Understanding Bio PLA

Bio PLA, or polylactic acid, is a biodegradable and compostable polymer that has gained popularity in recent years due to its sustainability and environment-friendly properties. This material is produced from renewable resources such as corn starch, sugarcane or other natural plant-based sources. It is then used to make a variety of products, including packaging materials, disposable utensils, and medical implants. The production of Bio PLA starts with the extraction of natural sugars from plant-based sources, which are fermented to produce lactic acid. The lactic acid is then polymerized to form long chains, which are used to make Bio PLA. The production process is more sustainable compared to traditional petrochemical-based polymers, which require the use of non-renewable resources and release harmful emissions into the environment.

Top 10 Benefits of Bio PLA over alternatives:

Corn Bio PLA has several advantages over traditional plastics and other biodegradable materials. Here are ten ways in which it is better than alternatives:

1. Renewable and Sustainable: It is made from renewable resources such as corn starch or sugarcane, making it a more sustainable alternative to petroleum-based plastics

2. Biodegradable: It is biodegradable and breaks down into natural compounds such as carbon dioxide and water, unlike traditional plastics which can take hundreds of years to degrade. Its biodegradability and compostability make it a sustainable choice for a wide range of products

3. Low Carbon Footprint: The production requires less energy and generates fewer greenhouse gas emissions than traditional plastics

4. Versatile: It can be used in a wide range of applications, from food packaging to textiles to 3D printing filament

5. Safe for Food Contact: It is safe for food contact, making it an ideal material for food packaging and disposable cutlery

6. Compostable: It can be composted in industrial composting facilities, reducing waste and contributing to a circular economy

7. Lightweight: It is lighter than traditional plastics, reducing transportation emissions and making it a better option for shipping and handling

8. Odourless: It is odourless and does not leach harmful chemicals, making it a safer option for consumer products

9. Recyclable: It can be recycled into new Bio PLA products, reducing waste and promoting a circular economy

10. Cost-Effective: While it may be more expensive than traditional plastics, the cost will decrease as production methods improve and demand increases. Additionally, its environmental benefits can lead to cost savings in waste management and energy use


However, there are some limitations to the use of Bio PLA:

1. Firstly, the production of Bio PLA requires significant amounts of energy and resources, including water and land, which suggests that while it is more sustainable than traditional plastics, it has its share of environmental impact

2. Its composting requires specific conditions, including temperature and humidity, which may not be available in all environments, making it unsuitable for all systems

3. The cost is currently higher than traditional plastics, which can limit its adoption in some industries. However, as technology advances and production processes become more efficient, the cost is expected to decrease, making it a more viable alternative to traditional plastics

4. Sometimes, PLA is too fragile and is not compatible with many packaging manufacturing processes. Therefore, it needs to be strengthened with additives



While there are some limitations to the use of Bio PLA, such as its production impact and higher cost, its potential to reduce environmental pollution and provide sustainable alternatives makes it a valuable addition to the materials industry. To conclude, it is a promising alternative to traditional petrochemical-based polymers as its advantages far outweigh the limitations.
