​Using biodegradable plastic bags is an effective means of reducing the amount of plastic waste that is produced in the world. This is because these types of plastics can be regenerated after they have been broken down by microorganisms and other natural processes. These biodegradable plastics are also known to be more environmentally friendly than their non-biodegradable counterparts.

Non-biodegradable plastics vs biodegradable plastics

Whether you are a consumer, a policymaker, or a recycler, the question of biodegradable plastics vs. non-biodegradable plastics has a lot to do with your waste management strategy.

Non-biodegradable plastics are those that don't decompose naturally in the environment. These plastics often take a long time to decompose. This means they aren't suitable for composting. Some of them can also be hazardous to animals, as well as polluting soil and the oceans.

Biodegradable plastics are a group of plastics that break down in the environment, either through exposure to sunlight, air, and water, or through the action of microorganisms. Biodegradable plastics are often made from plant material, such as corn starch. Some of them are made from petroleum-based materials.

Biodegradable plastics can reduce the amount of waste that goes into landfills. However, they still require specific methods of disposal. If they are contaminated with heavy metals, for example, they may not be easily recyclable.

Microorganisms responsible for decomposition

Various kinds of microorganisms are known to be responsible for decomposing plastic biodegradable bags. However, the specific microbes involved in this process are not well defined. It is still a challenge to identify which organisms are responsible for degrading plastics and to understand the molecular mechanisms of their formation.

The marine environment is home to hundreds of millions of bacterial cells in a single gram of wet sediment. Plastics are the major source of anthropogenic debris that enter the oceans. These plastics have evolved within a relatively short evolutionary period. During this time, they have become adapted to normal environmental conditions. Plastics are designed to be used by humans. However, their physicochemical properties can change at extreme environmental conditions.

Plastics are composed of long chains of polymer molecules. Microbial organisms alter the chemical structure of the plastic through enzymatic activity. Some of these organisms break the polymer chains into smaller biomolecules. Some of them also use excreted wastes to degrade the polymer.

Impact of regulation on consumption of biodegradable plastic bags

Despite the obvious benefits of switching from conventional plastics to biodegradable ones, there are also trade-offs. These can include consumer differences, implementation and enforcement issues, and the actual effects of the policy.

A study in Ireland demonstrates that regulations based on a surcharge on plastic bags are effective in reducing consumption. Despite the cost of the levy, it was found that consumers were more likely to switch to plastic bags from paper alternatives, reducing their average monthly consumption by about 0.2 million bags.

In Botswana, bags with a thickness below 30 microns are banned. This was followed by taxes on the bags, which have shown to be effective at reducing consumption. The combination of these two measures resulted in a 50% drop in the average number of plastic bags used.

This effect is also visible in the case of South Africa. A study has shown that the average number of compostable plastic bags consumed per month was lowered by two thirds in the first three months after a plastic bag levy was implemented. This effect is likely to be more pronounced with an average levy of two cents.

Environmental impacts of reuse vs recycling

Choosing to recycle biodegradable plastic bags over reused bags can have a negative impact on the environment. However, the impact is dependent on the type of material and the end use. If reused, reusable pla shopping bags can have a much smaller impact than paper or plastic bags.

The Environmental Protection Agency (EPA) website provides information on the environmental impacts of plastic bags. The website offers information on the life cycle of plastic bags, including production and recycling. The website also provides data on the number of bags used and recycled in the United States.

The complexities of recycling processes lead to large amounts of single-use plastic being burned. These wastes emit carbon dioxide into the atmosphere. In addition, the energy involved in burning plastic waste is considerable.

The Environmental Protection Agency website provides an overview of plastic bag recycling, including the number of bags recycled in the United States. The EPA also provides information on the life cycle of plastic bags and the sources of the material used to produce them.
