Small Scale Trials

Every organic waste stream holds untapped value when transformed into biochar.
Through controlled, low-risk pyrolysis experiments at 400 °C, 550 °C, and 700 °C, we evaluate feedstock quality, composition, and performance. Results are used to determine compliance with International Biochar Initiative (IBI) Standards, assess suitability for soil applications and carbon credit eligibility, and define pathways for further research and development.

Objectives

Assess the physical characteristics of the feedstock
Ensure the biomass is in optimal conditions of moisture content and particle size

Project Phases

Feedstock Characterization
The process begins with a detailed assessment of the feedstock’s physical and quality attributes, such as moisture content, particle size, and flowability, to ensure proper preparation and compatibility with with our pilot system.
Pilot System Process Flow Assessment
Based on the characterization results, we evaluate the feedstock’s flow behavior within our system to verify stable operation and identify any adjustments needed for optimal processing.
Three-Temperature Scenario Trial
We conduct a controlled processing trial across three defined temperature scenarios (400 °C, 550 °C, and 700 °C). This approach provides insight into how thermal conditions influence biochar yield, quality, and system performance.
Biochar Sampling and Laboratory Testing
A representative biochar sample from the trial undergoes laboratory testing to quantify key quality parameters relevant to the technical and commercial objectives.
Basic Biochar Report
All findings are consolidated into a Basic Biochar Report, delivering a technical evaluation of biochar quality and actionable insights to support next steps.

Large Scale Trial

Biochar Reactors provide state-of-the-art pyrolysis technology for converting agricultural, forestry, and organic waste into high-quality biochar. We design and manufacture scalable, cost-effective systems for sustainable resource recovery.

Objectives

Validate reactor integrity and confirm stable, reliable mechanical and operational performance during continuous pyrolysis.
Determine daily biomass throughput under real operating conditions.
Define optimal operating parameters to maximize biochar yield and overall efficiency.

Project Phases

Feedstock Assessment
It begins with a physical and quality assessment of the feedstock, evaluating moisture, flowability, and other critical parameters. Based on results, we recommend pretreatments, such as drying or grinding, to ensure optimal processing. Multiple feedstock types can be assessed.
Trial Design & Processing Strategy
Once the feedstock profile is defined, we evaluate its behavior in the Single Train Unit (STU). As a baseline, we recommend a three-day processing trial, adjustable to the project needs. These trials help establish expected daily production rates and system performance.
Biochar Quality & System Performance Analysis
Upon completion, we deliver a comprehensive biochar and system performance report aligned with IBI standards. This includes a basic Life Cycle Assessment (LCA) that estimates carbon sequestration potential and indicates possible carbon credit generation.

Product Development

We help customers to unlock new markets by developing differentiated, high-performance biochar products. We design and execute structured experimental programs tailored to applications in agriculture, filtration, industrial additives, composite materials, and more. Each development cycle follows a rigorous engineering approach to ensure technical feasibility, product quality, and market readiness.

Objectives

Objectives

Develop high-value biochar products tailored to customer concepts and market needs, enabling the creation of new commercial opportunities.
Optimize biochar properties for targeted applications, including agriculture, filtration, industrial additives, and composites, by evaluating and enhancing key parameters such as surface area, porosity, particle size, bulk density, and Cation Exchange Capacity (CEC).

Project Phases

Project Phases

Requirement Definition & Concept Alignment
We begin by understanding the customer’s product vision, target application, performance expectations, and market goals. This phase ensures a clear scope and alignment on the intended product outcome.
Feedstock & Biochar Property Assessment
We analyze the biochar’s baseline physicochemical properties, including:
Surface area and porosity (adsorption capacity)
Particle size distribution
Bulk density
Cation Exchange Capacity (CEC)
These parameters guide feasibility and determine suitability for the target application.
Experimental Design & Engineering Planning
Based on the property assessment, we design structured experiments that explore potential enhancements and modifications. Each test follows an engineering workflow and adheres to ASTM standards to ensure repeatability and accuracy.
Laboratory Testing & Product Optimization
We conduct targeted laboratory trials to evaluate product performance under different formulations or conditions. Results are used to optimize functional properties—such as contaminant adsorption, nutrient retention, or compatibility with composite matrices.
Performance Validation for Target Application
Product prototypes are evaluated against industry benchmarks and application-specific requirements (e.g., soil improvement metrics, filtration efficiency, composite integration behavior).
Final Product Reporting & Recommendations
All results are consolidated into a technical report detailing:
• Product performance
• Feasibility validation
• Recommended improvements
• Potential market applications
This report supports customer decision-making for scaling, certification, and commercialization.
