​What I Need to Know

​Waste Management refers to the practice of proper waste disposal. Waste refers to used or consumed products or materials. A very good example of this is garbage. Waste Management is implemented anywhere to clean the environment and make everyone healthy. The kind of waste management we follow nowadays is the 5Rs in Waste

Management (Reduce, Reuse, Recycle, Recover, Repair).

​

​The ultimate goal of the 5Rs to waste management is to free planet Earth from any kind of garbage’s situation referred to as zero waste. Each “R” focuses on a way to achieve “zero waste”. Designing a product out of local recyclable solid and/or liquid materials in making useful products is an application of waste management. With this technique, the 5Rs in Waste Management will also be applied, which is more on recycling.

​

​Recycling the materials to a new product design, reduce waste as much as

possible. Non-biodegradable materials such as plastic, metals, cans and rubbers will be reduced through reusing and recycling.

Recycling is one of the simple things that you can do which results to a positive impact for the environment. Recycling is important to the natural environment and us. We must act fast as the amount of waste we create is increasing all the time.
