Biodiesel Production Using Eggshell as a Catalyst
A sustainable biodiesel production project that turns waste eggshells into a heterogeneous catalyst, enabling the transesterification of vegetable oils or waste cooking oils into renewable fuel.
About the Project
Turning Eggshell Waste into a Renewable Energy Tool
This project explores the sustainable production of biodiesel by utilizing waste eggshells as a heterogeneous catalyst. Eggshells, primarily composed of calcium carbonate (CaCO₃), are processed through calcination to produce calcium oxide (CaO) — an effective, low-cost catalyst used in the transesterification of vegetable oils or waste cooking oils.
The Challenge & The Approach
From Food Waste to Clean Fuel Production
The Problem
Eggshells are generated in large quantities as food industry waste, while conventional biodiesel catalysts are often costly or environmentally taxing to produce, limiting the accessibility and sustainability of biodiesel production.
The Catalytic Approach
Waste eggshells are converted through calcination into calcium oxide (CaO), an effective heterogeneous catalyst used in the transesterification reaction that converts vegetable or waste cooking oils into biodiesel.
How It Works
From Eggshell to Biodiesel
Eggshell Collection
Waste eggshells, composed mainly of calcium carbonate (CaCO₃), are collected as the raw material.
Calcination
The eggshells are processed through calcination to convert CaCO₃ into calcium oxide (CaO).
Transesterification
The CaO catalyst drives the transesterification of vegetable or waste cooking oils into biodiesel.
Innovation
What Makes This Approach Distinct
Waste-Derived Catalyst
Uses a food-industry by-product instead of costly synthetic catalysts.
Low-Cost Process
Calcination offers an effective and economical route to a functional catalyst.
Circular Resource Use
Combines waste-oil and waste-eggshell streams into one sustainable production cycle.
