A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers from, among others, NIOZ published their results in the scientific journal Science of the Total Environment. They expect that many more plastic degrading fungi are living in deeper parts of the ocean. The fungus Parengyodontium album lives together with other marine microbes in thin layers on plastic litter in the ocean. Marine microbiologists from the Royal Netherlands Institute for Sea Research (NIOZ) discovered that the fungus is capable of breaking down particles of the plastic polyethylene (PE), the most abundant of all plastics that have ended up in the ocean. The NIOZ researchers cooperated with colleagues from Utrecht University, the Ocean Cleanup Foundation and research institutes in Paris, Copenhagen and St Gallen, Switzerland. The finding allows the fungus to join a very short list of plastic-degrading marine fungi: only four species have been found to date. A larger number of bacteria was already known to be able to degrade plastic.

Polyethylene Recycling

Polyethylene - either in the form of high density polyethylene (HDPE), low density polyethylene (LDPE), or another - is considered to be the mostly widely used plastic in the world. It is used to make plastic bags, food containers, cutting boards, etc. However, rates of plastic recycling as a whole are considered relatively low compared to other materials like paper or some metals and polyethylene is no exception to this. This is partially because most plastics, polyethylene included, cannot be infinitely recycled in the way of most metals. Recycling of polyethylene typically results in a decrease in strength of the resulting product, especially after repeated recycling.

Polyolefin Resins: A Look at Their Wide Range of Uses

Polyolefins are a class of polymers formed from the polymerization of olefins such as ethylene and propylene. These polymers include polyethylene, polypropylene, and other polymers made from alkenes. Polyolefins exhibit many useful properties that have enabled their widespread use in a variety of industries and applications.

Chemical Structure and Properties

Polyolefins are hydrocarbon polymers, meaning they are composed purely of hydrogen and carbon atoms in long molecular chains. The main difference between polyolefin types is the structure of these repeating molecular units - polyethylene contains an ethane repeating unit (–CH2–CH2–) while polypropylene contains a propene repeating unit (–CH2–CH(CH3)–).

The carbon backbone structure gives Polyolefin Resins their main mechanical properties. The strong covalent carbon-carbon bonds make polyolefins rigid yet flexible and resistant to chemicals and corrosion. The lack of polar chemical groups also means polyolefins are generally non-polar and hydrophobic – this property enables uses where water or moisture resistance is important. Polyolefins also have low densities, ranging from 0.89–0.97 g/cm3 for LDPE and 0.90–0.92 g/cm3 for polypropylene.

Polyethylene

Polyethylene (PE) is produced in various forms depending on process variables used during Polyolefin Resins. Low-density polyethylene (LDPE) resin is lightly branched with densities around 0.915-0.940 g/cm3. LDPE products have good clarity and flexibility ideal for food packaging films, shrink wrap, and trash bags.

Linear low-density polyethylene (LLDPE) has a linear polymer chain structure with short branches, lowering densities to 0.910-0.940 g/cm3. LLDPE resins can be processed at higher rates than LDPE and offer good impact resistance suitable for industrial films and lamination applications.

High-density polyethylene (HDPE) has fewer and shorter branches, making it essentially linear. HDPE has densities in the range of 0.941-0.970 g/cm3, imparting high strength and stiffness properties useful for pipes, bottles, containers, and durable household goods.

Polypropylene

Polypropylene (PP) differs from PE in having a pendant methyl group on every third carbon in its polymer chain. Isotactic polypropylene, the most common type, has these methyl groups oriented on the same side of the polymer backbone. This gives isotactic PP higher melting points than LDPE or HDPE, ranging from 160-171°C depending on composition.

Isotactic PP has a balance of properties making it suitable for a huge diversity of applications. It is rigid yet tough, with high heat distortion temperatures up to 120°C. Common uses include caps and closures, textiles, rope and cord, automotive components, pipes, living hinges, and medical devices and components. Atactic or syndiotactic PP varieties offer varying property profiles.

Uses and Applications

As the most widely produced plastics globally, Polyolefin Resins are highly versatile materials that bring value to many markets:

Packaging - PE and PP resins dominate the packaging industry with their moisture and chemical resistance. They are used extensively for food packaging, shrink and stretch films, bags, bottles, containers and more.

Consumer and Industrial Products - Durables like tools, pails, detergent bottles, cable jacketing, automotive components, car interiors and more capitalize on polyolefin toughness, durability and design freedom. Outdoor furniture, pipe systems, and construction products also use polyolefins extensively.

Medical Devices - The biocompatibility and processing characteristics of medical grade polyolefins support use in devices, components, tubing, gowns, drapes and other single-use applications.

Textiles - Spunbond PE and PP nonwovens are major materials for geotextiles, diapers, wipes and hygiene products, filtration media, and other textile applications. Fiber and filament grades also see use in carpet and apparel fibers.

Polyolefin Resins are amongst humanity's most significant material inventions. The unmatched versatility and balanced mechanical properties of PE and PP, coupled with facile production methods, have enabled polyolefins to permeate nearly every industry and market segment. With global annual production now exceeding 100 million tons, polyolefins will assuredly continue to play an outsized role supporting modern society and economies into the foreseeable future.
