Hazardous waste entering disposal facilities
This data contains figures for the amount of waste entering city disposal facilities.
This is listed as "Special waste" in the dataset, which is labelled as "Special waste: Hazardous waste requiring a permit for disposal purposes."
This dataset combines two files: the Jan 2011-April 2015 waste disposal dataset, and the Jan 2015-Jan 2018 dataset. The former dataset is more detailed (waste is broken down into more categories), so for the overlapping period (Jan-Apr 2015) data from the first dataset was used. The figures were similar but for some months these numbers were not exactly the same.
The data can be downloaded from the Open Data Portal. No further calculations are required, but the information is formatted in a table format that requires a bit of moving around to get it all in single rows.
