China creates a new, eco-friendly plastic out of SALMON SPERM. The oil is combined with vegetable oils to form a soft and recyclable gel. This can then be used in electronics. But it needs to be dried.

  • The salmon sperm is combined with vegetable oil to form a hydrogel
  • To remove excess water from the hydrogel, it is frozen to set it solid. 
  • Scientists have been able to create objects such as cups and bowls out of substance
  • You can recycle the plastic by placing it under water – this turns it back into a gel that can then be used to make another product. 

A new type of eco-friendly plastic is made with an unlikely ingredient – salmon sperm.

Chinese scientists extracted the DNA of fish from their testes, and then combined it with vegetable oils to create a soft, flexible substance called a Hydrogel.

To create plastic items, the substance can be molded using molds.

You can recycle natural plastic by placing it underwater. This will convert it to hydrogel, allowing you to make new items.

A team of Chinese scientists extracted DNA from the fish's testes and combined it with vegetable oil to create a squishy, malleable substance known as a hydrogel. The substance is then be formed into different shapes using molds to create items typically made from plastic

Chinese scientists created a hydrogel from DNA extracted from the test fishes. The mixture of vegetable oil and DNA was able to produce a soft and malleable substance called hydrogel. To create plastic items, the substance is then molded with molds.

There are more than 380,000,000 tons of plastic in the world each year. Each day around 8 million pieces of plastic end up in the ocean, where they pollute water, wildlife, and our drinking water.

The study, published in the Journal of the American Chemical Society says that plastics have important functions in modern society.

“To alleviate this problem, we can develop sustainable bioplastics that will be compatible with the entire material lifecycle.”

“We report on a sustainable bioplastic made out of natural DNA and biomass-derived isomers. It’s called DNA plastics.”

The process starts with short strands of DNA from the salmon's sperm, which is then mixed with a chemical found in vegetable oil. The gel is freeze dried to remove, which allowed the gel to solidify. The team was then able test their innovation by making certain items

Start with DNA from the salmon’s eggs. Next, a vegetable oil chemical is added to it. It is then removed by freezing, which allows the gel to set. The gel was removed from the freezer and allowed to solidify.

The Times says that the process begins with DNA strands from salmon’s eggs. These are then combined with vegetable oil chemical.

The gel is freeze dried to remove, which allowed the gel  to solidify.

The group was then able to test its innovation by creating certain products.

The entire process, from start to finish, produces less than five percent of the carbon emissions released in the production of traditional plastic – and the innovation is completely recyclable.

The world produces more than 380 million tons of plastic each year and everyday, around eight million pieces of plastic make their way into the ocean where they pollute waters, animals and even our own drinking water

There are more than 380 million tonnes of plastic in the world each year. Around eight million pieces of plastic end up in the ocean every day. They pollute waterways, wildlife, and our drinking water.

The study states that sustainability includes all aspects of production, use and disposal of DNA plastics.

You can also use DNA plastics to make arbitrary-designed products, such as plastic cups.

“This research provides a way to convert biobased hydrogel into bioplastic. It also demonstrates closed-loop recycling DNA plastics. This will help to develop sustainable materials.


Scientists studying river pollution have found that urban flooding has caused microplastics in our oceans to move faster than we thought.

Greater Manchester’s waterways are so contaminated with microplastics, that they are present in all samples.

As part of the largest catchment-wide investigation anywhere on the planet, scientists discovered this polluting factor is an important contributor to pollution in the oceans.

The ecosystems are impacted by this debris, which includes microbeads as well as microfibres.

These small, toxic particles were found in 40 waterways around Manchester by scientists who tested them all.

Microplastics include microbeads (microfibres), microplastics and small plastic pieces.

They have been well-known for entering river systems via multiple sources, including storm water drains and industrial effluent.

However, it is believed that around 90% of the microplastic pollution in the oceans comes from land. Not much information is available about how they move.

According to University of Manchester researchers, most rivers had approximately 517,000 particles per square metre.

After a time of severe flooding, researchers did resampling at each site.

They discovered that contamination levels had dropped at most of them and that flooding had destroyed about 70% of the microplastics on the riverbed.

These floods can result in large amounts of microplastics being transferred from cities to the oceans.
