• Landfills
• Incineration
• Source reduction
• Composting
• Recycling

LANDFILLING
• Most municipal solid waste is
deposited in landfills
• Source of groundwater pollution
• Number of municipal landfills is
declining.

• Most fundamental method of reducing waste is to prevent it from being
produced (Waste Prevention).
• Reduce and reuse – Individuals and Industry
• Saves natural resources.
• Reduces waste toxicity
• Reduces costs

COMPOSTING
• Harnessing natural
decomposition to transform
organic material into compost

RECYCLING
• Processing of a waste item into usable forms.
• Benefits of recycling:
-Reduce environmental degradation
-Making money out of waste
• Saving through recycling:
-Making paper from waste saves 50% energy
-Every tons of recycled glass saves energy
equivalent to 100 liters of oil

WHAT CAN YOU DO?
• Buy durable items and repair them
• Buy recycled goods and recycle them
• Buy beverages in refillable containers
• Rechargeable batteries
• Reduce junk mail
• Lobby for trash separation and recycling
• Choose items with minimal packaging & reduce number of bags used
• Compost yard and food waste

IMPACTS OF WASTE IF NOT MANAGED WISELY
• Affects our health
• Affects our socio-economic conditions
• Affects our coastal and marine environment
• Affects our climate
• Rising global temperatures are expected to raise sea levels and change precipitation
and other local climate conditions.
• Changing regional climates could alter forests, crop yields, and water supplies.
• This could also affect human health, animals, and many types of ecosystems.
• Deserts might expand into existing rangelands, and features of some of our national
parks might be permanently altered.
