Food waste biorefineries for the production of biofuels, platform chemicals and other bio-based materials can significantly reduce a huge environmental burden and provide sustainable resources for the production of chemicals and materials. This will significantly contribute to the transition of the linear based economy to a more circular economy. A variety of chemicals, biofuels and materials can be produced from food waste by the integrated biorefinery approach. This enhances the bioeconomy and helps toward the design of more green, ecofriendly, and sustainable methods of material productions that contribute to sustainable development goals. The waste biorefinery is a tool to achieve a value-added product that can provide a better utilization of materials and resources while minimizing and/or eliminating environmental impacts. Recently, food waste biorefineries have gained momentum for the production of biofuels, chemicals, and bio-based materials due to the shifting of regulations and policies towards sustainable development. This review attempts to explore the state of the art of food waste biorefinery and the products associated with it.

For a transition to a circular economy to take place, behavioural change from people who are part of the transition is a key requirement. However, this change often does not occur by itself. For systemic behavioural change, policy instruments that incentivise behaviour supporting circular food systems play a key role. These instruments need to be aligned with the environment in which the behaviour takes place. In this study, we scrutinise a case study with five initiatives on the reduction of food loss and waste (FLW) contributing to a circular food system, to understand how specific, well-targeted combinations of instruments as well as other contextual and personal factors can fuel the transition to a circular economy and the reduction of FLW. All the initiatives are taking place under the umbrella of the Dutch initiative “United against food waste” (STV). We use a behavioural change perspective to assess how initiatives that support circular food systems arise and how they can be further supported. Based on the case-study analysis, we arrive at five common success traits and barriers, and five key needs for upscaling. We conclude that motivated, inspiring frontrunners are of key importance in the initial phase of a transition process. However, once a niche initiative is ready to be scaled up, the enabling environment becomes increasingly important.

Renewable carbon feedstocks such as biomass and CO 2 present an important element of future circular economy. Especially biomass as highly functionalized feedstock provides manifold opportunities for the transformation into attractive platform chemicals. However, this change of the resources requires a paradigm shift in refinery design. Fossil feedstocks are processed in gas phase at elevated temperature. In contrast, biorefineries are based on processes in polar solvents at moderate conditions to selectively deoxygenate the polar, often thermally instable and high-boiling molecules. Here, challenges of catalytic deoxygenation, novel strategies for separation and opportunities provided at the interface to biotechnology are discussed in form of showcases. This article is part of a discussion meeting issue ‘Providing sustainable catalytic solutions for a rapidly changing world’.

The article aims to introduce the issue of food waste and all attempts to prevent action. Business and politics are almost interdependent, and any discussion of an economic nature is not complete without a political contribution. The role of politics and politicians in shaping economic activities was and is widely discussed. In the article, there will be a discussion on the problems of food losses and waste in Poland as the member of EU and in India. The idea of the topic came during the tenure of collaboration between representatives of both departments. Conclusions of the study found some similarities and a lot of differences between the countries. Studies have shown that negative attitude of house-hold towards food waste is not frequently reflected in consumers’ behavior, despite their fundamental knowledge on how to reduce food waste. Properly selected and presented information will stimulate both consumer’s attitude and behavior.
