Answers
Explanation:
The concept of 5R's is to decrease the amount of things we use and simultaneously also decrease the amount of things we throw away. Since we have limited space on earth to dispose all the waste, it is important to use the resources efficiently and create less waste.

Answer:
Reduce
Reducing waste is the most important thing we can do. By reducing waste, we avoid the unnecessary use of resources such as materials, energy and water. It means there is less waste to manage.
Reuse
The next most important thing we can do is reuse waste material. That way it doesn't go in the rubbish and end up in the landfill. It also means you don't have to buy a new product. That saves you money and saves the energy and resources that would have been used to make the new product.
Recycle
Recycling involves some form of reprocessing of waste materials to produce another product. For example, recycling plastic bottles to make buckets.
What can be recycled?
- The main products that can be recycled are paper, cardboard, glass, aluminium, tin and plastic containers.
- Composting and worm farms are methods of recycling organic waste.
Buy recycled
You can buy products that are made from recycled materials.
Recycling in your district
Different districts collect different recyclables at the kerbside and at their transfer stations/resource recovery parks. Contact your local city or district council to find out what they collect.
Recover
This is the recovery of waste without any pre-processing. For example, waste oils that cannot be refined for reuse in vehicles can be burnt for energy recovery. Recovering the energy from waste oil reduces our dependence on coal and imported oil.
Residual Management
This is the last option when waste cannot be used in any other way. Usually, this means sending rubbish to a landfill. Residual disposal of liquid waste is normally into a sewer or septic tank.
