China develops new solution to remove microplastics from water
The new eco-friendly material is able to attract and interact with different types of microplastics
China has developed a new reusable and biodegradable porous material that can absorb microplastics from water with up to 99.8 per cent efficiency.
The researchers used an eco-friendly fibre foam material made from chitin derived from squid bone and cellulose from cotton.
The porous structure of this material allows it to attract and interact with various types of microplastics often found in electronics, food packaging, textiles and other industrial goods. This is reported by China Daily, a partner of TV BRICS.
The team tested the effectiveness of the material on samples from four real water sources: irrigation, lake, sea and pond to find out how it performs under natural conditions.
In the experiments, the foamed material absorbed almost 100 per cent of the microplastics in the first cycles, and removal levels of this biopolymer material exceeded 95 per cent after five cycles, highlighting its good reusability.
According to the study, the material's adsorption capacity is virtually unaffected by inorganic particles, heavy metals, organic pollutants and microorganisms in water.
The team has already applied for a patent for this technology, hoping to implement it in a real water purification system or home filters in the near future.

Vladimir PutinPresident of Russia"We are developing mutual trade, which is growing; it increased by over 12 per cent last year. We have a joint commission working in this sphere. Our focus is on agriculture, shipbuilding, information technology and energy, including nuclear power. We have signed a free trade agreement between the Eurasian Economic Union and Indonesia. Jakarta is our reliable and old friend within ASEAN. We are working together at all international platforms, including the UN" -

Joao Paulo CapobiancoBrazilian Minister of the Environment and Climate Change"The BRICS countries have a very high level of responsibility because they share an important part of the world's biodiversity, landscapes, populations, food production and water resources. So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification"
