Energy Recovery From Various Wastes

Energy recovery from the wastes is the process of generating energy from the various waste materials which are ready for the disposal unit.  The energy is either electricity, heat, or fuel that can be used in homes or commercial places.

In other terms, Energy Recovery is the process of converting non-recyclable waste materials into useful energy through processor combustion, gasification, landfill gas recovery, anaerobic digestion, and pyrolization. This is also known as waste- energy cycle.

Energy recovery is the key part of the waste management process, helps to convert solid wastes and hazardous wastes into useful energy. This process involves various waste management strategies and it helps to minimize the wastes in the disposal units.  The burning or combustion process is the one among the effective process in waste -energy cycle, here not only the volume of wastes reduced but also the wastes are recovered as energy after the combustion process. The energy recovery process has lots of benefits like it limits carbon emission by generating renewable energy sources and it also reduces the emission of methane gas from landfills.  This process also helps to prevent the atmosphere from the various pollution, reduces greenhouse gases, and makes the environment healthy and green.

How to recover energy from wastes

What are the advantages of Energy Recovery?

The energy recovery setup process may require an initial amount but this the one-time investment that helps you to reduce wastes and improve your environment.

  1. Reduces the quantity of waste material from residential and commercial places
  2. Helps to maintain an efficient waste management process
  3. Generation of heat and power
  4. Helps to reduce the pollution in the environment
  5. Saves transportation cost spends of collecting the wastes from home to the disposal unit
  6. Prevent the emission of unpleasant odor
  7. Helps to prevent the emission of methane gas
  8. Also helps to keep away the various gems and diseases
  9.  This process is not dependent on any weather, works on all weathers
  10. Requires only a small area.

Top 3 Energy Recovering Process

1.  Combustion

Combustion is the process of burning the waste materials in the enclosed area and treating the disposing of solid and hazardous wastes. The combustion process involves two separate categories one for solid hazardous wastes and another one is for liquid hazardous wastes. The two categories of the combustion process are named as

  • Incinerators – This the combustion process used only to recover the energy.
  • Boilers and Industrial Furnaces – This process is used to convert energy and material recovery.

Landfill Gas recovery

2. Gasification

Gasification is the process of creating energy from the wastes. Here the carbonaceous materials are converted into carbon dioxide and carbon mono oxide and also produce little hydrogen gas in the presence of oxygen at the high temperature. In the process of Gasification, synthesis gas is generated from hazardous wastes and it can be used to produce heat or electricity.

3. Landfill gas recovery

Landfill gas recovery (LPG)  is the process of collecting methane gas from the wastes deposited in landfills. LPG is the product that arrives from the decomposition of organic substances in landfills. The LPG is the combination of an equal amount of methane and carbon dioxide and a small number of organic compounds.

Tips For Converting Waste Into Energy

Wastes are generated in an abundant manner from domestic areas, industrial areas, organizational areas, etc. The waste material may contain both decomposable and non-decomposable materials in it. The special care must be taken to segregate the wastes and to dispose of them safely in an eco-friendly manner. The decomposable materials can be processed and converted into energy.

waste to energy

Waste treatment is the process of generating electricity or heat energy from the decomposable waste materials. The waste materials are collected in the large amount from the domestic and industrial areas, They are then dumped into large pits. Later these wastes are burned to produce the heat energy. Thus, in this case, the waste is converted into thermal energy. Now, this thermal energy is converted into the electric energy by turning the turbine on.

Another energy source from the garbage wastes is methane gas. The methane gas is produced from the waste decays which can be used as a fuel. The Kitchen wastes can be utilized well to generate energy.

Steps to convert kitchen waste into energy:

waste energyInitially, the wastes are separated into dry wastes and wet wastes. These wastes are stored in separate trash cans. Once the cans are full the wastes are dumped into composts. The compost is also filled with dry leaves. The semi-composted materials like buttermilk, cow dung, etc are added to start the decomposition process. The pile is turned around daily to make sure that it is maintained at the right level of dampness. If the pile is too wet then the dry leaves are added. If the pile is too dry then water is added. The compost is left as like for more than a month to decompose. After two months the compost will turn out into a manure which can be used in agricultural fields.

waste energyThe bio-degradable wastes can be converted into energy or manure. Whereas the non bio-degradable wastes must be taken care to dispose of safely in an eco-friendly manner. The non decomposable wastes like plastics, rubber tires, etc are sent to the recycling plant for reuse. Other waste materials like metal scraps, glasses are also treated in the same way. Throwing of the wastes into the agricultural lands must be avoided in order to preserve the environment. Burning of plastic wastes and rubber tires will produce toxic gases which are injurious to human health and hazardous to the environment as well. The waste clearance companies will involve in recovering the solid wastes and disposing of them in a safe eco-friendly manner.
