Certificate for materials

CERUB certificate

CERUB certification for sustainably recycled tyre rubber

CERUB certification guarantees that the materials derived from recycled tyres are produced and delivered responsibly. CERUB certification can be granted to organisations that manufacture and distribute End-of-life tyres derived rubber materials.

The CERUB certification assures the buyers and users that the tyre material is

a) processed under controlled conditions
b) documented for safe and secure use
c) safe for health and environment in the designated use

CERUB certification is verified by accredited 3rd party verification and is based on a self-declared certification system. Certification is valid for 3 years.

What is a sustainably recycled tyre rubber?

Materials that can hold a CERUB certification are tyre shreds, rubber granulates, and powder. No additional substances are added to the material, nor it is treated chemically. It means that the material is a pure tyre. With this, we can make sure the quality of the produced material is controlled and known.

Only tyre material of which end-use application is known can hold a certification. That means that the certificate is always specific for a defined use. With this, we make sure the material meets the quality requirements for safe use in the particular use.

Only those tyre materials of which the production chain fulfils the CERUB certification criteria can hold a certificate. The production chain includes the sourcing, storing, and sorting of end-of-life tyres and the production and distribution of the produced tyre materials.

Certified production chain

The CERUB certification system is built for tyre recycling companies and other companies producing and delivering rubber materials derived from end-of-life tyres. By using the CERUB label, the organisation commits to executing a responsible and transparent production chain. The chain includes several stages from sourcing of old tyres to delivery of the produced rubber materials.

Sourcing

In sourcing, the end-of-life tyres are collected from collection points, such as tyre workshops, tyre shops, motor vehicle repair shops and motor vehicle dismantlers. The collection points collect disused tyres from motorists. In the phase of sourcing, quality control is conducted to detect foreign materials and other deviations in the collected batch.

Storing and sorting

The collected end-of-life tyres are transported from the collection point for storing. Before the tyres are processed into shreds, granulates or powder, the tyres are sorted by the type of tyre. In storing and sorting, quality control is conducted to detect foreign materials and other deviations in the stock.

Processing

The sorted end-of-life tyres are delivered to the treatment facility for processing. The processing includes size reduction, a treatment designed to reduce a tyre into smaller pieces or particles. One or several different technologies can be used. In processing, the particle size reduces, but the physical and chemical composition remain equivalent to virgin tyre. In processing, quality control is conducted to ensure that the produced rubber material meets the defined set of quality criteria, the material quality specifications.

Distribution

After processing, the produced tyre derived rubber is delivered for end-use with applicable user information. Material distribution to the markets can happen by the processing organisation, retailer or other actor selling or otherwise making the material available for end-use. Using the material is not part of the certification system.

Quality assurance and safety management

Every stage of the production chain includes quality control and safety management. The purpose of safety management is to ensure that the organisations’ operations are safe for the workers, the public and the environment. With quality control, the organisation makes sure that the produced tyre derived rubber meets the required quality. The material must meet the specifications set for the particular end-use purpose.

Principles of Certification

The principles and criteria set in CERUB specify the conditions for granting a certification and allowing the use of the CERUB label. The CERUB label guarantees that the end-of-life tyre derived rubber material holding the label is produced and supplied by the following six principles: 

Principle 1

Compliance with law and regulations

Principle 2

Traced material flows

Principle 3

Availability and validity of CERUB information

Principle 4

Enhancement of occupational health and safety

Principle 5

Good environmental performance

Principle 6

Quality assurance and applicable user information
