Corn starch Plastic Biodegradable

Polylactic acid (PLA), a plastic substitute made from fermented plant starch (usually corn), is fast becoming a popular alternative to traditional petroleum-based plastics.
Cornstarch pens are made by a number of manufacturers in the EU and China using Mater-Bi or PLA (polylactic acid - a polymer made from lactic acid, fermented from the glucose found in cornstarch) and other revolutionary biodegradable materials made from cornstarch. The biodegradability of the pen body is comparable to cardboard when composted and there are no toxic or metallic residues. Longer-lasting products such as cups and rulers can also be made from corn starch, which takes longer to break down under composting conditions.

Corn starch products such as pens, rulers, and cups can be made into oil-based plastic substitutes by using renewable agriculturally derived starches to make bioplastic polymers. Cornstarch plastic products look and feel like regular plastics, but they are 100% biodegradable and compostable. Corn starch products are more popular mainly because:

They are made from renewable plant materials
They replace fossil fuel-based products
They are theoretically recyclable if the system is actually in place
They are biodegradable and compostable at the end of their useful life

Biodegradable & Compostable Resin Biodegradable & Compostable Bags

These resins can be utilized in various industries, including packaging, agriculture, textiles, and consumer goods, offering versatile applications.

These resins align with the principles of a circular economy by promoting the creation, use, and regeneration of materials in a closed-loop system.

They are generally non-toxic and safe for use in food packaging and medical applications, reducing health risks associated with conventional plastic use.

Biodegradable and compostable resins minimize soil, water, and air pollution by circumventing the accumulation of persistent plastic waste in ecosystems.

By facilitating the decomposition of products made from these resins, there's a significant reduction in waste accumulation in landfills and oceans.

Their ability to break down naturally ensures that these materials won't persist in the environment for centuries, unlike traditional plastics.

Biodegradable and compostable resins can often be processed using existing equipment, making their integration into current manufacturing systems feasible.

These resins break down naturally into simpler, non-toxic components, significantly reducing their environmental impact compared to conventional plastics.

As they're derived from renewable sources, biodegradable resins reduce our dependence on finite fossil fuel resources, contributing to a more sustainable future.

Biodegradable resins are primarily composed of organic materials such as cornstarch, sugarcane, or vegetable

They possess the ability to degrade through biological processes when exposed to the environment, such as soil, water, or microbial action, returning to nature without causing harm.

Compostable resins degrade into organic matter under controlled conditions, turning into nutrient-rich compost that can nourish soil and plants

Pros and Cons of Corn Starch Packaging

While cornstarch is more environmentally friendly than plastic, it has its own pros and cons.
Advantages of Corn Starch
Cornstarch packaging is a more environmentally friendly alternative to plastic and polystyrene foam due to the following advantages:
Renewable: corn is a staple crop that is abundant and readily available.
Biodegradable: Corn starch naturally decomposes and breaks down into its basic elements without harming the environment as other plant materials do.
Compostable: Cornstarch packaging meets the criteria for compostable plastics and can be converted into environmentally friendly fertilizer in industrial composting facilities.
Recyclable: Cornstarch packaging can be recycled at specialized facilities. The material extracted from it can be used to make other environmentally friendly products, such as plates or cups.
Non-toxic: Contains no harmful chemicals such as dioxins or polyvinyl chloride.
Reduced waste and pollution: Corn starch is biodegradable and compostable, so it does not take up space in landfills or release harmful substances into the environment.
Low Carbon Emissions: Corn starch production emits fewer greenhouse gases than traditional plastic production.
Oil and fat resistant: suitable for holding oily foods.
UV Resistant: Reliable for products that need to be protected from UV radiation.
Low flammability: less risk of fire when using cornstarch packaging.
High aroma barrier: prevents food from losing its aroma or being contaminated with unpleasant odors.
Suitable for printing: companies can put branded labels on corn starch packaging without harming the environment, while still providing a high-quality customer experience.
Increased marketability and brand awareness: Sustainability-conscious consumers are attracted to companies that adopt environmentally friendly practices.

Disadvantages of Corn Starch

Cannot be composted at home: cornstarch packaging can only decompose in the hot and humid environment of a commercial composting facility. Therefore, it cannot be composted in home compost piles or garbage cans.
Recycling contamination: improper disposal can lead to contamination within the recycling stream.
CUSTOMER BEHAVIOR: Most people are unfamiliar with cornstarch packaging and will not properly compost or dispose of the material. This will result in cornstarch packaging ending up in landfills or contaminating other recycling streams.
Methane Gas Emissions: If decomposed in a landfill, cornstarch packaging releases methane, a more potent greenhouse gas than carbon dioxide.
Acidic: Composting large amounts of corn starch can make soil acidic.
Limited Infrastructure: Because cornstarch is so new as a packaging material, there is currently only a small amount of infrastructure to support its manufacture, composting, or recycling.
Potential impact on food production: Corn starch comes from a staple crop and overuse of packaging could disrupt the global food supply chain.
High production costs: Corn starch packaging is expensive and impractical for some businesses, especially SMEs and start-ups.
While improvements are being made to address these issues, awareness-raising is the best way to address them.
With greater awareness of this packaging material, consumers will have a better understanding of how to properly dispose of cornstarch packaging, preventing more cornstarch from entering our landfills.
