wallpaper paste...disposal query

[Richard Caville]

This has no doubt been asked before, but what is environmental way to dispose of leftover wallpaper paste?
Ive just used B& Q Diall packet (not pre mixed) and it doesnt give advice. (Thanks BQ!) I now live in a rural area....but when in city suburbs I used to dilute and put directly into drain, so now have septic tank and dont even want to put down any other drain as it will go into watercourses.
Do they all have fungicide in? Does paste actually harden if left? then I can put in black bin bag.
Thanks for tips.

I'd just leave it to thicken/harden in the bucket or an untied bag and then throw it away with the household rubbish.

If you leave it in the bucket, it'll go down to pretty much nothing, but might be hard to clean out complexly. Poring it into the untied bag in a bucket and letting it dry out is the best bet, then put it in the household rubbish.

Don't leave it in the bucket, it absolutely stinks to high heaven. Pour into a bin bag and chuck it in your wheelie bin. Bucket can be washed out with warm water.

This form of paste isn't harmful to the envionment so I wouldn't worry about it too much. Dilute it to as thin as possible and you can dispose of it by throwing it into a corner of your garden. You could also do the same into your septic system, but there is always a miniscule chance of some drying out and causing a blockage.(Far less than a funky turd! )
Obviously, some people will frown upon it going into the ground, but it really isn't an issue.
One of the bigger manufacturers (Solvite, Polycell, etc) should have an online pdf which will show it isn't harmful, but no doubt will contradict themselves (to cover their backs) by stating you should take it to your recycling centre.
Also, as dcdec says, it will stink after a while if you leave it stand but will also turn watery.

In my experience, the paste used to thicken and eventually just become a thick skin.

Now I find that the water rises to the top and the "starch" drops to the bottom. As mentioned by DcDec, it will end up being very smelly and you often get mold building up.

I pour it down the bog... Or I dig a little hole in the garden and dispose of it there.

I can only assume that they have reduced the fungicidal content over the years.
