Abstract
Taking into consideration the circular economy context, from cereal production and processing result by-products and residues which can be transformed into the new raw materials. Straw, husks, brans, flours, bread waste, confectionary waste, so on, can be re-used using different processes such as: extraction, fermentation, microorganism cultivation, for obtaining added value products. These new products obtained can be: biofuels, enzymes, biodegradable material food contact, single cell protein, bio-adsorbent, nanoparticles, bio alcohol, bioactive compounds like fibres, phytochemicals, minerals, so on. This paper is a short review regarding sharing knowledge and good practices in implementing circular economy within food systems, specifically, cereal supply chain.
Highlights
Cereal production and processing are one of the most important sectors of agri-food industry knowing that the cereal food products cover over 20% of daily diet [30]
The cereal supply chain waste estimates show that, for example, wheat straw is produced in SUA in amount of 57,000 tonnes/year [34], rice husk in amount of 120,000 tonnes/year at the global level [14] and cereal waste, in general, in amount of 40,00045,000 tonnes/year in Europe [8]
Many favourable outcomes, coming from the recent literature showed that researches on different cereal waste, such as straw and bran, rich in simple sugars and complex carbohydrates have been demonstrated generation capacity of bio-fuel producing of such substrates
Summary
Cereal production and processing are one of the most important sectors of agri-food industry knowing that the cereal food products cover over 20% of daily diet [30]. One of the aims of waste management in agri-food industry is to improve resource efficiency while protecting the environment. For this purpose, management strategies and measures for the proper reduce waste or transform it into new raw materials are needed. Management strategies and measures for the proper reduce waste or transform it into new raw materials are needed These management strategies are included within the circular economy system which is an industrial system that is regenerative or restorative by intention and design Different studies for the management of food waste along the supply chain offer opportunities to biofuels, biodegradable plastics, alcohols, enzymes and nanoparticles production, so on, among many others [24]
