•   Identify the raw material used to make biofuel and biogas. Identify alternative raw materials that can also be used to produce the same product.

•   List possible uses for biofuel and biogas.

•   Write the chemical formulas for biofuel and biogas. Explain the statement that biofuel and biogas still represent energy-rich compounds. Compare the chemical composition of each substance to carbon dioxide, which is the product of the complete oxidation of glucose.

•   What are some of the problems associated with the processes used to produce each of these substances?

Exact same uses as petroleum-based fuels. Power vehicles, machines, heat our homes, etc.

Biogas from anaerobic digestion is normally composed of methane (CH4), carbon dioxide (CO2), and traces of ammonia (NH3), hydrogen sulfide (H2S). CH4 is often between 40 and 70%.

A lot of energy is required to produce this form of energy, almost 1 to 1, which makes it not an efficient source of fuel. In other words, it is an extensive process converted vegetable oil into bio-diesel, for instance, and methane is also a very potent greenhouse gas.
When you like a flower, you just pluck it out.
But when you love a flower, you water it daily.
The one who understands this, understands life.

- That's the difference between I like you and I love you.
