The CarbonHub formula<\/h2>\n\n\n\n

What is a CarbonHub?<\/strong> It’s a cutting-edge solution for carbon transformation. Each CarbonHub is a dedicated facility where we process carbon-rich biomass, converting it into renewable energy to reduce reliance on natural gas while producing biochar<\/a> for carbon removal.<\/p>\n\n\n\n

By generating Carbon Dioxide Removal (CDR) Credits<\/a><\/strong>, our CarbonHubs actively contribute to negative emissions<\/strong>, supporting global climate goals. Every new plant we build is a CarbonHub, driving sustainable energy innovation and creating a cleaner, greener future.<\/p>\n<\/div><\/div>\n\n\n\n

The CarbonHub<\/strong><\/h2>\n\n\n\n

Ever wondered how a pyrolysis plant is constructed? Find a detailed explanation for every unit \u2013 from registration to truck loading \u2013 in this slideshow.<\/p>\n<\/div>

<\/div>
\n
\n

Unit 1: Registration and weighting<\/strong><\/h2>\n\n\n\n

Incoming trucks, either for delivery of feedstock, the pick-up of biochar, or other purposes will be registered here. This ensures safety and tracability of all vehicles entering the facility.<\/p>\n\n\n\n

The initial quality check of incoming material is also performed here.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 2: Feedstock handling<\/strong><\/h2>\n\n\n\n

Depending on the properties of the delivered feedstock, the material gets either directly stored or further processed before storage.<\/p>\n\n\n\n

Coarse material is unloaded separately and undergoes several steps of crushing and grinding to the needed properties before storage.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 3: Wet feedstock storage<\/strong><\/h2>\n\n\n\n

The feedstock from direct delivery or from pre-processing is transferred into the storage. The storage bunker is equipped with different compartments to store different qualities.<\/p>\n\n\n\n

The storage can be designed with a capacity for several days of production.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 4: Drying<\/strong><\/h2>\n\n\n\n

Before entering the pyrolysis process, the wet feedstock needs to be dried to approx. 10 % moisture content.<\/p>\n\n\n\n

From the storage it is passing a belt drying system, before entering the intermediate storage for the pyrolysis unit.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 5: Buffer tanks<\/strong><\/h2>\n\n\n\n

Each pyrolysis unit is equipped with a intermediate storage silo which acts as a buffer for several hours of production.<\/p>\n\n\n\n

This ensures the availability of the plant in case of a technical incident in the feedstock system.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 6: Pyrolysis<\/strong><\/h2>\n\n\n\n

The two pyrolysis units are the heart of the plant. Using part of the energy from the combustion process, the feedstock gets converted into biochar and syngas.<\/p>\n\n\n\n

At the outlet of the unit, the hot biochar is being cooled down and transported to further processing.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 7: Combustion chambers<\/strong><\/h2>\n\n\n\n

The extracted syngas from the pyrolysis process is burned in the combustion chamber. The hot flue gas is partly used to fuel the pyrolysis process, the main part is directed to the energy system.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 8: Energy system<\/strong><\/h2>\n\n\n\n

Using the hot flue gas from the combustion chamber outlet, steam generators use the energy to generate process steam to be used by the customer. Optionally part of the steam can be used to generate electricity.<\/p>\n\n\n\n

The exact use case depends on the steam demand and properties.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 9: Flue gas treatment<\/strong><\/h2>\n\n\n\n

The cooled down flue gas from the energy system is finally processed in the flue gas treatment system to extract dust and harmful compounds before the remains get extracted into the atmosphere with minimal environmental impact.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 10: Recycling center<\/strong><\/h2>\n\n\n\n

Central in the plant layout, the recycling center is mainly used to safely store the filtered dust from the flue gas treatment. <\/p>\n\n\n\n

It also contains facilities for any other type of material to ensure that everything is disposed of properly.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 11: Biochar post treatment<\/strong><\/h2>\n\n\n\n

The cooled biochar is either directly stored in silos or can be further treated by grinding and sieving to create different kinds of biochar products for different markets.<\/p>\n\n\n\n

For the final packaging big bags or smaller bags are possible.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 12: Biochar bulk storage<\/strong><\/h2>\n\n\n\n

The storage silos are used to store raw biochar directly from the reactor, as well as treated biochar which has been already grinded.<\/p>\n\n\n\n

A sufficient number of silos ensures the availability of different fractions of biochar.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n<\/div><\/div><\/div>\n\n\n\n
<\/div>
<\/div>
\n
\n

Unit 13: Truck loading<\/strong><\/h2>\n\n\n\n

For direct truck loading, one of the silos is equipped with a truck loading station. A bulk material truck can there be loaded directly with biochar.<\/p>\n\n\n\n

The truck-silo can also be filled with different kinds of biochar from the other silos before unloading.<\/p>\n<\/div>
