From the experience gained with the market application of the UNI/PdR 115:2021, last 18th July, the national voluntary standard
“UNI 11951:2024 Management of recycled wood for the production of wood-based panels” was published.
This document defines the
requirements for the use of pre-consumer and post-consumer recovered wood material suitable for the production of wood-based particle and fiber panels.
The requirements are applicable to all wood-based panel manufacturing plants that use wood waste,
regardless of the type of panel that will be made.The standard defines the use of pre-consumer and post-consumer recovered wood material suitable for the production of wood-based panels, regarding:
- the characteristics of recycled wood waste;
- the procedures;
- treatments and controls on recycled wood waste and on the finished product.
Regarding the
RAW MATERIAL, the standard defines the requirements that recycled wood have to meet in terms of:
- size
- origin
- quality (with examples of excluded product categories).
Adequate
controls on acceptance of materials must verify input materials into the plant, non-compliant material managing and inspections recording.
The checks to be carried out along the production chain are also specified to guarantee:
- a proper supplier quality assessment (e.g.: waste analysis certifying its non-dangerousness, correct attribution of European Waste List codes);
- compliance with the Requirements for the Analysis of various parameters such as: Arsenic, Lead, Cadmium, Chromium, Copper, Mercury, Zinc, Chlorine, Fluorine, Pentachlorophenol, Benzo(a)pyrene (creosote), in order to demonstrate the non-hazardousness of the waste.
The document moreover provides periodic checks on the
PRODUCTION PROCESS by sampling the mixture of incoming material and on the
FINISHED PRODUCT, by specifying frequency of analyses, recording methods, parameters to be analysed and their limits.
The standard also specifies the sampling and analysis methods to be applied to assess the
SUPPLIERS OF THE FINISHED PRODUCT. For a deeper and more detailed analysis of the topics covered by this standard, please refer to the full reading of the document which can be acquired on the UNI website at the link:

What Reference Practices are?
Reference Practices introduce technical prescriptions or sectoral application models of specific standards when there are no national, European or international standards or draft standards on the subject. They may contain good practices already in use in citizen/consumer services, sectorial applications of existing specifications, industry specifications, protocols for the management of proprietary marks, locally tested management models, national level adoptions of CWAs (CEN Workshop Agreements, reference documents of particularly innovative character).
