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.

*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 vary depending on moisture content, clay fraction, mineralogy, particle size distribution, spoils rheology, operational objectives, and required spoils handling characteristics. See product specifications bellow for details.

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.
