. Via Separations has already proven the membrane technology at commercial scale in the pulp and paper sector, approaching two years of continuous operation at a Canadian pulp mill. The start-up is now expanding the technology’s deployment into refining and chemicals, with hundreds of millions of dollars of capital projects in the commercial pipeline. In 2025, the company also completed a pilot at a major Gulf Coast refinery.

The Via Ecosystem

Through its filtration systems, the start-up is driving both bottom- and top-line improvements for its industrial customers, reducing energy costs, apart from providing operational flexibility and de-bottlenecking production.

The start-up has tuned its durable graphene oxide membranes to perform challenging industrial separations across markets. The start-up continued, “Complete system integrates Via membranes into customers’ existing processes in a compact footprint. Via systems deliver quality separations while reducing costs, energy, and production bottlenecks.”

A very good example of Via Separations’ industrial innovation has been its first commercial-scale Black Liquor Concentration System (BLCS), which is operational at the International Paper site in Grande Prairie, Alberta, Canada. The global pulp and paper industry, known for annually producing over 400 million tonnes of paper, packaging, and tissue from wood fibres and recycled materials, faces one challenge: black liquor recovery. We are talking about the most capital and energy-intensive component of a Kraft pulp mill, which burns waste cooking liquor (12%-15% solids) in a specialised boiler to produce energy (steam/electricity) and recover inorganic cooking chemicals.

To address the challenge, Via has created Black Liquor Concentration System (BLCS), which concentrates weak black liquor before evaporation, translating to cost savings and operational benefits for pulp mills.

“Via’s Black Liquor Concentration System (BLCS) displaces steam use in evaporators using a reverse-osmosis-like process to directly remove hot, clean water from weak black liquor (WBL). The compact BLCS integrates into existing mill footprints to concentrate WBL up to 40% solids,” the start-up said.

Via Separations’ efficient concentration process eliminates production bottlenecks and reduces the energy consumption of black liquor concentration by up to 50%. The technology, if widely deployed, will help pulp mills realise additional free cash flow in the millions of dollars per year.

In the petrochemical industry, despite heavy crudes becoming more prevalent, refineries are facing limited capabilities when it comes to processing the fuel due to the size of the vacuum distillation unit (VDU). To solve this, Via filtration system is increasing the VDU capacity, reducing costs and energy consumption while unlocking additional heavy crude processing capacity.

Via’s innovations have been expanding in the chemical manufacturing industry as well. Acid processing is a large market that touches both the chemicals and refining sectors. Knowing the potential, Via is looking to provide on-site processing of sulfuric acid, reducing costs and emissions while enabling recovery of acid-soluble oils (ASOs).
