Waste Classification & Full Standard Disposal Process For Medical Electrode Production Workshops

Published: JULY 27, 2026 - Shanghai Zhichen Medical Technology Co., Ltd.

Medical electrode cleanroom production generates multiple types of waste including contaminated defective products, expired finished electrodes, filter scraps and general packaging waste. All waste must be strictly classified, sealed stored and handed over to certified medical waste treatment vendors, with complete transfer records reserved for ISO13485 and market supervision audits.

1 Four Core Waste Categories For Electrode Factories

1.1 Infectious Medical Waste (Yellow Special Sealed Bags)

Unsealed defective electrodes after EO sterilization

Used biological indicator test strips

Cleanroom dust wiping cloth contaminated by gel

Sampling test scraps contacted with human simulation fluid

Storage rule: Independent locked waste room, sealed double yellow bags, marked production date and waste category, no mixed stacking with other garbage.

1.2 General Production Scrap (Black Bag)

Unused intact substrate rolls, leftover PET film, clean release liner scraps, empty raw material plastic barrels without gel residue. Can be recycled by regular industrial waste companies after sorting.

1.3 Expired Finished Medical Electrodes (Yellow Infectious Waste)

Electrodes exceeding shelf life shall be fully sealed in yellow medical waste bags, prohibited from dismantling gel layer in general area to avoid microbial cross-contamination risks.

1.4 Cleanroom Consumable Waste (Grey Bag)

Replaced HEPA filters, used cleanroom caps/shoe covers, non-contaminated dust wiping paper, no infectious hazards, delivered to industrial waste recycling station.

2 Workshop Waste Storage Environmental Requirements

Independent waste storage room separated from clean production zone

Ventilation and anti-mosquito disinfection facilities installed

Ground seamless epoxy anti-seepage floor for easy disinfection washing

Waste storage period shall not exceed 48 hours before transfer

3 Standard Transfer & Filing Process

Weigh each batch of infectious waste, fill transfer manifest with factory name, waste type, weight, date

Seal all yellow waste bags with plastic ties before loading

Only cooperate with local health bureau certified medical waste disposal enterprises

Keep transfer receipts, weighing records and vendor qualification certificates for at least 5 years

4 Forbidden Waste Behaviors (Audit High-Risk Points)

Forbid mixing infectious electrode scraps with domestic garbage

Forbid pouring residual hydrogel into common drainage pipeline

Forbid selling expired electrodes to small workshops for reprocessing

Forbid storing infectious waste over 3 days without transfer

5 ISO13485 Audit Matching Document List

Waste classification operation SOP

Daily waste storage disinfection log

Medical waste vendor qualification certificate copy

Continuous monthly waste transfer manifest archive

Employee waste classification training records

Summary

Standardized medical waste classification and transfer management eliminates factory environmental supervision risks and ISO13485 audit non-conformities, which is a mandatory daily management item for all disposable medical electrode production enterprises.
