Biodegradability

The Problem with Biodegradability

Confusion about which products are legitimately biodegradable. Biodegradability

By definition, most chemicals are biodegradable because they’re capable of being broken down by the action of living things, such as microorganisms.

Biodegradability

However, there’s no universal definition or certification for the marketing claim “biodegradable”. The Federal Trade Commission (FTC) has issued general guidelines on what types of products qualify as legitimately biodegradable, and has even sued companies for unsubstantiated, misleading and/or deceptive use of the term on product labels.

Current FTC guidelines state that for marketers to make such a claim, an entire product or package should completely break down and return to nature within a “reasonably short period of time” after customary disposal. The FTC also states that marketers should not make unqualified claims of biodegradability for items destined for landfills, incinerators, or recycling facilities.

BioMass Packaging continues to conform to FTC guidelines for all products we sell and represent.

There’s a vast difference in how long it takes for different materials to break down

How quickly an item decomposes into the earth depends on its basic components, the percentage of its biodegrading materials, and where it is left to decompose.

In a perfect world:

A plastic toy would break down as quickly as a piece of birthday cake;

Substances would degrade into carbon dioxide and water;

Certain chemicals would not degrade into more dangerous substances, like the banned, toxic pesticide DDT. Which breaks down into DDE and DDD — more harmful than the original substance.

Decomposition rates of items in landfills are staggeringly slow due to the absence of sunlight, moisture and air exposure. Some rough estimates of the time it takes for certain products to completely break down in a landfill include:

Apple core: 1 to 2 months or longer, due to lack of microbes

Paper Bag: 1 month

Tin Can: 50 years

Aluminum Can: 80-200 years (if recycled, it can be reused within 6 weeks)

Plastic drinking bottles: hundreds of years (they consist of polyethylene terephthalate (PET))

Disposable Diapers: 550 years

Plastic Bags: up to hundreds of years

Plastic milk jug: 500 years

Glass: 1-2 million years (but if recycled, it can be reused within 6 weeks)

Styrofoam: never (no sign of ever breaking down)

The Solution

Start by reading labels and/or doing online research

For consumers to judge the viability of a biodegradable product claim, they can:

Start by reading the product label

Try to select products that are made of ingredients you recognize as natural

Look for manufacturers who clearly list all product ingredients

Choose products packaged in bioplastic over those in petroleum-based plastic

Do research online to further determine the biodegradability and compostability of certain products, and how long each product may take to break down completely. These would include food items, plastic resins, packaging materials, bags, and consumer products.

Also, a few third-party organizations that offer voluntary standards and labels to companies have created scientifically based, standards and certifications for compostability of certain materials.

Rely on third party certifications for accurate information

Companies voluntarily participate in third party certification programs. To assure their customers that their products behave as advertised. There are several independent organizations that offer certifications, such as:

The Biodegradable Products Institute (BPI) is a non-profit organization. That educates manufacturers and the public about biodegradability as it relates to composting bio-plastics materials. And other coatings and packaging that may go into commercial compost facilities. ASTM standards 6400 and 6868 and its Compostable label may be found on products such as garbage bags, service ware, and packaging.

Recycle everything possible

More than 30% of bulk municipal garbage collections consist of paper that could be remade into other paper products. About 70% of materials that are routinely disposed of in landfills could be recycled instead. Other materials like plastic, metal and glass can also be repurposed.

Recycling these materials can not only greatly reduce the amount of waste disposed in landfills, but preserve our limited sources of nonrenewable raw materials.

The Benefits of Biodegradability

There are multiple advantages to using and properly disposing of biodegradable and compostable products that:

Are non-toxic

Are better for the environment, dispersing very few greenhouse gases

Take less time to break down than other solid materials

Are made from biomass — organic compounds are completely renewable

Often require less than half as much energy to manufacture

Reduce our dependence on foreign countries’ fossil fuels

Reduce the costs of solid waste disposal

Divert waste from already overcrowded landfills, thereby reducing groundwater and air pollution via methane

Support local, sustainable businesses such as composters
