1)Thorverks products are annually certified by respected international auditing agencies:
Quality Assurance International (QAI) audits our production and operations. The certification is issued annually after inspection. As examples we attach 2017 Certificate for organic production. Certification. A certification is added annually.
After passing a thorough inspection annually Thorverk is allowed to use the certified label USDA for products that are imported to the US according to an annual audit of our performance.
The QAI audits and certifications allow us to use the label from the United States Department of Agriculture as certifying a pure and natural organic product.
OTCO audits our wild harvest.
Their annual audits certify the full traceability of our products from harvesting sites to delivered bags of algal-meal from Thorverk's production plant. OTCO certification means that our methods and schemes for sustainable harvest are recognised and that we follow them through.
European leaf and Icelandic audit.
The Icelandic auditor "Vottunarstofan Tún" is an independent inspection- and certification body. The agency audits for organic and sustainable production, operation and resource harvesting. Their audits are carried out annuallly and the certificates issued accordingly.
2) Ingredients and analysis
Thorverk´s products are 100% organic and natural. The raw material is only dried and milled. During the production process nothing is added and nothing is removed except for steamed water. The contents of the meal can and will vary due to seasonal variations. The ingredients reflect natural conditions in the wild growth patches. Thorverk does not have all batch of harvest. chemically analysed. Asco can be used to mix into animal feed in small amounts. Asco and Lam are not fit for human consumption untreated.
Sometimes customers are not familiar with the terms used in standard international units. Here is an example of the meaning of ppm. Lets say hypothetically for the amount of iodine in seaweed:
NotaBene! most tablet producers pre-treat the seaweed and use several species in their mixtures. Therefore read final product labels for more accurate amounts. Our milled seaweed usually has humidity 7-9%. Often the standard for analysins is set for 12% humidity
| Type of unwashed Seaweed | Indicator | amount | amount | one tablet (eq 0,56g) | or ppm |
| Units | mg/kg | mg/100g | mg/1g | mg/1 tablet | |
| Laminaria d | 862 | 8,6 | 0,86 | 0,43 | 862 |
| Ascophyllum | 4700 | 47 | 4,7 | 2,6 | 4700 |
| (1kg=1000g=1.000.000mg) |
Things that affect the composition of the end-products are intensity of sunlight, temperature and other weather factors, seasons, and wave action, drift ice and age of seaweed. Because of these natural fluctuations we cannot issue a Standard Certificate of Analysis for each batch and we do not analyse every batch. We provide instead a Typical Analysis as shown below.
Typical analysis for Ascophyllum nodosum
Typical analysis for Laminaria digitata
Upon request Thorverk can have single batches of meal analysed by an independent body but this must be paid by the interested purchaser. Meal of Asco and Laminaria are not meant for human consumtion. It needs pretreament or blending with other species as not to override the maximum allowed contents of Cd and As.
Also, please note definitions in Thorverk´s Standard Terms and Conditions.
