Gas Stabilizer, the “brain” that recovers biogas (+32%)

Biogas is a very precious renewable source which in Italy alone is worth around 2 billion cubic meters per year. Making biogas extraction more efficient is at the center of the work of the startup Zero3 which operates in the renewable energy sector, founded in 2018 by Marco Antonini and Francesca Sandrini, both engineers with twenty years of experience. Zero3’s mission is to design, build, supply and manage systems for the energy recovery of biogas and for efficiency in the production of green energy. To achieve these objectives, Zero3 has developed advanced technological solutions, awarded internationally, such as Gas Stabilizer, an automatic regulation system for optimizing biogas capture.

Gas Stabilizer, a new brain for biogas extraction

One of the main technologies designed by Zero3 is the Gas Stabilizer, a patented system for the capture of biogas that reduces the dispersion of methane from landfills thanks to the automation for the management and continuous and remote control of the gas capture. Gas Stabilizer reduces environmental pollution and improves the quantity and quality of the fuel obtained from waste, which can be used for the production of electricity or biomethane.

Gas Stabilizer is the first landfill biogas collection automation system that acts as the “brain” of the entire collection system present in the landfill: it acts automatically, 24 hours a day, real time and with the possibility of interaction, control, regulation, monitoring and verification even remotely.

It is modular and separable and can be applied to any type of biogas collector system or regulation station, both new and already existing in the landfill plant. A scalable, modular and universal solution, suitable for any type of system, which consumes only 150W.

The advantages of Gas Stabilizer

The innovative integration into biogas collection systems optimizes their performance and efficiency.
The main advantages of Gas Stabilizer range from energy recovery to pollution reduction, up to the simplicity of installation.

• Energy recovery: automatic regulation that optimizes the quality and quantity of biogas
• Elimination of odors coming from the landfill or production site
• Reduction of environmental pollution of methane (CH4) emissions
• Automation of the regulation of the collection parameters
• Prevention of fire/explosion risk
• Greater security thanks to real time and remote monitoring
• Adaptability to any type of collector system, new or existing
• Easy installation, simple management, maintenance and adjustment
• Increase in economic income thanks to the increase in energy production and the improvement of collection performance

Traditional collection systems are still managed manually by landfill operators with weekly adjustment frequencies. The Gas Stabilizer, however, acts automatically on the regulation of each collection well, as well as acting on the control of the parameters that characterize the mixture of biogas captured (methane, oxygen, carbon dioxide, etc…).

The strengths of Gas Stabilizer make this solution particularly interesting in a global scenario in which over 60% of waste is disposed of in landfills and urban waste landfills are large producers of biogas given that normally 30 to 50% of waste is composed of organic material.

Gas Stabilizer allows:

• Data storage and analysis to optimize energy potential
• Line monitoring and targeted maintenance
• Average increase from 5% to 30% vol of biogas captured, improving energy gains
• Remote control and adjustment
• Each standard module consumes only 150 watts.

Gas Stabilizer numbers: + 32% of biogas recovered

Gas Stabilizer allows you to reduce the environmental impact of biogas production: less dispersion, more clean energy.

• 31.98% is the overall average increase in volumes of biogas (landfill gas) captured compared to traditional capture systems usually installed in landfills
• Reduction of the Carbon Footprint of over 7,800 Tons * – a unit of measurement that allows different greenhouse gas emissions with different climate-altering effects to be weighed together – in terms of CO2eq every year, only with an increase of 20% in volume of biogas captured and sent for energy recovery, for each 1 MW electricity production plant

Why is landfill biogas important?

Landfill biogas contains methane, as it is produced during the natural degradation of the organic fraction present in the waste and the biogasification phenomenon, once started, lasts for at least 30 years. This means that waste disposed of today will produce biogas until 2054.

The emission of methane into the atmosphere represents a significant contribution to climate change phenomena by virtue of the significant global warming potential that characterizes it and which corresponds to:

• 27.9 times that of carbon dioxide over a 100-year time horizon
• 81.2 times that of carbon dioxide over a 20-year time horizon

This means that the methane emitted into the atmosphere, especially in the short period of the first 20 years, causes significant damage to the climate and the environment. But landfill biogas is a combustible mixture that can be used to produce energy in a thermodynamically convenient way and is a renewable energy resource that can contribute to achieving the objectives of the Energy Transition.

The international state of the art of the most advanced countries identifies an average efficiency of capture of the biogas produced by landfills of around 50%. This means that in the world, authorized and controlled landfills, equipped with technological biogas capture systems, manage to capture around 50% of the renewable biogas resource they produce, the rest goes into free emission. And let’s not forget that in the world there are also unauthorized landfills, for which there is no data evidence.

Zero 3 at SIOS24 Summer

Are you curious to learn more about this revolutionary technology capable of recovering all the biogas produced from waste disposed of in landfill? Do you want to understand how it is possible to eliminate polluting emissions and unpleasant odors emitted into the atmosphere? Are you interested in discovering this new technology that restores intelligence to the entire collection system present in the landfill?

The Zero3 team will be present at the Innovation Village of SIOS24 Summer Roma, at the Gazometro on June 20th. The opportunity to network, discover the technology for biogas capture with all the specific technical details and generate collaboration opportunities.
