GRAN-SORB Environmentally Friendly Oil AbsorbentGRAN-SORB Is a industrial absorbent made from 100% recycled post-consumer paper waste.  This environmentally-responsible product absorbs oils, solvents, lubricants, coolants, water and most non-aggressive liquids on contact.  Because Gran-sorb is created using fibrous sludge waste from select paper mills, it is safe for both environmental and employee use.  Gran-sorb has a weight to-weight absorbency of one-to-one:  eg:  30lbs will absorb 30lbs of oil (equivalent to 4 gallons).  Gransorb is 100% silica-free
