Microbially treated peat-cellulose fabric as a biodegradable oil-collection cloth.
The aim of this work was to study the use of a fully biodegradable peat-cellulose fabric as a first aid in collecting and removing spilled oil. The fabric itself was made from entirely biodegradable natural components. Another aspect investigated was whether drying microbial suspension--specifically enriched for the degradation of oil hydrocarbons while maintaining a high survival rate and rapid initial growth--to the fabric would improve the degradation of absorbed oil along with the fabric. The results show that the oil absorption capacity of the biodegradable fabric was comparable to commercial products, and that the oil absorbed to the fabric degraded readily when incubated at various conditions. The microbial inoculum enhanced the degradation rate to some degree in sand, but in garden soil no significant difference existed. It was concluded that an oily fabric can be disposed of by biodegradation, e.g., by composting, but that a microbial inoculum is not essential for this purpose.
