A CIRCULAR BIOECONOMY APPROACH IN PHYTOREMEDIATION TECHNOLOGY FOR HEAVY METAL CONTAMINATED SOIL

Abstract

Phytoremediation has received wide attention in remediating heavy metals from contaminated soils because it has been shown to be an efficient, economical, and environmentally friendly technique. Nevertheless, the deficiency in efficient management and post-phytoremediation treatment disposal and handling methods for heavy metal-contaminated biomass has impeded the advancement and implementation of this technology. The article has synthesized and analyzed data on phytoremediation technology from publications over several years, using specialized search engines with keywords before filtering out irrelevant information based on titles, abstracts, and keywords of each article. Based on an overview of phytoremediation technology, post-harvest biomass treatment methods such as pyrolysis, extraction, nano-material synthesis are advocated towards sustainability objectives, aligning with a circular bio-economic paradigm aimed at heavy metal reuse. This represents a promising green strategy to tackle future challenges related to fuel scarcity, necessitating ongoing further research model deployment to expand industrial applications.
