### 1. How does PLA plastic break down?
PLA plastic, also known as polylactic acid, is a type of biodegradable plastic made from renewable resources such as corn starch or sugarcane. When disposed of in the environment, PLA plastic is broken down by the naturally occurring microorganisms in the soil or compost. These microorganisms secrete enzymes that break down the molecular structure of the PLA plastic into simpler compounds like water, carbon dioxide, and biomass. This process is known as biodegradation.
### 2. What are the benefits of using biodegradable PLA plastic for packaging?
One of the main benefits of using biodegradable PLA plastic for packaging is its environmental friendliness. Unlike traditional plastics made from petroleum-based resources, PLA plastic is made from renewable resources and can be composted, reducing the amount of waste that ends up in landfills. Additionally, the production of PLA plastic generates fewer greenhouse gas emissions compared to traditional plastics, making it a more sustainable option for packaging.
### 3. How long does it take for PLA plastic to decompose in the environment?
The biodegradation time of PLA plastic varies depending on the environmental conditions such as temperature, humidity, and microbial activity. In industrial composting facilities where conditions are optimal for biodegradation, PLA plastic can break down within a few months. In home composting settings, it may take longer for PLA plastic to decompose, ranging from 6 months to 2 years. When disposed of in the natural environment, PLA plastic may take several years to break down due to lower microbial activity and limited oxygen availability.
In conclusion, biodegradable PLA plastic for packaging works by breaking down into simpler compounds through the action of microorganisms in the environment. Its benefits include environmental friendliness and reduced greenhouse gas emissions compared to traditional plastics. The time it takes for PLA plastic to decompose varies depending on the environmental conditions, but in ideal conditions, it can break down within a few months to a few years.
