Chemical composition of biomass - Biomass as Energy Source: Resources, Systems and Applications - page 52

We are currently on the doorstep of the industrialized biocarbon era. To cross the threshold, we
will have to develop new knowledge and know-how in many sectors of society. We will also have
to be patient and accept that there will initially be some drawbacks with the new systems because
the problems to be solved along the way are more challenging than those encountered during
the adoption of fossil fuels in the last century. However, we have a great advantage compared
to the pioneers who first introduced widespread use of fossil fuels in that our technological
sophistication and understanding of science have increased enormously. This puts us in a strong
position as we strive to develop sustainably and to develop efficient and non-harmful methods
for energy conversion.

2.8 QUESTIONS FOR DISCUSSION

• Why is biomass a suitable chemical resource for production of so many different types of

products?

• How can biomass compete with oil and natural gas for production of plastics, textiles and other

chemical products?

• What is the difference between cellulose, hemicellulose, starch and lignin?

• What do you believe biomass will be used for in the future? Any totally new applications?
