Mr Stevenson said: "Christmas is traditionally a time when people celebrate and eat well but at a time of excess, it is worth stopping to think about what happens when we waste food and drink. Households who are spending more than they need to on food are facing an unneeded financial drain on their resources.
"The cost of wasting food and drink quickly adds up and costs every household in Scotland an average of £430 a year. That is completely unnecessary and is money that people can ill afford during these difficult financial times, so it is essential that local authorities do all they can to assist people in reducing food waste.
"The fact that 17 of Scotland's local authorities are now collecting food waste separately is a significant step forward and that is only set to grow substantially as at least a further seven councils will offer these services next year.
"Some excellent progress has been achieved so far but we all have a responsibility to do more if we are to reduce food waste down to a sustainable level."
