Can you manufacture biogas from landfill waste?

Biogas production is a very promising technique to handle the waste treatment problem due to the amount of waste generated. In addition, the solid residues from fermentation could be used as fertilizers.

Composition of Biogas

When microorganisms decompose organic waste, landfill gases or biogases are created. Almost, 90 to 98 % of landfill gas is methane (CH₄) and carbon dioxide (CO₂). Nitrogen, oxygen, ammonia, sulphides, hydrogen, and other gases make up the remaining 2 to 10%.

Because all MSW or Municipal Solid Waste landfills are required by law to treat both types of wastes, i.e., leachate and biogas, we'll look at how biogas can be collected and re-used as an energy source for the treatment of leachates without incurring the high expenses associated with converting biogas to energy or fuel for other purposes.

Is it profitable to recover biogas energy?

Recovering energy from waste-biogas transformation can be economical since the biogas produced by landfills can be used for two purposes:

1: For the purpose of creating both thermal and electric energy; Motor-generator units or biogas turbines can be used to carry out this procedure;

2: For the purpose of fuel usage after purification, providing fuel for biogas boilers, injection into the natural gas distribution systems and fuel for automobiles.

Problems faced in the biogas generation on-site

The installation of the apparatus required for the conversion of biogas into electricity or fuel is too expensive and, more importantly, unprofitable for most MSW landfills. This is due to the fact that the amount of biogas produced in most landfills is insufficient to create a significant amount of energy that can be used to offset the machinery investment.

On the other hand, even when landfills are capable of creating substantial amounts of electrical energy, there are rarely any adjacent electricity transmission towers to which the created energy may be transported.

Biogas can be a source of energy for leachate treatment in smaller landfills_

For landfills that do not produce a big volume of biogas, repurposing it as a source of energy to power landfill processes is a better option.

There are a variety of technologies that can be used to treat MSW landfill leachates, but vacuum evaporation, in combination with or without pre- or post-reverse osmosis, has proven to be the most effective approach for reducing leachate and obtaining purified water appropriate for release.

Conclusion

The vacuum evaporator's energy needs might be met by biogas from the landfill. The implementation of a basic and cost-effective technology, such as a boiler with a methane burner, will allow sufficient energy to be obtained to assure the evaporator's proper operation. It provides the following advantages:

1: It is possible to reuse it as an energy source;

2: The energy required to run the vacuum evaporator, which is used to treat the leachate will be free;

3: In the event of landfills that do not yield enough biogas to warrant the massive expenditure required to convert it into electricity, thermal energy, or fuel, biogas can be reused in a far more profitable way.
