Liquid Fuels From Biomass In The Era Of Bioeconomy

Biomass solid fuels, especially wood pellets, have gained great attention so that their use continues to increase, as a means of lowering the temperature of the earth. The estimated use of world wood pellets will reach 50 million tonnes / year by2024 while Korea and Japan alone will reach 20 million tonnes / year in the next 3-4 years. Why is the biomass-fuel solid getting so much attention? This is due to the large coal-fired power plants that have been able to gradually use the wood pellets, even new plants are also built specifically using wood pellets or other biomass fuels such as palm kernel shells or wood chips. What about liquid fuels from biomass? Liquid fuel has a large portion as a vehicle fuel or industry, both derived from fossil and from biomass. Bioenergy (energy from biomass which includes solid, liquid and gas) currently accounts for about 10% of total global energy use, or equivalent about 53 EJ / year (about 6 minutes of solar radiation to the earth). Petroleum cons…

Go Biomass, Go Bioeconomy!

"Verily in the creation of the heaven and the earth, and the alternation of night and day there are signs for the intelligent (ulil albab). Those who remember Allah while standing or sitting or lying down and they are thinking about the creation of the heaven and the earth - (then say) 'Our God, you have not created this in vain, Glory to You, so guard us from the torment of hell ". (Qur'an Surah 3: 190-191)
Energy is at the foundation of various economic activities. To heat, cool, illuminate, communication and various computer systems, transportation, mechanical work always requires energy. Currently most of the energy comes from fossil fuels that are bad for the environment in the form of rising carbon dioxide (CO2) concentration which causes climate change and global warming problems. In addition, the fossil fuel in value is also unsustainable because of its limited resources, so the key words of energy development for the present and future is sustainability. In …
