Compostable vs biodegradable plates — what the two claims mean for procurement
Compostable and biodegradable are not interchangeable. Compostable is the stricter, certifiable claim: a material that breaks down into water, CO₂, biomass and inorganic compounds under a defined, named standard such as EN 13432 or ASTM D6400, leaving no toxic residue. Biodegradable only means a material breaks down through biological action, with no timeframe, conditions or end-products specified. For B2B procurement, only a named compostability standard is defensible.
This is a neutral comparison for buyers specifying disposable tableware. For a material-by-material view, see palm leaf vs PLA plates and the eco-disposables material finder.
Key differences at a glance
- Compostable is certifiable against a named standard (EN 13432, ASTM D6400, OK Compost Home); biodegradable is not.
- “Biodegradable” specifies no timeframe, conditions or end-products — a procurement and regulatory risk on its own.
- Industrial compostability is tested at around 58°C; home compostability at 20–30°C over up to 12 months — a materially stricter regime.
- Palm leaf is a single natural fibre; PLA is a bioplastic that needs industrial composting; bagasse is a moulded sugarcane fibre.
- EU regulatory and procurement practice now treats a bare “biodegradable” claim as inferior to a certified “compostable” claim with a named test standard.
The two claims, defined
The distinction is one of evidence, not marketing. A compostable claim can be tested and certified; a biodegradable claim, on its own, cannot.
| Claim | What it means | Named standard | Conditions & timeframe specified? | Procurement status |
|---|---|---|---|---|
| Compostable | Breaks down into water, CO₂, biomass and inorganic compounds under defined composting conditions, leaving no toxic residue. | EN 13432, ASTM D6400, OK Compost Home / NF T 51-800 | Yes — standard defines temperature, timeframe and disintegration thresholds. | Defensible when backed by a named standard and current test report. |
| Biodegradable | Breaks down through biological processes (bacteria, fungi) into smaller compounds. | None required by the term itself. | No — no timeframe, conditions or end-products specified. | Treated as inferior to a certified compostable claim under EU practice. |

Palm leaf, PLA and bagasse compared
The spine below sets out how the three most common eco-disposable materials sit against the compostability attributes that matter in a tender or retailer specification.
| Material | Material class | Named standard route | Home compostable | Industrial compostable | Typical breakdown time | Food-contact basis |
|---|---|---|---|---|---|---|
| Palm leaf (Areca) | Single natural pressed fibre — no plastic, coating or additive | EN 13432 in progress | Yes — breaks down in standard soil | Yes | 90–120 days in standard soil conditions | LFGB §30 §31; EU 1935/2004 migration tested |
| PLA | Bioplastic (polylactic acid) from fermented plant starch | ASTM D6400 / EN 13432 (industrial) | No, not reliably — needs 58°C+ | Yes, at 58°C+ industrial facilities | 90–180 days, industrial only | Food-grade resin; in scope of EU SUP Directive 2019/904 |
| Bagasse | Moulded sugarcane fibre | ASTM D6400 / EN 13432 achievable | Partial / slow at home | Yes | ~60–90 days, industrial | Food-contact grade; confirm coating / PFAS-free status per product |

Use a compostable claim when
A buyer, retailer or public tender requires a named standard (EN 13432, ASTM D6400 or OK Compost Home) supported by a current third-party test report.
Treat a biodegradable claim with caution when
No standard or timeframe is stated. On its own, “biodegradable” is not a defensible procurement claim under current EU practice.
EVIDENCE · PALM LEAF COLUMN
Ecodyne’s palm leaf tableware is pressed from naturally fallen Areca catechu leaf sheaths with no plastic, coating, dye, glue or additive — a single natural material. Food-contact safety is documented under LFGB §30 §31 and EU Regulation 1935/2004 migration testing; EN 13432 compostability certification is in progress. Independent PFAS testing by TÜV Nord returned “not detected”. Supporting reports are released to qualified buyers through a documentation request.
Frequently asked questions
What is the difference between compostable and biodegradable?
Compostable is the stricter, certifiable claim: a material that breaks down into water, CO₂, biomass and inorganic compounds under a defined composting standard, leaving no toxic residue. Biodegradable only means a material breaks down through biological processes into smaller compounds — the term specifies no timeframe, conditions or end-products. EU regulatory and procurement practice now treats “biodegradable” as inferior to a certifiable “compostable” claim with a named test standard.
Which standard proves a plate is compostable?
A compostability claim needs a named standard and a current third-party test report. The recognised standards are EN 13432 (EU industrial), ASTM D6400 (US industrial) and OK Compost Home / NF T 51-800 (home). Marketing copy that says “compostable” without a named standard is a procurement and regulatory risk.
What is the difference between EN 13432 and OK Compost Home?
EN 13432 certifies industrial compostability, tested at around 58°C in controlled facilities. OK Compost Home / NF T 51-800 is the TÜV Austria home-compostability scheme, tested at 20–30°C over up to 12 months — a materially stricter regime, increasingly required under Loi AGEC and its EU national derivatives.
Are PLA plates home compostable?
No, not reliably. PLA requires industrial composting at 58°C+ to break down within typical certification timeframes (90–180 days). In a typical garden or home compost heap — which rarely exceeds 30–40°C — PLA degrades very slowly and behaves more like conventional plastic. Home-compostability claims for PLA should be treated as a marketing risk, not a functional property.
Are palm leaf plates compostable or biodegradable?
Palm leaf plates are a single natural fibre pressed from fallen areca leaf, with no plastic, coating or additive, so they biodegrade in standard soil conditions in about 90–120 days. Ecodyne’s EN 13432 compostability certification is in progress, and food-contact safety is documented under LFGB §30 §31.
Is bagasse compostable?
Bagasse (sugarcane fibre) is compostable and can be certified to ASTM D6400 or EN 13432 for industrial composting. Home-composting performance is slower and depends on the specific product, so buyers should confirm the named standard and whether any coating or PFAS treatment is present.

Ecodyne perspective
ECODYNE PERSPECTIVE
Ecodyne positions palm leaf tableware within the compostable category rather than the looser biodegradable one, because the distinction decides real procurement outcomes in public tenders and retailer specifications. The material is a single pressed areca leaf sheath with no plastic, coating or additive; its EN 13432 compostability certification is in progress, and food-contact safety is already documented under LFGB §30 §31. For a buyer weighing palm leaf against PLA or bagasse, the deciding question is not whether a product “biodegrades” but which named standard and current test report stand behind the claim.
Comparing compostable tableware for a tender or retailer spec?
Ecodyne releases EN 13432 progress status, LFGB §30 §31 reports and TÜV Nord PFAS testing through a documentation request, alongside the biodegradable plates wholesale terms. Match the claim to the named standard your buyer requires.
