Bubbles are a very versatile material that we see in our packaging, whether we buy furniture, accessories, or electrical appliances. Foam plays a role in insulation, sound insulation and light weight in high-rise buildings, aviation, and automobiles. Among many synthetic materials, foam is also a "core" material, which increases strength, reduces weight, and reduces energy loss and insulation. The commonly used foams today are based on polymers, which have a great impact on the environment. On the one hand, these materials are not easily recyclable; on the other hand, these materials are made from petroleum-refined products, so scientists are trying to find environmentally friendly raw materials to make foam.
Recently, a doctor at the Hebrew University of Jerusalem in Jerusalem invented the method of foaming nanocrystalline cellulose (NCC). At the same time, he also found out how to make nanocrystalline cellulose using waste from paper mills.
In the papermaking process, a large amount of fiber is treated as waste. In Europe, for example, paper mills discharge 11 million tons of fiber waste each year.
The PhD found that these fiber scraps are an excellent raw material for the manufacture of nanocrystalline cellulose, because the size of the fiber waste discharged from these paper mills is very small and only a relatively small number of processes are required to process these fiber wastes into nanocrystalline cellulose. .
The nanocrystalline cellulose foam he invented is porous, lightweight, and has high strength. The technical specifications of the nanocrystalline cellulose foam are comparable to those of foam produced by technology at this stage. Experts anticipate that the successful use of technology for the effective use of industrial waste in foam manufacturing will greatly reduce its dependence on oil.
