Certification of biogas plants and products

 

Not all forms of biogas are the same. naturemade star-certified biogas is characterised by a particularly small ecological footprint, all the way from the delivery of substrate through to the gas being fed into the distribution network – regardless of whether certified biogas is produced in Switzerland or abroad.

naturemade star biogas is only produced from organic residue such as organic waste, green waste, manure and sewage sludge. No energy crops are used. The certification process also includes a review of additional criteria, including high standards of production plants in terms of methane leakage, noise and odour, the exclusion of genetically modified organisms and the licensee’s demonstrably sustainable corporate policies.

Benefits of naturemade star certification

The naturemade quality label creates a strong foundation for marketing the added renewable and environmental value of biogas. Because energy needs quality!

As a producer, naturemade certification provides you with credible, audited evidence of climate-friendly, green energy production.

As a supplier, certification enables you to provide your customers with 100% guaranteed renewable, green energy – sponsored by a Swiss quality label that enjoys the broad support of environmental and consumer organisations and the energy industry.

As an end customer, certification gives you certainty that your biogas is not only renewable but has also been produced through particularly environmentally friendly processes. The separate certification of biogas production and supplies ensures that only as much naturemade star biogas is sold as has been produced.

 

Certification process for biogas plants

Do the “Quick compliance check with key criteria for biogas plants” (see the flyout menu below).

 

 

Please contact the VUE executive office for an initial consultation.

 

Select a VUE-accredited lead auditor from the list provided and organise a time for your audit with your auditor. The audit will examine whether the naturemade certification criteria are complied with.

 

 

Complete the following application forms and the required declaration in preparation for the audit (you can do this yourself or together with your auditor) and collate the necessary documentation:

The lead auditor will submit all documents including the audit report to the VUE executive office. Please note the submission dates (four dates per year; noted in the margin column on the right). Alternatively you may apply for express certification by paying a CHF1,000 surcharge.

 

 

The VUE Board examines the applications for certification it receives and decides whether certification is warranted.

 

The lead auditor carries out annual review audits, which involve checks of the energy accounts, a review of existing requirements and a brief check of compliance with criteria (see the document “Review audit preparation for licensees of energy generation plants” (only available in German and French)).

 

 

naturemade licenses are valid for a term of 5 years. After this term, licenses may be renewed following a recertification audit.

 

Certification process for biogas products

In contrast to the certification of biogas plants, there is no need to undergo an initial certification audit when applying for biogas product certification.

 

Please contact the VUE executive office for an initial consultation.

 

Complete the following documents to apply for a license for your biogas product.

Please submit the completed documents to the VUE executive office. Please note the submission dates (four dates per year; noted in the margin column on the right).

 

 

The VUE Board examines the applications for certification it receives and decides whether certification is warranted.

 

Annual review audits must be carried out by a VUE-accredited lead auditor. Review audits involve checks of the energy accounts, a review of existing requirements and a brief check of compliance with criteria (see the document “Review audit preparation for licensees of energy supplies” (only available in German and French)).

 

 

Recertification is carried out every five years.

Additional costs may be incurred when action needs to be taken to comply with the naturemade criteria.

 

What plants or biogas products are currently certified?

 

What impacts does biogas production have on the national greenhouse gas balance?

While biogas production is continually expanded in Switzerland, domestic demand is currently more than twice as high as supply, and additional biogas is therefore imported via the European gas grid. For imported biogas, naturemade ensures that its tradeable added value is not marketed twice and is instead fully transferred to the biogas customer. As a result, customers buying naturemade star biogas make an important contribution to reducing global CO2 emissions.

Based on current legislation, Swiss biogas customers only impact on the national Swiss climate balance if biogas is produced domestically. According to the territorial principle of the International Climate Convention, the emissions avoided by biogas production are credited to the greenhouse gas balance of the country where the biogas was produced. However, customers buying naturemade star biogas always make an important personal contribution to global climate protection, regardless of where the biogas was generated.

For further information please refer to our factsheet on the origin of naturemade star biogas (only available in German and French).
