Weight Loss Due to Microorganism (\( L_m \)):

\[ L_m = \left( \frac{W_i (100 - M_i)}{100} + 0.68 \times 10^{0.44M_i - 11.08} \right) \times D \]

Where:

• \( L_m \) is the weight loss due to microorganism, in kilograms (kg).
• \( W_i \) is the weight of incoming stock, in tons.
• \( M_i \) is the moisture content of incoming stock, in percentage (% w.b.).
• \( D \) is the storage period, in days.
