Wiltshire Council has granted permission for a chimney at a waste treatment facility to double in height - a move that could eliminate the 'Westbury whiff'.

Hills Waste Solutions asked Wiltshire Council for permission to almost double the height of its chimney stack at the Northacre Mechanical Biological Treatment (MBT) plant in Westbury from 15 metres to 27 metres (88 ft).

The decision was taken under delegated powers meaning that planning officers, rather than county councillors, gave the go-ahead.


The council concluded that the taller chimney might improve air quality and the dispersion of odour - the so-called 'Westbury Whiff'.

They also deemed "the increased stack height would not have a significant impact to the visual amenities of the immediate area, or to the wider surrounding landscape."

Hills pointed out that the neighbouring Arla Dairy building has stacks of 'comparable dimensions'. 

As part of the approval, Wiltshire Council imposed several conditions, including a cap on the amount of waste treated at the facility per year at  90,000 tonnes.

The MBT, which has been operational since 2013, turns waste which would otherwise go to landfill into a 'solid recovered fuel' which is burned to produce heat or electricity.
