Fuente: Broccoli Byproducts Extraction Due to the increasing global population, the need for nutrition is growing and diversifying. To achieve this, global demand for agricultural production is increasing. This leads to rapid consumption of limited resources, increased greenhouse gas emissions and significant food waste, all of which negatively affect the environment. This section discusses innovative approaches to improve the sustainabilitySustainability of agricultural production and current strategies for managing food and agricultural wasteAgricultural waste. The techniques emphasised aim to achieve sustainable agrarian output by integrating the principles of waste management with the concepts of the circular economyCircular Economy (CE) and regenerative agriculture. One of the main goals of approaches such as precision agriculture practices, biorecycling of valuable waste and residues after harvest, product production and compostingComposting is to minimise crop loss. These technologies focus on soil and water health, energy recovery, and nutrient recycling, which are critical components of environmentally friendly and sustainable agri-food systems. Policy frameworks, local governments, social awareness, stakeholder engagement and innovative business models are essential considerations for transitioning to agriculture and food processing systems that produce less waste and pollution. This section includes prominent engineering technologies to increase the sustainabilitySustainability of agriculture and food systems in the near future, current research and examples from international studies to provide pragmatic concepts. This chapter aligns with the Sustainable DevelopmentSustainable development GoalsSustainable Development Goals (SDGs) (SDGs) 2, 3, 6, 7, 8, 9, 11, 12, 13, and 15.
