Abstract
With the world population set to approach an estimated 9 billion by 2050, against a background of finite natural resources, we need renewable biological resources for securing healthy food and animal feed to meet the nutritional requirements of the growing population. In this paper, key findings from ReValue Eranet project financed by Norway, India, and Spain are presented. The project aims to contribute to the UN Sustainable Development Goals (SDG) target on food losses reduction, by developing innovative technologies for the surimi industry, namely reducing losses by improved cold chain management and efficient conversion of rest raw materials (RRM) and wash water into value-added protein and oil ingredients for food and feed applications. A multidisciplinary research approach was applied with expertise from supply chain management, life cycle assessment, biotechnology, energy, and process engineering to propose several solutions for improving the overall resource efficiency of the surimi supply chains in India. This paper presents a synthesis of proposed solutions from ReValue project and potential contribution towards SDGs as well as market exploitation strategies.
Highlights
Bioeconomy and circular economy concepts have gained significant interest in recent years
The bio-economy business model is directed to sustainable production via the conversion of natural biomass and by-products into a range of food, health, and other industrial products
The impact of the surimi industry on global food waste production, responsible for more than 3.5% of the global fish losses, is due to its low efficiency processing that generates a huge amount of rest raw materials (RRM) and wash water
Summary
Bioeconomy and circular economy concepts have gained significant interest in recent years. Circular economy concept replaces the linear production model of “take, make and dispose” with a circular model in which the waste is kept within the system and reduced, recycled, and remanufactured [1]. Improving resource efficiency is one of the key features of bioeconomy which is defined by the European Commission as using the earth’s limited resources in a sustainable manner while minimising the impacts on the environment. Improving resource utilisation efficiency is an important approach to reduce environmental impacts and increase economic performance simultaneously [2]. A transition towards a circular economy provides a way to improve resource efficiency of the food system. The EU Waste Framework Directive (WFD) [3] sets the basic concepts and definitions related to waste management, including definitions of waste, recycling, and recovery.
