The SlurryCarb® Process
EnerTech's SlurryCarb® process is an environmentally sound method for achieving 100% beneficial reuse of biosolids and other high-moisture feedstocks. The process converts biosolids into a renewable solid fuel.

The SlurryCarb® technology is a biosolids recycling solution as well as an opportunity to protect our environment by replacing fossil fuels with a renewable energy source. Biosolids are brought to a central manufacturing facility where they are processed as a pumpable slurry, creating savings in capital and operating costs. The biosolids slurry is continuously pumped and pressurized above its saturated steam pressure to maintain a liquid state throughout processing. By avoiding evaporation, thermal energy inputs for the evaporation of water are minimized. As a result, the SlurryCarb® process requires substantially less energy than traditional drying methods. The entire process produces about twice as much energy as it consumes

Upon reaching the desired reaction pressure and temperature, the biosolids undergo a molecular reconfiguration. The cellular structure of the biosolids ruptures and carbon dioxide gas splits off, a step called decarboxylation. This reaction significantly reduces the size and improves the uniformity of the biosolids molecules. The reacted product becomes hydrophobic and can be mechanically dewatered to greater than 50% solids. This dewatered, reacted product is concentrated in carbon, and over 80% of the original water present in the biosolids is removed without evaporation.

The reacted, dewatered product is dried to form a fuel that has a heating value of approximately 6,500 to 7,000 Btu/lb. This fuel, called eFuel, is exported to a customer and utilized as a renewable fuel.

The need for environmentally and economically sound alternatives to traditional biosolids recycling methods is becoming increasingly evident. EnerTech's SlurryCarb® technology offers a low-cost, sustainable, and environmentally friendly solution that has already gained the company widespread interest and support.
