Principal recommendations for food waste management improvements in the Hospitality and Food Service sector in Peru and Colombia

Focused in food waste reduction and prevention:

1. Food waste prevention training is needed for staff across HaFS businesses

2. Food waste awareness raising should target both HaFS staff and customers

3. Restaurants should to plan, develop and implement short-term actions and reviews of food waste management practices 

 4. Restaurants need to develop medium and long-term strategies and policies at organisational level to improve food waste management practices as well as systems

5. Governments and a range of stakeholders included restaurants and suppliers need to develop strategies and policies for food waste management at local and national level

Going beyond food waste management:

1. An integrated approach to sustainable development is needed to improve waste management systems. This includes stakeholder engagement, participation, partnership and collaboration.

2. Environmental management system implementation and continuous development is required to improve waste management as well and other environmental, economic and societal aspects at organisational, local and national level. In addition, environmental management systems could help improve the overall management of restaurants, especially small and medium enterprises which has been the case in other studies.

3. Explore possibilities of developing business models and brands that have environmental and social concerns and related actions as a central aspect.

In addition to a literature review, we generated primary data from three main stages of the project. These encompassed an online quantitative survey, a series of qualitative expert interviews and an online workshop for HaFS representatives in Medellín. The latter involved a mixed grouping of participants with contributions from HaFS business representatives, academics and, specialists in food waste reduction and the circular economy.
