As early as in 1991, Katrina Cornish of the US Department of Agriculture's Agricultural Research Institute pointed out that in the next ten years, genetic engineering methods will be used to produce high-quality natural rubber from Myrodanthus weeds and yeasts, reducing the United States' import of synthetic rubber and petroleum as raw materials. rely. Researchers have been searching for shortcuts to discover genes that can use high-yield rubber from the genus Polygonum or other fast-growing plants, or proliferative yeasts and bacteria. Today, "weeds" are expected to move out of the laboratory and become a reality.
A few days ago, researchers from Ford Motor Company and Ohio State University are working on the research of weeds and rubber, and have achieved initial success. When the spring of each year approaches, and large patches of dandelion begin to grow and extract buds, the weeds that need to be eradicated may be a new source of sustainable raw materials that can be used to replace rubber.
Ford R&D engineer Angela Harris said: “We are always looking for new sustainable materials for vehicles with smaller carbon footprints, and it is better to be able to grow them locally. Synthetic rubber is not a sustainable material, so we want to We use less on our vehicles. Dandelion has great potential for use on our vehicles and may become a natural alternative to synthetic rubber."
However, not all dandelions can be used as a sustainable alternative to rubber. The dandelion suitable for this project is a scientific name called "rubber grass" Russian dandelion. Ohio State University's Agricultural Research and Development Center (OARDC) is nurturing this plant. The milky substance that oozes out from the root of this dandelion can be used to make rubber.
According to Bill Ravlin, deputy director of OARDC, "How to eliminate weeds, this issue is critical to the development of TKS as a source of raw materials for commercial natural rubber in the United States. In the future, Ford may use this material as a plasticizer. Helps to improve the impact resistance of plastics. This improved material can be used to make cup holders, floor mats, upholstery bars, etc."
Harris said: "It's strange that weeds are grown neatly in the greenhouse, but these dandelions are likely to become sustainable raw materials for our cars in the future." Ford's researchers were used to make dandelion rubber before it was put into practical use. The original qualities of this material will be tested to evaluate how they will perform in the various plastic parts of the car and ensure that they meet the durability criteria. In addition to dandelion, the team is also investigating the possibility of the use of natural gum as a raw material for Gumkin (a common shrub in the Southwestern United States). OARDC is also growing this plant and it can also be grown in the home.
It is understood that Ford Motor Co., Ltd. has promised to “reduce, recycle, reuse†as part of the company’s global sustainability strategy. This strategy aims to reduce the environmental footprint and accelerate the development of advanced fuel-efficient vehicle technologies worldwide. Development. In the past few years, as long as it is more environmentally friendly non-metallic renewable bio-based materials in specific applications, Ford Motors has concentrated its efforts on increasing the use of these materials as much as possible. Specific example results include: Soybeans as raw materials Foam chair cushions, straw-filled plastics, underbody systems made from recycled resins, seat covers made from recycled yarn, and interior parts made of natural fiber plastics.
We are very professional PE Tarpaulin manufacture since 1998. We can produce all the colors in tarpaulin line, such as blue, green, olive green, black, brown, orange, silver, camouflage, red, yellow, white, etc. Black PE Tarpaulin is one best selling item. As to the plastic tarpaulin have the features of tear-proof, water-proof, washable, anti-rot and UV-stabilized, so most of tarp sheet are used for covering, such as storage cover, utility cover, construction cover, outdoor and home covers, refugee tent, agricultural cover, temporary warehouse, canopy, irrigation dams, scaffolding covers, etc. Some customers even make one side black color, the other side different color for special usage, such as swimming pool.
Both of ready made sheet and in roll black PE tarp can be produced. Ready made sheet means the tarp sheet with reinforced pp rope inside four edges and aluminium eyelet every 3 feet or every 1 meter. In Roll Tarp means the Tarpaulin Fabric roll in the paper core directly
