Describe 5R's in detail

Refuse: the first element of the 5 R's hierarchy. Learning to refuse waste can take some practice, but incorporating this step into your business' strategy is the most effective way to minimize waste.

Reduce the use of harmful, wasteful, and non-recyclable products. Reducing dependency on these kinds of products results in less waste materials ending up in landfill and the associated negative environmental impacts. We recommend always using the minimum amount required to avoid unnecessary waste.

Reuse: Single-use plastics have created a "throw-away" culture by normalizing consumer behavior of using materials once and then throwing them away. The rate at which we consume plastics has become unimaginable, and the plastic crisis has become one of the world's greatest environmental challenges. In an effort to reduce waste, reuse items throughout the workplace instead of buying new ones.

REPURPOSE:

For every item that can't be refused, reduced, or reused, try repurposing it. Many people in the green community refer to this method as upcycling. You may be surprised to learn how many common office products serve more than one purpose. Sometimes it requires using some creativity, but the possibilities are endless.

RECYCLE

Last but definitely not least: recycle. Once you've gone through all of the other R's, recycling is the most environmentally friendly waste disposal method.

Okay lol that's a lot

littering streams           is the answer

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
