From Durian Depot to Recycle Depot: How simpliDepot Can Manage a Material Recovery Business

If you run a recycling depot — buying scrap plastic, metal, or paper from collectors, sorting it, and selling it to processors — your daily operation looks remarkably like a durian collection point. Dozens of suppliers arrive with varying quantities and quality. You weigh, grade, pay out, store, and eventually sell to buyers who want an invoice. The paperwork is the same kind of mess.

simpliDepot was built first for durian depots in Thailand. But the system underneath is generic enough that adapting it to a material recovery facility (MRF) is a configuration exercise, not a rebuild. Here is how the pieces map — and what would need to be customized.

The Workflow Is the Same

At its core, every commodity depot — agricultural or recycled — runs the same pipeline:

  1. Intake: A supplier arrives. You weigh the material and record who brought it, what it is, and at what price.
  2. Grading: Quality is assessed (clean vs. contaminated plastic, pure vs. mixed metal, dry vs. wet paper).
  3. Inventory: The material sits in your yard, tracked by lot, type, and grade.
  4. Sale: A processor or exporter buys a quantity. Oldest stock goes out first.
  5. Invoice: The buyer gets a document. The collector gets a payout record.

simpliDepot handles all five stages with locked price snapshots, automatic FIFO allocation, and concurrency-safe invoice numbering. Every one of those features solves the same problem in a recycling business that it solves at a durian depot.

Terminology Swap: What Changes in Configuration

simpliDepot (Durian) Recycling Adaptation
Commodity variety (Monthong, Chanee) Material type (PET plastic, HDPE, OCC cardboard, aluminum)
Grade A / B / C Quality tier (Clean, Lightly Contaminated, Rejected)
Farmer / supplier Collector, scrap dealer, waste picker
Buyer Recycling mill, processor, exporter
Payout price per kg Collector payout rate per kg (set daily or weekly)
Sale price per kg Processor purchase price per kg

The price snapshotting feature is actually more important in recycling, where commodity prices move daily. When a collector arrives Monday morning and a price dispute comes up three weeks later, the locked record in simpliDepot is the answer — no re-arguing what the rate was on that day.

What Would Be Customized

A few recycling-specific rules sit outside the vanilla durian build and would be configured or lightly extended:

1. Multi-material intake per trip

A collector typically brings several materials in one truck — say, 80 kg PET bottles, 40 kg HDPE drums, and 15 kg aluminum. In the durian version each lot is a single variety. For recycling, the intake form would be extended to accept multiple material lines per visit, each with its own weight, grade, and price snapshot.

2. Tare and moisture deductions

Recycling yards commonly apply a moisture deduction (e.g., wet paper gets 10% docked) or tare weight for packaging. simpliDepot’s weight handling is configurable; deduction rules per material type would be added to the intake flow so the payout is calculated on net weight automatically.

3. Contamination rejection

Some loads are rejected outright. The system would add a “rejected” status at the grading step, generating a rejection record rather than a lot in inventory. This is a small workflow addition rather than a structural change.

4. Daily market rate integration

Recycling commodity prices follow market indexes (e.g., Thai Recycling Exchange, regional scrap prices). The existing price catalog supports effective-dated rates — a manager updates the rate each morning and all intakes that day lock that price. For depots that want automatic feeds, an API integration to the price source can be added.

What You Get Out of the Box — Without Any Changes

  • Full lot traceability: Know exactly which collector’s material ended up on which processor’s truck.
  • FIFO inventory: Oldest stock is always allocated first — prevents old bales from sitting in the corner while new material ships.
  • Dispute-proof payouts: The price paid to each collector is a permanent record, locked at the moment of intake.
  • Role-based access: Weighing staff, cashiers, yard managers, and administrators each see exactly what their role requires.
  • Live dashboards: Real-time stock on hand by material type and grade, sales pipeline, and revenue — no end-of-day exports.
  • Sequential invoicing: Gap-free invoice numbers even when multiple cashiers are billing buyers at the same time.

The Short Answer

simpliDepot is not durian-specific — it is a depot management platform that was deployed first for durian. The data model (supplier → lot → grade → FIFO inventory → buyer → invoice) is commodity-agnostic by design. A recycling depot has the same operational shape and the same pain points: price disputes, no lot traceability, manual invoicing errors, and generic ERP that staff abandon within a month.

Adapting simpliDepot for a recycling business is mostly a renaming and configuration exercise, with a handful of recycle-specific additions (multi-material intake, tare deductions, rejection flow) that are straightforward extensions of the existing pipeline.
