If you do not waste food you will never go hungry – so the old saying ‘waste not, want not’ leads us believe. To many, this phrase conjures up images of queues outside grocers of wartime Britain and a by-gone era of thrift. While the phrase may feel out-dated, the philosophy of reducing waste is more relevant than ever and has been re-invigorated by a growing sustainability agenda. Meanwhile food waste continues to present problems worldwide; one-third of all produce in the world is not actually eaten according to the Food and Agriculture Organisation (UN) and, shockingly, almost half is thrown away in the UK.
Bringing it a bit closer to home we can look at how much we waste in St Andrews. As a University we produce over 150 tonnes of food waste each year, and whilst this figure has been falling there is clearly more we can do. To find out more, I spoke to Alan Riddell, Catering Manager for the halls of residences across the University. He tells me the on-going challenges faced in increasing the choices for over 2,000 students: “It’s a delicate balance but we’re trying to reduce waste, improve our menus and provide good value for money.”
With these aims in mind, Mr Riddell talks through the process of how these meals are made: “Firstly all portion sizes are standardised throughout halls, but it proves difficult to always accurately predict how much food to cook on a day-to-day basis.” The difficulty lies in the fact there is not a tried and tested method to understand why meals are popular; often, unpredictable factors such as the weather, the previous nights’ activites and events or even peoples’ timetables make planning impossible. Inevitably this can lead to an increased amount of food waste, but there are steps that are being taken to tackle this, such as providing second helpings for students and staff after each meal.
Simple behavioural changes can also help to reduce waste, as Mr Riddell highlights when talking about vegetable and salad servings, which anyone can help themselves to. He says: “We want to encourage students to eat everything they put on their plates in the first place and to go for second helpings rather than taking larger portions which aren’t eaten and have to be disposed of.” At the University of Manchester they tackled this issue by requiring students to clear their own plates into food recycling bins to make it more obvious how much was being thrown away and to shift responsibility.
Here in St Andrews Transition have been running the CookSMARTER (Save Money and Reduce Time Energy and Resources) programme to provide training for sustainable and healthy cooking around catered halls to help change behaviours whilst also helping to improve recycling facilities with the roll-out of food waste caddies to residents in self-catered halls, including Albany Park.
Back in catered halls, Mr Riddell reminds me that the catering team are open to engaging with new ideas. For this semester’s Green Week extra vegetarian options were offered to provide more choice whilst considering the carbon footprint of the meal, in response the suggestions from various students. This setup is currently being reviewed to ensure that food waste does not increase as a result of greater menu choice and that the new menu is popular. But it shows that these issues are taken seriously.
Furthermore, it is becoming harder to throw away food waste to landfill, which makes the case for food waste reduction even stronger. In January 2014 the Scottish Government introduced legislation affecting all large businesses and organisations that requires them to dispose of their food waste separately from landfill. Alongside the University’s aims to send zero waste to landfill by 2020 as part of its sustainable development strategy, nearly all of the food waste from the University is transported to an anaerobic digester 25 miles away at Glenfarg (Perthshire) where it is converted into electricity.
Whilst this is a clever solution, it is clear that we need to reduce the amount of food wasted in the first instance; our current practices are unsustainable. There are simple things we can all do, such as more considerate meal planning, to foster a culture of ‘waste not’ into the future.
