Our 2018 Review

A Look Back at Our News & Blogs from 2018

BREXIT and concerns about plastic waste have dominated the news in 2018.  Despite the BREXIT pessimism, UK exporters continue to export and the plastics industry is working hard to pacify environmentalists.  2018 has been another great year for Bunting Europe and we look back on the past twelve months of our news and blogs.

January

WEEE E Waste2018 started with the announcement of our attendance at the 17th International Electronics Recycling Congress (IERC) in Salzberg, Austria.  After the event, we write a review highlighting that the congress recognised that changes in e-waste management are needed.  Secondary electronics continues to be a source of many valuable and precious metals.  With technology such as the Stainless Steel Magnetic Separator, it is possible to recover printed circuit boards (PCBs) from waste.

Towards the end of January, we listed the record number of exhibitions and conferences being attended in 2018.  It was going to be another busy 12 months.

We also announced of search for a representative in German to help develop business in the recycling sector.  This search remains ongoing.

February

The UK Government had announced that 2018 was going to be the Year of Engineering.  We announced our support, highlighting the need to encourage young people to seek a career in an exciting and ever-changing industry.

RWM Digital Masterclass 2018_02_06In February, we were invited to attend a RWM digital masterclass at the Google headquarters in London.  The RWM exhibition had been acquired by PRYSM Media and they wanted to show how they were going to breathe new life into the struggling event.

A week later we announced our continued support for RWM with confirmation of exhibiting in 2018.  We had taken the opportunity to book one of the premier stands, immediately opposite the entrance to the show.  With our extensive range of Bunting and Master Magnets metal separation equipment, we wanted to demonstrate that we are now one of the major suppliers to the recycling industry.

One of our large ongoing export orders is supplying In Line Magnets to a baby food producer in Germany.  By February 2018, we had supplied 42.  The In Line Magnets remove ferrous metal contamination.

Our final blog of the month focused on how contamination is hindering the recycling of plastic.  Plastic recycling companies face huge challenges due to unnecessary and avoidable contamination.

March

Our first blog in March asked whether recycling in the UK was reaching crisis point.  What were the politicians going to do with recycling targets unlikely to be achieved and the ongoing pressure to deal with plastic waste?

Mark Harris Bunting Magnetics EuropeWe announced the expansion of our sales team with the appointment of Mark Harris, a field sales engineer for the Southern part of the UK.

In February 2018, Youngs Seafood had recalled fish cakes due to the possible presence of metal and plastic.  We investigated how this could occur and what measures were needed to prevent re-occurrence.

In March, Bunting and Master Magnets were announced as the joint headline sponsors of the WASTE’18 exhibition.  We also announced that Bunting and Master Magnets were exhibiting high intensity magnetic separators at the Ceramitec trade show in Munich, Germany.  Master Magnets has a global reputation in the ceramics and mineral processing industries and Ceramitec is one the premier world exhibitions.

In a move to pacify environmentalists, the UK Government announced a new UK drinks container recycling strategy in March 2018.  However, the announcement raised more questions than answers and we assessed whether the proposed changes would make a difference.

April

In 2017, the UK Food Standards Agency reported six cases of food being recalled due to metal contamination.  We reviewed all six cases and assessed why the problems occurred and how they could have been prevented.

Ceramitec 2018

Ceramitec was held between 10th and 13th April 2018 and proved to be a great success.  An order for two Master Magnets Electromagnetic Filters was placed at the show by a Turkish ceramics producer.

In Telford, UK the Polymer Training and Innovation Centre added a Bunting Magnetics Drawer Filter Magnet to the range of equipment at their plastics manufacturing training facility.  This extended the range of equipment used to train the next generation of plastics engineers.  Later that month, the Polymer Training and Innovation Centre held the Technivation conference, attracting delegates from across the UK plastics sector.

In April, we had conducted 3 separate Magnetic Separation Audits at UK food companies.  Each audit using the Pull Test assessment method of determining magnetic strength by measuring the force needed to remove specific metal items from the surface.  The audits found that several of the Magnetic Separators were no longer fit for purpose due to damage, age or location.

May

We announced our support and sponsorship for the Tŷ Hafan #5in55 Mountain Challenge.  Between the 5th and 7th July 2018, a group of Dads, whose families have been supported by Tŷ Hafan, were aiming to climb and travel between five UK mountains in a maximum of 55 hours.  We had been thrilled to sponsor the Ben Nevis leg of the challenge.

Bunting Master Magnets IFAT 2018

Our next exhibition was 2018 was the IFAT tradeshow in Germany.  IFAT was the largest waste and recycling focused event in Europe and an ideal location to demonstrate the Stainless Steel Magnetic Separator and Eddy Current Separator.  The show proved to be exceptionally successful.

June

In early June, the UK Food Standards Agency announced the recall of 59 pastry products due to the potential presence of metal.  This affected products being sold by major UK food retailers Tesco, Aldi and Nisa.

Bunting Magnetics Drawer Magnets at Ecovyn

The busy exhibition schedule continued with a review of the Hillhead 2018 event.  Master Magnets had exhibited at the show for decades and this was the first joint stand.  The show was another success with orders were secured on the stand.

Plastic waste returned to our news with a review of FF Drawer Filter Magnets installed at EcoVyn in Wrexham, UK.  Since the installation of the magnetic separators, EcoVyn had reduced their waste by 94%.

July

We started with a review of the WASTE’18 show where we were offering companies a ‘Metal Separation MOT’.  The exhibitions train kept rolling and our next blog reviewed the CARS 18 exhibition at NAEC in Stoneleigh, UK.

Plastic waste and recycling hit the headlines again in July.  Brussels-based Plastic Recyclers Europe (PRE) and the Association of Plastic Recyclers in Washington, USA concluded that there are four conditions that define a plastic product as being “recyclable”.  This appeared to be a logical and helpful proposal that is yet to be accepted by the EU and the UK.

August

With the RWM show being less than 1 month away, we reviewed our attendance at the show.  With such a prominent stand, we wanted it to be very interactive and turned it into a metal separation test centre.

metal_in_sugar-1853-e1533716896631.jpg

The UK Food Standards Agency announced the latest metal-in-food safety alert, reporting that Tereos UK had recalled Granulated Sugar due to the presence of small metal pieces.  We reviewed the challenges of removing metal from sugar.

In August, Skip Hire Magazine featured an article we had written entitled ‘Metal Detectors Detecting More Than Treasure‘.  The article was re-published as a blog and looks at how Metal Detectors are used widely in the waste and recycling industry.

In anticipation of the RWM waste and recycling show in September, we reviewed 3 facts about plastic packaging waste.  These included how much plastic waste is produced, the present recycling rate, and the existing plastic recycling plant infrastructure.

September

RWM 2018 Exhibition

The rejuvenated RWM18 proved to be a huge success for the organisers and Bunting.  There was a constant flow of traffic on the stand with a great deal of interest in the working Stainless Steel Magnetic Separator and Eddy Current Separator.

Later in the month, we celebrated the 2018 Recycle Week (24-30 September) by reviewing three successful plastics recycling projects.

October

In October 2018, the Master Magnets brand celebrated its 40th anniversary.  Over 40 years, Master Magnets has developed into one of the world’s leading suppliers of magnetic separators and metal detectors to the mineral processing, ceramics and recycling industries.

Our technical article ‘Practically Measuring Magnetic Separator Strength‘ reviewed practical and accurate methods of testing magnetic separators.  This method is used by many food processing companies as part of an annual audit of their processing equipment.

Bunting Europe Health and Safety Committee

We had reason to celebrate in October, with the announcement that we had been awarded the ISO45001 international standard for occupational health and safety (OH&S).  This relates to all activities on their European manufacturing headquarters in Berkhamsted, United Kingdom.  Congratulations to our Health and Safety Committee!

One extensive Magnetic Separation Audit undertaken in 2018 was for Jordans Dorset Ryvita at their factory in Poole, UK.  The 3-day audit reviewed 52 different Magnetic Separators.

There was more export success with the sale of 24 Drawer Filter Magnets to a plastics producer in France.  The sale had been secured by Bunting’s local representative BMS.

November

Despite the growing unrest about BREXIT, there was still positive news about business overseas.  15 Magnetic Liquid Traps were sold to fruit juice producers in Spain.  Additional orders are expected in 2019.

Tekemas Team at Scanpack 18

Dave Hills and Tom Higginbottom provided support to local representative Tekemas at two trade shows in Scandinavia.  The Scanpack show in Goteburg, Sweden and FoodTech in Herning, Denmark provided an opportunity to gather information on the local market and provide training.

Plastic waste returned to the news with a blog that was first featured as a headline article in the British Plastics & Rubber magazine (Nov/Dec 18).  The article was titled ‘The Changing Face of Plastics Recycling‘ and assessed changes made in 2018.

December

Eder_Design_Training_Visit_4489Laura Joubert from our South Africa representative Eder Design traveled to the UK for product training.  Over a week, Laura had the opportunity to meet both the Master Magnets and Bunting teams, whilst receiving training on Magnetic Separators and Metal Detectors.

As 2018 draws to a close, we reviewed our first overseas exhibition of 2019:  ArabPlast.  We attended ArabPlast, Dubai, UAE in 2017 and it proved to be a big success with orders secured on the stand.  We will again be exhibiting in 2019 (5-8 January 2019).

We hope you have enjoyed reading our news and blogs in 2018.  If there are any topics that you would like reviewed, then please get in touch and send an email to Paul our press officer (press@buntingeurope.com).

Bunting Awarded ISO 45001 Standard

Priority Given To Health and Safety

In October 2018, Bunting Magnetics Europe successfully achieved the new ISO 45001 international standard for occupational health and safety (OH&S).  This relates to all activities on their European manufacturing headquarters in Berkhamsted, United Kingdom.

iso45001_infographic

To combat injuries in the workplace, ISO has developed a new international standard, ISO 45001, published in March 2018.  This covers occupational health and safety management systems.  ISO 45001 provides organisations with a framework for employee safety, reducing workplace risks, and creating better and safer working conditions all over the world.

Bunting has achieved the new standard directly and in a short period of time.  This was achieved without modifying and migrating from existing processes.

“As a team, we felt that it was important to have a fresh review of the whole process,” explained Denis Elkins, Bunting’s Health and Safety Manager.  “By effectively starting from scratch, we were able to implement processes without compromise.”

Bunting is the first company of their kind to be awarded the ISO 45001 standard.

“We are very proud of our achievement,” explained Simon Ayling, Bunting’s Managing Director.  “From the outset, we knew that this would be a challenging objective.  However, our newly formed Health and Safety committee has been outstanding.  I wish to thank everyone for their hard work in making this happen.”

Master Magnets Brand Celebrates 40 Years

Celebrating Long Term UK Manufacturing Success

In October 2018, the Master Magnets brand celebrates its 40th anniversary.  In that time, the Birmingham based Magnetic Separator and Metal Detector manufacturer has developed a reputation as one of the leading technology companies in the recycling, mining and mineral processing industrial sectors.

Adrian Coleman (left) and Simon Ayling (right) on the Bunting stand at RWM18 exhibition

Since January 2017, the Master Magnets brand has been owned by Bunting Magnetics.  Bunting Magnetics is one of the world’s leading suppliers of Magnet related technology.  The European manufacturing headquarters are based in Berkhamsted in Hertfordshire, UK and they have an extensive overseas network of distributors and marketing agents.

Master Magnets was founded in 1978 by Geoff Worley, a qualified engineer with fifteen years’ experience in the magnetics industry.  The company grew steadily throughout the 1980s despite the economic challenges and was perfectly positioned for the increased demand in the early 1990s.

At the time, there was high levels of investment in the UK coal industry and globally located mineral processing projects.  Using his considered knowledge, Geoff and his team of engineers developed a range of magnetic separators specifically for those key industries.  For the coal and mining industries, they developed large Electro Suspension Magnets which would be suspended over conveyors to remove large tramp metal such as pit props and bars.  The drive in Mineral Processing was for higher purity non-metallic minerals.  The team designed the Induced Roll Magnetic Separator (IMR) and established a laboratory where clients could test materials.

As demand increased, the company expanded and made investments in new manufacturing technology including heavy-winding gear for ever-larger Electro Suspension Magnets.  A bespoke super-strength magnetiser, weighing over 14 tonnes, was acquired, one of the largest of its kind in the world.

Master Magnets Overband Magnet on a mobile shredder

Master Magnets also developed a reputation for manufacturing Permanent Overband Magnets.  Recycling was in its infancy, but several UK businesses were developing large mobile screens and crushers for construction and demolition sites.  Master Magnets worked with the companies to develop a compact but powerful Overband Magnet that needed limited power (the only power required is to operate the belt which can be done hydraulically or electrically).  Master Magnets continue to be one of the world’s largest producers of the Permanent Overband Magnet.

The Master Magnets brand became globally recognisable as export sales increased.  In 2003, Master Magnets acquired the company Integrated Recycling Systems and relocated to Redditch.  Further acquisition took place in 2005 with the purchase of the Metal Detection business.  This further expanded their manufacturing portfolio.  Customers were now able to purchase their metal separation and detection solution from one supplier.

Master Magnets continued to evolve and expand.  Worley took partial retirement and handed the reigns of the business to Adrian Coleman.  Coleman had started his career at Master Magnets in 1984 as an apprentice and witnessed the evolution of the company.

Adrian Coleman with Geoff Worley in 2008

“Master Magnets gave me the opportunity to develop my engineering career,” explained Coleman.  “In 1988, they supported me through a four year Mechanical Engineering course at Birmingham University.  This gave me the necessary engineering skills to join the design office.  As the company grew, I took up the position of Production Manager, before becoming Managing Director in 2008.”

In 2017, Worley agreed to sell the Master Magnets business to Bunting Magnetics.  He foresaw the investment needed to maintain Master Magnets’ reputation as a global leader and identified Bunting as the ideal partner.  Coleman was appointed as the General Manager, an important step that ensured business continuity.

“Master Magnets has developed a long-standing strong identity and reputation as a leader in metal separation technology,” said Simon Ayling, Bunting Magnetics Europe’s Managing Director.  “The acquisition means that we can invest in their manufacturing facility in Birmingham and in the development of new separation technology.  When Geoff [Worley] founded the company, his aim was to produce well-engineered equipment to solve metal contamination and separation problems.  That challenge has been passed onto us and we are excited by the future.”

A Rejuvenated RWM Exhibition

Busy Stand for Bunting Magnetics at RWM

At this year’s rejuvenated RWM Exhibition (NEC, Birmingham, 12th – 13th September), the Bunting Magnetics and Master Magnets stand proved to be a great success.  Being positioned in a prime stand in front of the entrance, and with working metal separators on the stand, visitors were drawn to see the latest developments in magnetic separation technology.

RWM 2018 Exhibition
Stainless Steel Magnetic Separator in action

In January 2018, Prysm Group announced that they had taken on the flagging RWM exhibition.  Attendance of the RWM exhibition in 2017 had been poor and many exhibitors had lost faith with the event.

At an event in the Google headquarters in London, RWM exhibition manager Nick Woore announced their intention to inject new life into the show.  The plans sounded positive, although there was still a great deal of doubt from many exhibitors.  In fact, in 2018 the number of exhibitors were lower than in 2017, but visitors numbers were higher.

“It was great to see people queuing outside the entrance on the first morning of the exhibition,” said Dave Hills, Bunting’s Head of Sales.  “As soon as the doors opened, our stand was full of visitors.”

Bunting had two operating production-sized metal separators on the stand:

Dave Hills also gave two presentations on ‘Stainless Steel Separation in Modern Day Recycling’.

RWM 2018 Exhibition

“Being able to show visitors the separation capabilities of the equipment was vitally important,” explained Hills.  “This made it easier to relate to their metal separation requirements.  Following the exhibition we will be conducting tests at our Master Magnets Redditch laboratory, where we can confirm the separation capabilities.  It is going to be a busy few months.”

Hills also explained the importance of a successful RWM.  “Recycling and good waste management is no longer an option but a necessity and it is essential that there is a UK based trade event.  We are looking forward to hearing how the organisers plan to further develop RWM for 2019.”

3 Facts About Plastic Packaging Waste

Latest 2016 Waste Recycling DEFRA Data

The UK’s largest recycling exhibition, RWM, takes place on the 12th and 13th September 2018 (NEC, Birmingham, UK).  Leading up to the show, we wanted to review three key facts relating to the latest DEFRA data (from 2016) on plastic packaging waste (published in February 2018).

Waste Drinks Containers-9048

The Amount of Plastic Packaging Waste

UK households generated 1,015,000 tonnes of plastic packaging waste in 2016.  This is actually 12% lower than in 2012, although the amount has been relatively stagnant since 2103.  In 2016, 20% of all packaging waste was plastic (by weight), although this percentage would be far higher if measured by volume due to the low bulk density of the material.

A Rising Recycling Rate

45% of plastic packaging was recycled or recovered in 2016 compared with 25% in 2012.  The 2016 figure is higher than the EU target of 22.5%.  Since the beginning of 2018, the UK Government has set a new recycling and recoverable target of 57% by 2020.  This means that new strategies are needed to raise the rate by 12% in just four years.

Plastic Packaging Recycling Rates

However, there remains a question about what to do with the plastic once it has been recovered.  The UK still exports a large proportion of its waste, but this is still classed as being ‘recovered’ and is included in the 45%.  Since China closed their doors to waste, plastic waste has being shipped to countries around the world, including Malaysia, Thailand and Vietnam.  This is not a sustainable solution, but it not reported in the statistics.  An increasing amount of plastic waste is expected to remain in the UK and it is unclear how it will be managed.

Plastics Recycling Plants

It is widely accepted that there are not enough plastic recycling plants in the UK.  In the past, it has been difficult to economically operate a plant with high costs associated with equipment investment and site difficulties due to the flammable nature of plastic waste.

FF Drawer Filter Magnets (supplied by Bunting Magnetics Europe Ltd) removing metal from plastic waste to enable recycling

One successful plant is located near Wrexham in North Wales where EcoVyn process 1,000 tonnes per month of good quality plastic waste.  EcoVyn installed several Drawer Filter Magnets to remove ferrous metal contamination from the granulated plastic.

The Future

There has been a huge change in the public perception of plastic waste since the showing of the BBC series Blue Planet II in 2017.  This has forced politicians to start taking action and it will be interesting to see the level of political and governmental engagement at the RWM exhibition.

Metal Detectors Detecting More Than Treasure

Technology Keeping Waste Metal-Free

The BBC television series Detectorists has significantly increased the public’s awareness of metal detectors, but many people remain unaware of their importance in the recycling of waste materials.

399

Although the size and design of metal detector used in the recycling industry may be different to those used by the enthusiasts on the television show, the basic concept is the same.  When an electric current is passed through the coil of a metal detector, it creates a magnetic field.  If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own.  A separate control recognises that the new magnetic field has changed the metal detector’s magnetic field and identifies that there is metal present.

Metal Detectors are becoming increasingly important in the recycling industry.  Magnetic Separators and Eddy Current Separators are widely used to remove liberated ferrous, non-ferrous and even some stainless-steel metals, but are unable to separate metals that are imbedded in material or are unresponsive to these types of metal separators.

This is particularly important in recycling operations where the waste material is large in size and needs to be shredded or granulated.  A common location for the Metal Detector is on the conveyor prior to size reduction, where it identifies the presence of any metal that may damage the shredder or granulator.  The effect of metal damage can be costly in terms of repair and also downtime.  Typical waste materials include plastic, wood, and demolition waste.

There are primarily two different types of Metal Detector suitable for detecting metal in such conveyed material.  The Underbelt Conveyor Metal Detector is ideal when handling larger materials of variable shapes and sizes and the aim is to detect larger metal.  Two different coil designs mean that the Metal Detector is suitable for belt widths from 100mm to 1200mm.  This design of Metal Detector identifies and then stops the conveyor belt.  Operators then locate and manually remove the metal contamination.

The second type of Metal Detector surrounds the conveyor belt.  This increases the detection sensitivity and is also needed when there is a deeper burden depth on the conveyor.  There are various coil configurations, such as the QDC, QTA, and TN77, and the selection is based upon each application.

Once the waste has passed through the process of size reduction and separation, Metal Detectors are commonly used to check that metal is not present in the final product.  In some applications, the material will still be conveyed and so previously mentioned designs are used.  However, in applications where the particles are now significantly smaller different designs of Metal Detector are required.

Bunting Metal Separation System Recapture Plastics-0424In plastic recycling plants, Free Fall Metal Detectors such as the quickTRON 03R not only detect but also reject metal contamination.   Gravity free-fall style metal separators are specifically designed to isolate and separate any contaminated material moving in the product flow.  They automatically detect, pick up and reject both ferrous and non-ferrous from the product flow without any interruption to the line process.

As each application can be unique, selecting the optimum Metal Detector for an application is best achieved by conducting a site visit to understand the process and the objective.

Bunting Magnetics is one of the world’s leading suppliers of Magnetic Separators and Metal Detectors which includes the Master Magnets and Metal Detection branded range of equipment.

RWM Becomes Metal Separation Test Centre

Interactive Stand 5Q11 at RWM

Visitor interaction is the theme of the Bunting stand at this year’s RWM (12-13 September, 2018, NEC, Birmingham, UK).  With their stand (5Q11) in prime-position opposite the entrance to the show, Bunting will invite visitors to take a lump of non-ferrous metal or stainless steel, place it on the belt of the metal separator, and witness separation.

Bunting Magnetics Europe at RWM16
The separation of stainless steel on a magnetic separator

“We wanted to do something different this year,” explained Dave Hills, Bunting’s Head of Sales.  “Visitor interaction is so important and we want people to handle the metal and then see what happens when they place it on the belt of the metal separation system.”

Operating on the stand at RWM will be a production-sized Eddy Current Separator and Stainless Steel Magnetic Separator, and demonstration-sized model of the popular Permanent Overband Magnet.

On the Stainless Steel Magnetic Separator, visitors will be able to separate several different materials.  These include large lumps of fragmented stainless steel, from secondary metal recycling plants, and printed circuit boards (PCBs) from electronic recycling operations.

The Stainless Steel Magnetic Separator uses a patented high strength magnetic roll that generates enough attractive power to separate even the weakest magnetic materials.  When passing through a shredder, the edges of stainless steel become weakly magnetic and this enables the effective separation.  Also, PCBs have small components that are weakly magnetic and these are attracted by the strong magnetic field and separated from non-magnetic materials.

Dave Hills will be speaking about the Stainless Steel Magnetic Separator in the Alternative Fuels Theatre on Wednesday 12th (12:30-13:00) and Thursday 13th (11:45-12:15).

Eddy Current Separators are a common feature at the RWM exhibition.  The Master Magnets design focuses on maximising non-ferrous metal separation whilst maintaining product purity levels.  The ability to produce the optimum separation of non-ferrous metals is dictated by the design of the high speed rotating magnetic rotor and visitors will be able to place non-ferrous metals on the separator and witness the dramatic and violent separation.

Bunting Master Magnets at RWM17
Non ferrous metals being separated on the Eddy Current Separator

As the Permanent Overband Magnet is one of the most commonly used magnetic separators in the recycling and waste industry, it was important to have a model on show.  Hundreds of Permanent Overband Magnets are built at the Redditch manufacturing facility each year and they can be seen on many pre-sorted refuse operations recovering steel cans and mobile plant such as crushers and screens.

“Participating in a demonstration is different to simply watching,” explained Hills.  “Visitors to the stand can choose the item they want to separate and then see what happens on the metal separator.”

Magnetic Separators Remove Contamination from Plastic Waste

EcoVyn Ltd has installed two Bunting Drawer Filter Magnets to remove ferrous metal contamination from plastic waste.  Since the installation of the magnetic separators, EcoVyn has reduced their waste by 94%.

EcoVyn Ltd is at the forefront of PVC compounding and brings pioneering new technology to the market place.  They offer one of the most advanced and innovative production processes in the UK producing reprocessed, blended and virgin compounds for a variety of applications.

EcoVyn first met Bunting at the Interplas international plastics exhibition in September 2017.  The company use a high proportion of plastic waste, of which 80% is post-consumer.  Presently, EcoVyn processes 1000 tonnes per month of good quality reclaimed plastic waste, which they plan to increase to 16,000 tonnes per annum.  The cleansed plastic waste is blended into virgin material, resulting in a 90% output of grade A product.  Waste generated during the manufacturing process is also recycled leaving less than 1% being discarded.

However, plastic waste is often highly contaminated with metal.  Metal Detectors were already installed to remove the metal contamination, but the reject rate was very high with over 60 tonnes of waste being generated, of which a high proportion was good quality plastic.

At Interplas, EcoVyn explained the problem to the Bunting team who agreed to conduct a site review.  During the review it was concluded that easily removable magnetically-susceptible metal could be removed, leaving the metal detectors to detect and separate non-ferrous metals.  This would then significantly reduce the number of metal detector rejections and, therefore, the amount of waste generated.

After a review of the process, Drawer Filter Magnets were recommended to be installed between the screw conveyor transporting the 8-10mm sized infeed material and the metal detector.  The metal-cleansed material would then pass onto a pulveriser before continuing through the process.

The Bunting Drawer Filter Magnet is used widely in the plastics industry and enables the simple and effective removal of ferrous metal from free-flowing materials.  The Drawer Filters installed at EcoVyn have two rows of high strength Rare Earth Neodymium Magnets.  The top row has two Tube Magnets with three in the second row aligned to sit below the gap in the top row.  This ensures that all the product strikes at least one of the Tube Magnets, where ferrous metal is attracted by the strong magnetic field and captured.

After the installation of Drawer Filter Magnets, the amount of waste was reduced from 60 tonnes to 4 tonnes.

Since installing the Drawer Filter Magnets, EcoVyn has established that a 20 minutes cleaning frequency is required, highlighting the high level of metal contamination commonly found in plastic waste.  The ferrous metal found captured on the Tube Magnets ranges from small fine ferrous dust to nails, washers, steel sheet shards and electrical capacitors.

Following the installation of the Bunting Drawer Filter Magnets, controlled laboratory tests have been conducted at Bunting’s Master Magnets facility in Birmingham which indicated that 99.9% of all ferrous metals had been removed.

The final plastic product produced by EcoVyn is then used to manufacture products such as pipe, internal windows, beading, picture frames, and shoe soles.
