Comprehensive feedstock analysis to optimize your biogas production

Digestate Testing

1. Total Solids (TS): Measures the remaining solids post-digestion.

2. Volatile Solids (VS): Indicates the efficiency of organic matter breakdown.

3. Chemical Oxygen Demand (COD): Assesses the remaining organic compounds.

4. Ammonia Concentration: Monitors ammonia levels to prevent toxicity.

5. Volatile Fatty Acids (VFAs): Checks for accumulation that may indicate process imbalance.

6. pH Levels: Ensures the digestate remains within the optimal range for microbial activity.

7. Nutrient Content (N, P, K): Evaluates the quality of digestate as a bio-fertiliser.

8. Pathogen Levels: Ensures the digestate meets safety standards for use as fertiliser.

Feedstock Testing

1. Total Solids (TS): Measures the total amount of solids in the feedstock.

2. Volatile Solids (VS): Indicates the proportion of organic matter that can be converted into biogas.

3. C/N Ratio: Indicates the balance for optimal microbial activity.

4. Fibre Analysis: Determines the amounts of key components like cellulose, hemicellulose, lignin essential for biogas production.

5. Biochemical Methane Potential (BMP): Estimates the maximum methane production potential of feedstock.

6. pH Levels: Ensures the feedstock is within the optimal range for microbial activity.

7. Nutrient Content (N, P, K): Evaluates essential nutrients for microbial growth.

8. Inhibitory Substances: Detects potential inhibitors like heavy metals or ammonia.
