Non-biodegradable plastics are materials that cannot be broken down by natural organisms, acting as a source of pollution. They include commonly used plastics such as polyethylene (PE), nylon (NY), polypropylene (PP), polystyrene (PS), and poly(ethylene terephthalate) (PET). These plastics are designed to be long-lasting, temperature-resistant, and durable, but their resistance to decomposition contributes to environmental concerns. While some plastics can be broken down by microorganisms under specific conditions, these conditions are rare and challenging to recreate in landfills. The widespread use of non-biodegradable plastic bags and bottles has led to pollution, harm to wildlife and humans, and the release of toxic chemicals during incineration or burning.

What You'll Learn
Petroleum-derived plastics
Plastic is a non-biodegradable material, and its increasing accumulation in the environment poses a significant threat to the planet. Petroleum-derived plastics, in particular, have been produced and used extensively due to their attractive properties, such as lightweight, low cost, ease of processing, high strength, and stiffness. These synthetic polymers, derived from petroleum hydrocarbons, include polyethylene (PE), polypropylene (PP), nylon, polyester (PS), polytetrafluoroethylene (PTFE), and epoxy. They are highly versatile and can be found in a wide range of applications, from packaging materials to electronic devices.
The versatility and desirable properties of petroleum-derived plastics have led to their widespread use in various industries. For example, polystyrene is commonly used in disposable spoons, plates, cups, and packaging materials. It can also be recycled and used as a filler for other plastics. Polypropylene, another commonly used petroleum-based polymer, exhibits high strength and flexibility, making it suitable for applications such as bicycle tires, racing sails, and body armor.
However, the non-biodegradable nature of these plastics contributes to environmental pollution. Conventional non-biodegradable polymers resist aging and biological degradation, resulting in pollution after disposal. The accumulation of plastic waste in landfills leads to the release of toxic chemicals into the soil, air, and waterways. Additionally, the incineration of plastics emits pollutants into the air, causing harm to the health of communities.
The development of biodegradable alternatives, such as bioplastics, is crucial to address the environmental impact of petroleum-derived plastics. Bioplastics can be produced from renewable resources like starch, sugar cane, corn starch, or synthetic resins. They offer advantages such as increased soil fertility, reduced accumulation of bulky plastic materials, and lower waste management costs. While bioplastics may not be a perfect solution due to their potential impact on hormone metabolism and the environment, they hold promise in reducing our reliance on petroleum-based polymers.
It is worth noting that some petroleum-derived plastics can undergo biological degradation processes. For example, certain aliphatic polyesters like PCL and PBS can be degraded with enzymes and microorganisms. Additionally, polycarbonates, particularly the aliphatic types, possess some degree of biodegradability. However, the overall indestructibility of petroleum-based polymers remains a significant environmental concern, and the transition to biodegradable alternatives is essential for mitigating the negative consequences of plastic pollution.

Polypropylene
The process of making bioplastics can be expensive due to the cost of the ingredients and the equipment required. However, as more people adopt these biodegradable alternatives, the price is expected to decrease. While polypropylene is not biodegradable, it can be recycled. EnvyPak's polypropylene products, for example, are made from 100% recyclable polypropylene, and they remain recyclable even when treated with the BioPure additive for biodegradability.
The distinction between "biodegradable" and "compostable" is important. All compostable plastics are biodegradable, but not all biodegradable plastics are compostable. Compostable plastics require specific conditions, such as higher temperatures, pressure, and nutrient concentrations, found only in industrial composting plants. Biodegradable plastics, on the other hand, can be decomposed by living organisms, usually microbes, into water, carbon dioxide, and biomass.
While polypropylene is not biodegradable, it has a lower fossil fuel energy cost than some biodegradable plastics like polylactide (PLA). PLA is compostable but is considered non-biodegradable according to American and European standards because it requires artificial composting conditions.

Polystyrene
Despite its widespread use, polystyrene is not biodegradable. It is considered a form of litter that accumulates in the environment, particularly along shores, waterways, and in the Pacific Ocean. Polystyrene can break down into microplastics, which are harmful to animals and the environment. The manufacturing process of polystyrene also releases chemical byproducts that contaminate the air and water.
Recycling polystyrene is challenging due to its low melting point and other physical properties. It is not commonly recycled, and only specific types of polystyrene foam are accepted by recycling facilities.
There are alternative materials to polystyrene, such as bamboo, which is compostable, biodegradable, and eco-friendly. Mineral-filled polypropylene containers are another alternative, although they are still mostly made of plastic and may not be accepted by recycling centers.

Polyethylene
PE is an inert and highly recalcitrant material, and further studies on its degradation and biodegradability are needed. Current problems with PE include its waste management and recycling. For example, it has been challenging to biodegrade more than 50% of PE into biomass, CO2, water, and minerals through biological processes.
Some approaches to reduce the accumulation and contamination derived from PE include the 3R methodology, recycling, chemical and structure modification, and the synthesis and use of bio-based PE. For instance, Singh et al. evaluated the biodegradable behaviour of commercial PE films in a natural composting environment over six months.
Oxo-biodegradable polyethylene has been shown to degrade in a soil environment. For instance, oxo-biodegradation of low-density polyethylene containing a proprietary manganese-salt-based additive showed 91% biodegradation in a soil environment after 24 months. Additionally, Niall Dunne from Polymateria created polyethylene film which degraded within 226 days.

Plastic waste management
To effectively manage plastic waste, several strategies must be implemented. Firstly, there is a need to reduce plastic consumption and promote sustainable alternatives. This involves encouraging the use of biodegradable plastics, which can be bio-based or fossil-based, and have similar properties to traditional plastics while minimizing environmental impact. However, the challenge lies in ensuring proper degradation conditions for biodegradable plastics, as they may not degrade as efficiently in real-world settings.
Secondly, recycling and waste management infrastructure must be improved. While recycling can divert waste from landfills, the current recycling rate of plastics is low, and recycling only delays final disposal. Therefore, a systematic approach to waste management is necessary, including proper collection, handling, and sorting of plastic waste. Contamination, caused by inaccurate labeling and a lack of understanding of waste management practices, is a significant issue that requires consumer and corporate education. Implementing universal labeling and clear disposal instructions can help address contamination.
Additionally, governments and regulatory bodies play a crucial role in enacting stringent waste management policies. This includes banning non-degradable and non-recyclable plastics, encouraging the use of bio-based materials, and promoting sustainable practices throughout the product lifecycle, from design to end-of-life management. Advancements in technology and innovation are key to developing sustainable alternatives, improving recycling technologies, and exploring waste-to-energy initiatives.
Lastly, raising awareness among consumers about the environmental impact of non-biodegradable plastics is essential. Educating individuals about responsible waste management practices and sustainable consumption habits can foster a sense of responsibility and contribute to a cleaner, healthier future. By addressing plastic waste management through these strategies, we can minimize the harmful impacts of non-biodegradable plastics on our environment and ecosystems.
