What is Bioplastic and PLA?

Our so gud™ PLA bottles significantly advance sustainable packaging, addressing the need to reduce our environmental impact and dependency on fossil fuels. These 500ml bottles, including the cap and label, are made entirely from plant-based materials, such as sugarcane. By steering clear of toxic fossil-based plastics, we offer a cleaner and safer choice for consumers and the planet. so gud™ bottles embody eco-conscious values and ensure that we provide an efficient, biodegradable packaging solution to combat plastic pollution.

Why Bioplastics?

Unlike traditional plastic, bioplastics are derived from biobased sources, are often designed to be compostable, or offer both properties. Biobased materials come from renewable sources like starch, sugars, cellulose, lactic acid, and proteins, typically sourced from plants such as corn, beets, sugarcane, and potatoes. This sustainable sourcing significantly reduces the ecological footprint associated with plastics, as bioplastics are often designed to biodegrade or compost after use, minimizing waste.

Our choice to use PLA (Polylactic Acid) for so gud™ PLA bottles, a widely used bioplastic, exemplifies our commitment to eco-friendly production. PLA offers many of the same benefits as conventional plastics—without the long-lasting environmental damage. While "biobased" simply indicates a product's origin, many bioplastics are also compostable, meaning they break down into natural substances within composting environments. Using PLA, we are tapping into a durable, sustainable, and biodegradable material that aligns with our mission of providing eco-friendly alternatives in the beverage industry.

Understanding Biobased Plastics

Biobased plastics are derived from renewable resources, often replenished within a decade. This rapid renewal contrasts sharply with fossil fuel-based plastics, which rely on resources formed over millions of years. The inherent properties of bioplastics, like biodegradability and recyclability, make them an exciting alternative to conventional plastics. Today, nearly every type of plastic made from fossil fuels has a viable bioplastic counterpart, allowing us to produce products with a smaller carbon footprint and new disposal options, such as composting.

Bioplastics are becoming a cornerstone of the growing bioeconomy. This expanding sector has the potential to both drive economic growth and reduce resource depletion. Not only are bioplastics versatile, but they also allow for the development of innovative waste management practices. Here are the primary categories of bioplastics:

  1. Biobased, non-biodegradable plastics – Examples include biobased versions of PE, PP, and PET, as well as performance polymers like PTT and TPC-ET.
  2. Biobased and biodegradable plastics – Examples include PLA, PHA, and PBS, which can decompose under industrial composting conditions.
  3. Fossil-based, biodegradable plastics – Materials like PBAT, which are not biobased but offer biodegradability.

The Advantages of PLA (Polylactic Acid)

PLA stands out as one of the most commonly used bioplastics. It's particularly popular because it can be processed on the same manufacturing equipment used for traditional petrochemical-based plastics, making it easy to integrate into existing production systems. PLA is produced through the fermentation of starch-rich crops like sugarcane, corn, and wheat into lactic acid, followed by polymerization into PLA resin. This resin can be molded into various products, including bottles, caps, and labels, making it ideal for beverage containers.

Our choice of so gud™ PLA aligns with our commitment to safe, natural materials. Our so gud™ PLA is also non-GMO, underscoring our dedication to health-conscious and environmentally safe sourcing. PLA's versatility enables it to be customized for various applications, from food packaging to medical uses.

PLA: A Promising Future

PLA has quickly gained prominence as one of the most promising bioplastics. With physical properties similar to fossil-based plastics, PLA can be used in a wide range of applications, including packaging, bottles, and even medical products. PLA's structure allows it to be processed on existing manufacturing equipment, reducing the need for significant industrial changes. This compatibility makes it an attractive choice for industries looking to make environmentally responsible choices without incurring high conversion costs. 

PLA is primarily sourced from crops like corn and sugarcane, which are converted to lactic acid through fermentation and then polymerized into PLA. The resulting material is durable, stable, and, if necessary, compostable under industrial conditions. While its low melting point limits its use for high-heat applications, PLA continues to be developed and refined to overcome such constraints.

PLA's applications extend far beyond packaging. It has been successfully used in medical and pharmaceutical settings for devices such as screws, plates, and implants that are resorbed by the body. Additionally, PLA nanoparticles are being studied as drug carriers and MRI contrast agents. This versatility illustrates PLA's potential as a valuable material in multiple sectors, from food packaging to healthcare.

The Urgent Need to Reduce Plastic Pollution

The environmental impact of conventional plastic is undeniable. Here are some critical statistics:

  • 73% of beach litter worldwide consists of plastic.
  • 38 million plastic bottles are discarded annually in U.S. landfills.
  • The amount of plastic waste discarded each year is enough to circle the Earth four times.
  • 24 million liters of oil are used to produce the billions of plastic bottles consumed globally.
  • One million seabirds and 100,000 marine mammals die each year from plastic pollution in our oceans.
  • Plastic bottles can take up to 700 years to decompose.

These staggering figures emphasize the importance of adopting sustainable alternatives to single-use plastic. At so gud™, we envision a future where environmentally responsible packaging options like bioplastics replace fossil-based plastics. By choosing so gud™ PLA bottles, consumers are not only enjoying a quality product but are also joining the movement toward a cleaner, healthier planet.

Environmental Benefits of PLA Bottles

  1. Reduced Carbon Footprint
  2. PLA production has a significantly lower carbon footprint than fossil-based plastics. Since PLA is made from renewable sources, its production process involves less carbon dioxide emission, which helps mitigate climate change.
  3. Non-Toxic Composition
  4. PLA is free from harmful chemicals often found in conventional plastics, such as BPA and phthalates, which can leach into food and beverages. Using non-toxic, plant-based PLA helps safeguard consumers' health while ensuring product safety.
  5. Biodegradability and Compostability
  6. PLA's compostable properties allow it to break down into natural substances in industrial composting environments. This means that at the end of its life, PLA can decompose into carbon dioxide, water, and biomass without polluting the soil or water.
  7. Supports the Bioeconomy
  8. As the demand for bioplastics grows, it contributes to the bioeconomy—a sustainable economic model based on renewable resources. This shift has the potential to generate new job opportunities and reduce dependency on finite fossil resources.

How PLA Compares with Other Plastics

Here’s a comparison of PLA with other common plastics—PET, HDPE, and PP—illustrating how PLA offers a sustainable advantage.
