Biodegradable vs. Compostable Printing: Key Differences

Explore the differences between biodegradable and compostable printing materials, their environmental impacts, and suitable applications for businesses.

Biodegradable and compostable printing materials are often confused, but they serve different purposes. Here’s a quick breakdown:

  • Biodegradable materials: Break down naturally with microorganisms over months or years. May leave residues like microplastics and don’t always require specific conditions.
  • Compostable materials: Fully decompose into non-toxic components (like water and biomass) within 90-180 days in industrial composting facilities. Require controlled conditions like heat, humidity, and aeration.

Quick Comparison

Characteristic Biodegradable Materials Compostable Materials
Raw Materials May include petroleum-based additives Typically plant-based (e.g., corn, sugarcane)
Breakdown Time Months to years 90-180 days under proper conditions
End Result May leave microplastics or residues Fully decomposes into soil-enriching elements
Certification Few or no standards Requires certifications (ASTM D6400, EN 13432)
Disposal Method Regular waste streams Needs industrial composting facilities
Environmental Impact May release methane in landfills Enriches soil when composted correctly

Businesses should choose based on their needs, disposal infrastructure, and environmental goals. Compostable options are ideal for food-related or zero-waste projects, while biodegradable options work for broader use cases but may have higher environmental risks.

Basic Differences: Biodegradable vs. Compostable

Biodegradable Materials Explained

Biodegradable materials break down with the help of microorganisms, moisture, and oxygen. They can decompose in different environments, but the process may take anywhere from a few months to several years. For example, biodegradable inks often include petroleum-based resins with additives to speed up the process[2], while biodegradable papers rely on natural fibers for quicker breakdown.

A biodegradable plastic film used in printing might degrade within 3-6 months under ideal conditions. However, in a landfill, it could last much longer[1]. Even when these materials break down, they may leave behind microplastics or other residues. In comparison, compostable materials require specific conditions to fully decompose.

Compostable Materials Explained

Compostable materials need controlled settings to break down completely. These settings are typically found in industrial composting facilities, where specific conditions are maintained:

Requirement Specification
Temperature 50-60°C (122-140°F)
Environment Controlled humidity
Process Proper aeration
Breakdown Period 90-180 days
Certification ASTM D6400 or EN 13432

One example is Burton’s Biscuit Company, which uses compostable packaging made from wood pulp and corn starch. This material, certified to EN 13432, decomposes within 26 weeks in industrial composting facilities. By adopting this approach, the company has reduced its plastic use by 61 tonnes per year[4]. Such certifications ensure compostable materials meet strict standards, making them an attractive option for businesses aiming to minimize waste.

Side-by-Side Comparison

Here’s a quick look at how biodegradable and compostable materials differ:

Characteristic Biodegradable Materials Compostable Materials
Raw Materials May include petroleum-based components with additives Primarily plant-based (corn, sugarcane, cellulose)
Breakdown Time Months to years 90-180 days under proper conditions
End Result May leave residues like microplastics Fully decomposes into non-toxic elements
Certification Few or no standards Requires certifications (ASTM D6400, EN 13432)
Disposal Method Can go into regular waste streams Needs industrial composting facilities
Environmental Impact May release methane in landfills Enriches soil when composted correctly

The main difference lies in the decomposition process. Biodegradable materials can break down in a variety of environments but might leave harmful residues. Compostable materials, on the other hand, are designed to decompose completely under specific conditions, leaving nothing toxic behind[6]. This makes compostable options especially appealing for zero-waste goals and businesses with access to industrial composting systems.

Effects on the Environment

The environmental impact of biodegradable and compostable materials sets them apart even further, especially when considering their breakdown processes, production, and chemical effects.

Breakdown Process and Results

Biodegradable materials decompose naturally but often under anaerobic conditions in landfills. This can lead to the release of methane – a greenhouse gas far more potent than CO2 – and leave behind microplastics or toxic residues[1]. In contrast, compostable materials, when processed in dedicated composting facilities, fully break down and contribute to soil health by enriching it with nutrients[1][3].

Production Requirements

Compostable materials are usually made from renewable sources like corn, cassava, and sugar cane[2]. A prime example is PLA (Polylactic Acid), which is created by fermenting plant starch into lactic acid. This process results in a lower environmental impact:

Production Aspect Environmental Impact
Raw Materials Sourced from renewable plants
Energy Usage Reduced carbon emissions compared to plastics
Resource Consumption Limited reliance on non-renewable resources
Waste Generation Produces less manufacturing waste

Biodegradable materials, however, can be derived from a wider range of sources, including petroleum-based plastics with added chemicals[1]. While they may use fewer resources than traditional plastics, their overall environmental impact is higher compared to compostable options[2].

Chemical Impact

The chemical differences during decomposition are also notable. Biodegradable materials can emit methane, release microplastics, and leach harmful additives. Certified compostable materials, on the other hand, break down into water, CO2, and biomass without leaving harmful residues[1][3].

Research into industrial composting standards shows that certified compostable materials must convert at least 90% of their mass into CO2, water, and biomass within 180 days to meet certification requirements[8].

Business Uses and Applications

Choosing the right material can help reduce waste and meet specific project requirements. These decisions tie into the earlier discussions on material properties and production methods.

When to Use Biodegradable Materials

Biodegradable materials are ideal for projects where durability is needed but eventual breakdown is planned. For instance, Dunkin’ Donuts successfully transitioned to biodegradable options in 2022, replacing nearly 1 billion foam cups with eco-friendly alternatives[1].

Here are some common uses for biodegradable materials:

Application Benefits Examples
Marketing Materials Long-lasting quality Brochures, catalogs
Shipping Materials Strong and reliable Mailers, protective wraps
Event Signage Resistant to weather Banners, posters
Product Packaging Maintains structure Non-food containers

When to Use Compostable Materials

Compostable materials are better suited for food-related uses or items that may come into contact with organic waste. These materials fully break down in industrial composting facilities within 90-180 days[1].

Typical applications include:

  • Restaurant Takeout: Containers and utensils that can be composted along with food scraps.
  • Grocery Packaging: Produce bags and wraps that are safe for composting.
  • Event Catering: Disposable plates, cups, and utensils that meet eco-friendly standards.
  • Agricultural Products: Items like mulch films and plant containers designed to decompose naturally.

Material Selection Guide

A study found that 64% of consumers are willing to pay more for sustainable packaging, making material choice a key business decision[9].

To select the best option, keep these factors in mind:

  1. Usage Environment
    Think about where and how the material will be used. For example, compostable materials may not hold up well in humid conditions.
  2. Disposal Infrastructure
    Check local waste management systems. If there aren’t commercial composting facilities nearby, biodegradable materials might be a better fit.
  3. Cost Considerations
    Compare the upfront cost of materials with potential long-term gains. Market trends show these options are becoming more competitive over time[7].

Disposal and Certification Issues

As eco-friendly printing gains popularity, businesses face challenges with limited infrastructure and navigating complex certifications. One of the main hurdles is the lack of facilities: only 185 full-scale composting sites in the U.S. accept compostable packaging, and less than 5% of such materials are processed correctly[7].

Disposal Systems and Access

Many areas lack the industrial composting facilities necessary for proper decomposition[1].

Challenge Impact Solution
Limited Facility Access Materials end up in landfills Partner with specialized waste services
Contamination Risk Reduces recycling effectiveness Establish strict sorting protocols
Inconsistent Local Rules Disposal methods vary widely Research area-specific requirements
Collection Gaps Improper material handling Set up private collection programs

Programs like Pela 360 offer innovative solutions. Since 2022, Pela 360’s mail-back program has kept over 100,000 units of compostable phone cases out of landfills by providing a closed-loop system[7]. However, disposal isn’t the only concern – ensuring materials meet proper standards is just as critical for avoiding legal risks and maintaining customer confidence.

Material Standards and Claims

Certifications play a key role in validating environmental claims and guiding material choices for sustainable printing. Here are some of the most recognized standards:

  1. ASTM D6400 Certification
    This North American standard outlines the requirements for labeling materials as compostable in municipal and industrial facilities[1].
  2. EN 13432 Certification
    Widely used across Europe, this standard ensures that materials meet strict compostability requirements[2].
  3. BPI Certification
    The Biodegradable Products Institute provides third-party verification for compostable products in North America, helping businesses avoid misleading claims[1].

"Compostable materials must break down within 180 days in industrial composting facilities to meet certification requirements[9]."

To maintain compliance and trust, businesses should verify certifications through official databases, supplier documentation, independent testing, and regular audits.
