Maximize Your Power Plant's Efficiency

Methane gas is produced when organic waste decomposes in an oxygen-free environment, such as deep within a landfill. This methane can be trapped and used to generate electricity, instead of being released into the atmosphere.

Wastewater treatment systems begin by collecting solid sludge. In a sludge-to-energy system, this sludge is subsequently processed with thermal hydrolysis to maximise the amount of methane it can produce. The processed waste is then fed into an anaerobic digester, which thoroughly digests it.

The end result is a methane-rich gas, or biogas, which can be utilized for on-site energy demands, or further processed and used in place of natural gas. Furthermore, the solid waste remnants produce a nutrient-rich "digestate" that can be put to soil, to enhance plant development.

Other organic wastes, such as yard waste, manure, leftover food scraps, and restaurant waste oil, are excellent options for waste-to-energy systems. These wastes can also be combined to boost methane production. Blending sludge with kitchen waste, for example, produces the optimum blend of organic materials, and necessary microbes for efficient methane production. 

Sludge-to-energy systems address many of the world's most pressing environmental and economic issues, at the same time. This is just a short list:

The globe requires more energy to support rising cities and growing people. For many communities, using waste for energy is a low-cost, renewable, and easily available source of energy.

Sewage treatment plants can be energy self-sufficient because they can use biogas, generated from their own sludge to power their operations. This ensures that a sewage plant's principal job of eliminating pollutants and disease-causing microorganisms, is not disrupted by power outages in the surrounding area.

Methane accounts for 16% of worldwide greenhouse gas emissions and is a powerful greenhouse gas, about 30 times more powerful than carbon dioxide. Sludge-to-energy systems use methane for energy instead of releasing it into the atmosphere, where it contributes to climate change.

Although, methane emits carbon dioxide when utilized to generate energy, the net emissions are low when methane-rich biogas is used instead of fossil fuels.

Many developing countries lack the infrastructure required to manage solid waste and sludge effectively. This poisonous, foul-smelling waste is frequently thrown straight onto land or neighbouring seas in these places, endangering public health.

Over 70% of municipal solid waste and sludge in India, for example, is landfilled or dumped—sometimes illegally. A sludge-to-energy strategy offers a solution.

Sludge-to-energy systems eliminate the need for more expensive and polluting forms of energy, such as fossil fuels. Furthermore, those who run waste-to-energy plants can profit financially, from the sale of gas and solid digestate.
