non-hazardous waste can only been put in landfill, see page 40 for figures.

From the information available, I would not conclude that all non-hazardous waste is disposed of by landfill. Waste of both categories (non-hazardous/hazardous) may be recyclable or non-recyclable.

Compare figures regarding waste on page 70 (slide 37) and the corresponding footnote (13) which states: "... In situations with insufficient guidance from legislation, the definitions of hazardous waste are reported if it is (i) removed from the premises for disposal and/or treatment, or (ii) disposed of on-site (e.g. by landfill). These figures exclude coarse ash from gasification and fly ash from boilers. Non-hazardous waste is waste which requires disposal on a general waste landfill site. Recycled waste is materials left over from manufacturing or consumption, which may be reused or recycled. Hazardous and non-hazardous waste figures have included recycled waste figures since 2013.

This footnote is not really clear to me. They state that "Non-hazardous waste is waste which requires disposal on a general waste landfill site." but also: "Hazardous and non-hazardous waste figures have included recycled waste figures since 2013." I assume they have non-hazardous waste which is recycled and not disposed of by landfill.

I can not clearly determine if total waste - recycled waste = waste to landfill or if it also contains waste which is incinerated (thermal recycling). I would leave this as unknown.

removed value "195,000". Either it is unknown or waste to landfill = total waste - recycled waste = 455,000 tonnes (see page 71 - slide 37). I assume Unknown.
