Case Study: Achieving 80% Odor & Toxic Gas Reduction on a Pig Farm with NEMA 1
Project: A Scientific Evaluation of Odor & Toxic Gas Reduction in Pig Farms Using Organic Carbon Technology.
Location: Tan Kim Farm, Phu Binh, Thai Nguyen.
Implementation Period: July 2025.
Introduction: Solving The Odor Problem
This report details a powerful solution for odor and toxic gas reduction in pig farming environments. The objective is to scientifically assess the effectiveness of NEMA 1 (Organic Carbon technology) in neutralizing foul odors and harmful gases, thereby protecting livestock health, improving working conditions, and promoting sustainable farming practices.
1. The Source of Odor & Air Pollution in Pig Farms
High-density industrial pig farming generates immense quantities of waste, which is the primary source of severe air quality issues. Without effective treatment, this leads to significant challenges.
Harmful Gas Emissions
The decomposition of manure and urine releases a constant stream of noxious compounds into the air. High concentrations of toxic gases like Ammonia (NH_3) and Hydrogen Sulfide (H_2S) are the main culprits behind the pungent, foul odors that plague many farms and surrounding communities.
2. NEMA 1: The Solution for Odor & Toxic Gas Reduction
NEMA 1 is a breakthrough Organic Carbon technology from Japan, specifically designed to provide a safe, sustainable, and powerful solution for odor control and toxic gas reduction in livestock facilities.
3. Implementation for Maximum Odor Reduction
The project was executed at Tan Kim Farm to verify the solution’s performance in achieving significant odor and gas reduction under real-world conditions.
4. Scientific Results: Measuring the Reduction in Odor & Gas
To provide objective proof, odor and gas levels were measured using a professional-grade Shinyei OMX-ADM meter before and after the NEMA 1 application.
5. Data Analysis: Before & After NEMA 1 Application
5.1. Baseline Measurements (Before NEMA 1 Application)
Measurements taken over 3 days before system implementation showed that the concentration of toxic gases and foul odors was at a dangerously high level, frequently exceeding 500 Odor Units (OU). This highlights the urgent need for an effective odor and toxic gas reduction strategy.






5.2. Efficacy Analysis: Before-and-After Comparison of Odor Reduction
The data revealed a dramatic improvement. After just 5 days, odor and gas levels were reduced by an average of 78%, with peak reductions reaching 82%. This confirms the exceptional efficacy of NEMA 1 for odor and toxic gas reduction.

6. Conclusion
The case study conclusively demonstrates that NEMA 1 is a highly effective solution, achieving up to 82% odor and toxic gas reduction. This technology presents a viable, sustainable path for pig farm operators to significantly improve air quality, ensure animal welfare, and maintain good community relations.
