Our carbon capture solutions

Miraïa is developing solutions to leverage biomass in the most efficient manner. Producing Biochar allows us to remove carbon dioxide from the atmosphere, generate renewable energy and produce Bio-Oils. The overall process is carbon negative.

A BIT OF HISTORY

At the start of our solutions, a principle known since centuries: wood charcoal.

Wood charcoal production process is known since centuries. First treaces of wood charcoal have been discovered in archeological sites dated from Bronze Age in Europe. Our current civilization recently rediscovered the usage of biochar as soil amendment, also known as the concept of "Terra Preta".

This concept refers to black soils, highly fertile, which exist in regions of Amazonia. These soils were shaped by indigenous people, thousands of years ago by adding biochar into poor nutrient soils.

Usin Biochar as soil amendment is a sustainable method to improve soil quality, increase yield, improve water scarcity resilience and decrease greenhouse gases emissions.

OUR RAW MATERIAL

Wood: A unique and multipurposes resource

All the wood we use is local. Depending on the production cycle we will use: hardwood, softwood, pulpwood, industrial wood, wildfire wood, pruning wood, bark beetle wood and recycled wood. In all cases, we will use by-products from the wood industry coming from sustainable forests. In France, we harvest about 60% of the yearly natural growth of our forests, which allows french forest to continuously grow by 1% every year. It is detrimental to maintain that sustainable practice to avoid deforestation and maintain a renewable resource.

Miraïa's process allows to trap for thousands of years, the carbon existing within trees.

PYROLYSIS

Extracting the best elements through pyrolysis

The pyrolysis process is a thermal reaction which decomposes materials at elevated temperatures, in an environment with low or no oxygen. 

This reaction does not generate fumes nor scents as all component are used within our process. 

From this reaction we collect three outputs, Biochar, Bio-Oils, and synthetic gases. The pyrolysis reaction allows to convert woody biomass in a carbonated material: the Biochar!
Biochar
Biochar
This charcoal with a high carbon rate has multiple uses. In particular, it enables long-term CO2 sequestration as a soil improver.
Syngaz
Syngas
Syngas, standing for synthetic gases, are often referred as "poor gases". They will be leveraged to generate electricity.
Bio Huile
Bio Oil
Bio-oils are a renewable green fuel! But not only, these bio-oils will replace products that are currently derived from petrochemicals such as acetic acid, wood vinegar, Tar.
Carbon in constant motion

Carbon in constant motion

Carbon is in constant motion: trees and plants absorb carbon from the atmosphere in order to grow. This is part of the photosynthesis process. However, when the trees decompose, this carbon is released into the atmosphere. Our technology intervenes in this natural cycle to convert this CO2 into Biochar and store it for 1,000 years.

La fabrication de Biochar

Biochar production

Biochar is a plant based charcoal produced by the pyrolysis of biomass

Biochar is used as an organic soil amendment, improving soil quality and increasing crop yields, while also helping to reduce the carbon footprint by sequestering carbon within soils.

Biochar's performance in agriculture

  • Improves soil quality and retains nutrients
  • Reduces water stress (water retention capacity)
  • Lower consumption of mineral compounds and chemicals
  • Stores Nitrate
  • Reduces nitrous oxide (N02) emissions
  • Carbon sequestration

Biochar, a versatile material used in many sectors

  • Environment: ecological restoration of polluted sites
  • Construction: in the manufacture of building materials (bricks, tiles, plasterboard, cement), and asphalt.
  • Industry: catalysts for chemical reactions, activated carbons
  • Pharmaceuticals: using the absorbent properties of Biochar
Séquestration de CO2 et Carbon Dioxyde Removal

CO2 Sequestration and Carbon Dioxide Removal

Offsetting residual CO2 emissions using a process that is truly virtuous for the planet is the challenge facing all companies wishing to achieve towards carbon neutrality.

In order to limit global warming, we need to reduce and stop our greenhouse gas emissions on a global scale. In addition to that we also need to capture and store CO2 on a permanent basis. Out of all the technologies and processes to capture carbon, Biochar offers many advantages! Our Carbon Dioxide Removal certificates are verified and audited by recognized verification firms that are neutral and use facts and science based methods.
Produire des énergies renouvelables

Producing renewable energy

Our continuous pyrolysis technology enables us to produce renewable energy, at the heart of the region we are implemented, without intermittence.

Depending on the needs, our plants will produce heat and/or electricity.

La chimie verte : un intérêt croissant

Growing interest in green chemistry

The heavy dependence of our societies on the petrochemical industry since the 1950s has led us to neglect the advantages and virtues of wood.

Our Bio Oil extracted from pyrolysis could be used as low carbon fuel that replaces petroleum fuel oil. Other by-products, such as acetic acid and wood vinegar, are also of interest for many industries. These biosourced products are ways to support decarbonization and create added value in our regions.

Benefits of Green Wood Chemistry

  • Using a renewable resource: wood
  • Supporting National energy sovereignty
  • Creating high value-added products

Green Chemistry products extracted from wood

  • Biofuels
