09/05/2012 (Biofuels Digest) - In Europe, biodiesel plants are turning to animal fats and waste oils in an attempt to stay viable in a market where poor canola crop forecasts mean canola prices have skyrocketed, eating into biodiesel margins. Margins have halved this season from $100 per metric ton last year. Canola oil use for biodiesel has fallen by 800,000 tonnes, replaced by waste cooking oil and animal fats, as well as a major boost in palm oil imports.
