Converting wet sewage sludge (~80% moisture) directly into high-value green fuel or agricultural resources with patented, zero pre-drying Aqua Phase Reforming (APR) technology.
WETCOAL, 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, such as 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.
Our core process processes sludge directly at the high-moisture level, using thermodynamic conditions to rearrange organic molecules into stable carbon materials.
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.
Direct collection from Municipal STPs or industrial lagoons at ~80% moisture content.
Thermodynamic carbonization under pressurized liquid phase conditions. Bypasses pre-drying.
Direct clean replacement for lignite coal in industrial boilers.
Nutrient-rich soil conditioner to rebuild agricultural soil health.
We convert municipal liabilities into high-grade industrial and agricultural commodities, promoting a true circular economy.
A premium, solid biofuel generated via APR, presenting a direct, sustainable replacement for fossil lignite coal in heavy industrial applications.
