Leftover plaster powder
Guidance
Alias
plasterboard
If you have leftover plaster powder, you could try offering it for free on a community forum (opens in a new window).
If you can't find a way to reuse it, you can put it in the 'plasterboard' container at one of north London's reuse and recycling centres. It must be separated from other waste as it contains gypsum so please make sure you follow this guidance.
Alternatively, you could enquire with your local council whether they accept plaster powder as part of their large item (bulky) waste collection service.
