Inorganic & Mineral-rich Sludges

Thousands of tons of inorganic sludge are generated every day — ProtectGD transforms this environmental challenge into geopolymer raw material.

Problem / Context

ProtectGD is interested due to the very large volume of emissions generated at water treatment plants, mining operations, and industrial facilities.

Market size

Market size

  • Ho Chi Minh City & Southern Economic Zone: 800 – 1,200 tons/day (~0.35 million tons/year, estimated) — sludge from Thu Duc Water Treatment Plant, BOO; industrial park sludge.
  • Vietnam: 6,000 – 9,000 tons/day (~2.5 million tons/year, estimated) — water supply sludge, wastewater treatment sludge, filter cake
  • Globally: ~250,000 tons/day (~90 million tons/year, estimated) — mostly landfilled; increasing environmental pressure.

Technical

Technical specifications

  • Rich in silica, alumina, and metal oxides — suitable precursors for semi-dry geopolymer technology.
  • Diverse sources: water treatment plant sludge, wastewater treatment sludge, inorganic industrial sludge, filter cake, sludge cake
  • Alkaline environments activate the fixation of heavy metals into the aluminosilicate network, transforming intractable sludge into construction aggregate.

ProtectGD Solution

Inorganic sludge is a promising but often wasted semi-dry geopolymer raw material. ProtectGD optimizes its processing formula to transform wastewater sludge, industrial sludge, and filter cake into aggregates and building components without high-temperature firing — effectively addressing environmental concerns while creating low-carbon building materials.

BRING VALUE

Economy

Input materials are almost free or have a processing fee (US$15–60/ton) → saving on material costs while generating a stable cash flow from processing services for water treatment plants and industrial zones.
