Data can be found on p.18 of their Global Reporting Initiative Nov 2015 report. Data was provided in MT.

The company reports "Total 433.5 MT of waste disposed in 2014". It is unclear if this is supposed to be the total for nonhazardous, or the total including hazardous waste. They report hazardous waste on page 19 as 722 tonnes. This makes MT look like it could mean mega tonnes, but it does not seem possible that the company could have generated almost 434 million tonnes of waste. The most likely interpretation is that 433.54 tonnes equals the companys nonhazardous waste.
