DRACO

Sludge Reduction, Zero Energy Bill

Fueled by heat you already have.

DRACO HTC can position to integrate seamlessly with waste heat generating infrastructure like incinerators (Waste-to-Energy Plants), coal-based power plants, & cement plant by utilizing waste heat/steam without additional energy input.

DRACO

DRACO HTC is engineered to operate under high temperatures and pressures, making it a perfect match for sites with surplus steam. Facilities such as incinerators (Waste-to-Energy), coal-fired power plants, and cement kilns can supply waste heat or steam directly to the HTC process. This eliminates the need for external energy input and creates a highly efficient, self-sustaining system.

Dryer

Following DRACO treatment, sludge with improved dewaterability can be processed through existing dryers. These dryers can tap into the same waste steam sources—especially from incinerators—to accelerate drying. This synergy shortens drying time, reduces operating costs, and minimizes maintenance issues, all without requiring additional energy sources.

03

Evaporator

After mechanical dewatering (e.g., via filter press), the centrate produced can be treated using the site's evaporator. Instead of treating or discharging this liquid waste separately, steam from the incinerator is repurposed to evaporate the centrate water. This turns a potential waste stream into vapor, improving resource efficiency and lowering disposal costs.

One & Only Zero Energy Sludge Reduction Facility

Seohae Green, South Korea

Project Objective: Sludge Volume Reduction without Sticky Phase

The Seohae Green Project represents the first full-scale deployment of DRACO HTC integrated with waste heat recovery from an onsite incinerator. This retrofit was strategically implemented to improve sludge drying efficiency, ensure operational reliability, and streamline sludge management without adding energy burden.

Installation of DRACO resulted in:

  • Mitigating frequent shutdowns and excessive maintenance costs due to dryers

  • Improved sludge volume reduction

  • Adaptability to various sludge characteristics

  • Shorter drying time

  • Reduced operational costs

Waste-to-Energy Plant (Incinerator) of Seohae Green, South Korea

Steam Usage: 0.21 kg Steam/kg Sludge (21 tons/day)

Steam usage based on the following:

Feed Sludge Water Content: 84%
Sludge Temperature: 20°C

** Actual steam consumption may vary depending on the characteristics of the input sludge **

Sludge Treatment Capacity: 100 ton/day

Smart Integration of Existing Resources

Seohae Green Project maximized cost-efficiency by integrating DRACO with a combination of existing infrastructures & targeted upgrades:

  • DRACO was integrated into an existing incinerator, using waste steam to power HTC process

  • Achieved improved sludge volume reduction without increasing the facility’s energy footprint

  • Shorter drying time reduced energy demand

  • Lower operational costs due to reduced energy use and efficient heat reuse.
