Eco-Friendly Materials for Sustainable Tire Manufacturing

Tire tread rubber composition with high biobased content and reduced carbon footprint. The tread rubber is made by mixing specific amounts of raw rubber, reinforcing filler, activator, plasticizer, anti-aging agent, accelerator, and vulcanizing agent. The composition aims to replace fossil-based rubber with biobased rubber, like itaconate rubber, to reduce dependence on petroleum. The low-temperature vulcanization process and omitting silane coupling agent further reduce carbon emissions. The composition provides tires with high biobased content, good wet grip, and lower rolling resistance.

Bioengineered rubber made from renewable resources with improved properties compared to conventional rubber. The bioengineered rubber is prepared by combining epoxidized natural rubber, bio-based elastic material, wheat straw powder, ethanol, silane coupling agent, and vulcanizing agent. The specific component proportions can vary within certain ranges. The bioengineered rubber has enhanced elasticity, flame retardance, wear resistance, weather resistance, and low temperature flexibility compared to conventional rubber.

Rubber material containing recycled textile fibers that is environmentally friendly and can be used in applications like tires, belts, and shoe soles. The rubber compound is prepared by combining textile fibers, butadiene rubber, isoprene rubber, styrene butadiene rubber, and reinforcing agent. The textile fibers can be recycled materials like scraps from shoe production or old shoes. The rubber compound provides properties like strength and tear resistance. The rubber material can be prepared by compounding the ingredients and processing them into the desired shape.

Rubber composition for tires that meets the requirements of circular economy while also providing good tire performance. The composition includes a rubber derived from biomass through aromatic ethylene compound and diene polymerization. The biomass rubber has a contemporary carbon percentage (pMC) of 1% or more. This biomass originated rubber provides fuel economy, wet grip, and processability benefits while also addressing circular economy concerns. The composition can also contain other biomass derived components like butadiene, styrene, and alcohols. The biomass pathway involves converting renewable resources into tire rubber.

Environmentally friendly winter tire compound using biodegradable filler derived from organic waste. The method involves pyrolyzing organic material at controlled temperatures to convert it into a biodegradable filler. This filler is then mixed with rubber compounds for tire treads to replace conventional fillers like silica. The biodegradable filler improves tire performance while reducing reliance on fossil resources and addressing environmental concerns.

Tire> Below, the tire according to the present invention is demonstrated in detail. The tire according to the present invention is characterized in that the elastomer composition according to the present invention is used as a composition for a tire. Since the elastomer composition according to the present invention is characterized in that the amount of the elastomer component used is reduced, the elastomer composition according to the present invention can be used for the composition for a tire. Since the elastomer composition according to the present invention is characterized in that the amount of the elastomer component used is reduced, the elastomer component used for the composition for a tire is reduced, and the cost can be reduced. In addition, since the elastomer component used for the composition for a tire is reduced, the amount of petroleum resources used can be reduced, and it is possible to reduce environmental load.

Elastomer composition for tires with reduced elastomer content that uses alternative materials derived from fermentation residues and plant extraction residues. The composition contains blended components from fermentation residues like methane, ethanol, hydrogen fermentation, and plant extraction residues like cellulose and hemicellulose fibers. The blend has an elastic modulus ratio in the high strain region to the low strain region of 2.7 or less. This composition reduces the amount of traditional elastomer needed in tires while using inexpensive, low environmental impact materials.

Elastomer composition for tires with reduced petroleum usage by blending a residue from organic matter fermentation with the elastomer. The residue contains less than 6% of components other than the main component. This reduces the amount of elastomer needed. The residue is also processed to remove saccharides, citric acid, and amino acids to less than 6% total. This avoids aggregation and property degradation when blended with the elastomer. The fermentation residue provides a low-cost, low-environmental-impact alternative to traditional elastomers.

A biodegradable rubber composition for tires that improves fuel efficiency and reduces carbon footprint. The composition contains natural rubber and/or diene rubber, along with biodegradable fatty polyester. The biodegradable polyester content is 0.5-80 parts by mass relative to 100 parts of the total rubber. The composition improves rolling resistance and reduces energy consumption in tires compared to conventional rubber compounds. The biodegradable polyester allows partial degradation of the tire during use, which could enable recycling and reuse of tire materials after end-of-life.

Environmentally friendly pneumatic radial tire that aims to reduce CO2 emissions during manufacturing and disposal by replacing fossil-based materials with plant-derived alternatives. The tire uses plant-based rubber compositions with high proportions of plant-derived materials like natural rubber, fatty acids, resins, and vegetable oil carbon black. The goal is to have a whole tire with at least 45% plant-derived raw materials by weight. This reduces the amount of CO2 generated compared to using fossil-based materials.

Eco-tire made with 75% or more of non-petroleum resources to reduce reliance on petroleum-based materials. The tire replaces synthetic rubber, carbon black, petroleum oils, and synthetic fibers with materials derived from plants, minerals, shells, etc. This reduces the amount of petroleum resources used in tire production. The tire also uses a cord made of non-petroleum materials like rayon instead of synthetic fibers. The goal is to make a more environmentally friendly tire by substituting a significant portion of the petroleum-based components with resources from non-fossil sources.

Rubber composition containing enzyme-decomposed rubber obtained by using an oxidase to decompose vulcanized rubber. The decomposed rubber is blended with virgin rubber to create a composition with improved properties like fracture strength and wear resistance compared to recycled rubber alone. The oxidase used is one that can decompose lignin. By decomposing the vulcanized rubber instead of just recycling it, the performance issues of using recycled rubber in tires are avoided.

Rubber composition containing enzyme-degraded rubber obtained by decomposing vulcanized rubber with a lignin-degrading enzyme. The composition has almost the same properties as a rubber composition made with virgin rubber. The enzyme-decomposed rubber is blended in an amount of 0.5-50 parts by mass per 100 parts of the other rubber components. This allows using recycled rubber while maintaining physical properties. The enzyme used is derived from white decaying fungi like basidiomycetes. The method involves pulverizing vulcanized rubber, decomposing it with the lignin-degrading enzyme, and then blending the enzyme-decomposed rubber with other rubber components.
