Solid Waste Management
• Waste is collected from most – not all – Households;
• Placed into a pit;
• Burned regularly;
• When one pit full, new pit dug

Challenges of small communities
• Low waste volumes;
• High cost for export;
• Legislating improvements usually not best;
• Motivate the population;
• Extract useful materials: glass, green waste, mechanical devices;
• Keep waste volumes down.

Things to Avoid
• Burning waste: toxic chemicals created, ash is hard to contain;
• Tipping waste into wet areas: run off from waste dump contaminates local water and environment;
• Dumping greenwaste and food into in-organic waste: creates acidic leachates and unstable areas of dump;
• Dumping liquid toxic wastes into dumpsite: acid from old batteries; pesticides, timber treatment chemicals, waste oils.
