If you are from India, you would recall in the good old days there used to be a hawker who would not sell anything rather would take your old clothes and exchange them with steel utensils, new clothes, or some other knick-knacks.
You can term it as a barter system and Indian homemakers used to have a gala time showcasing their negotiation skills.
At some places, we can still spot them, but unfortunately, the steel utensils are replaced with plastic wares. (like the one lady in the picture we spotted in Udaipur, Rajasthan)
It was an excellent system where old clothes were refurbished & restored and sold in other markets (circular economy).
These days many of these clothes, bags, plastic, electronic items are made, consumed, and then thrown out as landfills (linear economy).
What is the difference between Circular Economy and Linear Economy?
Let us take the example of the device on which you are reading this, your cell phone, laptop, or tablet – contains copper, lead, zinc, mercury, arsenic, and many other raw materials that are excavated from the earth’s surface.
Imagine, if humans keep mining and manufacturing these electronic devices and consumers just toss these devices in the landfills after every few years.
Can all the raw materials last forever? Sure, it will get exhausted sooner or later. Unless we find alternatives, our future generations will not have mobile phones. This is Linear Economy.
Another option is to start giving back, whenever we want to change our mobile phone or laptop, instead of throwing it out – we give it to someone, resell it, or give it for recycling. Manufacturers can retrieve the raw materials (copper, lead, zinc, etc.) from the old device and use them to make a new device. This is Circular Economy
Linear Economy is taking the resources -> making the product -> throwing the product ⬇️.
While the Circular economy is about restoring, reusing, repurposing, and recycling 🔄.
If you apply the same logic to say the furniture in your room or the clothes which you are wearing. In the linear model, once you think of replacement of your furniture or your clothes – either it can be thrown in the landfill or it can be reused, repurposed, or restored or recycled. (Please note recycling is part of the circular economy).
Why should we go for a Circular Economy?
From the last few decades with increasing industrialization, consumerism, unlimited choices, fast fashion, high disposable incomes – the prevailing mindset is to buy items and throw them. The linear model makes the system not only unsustainable but has huge environmental repercussions –
- New raw materials need to extracted every time a product needs to be developed. Like zinc, copper, etc in the case of an electronic device or a tree that needs to be chopped for wooden furniture. In addition, we would need energy, water, packaging (plastic), transportation, and other resources.
- The items which are thrown in the landfills – pollute the surroundings & air, take up a vast amount of land, the harmful chemicals from the litter seeps underground which further contaminates the soil and water
A circular economy limits the impact of the linear economy by ensuring that resources remain in the system for a longer period of time. The materials remain in use more than once thereby reducing the extraction of new raw materials and waste minimization.
- The same zinc, copper, etc. can be used to make a second phone or probably many more phones.
- The wood of the wooden dining table can be used to make four side tables and other furniture from the repurposed sawdust.
- The tee shirt can be upcycled as a carrying bag.
Earth resources are limited, hence a model which is dominated by production, consumption, and disposal is untenable. Moreover, with climate change impacts due to pollution and waste, it becomes imperative that we switch towards a circular economy.
While some leakage will happen from the circular economy as not everything can be reused and it might not be resource-effective. Hence it cannot be an ‘either’ and ‘or’ case, but a slow transition.
