Food waste case study and monitoring developing in Finnish food services.

For enhancing food waste weighing measurements we established a platform (Restaurant Forum RF) for different kinds of food service businesses. Our aim was to explore food waste data, but also to develop a monitoring system by increasing our knowledge about the relevant processes and possible internal barriers. We studied food waste generation and origin in the outlets and how to avoid overproduction of food and buffet line waste. During 2016-2017, a number of outlets (n = 51) conducted food waste measurements over a period of two weeks. The businesses that participated included schools, day-care centres and work place and student canteens, which present sectors that mainly serve a lunch buffet. According to our results, 17.5% of all prepared food ended up as waste, which can be further divided into kitchen waste (2.2%), serving waste (11.3%) and customer leftovers (3.9%). On average, 449 g of food was prepared per portion and 78 g of this ended up as waste. We also studied the mechanisms of waste generation, best practices for decreasing food waste, how staff experienced weighing measurements and how measurement systems can be utilized in food service business management.

Elements affecting food waste in the food service sector.

Avoidable food waste is produced in the food service sector, with significant ecological and economical impacts. In order to understand and explain better the complex issue of food waste a qualitative study was conducted on the reasons for its generation in restaurants and catering businesses. Research data were collected during three participatory workshops for personnel from three different catering sector companies in Finland. Based on synthesized qualitative content analysis, eight elements influencing production and reduction of food waste were identified. Results revealed the diversity of managing food waste in the food service sector and how a holistic approach is required to prevent and reduce it. It is crucial to understand that food waste is manageable and should be an integral component of the management system. The model of eight factors provides a framework for recognition and management of food waste in the food service sector.

Food waste volume and origin: Case studies in the Finnish food service sector.

We carried out a project to map the volume and composition of food waste in the Finnish food service sector. The amount, type and origin of avoidable food waste were investigated in 51 food service outlets, including schools, day-care centres, workplace canteens, petrol stations, restaurants and diners. Food service outlet personnel kept diaries and weighed the food produced and wasted during a one-week or one-day period. For weighing and sorting, the food waste was divided into two categories: originally edible (OE) food waste was separated from originally inedible (OIE) waste, such as vegetable peelings, bones and coffee grounds. In addition, food waste (OE) was divided into three categories in accordance with its origins: kitchen waste, service waste and customer leftovers. According to the results, about 20% of all food handled and prepared in the sector was wasted. The findings also suggest that the main drivers of wasted food are buffet services and overproduction.
