A school in Barcelona manages to reduce food waste to 17 grams per student

Barcelona17 grams per child. This was the amount of food that the students of the Josep Maria de Sagarra school threw in the trash during lunchtime on May 13, when the Criatures went there to get to know the project If I think, I don't throw away first-hand. It is one of the lowest records since the Barcelona school implemented the project in the dining room space, nine courses ago. It did so at the request of Aldara Sarabia, director of the Midday Educational Time at the center, who clearly remembers the moment the project saw the light of day.

It was in the 2017-2018 school year, when the school canteen switched from using trays to plates. The school, Sarabia points out, "made a very important investment in all the necessary material so that the children could serve themselves from I3 to 6th grade." At that time, together with the operational manager of the kitchen company that the center had at the time, the need was detected to go beyond the message of "don't throw away food." "We wanted to create a real and experiential experience so that the children would understand food waste for themselves and be aware of it from daily practice; that's why we launched a project where the children were the protagonists and actively participated in the day-to-day life of the dining room," emphasizes Sarabia.

Self-awareness process

The day we visited them, the teaching staff and Criatures enjoyed a menu consisting of brown rice with tomato, hake with a base of potatoes and orange, the portions of which were served by the students themselves according to how hungry they felt. The ladles available to them – in three sizes, depending on age – mark the minimum amount they should take, but, even so, it is essential that they serve themselves the portion they know they will finish. Maria Pujol, the center's director, emphasizes that the midday space is not separate from the rest of the school,

but rather it is a shared project, where from the methodology to the approach and the treatment given to the children is evident

.

Núria Torres, the school's head of studies, also points out that applying in everyday moments such as lunchtime everything that is dealt with in the theoretical field provides much more significant learning and facilitates the midday space and the learning space being a community.

It is about making them responsible, from I3 to sixth grade, for their actions, from the moment they serve themselves lunch. “There is respect for the students and their feeling of hunger, but they are also given the responsibility to serve themselves an adequate amount, because if they are not hungry and serve themselves too much, the food will end up in the trash,” states Pujol.

This, in Torres's words, “also involves self-knowledge that is not acquired overnight.” The head of studies points out that, within the framework of the project If I think, I don't throw away, not only is food waste being addressed, but also autonomy, self-analysis – how you feel, what you feel like doing, do you like this or that, how did you feel doing this...–. “And if we apply this to basic and physical needs such as feeding oneself, it rounds off and gives meaning to self-discovery,” she adds.

A cross-cutting cultural change

The 2017-2018 academic year, at the Josep Maria de Sagarra School, not only were trays replaced with plates, but the school's management also made a significant investment in glassware and cutlery. Little by little, paper napkins were replaced with cloth ones, as were the picnic bags that students take on excursion days. It has also been advocated that children bring their mid-morning snack in lunchboxes and without packaging, unlike what happened before, when aluminum foil was overused.

These breakfasts, since the school promotes varied, balanced, and seasonal eating, are much healthier, in line with the menus the center offers at lunchtime, where vegetables, fruit, legumes, and protein predominate. “It is a transversal approach, in which all educational agents are involved, from management to teaching staff, including those responsible for and monitors of the midday space, in order to provide coherence and make the project sustainable,” states Núria Torres, head of studies.

The success of the project lies in the involvement sought from the students, who are in charge of setting and clearing the table, correctly separating waste, and finally, weighing the amount of food thrown away each day and keeping a record that is then published both on the school's social networks and in periodic communications and meetings with the students' families. The day Criatures visits the school, we witness how three students from each educational level – who rotate weekly – are in charge of setting the table. Also how they serve themselves food, clear the table and separate waste according to its typology, and how, finally, three sixth-grade students – Bruna, Masha, and Irene – do the weighing. A weighing that today yields one of the best figures of the course: a total of 2.95 kg of food thrown in the trash, which, divided among the 166 students who ate at school that day, makes a total of 17 grams per student.

Continuous improvement as an objective

The project also aims to train skills such as self-awareness, informed decision-making, autonomy, etc., as the child is encouraged to serve themselves by proposing prudent quantities with the option to repeat and to be educated to finish what has been served.

According to Bruna, a sixth-grader and one of those in charge of weighing that day, making a reasonable choice of food when serving oneself "is important to ensure that one eats in a varied and balanced way". As well as to "see how much we throw away and, depending on the data, improve every day". A responsible consumption that she also tries to raise awareness of at home, with the help of her younger brother, who goes to the same school. "We both go together", states Bruna.

Izar is in second grade, has participated in the project since she entered the school, in I3, and, among all the tasks she does each month during lunchtime, her favorite is weighing the leftovers. "I get very happy when there are few leftovers, and I also like everything I learn about food", she explains. In turn, Nahia, from third grade, confesses that what has surprised her the most is that not much food is usually thrown away at school, which makes her happy: "because together we do a good job".

Promote critical thinking in children

Critical thinking in children is also promoted, as, once the records for an entire school year are compiled, emphasis is placed on the social, economic, and environmental implications of this food waste. Last year, the school threw away food worth 1,758 euros. The environmental footprint was equivalent to the emissions of a car traveling approximately 12,000 km, and the water footprint was enough to fill four small swimming pools.

Nahia comments that knowing that with the amount of food wasted at school last year, 24 children could have had two meals for a whole month surprised her a lot, “because it’s a very large amount of food and we need to keep working to reduce the figure”.

All students who use the school's dining service participate in the project, but, as Aldara Sarabia points out, “each stage experiences it differently”. From I3 to third grade, they mainly work on routines and autonomy. “As they grow, they better understand the part of responsibility and environmental awareness, and between fourth and sixth grade, they also participate in recording, weighing, and analyzing the data,” she states. The students in these three grades are responsible for weighing the waste from the two shifts in the dining area and recording the daily data.

As Arabia points out, it is a task “that they do with great responsibility and that helps them see the real impact of what happens every day”. Once the data is collected, they inform the responsible monitor, and the results are communicated via the "walkie”. “Then we calculate the average with all the diners of the day and share it with all the groups during the final circle time, where we talk with the children, reflect on the results, and think together about how we can continue to improve,” Arabia concludes.
