Biochar can sequester carbon in the soil for hundreds of years. Investors can earn Carbon Dioxide Removal (CDR) credits to trade.
Biochar improves soil structure, enhancing aeration, water retention, and nutrient-holding capacity; it also adsorbs harmful substances, promotes microbial activity, and ameliorates acidic soils, thereby increasing crop yields.
Biochar can be used as an additive in building materials to improve the lightness, thermal insulation, and durability of concrete or bricks. As a low-carbon material, it also enhances the environmental friendliness of buildings.
Biochar can effectively reduce metal oxides during the smelting process, improving metal recovery efficiency. It can serve as an alternative to traditional reducing agents such as coke, charcoal, and coal.
Adding biochar to the feed of ruminants can adsorb methane precursors in the rumen, reducing methane production and emissions, thereby mitigating the negative environmental impact of livestock farming.
Biochar produced by the carbonizer machine has a high calorific value, making it suitable as an alternative industrial fuel for energy-intensive industries or as charcoal for BBQs.
Biomass is pretreated through drying and crushing to meet the feeding requirements of the carbonization furnace.
A large-inclination belt conveyor transports the prepared biomass into the carbonization kiln continuously.
The continuous carbonization furnace is preheated for approximately 60–90 minutes. Once the temperature reaches the required level, the carbonization process begins. During this process, the biomass undergoes three main phases:

During carbonization, the volatile components in biomass generate a large amount of syngas, including hydrogen (H₂), methane (CH₄), ethane (C₂H₆), and carbon monoxide (CO). This gas is purified and recycled to provide heat for the charcoal carbonization furnace. Reference Data:
The high-temperature biochar enters the discharge system, where it is cooled through a jacketed water-cooling structure. Circulating cooling water flows continuously to remove heatr from the biochar, reducing its temperature to ≤45 °C. This process effectively prevents spontaneous combustion and facilitates safe storage and transportation. Driven by the screw device, the cooled biochar is then transferred to the collection bin.

Flue Gas Emission:
The final flue gas undergoes multi-stage purification treatment that meets EU environmental standards. This advanced flue gas dedusting technology integrates cooling, denitration, desulfurization, and wet electrostatic precipitation to achieve clean and safe emissions.
