Household waste can pose serious health hazards if not properly disposed of. Improper waste disposal can attract disease-spreading flies and rats, release toxic chemicals into soil and water sources, and emit hazardous gases. Preventive measures include proper waste storage, separation, collection and transport, and final disposal through methods like sanitary landfilling, recycling, and energy production. For human waste, options include service or non-service latrines, septic tanks, and sewerage systems to transport waste via underground pipes to treatment sites. Proper waste management is important to prevent contamination and disease transmission.
