# Recycle — Execution Flow

### Overview

A recycle operation moves through several deterministic steps executed by protocol contracts.

These operations convert native fees and accounting units into recycling activity and provider rewards.

***

### Step 1 — Inventory Provisioning

Inventory providers supply tokens through the Inventory interface.

Tokens are transferred into the ledger and converted into accounting units.

These units represent execution capacity.

***

### Step 2 — Execution Request

A user submits a recycle request through the Recycle interface.

The request specifies:

• asset\
• native service fee\
• beneficiary address

The engine calculates accounting unit consumption.

***

### Step 3 — Fee Routing

The service fee is routed through the Protocol Fee Router.

Example fee rails:

Ops rail\
Sponsor rail\
Fund rail\
Recycle rail

Each rail receives a predefined share of the service fee.

Distribution is defined using parts-per-million parameters.

***

### Step 4 — Recycling Engine Execution

The recycling engine performs several operations:

• consumes accounting units\
• updates recycling weight\
• records execution telemetry\
• allocates rewards

Example engine event:

```
Recycled(
 beneficiary,
 token,
 nativePaidWei,
 unitsConsumed,
 recycleRailWei,
 weightMinted
)
```

***

### Step 5 — Weight Accounting

The engine tracks protocol participation using a weight system.

Key variables:

```
weightOf(user)
totalWeight
```

Weight represents a participant’s share of recycling activity.

Higher participation produces greater weight allocation.

***

### Step 6 — Reward Allocation

A portion of the service fee is routed to inventory providers.

Rewards accumulate inside internal accounting balances.

Providers may withdraw these balances through the operator interface.

***

### Step 7 — Proof Reporting

The protocol allows reconstruction of recycling activity through report generation.

Reports are created using:

• contract event logs\
• ledger state reads\
• fee routing events

Available formats include:

CSV\
JSON\
HTML

Reports operate within fixed block windows to ensure deterministic reconstruction.

***

### System Guarantees

The recycling infrastructure operates under deterministic constraints.

All operations follow defined on-chain rules including:

unit conversion\
fee routing\
weight minting\
reward allocation

The interface provides proof of execution but does not create ownership, entitlement, or guarantees.
