Available to the general public. Mining activities in the Philippines pose various environmental impacts and threaten the surrounding ecosystem especially from the release of toxic heavy metals. The green technology, phytoremediation has been shown to remove heavy metals from tailings material and therefore could be viable solutions to the problem. In this study, viability of employing the waste treatment technique for industrial application was conducted by setting up a phytoremediation protocol for field application where heavy metal (Arsenic and Copper) contaminated adsorbents, i.e. coco peat and nanofiber membrane, used for treatment of wastewater are also included. Biodegradation of spent coco peat and nanofiber membrane was performed considering that adsorbed heavy metal is only released for phytoremediation upon degradation of the said adsorbents. This was carried out with the mixture of mine tailings and compost (100:0, 80:20 and 60:40 w/w ratios for eight weeks) to get the best ratio of tailings mixture for phytoremediation. The 60:40 tailings mixture was chosen as phytoremediation medium based on the weight loss of degraded coco peat since it showed 15% degradation after eight weeks. Biodegradation of spent nanofiber membrane was implemented in the phytoremediation set up for ten weeks. Two species of ferns- Pteris vittata and Pityrogramma calomelanos were used for the treatment of mine wastes- tailings, coco peat and nanofiber membrane. Phytoremediation procedure was established by investigating planting parameters namely; plot height - (9 cm and 15 cm) and planting distance- (15 cm and 20 cm) for a period of five months.
