The application of phytoremediation method to wastewater treatment of nickel ore extraction industry based on the expert stakeholder perspective

Abstract

The use of chemical-based wastewater treatment method may cause harm to the environment. The aim of this research is to identify the flow application of wastewater treatment using phytoremediation method and summarize the perspective from stakeholders regarding the application based on long-term and short-term categories. In-depth interview was done with expert stakeholders from the sectors of government, private and academics. Subsequently, the scenario of wastewater treatment and the result of phytoremediation research that will be applied on nickel ore extraction industry were confirmed. Finally, a summary of the in-depth interview is shown on a form of a figure. The result shows that this method application needs effort and decision making from the company's part that become the short-term issue for the company. However, on long-term side, phytoremediation is able to benefit the environment, social, and economy.
