This document specifies methods for the measurement of energy content and main elements balances of algae from cultivation or from wild growth and algae products to provide biomass, intended for renewable algal raw material used as bioenergy and in bio-based products. This document also specifies carbon source parameters specific to algae as bio-based and it is applicable to studies covering algae production life cycle assessment (LCA) e.g. algal biomass farming or wild collection. This document does not apply to methods of algae and algae products sampling, harvesting and pre/postprocessing. This document does not apply to algae and algae products intended for the food and feed sector.
