Don't they sort landfill to a certain extent , remove batteries, electricals ect ,i keep seeing these jobs where they stand over a big conveyer belt
when you take a black bag to some tips in Cornwall they have a policy to go through it at their discretion, to check for recyclables mixed in
Not generally.
IIRC The jobs for sorters are for the likes of the "recycling" bins where they might employee people to assist in sorting the materials at the recycling facility.
The black bag checks are I suspect much more random and to basically point out "you numpty that goes in the paper bin over there" sort of thing, my local council has a policy that if the bin collectors see the wrong sort of stuff for the bin it's in they can refuse to empty it and will leave a note for you, and the local tidy tip has staff who will point you to the right container if you've got any queries.
What's the basis for that claim? He's got a set of investors putting up the funds for this, it's not him funding it, their proposal is to process on a part of the site I thought, it's not like it's a load of rubbish being taken away and then a risk of the operation stopping.
Except that that is still a risk the council will have unless they get a very hefty upfront payment that is a lot more than they expect it to cost.
That still doesn't help with the disruption to the tip that it is going to cause as tips are not generally laid out in a way that makes it easy to cordon off an area, and any search as I said before is going to require them digging up a far larger area than the initial "this is where we were dumping on the day", then have at least the same sort of area or more again set aside to shift the rubbish into, and that rubbish is going to have to be hand sorted and go down a fair bit further than the expected layer for the week or month of the dumping. Bear in mind that tips don't just throw the rubbish down and forget about it, they tend to have the likes of bulldozers compacting it and levelling it, which means anything put down in one specific area could be moved around a fair bit, or potentially disturbed and lifted weeks or months later and moved again.
You're looking, depending on the size of the area the tip was covering potentially hundreds of thousands of tons of waste to be moved and sifted by hand, this is not going to be cheap, quick, or done without massive disruption to the site, and the health and safety and insurance issues for it are going to be pretty big and the council probably can't just get away with getting a lawyer to write up a document saying "I the undersigned absolve the council of any responsibility for anything that happens" as it tends not to work like that.
I mean I can see one possible way it could be done, they buy the tip site when it's closed down, but even then there are going to be a bunch of legal, environmental and safety issues involved that mean the council would likely have to shut down the hunt.
