Recovery energy Essay
...Start of the Recovery energy Essay...
Recovery energy or fatal energy is the amount of energy that is inevitably present or trapped in certain processes or products, which can sometimes be partially recovered or used. This energy can take different forms (heat, cold, gas, electricity) and is emitted by industrial processes, public service companies or waste in particular. This term also refers to the energy that would be lost if it were not used when it is available. This is the case, for example, with electricity from wind turbines, solar panels or run-of-river hydropower plants. Fatal energy can be contained in materials or processes.

The methanization of organic waste can produce substantial quantities of methane. Reuse or recycling techniques, further upstream are other means, often even more efficient, to recover or use the fatal energy of objects at the end of their life for a longer time. Generating electricity, heating food, a house, sanitary water, among others, disperses calories, most of which will be lost without being useful. This type of waste can be reduced. In Quebec, the Energy Efficiency Fund is subsidizing the purchase of heat recovery systems for shower water to reduce the cost of heating (financial assistance of $ 400 to the 'purchase).

Apart from household waste incineration plants (UIOM), in industry too, there is a lot of fatal heat. The iron and steel, chemical, cement, agro-food, computer server farms and glass sectors thus produce a large amount of heat which is often lost in the atmosphere. In Europe in order to stem this waste, European Directive 2012/27 / EU on energy efficiency makes a cost-benefit analysis compulsory for the recovery of waste heat through a district heating network project. In France, the industrial waste heat source was estimated by ADEME in 2017 at 109.5 TWh, or 36% of fuel consumption. Household Waste Incineration Units (UIOM), Pumping Energy Transfer Stations (STEP) and data centers have a fatal heat deposit estimated at 8.4 TWh.

(source www.unpluggedliving.com) Another option is to mix the recyclables with the general waste stream for collection and then sorting and recovery of the recyclable materials can be performed by the municipality at a suitable site.Some sanitary landfills are used to recover energy.These enhanced microbial processes have the advantage of rapidly reducing the volume of the waste creating more space for additional waste, they also maximise the production and capture of methane for energy recovery systems and they reduce the costs associated with leachate management.This method may be used as a means of recovering energy to be used in heating or the supply of electricity.In addition to supplying energy incineration technologies have the ad...

The Directive also requires Member States to take appropriate measures to encourage firstly, the prevention or reduction of waste production and its harmfulness and secondly the recovery of waste by means of recycling, re-use or reclamation or any other process with a view to extracting secondary raw materials, or the use of waste as a source of energy” (Department for Environment, Food and Rural Affairs, 2009).Biomass (waste) energy is increasingly attracting attention worldwide because it is a renewable source of energy and potentially CO2 neutral.According to the World Energy Council, fossil fuel covers about 82% of the world’s energy.Research and development of renewable sources of energy and energy from biomass is expected to be of ...

There are also some very new and developing technologies that produce energy from waste and other fuels without direct combustion like that of incinerators.A modern form of waste management is Plasma arc gasification it uses a very high electrical energy and the extreme temperatures created by an electrical arc gasifies.Recycling can also be a way to gather energy through thermal treatment from using waste as a way to use for appliances, and too make boilers to produce steam and electricity in a turbine.Another method of making waste or other products into energy is gasification which converts carbon materials like coal and petroleum into carbon monoxide and hydrogen by placing the materials in a high temperature within a controlled sett...
