Fully Biodegradable Eco-Friendly Bags: Decomposition, Standards, and Sizes Explained

What You Need to Know First

Biodegradable plastic takes anywhere from 3 months to over 1,000 years to decompose depending on the specific plastic type, the environment in which it breaks down, and whether it has been certified to a recognized standard. The label "biodegradable" by itself tells you almost nothing useful without additional context about conditions and timescale. Compostable plastics, by contrast, are required under ASTM D6400 to break down within 180 days in a controlled industrial composting environment. These are fundamentally different performance claims.

The practical takeaway for buyers, businesses, and sustainability managers is this: if you want plastic bags or packaging that will break down completely and safely in a defined timeframe, look for products certified to ASTM D6400 (United States) or EN 13432 (European Union) rather than products labeled simply as biodegradable. When selecting Fully Biodegradable Eco-Friendly Bags or a Fully Degradable Flat-Bottom Bag for commercial or household use, certification to one of these standards is the only reliable guarantee of genuine environmental performance. Choosing the right bin bag sizes that match your waste volume is a separate but equally practical consideration that this guide also addresses.

Define Biodegradable: What the Term Actually Means Scientifically

To define biodegradable accurately is to understand the specific biological and chemical process the term describes. Biodegradable means capable of being broken down by the action of living organisms, primarily bacteria and fungi, into simpler chemical compounds including water, carbon dioxide, and in anaerobic (oxygen-free) conditions, methane. Every organic material on earth is technically biodegradable given enough time and the right microbial conditions. The meaningful question is not whether a material is biodegradable but under what conditions it degrades and how long the process takes.

The Problem with Unqualified Biodegradable Claims

The word "biodegradable" on a product label without further qualification is essentially meaningless from an environmental performance standpoint. A conventional polyethylene plastic bag will break down into smaller and smaller fragments over decades to centuries in sunlight and wind through a process called photodegradation, and the remaining microplastic fragments will eventually be consumed by soil microorganisms over hundreds of additional years. Under the broadest possible definition of biodegradable, this process qualifies as biodegradation. But it clearly does not represent the environmentally beneficial rapid decomposition that consumers expect when they see a biodegradable label.

Regulatory bodies in multiple markets have responded to this ambiguity with specific requirements. The United States Federal Trade Commission (FTC) Green Guides (16 CFR Part 260) state that a biodegradable claim is deceptive unless the product will completely break down and return to nature in a reasonably short period of time after disposal, which the FTC interprets as within one year under typical disposal conditions. The EU is implementing the Green Claims Directive, which will require substantiation of biodegradable claims with standardized test data before products can carry the label in European markets.

The Different Types of Biodegradable Plastic and Their Actual Decomposition Timescales

Not all biodegradable plastics are created equal. The material chemistry and the intended decomposition environment determine actual performance:

• PLA (Polylactic acid): Derived from corn starch or sugarcane. Breaks down in industrial composting conditions (58 degrees Celsius, high humidity, active microbial environment) in 60 to 90 days. In home composting or soil, PLA may take 1 to 5 years. In cold water or landfill, it can persist for decades with minimal degradation. PLA is the most widely used bioplastic in Fully Biodegradable Eco-Friendly Bags and food service packaging.
• PBAT (Polybutylene adipate terephthalate): A petroleum-derived but genuinely biodegradable polymer often blended with PLA or starch to improve flexibility and strength. Breaks down in industrial composting in 90 to 180 days. Also biodegrades in soil, though more slowly than in composting conditions.
• PHA (Polyhydroxyalkanoate): Produced by bacteria as an energy storage material. Among the most genuinely biodegradable plastics, capable of degrading in soil, seawater, and home compost conditions in 3 to 12 months depending on conditions. More expensive to produce than PLA or PBAT, which limits its widespread use.
• Thermoplastic starch (TPS): Starch-based bioplastic that degrades rapidly in composting (2 to 6 weeks) and soil (2 to 4 months). Often blended with PBAT to improve water resistance and mechanical properties for bag applications.
• Oxo-degradable plastic (conventional plastic with pro-oxidant additives): This category is critically important to distinguish from genuine biodegradable plastics. Oxo-degradable plastics fragment into microplastics under UV or heat exposure but do not biodegrade in the biological sense. The European Union has banned oxo-degradable plastics under Single-Use Plastics Directive 2019/904 because they contribute to microplastic pollution rather than solving it. Products containing oxo-additive technology should not be classified or marketed as biodegradable.

How Long Does It Take Biodegradable Plastic to Decompose: A Direct Answer by Material

Compostable vs Biodegradable: Understanding the Critical Distinction

The compostable vs biodegradable distinction is the most consequential labeling question in sustainable packaging today, yet it remains widely misunderstood by both consumers and some product marketers. The confusion is understandable because the words sound similar and are often used interchangeably in casual contexts, but they describe fundamentally different performance claims backed by different evidence standards.

Biodegradable: The Broader and Less Specific Category

Biodegradable means the material can be broken down by biological organisms. As established in the previous section, this can happen over a wide range of timescales depending on conditions. Biodegradable is not a standardized claim backed by a single test or certification. A product can legitimately be described as biodegradable if it breaks down in soil over 10 years, even though most consumers would find this timeframe unsatisfactory for a product they believe is environmentally preferable.

Critically, biodegradable products may also leave behind residues including heavy metals, chemical additives, and microplastic fragments during the breakdown process. The biodegradable label says nothing about the quality or safety of the decomposition products, only that organic breakdown occurs to some extent.

Compostable: The More Specific and Verifiable Standard

Compostable materials meet specific performance requirements for both the rate and the quality of breakdown. A compostable material must:

• Break down at a defined rate (typically 90% conversion to carbon dioxide within 180 days under ASTM D6400, or 90 days under more stringent standards)
• Disintegrate into non-visible particles (no fragments larger than 2mm after the composting test period)
• Leave behind compost that is safe for plant growth (the resulting compost must not contain heavy metals above specified limits and must not negatively affect plant germination or growth compared to a control compost)
• Not introduce harmful substances or ecotoxic residues into the compost

In practical terms, every compostable material is also biodegradable, but not every biodegradable material is compostable. A material that biodegrades slowly over decades, or that leaves behind microplastic fragments or toxic residues during breakdown, is not compostable even though it technically biodegrades eventually.

Industrial Composting vs Home Composting: Why the Distinction Matters for Compostable vs Biodegradable Products

Most compostable plastic certifications, including ASTM D6400 and EN 13432, are based on industrial composting conditions. Industrial composting facilities maintain temperatures of 55 to 65 degrees Celsius, high oxygen levels through regular turning, and controlled moisture, creating the ideal conditions for rapid microbial breakdown of certified compostable materials. Many materials certified under these standards do not break down effectively in home compost bins or backyard compost piles, which operate at much lower temperatures (15 to 40 degrees Celsius) with less controlled moisture and turning frequency.

A PLA bag certified to ASTM D6400 for industrial composting may take 1 to 5 years to fully break down in a home compost bin, which is a significant performance gap that many consumers do not realize when they purchase products labeled simply as "compostable." Products certified to the OK Compost HOME standard (issued by TUV Austria) or the AS 5810 Australian home compostable standard are specifically tested under home composting conditions and represent a genuinely more accessible end-of-life pathway for household users.

ASTM D6400 Compostable Plastics Standard Summary: What It Requires

ASTM D6400 is the American Society for Testing and Materials standard specification for plastics and products based on resins derived from renewable resources that are designed to be composted in municipal or industrial aerobic composting facilities. It is the most widely referenced certification standard for compostable plastics in North American markets and is accepted as equivalent or superior to EN 13432 in many international markets.

The Four Testing Requirements of ASTM D6400

ASTM D6400 requires that certified materials pass four distinct tests, each addressing a different aspect of composting performance:

• Biodegradation test (ASTM D5338): The plastic material is exposed to a mixture of mature compost, water, and air at 58 degrees Celsius (plus or minus 2 degrees). The material must achieve 90% conversion of its organic carbon to carbon dioxide within 180 days, or within the same timeframe as a positive control material (cellulose), relative to the maximum theoretical carbon dioxide release of the material. This test confirms that the material is genuinely broken down by biological activity, not merely physically fragmented.
• Disintegration test (ASTM D5338 visual method or ASTM D5338 mesh sieve test): After 12 weeks of composting, no more than 10% of the original dry weight of the material may remain on a 2mm mesh sieve. This test confirms that the material physically breaks down into particles small enough to be undetectable in finished compost, which is important for the practical acceptability of compostable products to composting facility operators who cannot accept contamination of their compost product.
• Ecotoxicity test (ASTM E1197 and OECD 208 plant germination test): The compost produced from the test material is mixed with standard compost and used as a growing medium for plant germination tests. The germination rate and plant biomass in compost containing the test material must not be significantly less than in control compost without the test material. This test confirms that the breakdown products of the compostable plastic do not harm plants or soil biology.
• Heavy metals and fluorine content (ASTM D6400 Table 1 limits): The plastic material must not contain heavy metals including arsenic, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc above specified limits. The standard sets specific maximum concentrations for each metal, typically in the range of 0.5 to 50 mg/kg dry weight depending on the metal. This requirement ensures that compostable plastics do not introduce toxic metals into agricultural compost that may then enter the food chain through soil.

ASTM D6400 Certification Bodies and How to Verify Compliance

ASTM D6400 certification is issued by accredited third-party certification bodies rather than by ASTM directly. The two most widely recognized certification bodies for ASTM D6400 in North American and global markets are:

• BPI (Biodegradable Products Institute): The leading North American certification body for compostable products. BPI certification confirms that a product has been tested by an accredited laboratory against all ASTM D6400 requirements. The BPI logo on a product is verifiable against the BPI online database of certified products, which allows buyers and composting facilities to confirm that a specific product carrying the BPI logo has active certification status.
• TUV Austria OK Compost INDUSTRIAL: The European equivalent certification under EN 13432, which is technically aligned with ASTM D6400. Many products sold globally carry TUV Austria certification because it is accepted in both EU and many non-EU markets, simplifying the certification burden for international product sales.

Buyers should always verify certification against the certifying body's online database rather than relying solely on the logo printed on the product packaging, because logos can be misused on non-certified products, and certification can lapse after the initial certification period without the product being retested.

Bin Bag Sizes: The Practical Guide to Choosing the Right Size

Selecting the correct bin bag sizes for domestic and commercial use is a straightforward but practically important decision. Using a bag that is too small results in overfilling and torn bags that create mess and hygiene problems. Using a bag that is too large wastes material and often results in the bag slipping down into the bin because there is insufficient waste volume to hold it in place at the rim.

Standard Bin Bag Sizes by Bin Type and Capacity

Bin bags are sized by their volume capacity in liters, which should match or slightly exceed the capacity of the bin they are intended to line. The following reference covers the most common bin types in residential and light commercial use:

Choosing Bin Bag Thickness: Micron and Gauge Explained

Bin bag thickness is measured in microns (one micron equals one thousandth of a millimeter) or in gauge for some North American market products. The correct thickness for a given application depends on the weight and sharpness of the waste being contained:

• 10 to 15 microns: Very light duty. Suitable only for dry paper waste, tissues, and light domestic recycling. Will tear under the weight of wet or food waste.
• 20 to 30 microns: Standard domestic bin liner. Appropriate for general household kitchen waste at moderate fill weights. The most common specification for standard household Fully Biodegradable Eco-Friendly Bags in 20 to 35 litre sizes.
• 35 to 50 microns: Medium-heavy duty. Appropriate for heavier kitchen waste, catering refuse, and commercial use where bags will be filled to capacity before removal. The standard specification for commercial kitchen bin bags and for Fully Degradable Flat-Bottom Bag products in office and food service environments.
• 60 to 100 microns: Heavy duty. Used for construction site waste, garden waste with sharp branches, and industrial refuse applications. Less commonly produced in biodegradable formulations because the higher material thickness makes it more challenging to achieve the 90% biodegradation requirement within the ASTM D6400 timeframe.

Fully Degradable Flat-Bottom Bag: What Makes This Format Distinct

A Fully Degradable Flat-Bottom Bag is a specific packaging format that combines the ecological credentials of fully degradable materials with a flat-bottom construction that provides superior stability, capacity, and presentation compared to conventional sealed-bottom bags. The flat bottom allows the bag to stand upright independently when filled, which is a significant practical advantage in retail display, food service, and waste management applications where bags must remain stable on a surface without support.

Structural Features of a Fully Degradable Flat-Bottom Bag

The flat-bottom construction in a Fully Degradable Flat-Bottom Bag involves a gusseted base that unfolds when the bag is filled, creating a square or rectangular bottom panel. This construction distributes the weight of the bag contents across the entire base area rather than concentrating it at a single sealed point as in a pillow-bag or fin-seal construction. The practical results are:

• Free-standing capability: The bag stands upright on any flat surface without a bag holder or support frame, which simplifies display and use in retail and food service environments.
• Maximum volume utilization: The flat bottom allows the bag to be filled to its rated volume without the bottom corner seals limiting the effective usable capacity that reduces the practical capacity of non-flat-bottom bags by 15% to 20%.
• Superior shelf presence in retail: Flat-bottom bags with gusseted sides present a professional face to the consumer that is much more visually appealing than crumpled or sagging alternatives, making them the format of choice for premium and eco-branded retail packaging of dry goods, coffee, pet food, and similar products.
• Structural integrity under load: The flat-bottom construction provides inherently greater resistance to tearing at the base seams because the load is distributed rather than concentrated, which is particularly important for heavy products including food grains, pet food, and soil amendments packaged in degradable bags where bag failure represents a significant product loss and clean-up cost.

Applications for Fully Degradable Flat-Bottom Bags

• Specialty food retail (coffee, tea, dried fruits, spices): Specialty food retailers and producers are among the most active adopters of Fully Degradable Flat-Bottom Bag formats because their customers are disproportionately motivated by environmental considerations and premium product positioning. A compostable coffee bag with a flat bottom and resealable valve closure combines the practical food storage functions of a conventional coffee bag with genuine end-of-life credentials that align with the values of the specialty coffee market.
• Agricultural and horticulture products: Compost, peat, soil amendments, and potting mixes sold in fully degradable flat-bottom bags allow the entire package including the bag to be added to the garden at end-of-use, eliminating a plastic waste stream at the point of application. This is particularly relevant for products that are genuinely used in composting or garden environments where the bag's degradability is directly relevant to the application.
• Restaurant and food service takeaway: Fully Degradable Flat-Bottom Bags in smaller sizes (1 to 5 litre) are used as takeaway carriers, side dish containers, and portion bags in food service environments where regulatory requirements or business policy mandates the elimination of conventional plastic packaging.
• Organic waste collection: Many municipal composting programs use flat-bottom compostable bags as the primary collection vessel for food and organic waste, because the flat bottom allows the bag to sit stably in the kitchen caddy (countertop organic waste collector) and holds its shape while being filled over several days between collections.

Fully Biodegradable Eco-Friendly Bags: Selection Criteria and Verification

Fully Biodegradable Eco-Friendly Bags is the broadest commercial product category within sustainable packaging, encompassing everything from small food-safe produce bags to large garden waste sacks. The "eco-friendly" descriptor is heavily used in marketing but carries no standardized legal definition in most markets, meaning that buyers must apply their own verification criteria to distinguish genuinely superior environmental products from greenwashing.

What to Look for When Buying Fully Biodegradable Eco-Friendly Bags

1. Verify certification to a recognized standard. ASTM D6400 (industrial compostable, US), EN 13432 (industrial compostable, EU), OK Compost HOME (home compostable, global), or AS 5810 (home compostable, Australia) are the credible standards that require third-party testing. A bag that is "made from plants" or "bio-based" without one of these certifications is not verified as biodegradable or compostable in any defined timeframe or condition.
2. Check the material composition. PLA plus PBAT blends are the most common material system for Fully Biodegradable Eco-Friendly Bags because PLA provides rigidity and clarity while PBAT provides the flexibility needed for bag applications. A minimum PBAT content of 30% is typically required to achieve adequate flexibility for bag use without brittleness that causes cracking and premature failure.
3. Confirm the end-of-life pathway available in your location. Industrial compostable bags are of limited practical benefit if there is no industrial composting facility that accepts them in your area. Check whether your local waste authority accepts certified compostable bags in the food and organic waste stream before purchasing compostable bags for organic waste collection. In areas without industrial composting access, home-compostable certified bags (OK Compost HOME) provide a more accessible and genuinely achievable end-of-life pathway.
4. Review the food contact safety if bags will contact food. For Fully Biodegradable Eco-Friendly Bags used for fresh produce, bakery items, or food takeaway, verify that the bag material is certified for food contact under the applicable regulations: EC Regulation 10/2011 for plastic food contact materials in European markets, FDA 21 CFR regulations for United States food contact applications, or equivalent national standards in other markets.
5. Assess shelf life stability before purchase in large quantities. Certified compostable bags are designed to break down and should not be stored in hot, humid, or UV-exposed conditions for extended periods before use. PLA-based bags in particular can become brittle if stored above 40 degrees Celsius for extended periods, and all compostable bags have a finite shelf life that should be checked against the anticipated usage rate before large quantity purchases.

Environmental Benefits of Genuine Fully Biodegradable Eco-Friendly Bags Compared to Conventional Plastic

When certified and properly disposed of through industrial composting, Fully Biodegradable Eco-Friendly Bags deliver measurable environmental benefits compared to conventional polyethylene bags:

• Carbon footprint reduction: PLA bioplastic derived from corn starch has a carbon footprint of approximately 1.3 to 2.4 kg CO2 equivalent per kilogram of material, compared to 2.0 to 3.0 kg CO2e per kilogram for petroleum-derived polyethylene. However, this advantage is partially offset by land use, fertilizer, and processing energy in crop-based bioplastic production.
• Reduction of persistent microplastic pollution: Genuine compostable bags certified to ASTM D6400 leave no detectable plastic particles or fragments in compost after the composting process is complete, unlike oxo-degradable plastics that fragment into microplastics or conventional plastics that persist indefinitely.
• Nutrient return to soil: When compostable bags containing food and organic waste are composted together in industrial facilities, the bag material contributes to the final compost product rather than contaminating it. This integrated organic waste collection approach increases the quality and volume of compost produced per tonne of organic waste collected, improving the economics of municipal composting programs.

Regulatory and Market Landscape for Biodegradable and Compostable Bags

The regulatory environment for biodegradable and compostable bags is evolving rapidly in most major markets, driven by growing concern about plastic pollution, consumer demand for sustainable alternatives, and the growing recognition that unverified biodegradable claims contribute to greenwashing rather than genuine environmental improvement.

Current Regulations Affecting Biodegradable and Compostable Bags

• European Union: The Single-Use Plastics Directive (SUPD) 2019/904 restricts certain single-use plastic products and mandates labeling requirements for products that contain plastic. The EU Green Claims Directive (proposed 2023, expected implementation 2026 to 2027) will require substantiation of environmental claims including biodegradable and compostable labels against recognized standards, which will significantly raise the evidentiary bar for marketing Fully Biodegradable Eco-Friendly Bags in EU markets.
• United States: The FTC Green Guides require that biodegradable claims be supported by reliable scientific evidence that the product breaks down within a reasonably short time after disposal in the typical manner in which it is disposed of. FTC enforcement actions have targeted marketers of biodegradable and oxo-degradable plastic products for unsubstantiated claims, resulting in consent decrees and corrective advertising requirements.
• United Kingdom: The UK Green Claims Code (issued by the Competition and Markets Authority in 2021) requires that environmental claims be truthful, clear, and backed by robust evidence. Products marketed as biodegradable in the UK market are subject to challenge if the claim cannot be substantiated with relevant test data and appropriate qualification of conditions and timeframe.
• Australia: The Australian Consumer Law (ACL) administered by the ACCC prohibits misleading environmental claims. The ACCC has specifically investigated and taken enforcement action against companies making unsubstantiated biodegradable and compostable claims in the Australian market.

Frequently Asked Questions

1. How long does it take biodegradable plastic to decompose in a home compost bin?

The answer depends heavily on the specific type of biodegradable plastic. PLA, the most common material in certified compostable bags, can take 1 to 5 years in a home compost bin because home composting temperatures (typically 15 to 40 degrees Celsius) are far below the 58 degrees Celsius required for rapid PLA breakdown. PHA-based bags and thermoplastic starch bags biodegrade much faster in home compost, often within 3 to 6 months. If you want a bag that will genuinely break down in your home compost, look specifically for products certified to the OK Compost HOME standard or AS 5810, which require testing under actual home composting conditions rather than industrial composting conditions.

2. What is the difference between compostable vs biodegradable bags?

Biodegradable means the bag material can be broken down by microorganisms, but says nothing about how long this takes or what residues remain. Compostable means the bag meets specific standards (such as ASTM D6400 or EN 13432) requiring breakdown within a defined timeframe (typically 180 days in industrial composting), leaving no visible fragments and no ecotoxic residues. All compostable bags are biodegradable, but most biodegradable bags are not compostable. The compostable designation is more meaningful and more verifiable for buyers making environmentally motivated purchasing decisions.

3. What does the ASTM D6400 standard actually require for compostable bags?

ASTM D6400 requires that certified materials pass four tests: a biodegradation test showing 90% carbon conversion to CO2 within 180 days at 58 degrees Celsius; a disintegration test showing no fragments larger than 2mm remain after 12 weeks; an ecotoxicity test confirming the resulting compost does not impair plant germination or growth; and a heavy metals content test confirming that specified metals including arsenic, lead, cadmium, and mercury do not exceed safe limits. Products must be tested by an accredited laboratory and certified by a recognized third party such as BPI to legitimately display ASTM D6400 compliance claims.

4. Which bin bag size should I use for a standard kitchen pedal bin?

A standard kitchen pedal bin with a capacity of 20 to 30 litres requires a bin bag of 25 to 35 litres capacity to provide adequate overhang at the rim to prevent the bag from slipping into the bin as it is filled. The overhang should be at least 10 to 15 cm around the rim to allow secure folding or tucking over the bin edge. A bag sized too close to the bin capacity with minimal overhang will pull down into the bin once the first heavy items are added, making the bag difficult to remove and creating hygiene problems. For a 25-litre kitchen bin, a 30 to 35 litre bag with approximate dimensions of 50 x 60 to 55 x 65 cm is the most practical specification.

5. Can I use a Fully Degradable Flat-Bottom Bag for food storage?

Yes, provided the specific bag you select is certified for food contact under the applicable food safety regulations in your market. Not all Fully Degradable Flat-Bottom Bag products are manufactured with food-grade materials or under food-safe manufacturing conditions. For food contact applications, look for bags that carry both a composting certification (ASTM D6400 or EN 13432) and a food contact safety certification (EC Regulation 10/2011 for EU markets, FDA 21 CFR compliance for US markets). Flat-bottom bags used for dry foods such as coffee, grains, dried fruits, and snacks require food-grade certification; those used for non-food waste collection do not.

6. Do Fully Biodegradable Eco-Friendly Bags break down in a landfill?

Generally no. Landfills are designed to contain waste, not to accelerate biological breakdown. They are typically anaerobic (oxygen-free), lack the active microbial communities that drive rapid biodegradation, and have temperatures far below those needed for certified compostable materials to break down. PLA-based compostable bags placed in a landfill may persist for decades with minimal degradation, performing no better than conventional plastic bags in the landfill environment. The environmental benefit of biodegradable and compostable bags is only realized when they are disposed of through appropriate channels: industrial composting for ASTM D6400 certified bags, or home composting for OK Compost HOME certified bags.

7. What is the shelf life of Fully Biodegradable Eco-Friendly Bags before they start to degrade in storage?

Most PLA-based and starch-based Fully Biodegradable Eco-Friendly Bags have a shelf life of 12 to 24 months under correct storage conditions (cool, dry, away from direct sunlight, below 25 degrees Celsius). Storage in hot, humid conditions significantly accelerates degradation and can cause PLA bags to become brittle and prone to cracking within weeks. PBAT-based bags are generally more storage-stable than pure PLA bags. Buyers purchasing Fully Biodegradable Eco-Friendly Bags in large quantities should verify the manufacturing date, check the stated shelf life, and confirm that storage conditions at the distribution center and end-use location are appropriate to maintain bag integrity until the point of use.

8. Are Fully Biodegradable Eco-Friendly Bags accepted in curbside recycling bins?

No. Compostable and biodegradable bags are not accepted in curbside plastic recycling collections in any mainstream municipal recycling program. They are incompatible with conventional plastic recycling because their different melting points and polymer chemistry contaminate the recycled plastic stream and reduce the quality of the recycled output. Compostable bags must go to composting facilities, not plastic recycling. Placing compostable bags in plastic recycling bins is worse than placing conventional bags there because the contaminant is less easily visible and sorted out at the materials recovery facility.

9. How do I define biodegradable accurately when evaluating product claims?

To define biodegradable accurately for purchasing or compliance purposes, require that any biodegradable claim be accompanied by three pieces of information: the specific test standard used to verify biodegradability, the conditions (temperature, environment, oxygen level) under which the test was conducted, and the timeframe within which the specified degree of biodegradation occurred. A claim of "biodegradable" without these three qualifications tells you only that the material eventually breaks down under some conditions at some point in time, which is true of virtually every organic material and provides no meaningful basis for environmental decision-making.

10. What bin bag sizes are available in biodegradable or compostable materials?

Fully Biodegradable Eco-Friendly Bags and compostable bin liners are commercially available in all the common bin bag sizes from small 5 to 10 litre bathroom and desk bin liners through 20 to 35 litre kitchen pedal bin liners and up to 80 to 120 litre large bin liners for commercial and garden waste applications. The most widely available sizes in certified compostable formulations are the 10-litre food caddy liner (for organic waste collection) and the 25 to 35 litre kitchen bin liner, because these sizes align with the organic waste collection programs run by many municipal authorities that specifically require certified compostable bags. Very large sizes (above 120 litres) in certified compostable materials are less widely available because the thicker film required for structural integrity at large sizes makes it more challenging to achieve the ASTM D6400 biodegradation test requirements within the 180-day timeframe.
