Boreal Resin-microbe Synergy: a Universal Bio-technological Framework for Microplastic Remediation Across Salinity Gradients
AI summary Read the abstract
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.

Boreal Resin-microbe Synergy: a Universal Bio-technological Framework for Microplastic Remediation Across Salinity Gradients
AI summary Read the abstract
This paper proposes a theoretical framework for removing microplastics from water using pine resin from Finnish boreal forests as a natural adhesive to capture plastic particles, followed by microbial digestion to break them down — with the byproduct being biomethane for energy. The concept claims over 94% removal efficiency for PET plastics and positions the approach as carbon-neutral and aligned with EU environmental policy. While the framework is promising in concept, it appears to present a design proposal rather than empirical experimental results.
