Fossil fuels are not in endless supply. Fact. Waste disposal is a global environmental problem. Fact. energy from waste , as an alternative to fossil fuels, provides an important contribution towards the reduction in landfill disposal and global warming.
Energy recovery from waste provides a double environmental benefit - firstly, the diversion of waste from landfill and, secondly, the recovery of energy, displacing fossil fuel alternatives and reducing greenhouse gas emissions.
Turning municipal solid waste to electricity has a large number of benefits. This energy source is domestic, and is produced close to home. There are no worries about unstable regimes or sudden price spikes because of politics. Best of all, the energy is created using waste, something that is discarded because it is no longer useful. There is no shortage of municipal solid waste, and waste management methods that use waste to energy processes can help supply much needed energy. Municipal solid waste can be turned into electricity to power and light your home, allowing it to make a full circle from your home as garbage and back to your home as electricity.
Food waste is another important resource for energy. The bioconversion of food waste for energy production can result in biofuels, like ethanol and biodiesel, as well as other types of energy. These biofuels burn much cleaner than traditional fossil fuels, and do not cause as much harm to the environment. They are generally considered just as efficient, and boats and cars have used these biofuels against vehicles using fossil fuels during races and won, showing that there are no performance differences.
Alternative methods of recycling municipal waste can include pyrolysis and gasification. There are a few small differences between these two processes, mainly the amount of oxygen that is included in the process. Both of these methods can create energy from waste, in the form of both heat and gases that can be used for energy or sold for a profit. Managing municipal waste is important, because many landfills are full and others are nearing their capacity. Just dumping our trash in a landfill, even one designed for safety and maximum effectiveness, is no longer an option. Using this waste as an energy source is a good idea all the way around, and everyone benefits.
