Waste Management and Sustainability
A.Y. 2023/2024
Learning objectives
Agricultural waste are organic matters which, through clean technology, can be recycled either by integrated waste utilization or simply returned to the place of their origin, nature. Agro wastes can usually be managed to be free of non-natural material, and so they could be appropriately recycled either by physical or biological means.
Clean technology can be implemented to minimize waste, thereby increasing productivity and reducing the unit cost of the product. Successful application of clean technology requires full support from management and full commitment from the clean technology team.

Expected learning outcomes
At the end of the course, students will be able to identify the differences in clean technology propose mitigation strategies to control environmental impact caused by agro wastes, apply appropriate methodologies for the evaluation of sustainable strategies in different scenarios, identify the fundamental principles underpinning modern waste management and work effectively as a member of a multi-disciplinary team

Biomass
Characteristics. The composition of waste material from plants or animals not used for food or feed can be valorized in a circular economy from farming or horticulture, food processing, animal farming, or human waste from sewage plants.
Waste treatments
Aerobic and anaerobic storage techniques, anaerobic digestion, aerobic biological treatment for nitrogen removal.
The principle of the processes, types of plant, and management.
Removal of moisture and stabilization: dehydration and composting. Extraction of mineral fertilizers from the liquid fraction of the slurry.
Composting technologies, industrial-scale composting, aerated static pile composting, vermicomposting, or windrow composting. Phytodepuration.
Resource recovery of organic waste for feed and food application
The use of the organic waste in animal feed, as strategy to reduce the carbon footprint of meat production. Agricultural residues, agro-industrial by-products (co-products, by-products) and food waste material: assessing what organic waste can be recycled into feed. Animal species and specific constraints on the use of organic waste as feed and potential feed safety problems for these species. Recovery of bioactive compounds from vegetable waste as feed additive (e.g. antioxidants, etc), to guarantee animal health. Nutritional consideration and evaluation of agro waste.
Former food. Foodstuffs no longer intended for human consumption and which do not present any health risks when used as feed: use restriction, authorized feed uses, and required treatments,.
Fruit and Vegetable waste. Utilization of fruit and vegetable wastes as livestock feed and for generation of value-added ingredients. Bioconversion of fruit and vegetable waste into terrestrial invertebrates as new feed-food for animals (pet and livestock) and human.
Catering waste, household waste: treatment for pet food.
Processing and transformation. Processes and biotechnologies application enabling efficient and effective recovery systems.
Regulatory and non-regulatory tools: rules for the placing on the market of feed from organic waste recovery.
Risk assessment and safety concerns.
Design new products compliant with the relevant requirements of the feed industry.
