Plastic Bacteria, an Ecological Solution

What are Plastic Bacteria?

Bioplastics – or bacterial plastics – are biosourced polymers produced by microorganisms from renewable resources. Under nutrient stress, these microbes produce the famous material naturally. The materials (e.g. PHA) are biodegradable and compostable, degrading naturally in the environment without toxic residue.

The Benefits of Plastic Bacteria

• Biodegradability: bioplastics break down naturally in the environment, reducing plastic pollution.
• Compostability: they can be composted, contributing to the production of high-quality compost.
• Reduced carbon footprint: the production of bioplastics emits fewer greenhouse gases than traditional plastics.
• Reduced dependence on fossil fuels: bioplastics are made from renewable resources, reducing dependence on fossil fuels.

Types of Plastic Bacteria

There are several types of bioplastics, each with specific properties and applications:

• PHA (Polyhydroxyalkanoates): PHAs are biodegradable polymers and plastics formulated by bacteria. They are used in a wide variety of applications, from packaging (particularly films) to consumer goods and the medical sector.
• PLA (Polylactic Acid): PLA is a bioplastic obtained from maize or sugar cane starch. Applications: food packaging, textiles, medical products, etc.
• PBAT (Polybutylene adipate-co-terephthalate): PBAT is a biodegradable bioplastic used to make compostable bags or agricultural film.

Plastic Bacteria: Industrial Applications

Ecological Food Packaging

Often used for food packaging, the main advantage of bioplastics is that they are biodegradable or compostable, making them less polluting than conventional plastics. Around 65% of outlets for bioplastics are food packaging, which simplifies the management of organic waste, as users no longer need to separate food waste from packaging.

Medical Products in Bioplastics

Bioplastics are commonly used in the manufacture of medical devices such as sutures, implants, prostheses, dressings and drug capsules. Their biocompatibility and biodegradability are important advantages in these medical applications, as they guarantee their safety in the body and reduce the need to remove devices after use.

Consumer Goods in PHA

Bioplastics are used to produce a wide variety of consumer goods, from toys and clothing to high-tech products. Preferred by consumers because they are biodegradable, PHA products have a limited impact on the environment. Also legitimised by the reduction in CO2 emissions and improved energy efficiency, bioplastics are proving to be competitive when it comes to creating new economical products.

The Challenges and Prospects for Plastic Bacteria

Although plastics of bacterial origin have different qualities, they have to overcome a number of obstacles:

• Production costs: the production prices of bioplastics are currently higher than those of petroleum-based plastics.
• Recycling infrastructure: recycling infrastructure adapted to bioplastics is not yet available.
• Consumer awareness: customers need to be made aware of the benefits of bioplastics in order to adopt these new materials.

Naturally, there are a number of favourable prospects for bacterially produced plastics. As demand for sustainable solutions grows, so does investment in bioplastics research and development. The global bioplastics market has been estimated at USD 13.04 billion in 2022 and is expected to reach USD 45.72 billion by 2030, with growth of 17.43% between 2023 and 2030. Finally, technological solutions and favourable public policies should also contribute to the development of bioplastics.
