Food Grade Recycled Plastic: FDA No Objection Letter Process and Requirements

## Food Grade Recycled Plastic: FDA No Objection Letter Process and Requirements

### Introduction

The FDA No Objection Letter (NOL) is the primary regulatory pathway for using recycled plastics in food contact applications in the United States. This article explains the NOL process, requirements, and timelines.

### NOL Process Overview

**Step 1: Challenge Testing**
– Surrogate contaminant introduction
– Food simulant exposure
– Migration analysis
– Contaminant clearance calculation

**Step 2: Application Submission**
– Chemistry data package
– Process description
– Challenge testing results
– Proposed use conditions

**Step 3: FDA Review**
– Pre-submission meeting (recommended)
– Formal review (6-12 months)
– Information requests
– Final determination

### Testing Requirements

**Surrogate Contaminants**:
– Volatile organic compounds
– Semi-volatile organic compounds
– Heavy metals
– Pesticides

**Food Simulants**:
– 10% ethanol (aqueous foods)
– 50% ethanol (alcoholic foods)
– Vegetable oil (fatty foods)
– Tenax (dry foods)

**Migration Limits**:
– Cumulative estimated daily intake (CEDI)
– Threshold of regulation (TOR) analysis
– Safety assessment

### Common Pathways

**Primary Recycling**:
– Post-industrial scrap (simpler pathway)
– Same-process recycling
– Limited reprocessing steps

**Secondary Recycling**:
– Post-consumer material
– Physical reprocessing (melting, extrusion)
– Challenge testing required

**Tertiary Recycling**:
– Chemical recycling (depolymerization)
– Monomer purification
– Repolymerization to virgin-quality

### Timeline and Costs

**Timeline**:
– Preparation: 6-12 months
– FDA review: 6-12 months
– Total: 12-24 months

**Costs**:
– Testing: $50,000-150,000
– Consulting: $30,000-80,000
– FDA fees: $0 (currently no user fee)
