Abstract
85 000 m3 of Ulva sp. is harvested each year in Brittany (France) during a 3–4-month season. Spreading is often impossible and the alga does not keep for more than a few days. Storage results in objectionable odours and release of a liquified fraction. Such pollution can be suppressed by composting the alga with the lowest possible quantity of ligno-cellulosic substrates. This results in the stabilisation of the seaweed, and its use can thereby be delayed. This system of processing the seaweed decreases the cost of treatment by composting and the product can be used either as a substrate for later composting or as an organic enhancing and fertilising agent.
