Top 10 Benefits of Compostable Clamshell Containers

Aug 16, 2025

1. What Are Compostable Clamshell Containers?

Compostable clamshell containers are an eco-friendly choice for food packaging. They have a hinged lid and are designed to replace styrofoam and plastic boxes in the food industry. They are made from plant-based and renewable materials such as sugarcane bagasse, wheat straw fibre, cornstarch (PLA), or bamboo fibres.

Compostable containers are a great alternative to plastics. Regular plastics can stay in landfills for over 400 years. In contrast, certified compostable containers break down into nutrient-rich soil in just 90 to 180 days. They meet strict standards like ASTM D6400 or EN 13432 and are often verified by groups like BPI. This process leaves no harmful microplastics behind.

These containers are widely used by restaurants, catering services, food trucks, and takeaway businesses as part of their sustainability programs. They are suitable for both cold foods and hot meals (when made from durable fibre materials such as bagasse) and are valued by eco-conscious consumers who want packaging that is safe, renewable, and aligned with global plastic ban regulations.

6. Environmental Impact & Sustainability

  • Compostable plates are often promoted as eco-friendly plates for good reason — their environmental footprint is typically far lighter than that of traditional plastic or foam disposables. But to truly understand their value, it’s important to look at measurable impacts, data-backed claims, and the broader sustainability context.

    6.1 How They Reduce Carbon Footprint

    One of the main advantages of compostable plates is the use of renewable, plant-based, or waste-derived raw materials such as bagasse, bamboo, or agricultural by-products. These resources regenerate naturally and lower our dependence on fossil fuels, which are heavily used in manufacturing conventional plastics.

    Life Cycle Assessments (LCA) conducted by independent laboratories frequently show that compostable plates generate significantly lower greenhouse gas emissions throughout their lifespan — from raw material harvesting to disposal — compared to single-use plastic or foam alternatives.

    For example:

    • Bagasse compostable plates can utilise waste sugarcane fibre that would otherwise be burned, preventing associated CO₂ emissions.

    • Bamboo compostable plates grow rapidly without pesticides, absorbing more CO₂ during cultivation than most hardwoods.

    The combined effect is a measurable reduction in carbon footprint over the product’s life cycle.

    6.2 Waste Management Advantages

    Compostable plates align strongly with circular economy principles by turning what was once waste into nutrient-rich compost that supports soil health. When disposed of correctly through home or industrial composting, they:

    • Return valuable organic matter to the earth instead of becoming long-term waste.

    • Reduce landfill volumes, helping municipalities cut waste management costs.

    • Minimise plastic pollution in rivers and oceans, as they don’t persist for centuries like petroleum-based plastics.

    By diverting organic waste away from landfills, compostable plates also reduce methane emissions — a greenhouse gas over 25 times more potent than CO₂ — generated from decomposing food and organic matter under anaerobic landfill conditions.

    6.3 Research & Data Support

    The environmental benefits are supported by credible, third-party research:

    • United Nations Environment Programme (UNEP) 2022 Report: Transitioning from conventional plastics to compostable materials in appropriate applications could reduce global plastic pollution by up to 70% by 2040.

    • US Environmental Protection Agency (EPA) Data: Compostable food service packaging helps divert significant volumes of organic waste from landfill streams, directly lowering methane emissions and contributing to municipal climate action goals.

    Combined, these findings underline that when sourced responsibly, used in the right contexts, and disposed of properly, eco-friendly disposable plates can be a powerful tool in reducing environmental impact.

What's the Difference Between Compostable and Biodegradable?
In a world increasingly focused on sustainability, you often hear terms like "compostable" and "biodegradable" used interchangeably. However, there are crucial differences between the two that can significantly impact your choices, especially when it comes to products you use every day, like disposable tableware or disposable plates. Understanding these distinctions is key to making truly eco-conscious decisions.

Understanding "Biodegradable"

Let's start with biodegradable. At its core, "biodegradable" simply means that a material can be broken down by microorganisms (like bacteria and fungi) into natural elements such as water, carbon dioxide, and biomass. This process can happen naturally in various environments, including soil, water, or even landfills. Sounds great, right? Here's the catch: the term "biodegradable" doesn't specify how long it takes for a material to break down, nor does it guarantee that it will break down into harmless components. A plastic bag might be labeled "biodegradable," but it could take hundreds of years to decompose, potentially leaving behind microplastics that pollute the environment. So, while a 100% biodegradable plate might sound ideal, without further context, it doesn't tell you much about its environmental impact. It could still contribute to landfill waste for a very long time.

Diving into "Compostable"

10" Compostable Round Plates – Repurpose Now, let's talk about compostable. This term is much more specific and holds a higher standard for environmental responsibility. For a product to be labeled "compostable," it must meet strict requirements for breaking down into organic matter, water, and carbon dioxide within a specific timeframe, under specific conditions. Think of it this way: compostable plates and cutlery are designed to decompose fully and safely into nutrient-rich compost, which can then be used to enrich soil. This process typically requires an industrial composting facility, where conditions like temperature, moisture, and aeration are carefully controlled to accelerate decomposition. Here are the key characteristics of compostable products:
  • Breaks Down Completely: They fully disintegrate into natural elements, leaving no toxic residues.
  • Specific Timeframe: They must break down within a defined period (e.g., 90-180 days) as per certification standards.
  • Requires Specific Conditions: Most compostable items, like sugarcane compostable plates or compostable clamshell containers, need the controlled environment of an industrial composting facility to break down effectively. Home composting can be more challenging for some products, but some are certified for that too.
  • Creates Valuable Compost: The end product is a nutrient-rich material that improves soil quality.
When you see products like compostable bowls and plates, compostable food trays, you can be confident that they are designed to return to the earth in a beneficial way, provided they are disposed of correctly in a composting stream.

Compostable vs. Biodegradable: A Quick Comparison

Feature Biodegradable Compostable
Definition Breaks down by microorganisms into natural elements. Breaks down into organic matter, water, and CO2, becoming nutrient-rich compost.
Timeframe for Breakdown Not specified; can take anywhere from weeks to hundreds of years. Specific timeframe, typically 90-180 days under controlled conditions.
Residual Materials May leave behind harmful residues or microplastics. Leaves no toxic residues; becomes beneficial compost.
Required Conditions Can break down in various environments (soil, water, landfill); often uncontrolled. Requires specific, controlled conditions (e.g., industrial composting facilities).
Environmental Benefit Less clear; can still contribute to long-term pollution depending on breakdown. Clear; contributes to soil health and reduces landfill waste by creating new resources.
Certification Generally no specific certification for breakdown time or residue. Often certified by organizations (e.g., BPI, EN 13432) ensuring strict standards are met.

Why the Distinction Matters for Your Choices

Understanding the difference is crucial, whether you're looking for wholesale disposable plates for an event or simply choosing disposable plates and cups for your home.
  • True Environmental Impact: Opting for compostable disposable plates ensures that your waste can become a valuable resource rather than just adding to landfills. This is particularly important for items like compostable holiday plates where waste generation can be high.
  • Avoiding "Greenwashing": The term "biodegradable" can sometimes be used to mislead consumers into thinking a product is more eco-friendly than it is. "Compostable," especially when accompanied by certifications (like BPI certification in North America or EN 13432 in Europe), offers a much clearer picture of a product's end-of-life characteristics.
  • Supporting Circular Economy: Choosing truly compostable items, like compostable salad containers or compostable clamshells, actively participates in a circular economy where waste is minimized and resources are regenerated.

Can You Heat Up Compostable Containers?
In today's world, where eco-friendly food containers are becoming the norm, you've probably wondered: can I safely heat up my compostable containers? It's a great question, especially when you're dealing with leftovers or warming up takeout. Let's dive into the practicalities of heating compostable food containers, including popular options like compostable take out containers, compostable clamshell containers, and bagasse takeaway containers.

The Short Answer: It Depends!

Not all compostable containers are created equal when it comes to heat. Their ability to withstand heat depends largely on the material they're made from. Generally, these containers are designed for serving food, and some are more robust than others when it comes to temperature fluctuations.

Rectangle cake compostable container plateRCP-101-5Understanding Different Compostable Materials and Heat

When you see terms like biodegradable to go containers or compostable containers for food, it's important to know what materials they typically refer to. Here's a breakdown:
  • Bagasse (Sugarcane Fiber): This is one of the most common and heat-tolerant materials for compostable takeaway containers. Bagasse takeaway containers are made from the pulp residue left after sugarcane is processed. They are often microwave-safe and can handle hot foods and liquids well. Many compostable clamshells and compostable soup containers are made from bagasse, making them a great choice for hot meals. You can often reheat food in these without issue, but always check the manufacturer's recommendations.
  • PLA (Polylactic Acid): PLA is a plant-based plastic derived from renewable resources like corn starch. While it's great for cold applications like salads or desserts, PLA has a lower heat tolerance. It can deform or melt at higher temperatures (around 105-140°F or 40-60°C). This means PLA-lined compostable take out containers or clear PLA compostable soup containers are generally not suitable for microwaves or ovens. They're perfect for cold meals but should be avoided for reheating.
  • Recycled Paperboard with Linings: Some eco-friendly food containers are made from recycled paperboard, often with a compostable lining to prevent leaks. The heat resistance here depends on the lining material. If it's a PLA lining, the same heat limitations apply. If it's a different, more heat-resistant compostable lining, it might tolerate warmer foods, but microwaving is usually not recommended unless explicitly stated.

Compostable Container ClamshellKey Considerations When Heating Compostable Containers

To ensure safety and maintain the integrity of your eco-friendly takeout containers, keep these points in mind:
  1. Always Check Manufacturer Guidelines: This is the most crucial step! Reputable manufacturers, like us at Keyi, will clearly indicate whether their compostable containers are microwave-safe or suitable for hot foods. Look for symbols or text on the product packaging or on the product description page.
  2. Microwave vs. Oven: Generally, if a compostable container can handle heat, it's usually designed for microwave use, not conventional ovens. Ovens reach much higher temperatures that most compostable materials cannot withstand without deforming, melting, or even posing a fire risk.
  3. Hot Liquids: While many compostable soup containers are designed for hot liquids, rapid temperature changes or prolonged exposure to extremely hot liquids can sometimes affect their integrity. Be mindful, especially with very hot soups or coffees.
  4. Food Temperature: The temperature of the food you're placing in the container matters. Freshly cooked, very hot food is different from reheating cold leftovers. Bagasse containers, for instance, are generally good for hot, fresh food.
  5. Not for Cooking: Remember, biodegradable containers for food are designed for serving and holding food, not for cooking. Never attempt to cook food directly in these containers.

Why Choose Compostable and Biodegradable Containers?

Even with these heating considerations, the benefits of choosing biodegradable takeout containers wholesale or compostable clamshells far outweigh the limitations. They offer a sustainable alternative to traditional plastics, reducing landfill waste and minimizing environmental impact. When properly composted, these materials break down into nutrient-rich soil, completing a truly circular economy. At Keyi, we are committed to providing high-quality eco friendly food containers wholesale that meet your needs while prioritizing environmental responsibility.
