Question

To ask the right hon. Member for Carshalton and Wallington, representing the House of Commons Commission, pursuant to the Answer of 25 January 2018 to Question 122009, how much of the 36.7 per cent of waste which the Parliamentary authorities incinerated at an energy from waste facility was biodegradable.

Parliament’s general waste stream, sent to incineration at an ‘energy from waste’ facility, is not routinely separated onsite or at the facility. Therefore an accurate figure of biodegradable material within this waste stream is unknown.

In November 2015, Parliament commissioned an independent audit of the general waste stream and found that approximately 28% of the sample (by weight) analysed comprised of biodegradable material.
