Solving the Sludge Crisis, Globally and Locally

WETCOAL (Ecozza Green Tech Solutions Private Limited), headquartered in Halol, Panchmahal, Gujarat, is a pioneering cleantech enterprise. We address one of the most critical municipal challenges of modern times: sewage sludge disposal.

Conventional waste disposal techniques—like incineration, landfill dumping, or solar drying beds—are carbon-heavy, land-intensive, and smell-prone. WETCOAL shifts this paradigm. By employing our patented APR reactor engineering, we bypass expensive pre-drying stages, neutralizing pathogens and locking carbon into stable bioproducts.

  • Clean closed-loop engineering
  • Lower greenhouse gas emission profile
  • On-site modular system deployment

Aqua Phase Reforming (APR)

Our core process processes sludge directly at the high-moisture level, using thermodynamic conditions to rearrange organic molecules into stable carbon materials.

No Pre-Drying. Fully Sustainable.

Traditional hydrothermal treatment requires drying the sewage sludge beforehand—a process that consumes massive amounts of energy and produces foul odors.

APR operates directly in the liquid phase under pressurized conditions. This unlocks high thermal efficiency because it prevents the water from vaporizing, retaining latent heat in the reactor loop. The process effectively carbonizes municipal waste in hours.
