  1. Solid Waste Management in Emergency Solid Waste Management Cycle Technical option in emergency Environmental implications

  2. Solid Waste – Sphere project People have an environment that is acceptably uncontaminated by solid waste, including medical waste, and have the means to dispose of their domestic waste conveniently and effectively.

  3. Identify waste type Waste source Determine potential hazard Determine volume Determine collection/storage methods & transportation method Determine disposal method Solid Waste management cycle Organic waste, paper, cans, bottles, plastic packaging, dead animals, oil, chemicals, medical, concrete, stones, etc. Households, Aid Agencies, Communal areas (markets), Industries, Medical facilities Faecal contamination, Flies, rats, cockroaches, chemical contamination, Fire risk, etc. 1 person / 0,5-1 liter of refuse / day organic content of 25-35 %. Household containers, Small collective containers, Waste collection depots Burning, Burying, Composting.

  4. Storage methods Storage: Household containers Communal bins Old oil drums Fenced – in areas.

  5. Transport methods • Human powered: open hand cart, hand cart with bins, wheelbarrow, tricycle. • Animal powered: donkey drawn cart • Motorized: tractor, trailer, truck.

  6. Waste disposal methods in emergency • Disposal pit • Landfill • Burning Limiting factors: Soil conditions Groundwater level Type of waste source Topography Quantity of wastewater production

  10. Landfill: some considerations Poor design or poor management of landfill sites can lead to: • Groundwater and surface water contamination (result of rain percolating through the waste and reacting with the products of decomposition) • Attraction of vermin (mice and rats) • Air pollution and greenhouse gas emissions – methane and carbon dioxide (produced as organic waste breaks down anaerobically). • Malodours, noise, dust, etc.

  11. Safe disposal methods: Burning • Burning can reduce the volume of trash by 80 to 90 percent. • The temperature in a burn barrel rarely exceeds 500 degrees Fahrenheit. The temperature is not hot enough for complete combustion of the materials in the barrel.

  12. Burning: some considerations • Pollutants from combustion are emitted into the environment affecting air quality and health. • Ash (particulates) can irritate the eyes and throat and can restrict visibility. • The ash resulted from the burning process is considered a highly toxic waste product. This must be carefully handled and buried. • PVC plastic (present in most of packaging items) is the major source of dioxins. • Visit www.burnbarrel.org
