Too much waste incineration in North London
The 7-borough North London Waste Authority made what sounded like a reasonable case for burning compostable 'plastic' waste (eg food waste bags) recently but it's burning a lot more than that. So there's a campaign to stop the boroughs automatically investing in a much bigger, replacement incinerator but rethink how this waste is tackled, including much better sorting systems and to prevent any future incinerator from blandly polluting the atmosphere. It looks worth supporting.
