Please have a look to the bib entry before the entry Chan2015 with the first error: 

@misc{Sparta2015,
title={Industries: Pharmaceuticals and Biotechnology Regulations Overview},
author={{Sparta Systems Inc.}},
year={2015},
howpublished={\url{http://www.spartasystems.com/industries/pharmaceutical-biotech/regulations-overview/},
note={Accessed: 14/10/2015},
}

There is a } missing at the end of the howpublished field! You need one pair of {} for the howpublished, a second pair for the \url command: \howpublished={\url{...}},.

Change it to (see the }}, at the end of howpublished!): 

@misc{Sparta2015,
  title={Industries: Pharmaceuticals and Biotechnology Regulations Overview},
  author={{Sparta Systems Inc.}},
  year={2015},
  howpublished={\url{http://www.spartasystems.com/industries/pharmaceutical-biotech/regulations-overview/}},
  note={Accessed: 14/10/2015},
}

Now you can see, that you should check one by one the reported errors. best to do check the first error, correct it, recompile, check the next first error, ...

An second example for another error. See the entry: 

@misc{ILO2015,
author={The International Labour Organisation},
title={Where will unemployment be the highest over the next five years?},
url={\url{http://www.ilo.org/global/about-the-ilo/multimedia/maps-and-charts/WCMS_336950/lang--en/index.htm},
note={Accessed on 11/10/2015},
year={2015}
}

Formal there is a closing } missing, but you do not need to add command \url in an bib field url: so change it to (delete \url{!): 

url={http://www.ilo.org/global/about-the-ilo/multimedia/maps-and-charts/WCMS_336950/lang--en/index.htm},

In the comments to your question and in the answer of @egreg you can find hints to the other errors you have in your bib file. Please follow them and check one by one the first returned error in your bib file. Why the first error? It could be that this error causes following errors. So correct the first error, compile, check and correct the now first error, compile, ...

Correct all errors and warning you get from your bib file!
