Abstract
The object of this study is to compile the existing knowledge of sewage sludge, ash, leachate from landfill and municipal water and their problems and possibilities as fertilizers of energy crops. The interest lies in the possibility of linking these waste products with the cultivation of energy crops and in obtaining a recycling system. The purpose is to achieve less environmental load and less costs both for society and farmers. It is also of great concern that the long-term productivity of the soils is preserved so that, when necessary, we can quit growing energy crops and start producing grain without any danger. The dislike of using sewage sludge, ash, leachate from landfill and municipal wastewater as fertilizers depends on their contents of heavy metals and the organic pollution of the environment. The knowledge of the content of heavy metals in the various waste products, the mobility of heavy metals in the ground, the absorption by plants and toxicity is comparatively good. However, there are considerably more question marks concerning organic environmental pollution. There is uncertainty regarding organic pollution in the waste products, the effect on ground biology, bioaccumulation, toxicity. In the light of these facts, increased knowledge of organic pollution,

In the light of these facts, increased knowledge of organic pollution, closer study of pre-purification of ash, study and development of different combinations of sewage sludge, ash, leachate from landfill and municipal water in a soil-plant system and also a better model of the economy of recycling are considered to be particularly interesting in continuing the development in this field.
