The North-east has been dealt a double jobs blow, with almost 120 posts at risk.
Muller Milk & Ingredients has confirmed 89 positions are under consultation at its Aberdeen dairy along with a further nine at its city depot.
Energy firm SSE has also announced plans to shut all of its stores across Scotland, with the loss of 20 North-east jobs.
Muller is proposing to invest £15 million over the next three years in its Bellshill dairy, but its North-east branch is one of two which could close due to being inefficient.
A 45-day statutory consultation is to take place on the proposals, with a further 131 roles in the balance in East Kilbride.
The company said North-east farmers wishing to supply milk to the Bellshill operation would be charged an extra 1.75 pence per litre of milk, and those who do not wish to continue to supply will have their contracts terminated after 12 months’ notice.
Andrew McInnes, managing director of Muller Milk & Ingredients, said: “It is important to stress that the status quo is just not viable in the medium term.
“Our Scottish dairies are inefficient and costly which is putting a brake on the innovation and investment needed to stimulate new demand for dairy products.
“Our Aberdeen dairy is operating at less than 40% of its capacity and milk production from farmers in the North-east is far in excess of customer requirements in the area.
“We will enter the consultation with an open mind and will rigorously assess the situation and listen to our colleagues before arriving at a decision.”
Under SSE’s closure plans 119 employees from 37 stores – including Aberdeen, Banchory, Banff, Buckie, Brechin, Huntly, Inverurie, Peterhead and Stonehaven – and its online shop would be affected.
SSE director of domestic retail Stephen Forbes said: “We know some of these shops have been on local high streets for a long time so we did not take this decision lightly but footfall and sales have reduced considerably and there is, unfortunately, no realistic prospect of that long-term trend reversing.
“Our priority is to ensure our colleagues are fully supported during this time and we will work to redeploy staff within the SSE group where possible.”
