“Compostable” sounds like a single promise. In practice it splits into two very different disposal pathways — home composting and industrial composting — and a product certified for one isn’t automatically suited to the other.
“Compostable” sounds like a single, simple promise. In practice it splits into two very different disposal pathways, home composting and industrial composting, and a product certified for one isn’t automatically suited to the other. For a buyer specifying packaging, this distinction decides what claim you can honestly make to your customers, and what happens when someone actually tries to dispose of your packaging the way your marketing told them to.
This article breaks down the real differences, why they matter for sourcing, and how to specify the right one to a supplier instead of assuming “compostable” covers both.
The Problem: One Word, Two Very Different Processes
Most compostable packaging in the Indian market is certified for industrial composting. Most customers, when they read “compostable” on a bag, assume they can throw it in a garden compost pile or a kitchen compost bin at home. These two things are not the same, and the gap between them is where a lot of customer disappointment, and a lot of brand credibility, quietly gets lost.
Industrial composting facilities maintain controlled, elevated temperatures, typically 55 to 60 degrees Celsius, consistent moisture, regular turning or aeration, and a managed microbial environment, sustained over weeks. Home composting happens in whatever conditions a person’s backyard, balcony bin, or kitchen composter can produce, usually far cooler, less consistent, and dependent on how attentive the person is. A material engineered and tested to break down under the first set of conditions may sit largely intact under the second.
Industrial and home composting are different processes with different temperature, consistency, and timeframes, and they require separate certifications.
Why It Matters for Your Business
The claim on your packaging has to match the disposal reality available to your customer. If your packaging is certified industrial compostable but your marketing implies it can go into a home compost bin, you’re setting up a mismatch between promise and outcome that the customer, not you, discovers.
India’s composting infrastructure is uneven. Industrial composting facilities exist in and around major metros but aren’t universally accessible, and many customers, even in cities, have no direct route to one. If your packaging depends on facility access your customer doesn’t have, “compostable” becomes a claim that’s technically true and practically meaningless for that specific buyer.
EPR and municipal waste systems increasingly care about this distinction. As Extended Producer Responsibility frameworks mature, compostable packaging is expected to actually reach appropriate composting infrastructure, not general landfill, for the environmental benefit to count. Brands that understand which pathway their packaging is built for are better positioned to guide customers toward correct disposal, and to answer questions about end-of-life accurately in audits.
Certification confusion creates supplier risk. A supplier who doesn’t clearly distinguish which compostability their product is certified for, industrial, home, or both, is a supplier who hasn’t fully thought through their own product’s real-world use case. That’s a signal worth noticing before you commit to a large order.
Industrial Composting: What It Actually Involves
Industrial, or commercial, composting facilities are purpose-built to break down organic material, including certified compostable packaging, at scale. They sustain temperatures in the thermophilic range, roughly 55 to 60 degrees Celsius, for an extended period, which is hot enough to accelerate microbial activity significantly and break down more resistant material structures. Moisture and oxygen levels are actively managed, material is regularly turned to maintain even conditions, and the whole process typically runs on a defined cycle of weeks to a few months.
Most certified compostable plastic packaging in India, tested under IS/ISO 17088, is validated against these industrial conditions specifically. The standard’s timeframes and thresholds assume this level of controlled, sustained heat, not the cooler, inconsistent environment of a home compost heap.
The practical implication for a buyer: if your packaging is only industrial compostable, your honest customer-facing claim is “compostable through industrial composting facilities,” not an unqualified “compostable” that implies any compost setup will do.
Home Composting: A Different, Slower, Less Controlled Process
Home composting, whether a backyard pile, a balcony bin, or a small kitchen composter, generally runs cooler, in the mesophilic range, well below the sustained high heat of an industrial facility. Moisture and aeration depend entirely on how consistently the person maintains the setup. Breakdown, even for materials genuinely suited to it, tends to take considerably longer, and results vary far more from one household to another than industrial composting results do.
For packaging to be legitimately marketed as home compostable, it needs to be certified against a separate, generally stricter, standard, such as TÜV Austria’s OK Compost Home mark. This certification specifically tests materials under lower-temperature, less controlled conditions closer to what a real home setup produces, rather than the elevated, managed conditions of an industrial facility.
A product that passes only the standard IS/ISO 17088 industrial test has not been proven to break down this way, and claiming otherwise, even implicitly through phrasing like “compost it at home,” oversells what’s actually been demonstrated.
Common Misconceptions Worth Correcting
- “Compostable” always means “I can throw it in my garden.” This is the single most common misreading, and it’s usually not the customer’s fault, it’s a gap in how brands communicate the claim. Unless a product carries a specific home compostability certification, this assumption isn’t supported by the underlying test data.
- Industrial composting facilities are widely available. In practice, access is concentrated around major metros and organized municipal or private waste management systems. A brand assuming its customers can “just find a facility” often hasn’t checked how realistic that actually is in the cities and towns it ships to.
- If it doesn’t compost in a home bin, the certification must be fake. Not necessarily. A product can be entirely genuine and IS/ISO 17088 certified while simply never having been tested for, or designed for, home conditions. The certification isn’t false, the assumption about what it covers is.
- Both types of composting produce the same end result, just at different speeds. Not quite. Beyond timeframe, industrial composting’s sustained heat and managed conditions produce more complete, consistent breakdown. Home composting outcomes vary more, and partial breakdown, fragments that visually persist longer, is a more common outcome even for materials that are technically home-compostable.
Helping Customers Dispose of Packaging Correctly
Once you know which certification your packaging holds, the more useful question becomes how to help your customer act on it correctly, rather than leaving them to guess.
For industrial compostable packaging, the most useful thing a brand can do is be specific rather than vague: note on the packaging or product page that the material requires access to an industrial composting facility, and where practical, point toward how a customer might locate municipal or private composting services in their area. This is more work than printing a leaf icon, but it’s what actually closes the gap between certification and real-world outcome.
For genuinely home-compostable packaging, clear, simple instructions, expected timeframe, how to prepare the item, cutting it into smaller pieces, for instance, if that speeds breakdown, and what a successful result looks like, help customers use the certification the way it was actually tested to perform.
Where neither pathway is realistically accessible to a customer, it’s worth being honest that disposal alongside general waste, while not ideal, doesn’t undo the other real benefits of choosing compostable packaging in the first place, avoiding persistent microplastic pollution being the main one, even if the specific composting outcome doesn’t happen for that particular item.
The Two Standards, Side by Side
| Factor | Industrial composting | Home composting |
|---|---|---|
| Temperature range | Elevated, thermophilic (roughly 55–60°C), sustained | Cooler, mesophilic, variable |
| Consistency | Managed, monitored, turned regularly | Depends entirely on the individual’s setup and attention |
| Typical timeframe | Weeks to a few months, defined cycle | Longer, and less predictable |
| Relevant certification | IS/ISO 17088 (India), most standard compostable packaging certifications | Separate certification, e.g. TÜV Austria OK Compost Home |
| Access in India | Limited to facilities, mainly around metros and organized waste management systems | Available to anyone with space and willingness, but results vary |
| What to specify to a supplier | “Certified compostable under IS/ISO 17088 for industrial composting” | “Separately certified for home compostability, not just industrial” |
Examples: Where This Distinction Gets Missed in Practice
The blanket “compostable” claim. A skincare D2C brand markets its mailer bags as simply “compostable” without specifying which pathway. Customers in tier-2 cities without access to industrial composting facilities try home composting instead. Weeks later, several post that the bag hasn’t broken down, prompting confused, slightly frustrated customer service tickets, even though the product was never certified for that use case in the first place.
The supplier who didn’t clarify. A restaurant chain’s packaging supplier describes their takeaway container line as “fully compostable” in every sales conversation, without distinguishing industrial from home. The chain assumes this means customers can compost the containers at home if they choose, and communicates that to end customers. No home-compostable certification exists for the product; only the standard industrial test was ever conducted.
The correct, specific claim. A courier bag brand states clearly on the product page: “IS 17088 certified compostable, designed for industrial composting facilities. Check for a composting facility near you before disposal.” Customer complaints about disposal are close to zero, because the expectation set matches what the product can actually deliver.
A Buyer’s Checklist for Specifying the Right Composting Claim
- Ask your supplier directly: is this product certified for industrial composting, home composting, or both, and under which specific standards?
- If claiming home compostability, confirm a separate certification exists, such as OK Compost Home, rather than assuming IS/ISO 17088 covers it.
- Match your customer-facing language to the certification you actually hold. “Industrial compostable” and “compostable” are not interchangeable claims to a well-informed customer.
- If most of your customer base doesn’t have practical access to industrial composting facilities, factor that into how you talk about disposal, and consider whether guidance on locating a facility adds more value than a vague claim.
- Ask your supplier for the test report showing which conditions the product was actually tested under, not just a certificate that says “compostable.”
- Revisit this any time you change resin formulation, thickness, or supplier, since compostability behaviour can change with the product itself.
Key Takeaways
- Industrial and home composting are different processes with different temperature, consistency, and timeframes, and they require separate certifications.
- Most standard compostable packaging in India is certified for industrial composting only, under IS/ISO 17088.
- Home compostability requires a distinct, generally stricter certification, and shouldn’t be assumed or implied without it.
- Access to industrial composting facilities is uneven across India, which should shape how a brand communicates disposal to customers.
- The safest approach is specifying the exact certification a product holds to your supplier, and matching your customer-facing claim to it precisely.
