These are notes on Recycling.

1. Recycling of
Manufactured Materials

2. What is Recycling?
Why is it important to all of us?

3. Definition
Recycle: To treat or process used materials so
they can be used again
This stops us from wasting material

4. RECYCLING IS
IMPORTANT BECUASE
•It reduces the amount of fresh raw materials we
use
•It reduces the amount of energy we use
•It reduces air pollution
•It reduces water pollution
•It lowers the amount of greenhouse gas

6. Did youknow?….
During yourlifetime that youwill produceso
much trashitwill weigh 600 times as muchas
you

7. Challenges of Recycling
1. It is costly to recycle products than to make the
products from its raw materials
2. It is difficult to separate different manufactured
materials into groups such as plastics, rubber and metal
3. Time consuming process
4. A certain amount of materials must be accumulated
before it can be transported to the factory to be
recycled

The detrimental effects of plastics on
wildlife are well documented, particularly
in aquatic environments.

18. Plastics Fragments Ingested by
Marine Organisms
“…studies have demonstrated that microplastics are ingested by a large variety of
marine taxa…including birds, mammals, fish and invertebrates…microplastics
can be passed through the food web as predators consume prey.” (GESAMP
2015)
… filter-feeding animals, such as mucous web feeding jellies and salps,
were…heavily impacted by plastic fragments... Filter feeders are at the lower end
of the food chain, …fifty species of fish and many turtles are known to eat
them… accumulating plastic in their stomachs.” (Tamanaha & Moore, 2007)

21. Recycling is the change of a material into a new
product to prevent wastage.
Materials can be classified as: Biodegradable or
Non-Biodegradable.
Biodegradable materials can be broken down by
natural processes into simpler forms. Examples of
biodegradable materials are: food scraps, paper,
sewage, remains of dead organisms.

23. Non-biodegradable materials cannot be broken
down by natural processes over many years.
Examples of non-biodegradable materials are:
plastic bottles, batteries, appliances, glass,
Styrofoam and rubber materials.

24. Composting
The controlled biological decomposition of organic
materials.
Compost is organic material that has been decomposed
and recycled as fertilizer

25. Benefits of Composting
Improves the quality of the soil
It contains a variety of nutrients required for healthy growth of plants
In addition to nitrogen, phosphorous and potassium, certain micronutrinets are also
found in compost which helps to control pests and diseases.
Compost improves the structure and texture of the soil, enable them to retain
nutrients, moisture and air for better plant growth
