Overview of Biodiesel Production Components

When producing biodiesel, each ingredient is a critical input in determining the final cost per unit of fuel. The traditional inputs include:

Vegetable oil as the primary feedstock (in this case, avocado oil traditionally, and now coconut oil).
Methanol, which acts as a key reagent in the transesterification reaction.
Potassium Hydroxide (KOH) as a catalyst.
Electricity for heating, mixing, and maintaining the reaction at optimum conditions.

With the addition of coconut oil into the item list, we get an extra option for feedstock. Coconut oil possesses distinct characteristics including a different price range and potential yield, which can affect the cost metrics of the biodiesel produced.

Inputting Coconut Oil into the Item List

The following table displays the original input components for the biodiesel production process along with the new entry corresponding to coconut oil. The original setup for avocado oil biodiesel is retained for reference and comparison.

Revised Item List Including Coconut Oil

Item	Quantity	Price Range (PHP)
Avocado Oil	100 ml	P30 - P50
Methanol	20 ml	P0.80 – P1.20
Potassium Hydroxide (KOH)	0.85 g	P0.085 – P0.225
Electricity (Heating/mixing)	0.5 kWh	P5 – P7.5
Coconut Oil	100 ml	P7.71 - P11.43
Total Cost (100 ml Biodiesel)	100 ml	P35.885 – P58.955

In this table, avocado oil remains the primary traditional feedstock, while coconut oil is introduced as an additional option. The estimated price range for coconut oil is derived from dividing a known retail range for a 350 ml bottle (₱27 - ₱40) to extrapolate a value for 100 ml. This alternative can serve as an excellent comparative benchmark when evaluating production costs.

Biodiesel Production Cost Analysis Using Coconut Oil

When substituting avocado oil with coconut oil in the biodiesel production process, adjustments must be made to account for differences in oil pricing and yield conversion efficiency. Here is an analysis of the key factors:

Cost Breakdown for Coconut Oil Biodiesel

To derive the cost for producing 100 ml of biodiesel using coconut oil, it is important to understand not only the raw price of the oil but also the additional costs from chemicals and electricity. Considering the following assumptions:

Assumptions

Coconut Oil Pricing: For 100 ml, the price is estimated between P7.71 and P11.43.
Methanol Cost: P0.80 – P1.20 per 20 ml.
KOH Cost: P0.085 – P0.225 per 0.85 g.
Electricity Cost: P5 – P7.5 per 0.5 kWh.

The biodiesel synthesis process using coconut oil typically yields a conversion efficiency that can be assumed to be similar to that using avocado oil. With these costs, an updated calculation for the production of 100 ml biodiesel using coconut oil might be structured as follows:

Calculation

The raw material cost for coconut oil is factored together with the added costs from methanol, KOH, and electricity. While the values for these chemicals do not change, their percentage contribution to the overall cost might be slightly lower if the coconut oil offers cost savings compared to avocado oil. For instance:

Oil Cost for 100 ml: P7.71 - P11.43
Methanol: P0.80 - P1.20
KOH: P0.085 - P0.225
Electricity: P5 - P7.5

This keeps the total cost range for 100 ml biodiesel approximately in the same bracket (P35.885 – P58.955), but when substituting avocado oil with coconut oil, the potential cost reduction on the oil component may lead to overall more competitive pricing. For detailed cost recalculations, one could adjust the expected yield or even the chemical usage if the process conditions vary.

Cost per Gallon Comparison

For an easier field-level comparison, consider the cost per gallon for biodiesel produced using each type of oil. The original framework provides:

Avocado Oil Biodiesel: 3.785 L (1 gallon) costs approximately P1,703.25.

If coconut oil’s intrinsic cost is lower due to its market price—coupled with its potential for a high yield (e.g., a conversion yield in the vicinity of 95% as noted in some analyses)—the cost per gallon for coconut oil based biodiesel could potentially fall in the range:

Estimated Coconut Oil Biodiesel: Approximately P519.43 – P619.91 per gallon, based on cost extrapolations over the production process.

This reduction in cost per gallon is indicative of how feedstock selection can significantly influence the overall economic efficiency of biodiesel production, especially when aiming for large-scale applications.

Aircraft Fueling Costs Comparison

The fueling costs for aircraft are calculated based on the volume required and the cost per unit volume of biodiesel. The original item list provides fueling costs for biodiesel derived from avocado oil:

Aircraft Type	Fuel Capacity (Liter)	Fuel Capacity (Gallons)	Total Cost (PHP) using Avocado Oil Biodiesel
Cessna 172	200 L	52.8 Gallons	P89,848.80
ATR 72 (Regional Jet)	2,500 L	660 Gallons	P1,124,145.00
Boeing 737 (Commercial Jet)	26,000 L	6,780 Gallons	P11,703,357.50
Boeing 777 (Large Aircraft)	90,000 L	23,780 Gallons	P40,470,435.00

Should coconut oil be utilized, and based on the estimated lower cost per gallon of coconut oil biodiesel (approximately P519.43 – P619.91 per gallon), aircraft fueling costs may see a substantial decrease in expense. Although the exact numbers depend on scale and actual market conditions, the economic potential of coconut oil in reducing operating costs is significant. For example, applying the lower cost estimate would reduce the fueling costs for smaller aircraft by nearly a factor of three relative to avocado oil biodiesel.

Detailed Cost Comparison and Economic Insights

Below is an expanded table that provides an integrated look at both feedstocks, detailing available quantities, cost ranges, and the resultant production costs:

Integrated Cost Breakdown Table

Item	Quantity	Price Range (PHP)	Comments
Avocado Oil	100 ml	P30 - P50	Traditional cost base for biodiesel feedstock
Coconut Oil	100 ml	P7.71 - P11.43	Alternative feedstock with lower raw cost
Methanol	20 ml	P0.80 – P1.20	Essential reagent in transesterification
Potassium Hydroxide (KOH)	0.85 g	P0.085 – P0.225	Catalyst for the biodiesel reaction
Electricity (Heating/mixing)	0.5 kWh	P5 – P7.5	Energy requirement for process temperature and mixing
Total Cost (100 ml Biodiesel) – Avocado Oil	100 ml	P35.885 – P58.955	Based on aggregated input costs
Estimated Total (100 ml Biodiesel) – Coconut Oil	100 ml	Lower component due to oil cost reduction*	*Potential to further reduce total cost per unit depending on scale

The cost integration reveals that switching to coconut oil can considerably decrease the feedstock cost in biodiesel production. When the low-cost efficiency of coconut oil is factored in through the transesterification process, even modest yield improvements can translate to significant savings on a per gallon basis. This could result in lowered overall fuel costs for aviation applications.

Practical Considerations in Feedstock Substitution

It is important to consider several practical aspects when opting to substitute coconut oil for avocado oil in biodiesel production:

Availability and Market Fluctuations

Market conditions affect the availability and price stability of both oils. Coconut oil, especially in regions like the Philippines, benefits from a robust production base. However, seasonality, climate events, and regional economic policies can influence pricing. Therefore, continuous monitoring of market trends is critical.

Chemical Reaction Efficiency and Yield

The transesterification reaction—a critical chemical process in converting oil into biodiesel—has high conversion rates for both avocado oil and coconut oil. Often, coconut oil exhibits similar or slightly improved yield percentages (around 95%) compared to other vegetable oils, making it a competitive replacement in the equations that determine biodiesel output.

Environmental and Economic Benefits

The use of coconut oil can carry additional environmental benefits since it is often produced locally with lower transportation costs. Additionally, lower production costs lead to favorable economic outcomes, particularly relevant for regions aiming to reduce dependency on fossil fuels. For aviation fueling costs, the translation of these savings offers potential operational efficiencies and reduced carbon emissions.
