Quantile monetary values in USD per unit weight of amendment (top row) and per unit weight of feedstock (bottom row), for agronomically-beneficial components in biologically (60 °C compost) and thermochemically-treated HSW. Agronomic components include plant-available N (NH₄⁺+ NO₃^–), P, K, Ca, Mg, S, micronutrients (B, Cu, Mn, Zn), and the contribution of the CEC toward retention of plant-available K⁺, Ca²⁺, and Mg²⁺, CaCO₃ equivalency, and BC₊₁₀₀. Values are based on nutrient content in HSW (Table 3, Supplementary Table 2) and market prices of agronomic components (Supplementary Table 3).
