Preface The cultivation of microalgae can playan important role in environmentalfriendly production of raw materials for biodiesel. In addition, algae offer several other useful materials for the food and chemical industry. This booklet describes the possibilities for economically viable large scale algae cultivation for the production of valuable products, including raw material for biodiesel. Chapter 1 illustrates the potential role ofmicroalgae in developing a more sustainable society. Chapter 2 describes some important groups of algae and the opportunities they offer as producers of useful substances. Chapter 3 deals with the main algae cultivation systems and the current state-of-the-art of algae cultivation in the Netherlands. Chapter 4 discusses the benefits of algae cultivation in relation to other agricultural crops. Chapter5 analyses the possibilities of cost-effective, large-scale microalgal production and the significant role that the new algae centre in Wageningen, AlgaePARC, will play in the research on optimization of algae cultivation. Chapter 6 is a summary of the conclusions and recommendations for costeffective microalgae cultivation.
