7 Steps to Audit Your Restaurant’s Foodware for Sustainability and Compliance

A foodware audit is the systematic review of all packaging and disposable items used by a restaurant operation, identifying which items meet sustainability and compliance requirements, which don’t, and what procurement decisions support the operation going forward. For restaurants in regulatory jurisdictions (California SB 54, Washington EPR programs, various state PFAS bans, growing local plastic restrictions), the audit isn’t optional — compliance verification depends on knowing exactly what’s in use.

For B2B restaurant operations committed to compostable programs and regulatory compliance, this 7-step framework guides systematic foodware audit.

Step 1: Inventory All Foodware Currently in Use

Catalog every packaging and disposable item across the operation:

Front-of-house items:
– Beverage cups (hot, cold, multiple sizes)
– Cup lids
– Straws
– Stir sticks
– Napkins (cocktail, dinner, custom)
– Utensils (forks, spoons, knives)
– Sugar packets, condiment packets
– Branded paper goods

Takeaway items:
– Food containers (multiple sizes, hot/cold variants)
– Container lids
– Bags (bag sizes, with/without handles)
– Carryout bag handles
– Sauce cups and lids
– Wraps and inner packaging

Back-of-house items:
– Food preparation containers
– Storage bags
– Wrapping materials
– Disposable gloves
– Cleaning consumables

Specialty items:
– Catering specialty packaging
– Special-event items
– Holiday/seasonal packaging

For each item, document:
– Specific SKU/product description
– Supplier
– Material type (paper, plastic, fiber, etc.)
– Volume (units per month)
– Application

This baseline inventory is the foundation for the audit. Skipping items because they “don’t matter” creates compliance gaps later.

Step 2: Identify Material Composition for Each Item

For each inventoried item, document the actual material composition:

Conventional plastic identification:
– PET, PP, HDPE, PS, PVC, etc.
– Petroleum-derived plastic origin

Compostable material identification:
– PLA, PHA, PBAT
– Bagasse fiber, sugarcane fiber
– Bamboo
– Kraft paper, coated paper
– Cellulose film

Hybrid material identification:
– Paper with plastic coatings (poly-coated paper, PFAS-coated paper)
– Bioplastic blends (PLA-PBAT)
– Composite materials

The material composition determines compostability, recyclability, and compliance status. Suppliers should provide composition documentation for each SKU; if they can’t, that’s a procurement concern.

Step 3: Verify Compostability Certification per SKU

For items currently labeled “compostable,” verify actual certification:

BPI registration check. Search the BPI online certification database (bpiworld.org) for the specific SKU. Brand-level certification doesn’t transfer to all SKUs.

ASTM D6400 / D6868 compliance. Verify the SKU meets US industrial composting standards.

EN 13432 compliance. Verify European standard if relevant for product origin.

TÜV OK Compost certification. Industrial or HOME variant — relevant for international procurement.

CMA registration. Compost Manufacturing Alliance acceptance for items deemed acceptable by composting facility operators.

For items claimed as compostable but not actually certified, the gap requires either supplier verification or sourcing alternative.

Step 4: Verify PFAS-Free Status for Grease-Resistant Items

Grease-resistant compostable items have historically used PFAS chemicals. State PFAS bans (California AB 1200 in particular) prohibit PFAS in food packaging:

Grease-resistant items requiring PFAS verification:
– Pizza boxes
– French fry containers and bags
– Burger wrappers
– Hot food containers with grease barriers
– Bakery items contacting fattier baked goods
– Microwave popcorn bags

For each grease-resistant item, request PFAS-free documentation from the supplier. Acceptance criteria:
– “PFAS-free” written documentation
– Test results showing PFAS levels below regulatory thresholds (typically 100 ppm total fluorine as proxy)
– Supplier attestation regarding manufacturing process

Items without PFAS verification documentation should be replaced with verified alternatives in California-impacted operations.

Step 5: Assess Compliance Status by Jurisdiction

Restaurants operate in jurisdictions with varying compliance requirements:

California SB 54 requirements (effective 2027 with interim milestones):
– All single-use foodware must be recyclable, reusable, or compostable
– Producer responsibility for end-of-life infrastructure
– Producer fee structure based on material type

California AB 1200 PFAS ban (effective 2023 with strengthening through 2026):
– All food packaging PFAS levels at or below 100 ppm total fluorine
– Compliance verification through testing or supplier attestation

Washington EPR (Engrossed Substitute Senate Bill 5022):
– Recyclability and reusability requirements
– Producer fee structure

State plastic bag bans (multiple states).

Local plastic ordinances (multiple cities).

For each jurisdiction the operation serves, identify applicable requirements and document compliance status per SKU.

Step 6: Build Procurement Decision Matrix

With audit data, build the procurement decision matrix:

Items currently compliant + sustainable: Continue current procurement.

Items currently compliant but unsustainable: Plan transition to sustainable alternatives over budget cycle.

Items currently non-compliant: Immediate replacement required for jurisdiction-served operations.

Items with verification gaps: Resolve documentation through supplier or replace if supplier can’t provide.

For each procurement decision, document:
– Current SKU
– Replacement SKU (if applicable)
– Supplier (current and replacement)
– Cost difference
– Operational impact (any)
– Implementation timeline
– Verification documentation requirement

Step 7: Implement Tracking System for Ongoing Compliance

The audit isn’t one-time — compliance requires ongoing tracking:

Quarterly procurement audit. Verify ongoing procurement matches the post-audit decisions; identify any new SKUs added to procurement that need audit verification.

Annual full re-audit. Complete inventory + verification refresh annually. SKUs change, certifications expire or update, regulatory requirements evolve.

Supplier documentation file. Maintain ongoing file of certifications, PFAS-free attestations, and compliance documentation per SKU per supplier.

New item approval process. Before adding any new SKU to procurement, verify against audit framework — material composition, certification status, PFAS verification, jurisdictional compliance.

Regulatory monitoring. Subscribe to regulatory updates from relevant jurisdictions. New requirements emerge; existing requirements strengthen.

Common Audit Findings and Solutions

Typical audit findings across restaurant operations:

Finding: “Compostable” items without BPI certification.
Solution: Either obtain documentation from supplier or replace with certified alternative.

Finding: Grease-resistant items without PFAS verification.
Solution: Replace with documented PFAS-free alternatives. Most major suppliers now offer PFAS-free options.

Finding: Mixed material composition across the SKU portfolio.
Solution: Move toward standardization — fewer materials, fewer suppliers, simpler compliance verification.

Finding: Procurement happens through multiple suppliers without consolidated tracking.
Solution: Consolidate to fewer suppliers; centralize procurement tracking.

Finding: Custom-printed legacy items in conventional plastic.
Solution: Plan custom-print refresh on compostable substrates as inventory cycles through.

Finding: Specialty items (catering, holiday) lack compliance verification.
Solution: Apply same audit framework to specialty SKUs as standard procurement.

What “Done” Looks Like for Foodware Audit

A restaurant operation with completed comprehensive foodware audit:

• Complete SKU inventory with material composition documented
• Per-SKU compostability certification verified
• Per-SKU PFAS-free verification for grease-resistant items
• Jurisdictional compliance status documented per SKU
• Procurement decision matrix with replacement plans
• Quarterly tracking system for ongoing compliance
• New SKU approval process integrated into procurement
• Regulatory monitoring subscription

The audit transforms compliance from reactive (responding to audit requests or regulatory issues) to proactive (knowing the operation’s compliance status systematically). For restaurants in California, Washington, and other jurisdictions with growing compostable packaging requirements, the audit work is the foundation of operational compliance.

The supply chain across compostable food containers, compostable bowls, compostable cups and straws, compostable bags, and compostable cutlery and utensils supports the audit-informed procurement decisions across the restaurant SKU portfolio.

For B2B restaurant operators evaluating audit work, the framework provides the systematic approach that converts a complex compliance landscape into manageable per-SKU decision-making. The audit completes once; the procurement and tracking systems it generates operate continuously, making compliance a routine operational characteristic rather than a recurring crisis.

Verifying claims at the SKU level: ask suppliers for a current Biodegradable Products Institute (BPI) certificate or an OK Compost mark from TÜV Austria, and check that retail-facing copy meets the FTC Green Guides qualifier requirement on environmental claims.
