PECB ISO-9001-Lead-Auditor Question Answer
You are conducting an ISO 9001 audit of a Materials Recycling Facility (MRF). The company
processes waste plastics into raw material for plastic bottle manufacturers. You reach the manual
picking line where operators are removing contaminant materials from incoming products, such as
plastic bags, plastic film and badly contaminated items that would compromise the recycling process.
You interview the line supervisor.
You: "Why are these plastic items being rejected at this stage?"
Auditee: "They do not meet our processing standards."
You: "What is the reason for that?"
Auditee: "These items are likely to damage the machinery down the line. They can also
compromise our quality standards. We need to protect our reputation for good quality output
materials."
You: "What happens to the rejected items?"
Auditee: "Some get melted down in another process later on and some are disposed of as waste
products that cannot be recycled."
You: "What happens to the waste products?"
Auditee: "I'm not sure. I suppose they go to landfill."
After further auditing, you have gathered additional evidence.
