Wastewater Heat to Clean Energy: SHARC Tapped by U.S. National Lab

SHARC Energy (OTCQB: INTWF) has been chosen by the U.S. National Laboratory of the Rockies to supply technology for an advanced wastewater energy recovery project that targets lower building emissions and energy costs.
The project will demonstrate how SHARC’s systems can capture heat from wastewater and reuse it for space heating, cooling, and hot water in high‑performance and low‑carbon buildings.
Why this project stands out
The National Laboratory of the Rockies is a leading U.S. Department of Energy research center focused on energy systems and real‑world deployment of clean technologies.
Being selected by this lab gives SHARC important third‑party validation and puts its wastewater heat‑recovery solution into a high‑visibility demonstration that can influence future building and district‑energy projects.
What SHARC’s technology will do
SHARC’s system is designed to tap into warm wastewater streams—such as sewer and greywater lines—and extract thermal energy that would normally be wasted.
That recovered heat can then be used to efficiently provide heating and cooling, helping buildings cut utility bills and reduce greenhouse gas emissions compared with traditional fossil‑fuel systems.
Why this matters for clean energy and investors
The project will gather real performance data on energy savings, emissions reductions, and economic benefits, creating a blueprint that cities, utilities, and developers can replicate.
If results are positive, SHARC could see growing interest in its technology for municipal infrastructure, district‑energy networks, and large commercial developments looking to meet net‑zero or low‑carbon goals.
Quick snapshot of SHARC Energy
SHARC Energy focuses on wastewater energy recovery systems that turn sewers into a renewable thermal resource for buildings and districts.
The company positions wastewater heat as one of the largest overlooked clean‑energy sources in cities, with existing deployments already operating in North America and Europe.
