The use of petroleum-based fuels in air transport and the increase oil prices over years have increased fuel costs. Due to this increase, manufacturers airline companies started search for alternative fuels. Since aviation has an important place transportation sector, biomass greatest potential renewable energy sources. Biological substances plant animal origin containing carbon compounds are s...

An experiment was conducted to evaluate growth performances and production of bio-fuel Spirulina platensis (Gomont), bio-oxygen bio-electricity culture media in supernatant three different amount digested poultry waste (DPW), Kosaric medium (KM) as control. Three amounts (concentrations) such 2.0, 4.0 6.0 g/L were allowed digest under aeration. After 17 days, 700 ml grayish coloured taken with ...

Background Biomass-derived jet fuel is an alternative jet fuel (AJF) showing promise of reducing the dependence on fossil fuel and greenhouse gas emissions. Hydroprocessed esters and fatty acids (HEFA) concept is also known as one of the pathways for producing bio jet fuel. HEFA fuel was approved by the American Society for Testing and Materials in 2011, and can be blended up to 50% with conven...

This study was an attempt to produce bio-oil from empty fruit bunches (EFB) of oil palm waste using fast pyrolysis technology. A 150 g/h fluidised bed bench scale fast pyrolysis unit operating at atmospheric pressure was used to obtain the pyrolysis liquid. A comparison of the elemental composition of unwashed and washed feedstock was made in this study. With the five methods of treatment being...

On 1 January 2007, Romania entered the European Union. For that reason Romania must comply with all the EU directives in the field of the management of the environment. In 2007, in Romania, Municipal Solid Waste (MSW) was generally landfilled without pre-treatment and energy valorization absent. Some initiatives are in progress but landfilling is still dominant. The entrance in the EU gave an i...

Biomethane, as a replacement for natural gas, reduces the use of fossil-based sources and supports the intended change from fossil to bio-based industry. The study assessed different biomethane utilization routes for production of methanol, dimethyl ether (DME), and ammonia, as fuel or platform chemicals and combined heat and power (CHP). Energy efficiency and environmental impacts of the diffe...
