Relationship between the amount of liquid coffee produced and daily coffee waste generation in the different restaurants (A-F).
Source publication
Considering coffee's significant social role, reducing coffee waste is pivotal. We quantified liquid coffee waste generated in the Swedish food service sector and explored causes and potential mitigation measures. We combined quantitative data from 76 days across six restaurants with qualitative insights. The results showed that 10% of brewed coffe...

... restaurant A recording the highest median percentage of coffee waste, it produced the lowest volume of coffee (Fig. 2). Its daily coffee production fluctuated between 2 and 130 kg, while its coffee waste varied from 0 to 13 kg. Restaurant D was the largest coffee producer, with daily quantities ranging from 110 to 130 kg, but its waste mass overlapped with that of restaurants E and C, which had brewing volumes of 27 kg to 65 kg, respectively (Fig. 2). ...

Columnar patterns were observed for brewed coffee amount, indicated that coffee is produced in batches. Therefore a day's production is made up of a number of batches, rather than the exact number of cups needed to fulfil customer ...

... Also, the amount of liquid food waste generated across all households is unknown as only 14 students included this fraction in their quantification. Although there are indications that liquid food waste may reach high levels, it is a fraction that is commonly overlooked, highlighting a need to include liquids in food waste quantification (Malefors et al., 2024a;Van Dooren et al., 2019). Major limitations in most food waste studies that try to quantify food waste are bound to occur when there is no set standard of how food waste should be quantified, resulting in difficulties to, for example, compare different studies against each other (Baquero et al., 2023;Withanage et al., 2021;Xue et al., 2017). ...
