The document discusses the concept of zero waste, highlighting various sources of waste including household items, plastics, and electronic waste, and the environmental hazards associated with landfills. It details how toxins from waste can leach into the environment and the significant impact of methane emissions on climate change. It advocates for practices such as reducing, reusing, recycling, and composting to minimize waste and protect natural resources.

3. LANDFILL:
 A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or
dumping ground, is a site for the disposal of waste materials. Landfill is the
oldest and most common form of waste disposal.

4. WHAT IS THE PROBLEM WITH LANDFILLS:
 Toxins
Many materials that end up as waste contain toxic substances. Over time, these toxins leach into our soil
and groundwater, and become environmental hazards for years. Electronic waste is a good example.
Waste such as televisions, computers and other electronic appliances contain a long list of hazardous
substances, including mercury, arsenic, cadmium, PVC, solvents, acids and lead.
 Leachate
Leachate is the liquid formed when waste breaks down in the landfill and water filters through that waste.
This liquid is highly toxic and can pollute the land, ground water and water ways.
 Greenhouse gas
When organic material such as food scraps and green waste is put in landfill, it is generally compacted
down and covered. This removes the oxygen and causes it to break down in an anaerobic process.
Eventually this releases methane, a greenhouse gas that is 25 times more potent than carbon dioxide.
The implications for global warming and climate change are enormous. Methane is also a flammable gas
that can become dangerous if allowed to build up in concentration. Composting your food scraps and
green waste in a compost bin eliminates many of these problems.
Apart from the financial costs, garbage buried in landfill breaks down at a very slow rate and remains a
problem for future generations.

6. What is Zero Waste?
 Making sure that you keep materials within the
economic system
Using less, re-using, recycling, composting
 Avoiding – phasing out – residual waste
 The material that isn’t reused, recycled, composted
(that isn’t kept ‘in the loop’)
 Residual waste is a problem whether it is
incinerated or landfilled
 Reducing our use of natural resources
