BIOGAS AND BIOMETHANE POTENTIAL
Assessing the biogas/biomethane potential and degradation rate of organic matter facilitates a more accurate and comprehensive waste characterization. Most biogas potential testing methods can be applied to a wide range of organic materials.

A Reliable Basis for Investment Decisions

Biogas potential analysis helps us determine the optimal co-substrate ratio, evaluate the dynamics of anaerobic degradation, and identify potential process inhibition.

These parameters and properties provide valuable insight when planning investments in anaerobic waste treatment facilities. Biogas potential is one of the most reliable indicators for assessing the feasibility of waste treatment and waste-to-energy technologies.

Biogas Potential Testing Methods

We use several laboratory methods to determine the biogas potential of organic matter. These methods generally fall into two categories: manometric and volumetric testing. Testing typically lasts 21, 90, 100, or 270 days. With manometric methods, we determine biogas production by measuring pressure changes inside a closed reactor. With volumetric methods, we measure gas production directly using eudiometers, gas collection bags, or gas meters capable of measuring both biogas and methane volume.

At our laboratory, we use the volumetric GS21 method to determine biogas potential. The analysis lasts 21 days and is suitable for all types of organic substrates. We report biogas yield in NL/kg of dry matter.

Biogas Potential Testing According to VDI 4630:2016

Our Ecotechnology Laboratory performs biogas potential testing for a wide range of organic materials in accordance with VDI 4630:2016 and applicable regulations, including the Landfill Regulation (Official Gazette 4/2023).

Quantitative and Comparative Analysis of Waste and Substrates

Using this method, we estimate the amount of biogas generated through the anaerobic degradation of organic materials (such as mixed municipal waste, biodegradable waste, agricultural residues, wastewater treatment sludge, industrial by-products, etc.).

We apply these quantitative and comparative methods to various waste streams and substrates, helping clients identify the optimal co-digestion mixtures and maximize biogas production.

The results provide a clear assessment of the energy potential of materials and help determine the feasibility and efficiency of biological waste treatment processes.

Why Testing Matters

Biogas potential testing plays an important role in:

  • Planning and optimizing anaerobic digestion and biogas production facilities,
  • Evaluating waste-to-energy opportunities,
  • Demonstrating compliance with regulatory requirements for waste recovery operations in Croatia.

 

Clients also use the results to support circular economy projects, feasibility studies, and environmental and energy assessments.

1. REAL SAMPLE COLLECTION

We collect representative field samples directly at client facilities and analyze them in our accredited laboratory in accordance with recognized standards. Our laboratory testing includes physical, chemical, and biological parameters required to define design input values, including load variability and seasonal or operational fluctuations. These data form the foundation for reliable scaling solutions and technology development.

2. DEVELOPMENT OF TECHNICAL SOLUTIONS

Based on the assessment of existing conditions and laboratory results, we develop technical solutions tailored to each client’s requirements. When designing solutions, we consider plant capacity, influent characteristics, discharge requirements (public sewer systems or natural receiving waters), and circular economy principles. To support detailed process development, our laboratory is equipped with reactors, measuring instruments, and pilot-scale systems that allow us to simulate real operating conditions. Through pilot testing, we evaluate process efficiency, optimize operating parameters, and validate treatment concepts before full-scale implementation. This approach significantly reduces investment and operational risk while ensuring long-term sustainability of the selected solution. We also place strong emphasis on optimizing energy, chemical, and resource consumption while minimizing the plant’s environmental footprint throughout its lifecycle.

3. ENGINEERING DESIGN AND PERMITTING

Our multidisciplinary engineering team prepares complete project documentation, from conceptual designs and feasibility studies to detailed engineering documentation and permit applications. All documentation is developed in accordance with current legislation, technical regulations, and applicable standards while maintaining close coordination with clients and regulatory authorities.

4. PLANT ENGINEERING AND INSTALLATION – Complete turnkey plant implementation proposal, including detailed design documentation and commissioning services

We deliver turnkey treatment plants tailored to each client’s needs. Our services include detailed engineering design, equipment procurement and delivery, site organization, installation of process and electrical equipment, and integration of automation and control systems. The final stage includes functional testing and preparation for plant commissioning.

5. CONSTRUCTION SUPERVISION

We provide professional technical supervision during construction to ensure full compliance with project documentation, technical standards, and contractual requirements. We monitor construction quality, installed equipment, and adherence to project timelines.

6. PLANT COMMISSIONING AND STAFF TRAINING

After construction and functional testing are complete, we perform staged commissioning with continuous monitoring of process parameters and adjustment of operating conditions. We also prepare operational manuals and provide professional staff training to ensure safe, efficient, and long-term stable plant operation.

7. POST-CONSTRUCTION TESTING

After project completion, we perform functional and other tests to verify that the treatment plant achieves the required operational parameters and effluent quality.

8. PLANT SERVICE AND MAINTENANCE

We provide preventive and corrective maintenance, scheduled service inspections, and 24/7/365 technical support. Our systematic maintenance approach extends equipment lifespan, minimizes downtime risk, and ensures high operational efficiency.

9. PLANT MONITORING AND OPERATIONAL CONTROL

We implement SCADA and PLC automation and control systems that enable continuous plant monitoring, analysis of key process parameters, and rapid response to operational deviations or fluctuations in wastewater flow and loading. We place particular emphasis on reducing energy, chemical, and labor consumption.

10. PLANT OPTIMIZATION AND RECONSTRUCTION

We perform technical assessments of existing systems to identify capacity limitations, energy losses, and operational inefficiencies. Based on our findings, we recommend retrofits, upgrades, and modernization of technological process lines to improve efficiency, ensure compliance with new regulatory requirements, and extend plant service life.
