Everything You Need to Know About Carbon Black

Carbon Black is a commercial form of solid carbon that is manufactured in highly controlled processes to produce specifically engineered aggregates of carbon particles that vary in particle size, aggregate size, shape, porosity and surface chemistry. Carbon Black typically contains more than 95 % pure carbon with minimal quantities of oxygen, hydrogen and nitrogen.

In the manufacturing process, Carbon Black particles range from 10 nm to approximately 500 nm in size. These fuse into chain-like aggregates, which define the structure of individual Carbon Black grades.

What is Carbon Black

Carbon Black is used in a diverse group of materials in order to enhance their physical, electrical and optical properties. Its largest volume use is as a reinforcement and performance additive in rubber products.

In rubber compounding, natural and synthetic elastomers are blended with Carbon Black, elemental sulphur, processing oils and various organic processing chemicals, and then heated to produce a wide range of vulcanized rubber products. In these applications, Carbon Black provides reinforcement and improves resilience, tear-strength, conductivity and other physical properties.

Carbon Black is the most widely used and cost effective rubber reinforcing agent (typically called Rubber Carbon Black) in tire components (such as treads, sidewalls and inner liners), in mechanical rubber goods (“MRG”), including industrial rubber goods, membrane roofing, automotive rubber parts (such as sealing systems, hoses and anti-vibration parts) and in general rubber goods (such as hoses, belts, gaskets and seals).

Applications of Carbon Black

Besides rubber reinforcement, Carbon Black is used as black pigment and as an additive to enhance material performance, including conductivity, viscosity, static charge control and UV protection. This type of Carbon Black (typically called Specialty Carbon Black) is used in a variety of applications in the coatings, polymers and printing industries, as well as in various other special applications.

Actually, after oil removal and ash removal processing from tire pyrolysis, we can get high-purity commercial carbon black, which can be used to make color masterbatch, color paste, oil ink and as addictive in plastic and rubber products. Besides, after activation treatment, the carbon black will become good materials to produce activated carbon.

In the coatings industry, treated fine particle Carbon Black is the key to deep jet black paints. The automotive industry requires the highest black intensity of black pigments and a bluish undertones.

Carbon Black has got a wide array of applications in different industries

Small particle size Carbon Blacks fulfill these requirements. Coarser Carbon Blacks, which offer a more brownish undertone, are commonly used for tinting and are indispensable for obtaining a desired grey shade or color hue.

In the polymer industry, fine particle Carbon Black is used to obtain a deep jet black color. A major attribute of Carbon Black is its ability to absorb detrimental UV light and convert it into heat, thereby making polymers, such as polypropylene and polyethylene, more resistant to degradation by UV radiation from sunlight. Specialty Carbon Black is also used in polymer insulation for wires and cables. Specialty Carbon Black also improves the insulation properties of polystyrene, which is widely used in construction.

In the printing industry, Carbon Black is not only used as pigment but also to achieve the required viscosity for optimum print quality. Post-treating Carbon Black permits effective use of binding agents in ink for optimum system properties. New Specialty Carbon Blacks are being developed on an ongoing basis and contribute to the pace of innovation in non-impact printing.

What is Tire Recycling and How To Do It?

The old tires of your Subaru Forester are now worn out and no longer safe to be used on the road, says your mechanic. You’ve started shopping for new tires. But you wonder—what can you do with those old tires?

You can recycle it!

Tire recycling is the most practical and environment-friendly way of disposing of old and worn-out tires. Due to their inherent durability, large volume and environment and health risks, tires are one of the most problematic sources of solid wastes. Around the world, an estimated 2.5 million tires are thrown away yearly. With rubber recycling, tires can be given a new lease of life.

Benefits of tire recycling

Tire recycling can have numerous benefits not only for vehicle owners like you but also for the communities. For one, it can conserve landfill space. Because of their round and hollow shape, tires can take up significant space in landfills. Eliminating bulky items like tires can leave space in landfills for other things that cannot be easily recycled. There are many scientific papers about the benefits of processing, and if you were asked to write an essay, then you can contact this company with a request “buy essay” and a team of professional writers will help you

Tire recycling can also create new, beneficial products. Tire-derived fuel (TDF) is an example which is produced by subject scrap tires to high-temperature pyrolysis. This is reputed to be more energy-efficient than normal fuel. It also releases minimal emissions. Other useful products created from recycled tires are playground turf, railroad ties, and rubberized asphalt.

This process can also help in preventing the spread of diseases. Discarded old tires can provide a nesting place for rodents and mosquitoes. By recycling old tires, those pests can be eliminated. Consequently, diseases brought about by said animals can be prevented.

How to recycle tires

So, how do you recycle your old tires? One is to check with your local government about drop-off depots where you can bring your old tires for recycling. You may also bring those tires to household waste recycling centers.

These tires will then likely be packed and sent to processing plants, where they will be cut into smaller pieces by cut shredders. This is aimed at reducing the tire volume and creating a material that can be easily handled.

The end-product is a raw material that can be utilized for TDF, the most developed market for old tires in the United States. It is widely used in the country as a supplemental fuel by industries cement kilns, paper mills, and electric utilities, among others.

Tire shreds are then processed to remove the tire wire, which adds to the resilience, versatility, and strength of the tire. The wire is removed and recycled; often brought back to steel mills as these can be used in manufacturing new steel.

The remaining rubber is then screened to ensure that it is free from wires and other contamination. Afterward, the rubber is cleaned using water and other cleaning agents. Clean rubber is then packed and brought to other factories in need of rubber as raw material such as rubber shoe manufacturers.

Recycled rubber is also used in other ways such as ground rubber applications such as asphalt rubber, animal bedding, and synthetic sports field underlays. Asphalt rubber is widely used in Arizona, California, and Florida, for instance.

Other rubber by-products can be reused in various shapes and forms. For example, fiber and nylon make up nearly 15% of a tire. When extracted from old tires, these materials can be used in the manufacture of concrete, fiberglass, stucco, caret, and cleanup materials.

Rubber powder can also be derived from recycled tires. This high-performance but affordable material is used in creating sealing products, plastic, and rubber. It is a sustainable material with no adverse effects on

Other DIY ways to recycle tires

Yet DIY tire recycling can also come in other forms. You can reuse your old, worn-out tires in different ways.  One of the oldest ways to recycle old tires is to use them as tire swings. You can paint it first before hanging the tire on a tree. If you have many trees around your yard, you can hang a couple of old tires to create an entire swing set. This is an old-fashioned way to create a playset for your kids at home.

Tires can also be reused into tire climbers. Instead of spending several hundreds of dollars in a jungle gym, you can use old tires into a tire climber. Again, paint them first with bright colors. Bolt the tires together to make the tire climber safer for kids to play with.

You can also reuse old tires into a sandbox. This is particularly recommended if you have big tires like tractor tires. Put together several tractor tires in your yard and pain them. This is a nice way to thrill the kids during the summer. Check out cheap essay writing service to help your kids in their homework.

An old tire can also serve as a hose caddy. Instead of leaving your garden hose and increasing its chances of getting damaged, you can secure it with a hose caddy made of an old tire. This is simple to do—cut the tire in half and coil the garden hose inside it. You may even paint the tire so that it would match your outdoor décor.

Finally, you can reuse tires into planters. There may be some cutting involved so prepare tools such as saw and hammer. Again, painting the tire may be optional. You can make several planters depending on the number of old tires you have.

There are other creative tire recycling ideas that you may explore such as turning old tires into chairs, welcome mats, dog bed, and see-saws.

Conclusion

As you can see, old tires don’t have to end up in the landfills. Tire recycling is the best and most ecologically-sound way of disposing of old tires.

There are many ways to recycle old tires. You can bring your old tires to a household waste recycling center where these are collected and segregated before being processed into various by-products.

You can also recycle tires through DIY projects. From tire planters to tire climbers, the possibilities are endless as far as recycling and reusing old and worn out tires are concerned.

Agricultural Biomass in Malaysia

Malaysia is located in a region where biomass productivity is high which means that the country can capitalize on this renewable energy resource to supplements limited petroleum and coal reserves. Malaysia, as a major player in the palm oil and sago starch industries, produces a substantial amount of agricultural biomass waste which present a great opportunity for harnessing biomass energy in an eco-friendly and commercially-viable manner.

Peninsular Malaysia generates large amounts of wood and’ agricultural residues, the bulk of which are not being currently utilised for any further downstream operations. The major agricultural crops grown in Malaysia are rubber (39.67%), oil palm (34.56%), cocoa (6.75%), rice (12.68%) and coconut (6.34%). Out of the total quantity of residues generated, only 27.0% is used either as fuel for the kiln drying of timber, for the manufacture of bricks, the curing of tobacco leaves, the drying rubber-sheets and for the manufacture of products such as particleboard and fibreboard. The rest has to be disposed of by burning.

Palm Oil Industry

Oil palm is one of the world’s most important fruit crops. Malaysia is one of the largest producers and exporter of palm oil in the world, accounting for 30% of the world’s traded edible oils and fats supply. Palm oil industries in Malaysia have good potential for high pressure modern power plants and the annual power generation potential is about 8,000 GWh. Malaysia produced more than 20 million tonnes of palm oil in 2012 over 5 million hectares of land.

The palm oil industry is a significant branch in Malaysian agriculture. Almost 70% of the volume from the processing of fresh fruit bunch is removed as biomass waste in the form of empty fruit bunches (EFBs), fibers and shells, as well as liquid effluent. Fibres and shells are traditionally used as fuels to generate power and steam. Palm oil mill effluent, commonly known as POME, are sometimes converted into biogas that can be used in gas-fired gensets.

Sugar Industry

The cultivation of sugarcane in Malaysia is surprisingly small. Production is concentrated in the Northwest extremity of peninsular Malaysia in the states of Perlis and Kedah. This area has a distinct dry season needed for cost-efficient sugarcane production. Plantings in the states of Perak and Negri Sembilan were unsuccessful due to high unit costs as producing conditions were less suitable.

The lack of growth in cane areas largely reflects the higher remuneration received by farmers for other crops, especially oil palm. Over the past 20 years while the sugarcane area has remained at around 20000 hectares, that planted to oil palm has expanded from 600 000 hectares to 5 million hectares.

Other leading crops in terms of planted areas are rubber with 2.8 million hectares, rice with 670 000 hectares and cocoa with 380 000 hectares. Malaysia, the world’s third largest rubber producer, accounted for 1 million tons of natural rubber production in 2012. Like oil palm industry, the rubber industry produces a variety of biomass wastes whose energy potential is largely untapped until now.
