The Circular Economy: An Introduction

A term that often pops up while reading about sustainable development, efficiency or growth is "circular economy". We should aim to shift towards a circular economy model to reduce our environmental footprint, optimize costs, produce efficiently... and so on. But what is the circular economy? Why should businesses, industries and people care? This post should serve as a short introduction to the concept. 

Essentially, the circular economy is the more sustainable alternative to our current "linear" economy system. 

What most industries do right now is: Take, Make and Dispose. Extract resources, process them into products, dispose off after use as waste. This is a linear system, the waste after use ultimately goes back to the earth and is, more often than not, toxic, unusable or takes long to biodegrade. Our economy runs on this linear chain of events.

In the long run, this is definitely not a sustainable approach, since we can only "take" so much from a finite planet and "dispose" only so much in a finite area. Remember, when we think we're throwing things "away", there really is no away in the first place. One's waste is another's food. We need new patterns of production and new systems of thinking. 

In a circular economy model, we learn from the Earth's natural systems. Whatever nature produces, goes back to nature and this cycle indefinitely repeats (a very simple example would be, a plant grows from the soil, lives and uses water/resources, dies and decomposes back into soil providing nutrients for other plants). Somebody's waste is someone else's food. Similarly, circular economy takes inspiration from natural processes so as to design methods, products or business models that are similar to this regenerative process.

How is this done -- by making sure the "technological" and "biological" factors of the entire process are a part of a bigger material cycle designed for reusability or repurposing. There is a variety of ways to go about doing this. Alter your product or business model accordingly to provide for maintenance or end-of-product-life services; use materials that can last longer or be used again with minimal energy; use renewable energy sources at each step of the process; understand how one part of the process will affect other parts (thinking in systems). A simple image that can help explain this cycle:

The circular economy model (though not very easy to achieve) is ultimately less wasteful, uses resources more efficiently, and more industries should adopt the process for long-term overall sustainable development.

Understanding Indian Classical Music

If you feel like you're in an alien country every time somebody discusses Indian Classical music around you, this could help. Swars (or swaras)                                                                  Essentially, all of Indian classical music is made up of 12 notes. These are called swars (or swaras ) . There are seven basic swars , one step away from each other. 1. Sa 2. Re 3. Ga 4. Ma 5. Pa 6. Dha 7. Ni

On Being a Teen

[Edit: Nearly two years after writing this, I  realize how quickly I've grown and thoughts have changed over time, I feel quite differently about being a teenager now! I'm pretty sure I'll say this again next year...] Someone asked what it feels like to be a teenager in 2014.  I'm 17, and I can say, being a teen is something I like as much as I dislike: There are way too many  opportunities  today in 2014, but way too much  competition  too. The idea of being "above-average" has been drilled into our heads, it seems like a normal average person can get nowhere today. There's a bundle of  expectations  from us kids. I have self-set expectations too. Seeing so many people do brilliant things at this age makes me want to be like one of them too. I feel  connected . Technology arrived the right time for our generation, in my opinion. I am Indian, but the whole "global citizen" concept means a lot to me. The internet has helped me connect
