What is MF003?

MF003 is a white granular solidification reagent designed to rapidly convert liquid and semi-liquid waste streams with variable solids content into a dry, granular solid with no free liquids. It is used to treat drilling mud, drilling sludge, tunneling spoil, TBM and EPB slurry, HDD drilling fluids, wastewater sludge, and other high-moisture residues.

The technology helps waste generators meet EPA Paint Filter Test criteria by transforming wet waste into a stackable, landfill-compatible material that is easier to handle, transport, stockpile, and dispose of.

MF003 delivers rapid in-situ solidification in less than 30 minutes, producing a stable granular residue with minimal sensitivity to ambient humidity. The technology has passed microtoxicity testing and is designed for tunneling, drilling, environmental, and wastewater treatment operations.

What problems does MF003 solve?

Managing liquid waste, drilling mud, sludge, and wet spoil from tunneling, drilling, wastewater operations, stormwater sediment removal, and hydro excavation activities is costly, logistically complex, and increasingly regulated. Conventional solidification methods such as lime, sawdust, drying pits, or evaporation ponds often increase waste mass, occupy valuable operational space, and delay disposal workflows. Inadequately treated waste can also release free liquids during handling and transport, creating operational challenges and disposal restrictions.

MF003 addresses these challenges from generation to final disposal. Applied at typical dosages ranging from 0.1–1.0%, MF003 rapidly transforms liquid and semi-liquid waste into a stackable material in under 30 minutes. The treated material reduces free liquid release and improves handling, transport, stockpiling, and disposal operations.

The result: simplified waste management operations, improved material handling conditions, approximately 30% lower disposal costs, and up to 67% lower logistics costs compared with conventional solidification methods.

How does MF003 work?

With low dosage rates typically ranging from 0.1–1.0% relative to waste mass, MF003 is applied directly onto wet material and mechanically mixed using excavators or similar equipment.

The reagent allows rapid solidification, transforming sludge, drilling fluids, slurry, wet spoil, and liquid waste streams into stackable material suitable for transportation and disposal operations.

MF003 creates a stable material that reduces free liquid release during handling and supports easier operational management of wet waste streams.

How to apply MF003

1. Analyze the waste material

Evaluate the waste type, water content, density, and handling requirements to define the appropriate MF003 dosage. Typical application rates generally range from 0.1–1.0%.

2. Apply MF003 directly onto the wet material

Spread the reagent directly over sludge, drilling fluids, spoil, sediments, or liquid waste streams in pits, tanks, ponds, containers, stockpiles, or staging areas.

3. Mechanically mix the material

Mix using excavators or similar equipment to ensure uniform distribution and full contact between MF003 and the wet material.

4. Allow solidification

MF003 allows rapid solidification, transforming the waste into a stable and stackable material in less than 30 minutes.

5. Transport, stockpile, or dispose

Once solidified, the material can be handled using conventional equipment for transportation, temporary stockpiling, or disposal operations.

Where MF003 is used

MF003 can be applied across tunneling, drilling, environmental, stormwater, hydro excavation, and wastewater operations
that generate liquid waste, sludge, slurry, sediment, or wet spoil requiring rapid solidification and easier handling.

Micro-tunneling operations

Solidifies wet excavated material and slurry after excavation activities to simplify transportation, stockpiling, and disposal operations.

EPB-TBM tunneling operations

Helps manage wet spoil and tunneling slurry by transforming liquid material into stackable solids for easier operational handling.

Water-based drilling fluids

Rapidly solidifies spent water-based drilling fluids prior to transportation and disposal.

Stormwater and wastewater pond sediments

Solidifies wet sediments and dredged material removed from ponds and containment systems prior to transportation and disposal.

Water-based drilling cuttings

Applied after primary solids-control equipment to improve handling and transportation conditions of wet cuttings.

Sewage sludge

Helps transform sewage sludge into stackable material suitable for handling, transport, and disposal operations.

Hydro excavation mud

Helps manage hydro excavation mud by reducing free liquid and improving handling conditions during transportation and disposal activities.

Supports operational waste management

MF003 is designed for liquid immobilization and operational solidification of wet waste materials without functioning as a contaminant treatment technology.

The reagent rapidly reduces free liquids and improves handling conditions, helping operators simplify transportation, stockpiling, and disposal activities for difficult wet waste streams.

Final disposal pathways and material classification should always follow local regulations and project-specific environmental requirements.

MF003 in the field

Tunneling Waste

Rapid Slurry Solidification

MF003 rapidly solidified tunneling slurry and wet spoil during the NorthConnex Tunnel Project in Australia, transforming liquid waste into stackable material for easier transportation and disposal while improving excavation logistics. The solution achieved solidification within minutes, generated approximately $200 per tonne in savings, reduced dependency on vacuum trucks, and produced landfill-compatible material.

HDD Slurry

Cost Reduction in Drilling Logistics

MF003 transformed HDD drilling slurry into stable, stackable material for safer handling, transportation, and disposal operations while reducing dependence on long drying cycles. The technology achieved solidification in less than 30 minutes using typical dosage rates of only 0.1–1.0%, helping reduce disposal logistics costs by up to 67% and disposal costs by around 30%.

Disposal and compliance references

Liquid waste solidification projects should be evaluated according to waste classification requirements, free-liquid criteria, transportation conditions, disposal regulations, and site-specific operational requirements. MetaFLO Technologies can provide technical guidance, dosage recommendations, and application protocols for sludge, slurry, drilling waste, and liquid waste solidification operations.

EPA Paint Filter Test (Method 9095B)

The United States Environmental Protection Agency (EPA) uses the Paint Filter Liquids Test (Method 9095B) to determine the presence of free liquids in waste materials for landfill disposal and waste classification purposes. Materials that release free liquid during the test are considered liquid waste.

EPA Test Method:
9095B Paint Filter Liquids Test

Common evaluation criteria:

Absence of free liquids
Non-leaching solid material
Landfill disposal suitability

Landfill disposal & free-liquid restrictions

Many North American landfill regulations restrict or prohibit the disposal of waste containing free liquids. Paint Filter Test criteria are commonly referenced to evaluate waste acceptance for landfill disposal and transportation.

Typical operational objectives:

Reduction of free liquids
Improved stackability
Reduced leaching risk
Lower transportation costs
Landfill-compatible solid material

Liquid waste handling

Drilling mud, slurry, sludge, and wet residues may be classified as liquid waste depending on their composition and free-liquid content. Solidification technologies are commonly used to simplify handling, transportation, and disposal logistics.

Common operational sources:

HDD drilling fluids & TBM/EPB slurry
Wastewater sludge
Stormwater sediments

The Paint Filter Test (EPA Test Method 9095B) is an EPA procedure used to evaluate whether a waste material contains free liquids. In the test, the material is placed into a standardized filter for a short period of time to verify if liquid separates from the waste. Materials that release free liquid during the procedure may not be accepted for certain landfill disposal operations. MF003 is designed to help immobilize free liquids and support compliance with Paint Filter Test requirements.
