DOING 5 t/h biomass carbonization machine intalled in Ghana | Carbon Sink Project in Africa

In June 2026, Doing Company once again delivered an outstanding result: the 5 t/h biomass carbonization machine, custom-engineered for a client in Ghana, has successfully completed installation and commissioning at the project site and is poised to enter formal operation.

Biomass carbonization machine installation site in Ghana

The 5 t/h biomass carbonization machine installed by the DOING engineering team in Ghana comprises the following five core systems:

1. High-Efficiency Drying System

The moisture content of the raw material prior to entering the main carbonization furnace directly impacts the quality and yield of the final biochar. This production line is equipped with a dedicated drying system that utilizes waste heat generated during the carbonization process to pre-dry the feedstock. By significantly reducing the moisture content of the raw material not only enhances subsequent carbonization efficiency but also effectively lowers the project's overall energy costs.

2. Continuous Carbonization System (Core Reactor)

This is the core component of the entire biomass carbonization machine. The system employs high-temperature pyrolysis technology to deeply carbonize biomass in an oxygen-free environment. Featuring a robust double-layer structure, the carbonization unit ensures uniform heating, guaranteeing high fixed-carbon content and consistent quality in the resulting biochar, meeting international market standards.

3. Safe Cooling System

Upon completion of high-temperature carbonization, the biochar exiting the furnace is extremely hot and highly prone to spontaneous combustion if exposed directly to air. This machine is equipped with a multi-stage water-cooled discharge system capable of rapidly lowering the biochar temperature to a safe range within a sealed environment, thereby enabling safe, dust-free, and continuous discharge.

4. Combustible Gas Recovery System

Environmental friendliness and energy efficiency are key advantages of DOING's biomass carbonization machine. During the carbonization process, the biomass generates a large amount of high-temperature syngas. The combustible gas recovery system removes dust and tar from the gases and subsequently reintroduces them into the bottom of the main unit to serve as a heat source for cyclic combustion. This design enables the equipment to achieve thermal self-sufficiency after startup, resulting in significant savings on fuel costs.

5. Exhaust Gas Emission System (Environmental Purification Unit)

To comply with stringent environmental emission standards, a multi-stage exhaust gas purification system has been installed at the Ghana project site. Incorporating environmental protection equipment such as water-film dust collectors and spray towers, the system performs deep purification and filtration of excess flue gas, ensuring that the final emissions meet national environmental requirements.

The project partner operates multiple large-scale biomass processing projects in Africa. Unlike conventional waste reduction operations, this Ghanaian client’s primary focus is on carbon sinks. Consequently, the DOING technical team fine-tuned the temperature control system, residence time, and condensation recovery system. These customized technical adjustments ensure that the biochar fully meets the high standards of the international carbon credit market regarding specific surface area, pore structure, and fixed carbon purity, thereby helping clients successfully secure carbon reduction benefits.

On-site installation and commissioning by Doing engineer

The successful implementation of this 5 t/h biomass carbonization machine in Ghana was made possible by the client's trust and DOING’s comprehensive, one-stop solution, covering everything from initial project design and equipment manufacturing to on-site installation guidance in Ghana.
