• Korean food waste takes about 30% of total organic wastes (6.6million ton/year). The water content of food waste is about 90%. Because of the characteristics, it is difficult to treat the waste by conventional technologies like land filling or incineration.

• KIER developed a two-phase anaerobic digestion process in which acidic fermentation and methane formation were done in separate reactors. The technology was found to be quite effective for the treatment of Korean food waste.

• After a series of test runs, the technology was commercialized. Two full scale commercial plants have been constructed to treat food waste and produce methane. The research for the electricity generation using methane was finished in 2008.

Began in 2002 as demonstration project.

Biodiesel is used 1.5% in 2009, and 3.0% in 2012 of total diesel consumption.

- 0.5% increases in each year

BD5 is commercialized in Korea in 2006, marked as the first country in Asia.

BD20 is limited on the vehicles enabling to repair in their own facilities due

to the technological problems.

- Introduction of E3 - Biogas?

- Introduction of biogas

Scenario 1 is effective from September, 2015!

• Korean supporting policy for renewable energy implementation is changed from “Subsidy” to “Mandatory” (RPS (2012), RFS (2015) and RHO (2016))

• Bioenergy will play a key role for realizing the sustainable society in Korea

• Securing stable supply of the feedstocks will be the most challenging issue

• Organic wastes and energy crops may be the promising candidates as the feedstocks for bioenergy production
