BIODEGRADABLE SOLUTIONS FOR MODERN EPB TUNNELING OPERATIONS

The MF BioDry™ family was developed to support biodegradable spoils solidification and improved free-water control under variable tunneling conditions. The platform is engineered to reduce free-water expression, improve spoils handling efficiency, support temporary spoils storage, and improve spoils transportability while reducing reliance on traditional mineral-based solidification additives in selected applications.

0.1% to 0.4%

To solidify liquid waste*

*Performance depends on spoils rheology, mineralogy, particle size distribution, moisture content, and overall field conditions.

Sustainable Performance for Modern Infrastructure Projects

The MF BioDry™ family was developed for tunneling contractors seeking:

Improved EPB-TBM muck management efficiency

Biodegradable reagent technology for spoils solidification

Reduced free-water release

Reduced free-water release

Improved excavated material handling

Reduced spoils flowability during transport

Typical dosage rates generally range from approximately 0.1% to 0.4%, depending on moisture content, clay fraction, mineralogy, particle size distribution, spoils rheology, operational objectives, and required spoils handling characteristics.

The MF BioDry™ Family

The MF BioDry™ platform operates through engineered moisture interaction mechanisms designed to reduce free-water expression and improve spoils handling characteristics under EPB-TBM tunneling conditions.

Compared to MF BioDry™ 001, the MF BioDry™ 002 platform provides broader moisture handling capability and improved spoils solidification performance under more variable tunneling environments while maintaining biodegradable formulation characteristics.

MF BioDry™ vs Traditional EPB Spoils Solidification Additives

Unlike conventional mineral-based spoils solidification additives, the MF BioDry™ family was developed specifically for EPB-TBM operations requiring biodegradable reagent technology for projects with environmental or biodegradability-related requirements.

Traditional Additives Common Limitations in EPB-TBM Operations MF BioDry™ Advantage
Lime-Based Powders Dust generation, alkaline handling concerns, and elevated mineral consumption Safe biodegradable
Cement-Based Additives High material consumption and increased spoils mass generation Lower dosage rates under comparable spoils conditions
Sawdust and Organic Absorbents Variable performance under changing moisture conditions More consistent free-water reduction performance
Generic SAP Powders Non-specialized performance for EPB-TBM muck streams Developed specifically for EPB-TBM muck solidification applications

Typical Field Conditions

MF BioDry™ products are typically evaluated for EPB-TBM muck streams presenting:

Environmental or biodegradability-related disposal requirements

Flowable spoils behavior

Free-water release during hauling or stockpiling

Engineering & Operational Considerations

Performance ranges presented throughout this page are intended to support simplified product selection for typical EPB-TBM tunneling conditions.

Moisture content, spoils behavior, clay content, and operational requirements may influence final product performance and dosage rates.

MF BioDry™ products are intended for spoils solidification and free-water reduction in EPB-TBM operations. Final spoils handling, transportation, and disposal requirements remain dependent on project conditions and local regulations.

The MetaFLO technical team can assist in determining which MF BioDry™ platform may be more suitable for specific EPB-TBM muck conditions and operational objectives.
