INDUSTRIES WE SERVE

We offer sustainable waste solutions for industries that deal with waste streams from their production processes. From carbon black to rubber PCU, and steel cord to rubber compounds, we can process different grades into a consistent source of sustainable materials suitable for a wide range of uses.

Elastomers & Rubber Polymers

Rubber Polymers

Rubber polymers are available in mainly two distinct types. First, the natural rubber is derived from the milky sap or latex which is harvested from the rubber tree. The other type is synthetic rubber, created through a chemical synthesis process in industrial facilities using oil-based feedstocks. There are lots of reasons a rubber polymer material cannot be used in the intended way. Natural rubbers can be contaminated and over-aged or their quality can become deteriorated due to environmental circumstances. For synthetic rubber, issues in production, lack of processing control, and contamination will create rubber materials that need to be wasted but can be re-used in specific applications.

Thermoplastic elastomers

Thermoplastic elastomers (TPE) combine the characteristics of both thermoplastic and elastomers and are used in application areas where rubber materials are used, like footwear and consumer goods. TPEs that cannot be used anymore for intended use due to off-spec, contamination or other reasons can still be re-purposed for use in specific selected applications.

Rubber PCU (Plant clean-up)

Rubber PCU is a rubber waste product generated during routine cleaning and maintenance activities of a synthetic rubber plant. Due to its nature, rubber PCU has a broad range of properties, and high moisture content and is available in different shapes (bales, flocks, crumb, lumps). The material will need to be reworked, cleaned, and mixed with other rubber sources before it can be re-used.

Carbon Black

Carbon black

Made from partially burned hydrocarbons, carbon black is a fine powder with a wide variety of applications. During the production process of carbon black there are a lot of instances when the produced material cannot be used for its intended purpose, e.g., carbon black can be off-spec or contaminated, can contain too high levels of moisture or is simply over-aged. In the rubber process industry, waste carbon black is also generated through spillage of carbon black (floor sweepings) or carbon black that has been filtered out of the air (filter dust). We can handle it all.

Tire Industry

Green Tires

During the production of a tire, there is a stage when a complete tire has been assembled out of semi-finished products before vulcanization takes place into what is known as a “green tire”. Rejected green tires are, due to their complex build, a waste stream difficult to handle, as the green tires need to be completely disassembled into their primary components. And that’s exactly where we come in.

Steel cord / rubberized wire friction

Rubberized steel cord, also called wire friction in the US, is an essential component in the assembly of a tire. Its main function is to reinforce the tire. It’s made from a special type of steel that has been coated with a layer of unvulcanized rubber. During the assembly process of the tire, significant amounts of steel cord waste are produced. Due to its nature, it’s difficult to separate the various reusable material fractions, but quite possible for us.

Rubber Compounds

Rubber compounds refer to mixtures of various raw materials that are blended to create a specific rubber formulation for a specific application. These compounds consist of rubber polymers, fillers, plasticizers, carbon blacks, curing agents and other additives. Errors in the formulation or the production process will create off-spec compounds that cannot be used for their original application. Furthermore, during the compounding process, change-over and waste is generated. The challenge in the re-use of these materials is the fact that curing agents have been added, significantly limiting the shelf life of these materials. A challenge VESPER loves to tackle.

Textile cord/fabric friction

Textile cord is a type of reinforcement material used for instance in the manufacturing of tires and conveyor belts. It consists of textile fibres, such as polyester or nylon, that are coated or impregnated with rubber. In the manufacturing process, textile cord waste is generated because of defects or waste off-cuts.
