The NHS goes through millions of single-use hot drinks cups each year. In practice, these cups are not recyclable and are ultimately sent to landfills or incinerated. To reduce the environmental impact of single-use cups, the University Hospital Crosshouse in Ayrshire partnered with Zero Waste Scotland to trial recyclable single-use and re-usable cups alongside a suite of measures to encourage re-usable cup usage among the hospital’s ~5,000 staff. The trial was supported by cup manufacturers REACH and Amaray, and raw material producer Borealis.
