Study Notes
Types of Agricultural Wastes
- Agricultural solid waste: waste resulting from crop and animal production, processing, and livestock, including manures with at least 20% solids, pruning, and crop residues.
- Agricultural liquid waste: liquid waste and slurry resulting from livestock and poultry production, and crop processing.
Agricultural Waste Management
- A planned system that controls the use of agricultural by-products to sustain or enhance air, water, soil, plant, and animal resources.
Classification of Wastes
Classification by Properties
- Bio-degradable: can be degraded, e.g., paper, wood, fruits.
- Non-biodegradable: cannot be degraded, e.g., plastics, bottles, old machines, cans, Styrofoam containers.
Classification by Effects on Human Health and Environment
- Hazardous wastes: substances with ignitability, corrosivity, reactivity, or toxicity, and are unsafe to use commercially, industrially, agriculturally, or economically.
- Non-hazardous wastes: substances safe to use commercially, industrially, agriculturally, or economically, and do not have hazardous properties.
Classification by Origin and Type
- Municipal Solid wastes: household garbage, construction debris, sanitation residues, packaging materials, and trade refuges, managed by municipalities.
- Bio-medical wastes: solid or liquid wastes from medical diagnosis, treatment, and research activities.
- Industrial wastes: liquid and solid wastes from manufacturing and processing units of various industries.
- Agricultural wastes: biodegradable wastes generated from farming activities.
- Fishery waste: wastes generated from fishery activities, found in coastal and estuarine areas.
- Radioactive wastes: waste containing radioactive materials, often from nuclear processes.
- E-wastes: electronic wastes generated from discarded electrical or electronic devices, may contain contaminants like Pb, Cd, Be, or brominated flame retardants.
Waste Hierarchy
- The Philippine waste management hierarchy prioritizes waste avoidance and reduction, followed by reuse, recycling, and recovery, and finally, disposal.
- The hierarchy's objective is to reduce the amount of materials entering the waste stream.
- Volume reduction strategies include avoidance, product reuse, increased product durability, reduced material use, and decreased consumption.
This quiz covers the types of agricultural waste, including solid and liquid waste, and the management of these waste materials.
