  7. Advantages - -Biomass is renewable -It makes sense to use waste materials where we can. -The fuel tends to be cheap.-Less demand on the fossil fuels.

  8. Disadvantages -Collecting or growing the fuel in sufficient quantities can bedifficult. • Weburn the biofuel, so itmakesgreenhousegases just likefossilfuels do. • Some wastematerials are notavailableallyear round.
