Whats left of Fisons Fertiliser, Essex

I had a couple of days off this week so I thought I'd take some time to go have a look at the Fisons Fertiliser factory that's been on my lift for awhile with one of my mates. Alas when we got there It was being torn down! We noticed that there was still a small part left that was next to it. I'm not really sure It was even anything to do with it but I thought I might aswell have a look while I'm in the neighbourhood. Here's some pictures of whats left.
