In today’s world, there is a high demand for diesel fuel. There are several problems associated with traditional energy sources such as:

• Pollution• Foreign dependency• Nonrenewable resources

Biodiesel solves several of these problems: • Produces fewer air pollutants and harmful

greenhouse gases • Renewable, domestically produced resource • Utilizes otherwise problematic waste products

Int roducti on

The objectives of this project were:• To study the production of biodiesel in waste

cooking oil (WCO) and in waste coffee grounds (WCG)

• To examine biodiesel as a practical energy resource

• To investigate the effects of variations in reaction times during WCO extractions

• To determine the effects of using various WCG mixtures (5% NaOH, 5% KOH, and 10% KOH)

Objecti ves

• Waste coffee grounds (WCG)1. Weigh out coffee grounds2. Combine with methanol3. Allow reaction to proceed for 2.5 hours, taking samples every 30 minutes

Mater ia l s and Methods

Conc lus ions

• Relationships determined from the WCO data:

• The longer the reaction time, the higher the percent recovery of biodiesel and the less time required for separation

• Glycerol yield with different reaction times during WCO extractions remained relatively constant

• WCO and WCG extraction purity to be determined

• Need to continue research on lowering cost production of biodiesel for both WCO and WCG production methods
