Using Cocopeat for Treating Septic Tank Effluent

David Robbins of RTI International in the U.S. will test a septic tank biofilter made from cocopeat, which is a readily available byproduct of coconut processing, for its ability to decompose human waste and produce effluent that can be used for crop fertilization and irrigation. If successful, the cocopeat biofilter could be produced locally and aid in solid waste treatment and water conservation efforts.
