Application of Rice Husk Fiber to the Vegetation Media

Urban Farm DB summary

In South Korea, this study evaluated whether rice husk fiber — derived from the biorefinery process used for rice husk silica extraction — could substitute for cocopeat, the major component of vegetation media used in artificial greening such as rooftop gardens, testing samples made with OCC or ONP pulp. Higher rice husk fiber content produced bulkier, weaker vegetation media, though water-holding capacity and disintegration resistance were little affected, and no effect on conductivity change was detected. The study concludes that substituting rice husk fiber for cocopeat is possible with optimized application practice.
