Plastic Waste Output must be supported by a specification, representative quality checks, batch records and a complete material reconciliation. Production statistics and throughput help establish whether reported quantities are technically credible.
What does good Plastic Waste Output mean in RecyClass Sorting Process?
A visually clean bale is only part of the picture. The output needs a defined specification, documented quality, traceability, weight and an identified customer. Its quantity must be consistent with input waste, other waste, residual waste and stock.
RecyClass also examines production statistics and process throughput, because quality and quantity records should provide a coherent account of how the sorting facility operates.
1. Plastic Waste Output is the result of sorting, but remains waste
Sorting Process ends with plastic waste prepared for further recycling. The material may be sold as PET, PE or PP bales or another fraction, but its status and documentation must reflect the actual process.
Sorting certification does not mean that Recycled Output, as defined in Recycling Process Certification, has already been produced.
2. The quality specification should be unambiguous
The Sorting Process Audit Scheme requires a waste specification linked to the characteristics of the plastic waste. It should cover at least the target polymer, colour, waste origin and maximum contamination level required by the scheme.
This gives the customer and sorting facility a common understanding of quality and provides a reference for output checks.
3. Quality control requires representative sampling
The sorting facility should have a system for monitoring and validating the quality of its plastic waste.
RecyClass requires representative samples from the output stream and records of the sampling conditions.
The assessment focuses on contaminants, including non-plastic materials and non-target plastics, and on colour where relevant.
4. A test result must be recorded
Even an experienced operator cannot replace documented checks. Records should show at least when the sample was taken and the result.
In practice, it is also useful to record the batch number, person carrying out the check, sample weight, contamination share and decision on the batch.
5. Volume reconciliation connects the input to all outputs
RecyClass describes Sorting Process volume reconciliation as an overview of all material flows during the evaluation period. The reconciliation should be reasonably accurate and discrepancies must be explained.
Comparing input waste only with plastic waste is insufficient. Other waste, residual waste, stock and any other significant process flows also need to be included.
6. A simple reconciliation example
A sorting facility receives 1,000 tonnes of input waste. It produces 420 tonnes of plastic waste, 250 tonnes of paper, metal, glass and other waste, and 280 tonnes of residual waste; 50 tonnes remain in stock.
The total should reconcile with the input, taking account of actual weighing methods and justified differences. If 120 tonnes are missing without explanation, the auditor will ask what caused the discrepancy.
7. Production records show how the line operates
Sorting centres keep records of operating time, input waste quantities and plastic waste produced. These data support both reconciliation and assessment of actual operating capacity.
If the system reports 20,000 tonnes of output despite short operating hours and low throughput, a plausibility check may identify a need for further explanation.
8. Actual and design throughput support process traceability
The Audit Scheme requires material movement through the sorting process to be documented together with process parameters, including actual and design throughput in tonnes per hour.
Every hour does not need to be identical. Reported production volumes must, however, be technically credible in light of the installation's capabilities.
9. Management should use production statistics
RecyClass requires reports at least monthly that can support process improvement and show, for example, production levels, downtime and contamination levels.
This changes the role of audit data: they should form part of process management rather than being assembled once a year solely for certification.
10. Output traceability must also reach the customer
Transfer-of-ownership records should include customer details and the weight and type of plastic waste. The relevant evidence of material transfer should be retained.
Quality control without identification of the specific batch and customer does not provide complete traceability.
11. Common mistakes at sorting facilities
Typical problems include inconsistent specifications, unrepresentative samples, results recorded without a batch number, missing data on other waste, reconciliation limited to plastics, unexplained losses and stated capacity that does not match line operating time.
Each of these issues can weaken the credibility of the output even when the final bale looks clean.
FAQ
Is Plastic Waste Output already Recycled Output?
No. Plastic Waste Output is the result of Sorting Process and still has to undergo further recycling.
Can quality control consist only of visual checks?
Visual analysis may be one method, but the system must be suitable, documented and based on representative samples in accordance with the scheme.
Does volume reconciliation cover plastics only?
No. It should show all significant material flows during the evaluation period.
Does the auditor check line throughput?
Actual and design throughput are part of process documentation and may be used to assess whether reported volumes are credible.
Does a sorting facility need monthly production reports?
The Audit Scheme provides for production statistics to be used in reports for management at least monthly.
