Tyre Recovery Association Announces Tyre Recycling Forum Day

The Tyre Recovery Association (TRA) has announced its Recycling Day forum will be held on 7 March 2018 at the Belfry Hotel & Resort, Wishaw.

Future of Tyre Recycling to be Discussed

The theme for this year’s event is ‘Tyre Recycling for Tomorrow’s World’ with guests from around Europe and from the UK discussing the direction of tyre recycling in the future.

Topics to be discussed at the forum include the NTDA and TRA’s Part Worn Tyre Accreditation Programme which will provide a fully-audited accreditation for tyres being offered for resale as part worn tyres. The programme will be introduced by Alan Bithell. Gary Walker from the Scottish Environment Protection Agency (SEPA) will also talk on the evolving partnership between TRA and SEPA. Howard Leberman from the Environment Agency will talk about the role of the regulator and discuss the proposed new charging regime for operators. NTDA chairman Stefan Hay will also talk about the importance of shared responsibility in the tyre industry.

Peter Taylor OBE, The Secretary General of the TRA, said: “The Tyre Recycling Forum is a chance for members of the tyre industry and recycling community at large to come together and discuss the direction in which tyre recycling is heading. Our programme of speakers shows our intention to provide information surrounding our sector and the partnerships we are developing to enable us to do this. 2017 was a successful year for the TRA as we launched the ‘kNOw Tyre Waste’ initiative and relaunched Responsible Retailing, as well as relaunching our website. This forum helps us look for ways to continue heading in the right direction in the years to come.”

In the past year, the TRA has launched two campaign initiatives and the relaunch of a brand new website. Responsible Retailing was launched to educate retailers on the importance of ensuring their waste is handled by an authorised waste carrier.

‘kNOw Tyre Waste’ was an initiative conceived to assist retailers in explaining the need for tyre recycling to consumers. It was designed to explain the different types of tyre waste, the examples of applications and the useful statistics surrounding tyre waste.

All members of the tyre and waste industries are invited to attend the free event. Those interested in attending can book via this online form or contact pr@tyrerecovery.org.uk

Murfitts Industries Offer Safe Crumb Rubber Infill

The UK’s Murfitt’s Industries has begun marketing what it claims to be the first 100 percent safe crumb rubber infill for sports surfaces.

New Step for Crumb Rubber Infill – Argued Murfitt

The product, called PRO-gran is described as a “Polymeric Infill that provides exceptional performance, it is the winning formula for 100 percent pitch safety, both for players and the wider environment. What’s more, it has been thoroughly tested and exceeds the EU’s toughest toxicology standards since it releases no heavy metals, PAHs, or microplastics.”

PRO-gran is a Polymeric Infill that combines the dynamic properties of rubber, which is then “coated in polyurethane to make it 100 percent safe”.

What differentiates Murfitt’s product from similar materials available elsewhere in Europe is the research and data backing up the product. Elastomer-coated rubber granules are already in use, in Italy in particular, but Murfitt’s has taken the extra steps to provide solid research data to back its claims for the product. That data is not always available from other producers of similar materials.

In fact, when talking to rubber processors, this is a point that Tyre and Rubber Recycling has been increasingly asking about. Do they know what they are selling? Can they specify the chemical make up of the rubber they are selling on? We believe that this is the way ahead for the ambient market – analysis and specification of the end material by chemical content as well as by size.

Green Carbon teams up with Caterpillar

Rome, Georgia-based Green Carbon Inc. has partnered with Caterpillar Power Systems to develop a sustainable system from the recycling of old tyres, belting and rubber tracks.

Fusion of Company Resources to Utilise Gas By-Product

Called a Bio-cogeneration System, Green Carbon’s Thermal Vacuum Reactor System utilises a custom designed generator produced by Caterpillar to capture a synthetic gas by-product of the recycling to power the generator.

“We were looking for a way to use the excess gas that is produced in the system in an environmentally friendly way,” said Green Carbon co-founder Phil Wilson. “I approached not only Caterpillar, but several other companies and Caterpillar was the one that was able to develop the generator so that it would work off our gas.”

The generator is a variation of one of Caterpillar’s existing generators, adapted tyo burn the off-gas from Green Carbon’s process.

“Essentially you could put it out in the middle of a corn field and run it without anything else, except for the tyres,” said Andrew Taylor, environmental management system for Green Carbon Inc. “It’s perpetual, the whole thing is powered by itself as long as you keep putting tyres in.”

Green Carbon Inc. is a co-owned company with OTR Wheel Engineering of Rome. OTR has had a long relationship with Caterpillar.

“They got with us and we finally got the design right, and we finished all the testing and now have a massive natural gas-burning generator. They cut off the external power and it runs off itself,” Taylor said. “The entire system produces its own energy and never needs any kind of virgin material, meaning natural gas or diesel or electricity from an external source.

A half dozen of the units are in use at Fort McMurray in the area of oil sands in extreme northern Alberta, Canada. The reactors are used to recycle massive earth-moving and mining tyres.

A 63-inch tyre, can be reduced to 588 gallons of oil, 3,500 pounds of carbon black and 1,500 pounds of steel. The largest reactor can burn two of those tyres at the same time in a process that takes 16 hours from start to finish. The process also produces and captures more gas than it takes to fuel the process.

“Our latest units that are operating in Fort McMurray are producing about 180 percent of the synthetic gas that is required to run the process,” Wilson said. “There is an enormous surplus of gas which in the winter they can use for heating, but in the summer they just have to store it. Co-generation will use that gas up supplying not only the power they need to run their plant but also sell it back to the grid.”

Co-founder Fred Taylor has indicated that each of the large reactors is capable of eliminating enough tyres to result in the creation of about 36,000 gallons of oil.

RWM Acquired by the PRYSM Group

Independent organiser The PRYSM Group has acquired the industry-leading recycling and waste management trade show RWM from Ascential PLC.

Key Addition to PRYSM’s Environmental Division

The PRYSM Group has announced that RWM in partnership with CIWM, the UK’s leading recycling, energy, water and waste management show, has joined its Environmental Division, which already includes The European Contamination Expo Series, Hazardous Waste Expo, Land Remediation Expo, The Flood Expo and The Marine & Coastal Civil Engineering Expo. RWM, the only UK event that brings together the entire industry, was acquired from Ascential plc.

Commenting on the acquisition of RWM, Event Director Nick Woore, said: “RWM is undoubtedly the leading exhibition in the global resource management sector, so to be able to add the show to our already incredible portfolio is extremely exciting.

“Waste, recycling and resource management is crucial to all of our lives and the significant contribution that this dynamic and innovative sector can make to the economy is increasingly being recognised by governments and industry. Running this event is an honour we are not taking lightly, and we will ensure that this exhibition leads the way for the industry tasked with delivering a sustainable future for our country.”

“This is an exciting development for RWM and CIWM looks forward to working in partnership with PRYSM to ensure that the show goes from strength to strength as the premiere showcase for the resources and waste management sector,” said CIWM chief executive Dr Colin Church. “We welcome PRYSM’s decision to invest in expanding its environmental business and there are clear synergies with other events in the PRYSM stable.

Dates for RWM 12th & 13th September 2018

Attendance at the RWM had been falling and some sectors of the waste market had not been represented at the show. The organisers plan on co-exhibiting with their existing events, the Flood Expo, The European Contamination Series (including Hazardous Waste Expo, Spill Response Expo and Land Remediation Expo) and Marine & Coastal Civil Engineering will move to sit next to a new look RWM.

Each of these additional exhibition areas will hold some interest for the tyre recycling sectors as there is potential for tyre use in all three areas. This gives some hope that the tyre recycling sector may have an opportunity to become involved at the event to promote the work done by the sector.

ISRI Supports Call for Scientific Assessment

ISRI Supports Call for Scientific Assessment

Recently, the US Council of State Governments (CSG) approved a resolution calling for scientific evidence to be paramount when assessing recycled rubber play surfaces.

Sen Jeremy Miller Looking for Answers into Rubber Play Surfaces

The resolution was presented to the CSG Energy & Environment Committee by Minnesota State Sen. Jeremy Miller in the context of recent debate surrounding the use of recycled rubber, especially given unsubstantiated reports regarding health concerns, ISRI notes.

The resolution, “Resolution on Utilising Science-Based Evidence Related to the issue of Installation of Artificial Turf Athletic Fields Made of Recycled Rubber Infill,” calls for science to take precedence over conjecture in assessing recycled rubber and for the timely completion of the federal multiagency study that is currently underway.

“ISRI strongly supports and applauds the passage of this resolution, which will undoubtedly raise awareness among state legislators around the unsubstantiated nature of current claims made in the debate over recycled rubber,” says ISRI President Robin Wiener. “There are currently more than 90 peer-reviewed scientific studies demonstrating there is no increased health risk to athletes playing on artificial turf containing recycled rubber, without credible evidence to the contrary, and it is critical that this reality be made widely known to policymakers.”

Miller says, “As a parent and a legislator, creating a safe environment for our children to play in is a top priority. Recycling tyres cleans up and preserves the environment for current and future generations. As we encourage children to take part in healthy activities and exercise more, the material from these recycled tyres is a source for safe, accessible turf. Credible science has demonstrated this time and time again. It is imperative that fellow state and local lawmakers carefully review the facts when making any key decisions regarding our children and jumping to conclusions not supported by science.”

Doublestar Enters Rubber Recycling

According to press reports, China’s Doublestar broke ground on its plant for scrap rubber recycling in Zhumadian in December.

Big Development for Doublestar

Located in the city’s Runan County, the site covers 2.15 million square feet and will be able to handle 200,000 tons of scrap rubber annually when fully operational. The company has earmarked $92.7 million for the project.

The site contains two phases, each including 100,000 tons of annual capacity. Phase 1 is scheduled to be operational by the end of 2018, Doublestar said.

The firm said the site will be the world’s first Industry 4.0 site for scrap rubber recycling, with smart technology used in processes such as sorting, rinsing, drying, conveyance, pyrolysis and storage. The plant also boasts zero emission using Doublestar’s waste treatment technology.

With machinery developed by Doublestar, the site will be able to fully recycle scrap tyres, generating primary oil, carbon black, steel wire and gas, the last of which will be used to fuel the plant.

The company plans to build at three additional sites as well as a research centre.

rCB from Enviro for Tyre Manufacturer

A leading Sri Lankan tyre manufacturer has placed a first order for Enviro’s recycled carbon black, EnviroCB, for immediate delivery.

Orders Picking up for Enviro CB

“Initially the order volume is small, but is expected to increase significantly over time. The customer is a global manufacturer of tyres and rubber applications and this order relates to industrial tyres”, says Thomas Sörensson, CEO of Enviro.

The order comes after completing thorough material tests. The tyre sector is the Holy Grail of pyrolysis firms and this is a huge step for Enviro but also a huge step for the rCB sector as its products are starting to gain recognition and acceptance in the tyre sector.

“For us, the increasing demand of recycled material as a substitute for virgin carbon black, is the most important market signal. Now that our order build-up is growing, more will see the benefits of Enviro’s patented technology and the plants we sell.”

The delivered EnviroCB will be used for industrial tyres manufactured in Sri Lanka.

“Aiming for high manufacturing growth, Sri Lanka is investing in the rubber industry, which makes the country a very interesting market for us,” says Thomas Sörensson.

Industry Feigns Shock as China Refuses Plastics Waste

Industry Feigns Shock as China Refuses Plastics Waste

China’s latest steps to improve its environmental condition and deal with its own waste include a ban on the import of plastic waste. For the UK that means that the country has to find some way of disposing of some 500,000 tonnes of plastic waste and other materials.

Recycling Association Looking for New Alternative to Plastic Waste

“It’s a huge blow for us… a game-changer for our industry,” said Simon Ellin, the CEO of the UK Recycling Association.

“We’ve relied on China so long for our waste… 55% of paper, 25% plus of plastics,” he told the BBC.

Environment secretary Michael Gove admitted he should have reacted faster to the issue and says the UK’s long-term goal is to reduce the amount of plastic in circulation.

According to the Telegraph, UK recycling firms are looking to other markets such as Malaysia and Vietnam to take up the excess volume created by the Chinese block on imported waste.

The reality is that the UK needs to develop a true recycling culture and develop the infrastructure required to deal with its own waste. Any shift in destination to Malaysia or Vietnam, or India can only be temporary as these states begin to tackle their own waste management issues.

We, in the UK, need to face the reality that markets for our waste are closing, and we need to do something to deal with our waste sooner rather than later.

Cemex Takes in Tyres from Queretaro

Cemex in Mexico, is taking used tyres off the streets of Santiago de Queretaro, Mexico, thanks to a local authority initiative to clean up tyres left on vacant urban land and in the city’s drainage system.

Initiative Helps Santiago de Queretaro

The Mayor, Marcos Aguilar Vega, announced that up to 3905 wheels were collected during the first “Llantaton 2017”, held in early December. These were added to those collected throughout the year.

“In cooperation with the tyre companies and the cement factory these programmes of tyre collections have helped clean up the environment of Queretaro,” said the Mayor.

He said that in the first week of December, 7000 tyres had been delivered to Cemex for processing.

Salvadori MT REX Demonstrates the Economic Benefit of Waste Tyre Recycling in the Mining Industry

Salvadori MT REX Demonstrates the Economic Benefit of Waste Tyre Recycling in the Mining Industry

Our planet has over 6,000 operating surface mines working around the clock to provide the raw materials that fuel our globe’s economic development. These mines have been operating for an average of 23 years, and 20% have been working for greater than 40 years. To operate efficiently, these surface mines utilise a wide range of equipment, such as dumpers, loaders, and other wheeled vehicles.

Salvadori Introduces New Machinery for Mines

A sample of 1,300 of the mines revealed a staggering 38,000 mining trucks in operation. This massive fleet of trucks is equipped with extra-large tyres, up to a 63” rim, which weigh up to 6 tons, and have an outside diameter of 4.1 metres. A mining dumper is typically configured with 6 wheels to tackle the demanding operating conditions, and each of these tyres has an operating life of 5 to 10 months. Once these tyres can no longer be repaired or retreaded, they require disposal. Some quick maths yields an estimated annual consumption of one million mining truck tyres, which equates to 5 million tons of material to be managed. Extending this analysis to the wide-ranging fleet of mining vehicles results in a mind-numbing eco-liability for today and future generations.

In order to address the issue Salvadori has introduced MT-REX™, a new patent-pending OTR tyre downsizing system. The MT-REX delivers considerable benefits to mines and mine service companies. Consisting of a single integrated piece of equipment, the MT-REX is both compact and mobile as well as requiring only one operator. The machine also offers a particularly fast processing time, being capable of downsizing a 63” tyre in less than one hour and consumes up to 50% less energy than an excavator equipped with a shear.

Downsizing is the first step in recycling a waste tyre, whereby the tyre is cut into multiple sections that can be processed by a traditional shredding line. Salvadori MT-REX is the world’s first fully-integrated OTR tyre downsizing machine. Following downsizing, the shredding process takes place. In the shredding step, the waste tyres are separated into components: steel, textiles and granular rubber. The third and final step is converting granular rubber into coloured and moulded products with other Salvadori equipment. These three steps of downsizing, shredding, and conversion close the loop of the circular economy and enable the transformation of waste to value.

Salvadori MT-REX is the first fully automated system capable of managing tyres up to 63” rim diameter and provides a continuous flow of clean and standardised sized tyre chunks. MT-REX can be operated by a single operator by means of a forklift … no overhead crane is necessary. Whole OTR tyres are loaded in the front-end, and pre-determined sized tyre chunks roll down the MT-REX conveyor belt.

The MT-REX completes four downsizing jobs in a single piece of equipment:

Loading

A forklift places the end-of life OTR tyre in the cradle. This cradle can safely accommodate smaller tyres with a 1.8 metre outside diameter (OD) to a large tyre’s 4.1 metre OD. In other words, virtually any OTR tyre can be loaded.

The cradle’s opening and closing movement is performed by oil hydraulic cylinders. In order to safely load the tyre, proximity sensors help the forklift operator position the OTR tyre.

Positioning

This positioning unit makes 3 movements:

– The unit’s mandrel probes the inside of the tyre and pivots 90 degrees. This places the tyre on a horizontal plane.

– The unit moves horizontally to automatically position tyres with different diameters at different distances from the cutting unit.

– Finally, the unit raises the tyre to the pre-programmed height.

These three movements place the tyre in the most-efficient cutting location based on each tyre’s unique geometry.

Then during the cutting operation, after each cut is performed, the tyre is automatically rotated by a prescribed number of degrees to prepare for the next cut.

This unit is moved by oil hydraulic cylinders. Depending on the tyre size, the positioning unit is fitted with a mandrel designed to keep the tyre in place during the cutting operation.

Three mandrels are available for varying rim dimensions;

– Small ranges from 33-35-39″ rims

– Medium ranges from 45-49-51″ rims

– Large ranges from 57-63″ rims

If future tyres exceeding 63” rim are developed, MT-REX’s™ configuration can be expanded.

Cutting

The cutting unit performs tyre downsizing with a uniquely designed 1.5 metre length blade profile operated by high pressure double effect oil hydraulic cylinders.

The cutting depth and speed are customisable based upon tyre geometry, tread dimensions and other parameters. This enables operators to select the optimum size downsized tyre chunks while maximising cutting speed.

The cutting blades have been designed to be quickly and easily removed for maintenance and replacement.

Conveying

The downsized pieces are automatically removed by an electrically operated conveyor belt. This unit can be extended and connected to an external container or to the input feed of a traditional tyre shredding line.

The integrated conveyor keeps tyres from being contaminated by foreign objects such as rocks, which could adversely affect shredding equipment.

The MT-REX is pre-programmable by PLC and a touch screen HMI management system. The PLC allows the possibility of storing a sufficient number of programmes (recipes) for the processing of different types of tyres. In addition, the MT-REX can also be operated with a radio frequency remote.

Power to the MT-REX is supplied by 400V-50Hz-3 phases + neutral + grounding.

MT-REX is powered exclusively by electrical motors. Diesel fuel is only required if an electrical generator is used. The electrical power is an environmentally sustainable (no exhaust emissions), low-cost solution. Standard energy consumption is 40kWh, which translates to a few Euros per hour of electric energy to operate the MT-REX. Even if the electrical power is supplied by a diesel generator, the fuel consumption is less than 50% of an excavator equipped with a shear.

Safety is uncompromised with the MT-REX. Fixed guards surround the cutting area, with two side gates enabling maintenance operations. These maintenance gates have an electric safety lockout feature to prohibit access during operation. Additionally, optical safety barriers protect the loading site. The system is compliant to European Machinery Directive 2006/42/EC.

Optional internet-ready webcam connection is available to remotely diagnose the system and perform routine maintenance.

Despite its weight of nearly 42 tons and a footprint of 7 X 14 metres, MT-REX is modularly configured, making relocation to an alternative site easy in only two days (one day for disassembly and one day for re-assembly).

With a processing time of less than one hour for a 63” tyre, MT-REX continuously operated can downsize more than 7,000 tyres per year and consistently feeds more than 35,000 tons per year of clean and regularly cut pieces to a traditional shredding line. All of this can be completed with only one operator who is safely located behind the gates.

Comparing the MT-REX to alternatives makes economic and safety decisions easy. For example, an excavator with a shear will burn over 210,000 litres of fuel per year and require additional equipment to move the highly irregular downsized rubber to the following process. This operation must be staffed by multiple people per shift, all who are in close proximity to the downsizing process involving multi-ton tyres.
