OUR PROCESS
Northgate Holdings, LLC utilizes a patented process (Patent No.: US 11,767,247 B1) for the solidification and stabilization of non-hazardous sludge, soft and/or wet wastes, and liquid wastes utilizing waste solidification agents, including industrial by-products, pozzolanic agents, and proprietary materials.
Our process consists of a blending of industrial by-products, pozzolanic agents, and proprietary materials by mechanical means with sludges, soft and/or wet wastes, and liquid wastes to produce a solidified and stabilized waste suitable for landfill disposal.
The principal constituents of Northgate Holding’s solidification and stabilization materials consist of a bulking agent, a pozzolanic agent, and Northgate Holding’s proprietary material. Bulking materials are mechanically screened to remove oversized materials that are not beneficial to the waste bulking process. Pozzolanic materials are utilized to act as a siliceous pozzolan and provide structural stability to the solidified material. Northgate Holding’s solidification compositions are formulated for each specific waste stream to assist in the waste stabilization process as needed. Bulking agents, pozzolanic material, and propriety material are added at varying proportions depending on the characteristics of the waste to be solidified. Mix designs are developed and processing equipment systems are designed for specific waste streams, available bulking agents, and available pozzolanic materials for each project location. Waste stabilization mix designs are developed to limit liquid release from the solidified material under pressures developed by burial in a landfill.
Northgate Holding’s process and proprietary materials solidify and stabilize non-hazardous sludge, soft and/or wet wastes, and liquid wastes economically; improve the structural stability of the solidified waste; and limit the liquid release of the solidified waste.
