Table 15 Computation of biodiesel production cost.

From: RSM integrated GWO, Driving Training, and Election-Based Algorithms for optimising ethylic biodiesel from ternary oil of neem, animal fat, and jatropha

Step

Description

Amount (in USD)

Feedstock

Oil cost for 1 kg of biodiesel production = (quantity × neem oil cost per kg + quantity × animal fat cost per kg + quantity × Jatropha oil cost per kg) = (0.3 * $ 0.84 + 0.3 *$ 0.6 + 0.4 * $ 0.78)

$ 0.75

Catalyst dosage consumed for 1 kg of biodiesel

0.00915 kg

$ 0.022

Ethanol required for 1 kg of biodiesel

0.02953 kg

$ 0.027

Processing cost

Transesterification time (h) × units consumed × cost per unit = (1.124 h × 0.8 × $ 0.054)

$ 0.049

Net cost (Feedstock + 

Catalyst + Ethanol + processing)

($ 0.75 + $ 0.022 + $ 0.027 + $ 0.049)

$ 0.848

Overhead cost (10% of net cost)

10% of $ 0.848

$ 0.0848

Biodiesel production cost per kg

Cost (net + overhead) = 0.848 + 0.0848

$ 0.9328
