Abstract
The need for innovative approaches to tackle food waste problem is widely recognized, given its tight links with agriculture, food security, trade, energy, deforestation, and climate change challenges. As a matter of fact, an emerging branch of literature is drawing attention to the value of food waste, reporting both technological aspects of food waste valorisation (by means of case studies and/or pilot-scale laboratory experiences), and how such innovative pathways may contribute to the transition towards sustainable production and consumption systems and a more sustainable waste regime. However, little research efforts have been invested so far in relation to the development and diffusion of innovative approaches addressing the food waste problem and the role of grassroots innovations. Thus, our chapter aims at contributing to this strand of literature, by addressing two main issues: how do grassroots movements act and how effective are they in catalysing innovation in the food waste field? what are the specific roles that grassroots innovations may play in the transition towards sustainable production and consumption systems and a more sustainable waste regime?
