Does rubber pollute?
Synthetic and natural rubber dust and fragments now occur in food, airborne as particulates in air pollution, hidden in the earth as soil pollution, and in waterways, lakes and the sea.
Why is rubber eco-friendly?
Rubber can and should be produced without clearing natural forests. When done responsibly, rubber production increases biodiversity and carbon sequestration, and reduces carbon dioxide emissions from deforestation. It also avoids human and labor rights violations, as well as land grabs.
Why is rubber not recycled?
Although tires are almost half rubber, the rubber can't simply be melted down and reused as many polymers can be. That's because the rubber is vulcanized—cross-linked with sulfur in a process invented by Charles Goodyear in 1839. Vulcanization imparts needed mechanical properties but is not easily reversed.
Does rubber pollute water?

What are the environmental issues of natural rubber?
Natural rubber processing sector consumes large volumes of water and energy and uses large amount of chemicals as well as other utilities. It also discharges massive amounts of wastes and effluents. The most common environmental issues are wastewater containing chemicals and smell, hazardous waste, noise, and thermal emission. In order to reduce the damage in the environment, waste abatement and management in natural rubber processing sector should be handled properly.
What is rubber made of?
First, there is natural rubber, made from the oozy latex material that is extracted from the tree Hevea brasiliensis, sometimes called the Para rubber tree, and can be found on plantations across the world. Next, there is recycled rubber, rubber that is taken from recycled tires, ground up and turned into crumb, and reformed based on the demands of the market. In playgrounds it could be flooring or in commercial applications recycled rubber sheets could be used to produce specialized parts. Last, there is reclaimed rubber, which is discarded elastomer having undergone the process of de-vulcanization. This allows their use in production similar to other virgin materials. All of these are compared with petroleum-based elastomers which are so-called less eco-friendly rubber products. Each of these is a form of environmentally friendly rubber, and each is demanded in the open market!
How long does silicone rubber last?
On your garage work table and out of the sun, silicone rubber might last a good fifty years at normal temps. In the sun, maybe ten. As it ages, it shrinks a little. It becomes too cracked and stiff to be useful as a [flexible] rubber thing. But still functions as a door stop. It still has much of its compression strength. So even then it will still have some use. The oxidation is affecting the outside of the bulk much more than the inside. It depends on how far gone you want it to be, to say it’s done. So, first you define what its dimensions are. And temp and humidity climate cycles. So even then you will have a hard time saying how long it will last, without describing the article and its exposure, and how you define its end of life. [Range of failures: “No longer flexible” or “holds dimension” happens in decades. “Turns to dust” might take tens of decades]. Those sealant tubes of silicone caulk that claim to be good for 50 years. They might be good for 50 years under compressive loads. But not compliance, where seals tend to fail in a combination of flexure and tensile stress. [Shear]. Once they lose maybe half their flexibility, their ability to handle seal flexures is in serious doubt.

Does silicone oil oxidize?
Cheaper and more flexible silicones have silicone oil in them as filler. The cheapest versions likely have a little mineral oil. These contribute to shrinkage and faster deterioration as the unbound oil in the matrix, tends to slowly migrate to the surface and oxidize [to CO2]. Heat and flexure, and solvent exposure increases the migration rate. And most [non-mineral] fillers, like the oils and plasticizers, oxidize faster than silicone, and become typical oxidized hydrocarbon byproducts [again, eventually to CO2].

Is rubber sustainable?
So, is rubber eco friendly? Recycled rubber, reclaimed rubber, and products made from the Para tree sap are all sustainable materials. When rubber is discarded and left on its own, or when it is created in archaic factories, using crude techniques, and the products and bi-products are not managed carefully and consciously, then and only then can rubber become harmful to the environment. Unassuming environmentally friendly rubber products like recycled rubber sheets are now available at far lower costs than petroleum-based elastomers and are used in thousands of applications as effective substitutes. Thankfully, for the most part, rubber is created and produced with the intent of preserving our environment, not harming it!
What is rubber made of?
Natural Rubber which is made from a runny, milky white liquid called latex that is found in certain plants, when you cut into them. Over 200 plants in the world can produce this latex, but the most productive plants are the Pará rubber trees (Hevea brasiliensis), a member of the spurge family, Euphorbiaceae.
What temperature is natural rubber heated to?
Natural rubber is often vulcanized, which means it is heated to about 140°C (280°F) and sulphur, peroxide or bisphenol are then added to enhance its resistance and elasticity, and to stabilise the final material or product. We can thank Charles Goodyear who in 1839 developed this method to strengthened the rubber for vehicle tyres.
How is rubber harvested?
Currently, natural rubber is harvested mainly in the form of the latex (the sticky, milky colloid liquid) by tapping into the tree and bringing the latex, often coagulated to a plant for processing. The latex is then strained, diluted with water, treated with acid, before rolling into sheets, drying and then shipped to make the various products. ...
