The 2005 Volvo FlexiFuel S40 was one of the first E85 flexible
fuel cars produced by a Swedish automaker. The Volvo Flex-
iFuel is now offered on the European market.

Biofuel is defined as solid, liquid or gaseous fuel obtained
from relatively recently lifeless or living biological ma-
terial and is different from fossil fuels, which are derived
from long dead biological material. Also, various plants
and plant-derived materials are used for biofuel
Globally, biofuels are most commonly used to power
vehicles, heat homes, and for cooking. Biofuel industries
are expanding in Europe, Asia and the Americas. Recent
technology developed at Los Alamos National Lab even
allows for the conversion of pollution into renewable bio
fuel. Agrofuels are biofuels which are produced from
specific crops, rather than from waste processes such as
landfill off-gassing or recycled vegetable oil.
There are two common strategies of producing li-
quid and gaseous agrofuels. One is to grow crops high in
sugar (sugar cane, sugar beet, and sweet sorghum) or
starch (corn/maize), and then use yeast fermentation to
produce ethyl alcohol (ethanol). The second is to grow
plants that contain high amounts of vegetable oil, such
as oil palm, soybean, algae, jatropha, or pongamia pin-
nata. When these oils are heated, their viscosity is re-
duced, and they can be burned directly in a diesel en-
gine, or they can be chemically processed to produce
fuels such as biodiesel. Wood and its byproducts can also
be converted into biofuels such as woodgas, methanol or
ethanol fuel. It is also possible to make cellulosic eth-
anol from non-edible plant parts, but this can be difficult
to accomplish economically..
Sugar cane can be used as a biofuel or food.
Biomass or biofuel is material derived from recently liv-
ing organisms. This includes plants, animals and their
