It is actually 4 R's. Let me show you what are the 4 r's.
Mark, do you have any idea about waste management?
I only know 3 R's. But I really don't know how to practice it.
Waste management includes the activities and actions required to manage waste from its inception to its final disposal.
I think the first R is Reduce, which is minimizing use of solid waste by using durable, washable, and recycled products.
That's right. Next is Reuse. We should consider buying things that can be reused for different purposes such as plastic containers, rechargeable batteries, etc.
oh. it 's similar to recycling
No, recycling is different. It is the use of waste by processing and modifying it into another form. the process is done when it's impossible to reuse the waste anymore such as paper, glass, metal, etc.
Hahah. I see. That's cool. Thank you for the info. Now what is the last R?
Wow. I had a really good time chatting with you. Thank you for explaining the 4 R's. From now on I will apply the 4R's in our household before disposing our trash.
Recover. It is the process of converting waste product into resources such as fuel, heat, etc. Example: If there is still plastic waste after being reduced, reused and recycled, it can be used to make energy. Methane gas is also recovered from decomposing organic matters.
