Swedish eco clean cleaning company has developed into a new type of packaging material. With traditional materials, this new material production without consuming too much energy, its main raw material is abundant reserves of natural materials. After several hours of sun, this packaging material will completely disappear. Therefore, this waste material to solve the litter problem worldwide helpful. Now, whether it is dressing, packing materials, or hold things in bottles, seems plastic, garbage dump filled with plastic waste.
The company chemist Oak? Rosen, 80 years from the 20th century began, the dream can be developed into a hybrid material (part natural, part of the synthesis). This material must have the common plastic durable, lightweight and low-cost features. But when he believed that this plan also temporarily impossible. Later, in 1995, Rosen resigned, set up their own eco-cleaning company where he could study full-time dream of packing material. Initially, Rosen consider using starch as the basic raw materials, but starch biodegradable too fast. He also tried talc. Later, Rosen tried one the world's most common minerals??? Calcium carbonate, which is chalk. Proved the application of calcium carbonate has a very bright future.
Ecological clean company's main factory is located in Helsingborg in southern Sweden. Front yard in the factory a monument erected: a giant egg, is the inspiration it gives a Rosen. Composition of eggshell, 95% of calcium carbonate. For eggs, it is excellent packaging material, but too easily broken. However, Lawson found a way to improve the natural formula. The other 5% of the eggshell is an important element of the "glue", you can make chalk powder into the powder and make the shell Buzhi Yu harder. Rosen, from the natural gas used to extract the plastic polyolefin, rather than natural protein as adhesives. Try a different mixing ratio after Rosen stumbled upon the composition of new environmentally friendly material "clean material" the best ratio: 70% calcium carbonate and 30% polyolefin.
"Clean material" and feel that he does look very like traditional plastic, but it is not plastic. Genju Rosen experiment, "clean material" as hard as glass, as soft as rubber; is plastic, cardboard and aluminum packaging feasible, low-cost alternatives. For environmentalists, this material has many advantages. Although "clean material" containing plastic components, the production cost of energy, but polyolefin impact on the environment is very small, it can be degraded into carbon and oxygen. In addition, use less plastic means less oil. Oil is the basic component of plastic, are non-renewable resources. "Clean material" chalk the main raw material is abundant in many places and cheap, and many of the embedded in the surface or near surface areas. And synthetic plastics, and other fibers used in packaging, paper and cardboard compared to the energy consumed by mining chalk much less. Rosen said: "The production of paper, plastic and aluminum need to build chemical plants, chemical plants once built it will cause pollution. 'Clean material' only use of natural resources, is produced by the earth itself."
"Clean material" the most attractive features is that it is easy to deal with garbage. From "clean material" made from bottles, yogurt cups or candy wrappers can all degrade. Leave them in the picnic table, in the sunlight, a month or two would have turned into sand. If they are thrown into the incinerator, and the remaining ashes are rich in carbonates, help reduce soil acidity. In addition, this material is no "memory". The use of "clean material" made from bottles Caibian, it will remain flattened state, not restitution, in a landfill for only a small space.
