Module Code:AGRI S8017
 
Credits: 7.5
Valid From:Semester 1 - 2016/17 ( September 2016 )
Module Delivered in 1 programme(s)
Module Description:The aims of this module are to provide students with knowledge of the fundamental principles agricultural waste management, with particular emphasis on organic wastes generation, control and alternative options for its future effective management. In addition, an interactive learning environment will be created to encourage students to develop an appreciation of alternative agricultural waste management systems and techniques. This module offers a combination of interactive practical classes, field trips and lectures that will cater for a wide range of cognitive abilities on topics that are highly relevant today, owing to the recent implementation of the Water Framework Directive (2000/60/EC), Nitrates Directive (91/676/EEC), Waste Directive (75/442/EEC) and associated Landfill Directive (99/31/EC) and will be relevant to the future Soil Framework Directive.
Learning Outcomes:
On successful completion of this module the learner should be able to
  1. Compare, contrast and evaluate various agricultural waste classes in terms of their chemical composition and variability.
  2. Identify and synthesise the impact of rainwater harvesting and dirty water control on the efficiency of farmyard management in terms of meeting the requirements of various EU and global legislations.
  3. Develop an appreciation of the fundamental factors that affect soil hydrology, nutrient storage and the movement of nutrients through a soil profile and their possible impact on surface / groundwater contamination.
  4. Critically evaluate the use of natural treatment processes as alternative agricultural waste management options.
  5. Investigate, appraise and constructively criticise complementary and novel waste treatment technologies to effectively deal with apposite quantities of agricultural wastes generated, keeping in accordance with relevant legislations.
  6. Perform lab practicals effectively and efficiently and demonstrate an appreciation of the relationship between the scientific content of the various practicals and their application in the field.
 

Module Content & Assessment

Indicative Content
Agricultural waste classes
Manure storage (farmyard, dairy industries, abattoir, outwintering pads, pig, poultry, mushroom, equine wastes); manure storage capacity; liquid manure; silage effluent; solid manure storage (design and location). Agrichemical wastes; pesticide and herbicide use, control and management; effects on water systems; ecotoxicology. Management, recycling and treatment options for farm plastic, scrap metal, tyres, used oil, oil filters and engine batteries. Implications of various contaminants on climate change.
Natural treatment processes
Integrated constructed wetlands; nutrient control; site assessment; hydraulic resistance times; nutrient cycling, retention and retrieval. Reed bed systems; construction and nutrient retention.
Bioremedation: Principles and applications
Application of agri wastes and biosolids to land and contaminated sites; linking phytoremediation, bioremediation (through plants and bacteria), phytoprotection, carbon sequestration and nutrient cycling. Review of technologies associated with using carbon filters, sand filters and organic wastes as filters in treating various agricultural wastewater streams.
Traditional and conventional waste treatment technologies
Management of diffuse pollution (organic and agrochemical sources) from land spreading (soil hydrology, nutrient storage in soil); buffer strips; fencing; commercial systems, habitat biodiversity recovery; nutrient management planning. Attitudes and public perceptions of traditional and conventional waste treatment technologies.
Innovative waste treatment technologies
Overview of other alternative waste management options (bioenergy). Technologies for slurry separation; decanter centrifuge systems; Options for pelleting liquid wastes. Review of other available commercial systems for treating wastewater e.g. Hydrointernational.
Integrated approach waste management
Inclusion of alternative energy options such as wind, hydro and geothermal energy in waste management. Rainwater harvesting technologies and its impact on the efficiency of farmyard dirty water control. Impacts of agricultural waste management on various legislations including carbon dynamics as addressed under the Kyoto Protocol.
Laboratory practicals
Waste analysis and characterization; Slurry separation using decanter centrifuge systems; In-situ trials on surface run-off using lysimeters; Chemical and biological analysis of integrated constructed wetlands; Composting trials, using Slovita maturity test-kit to determine compost maturity; Phytotoxicity of various wastes using germination index tests.
Field site visits
1. Rainwater harvesting pilot project 2. Integrated constructed wetlands 3. Constructed wetlands at Lakeland Dairies; 4. Local authority reed beed systems; 5. Decanter slurry system / slurry pelleting system.
