Advantages of Biodegradable Plastic

Reducing Pollution and Waste

One of the major advantages of biodegradable plastic is its ability to reduce pollution and waste. Unlike traditional plastic, which can take hundreds of years to decompose, biodegradable plastic breaks down much faster. This means that it doesn’t accumulate in landfills or pollute our oceans for extended periods of time. In fact, biodegradable plastic can completely degrade within a few months to a few years, depending on the specific material used. This not only helps to reduce the amount of plastic waste in our environment, but also decreases the harmful effects of plastic pollution on wildlife and ecosystems.

Conserving Energy and Resources

Another advantage of biodegradable plastic is its potential to conserve energy and resources. The production of traditional plastic involves the extraction of fossil fuels, such as oil and natural gas, which are non-renewable resources. In contrast, biodegradable plastic can be made from renewable resources, such as cornstarch or vegetable oil. Additionally, the manufacturing process of biodegradable plastic requires less energy compared to traditional plastic production. This means that by using biodegradable plastic, we can reduce our dependence on fossil fuels and minimize the environmental impact associated with their extraction and processing.

Protecting Marine Life

Biodegradable plastic also plays a crucial role in protecting marine life. It is estimated that over 8 million tons of plastic enter our oceans every year, causing significant harm to marine ecosystems. Traditional plastic can break down into smaller pieces known as microplastics, which are often mistaken for food by marine animals. These microplastics can accumulate in their digestive systems, leading to malnutrition, organ damage, and even death. By using biodegradable plastic, we can help to prevent this harmful cycle by ensuring that the plastic breaks down naturally and doesn’t pose a threat to marine life. Furthermore, biodegradable plastic reduces the need for single-use plastic items, such as bags and straws, which are commonly found in marine environments.

According to a study conducted by the World Wildlife Fund (WWF), biodegradable plastic has the potential to reduce plastic pollution by up to 80% compared to traditional plastic.
