One of the worst forms of plastic pollution may have met its match in the saliva of a humble worm.

Spanish researchers say they've discovered chemicals in the wax worm's drool that break down polyethylene, a tough and durable material.

The researchers say that one hour's exposure to the saliva degrades the plastic as much as years of weathering.

They hope the breakthrough will lead to new natural approaches to deal with plastic pollution.

They've discovered two enzymes in the liquid that can degrade polyethylene at room temperatures and believe it's the first time that such an effective agent has been found in nature.

Polyethylene waste could be a thing of the past

An international team of experts undertaking fundamental research has developed a way of using polyethylene waste (PE) as a feedstock and converted it into valuable chemicals, via light-driven photocatalysis. The University of Adelaide's Professor Shizhang Qiao, Chair of Nanotechnology, and Director, Center for Materials in Energy and Catalysis, at the School of Chemical Engineering, led the team that published their findings in the journal Science Advances. "We have upcycled polyethylene plastic waste into ethylene and propionic acid with high selectivity using atomically dispersed metal catalysts," said Professor Qiao. "An oxidation-coupled room-temperature photocatalysis method was used to convert the waste into valuable products with high selectivity. Nearly 99% of the liquid product is propionic acid, alleviating the problems associated with complex products that then require separation. Renewable solar energy was used rather than industrial processes that consume fossil fuel and emit greenhouse gases."

Wax worm saliva contains enzymes capable of breaking down plastics

A team of CSIC researchers has discovered that wax worm saliva degrades plastic; a discovery with numerous applications for treating or recycling plastic waste. Back in 2017, the team discovered that this worm species (the lepidopteran Galleria mellonella) is able to break down plastic (polyethylene), and now they have discovered just how it does this: its saliva contains enzymes (pertaining to the phenol oxidase family) that can rapidly set off polyethylene degradation at room temperature. These enzymes are the first and only known enzymes capable of degrading polyethylene plastic without requiring pre-treatment, according to Federica Bertocchini, a CSIC researcher at the CIB-CSIC (Centre for Biological Research) who led the study. The results of the work, pending review, have been published in preprint in the BioRxiv online archive.

"For plastic to degrade, oxygen must penetrate the polymer (the plastic molecule). This is the first step in oxidation, which is usually a result of exposure to sunlight or high temperatures, and represents a bottleneck that slows down the degradation of plastics like polyethylene, one of the most resistant polymers," explains Bertocchini. "That is why, under normal environmental conditions, plastic takes months or even years to degrade," she adds.

"Now we have found out that enzymes in the wax worm's saliva perform this crucial step: they oxidize the plastic. This means they can overcome the bottleneck in the plastic degradation process and accelerate its decomposition," she adds.

Thick growth in thin packaging: Ceresana Report on the World Market for Bioplastic Films

Wafer-thin films, often less than 1 millimeter thick, are one of the first areas of application in which bioplastics are able to establish themselves. Although casings made from petroleum products are still usually sold cheaper and in larger quantities, biobased materials such as starch or polylactic acid do not only offer a better public image regarding environmental awareness, but often also tangible advantages: Food packaging made from biodegradable plastics does not have to be disposed of at high cost, but can be composted; organic mulch films can simply be left on the field and plowed under. Ceresana has studied the global market for films made from bioplastics: The new market report forecasts that revenues will increase to around USD 14.2 billion by 2032.

Ultra-High Molecular Weight Polyethylene: Major Things to Understand

Ultra-high molecular weight polyethylene (UHMWPE) is a distinctive thermoplastic polymer with remarkable mechanical and physical qualities. It is polyethylene with the same molecular as regular polyethylene. However, it has a higher molecular weight than polyethylene, which is commonly used. In this blog, let’s understand the major things.

People are living longer lives, particularly in emerging countries such as China and Japan, which are increasing requirements for medical services and UHMW implants. As a result of its advantageous characteristics and tensile strength. Many industries use it significantly, including electronics, automotive, industrial, and heavy equipment. As a result, these factors are anticipated to boost the market. In addition, according to a research report by Astute Analytica, the Global Ultra-High Molecular Weight Polyethylene Market is likely to rise at a compound annual growth rate (CAGR) of 14.7% over the forecast period from 2023 to 2031.

How are UHMWPE products made?

Polymerization:

The polymerization process is carried out at lower temperatures (66-90 °C) and pressures (0.4-0.6 MPa) utilizing a Ziegler-Natta catalyst, namely tri ethyl-aluminum (Al(C2H5)3) and titanium chloride (TiCl4). Polymerization occurs in a solvent, which is a mixed system containing ethylene gas, hexane solvent, and a catalyst. This system is utilized for heat and mass transmission.

Converting of UHMWPE powder to solidified form

UHMWPE is manufactured in powder form and needs to be consolidated at higher pressures and temperatures due to its high melt viscosity. It cannot move like lesser molecular weight polyethylene when heated above its melting temperature. As a result, several thermoplastic manufacturing methods, such as injection molding, blow molding, or screw extrusion are impractical for UHMWPE. Semi-finished UHMWPE is typically manufactured using a ram extruder and compression molding.

Processing:

Unlike LDPE and HDPE, UHMWPE has a high particle size that makes processing challenging. This is due to the large molecular mass and low rheological qualities (low flowability). As a result, polymers such as UHMWPE require high pressure and temperature to achieve proper plasticization.

UHMWPE is processed using one of two ways

Compression molding

Compression molding is a method of molding material into a constrained shape by the use of pressure and heat. Two phases follow this molding procedure. The first is preheating, while the second is pressurizing.

Ram extrusion

The ram extrusion procedure is used to make UHMW rods and tubing profiles. Gravity feeds UHMWPE powder into a chamber, and a hydraulic ram drives the powder from the chamber into the die. The die is the intended plastic shape, such as a specific diameter rod, profile shape, or exterior diameter tube, or inner diameter tube.

The Benefits of UHMWPE

UHMW Polyethylene polymer molecules have both crystalline and amorphous sections. This is known as the “Lamella” structure. The polyethylene chemical chain has a proclivity to rotate around the C-C bonds, resulting in chain folds. Folded of this cord, in turn, allows the molecule to create regionally organized, sheet-like regions called ‘Crystalline lamellae’. The crystallized lamellae are very small. As a result, it cannot be seen with the naked eye (since it is invisible).
