This study has been conducted to evaluate environmental values of high acid value waste oil recycling technology and suggest improvement directions of the recycling technology. As the result of comparing with vegetable oil fatty acid methyl ester(FAME), total environmental impact of recycled FAME showed 96% of vegetable oil FAME. When considering each impact category, environmental impacts of recycled FAME appeared to 54%, 15%, 99% of resource depletion, global warming, and human toxicity. Reducing water usage and recycling waste water can lower the environmental impact of recycling process.
