Research and development of biodegradation disposal for SBS (Sugi Bark Sorbent)

The research on the practical applications of SBS (Sugi Bark Sorbent) which was initiated in 1997 realized a waste material recycled product using 100% natural materials with reduced environmental loads which is comparable to commonly used petroleum products in terms of performance and cost, and reached the stage of commercial production in 2000. For the purpose of reducing total environmental loads in the oil recovery, we investigated biodegradation treatment as a disposal method of SBS after use (after adsorbing oil). It was confirmed that the oil content was reduced from 10000 ppm to 2000-5000 ppm after 1 to several week-period in a biodegradation experiment using Bunker C in the bark compost.
