Climate changes together with the increased scarcity of raw material and natural resources place pressure on politicians, industry and society to optimize energy utilization and material recovery. The recycling and sorting of the solid waste and the need for long and short term storage is therefore steadily increasing as is the development of different types of storageand transportation of biofuels. Many of these stores are or will be located close to settlements, town districts and buildings of high monetary value which will increase the potential risk with associated fires and their effect on public health. Methods for the handling and storing organic materials are many, but whether after a short or long time, these all have a propensity to end up with self ignition. Sweden has increased the number of incinerators for solid waste by almost 40 % during the new millennium. Further, numerous upgrades of old incinerators have been carried out and a large volume of storage of waste fuels is needed. This paper presents experience from storage of waste fuels, risks of fire, and issues associated with fire fighting, emissions, and financial impact. Discussions of future trends for the storage of organic material, waste and biofuels as well as the risk of energy and material loss and environmental pollution by smoke and danger for health are included as well as the need for further knowledge and research.
