Will biomass pyrolysis provide large scale biofuel alternatives to fossil fuels and alternatives to petrochemicals, as compared to the large scale common uses of biomass such as paper industry
Biomass production has three main human uses: for food and fodder production; for energy, such as liquid bio-fuels; for production of materials, not only for construction and paper, but also for wool, cotton etc. Net primary production of biomass has to support Earth's ecosystems as well as the human uses listed above. Ethically, providing food for Earth's people must be given precedence over the other uses, but not necessarily providing high animal products diets. Also, using timber as a construction material to replace (some) energy-intensive steel and concrete will reduce global GHG emissions more than using bio-energy to replace fossil fuel combustion. Overall, bioenergy can only be a minor contributor to future energy--we will have to rely more on other renewable energy sources, and on energy reductions.
Many thanks. However, there is a lot of biomass wastes which have great potential for paper production and biofuels production by pyrolysis. Moreover, these wastes -if not used- may be just burnt to harm the environment. You may see the two reviews mentioned below for a comprehensive discussion:
