Green energy firms highlighted at Royal Highland Show
Scottish food and drink firms who power their business through renewable energy will be featured at this year's Royal Highland Show.
The "Made in Scotland from Renewables" highlights companies who use green energy to produce their products.
Organisers said the 12 firms show the benefits in investing in renewable energy.
The food and drink industry is expected to be worth £16.5bn to the Scottish economy by 2017.
All of the companies featured in the "clean dozen" are using are using a range of technologies, including wind power, solar energy, biomass and hydro.
The list of suitable companies was drawn up by East Coast Renewables, a group of five Scottish local authorities - Aberdeenshire, Angus, Fife, Perth & Kinross and East Lothian councils.
Niall Stuart, Chief Executive of Scottish Renewables, said: "This is a great initiative involving two modern-day Scottish success stories - renewable energy and the food and drink sector.
"I am delighted an increasing number of companies in this fast-growing sector recognise the tremendous economic and environmental benefits from powering their businesses using renewable energy."
He added: "We are finding that businesses using renewable technologies on site are getting payback on their investment in just a few short years, meaning they are saving money in the long run."
Mr Stuart added: "There are four persuasive reasons why these food businesses are moving to renewable generation; to lower their energy costs in the future, to reduce their carbon footprint, to potentially generate income - and because consumers are increasingly conscious of the environmental credentials of everything they buy."
Mackie's was one of the early adopters of wind power and the firm's finance director Gerry Stephens said: "Making ice cream uses a lot of energy, so we set out to make up for that by using renewables - and we have become one of the greenest companies in the UK."
The company, based in Rothienorman, Aberdeenshire, has three wind turbines as well as solar panels installed on the roofs of it's farm buildings.
It has also recently been granted permission for the creation of a solar farm which will produce 1.8 megawatts of power.
Mr Stephens said the switch to renewables had reaped massive energy savings: "We have a very good, windy site and high efficiency levels. Our power bill without renewable energy would be around £500,000 and we are actually paying about £150,000."
The Royal Highland Show takes place on 19-22 June at the Royal Highland Showground at Ingliston, near Edinburgh.
