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.

No one has the slightest doubt about the enormous potential that the African continent has as a tourist destination. The diversity of cultures, the great biodiversity that it possesses, the multiple artistic manifestations that it offers and the beauty of the seas that surround it are key pieces in continuing to promote its capacity as a tourist attraction, which is approximately 60 million tourists per year who generate seven percent of exports and employment. However, in order for Africa to take off, it is necessary that a number of conditions related to security, health, education, eradication of poverty, reduction of inequalities, peace and justice and quality of its waters, among others, are intimately related to the Sustainable Development Goals defined in the 2030 Agenda. In this context, we maintain that the implementation of the Circular Economy in Africa will be a key tool in this process of improving the sustainability of this continent in its three aspects, economic, social and environmental, and raising its level of tourism competitiveness.

The research represents the analysis of the circular economy and its essential characteristics of circular economy in the modern world. The circular economy makes it possible to "detach" the country's GDP growth from the consumption of natural resources and environmental pollution. It explains how the circular economy should stimulate sustainable development and inclusion in the system of Sustainable Development Goals. The research presents how the circular economy can ensure labor productivity, efficient environmental and energy conservation, and the creation of new jobs. It analyzes principles and tools of the circular economy. This research shows how economies should move from the current linear take, make, use, dispose practice to reuse and longer product life. It shows how current business models change and what principles are used to develop a circular economy. It examines the circular approaches based on the 3-R principle: Reduce: reduce resource use and prioritize renewable materials; Reuse: make the most of the products; Recycle: recover by-products and waste for further use in the economy. The research shows how seven key tools of the circular economy may be applied. It reveals the international experience in implementing the circular economy principles. The research describes the benefits that the transition to a circular economy brings. It analyses major circular economy barriers, such as financial, social, and technical. The research distinguishes the benefits of a circular economy. They include a decrease in costs, a cleaner and safer environment, sensitive use of natural resources, new job creation, reducing dependence on imports. This research presents the examples of Norrköping Industrial Symbiosis Network in Sweden, Latvia’s circularity business models.
