How is biodegradable packaging made?

Published in Sustainable Packaging 2 mins read

Biodegradable packaging is primarily manufactured from renewable, plant-based materials such as wheat or corn starch.

The Core Materials of Biodegradable Packaging

Unlike conventional plastics derived from fossil fuels, biodegradable packaging marks a significant shift towards more environmentally friendly alternatives. This type of packaging is fundamentally made from plant-based materials, leveraging the natural properties of organic matter to create sustainable solutions.

Key materials often include:

  • Wheat starch: A readily available byproduct from wheat processing.
  • Corn starch: Derived from corn, offering a versatile base for various packaging types.

For instance, companies like Puma have already integrated packaging made from these plant-based materials into their operations, demonstrating a practical application of this technology.

Conditions Required for Biodegradation

While biodegradable packaging is designed to break down naturally, it's crucial to understand that specific environmental conditions are necessary for this process to occur effectively. These conditions facilitate the microbial activity that leads to decomposition.

For the packaging to properly biodegrade:

  • Temperature: Conditions need to reach 50 degrees Celsius.
  • Light Exposure: The material must be exposed to UV light.

It is important to note that these specific conditions are often not easily found in typical environments other than landfills. This highlights a challenge in ensuring that biodegradable packaging genuinely decomposes as intended outside of controlled industrial composting facilities or specific landfill environments.

Understanding Biodegradation Requirements

The following table summarizes the key components and conditions vital for the effective breakdown of biodegradable packaging:

Aspect Description
Primary Materials Plant-based, renewable resources (e.g., wheat or corn starch)
Temperature Needed Elevated temperatures of 50 degrees Celsius
Light Requirement Exposure to UV light
Optimal Environment Conditions most commonly met in landfills or industrial composting facilities, not always natural settings

Benefits and Real-World Considerations

The use of plant-based materials in biodegradable packaging offers a promising avenue for reducing plastic pollution and dependence on finite fossil resources. However, understanding the specific environmental requirements for its decomposition is critical. While the raw materials offer a sustainable start, the subsequent breakdown process relies heavily on achieving the necessary temperature and UV light exposure. This means that simply being labeled "biodegradable" does not guarantee rapid decomposition in all natural environments, often requiring specialized conditions.
