DECOMPOSITION Co., Ltd.

A Complete Microplastic Solution from Detection to Removal

Specialization

Microplastic Detection
Enzyme-Based Fluorescent Biosensor
Plastic-Degrading Microorganisms

Keywords

Microplastic Fluorescence Detection Kit
Nanoplastic Detection
Plastic-Degrading Enzymes

DECOMPOSITION develops 5mm Lab, a full-cycle microplastic management solution covering detection, measurement, and removal.
Its core product is the Microplastic Fluorescence Detection Kit, MFDK, an enzyme-powered biosensor platform for rapid microplastic detection.
The technology uses food-grade plastic-degrading microorganisms and enzymes derived from Korean fermented food sources.
The solution is designed for water quality monitoring, wastewater treatment validation, consumer product testing, and microplastic-free certification.

(1) Problem Definition / Development Background

Microplastics and nanoplastics are emerging as major environmental and health risks.
Existing FT-IR and Raman-based methods are expensive, slow, and limited in detecting nanoplastics below 5 μm.
European brands and water facilities face new compliance pressure from REACH, UWWTD, and national regulations in France and Germany.
Large-scale monitoring requires faster, cheaper, and more accessible testing tools.

(2) Value Proposition / Solution

DECOMPOSITION provides a rapid, enzyme-powered fluorescence detection method for microplastic monitoring.
The MFDK platform enables high-throughput analysis using standard microplate readers.
It reduces testing time from several days to within hours and lowers cost compared with conventional spectroscopy-based analysis.
The solution helps public agencies, brands, testing labs, and manufacturers prepare for stricter microplastic regulations.

Nanoscale Detection: Detectable size limit of approximately 50 nm, compared with legacy methods limited to around 5 μm.
Fast Analysis: Provides analysis within 5 hours, compared with 3–7 days for conventional methods.
Cost Reduction: Target cost of €50–100 per sample, compared with €500–1,200 for legacy testing.
Accessible Equipment: Uses standard microplate readers instead of bulky, high-cost spectroscopy systems.
Food-Grade Bio Platform: Based on GRAS-level safety microbial strains and enzymatic technology.

Developed 5mm Lab as a microplastic detection and management platform.
Secured patents related to plastic-degrading microbial strains and plastic-degrading enzymes.
Selected for the national TIPS program.
Designated as a Promising Small & Strong Enterprise by Pohang City.
Participating in K-water supply and wastewater testbed program.
Built an R&D team integrating biotechnology, materials science, product manufacturing, and branding expertise.

(1) PoC Progress

DECOMPOSITION is preparing a strategic PoC rollout for Europe.
Planned PoC areas include:
- Urban water cycle monitoring.
- UWWTD fourth-stage treatment validation.
- B2B consumer product certification testbeds.
The company is open to free sample screening, European field pilot opportunities, and global scientific collaboration.

(2) Global Expansion

Europe is the primary entry market due to tightening microplastic regulations.
The company proposes a dual-engine European entry strategy:
- The Netherlands: Lab-based scientific validation and urban water cycle monitoring.
- Germany: Regulatory certification, consumer retail, and B2B data services.
Target customers include municipal water authorities, wastewater treatment plants, cosmetics and hygiene brands, FMCG manufacturers, environmental testing labs, and private certification bodies.
