In the report fire risks with handling and storage of different types of biofuels or waste are discussed. The report gives an overview of different types of biofuels, future trends, different ways of storage, experiences from occurred fires, and previous or ongoing research project within the field. The EC Directive on landfill of waste together with the need and interest for biofuels have resulted in increased amounts and a new type of storages. This also means new types of risks. There is therefore a great need for knowledge on the risks for spontaneous ignition and fire characteristics for these fuels and storages. If a fire occurs it can lead to significant problems with emissions and in many cases the rescue services have problems with handling these fires. The fires can also lead to large economic losses. It is, therefore, important to know both how to avoid and how to facilitate extinguishment of these fires. The information gathered and presented in the report has been used to develop a proposal for a research programme, which is also presented in the report. The report deals mainly with solid biofuels and waste, but discussions on liquids and gaseous fuels are also included.
