Natural environment biodegradation: Prosol-adjustable biodegradation, quick softening after contacting water; other-quick degradation, embrittlement and fragmentation. 5. Safe to land: Prosol can increase the cohesiveness, air permeability and water holding capacity of soil, not harmful to land; others not harmful to soil and plant. 6. Safe to ocean: Prosol-softened, losing strength and dissolved in water after contacting water, not harmful to marine lives and birds; others-harmful to marine life and birds.
