100 % compostability based on binding test standards to ensure freedom from residues (no microplastic residues), soil compatibility, and complete degradation.
The "100 % compostable" guarantee mark labels products whose 100 % compostability has been independently tested and confirmed. It ensures that products are 100 % degraded after use without polluting the soil, environment, or the organisms living within it.
The mark is based on a binding guarantee mark statute, clearly defined test standards, independent testing procedures, and ongoing monitoring. This goes significantly beyond general environmental labeling or purely promotional statements.
The "100 % compostable" ZERKOM® guarantee mark stands for clearly tested, bindingly regulated, and traceably monitored 100 % compostability of products. It creates legal certainty, reduces greenwashing risks, and strengthens the trust of authorities, business partners, and consumers.

Technical certification seal for independent verification of recycled content in products and packaging based on the ZERKOM framework.
TECHUM – Verified Recycled Content is a technical certification seal for the independent verification of recycled content in products and packaging. The seal confirms the actual proportion of recycled material based on documented evidence, clearly defined system boundaries, and a traceable testing methodology. The goal is the factual safeguarding of quantitative recycled content claims towards the market, consumers, and supervisory bodies.
This testing procedure defines the binding requirements for the independent verification of recycled content within the framework of the TECHUM – Verified Recycled Content certification seal.
The procedure serves to substantively safeguard quantitative environmental claims and is designed to fulfill the requirements of:
The aim is to avoid misleading or unsubstantiated environmental claims and to ensure traceable, verifiable, and proportionate evidence management.
This testing procedure applies to:
Not subject to this testing procedure are:
This differentiation serves legal certainty and claim clarity in the sense of the EmpCo Directive.
The audit follows the basic principles of:
4.1 Recycled Content: Proportion of material recovered from waste and reintroduced into the production process.
Standard reference: ISO 14021:2016 – Environmental labels and declarations; EN 15343 – Plastics – Recycled Plastics – Traceability
4.2 Post-Consumer Recycled Material (PCR): Material from waste generated after use by end consumers or commercial end users.
Standard reference: ISO 14021; ISO 22095 – Chain of Custody
4.3 Pre-Consumer Recycled Material (PIR): Material from production residues that were not part of the final product and generated before use by end consumers.
Standard reference: ISO 14021
5.1 Object of certification: The percentage of recycled content of a clearly defined product or product line is certified. Overall ecological impacts or recyclability are not subject.
5.3 Auditing basis: Examination of supplier declarations, production data, and plausibility check of quantitative relations.
5.5 Validity: Certificates are limited to 12 months. Changes in material composition must be reported.
TECHUM was developed within the ZERKOM framework and follows its principles of traceability and independence. While ZERKOM acts as the regulatory framework, TECHUM takes over the specific certification application.

An independent guarantee for consumers and retail. We verify compliance with specific standards and offer legally secure quality seals.
A guarantee mark is a special type of trademark used to guarantee certain characteristics or quality features of goods or services. These marks are not used by the product manufacturer themselves, but by an independent body (ZERKOM®) that verifies and certifies compliance with certain standards. The main function of a guarantee mark is to signal to the consumer that the product or service meets certain defined criteria.
A quality seal is a visible sign (often in the form of a logo) applied to products to indicate that they meet the standards set by the guarantee mark. Only the holder of the guarantee mark has the right to award this quality seal. The holder is usually an independent organization or institution that conducts regular inspections to ensure that the products or services meet the specified requirements.
Word Mark / Fancy Mark: Serves to distinguish the goods of one company from those of other companies (origin function). Examples: "Kodak" or "Xerox".
Guarantee Mark: Confirms certain quality standards independently of the manufacturer (guarantee function). ZERKOM® uses this for guaranteed product properties.
The "100% Compostable Packaging or Products" guarantee mark would mean that all packaging or products with this quality seal are fully compostable and thus meet certain environmental standards. This mark guarantees the consumer:
Only the holder of this guarantee mark has the right to award the "100% Compostable Packaging or Products" quality seal to manufacturers whose products meet the specified criteria. This ensures that only tested and certified products may bear this seal.
Certification of 100% compostable packaging or products by ZERKOM® not only provides companies with the opportunity to build customer trust but also demonstrates their commitment to sustainability. Our guarantee marks stand for tested quality and environmental friendliness.
