These three words are used irresponsibly on packaging today. They’re on cups, containers, carry bags, and coffee sleeves. They’re used interchangeably in marketing, thrown around in sustainability reports as buzzwords, and trusted by well-meaning businesses and consumers who are simply trying to do the right thing. But biodegradable, repulpable, and recyclable mean very different things. And confusing them is exactly how greenwashing works.
Here’s what each one actually means and why it matters every time you pick up a disposable paper cup.
Breaking Down ‘Biodegradable’
Biodegradable, in simple terms, means a material can be broken down by bacteria, fungi, or other living organisms over time. Sounds straightforward, but the problem lies in the fine print. Almost everything is technically biodegradable when given enough time. A conventional PE-coated paper cup is biodegradable, as is a plastic bag and a car tyre. The question is never just whether something breaks down, but how long it takes, what conditions it needs, and more importantly, what it leaves behind.
For a product to be certified compostable under ISO 17088 standards, at least 90% of it must break down within 6 months under composting conditions. PE-coated cups can take up to 20 years. That’s not biodegradable in any meaningful sense; that’s just slow-motion pollution. Even cups made with PLA or BioPBS, plant-based coatings often marketed as biodegradable paper cups, only break down under tightly controlled industrial composting conditions that barely exist at scale in India. Put them in a landfill, which is where most cups end up, and they behave almost identically to conventional plastic.
Breaking Down ‘Recyclable’
Recyclable means a material can be collected, processed, and turned into something new. For paper cups, this is where the story gets complicated. Most disposable paper cups, whether used for tea, coffee, or water, are made of paper bonded to a thin layer of PE plastic. The paper itself is perfectly recyclable. The plastic is not the problem on its own, either. The problem is that they’re fused together, and separating them requires an intensive industrial process that very few facilities in India, or the world, are equipped to handle.
So when a paper cup manufacturer stamps “recyclable” on their cup, they’re technically not wrong. The cup can be recycled, but it hardly is, because the infrastructure to do so doesn’t exist at scale, especially in India. Most recyclable paper cups end up in landfills anyway, where the PE lining leaches microplastics into the soil and releases methane as it slowly degrades. PLA-coated cups face the same recycling problem. The bioplastic coating continues to be on the paper, still requires separation, and also gets rejected by standard paper recycling facilities.
Breaking Down ‘Repulpable’
Repulpable is the least talked-about term and the most practically transformative one for paper cups. A repulpable cup can be broken down and reprocessed alongside regular paper waste, without any special separation or industrial facility. The fibres are recovered and re-enter the paper manufacturing cycle without sorting or specialized equipment. Just paper, back to paper.
This works with ease here because our disposables, including the RAS Bio Cups, use a water-based aqueous coating instead of a plastic film. Unlike PE or PLA, this coating doesn’t sit on top of the paper as a removable layer; it integrates into the paper fibres during drying. There’s no plastic to separate, which means there’s no barrier to recycling.
In fact, for businesses sourcing eco-friendly paper cups in bulk, whether you’re a café, a QSR, a hospital, or an airline, repulpability is the standard that actually creates change in the real world.
What to Look for in an Eco-Friendly Single-Use Product
The next time a supplier or brand tells you their cups are eco-friendly, ask three questions:
- What coating has been used on this paper cup?
- Is the cup repulpable with regular paper waste, or does it need industrial separation?
- Which certifying body has verified the claim, and to what standard?
If the answers are vague, the label probably is too. Plastic-free paper cups in India are still rare, but they exist, and they’re not hard to find or use. They just require asking the right questions.
