Beyond Plastic.

A community-owned environmental utility transforming plastic interception into coastal resilience.

Sundarbans Guardian Cooperative (SGC)

Architecture of Recovery.

System Under Stress.

The Sundarbans Guardian Cooperative (SGC) addresses the structural failure of 50 tonnes of daily macro-plastic intake across 54 river systems. This volume endangers the region's primary storm defense.

Strategic Response

Converting an ecological externality into a high-integrity, community-owned infrastructure utility.

Feedstock Origins

Community

Riparian recovery of regional upstream transport debris at tidal confluence points.

Tourism & Marine

Debris from 250k visitors and ghost gear from 25k vessels.

Upstream

Riverine plastic flow mapped from 54 river intake points.

Capturing urban runoff from regional systems (30t daily intake).

Process Flow

The Integrity Chain.

Systematic material and financial flow through institutional checkpoints.

Collection
01

Collection Shed

Material Flow

Aggregation of riparian intercepted debris and cruise vessels waste. Precision sorting of PET and HDPE ensures circular purity.

Governance & Audit

NGO weight verification and stewardship audit. Financial settlement via MFS is recorded directly into the digital ledger.

Hub
02

Khulna Hub

Logistic Consolidation

Regional hub executes high-pressure baling to optimize transport density. QA checks verify material grade against industrial off-take specs.

Governance & Audit

Recycling partner custody management. NGO oversight ensures ISO standards and fair labor compliance across the network.

Processing
03

Dhaka Processor

Transformation

Baled feedstock mechanically recycled into secondary raw pellets. Mass-balance verification ensures material integrity for industrial reuse.

Governance & Audit

Production partner manages commercial settlement and issues digital certificates linking tonnage back to coastal guardian clusters.

SCM
04

Client SCM

Supply Chain Integration

Certified material enters supply chain, enabling precise Scope 3 reporting and verifiable environmental claims for partner brands.

Outcome Reporting

Partner utilizes automated dashboards for attribution. Consumer-facing transparency ensures a defensible circular narrative.
