• Meat meal and industrial fat as alternative fuels in agriculture

  I study new energy sources which can replace fossil fuels. As I deal with the burning processes, I have analyzed several kinds of wastes. I think one solution for replacing fossil fuels would be to burn regenerated energy sources in agriculture. For example, oil, industrial fat and meat meal from processing plants are treated as hazardous wastes. There exist non-hazardous wastes for energy recovery, as by-products e.g. sawdust, wood shavings, vegetable oils, stems of plants or poultry manure.
  We should produce energy from the outsides of vegetables and juices, and should produce bioethanol by fermenting vegetable wastes. We could treat the used vegetable oil to make bio-diesel fuel. Meat meal and fat are good alternative energy forms, if burnt in incineration plants. These materials are new renewable sources of energy.
  There are some problems in the use of biomass for energy sources. We have to look for the best loading device and burning processes.

  Fuelwood, and wood wastes provide almost half of the renewable energy production of the European Union. Enhancing the use of wood in renewable energy production has more constraint than wind- or solar energy. Forests in the EU member states are sustainably used, they are increasing both in terms of area, and growing stocks. There are possibilities to enhance the fallings and use more fuelwood. Short rotation coppices could fulfill the long term demand for fuelwood; because these plantations surpass the dendromass yield of forests.
