Everything You Need to Know About Jatropha

Jatropha is a genus of nearly 175 species of shrubs, low-growing plants, and trees.  However, discussions of Jatropha as a biodiesel feedstock are actually means a particular species of the plant, Jatropha curcas. The plant is indigenous to parts of Central America, however it has spread to other tropical and subtropical regions in Africa and Asia. What is Jatropha? Jatropha curcas is a perennial shrub that, on average, grows approximately three to five meters in height. It has smooth grey bark with large and pale green leaves. The plant produces flowers and fruits are produced in winter or throughout the … Continue reading

A Primer on Biodiesel

Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources. This biofuel is a mixture of fatty acid alkyl esters made from vegetable oils, animal fats or recycled greases. Where available, biodiesel can be used in compression-ignition (diesel) engines in its pure form with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulphur and aromatics. It is usually used as a petroleum diesel additive to reduce levels of particulates, carbon monoxide, hydrocarbons and toxics from diesel-powered vehicles. When used as an additive, the resulting diesel fuel may be called B5, B10 … Continue reading

What are Biofuels

Biofuel refers to liquid or gaseous fuels that are predominantly produced from biomass. A variety of fuels can be produced from biomass resources including liquid fuels, such as ethanol, methanol, biodiesel, Fischer-Tropsch diesel, and gaseous fuels, such as hydrogen and methane. Resource Base for Biofuels Production The biomass resource base for biofuels production is composed of a wide variety of forestry and agricultural resources, industrial processing residues, municipal solid wastes and urban wood residues. The agricultural resources include grains used for biofuels production, animal manures and residues, and crop residues derived primarily from corn and small grains (e.g., wheat straw). … Continue reading

Zero-Waste Kitchens and Low-Energy Cooking

Food is the single largest source of waste. Worldwide, we throw away about a third of our food. More food ends up in landfills than plastic or paper. The enormous amount of wasted food depends on our cooking and eating habits.  Generally, it is easy to be sitting at home, in front of your television, consuming whatever you want then throwing every‑thing in the trash. But have we ever thought, where does the garbage go? Zero-Waste Kitchens Given that most of the domestic waste originates in the kitchen, a green home should definitely include a zero-waste kitchen. Zero waste kitchens is … Continue reading

Biofuels in Jordan: Perspectives

Jordan has good biofuels production potential in the form of crop residues, agro-industrial wastes and urban wastes. Biomass energy sector in Jordan is slowly, but steadily, developing. As per a recent World Bank report, the country is currently generating 3.5MW of power from biomass resources which represent 0.1% of the total energy demand in the country. However there is no available data on the amount of biofuels produced in Jordan. Jordan produces significant amount of biofuel feedstock in the form of lignocellulosic biomass, used cooking oil, animal tallow, agro-industrial wastes, industrial effluents etc.  In Jordan, transportation sector alone is responsible of 51% of final … Continue reading
