Biochar Production Solution for CDR Integration

If your goal is to manufacture premium-grade biochar with high fixed carbon, low ash content, and homogeneous particle quality, an advanced continuous pyrolysis system is the best solution. During continuous pyrolysis, biomass is heated under precisely controlled temperatures and residence times, ensuring uniform carbonization. This results in biochar with stable structure, reduced impurities, and strong performance for soil improvement. A complete line includes feeding, pyrolysis reactor, cooling, discharging, and emissions treatment. Such systems are ideal for EU agricultural markets, organic farming, horticulture, and CDR-eligible production because they deliver consistent, certifiable quality.

When you want to convert loose biochar powder into higher-value products, the granulation process is essential. Granulation forms the biochar into round pellets with excellent strength, uniformity, and easy application in agricultural equipment. Under rotational or extrusion force, the processed biochar material forms dense and durable granules with improved flowability and storage stability. This type of premium pellet is preferred for greenhouse agriculture, vineyards, berry crops, and high-value soil improvers. For the granulation step, disc pelletizers or rotary drum granulators are common options depending on moisture, formulation, and capacity requirements.

If you focus on maximizing product performance and market value, creating biochar-based fertilizer blends is an excellent choice. These formulations combine biochar with compost, minerals (Ca, Mg, Si), or organic additives to enhance nutrient retention, microbial activity, and soil structure. The blended material is processed through mixing and optional granulation to create premium fertilizers tailored for berries, vineyards, vegetables, and greenhouse crops. Because biochar acts as a long-term carbon sink, these products can also qualify for CDR certification under standards such as EBC-CDR and Puro.Earth. This integrated approach offers dual revenue streams: fertilizer sales and carbon credit generation from 1 ton of biochar equaling 2.0–2.4 tons of CO₂ removed.

Wet granulation is ideal for producers who want round, uniform, and high-density biochar pellets. A 1-6 t/h disc pelletizer allows flexible moisture adjustment and precise control over particle size, making it suitable for medium-scale premium pellet production. For larger capacities, the 1–30 t/h rotary drum granulator provides continuous, stable granulation with strong shaping force and high efficiency. Both machines rely on binder-assisted pellet formation, offering smooth surfaces, excellent flowability, and strong mechanical strength for agricultural application equipment.

Dry granulation works best when moisture levels must stay low or when producers prefer harder, compression-formed pellets. The double roller press granulator compresses biochar powder into uniform granules without adding water or binders, achieving high density and minimal drying requirements. For small to medium outputs, the 1–2.5 t/h flat die pellet mill forms cylindrical pellets with strong durability and stable structure. This method reduces energy use, simplifies production, and creates pellets suitable for blending into mineral-enhanced or compost-based biochar fertilizers.

To produce high-quality biochar fertilizer, you must first crush charcoal blocks, biochar chips, and compost clumps into fine powder. Finer particle size improves the nutrient absorption of powdery fertilizers and enhances pellet formation for granular products. A vertical fertilizer crusher is suitable for handling both biochar and compost, ensuring uniform particle size and preparing materials for efficient mixing and granulation.

Next, to achieve consistent nutrient distribution in the final fertilizer, the mixed materials must be blended thoroughly. A fertilizer mixer ensures even combination of biochar powder with compost. Depending on your capacity and efficiency needs, you can choose from several mixers, including large-scale horizontal mixers, high-speed double-shaft blenders, or low-cost disc mixers. These systems ensure uniformity and stability for both small-scale and industrial productions.

If you want to improve storage stability, transport efficiency, and controlled-release performance, granulating the biochar–compost mixture is a highly effective step. You can choose a pan pelletizer for small-scale biochar fertilizer production, a rotary drum granulator for large-scale carbon-based fertilizer manufacturing, or a double roller granulator for low-cost dry granulation without adding water. Each machine helps you produce strong, uniform organic fertilizer granules with higher commercial value.
