How Does Biodegradable Plastic Work?
Biodegradable plastics are made from organic materials such as corn starch, sugar cane, potato starch, and corn oil. These materials are combined and processed to create a material that shares physical and chemical traits with traditional plastics. The difference is that the organic materials used in biodegradable plastics can be broken down by microorganisms in the environment.
When biodegradable plastic is disposed of in the environment, microorganisms in soil, water, or air start to break it down. These microorganisms, which include bacteria and fungi, use enzymes to break apart the material, resulting in the release of carbon dioxide, water, and biomass. This process is called biodegradation.
The rate at which biodegradable plastic decomposes depends on various factors, such as temperature, humidity, the presence of microorganisms, and exposure to sunlight. In controlled conditions, biodegradable plastics can take as little as three months to decompose. However, in natural conditions, the process might take longer.
Another way biodegradable plastics work is through composting. Composting is a process of breaking down organic materials into nutrient-rich soil, known as compost. Biodegradable plastics can be composted alongside other organic materials, such as food waste and yard trimmings. In a composting environment, biodegradable plastics break down faster, as the conditions are optimized for bacterial activity.
However, it's important to note that not all biodegradable plastics are created equal. Some biodegradable plastics are only capable of decomposing in industrial composting facilities, where conditions such as temperature, humidity, and bacteria concentration can be controlled. Others can biodegrade in home compost bins, while others can only biodegrade in specific environments, such as soil or water.
Biodegradable plastics offer a more environmentally friendly alternative to traditional plastics. They help reduce the accumulation of non-biodegradable waste in landfills and oceans, and they can be an essential part of eco-friendly packaging. However, it's essential to ensure that biodegradable plastics are disposed of correctly, according to the manufacturer's guidelines. Otherwise, they might not decompose correctly, leading to harm to the environment.
In conclusion, biodegradable plastic works through biodegradation or composting. The organic materials used in biodegradable plastics can be broken down by microorganisms in the environment, resulting in the release of carbon dioxide, water, and biomass. Biodegradable plastics offer a more eco-friendly alternative to traditional plastics, but it's crucial to ensure that they are disposed of correctly. By doing so, we can all contribute to a more sustainable environment for future generations.
