What are the disadvantages of biofuels? Also have you learnt about the specific uses of them (like biogas and bioethanol) or just generally? I'm starting to stress!!

A disadvantage of biofuels is that they take up land which could be used to grow crops. Hope this helps. Also, try not to be stressed and just remain calm and take deep breaths before u go into an exam. I get stressed too but I try my best to keep calm by taking deep breaths.

My teacher guessed the disposal of polymers i.e. recycling, incineration, and landfill, to be one 6 marker this year. I also have a feeling that the other 6 marker may be the formation of the atmosphere in chronological order, but I think that may be too nice of them, especially after the biology paper this year.

Takes up land normally used for food. Causes food shortages. Less supply means that the price of things go up. Have to spend huge quantities of cash building all necessary infrastructure eg processing plants, refuelling station car engines to run off the new fuels etc. Biofuels are often also worse in terms of the energy released per given amount used
