Researchers at the Harvard Institute for Biological Engineering (Wyss) claimed that the new bioplastic products they use to produce shrimp are omnipotent, more easily degradable and can even increase plant growth rates. They have used experiments with California black-eyed pea plants to show that the breakdown of chitosan can really promote plant growth in the same soil.
In the United States alone, 34 million tons of plastic waste is produced each year, but only 7% of the waste is recycled. Plastic products have many advantages: they are sturdy, cheap, and easy to produce, but these characteristics are precisely what they cause to the environment and human beings. Because the chemical structure of plastics is too strong, they can not be degraded in 1000 years, and damage the soil, affect plant growth, and even cause an ecological disaster. If plastics are abandoned in the ocean, they can endanger the life of marine life. About 1 million tons of rubbish is now floating in the ocean currents.
How should we respond? Today's society is so dependent on plastic that all attempts to resist plastic have failed. But what if we choose a safe, more plastic-like alternative? You may have already thought of it, that is, bioplastics, a non-hazardous material made from renewable cellulose. But this alternative is not the best because they are slow and inadequate in the soil. And it uses a very small area and can only be used for packaging materials or simple food or beverage containers.
Researchers at the Harvard Institute for Biological Engineering (Wyss) claimed that the new bioplastic products they use to produce shrimp are omnipotent, more easily degradable and can even increase plant growth rates. This kind of plastic is made of substances made of chitosan, which is a state of existence of crust, the second most widely distributed substance on the earth, and the main component of hard crusts of crustaceans such as insects. Cuticle, butterfly's elastic wings.
This biopharmaceutical called “shrilk†produced with chitosan can be produced in an innovative way at a low cost and easily, and retains the strong mechanical properties of chitosan. This allows engineers to use traditional die-casting or injection molding techniques for the first time to make recyclable materials into complex shaped 3D products.
“The business community desperately needs a sustainable material that can be produced on a large scale,†said Donald, chairman of the Harvard Institute for Biological Engineering (Wyss) in March. “Our scalable production mode shows that this kind of easy access to chitosan Low-cost materials making plastics are feasible and have the potential for large-scale investment in industrial production."
Once thrown into landfills, the “shrilk†material can be broken down in a matter of weeks, no longer a few hundred years of plastic now. Even more exciting is that when shrilk's material is broken down, they will release nutrients to the soil to promote plant growth. They have used experiments with California black-eyed pea plants to show that the breakdown of chitosan can really promote plant growth in the same soil.
