Recycling Contamination Audit Checklist [FREE PDF]

Recycling contamination audits are essential to maintaining the quality of recovered materials and complying with EPA RCRA 40 CFR 261 waste characterization requirements that distinguish recyclable commodities from regulated solid waste. Contamination rates above acceptable thresholds can cause entire loads to be rejected by material recovery facilities (MRFs), reclassified as solid waste, and disposed in landfills—triggering potential Clean Air Act and RCRA compliance implications. Regular cont

  • Frequency: Monthly
  • Estimated Time: 45-60 minutes
  • Role: Recycling Coordinator
  • Total Items: 37
  • Compliance: EPA RCRA 40 CFR 261 - Identification and Listing of Hazardous Waste, EPA RCRA 40 CFR 262 - Standards Applicable to Generators, EPA Clean Air Act 40 CFR 60 Subpart WWW - Landfill Emissions Standards, State Solid Waste Regulations - Recyclable Material Quality Standards, DOT 49 CFR 173 - Shippers General Requirements for Shipments

Audit Setup & Sampling Procedure

Document the audit setup, sampling methodology, and initial load observations before detailed inspection.

  • Was the audit sample selected using an approved random sampling methodology?
  • Is the minimum sample size of 200 lbs (or facility-required minimum) being audited?
  • Are auditors equipped with appropriate PPE including gloves, safety glasses, and hi-vis vest?
  • Has the source route or collection zone been recorded for traceability purposes?
  • Is a calibrated scale or weight measurement method available for this audit?

Paper & Fiber Stream Assessment

Evaluate the quality and contamination levels within the paper and cardboard recycling stream.

  • Is the paper/fiber stream free of food-soiled or heavily contaminated paper products?
  • Is corrugated cardboard (OCC) broken down flat and free of excessive tape and staples?
  • Are non-recyclable paper materials (wax-coated, thermal paper, carbon paper) absent from stream?
  • What is the estimated paper/fiber contamination rate for this sample?
  • Are shredded paper materials contained in clear bags or otherwise managed to prevent sorting issues?

Plastics Stream Assessment

Identify accepted plastic resins and document contamination from non-program plastics and other materials.

  • Are only program-accepted plastic resin types (e.g., #1 PET, #2 HDPE) present in the plastics bin?
  • Are plastic bags and film plastics absent from the rigid container recycling stream?
  • Are plastic containers emptied and free of significant liquid or food residue?
  • Are non-recyclable plastics (Styrofoam/EPS, PVC pipe, toys) absent from the recycling stream?
  • What is the estimated plastics stream contamination rate for this sample?

Metals & Glass Stream Assessment

Evaluate metal and glass recyclables for program compliance and contamination levels.

  • Are aluminum and steel cans present and free of excessive food residue?
  • Are non-program metals (scrap metal, wire, appliances, propane tanks) absent from the stream?
  • Is glass (if accepted) limited to food and beverage containers only?
  • Are sharp metal objects (knives, needles, blades) absent from the recycling stream?
  • Are aerosol cans present, and if so, are they empty and caps removed?

Hazardous & Prohibited Materials Detection

Identify and document any hazardous or prohibited materials incorrectly placed in the recycling stream.

  • Are household hazardous waste materials (batteries, paint, chemicals) absent from the recycling stream?
  • Are electronic waste items (phones, computers, batteries) absent from the recycling bin?
  • Are medical or pharmaceutical waste items absent from all recycling containers?
  • Are food waste and organic materials absent from dry recycling containers?
  • If hazardous materials were identified, have they been segregated and reported per facility protocol?
  • Document all prohibited or hazardous items found during this audit:

Contamination Rate Calculation & Measurement

Record weight-based contamination measurements to calculate the official contamination rate for this audit.

  • What is the total weight of the recycling sample audited (lbs)?
  • What is the total weight of contaminants removed from the sample (lbs)?
  • What is the calculated overall contamination rate for this load (%)?
  • Does the contamination rate exceed the MRF contract threshold requiring load rejection?
  • What are the top 3 contaminant categories identified in this audit?

Corrective Actions & Program Recommendations

Document corrective actions, community education needs, and program improvement recommendations based on audit findings.

  • Are immediate corrective actions required based on the contamination levels found?
  • Have findings been communicated to the relevant collection route supervisor?
  • Is enhanced community outreach or education recommended for the source zone?
  • Are changes to accepted materials lists or collection protocols recommended?
  • Document all recommended corrective actions, outreach initiatives, and follow-up items:
  • Has this audit report been filed in the compliance records system for regulatory review?
