MF BioDry™ is a family of engineered biodegradable reagents developed specifically for EPB-TBM tunneling operations requiring spoil solidification, free-water reduction, and improved spoil handling efficiency. The technology helps reduce spoil flowability, improve transportability, and support temporary spoil storage under variable tunneling conditions.

MF BioDry™ works through engineered moisture interaction mechanisms designed to reduce free-water expression and improve spoil consistency during EPB-TBM operations. The result is improved excavated material handling, reduced spoil flowability, better hauling conditions, and more efficient spoil logistics.

MF BioDry™ 001 is optimized for lower free-water environments and cohesive spoil matrices with higher clay content, while MF BioDry™ 002 was developed for more variable and challenging tunneling conditions, offering broader moisture handling capability and improved free-water control.

Unlike traditional mineral-based additives, MF BioDry™ is an organic-based reagent specifically engineered for EPB-TBM spoil solidification applications requiring safer and more environmentally conscious technology. The platform may help reduce material consumption, improve spoil consistency, reduce free-water release, and simplify spoil handling operations while using biodegradable components designed for tunneling applications.

MF BioDry™ technologies are typically evaluated for wet EPB-TBM spoil streams where moisture conditions create flowability, free-water release, hauling difficulties, and spoil storage challenges.

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