livestock mechanisation and manure management 2: manure management
Code: G5812D
Teacher:  Giorgio Mario Provolo
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 3
Practices in classroom: 1
Basic aims:  To understand that the use of machinery in livestock husbandry is necessary for the environment and for socio-economic reasons. To understand how machines work, their performances and limits while taking into account health and safety regulations. To learn how to choose machinery and installations. To learn how to plan and design structures and plants in relation to the problems of agricultural waste management. Special reference to livestock waste management in relation to environment safeguard will be done.
Acquired skills:  Students successfully completing the program will be able to: choose and define the most suitable forage harvesting and cattle feeding mechanization chain; design and control milking plants, renewable energy supplies and implement health and safety regulations for machinery and installations. In addition they will know functional and design criteria of structures and plants for agricultural waste management and they will be able to use simulation and calculation tools to support the correct management of agricultural waste, with special focus on animal manure, for environment safeguard.
Course contents:  Characteristics and management of agricultural wastes. Design of removal and storage systems of effluents in relation to environmental impact risk. Selection criteria of the management system of the effluents as a function of the relation of the agricultural settlement and the surrounding area. Agronomic use of animal manure. Main waste treatment plants (chemical, physical, biological). Aerobic and anaerobic treatments. Phyto-remediation.
Program:  Waste characteristics and legal constraints. Characteristics and management solutions of agricultural wastes. Standard and legislation main points. Design of removal and storage systems of effluents in relation to environmental impact risk. Agronomic utilisation of agricultural wastes. Selection criteria of the management system of the effluents as a function of the relation of the agricultural settlement and the surrounding area. Agronomic use of animal manure. Compilation of the Manure Management Plan. Main waste treatment plants (chemical, physical, biological). Aerobic and anaerobic treatments. Structuress and plant for waste treatment: separators; decanters; aereation basins; digestors; filters. Energy production by using anaerobic plants. Desing of anaerobic and anaerobic with biomas recirculation plants. Waste management in relation to farm and environmental demands. Phyto-remediation plants. Transport and spreading of wastes. Selection criteria of different waste management systems in relation to plant design option.
Prerequisites:  The knowledge of agricultural system and of livestock farm management, is useful.
Preparatory instructions:  Mathematic, Physic, Farm Structures
Learning materials:  1. Notes of the lessons (ariel.ctu.unimi.it - Costruzioni rurali) 2. Manuale di Agricoltura - HOEPLI 3. G. Provolo - Gestione dei reflui zootecnici - Point Veterinaire Italie, 2008. 4. Qauderno della Ricerca n. 93 - Regione Lombardia 5. Papers and documents available on the web site ariel.ctu.unimi.it - Costruzioni rurali
Other info:  The final exam is based on a project work where the selection and design criteria related to the waste management are applied to practical farms. The examination will be based on the discussion of the project work through which the knowledge of the design tools examined during the course will be checked.
