Aim: To learn practical ways of recycling so that we can make our world a better place.
How can we prevent climate change through recycling these products?
Plastics: Recycling plastic prevents burning it which produces C02.
Cycling or walking: We don't use fossil-fueled vehicles that emit C02.
Plastics: Recycling plastic prevents burning it which produces C02.
Cycling or walking: We don't use fossil-fueled vehicles that emit C02.
Paper: Recycling paper helps us to sustain trees that we use to change C02 to Oxygen.
Steel: When we recycle steel we don't use as much coal [C02].
Steel: When we recycle steel we don't use as much coal [C02].
Video questions:
What is Zero Waste?
One of the quickest and cheapest ways a community can immediately reduce climate impact.
What can we do on the planet?
What can we do on the planet?
- Reduce the use of disposable material, disposable cups; Use more Reusable materials, using your own bags to shop, etc.
- Repairing broken produces and sharing products rather than buying each individualy.
- Recycle what we can, like steel, plastic, paper and other recyclable materials
- Put biodegradable materials compost disposal instead of other types of rubbish bins; or our soil, as it takes the most C02 off our atmosphere.
What do we need to recycle?
Anything that we can, plastic bags, plastic in general, steel, etc.
What does recycling do?
It prevents more damage to the planet as it does not use as much fossil fuels
How much of our rubbish is food scraps?
In New Zealand, we produce about 157,389 tonnes of food a year.
What does soil do to carbon dioxide in the atmosphere?
Soil absorbs about 3 times more than the trees and the atmosphere
What do we need to do?
- Make Changes.
- Have Zero Waste
What is a carbon footprint?
Carbon footprint is the amount of carbon dioxide and greenhouses gases.
How can you make your Carbon Footprint smaller?
Use other energy methods, hydropower, solar power and any other non-fossil-fueled energy. Walk, cycle, instead of using fossil-fueled vehicles or mechanisms.
ENERGY SAVING TIPS FILM
Name 4 of the tips.
- Use, less electricity, turn off appliances when not needed.
- Put biodegradable materials in the soil or in the compost.
- Try to recycle more objects or use recycled materials.
- Reduce the amount of processed food that is consumed.
AT WHAT RATES DO DIFFERENT ITEMS DECOMPOSE?
MY INVESTIGATION.
Choose 5 items from the list and investigate them.
Paper
Plastic bag
Aluminium can
Leaves
Styrofoam
You need to answer three questions.
Name: Paper
- How long do they take to decompose? Around two to six weeks.
- What resource/fossil fuel are they made from? They are made out of wood pulp and vegetable (Cellulose0 fibres.
- How is this resource recycled? The paper is brought to a recycling plant, washed so that the ink or whatever materials that are in it is taken out; then made into cardboard, office paper, etc.
- How does this object contribute to climate change? Production of recycled paper reduces about 50% of the energy it takes to make unrecycled paper.
Name: Plastic bag
- How long do they take to decompose? 10 to 1000 years
- What resource/fossil fuel are they made from? They are made from oils and even natural gases.
- How is this resource recycled? Plastic bags can be recycled by melting down, that melted plastic can then be turned into new plastic bags.
- How does this object contribute to climate change? About a tonne of recycled plastic saves up around 4,100 kWh of energy as well as as16.8 barrels of oil; 98 million BTU's of energy and 30 cubic yards of landfill space.
Name: Aluminum can
- How long do they take to decompose? 200 to 500 years
- What resource/fossil fuel are they made from? Aluminium and other types of metal.
- How is this resource recycled? Aluminium cans are recycled similar to plastic, the cans are melted and turned into aluminium ingots; then turned back into aluminium cans or any other products.
- How does this object contribute to climate change? Recycling aluminium saves up to 95% of energy compared to extracting it from its original source.
Name: Leaves
- How long do they take to decompose? 1 to 12 months depending on the type or temperature.
- What resource/fossil fuel are they made from? Trees, plants, etc.
- How is this resource recycled? Mulch Mowing; being left alone where they naturally are.
- How does this object contribute to climate change? By burning leaves and not leaving them alone would contribute to our carbon footprint.
Name: Styrofoam
- How long do they take to decompose? forever.
- What resource/fossil fuel are they made from? Petroleum/oils.
- How is this resource recycled? Strofoam can be reused however not recycled as such.
- How does this object contribute to climate change? Styrofoam manufacturing process affects the atmosphere as chemicals from making it causes air pollution.
