KNOWING THE DIFFERENCE & USING THE BEST MATERIALS:
It’s important for our customers to be educated on eco-terms so that we can all make informed decisions. We want folks to know that we put time and care into researching product materials and that making it easily accessible to you is key for transparency. Many consumers cannot take on the extra burden of researching what certification codes mean so this page is to quickly identify what our certifications mean and who does them.
Remember that the difference between composting and biodegrading is this: The process of composting provides nutrients and fertilizer to the Earth (making nutrient rich soil) and biodegrading is the process of breaking down bio-plastics into innocuous elements that do not harm the environment. The outcome of biodegrading is generally to have a material leave no negative impact while the outcome of composting is to have a nutrient rich by product (soil ) that can be used to grow plants again. So there is a difference in the achievable outcome of a material and there is a difference in the process of degradation. What matters most is that the bio-plastic in these processes does not simply break down into smaller plastic pieces, the material actually transforms into something new. That is why products labeled only ‘degradable’ or ‘oxo-degradable’ do not meet the certification standards of composting and biodegradation.
Compostable bioplastics provide a phenomenal solution to the single-use plastics problem. However, being educated on the certifications required for these products allows for us all to be informed businesses and informed consumers. Within the category of compostables there are two main standards of testing and processing that occur: Industrial composting and home composting. The basic differences between industrial compost and home compost are the volumes at which they can be performed, the conditions under which they occur, and the location where they occur. As per their names, home composting can be done in your own backyard (or anywhere in nature for that matter), while industrial composting occurs in specialized facilities where temperature and other factors can be controlled and adjusted. Home compost is meant for smaller volumes of waste (from a single household for instance), while industrial compost is for entire communities or municipalities, similar to your local landfill or dump. Industrial composting helps to divert food waste and other compostables from landfills, not only reducing the volume of waste in landfills, but helping to lower greenhouse gas emissions as well. A bio-plastic like PLA (poly-lactic acid) for example has the ability to be both industrially and home compostable depending on the form that material takes; our plastic wrap is made from PLA and has the ability to compost at home in under a year but a bottle made from PLA would have to be industrially composted due to the thickness of the material needed to make that form. This is why is is essential to only use products that have certifications. If we understand the conditions required for a bio-plastic object to return to the earth then we can make the choice to use materials that require little maintenance for our customers.
In order to be labeled as “industrially compostable” or “commercially compostable,” there are certain tests and certifications that products must pass. In the US, commercially compostable products are tested via ASTM D6400 protocols and criteria. ASTM is the American Society for Testing and Materials. Standard D6400 is the Standard Specification for the Labeling of Plastics Designed to be Aerobically Composted in Municipal or Industrial Facilities. This standard provides a timeframe in which both disintegration (physical breakdown) and biodegradation/compost production (chemical breakdown) must occur: 180 days. And it also requires that, in the end, the final product is of no harm to the surrounding ecosystem (ie: is non-toxic). The equivalent standard in Europe and other parts of the world is EN 13432, which requires the same timelines and results. Once a product passes testing, the results can be sent to a 3rd-party organization for certification. There are a variety of 3rd-party certifiers worldwide. In the US, the most well known is the Biodegradable Products Institute, or BPI. In Europe, the most known governing body is TUV Austria. They offer their OK compost INDUSTRIAL certification, which is the equivalent of a BPI certification in America. So, when examining a product that is industrially or commercially compostable, keep a look-out for ASTM D6400, EN 13432, BPI, and TUV Industrial logos. Products marked with these logos are certified compostable, and you can rest assured knowing that, if you dispose of them properly, they will live a completely circular lifecycle.
Finally it is crucial to address the common question of biodegradation occurring in landfills. Many of our customers ask how a biodegradable product can break down in a landfill without the presence of oxygen and an increase of toxic and potentially dangerous substances. In a landfill environment, there is no oxygen to convert innocuous elements into usable compost. Therefore, materials in these environments can have the ability to biodegrade, but not to compost. And that is also why a product can be both biodegradable and compostable. The specification partially is determined by how a product is discarded.
In a landfill setting, ASTM D5526 tests for plastic materials that are suitable for anaerobic biodegradation under accelerated landfill conditions. This process not only reduces the volume of waste in landfills, but can also increase the feasibility of economic landfill-gas recovery. There currently is no equivalent to this test standard in other parts of the world. Therefore, products that indicate having passed testing for ASTM D5526 can be classified as certified landfill biodegradable.The goal of using certified landfill biodegradable items is to not add the to already occurring environmental issues within a landfill. Using a single use petroleum plastic item only increases the already existing problem but a product certified under ASTM D5526 will biodegrade without leaving behind anything harmful.
* An additional note on language: We refer to a product as ‘compostable’ or ‘biodegradable’ based on the type of certification it has. For example, if a product is being tested just for home compostability we will refer to it as compostable only. But that does not mean it isn’t also biodegradable. For the sake of clarity we only use the terms pertaining to its test method.
Transparency is our priority.
We will always disclose what our products are made of, how they will decompose and what conditions they require to do so.
Our promise is to always use materials that have the least environmental impact. We want to support the green industry of today to advance the green technology of tomorrow. All our products and materials are certified as biodegradable or compostable by an official party.
The following is a list of the compostable, biodegradable and environmental certifications each of our products hold under North American and European Union standards. The institutions our manufacturers have been certified through are official and recognized internationally. For more information on them scroll to the bottom of the page.
•ASTM D6400 / ASTM D6868: The standard specification for solid material biodegradation (by composting) required for the labeling of plastics designed to be aerobically composted in municipal or industrial facilities. In order to compost satisfactorily, the product must demonstrate each of the three characteristics as follows: (1) proper disintegration during composting; (2) adequate level of inherent biodegradation; and (3) no adverse impacts on the ability of composts to support plant growth.
• ISO 17088:2008: Specifies procedures and requirements for the identification and labelling of plastics, and products made from plastics, that are suitable for recovery through aerobic composting. The four following aspects are addressed:
- disintegration during composting
- negative effects on the composting process and facility
- negative effects on the quality of the resulting compost, including the presence of high levels of regulated metals and other harmful components.
• EN 13432: The industrial standard to be met in order to claim that a plastic product is compostable in the European marketplace. In summary, it requires multiple tests and sets pass/fail criteria, including disintegration (physical and visual break down) of the finished item within 12 weeks, biodegradation (conversion of organic carbon into CO2) of polymeric ingredients within 180 days, plant toxicity and heavy metals. The ASTM6400 standard is the regulatory framework for the United States and as similar requirements.
•ASTM D5526-12: The standard test method for determining Anaerobic biodegradation of plastic materials under accelerated landfill conditions. As degradation occurs inevitably in a landfill, it is of immediate concern that the plastic materials do not produce toxic metabolites or end products under the various conditions that have the potential to occur in a landfill. The mixtures remaining after completion of the test method, containing fully or partially degraded plastic materials or extracts, can be submitted subsequently to ecotoxicity testing in order to assess the environmental hazards posed by the breakdown of plastics to varying degrees in landfills. This test method has been designed to assess biodegradation under optimum and less-than-optimum conditions.
The test materials are mixed with pretreated household waste and exposed to a methanogenic inoculum derived from anaerobic digesters operating only on pretreated household waste. The anaerobic decomposition occurs under dry (more than 30 % total solids) and static nonmixed conditions. The mixtures obtained after this test method can be used to assess the environmental and health risks of plastic materials that are degraded in a landfill.
• EN 13432 The industrial standard which must be met in order to claim that a plastic product is compostable in the European marketplace. In summary, it requires multiple tests and sets pass/fail criteria, including disintegration (physical and visual break down) of the finished item within 12 weeks, biodegradation (conversion of organic carbon into CO2) of polymeric ingredients within 180 days, plant toxicity and heavy metals. The ASTM 6400 standard is the regulatory framework for the United States and as similar requirements. Additive-based bioplastics sold as photodegradable or Oxo-biodegradable do not comply with these standards in their current form.
• Health Canada Number: DIN 02242474
A DIN uniquely identifies the following product characteristics: manufacturer; product name; active ingredient(s); strength(s) of active ingredient(s); pharmaceutical form; route of administration.
A DIN lets the user know that the product has undergone and passed a review of its formulation, labeling and instructions for use. A drug product sold in Canada without a DIN is not in compliance with Canadian law.The DIN is unique and serves as a tool to help in the follow-up of products on the market, recall of products, inspections, and quality monitoring.
• Eco Logo: UL 2794
This is the standard for sustainability for disinfectants and hard surface cleaners that have a reduced environmental impact. Environment Canada started this programme in 1988, to provide information about environmentally-responsible products. The U.S. based for-profit Underwriters Laboratory (now UL) bought it in 2010.
UL 2794 is the standard certification for disinfectants cleaners that meet the strict requirements for eco-sustainability. Here are the major requirements these disinfectants must meet:
a) Toxicity to aquatic and mammalian life
b) Biodegradability/breakdown, performance in the presence of soil; c) Low risk for promoting microbial resistance;
d) Restrict ingredients with negative impacts to air quality (VOCs); e) Human health (e.g., carcinogens);
The test standards for biodegradability fall under ASTM D5660-96, ISO 11348 or EPS report 1/RM/24

By awarding both the OK compost INDUSTRIAL and the Seedling logo, TÜV AUSTRIA’s certificate holders have a way to give their compostable products recognition throughout the entire European market.
OK compost HOME is not based on a standard but is the basis for several standards!
It seems important to remember that the OK compost HOME certification programme does not explicitly refer to a specific standard but details all the technical requirements that a product must meet in order to obtain the certification. It should also be remembered that, as a pioneer in this field, the requirements of the OK compost HOME programme, defined in 2003 and never questioned since then, have served as the basis for the drafting of several standards such as:
- Australia: AS 5810 (2010) – Biodegradable plastics - Biodegradable plastics suitable for home composting
- France: NF T 51800 (2015) – Plastics - Specifications for plastics suitable for home composting
- Europe: prEN 17427 (2020) - Packaging — Requirements and test scheme for carrier bags suitable for treatment in well-managed home composting installations
OK compost INDUSTRIAL (EN 13432)
Packaging or products featuring the OK compost INDUSTRIAL label are guaranteed as biodegradable in an industrial composting plant. This applies to all components, inks and additives. The sole reference point for the certification programme is the harmonised EN 13432: 2000 standard: in any event any product featuring the OK compost INDUSTRIAL logo complies with the requirements of the EU Packaging Directive ( 94/62/EEC).
