Member of the International Biochar Initiative (IBI) and the Australia New Zealand Biochar Industry Group(ANZBIG )

PyroGreen Energy Technology Co., Ltd. is a technology enterprise specializing in green renewable energy, green chemical engineering, and energy conservation and environmental protection. Our expertise encompasses advanced biochar production equipment, including our core innovation: a rotary kiln biochar carbonization system based on internal indirect heating technology. This system represents a leap forward in efficient and controllable thermochemical conversion.

What is Biochar?

Biochar is a carbon-rich solid material made through a thermochemical conversion process. The essence of its preparation is to pyrolyze organic biomass at high temperatures in an oxygen-limited or oxygen-free environment, thereby stabilizing carbon.

Soil Functions and Benefits of Biochar

Functional Categories	Brief Introduction of Scientific Mechanisms and Effects
Carbon Sequestration & Stabilization	The pyrolysis process reorganizes unstable organic carbon into highly aromatic stable structures, significantly extending its residence time in the soil
Soil Physical Improvement	The developed porous structure helps reduce soil bulk density and increase porosity, enhancing water-holding capacity and aeration.
Soil Chemical Improvement	Rich surface functional groups and huge specific surface area provide strong ion exchange and adsorption capabilities, improving soil fertility retention.
Soil Biological Promotion	The porous structure provides habitat and physical protection for soil microorganisms, promoting diversity and activity.

Core Technology: The Rotary Kiln Indirect Pyrolysis System

Our flagship biochar kiln solution is an indirect-heating rotary kiln biochar production system. This continuous rotary kiln is engineered for efficiency, consistency, and environmental performance, making it premier biochar production equipment.

Advantages of Our Rotary Kiln Design

The rotary kiln design is central to our system's performance. As a biomass rotary kiln, it operates on distinct technical principles:

Indirect Heating Method:	Heat is transferred through the rotating kiln wall, preventing direct contact between biomass and flame. This ensures precise temperature control and uniform heat distribution.
Anoxic Environment Control:	The sealed rotary kiln design maintains the necessary oxygen-free atmosphere, maximizing solid carbon yield.
Continuous & Controllable Process:	The continuous rotary kiln motion allows for constant flipping and advancement of material. Coupled with precise control over temperature and residence time, it guarantees consistent product quality.
Environmentally Friendly Operation:	The closed system allows pyrolysis gases to be recycled for process heating, enabling energy circulation and controlled emissions.

The Scientific Pyrolysis Process

Drying & Preheating:	Biomass absorbs heat, removing moisture.
Pyrolysis & Carbonization:	Under oxygen-limited, moderate-high temperature conditions within the rotary kiln, organic components (cellulose, hemicellulose, lignin) undergo chemical breakdown and recombination, forming a solid carbon skeleton.
Cooling & Stabilization:	The hot biochar is cooled under controlled conditions to become a stable final product.
