The SeaCH4NGE project investigated whether Icelandic algae can reduce methane emissions from cows. But foreign studies have shown that the use of algae as part of feed can reduce the production of methane gas from ruminants.

A wide range of Icelandic algae was studied and whether they can reduce methane from cows.

The algae were studied both in laboratories for chemical content and also for their ability to reduce methane production. The algae that came out best in laboratories will then be further investigated in a feed experiment with cows.

Below is a video in English which is a short summary of the project and its benefits.
