Overview
IEC TR 62635:2012 provides comprehensive guidelines for the exchange of end-of-life (EoL) information between manufacturers and recyclers of electrical and electronic equipment (EEE), focusing on optimizing recyclability and recoverability rates. Published by the International Electrotechnical Commission (IEC), this technical report establishes a common methodology for EEE manufacturers and recyclers to enable efficient, environmentally conscious design (ECD) and treatment of products at their end-of-life phase. The methodology helps stakeholders comply with international, regional, and national regulations, and supports effective resource efficiency throughout the electronics product lifecycle.
Key Topics
-
EoL Treatment Process Principles:
- Defines generic steps in EoL treatment: pre-treatment, material separation, energy recovery, and disposal.
- Emphasizes compliance with regulations and the need to address safety and environmental concerns.
-
Provision of Product Information:
- Details the information manufacturers should provide, including product identification, potential hazards, and part identification for dismantling.
- Stresses the importance of clear labeling, documentation, and the use of standardized material classifications (e.g., IEC 62474).
-
End-of-Life Treatment Information:
- Outlines what recyclers need to inform manufacturers regarding specific processing capabilities and requirements.
- Covers feedback mechanisms so manufacturers can factor actual recycling practices into product design and recyclability rate calculations.
-
Calculation of Recyclability and Recoverability Rates:
- Presents methods to calculate the proportion of a product’s mass that can be recycled or recovered.
- Describes how to document and communicate these rates, aiding transparency and improvement in EEE design and recycling procedures.
-
Criteria for Dismantling and Selective Treatment:
- Provides guidance on identifying parts for reuse, selective dismantling (for hazard mitigation), and single-material parts to improve recycling efficiency.
- Addresses challenges related to parts that are difficult to process and require special handling.
Applications
IEC TR 62635:2012 is applicable across all sectors producing or handling electrical and electronic equipment, including:
Related Standards
-
IEC 62474 - Material Declaration for products of and for the electrotechnical industry:
Ensures standardized reporting of materials in EEE and supports the identification needed for efficient end-of-life treatment.
-
IEC 62430 - Environmentally conscious design for electrical and electronic products:
Details broader principles and practices for ECD, of which EoL management and recyclability rates are key components.
-
ISO 22628 - Road vehicles - Recyclability and recoverability calculation method:
Offers complementary methodology specifically for automotive products, referenced as a precedent for recyclability calculations.
-
Various regional WEEE (Waste Electrical and Electronic Equipment) directives:
Local legislation often implements the processes and definitions outlined in IEC TR 62635 for waste handling and recovery.
