Course description

Introduction to waste management and its relevance to agriculture, natural sources, animals and humans. Type of agricultural waste, amount and volume. Agricultural waste associated with animals: manure, bedding and litter, wasted feed and wastewater from buildings. Impact of nitrates which are commonly associated with fertilizers and agricultural waste runoff. Impact on groundwater’s. Legislation and regulations of EU and Republic of Croatia for waste management in agriculture. Reduce, reuse and recycle, the three R’s, for waste management, like effective measures that serve as alternatives to disposing waste in landfills. Best management practices (BMPs) such rotational grazing and pasture renovation. Description of modern landfill. Incineration. Mechanical biological treatment of agricultural waste. Composting. Handling of manure, food-processing waste, sewage sludge. Waste water and disposal of waste water by irrigation. Hazardous waste in agriculture: pesticides, herbicides and different agrochemicals. Packaging waste and its management. Environmental impact of traditional agriculture and farming on water, soil and air. Sustainable development and agriculture.
