Odor Impact Assessment

Odor Impact Assessment

Accredited Plume Method According to HRN EN 16841-2:2016

Odor Impact Assessment – Plume Method According to HRN EN 16841-2:2016

At our Ecotechnology Laboratory, we are accredited to perform on-site odor impact assessments using the plume method in accordance with HRN EN 16841-2:2016. The method is described under the Waste Management Regulation (Official Gazette 106/2022).

The plume method evaluates how odor emissions spread from sources such as composting facilities, landfills, industrial plants, and wastewater treatment facilities into the surrounding environment.

Quality Requirements for Waste Recovery Processes

The Regulation on End-of-Waste Criteria (Official Gazette 55/2023) also requires odor impact assessment as part of the quality criteria for recovered materials and products after waste recovery processes.

Together with other analyses, odor impact testing helps demonstrate that the use of recovered materials will not negatively affect human health or the environment.

Field Testing

At least two trained assessors (panelists) carry out field testing simultaneously by moving downwind from the emission source and identifying points where odors can or cannot be detected. During testing, we also collect meteorological data near the measurement site.

Using these observations, we determine the extent of odor plume dispersion under current weather conditions. The results allow us to map odor dispersion patterns, providing valuable data for air quality management and minimizing environmental impact.

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.
