Frequently Asked Question
How long does a compostable material take to break down?
Breakdown time depends on the material, the composting environment, and the conditions in which it is processed. Industrial composting generally provides faster and more consistent breakdown than home composting. The time required for breakdown does not, by itself, indicate environmental performance or safe reintegration.
What is a compostable material?
A compostable material is a material that can be broken down by microorganisms under defined composting conditions. These conditions include controlled temperature, moisture, oxygen, and microbial activity and are specified by recognised compostability standards.
What is the difference between plastic and bioplastic?
Plastic typically refers to synthetic polymer materials derived from fossil fuels, while bioplastics may be bio-based, biodegradable, or both. The term bioplastic does not define behaviour or environmental outcome. A bioplastic can still contain synthetic additives, produce microplastics, or require specific industrial conditions to degrade. Origin and composition are not the same as behaviour.

What is eco-friendly packaging?
Eco-friendly packaging is a broad, non-standardised term used to describe packaging designed to reduce environmental impact. It does not define what a material is made of, how it behaves after use, or whether it leaves persistent residues. A package can be labelled eco-friendly while still producing microplastics or requiring specific industrial conditions to break down. When evaluating packaging materials, behaviour after use, not the label, is what determines actual environmental outcome.
Within the Solinatra approach, materials are assessed based on behaviour, including breakdown, residue formation, and safe reintegration into natural systems.

Do biodegradable plastics leave microplastics?
Some biodegradable plastics can leave microplastics if they do not fully break down. Biodegradability does not guarantee complete reintegration, and materials may fragment into persistent particles depending on composition and environment.

Are bioplastics compostable?
Some bioplastics are compostable, but not all. The term bioplastic includes materials that are bio-based, biodegradable, or both, and compostability depends on specific material composition and conditions.

Biodegradable vs compostable: what is the difference?
Biodegradable materials break down by biological processes over time, while compostable materials are designed to break down under defined conditions such as industrial compostable standard within set timeframe. The difference lies in predictability and control, as biodegradability does not define timeframe or outcome, while compostability refers to specific processes.

How long does compostable material take to break down?
The time required for compostable materials to break down depends on the conditions in which they are processed. Industrial composting typically operates under controlled temperature and humidity, which can accelerate breakdown. Home composting conditions vary significantly and may result in slower or incomplete degradation. Breakdown time is one data point and does not indicate whether a material safely reintegrates into natural systems.

What is the difference between home composting and industrial composting?
Home composting and industrial composting differ in conditions, consistency, and outcome.
Industrial composting operates under controlled temperature, humidity, and airflow — typically above 55°C — which accelerates breakdown and produces consistent results. Materials processed this way break down within a defined timeframe under managed conditions.
Home composting is variable. Temperature, moisture, and microbial activity depend on the individual setup and climate. Materials that break down reliably in industrial conditions may degrade much more slowly — or incompletely — at home.
The practical difference matters: a material certified for industrial composting is not automatically suitable for home composting.
Solinatra materials are designed for both conditions depending on the grade and end-applications. For technical data on breakdown behaviour, request our TDS.
Home composting and industrial composting use the same biological process but operate under different conditions.
Industrial composting uses controlled temperature, moisture, oxygen, and microbial activity to achieve consistent breakdown within defined conditions. Home composting depends on local climate and individual compost systems, so breakdown may occur more slowly or vary between locations.
Some materials are suitable for industrial composting only, while others are designed for both industrial and home composting. The appropriate end-of-life route depends on the material grade and intended application.
What is compostable material?
Compostable material is a material that breaks down under defined composting conditions, such as those set by EN 13432 for industrial composting or ISO 20200 for controlled conditions. Compostability is assessed against specific temperature, humidity, and time parameters. It does not guarantee breakdown in all environments, and it does not guarantee that no persistent residues remain.

What is biodegradable material?
Biodegradable material is a material that can be broken down by biological processes under specific conditions. Within the Solinatra framework, biodegradability is only one aspect of evaluation; it must be considered alongside the material's overall real-world behavior and safe reintegration into natural systems.

Do compostable materials leave microplastics?
Some materials labeled as compostable may still leave microplastics depending on their specific composition and behavior. Within the Solinatra framework, materials are specifically evaluated to ensure they do not create persistent microplastics and can safely integrate with natural systems.
Whether a compostable material leaves microplastics depends on its composition and how it degrades. Compostability alone does not determine whether persistent microplastics are formed.
What is the difference between biodegradable and compostable?
Biodegradable materials are any materials that can break down over time through biological processes. Compostable materials are specifically designed to break down under defined, controlled conditions. In the Solinatra framework, the key is to ensure material breakdown achieves safe reintegration into natural systems without leaving persistent residues.
Biodegradable describes a material that can be broken down by microorganisms under suitable conditions. Compostable describes a material that meets recognised standards for breakdown under defined composting conditions. Compostable materials are biodegradable, but not all biodegradable materials are compostable.
