Waste Codes: Where do they come from and why are they so important?
Proper classification of waste is the foundation of responsible management of used electrical and electronic equipment (WEEE). In this article, we explain what waste codes are, why they matter for your business and how to avoid mistakes that could lead to extra costs or legal issues.
What are waste codes and where do they come from?
On December 29, 2014, the Journal of Laws published a regulation introducing the Catalogue of Waste, which established a detailed division of waste into groups, subgroups and types. Each type of waste generated by a business must be correctly classified based on its origin.
The current catalogue includes twenty main waste groups. For example, group 15 covers packaging waste, while group 20 includes municipal waste. Hazardous waste requiring special handling is marked with an asterisk (*).
Why is correct waste classification so important?
Assigning the correct waste code is a crucial step in the waste management process. Proper classification affects several key issues. First, it enables cooperation with entities that collect and process waste, which must hold the appropriate permits.
Second, it affects disposal costs, as choosing a non-standard code may significantly limit access to processing companies, often leading to inflated service rates. Third, it ensures compliance with current regulations, as incorrect classification may result in penalties during inspections or audits in the BDO.

Examples of proper waste classification for electrical and electronic waste
In some cases, waste can be classified in multiple ways depending on how it was generated. It’s worth analyzing specific cases to better understand this issue.
Classification of toners and cartridges
Used toners and cartridges containing electronic components should be classified under code 16 02 14 if submitted whole as used devices.
However, if they have been removed from used equipment, for example during the disassembly of a printer, code 16 02 16 should be applied. A common mistake is using code 08 03 18, which applies only to the “contents” of these toners (i.e., the waste powder), and not to whole cartridges.
Classification of electrical and electronic equipment
Equipment originating from households, such as a printer handed over to a Municipal Selective Waste Collection Point, should be labeled with code 20 01 36.
The same printer, but coming from a company, for example, used office equipment, must be classified under code 16 02 14.
Current challenges related to battery waste codes
The rapid development of technology means that regulations do not always keep pace with changes.
Currently, there is no separate code for lithium-ion batteries, which are increasingly common on the market.
European Parliament and Council Regulation (EU) 2023/1542 on batteries and waste batteries, which will apply directly in all member states from August 18, 2025, explicitly distinguishes and names these batteries.
However, work on implementing a new waste code for this type of battery is still ongoing. For now, we must continue using code 16 06 05 – Other batteries and accumulators.
Summary: Why is it important to pay attention to waste codes?
Proper waste classification is crucial for several reasons.
First and foremost, it affects the costs of waste disposal, as an incorrect code can significantly increase fees. Additionally, it determines processing options since only certain entities hold permits for specific types of waste.
It is also worth mentioning that during an audit, it is possible to verify whether the waste codes are correct, whether the costs incurred are appropriate to the market situation and whether the waste records in the BDO system are maintained in compliance with the regulations.
Incorrect classification and recording of waste can also lead to penalties being imposed on an unaware entrepreneur.
