The invention introduces a bioremediation system utilizing a plant-derived biomimetic nano-framework known as Renewable Artificial Plant for In-situ Microbial Environmental Remediation (RAPIMER). This framework is designed to efficiently adsorb and biotransform contaminants, including persistent organic pollutants (POPs) such as PFAS compounds. RAPIMER is derived from lignocellulosic sources, making it a cost-effective and sustainable solution for environmental remediation.
Pollution from persistent organic chemicals poses significant health risks and challenges for global remediation efforts. Traditional methods are complex, costly, and often result in secondary pollution. PFAS, a type of POP, is particularly difficult to degrade and is linked to serious health issues. Current remediation methods are expensive and unsustainable, highlighting the need for innovative, integrated, and cost-effective solutions.
The invention offers a plant-based substrate that supports microbial growth for contaminant removal, specifically targeting POPs like PFAS. This substrate includes natural biopolymers such as lignin and cellulose, which enhance the expression of enzymes necessary for pollutant degradation. The system can be employed for bioremediation in various environments, utilizing a range of microbial strains, including fungi and bacteria.
The invention defines terms and conditions for its application, emphasizing the versatility of the RAPIMER framework in adsorbing various contaminants. It specifies the use of cellulosic biomass from diverse plant sources and details the process of passing contaminated fluids through the RAPIMER substrate using pressure systems. The framework's adsorbent properties enable it to hold contaminants on its surface, facilitating efficient remediation.
RAPIMER is capable of removing a wide range of contaminants, including PFAS compounds, heavy metals, and dyes. Its application spans across contaminated waters, soils, and other environments. By leveraging microbial strains such as white rot fungi and bacteria, the invention provides a sustainable and efficient method for environmental cleanup, aligning with the growing need for eco-friendly remediation technologies.
