2. How is PLA compostable plastic sustainable?

3. Are there any limitations to the sustainability of PLA compostable plastic?

## Answers.

1. PLA compostable plastic, also known as polylactic acid, is a biodegradable and compostable polymer made from renewable resources such as corn starch or sugarcane. It is commonly used as an alternative to traditional petroleum-based plastics.

2. PLA compostable plastic is sustainable for several reasons. Firstly, it is derived from renewable resources, reducing the reliance on finite fossil fuels. Additionally, PLA biodegrades under certain conditions, breaking down into water, carbon dioxide, and organic matter, which can be used as soil nutrients. This reduces the amount of plastic waste in landfills and oceans, helping to minimize environmental impact.

3. While PLA compostable plastic has many sustainability benefits, there are also limitations to consider. PLA requires specific industrial composting facilities with controlled conditions to biodegrade properly. If PLA ends up in traditional landfill or marine environments, it may not break down as intended, potentially contributing to pollution. Furthermore, the production of PLA can still have some environmental impacts, such as the use of pesticides in growing the raw materials. It is important to consider the full life cycle of PLA compostable plastic to ensure its sustainability.
