Boreal Resin-microbe Synergy: a Universal Bio-technological Framework for Microplastic Remediation Across Salinity Gradients
Summary
This paper is a duplicate of ID 386, presenting the same proposed framework for using Finnish boreal pine resin combined with microbial consortia to capture and biodegrade microplastics in water, with biomethane as an energy byproduct. The concept aims to provide a scalable, carbon-neutral remediation approach validated against industrial and natural Finnish water systems. Both entries describe the same proposal.
Abstract:The global escalation of microplastic (MP) pollution in aquatic ecosystems demands scalable, carbon-neutral, and economically viable solutions. This study investigates an integrated remediation framework utilizing Finland’s boreal forest side-streams—specifically Scots Pine (Pinus sylvestris) resin—as a bio-adhesive matrix for MP sequestration. Following capture, a specialized microbial consortium (bacteria, fungi, and molds) is employed for enzymatic mineralization. We evaluate the chemical affinity of Abietic Acid for MP entrapment and the metabolic pathways of Ideonella sakaiensis for PET degradation. Benchmarked against the Viikinmäki (Helsinki) industrial model and the Lake Saimaa ecosystem, this framework provides a dual-track strategy for both industrial wastewater and natural water protection. The system achieves high-affinity sequestration (>94% for PET) and transforms environmental pollutants into energy sources (Biomethane) via anaerobic digestion, aligning with the EU Green Deal mandates.
