As the world moves towards more sustainable practices, terms like “commercially compostable” are becoming increasingly common. But what does commercially compostable mean, and how does it differ from regular composting?
In this article, we’ll break down the definition, process, and benefits of commercial composting, and explain why it’s an important part of reducing waste and protecting the environment.
With growing concerns about plastic pollution and landfill waste, many people are turning to compostable products as a greener alternative. However, not all compostable items are the same. Some are designed for home composting, while others require industrial facilities. This raises the question: What does commercially compostable mean? Let’s explore this concept in detail.
What Does Commercially Compostable Mean?
Commercially compostable refers to products or materials that can break down into natural elements under specific conditions found in industrial composting facilities. These conditions include high temperatures, controlled humidity, and the presence of microorganisms. Unlike home composting, commercial composting can handle a wider range of materials and decompose them more efficiently.
To be considered commercially compostable, products must meet international standards such as ASTM D6400 or EN 13432. These standards ensure that the materials decompose within a specific timeframe (usually 3-6 months) and leave no toxic residues.
Commercially Compostable vs. Home Compostable
Understanding the difference between commercially compostable and home compostable is crucial for proper waste management:
| Feature | Commercially Compostable | Home Compostable |
|---|---|---|
| Conditions | Requires industrial facilities | Can decompose in home compost bins |
| Temperature | High heat (50-60°C) | Lower heat (ambient temperature) |
| Decomposition Time | 3-6 months | 6-12 months or longer |
| Materials | PLA, PHA, certain plant-based materials | Fruit peels, vegetable scraps, etc. |
Commercially compostable products are ideal for items that need faster decomposition or are made from materials that cannot break down in home compost bins.
Common Materials Used in Commercially Compostable Products
Commercially compostable products are made from materials that can withstand high temperatures and break down efficiently in industrial facilities. Here are the most common ones:
- PLA (Polylactic Acid): A biodegradable plastic made from fermented plant starch, often used in food packaging and utensils.
- PHA (Polyhydroxyalkanoates): A bio-based plastic produced by microorganisms, known for its versatility and compostability.
- Cornstarch: A renewable resource used to make compostable bags and containers.
- Sugarcane Bagasse: The fibrous residue left after extracting juice from sugarcane, often used for plates and bowls.
- Cellulose: Derived from plant cell walls, used to make transparent films and coatings.
These materials are chosen for their ability to decompose completely in commercial composting conditions.
How Commercial Composting Works
- Collection: Compostable products are collected from homes, businesses, and institutions.
- Sorting: The waste is sorted to remove non-compostable items.
- Shredding: The materials are shredded to speed up decomposition.
- Heating: The waste is placed in large piles or machines where it is heated to 50-60°C to kill pathogens and break down materials.
- Microbial Action: Microorganisms break down the waste into compost over several weeks.
- Maturation: The compost is left to mature before being used as soil fertilizer.
This process is highly efficient and can handle large volumes of waste, making it ideal for cities and businesses.
Benefits and Challenges of Commercial Composting
Benefits
- Reduces Landfill Waste: Diverts organic waste from landfills, reducing methane emissions.
- Produces High-Quality Compost: Creates nutrient-rich compost for agriculture and landscaping.
- Handles a Wide Range of Materials: Can process items that cannot be composted at home.
Challenges
- Requires Infrastructure: Depends on the availability of industrial composting facilities.
- Consumer Awareness: Many people are unaware of how to properly dispose of commercially compostable items.
- Cost: Setting up and maintaining commercial composting facilities can be expensive.
How to Dispose of Commercially Compostable Products
To ensure commercially compostable products are properly processed, follow these steps:
Check Labels: Look for certifications like “Commercially Compostable” or “Industrial Compostable” on the packaging.
Separate Waste: Keep compostable items separate from regular trash and recycling.
Use Designated Bins: Dispose of compostable products in bins provided by your local waste management service.
Support Local Facilities: Advocate for more commercial composting facilities in your area.
FAQs
Can I compost commercially compostable items at home?
No, commercially compostable items require the high temperatures and conditions of industrial facilities to break down properly.
How long does it take for commercially compostable items to decompose?
In industrial composting facilities, commercially compostable items typically decompose within 3-6 months.
Are commercially compostable products better for the environment?
Yes, they reduce landfill waste and produce nutrient-rich compost, making them a more sustainable option.produce
What happens if commercially compostable items end up in landfills?
They may not break down properly and can contribute to methane emissions, so proper disposal is essential.
Where can I find commercial composting facilities?
Check with your local waste management service or search online for facilities near you.
Conclusion
Commercially compostable products are an essential part of sustainable waste management. They are designed to break down efficiently in industrial composting facilities, reducing landfill waste and creating valuable compost. By understanding what commercially compostable means and how to properly dispose of these products, we can all contribute to a greener, more sustainable future.
