3 UK Waste and Recycling Facts

Environmental Facts and Figures For The UK

Next week is RWM, the UK’s largest waste and recycling exhibition, and we thought that it would be interesting to look at some of the present industry facts and figures.

Fact 1 – How Much Waste Do We Generate?

Even though we are in 2017, the latest waste statistics in the UK relate back to data from 2015.  The DEFRA report stated that households generated 26.7 million tonnes of waste in 2015, a fall of 1.1% on 2010.  This equates to 407 kg per person in 2015 compared with 421 kg per person in 2010.

There was also a fall in the generation of Industrial and Commercial Waste between 2010 and 2015.  In 2015, 13.9 million tonnes of Industrial Waste was produced compared with 12.6 million tonnes in 2010.  The fall in Commercial Waste was greater, with 15.1 million tonnes in 2015, down from 20 million tonnes in 2010.

Fact 2 – Recycling Rates

The household waste recycling target agreed by the UK Government and the European union is 50% by 2020.  So how are the individual UK nations performing so far?

Fact 3 – Metal Packaging Recycling

The last figures from 2014 show that the total amount of metal packaging waste produced was 736,000 tonnes.  Of this, 428,000 tonnes (58.2%) was recovered and recycled, often using Magnetic Separation technology in the form of Overband Magnets and Eddy Current Separators.  In March 2017, the UK Government set a new target of 69% recycling rate for metal packaging by 2020.

The facts and figures indicate that changes are needed in the waste and recycling strategy to meet the revised targets.  At RWM it will be interesting to see and meet the companies who are involved in the recycling process, either undertaking the processing of waste or developing equipment to improve recycling techniques.

Can UK Metal Packaging Recycling Increase by 10% by 2020?

Are Revised Beverage Can Recycling Targets Realistic?

Every year, consumers in the UK use approximately 14 billion steel and aluminium beverage cans.  Of these, approximately 59% are presently recycled.  In the March 2017 budget, the Chancellor, Philip Hammond, announced new targets for 2020, with the metal packaging recycling rate rising to 69%.  We investigate whether this 10% rise is really achievable?

Present Beverage Can Recycling Figures

Bunting Vulcanis-1097Since the late 1980’s, there has been a huge change in the global attitude to waste and recycling highlighted by the fact that, in 1989, the UK’s beverage can recycling rate was just 2%.  Globally, the beverage can is regarded as being the most recyclable packaging for drinks.

By the end of 2017, the UK will be recycling 55% of all aluminium packaging and 76% of steel.  This is part of the 72.7% of all packaging used in the UK that will be recycled.

Using reported recycling rates for aluminium and steel beverage cans, it is estimated that 14.1 billion cans are produced each year, of which nearly 80% are aluminium.  Of the 14.1 billion, 5.8 billion end up in landfill.  It is believed that if all aluminium and steel cans were recycled in the UK, the number of green bins could be reduced by 17.5 million.

The reasons for need to recycle and reduce waste are mainly 3-fold:

  1. Reducing the amount of waste going to landfill;
  2. Reducing the amount of energy used to produce steel and aluminium (recycled aluminium uses 95% of the energy needed for virgin production and steel 75%);
  3. More efficiently using the planet’s dwindling resources;

How Can The New Targets Be Achieved?

Between 2014 and 2017, aluminium can recycling rates have increased by 9% (from 46% to 55%) and steel by 3% (from 73% to 76%).  As recycling rates reach higher levels, previous statistical trends show that the recycling rate growth slows.  The latest recycling targets (2020) are for a further 9% increase (to 64%) in aluminium and a 9% (to 85%) increase in steel.

Additionally, although these may be less relevant due to Brexit, in December 2015 the European Commission proposed targets of 65% of all packaging by 2025 and 75% by 2030.  Of this, the recycling targets for aluminium and steel were the same at 75% in 2025 and 85% in 2030.

These are significant increases in the recycling rates.  From trends over recent years, it is apparent that without significant changes in the way the UK recovers, handles, and recycles materials, the targets set by the UK government and those proposed by Europe will prove difficult to achieve.

Presently, there are several ways in which beverage cans are recovered including:

  1. Charity collection schemes, which commonly only collect aluminium due to the low prices for recovered steel cans.  These only account for a small percentage of all cans recycled;
  2. At designated can banks, where the only subsequent processing is separating steel from aluminium using a Magnetic Separator.  Again, this is a small percentage;
  3. From pre-sorted refuse, where households have segregated ‘recyclable’ waste into separate containers for processing in a Waste Sorting Plant.  This is a more automated system, with steel cans being commonly recovered off a conveyor by an Overband Magnet and aluminium cans either being manually picked or automatically separated using an Eddy Current Separator;Master Magnets Overband Magnet 2
  4. Automatically recovered from mixed waste, using Magnetic Separators and Eddy Current Separators.  The source of the mixed waste includes:
    • Cans incorrectly put in the mixed recyclable rubbish for waste collection by households;
    • Waste collection from city centres;
    • Industrial waste collection;
    • Other waste sources

The challenge for the UK Government is identifying where improvements in can recovery can be made.  Further automation and less reliance on the general public may be required.

The Future

There has been a government focus on recycling and waste reduction since the mid-1990s.  In over 20 years, the aluminium recycling rate was only just exceeded 50%.  The latest recycling targets ask for another 10% growth in just 3 years.Bunting Vulcanis-1098.jpg

Also, given the present infrastructure of waste handling and recycling in the UK, achieving a recycling rate of 85% for any material will be difficult.  Steel Cans have always been a primary recyclable product, but what changes are needed to boost the present rate of 76% up by a further 9% in 3 years when it has only grown by 3% since 2014?

Setting recycling targets is simple, but achieving them without a solid structured plan will be challenging.

Getting Metal Out of Plastic on the Bunting Stand at Interplas 2017

Bunting Magnetics Magnetic Separators and Metal Detectors at UK Plastics Show

The latest Magnetic Separation and Metal Detection technology will be on display on the Bunting Magnetics Europe stand (Hall 4, Stand H11) at Interplas 2017 (NEC, Birmingham, UK, 26th – 28th September 2017).

Bunting FFS Magnet-0064A
Bunting FF Drawer Grate Magnet

Bunting Magnetics is one of the world’s leading suppliers of Magnetic Separators and Metal Detectors.  The European manufacturing headquarters are based in Berkhamsted in Hertfordshire, UK and they have an extensive overseas network of distributors and marketing agents.  In January 2017, the company acquired Master Magnets, significantly expanding their range of Magnetic Separators and Metal Detectors.

“Interplas is the number one exhibition for the plastics sector in the UK,” said Dave Hills, Bunting’s Head of Sales, “and the show gives us a great opportunity to meet many existing and potentially new customers.”

Bunting Magnetics has a strong global relationship with the plastics sector.  Many of their Magnetic Separators have been designed specifically for use in the manufacture and recycling of plastics and plastic products.

The Magnetic Separators and Metal Detectors on the Bunting stand at Interplas are designed to capture, identify and remove metal contamination.  The presence of rogue metal damages processing equipment and affects the end-product quality and reject rates.

Bunting BPI-6151

The FF Drawer Grate Magnet is specifically designed for removing magnetically-susceptible particles from plastic.  The standard model has 2 banks of Neodymium Rare Earth Tube Magnets mounted inside a sealed housing.  Other variations are available including a low profile design for positioning underneath large hoppers and silos. Magnetic Separators with Neodymium Rare Earth Magnets remove even the smallest magnetically-susceptible particles.  On the stand will be examples of extremely strong Magnetic Grates, Plate Magnets, Tube Magnets, and the industry-standard FF Drawer Grate Magnet.  Visitors will be invited to test the magnetic strength for themselves.

Bunting Magnetics Europe at RWM16“This combination [FF Drawer Grate Magnet and the quickTRON Metal Detector] offers the best method of removing metal from free-falling materials,” explained Dave Hills.  “The Magnetic Separator captures and holds any magnetically attracted metals such as steel screws, bolts, steel slithers from worn equipment, and even work-hardened stainless steel.  This always proves to be the bulk of the metal contamination.For a complete metal separation solution, the FF Drawer Grate Magnet is fitted above a quickTRON Metal Detector.  The Metal Detector then identifies and rejects any non-ferrous metals.

“Any remaining metal will be identified as it passes through the Metal Detector and then ejected.  The cleansed plastic can then proceed safety into the next stage of the process, whether than is to the extruder or granulator.”

A working, production-sized model of the combined FF Drawer Grate Magnet and quickTRON Metal Detector will be on the Bunting stand at Interplas.  Regular demonstrations will enable visitors to witness the capabilities of the complete metal separation system.

pTRON Metal Detector

A range of pTRON Metal Detectors designed for use in Pneumatic transportation lines will also be on display on the Bunting stand.

With the acquisition of Master Magnets, Bunting also has an extensive range of Magnetic Separators and Eddy Current Separators for the recycling sector.

“The combined experience of Bunting and Master Magnets means that we have a solution for most metal separation problems.  The Master Magnets Eddy Current Separator is an industry standard and is used to remove non-ferrous metals from plastics in recycling operations across the world,” said Dave Hills.

Quality and Environmental Accreditation for Bunting Magnetics Europe

Bunting Successfully Transition to ISO9001 2015 Quality and ISO14001 2015 Environmental Standards

Bunting Magnetics Europe has successfully transitioned to the new ISO9001:2015 Quality and ISO 14001 :2015 Environment Standards.  The certification covers the manufacture and supply of Magnetic Separators, Metal Detectors, and Magnets and Magnetic Assemblies from their European manufacturing headquarters in Berkhamsted, UK.

Denis_Elkins_Bunting_Magnetics_Europe-2171

Denis Elkins, Bunting Magnetics Europe’s Quality Assurance Manager, explained the importance of transitioning to the ISO9001:2015 Quality standard.

“Bunting has held the ISO9001 quality standard since May 2005.  The quality of our products, manufacturing processes, and business management is of utmost importance to us and our customers, and, we believe, is one of the primary reasons for our continued success.”

The ISO 9001:2015 Quality Standard was revised in 2015 and now has a definitive focus on business performance.  The process approach has been combined with risk-based thinking, promoting the Plan-Do-Check-Act cycle at all levels in the organization.  The new standard acknowledges that modern organisations will have several management standards in place, and the 2015 version has been designed to be easily integrated with other management systems.  The new version also provides a solid base for sector-quality standards (automotive, aerospace, medical industries, etc.), and takes into account the needs of regulators.

Bunting also recognises the importance of adopting good working practices in accordance with international Environmental Standards and originally attained the ISO14001 standard in February 2002.  The ISO14001:2015 Environmental Standard sets out the criteria for a certifiable environmental management system.  It maps out a framework that a company or organization can follow to set up an effective environmental management system, regardless of its activity or sector.

“We have been actively involved in the environmental sector supplying metal recycling equipment for many years,” explained Denis, “and so maintaining this environment standard was simply common-sense.  As a UK manufacturing company we recognise that we have a responsibility to protect the environment and the standard provides the framework to implement, measure and manage the most effective methods of operation to reduce waste and pollution.”

Export Success at FIP Solution Plastique Exhibition

Bunting Magnetics Support BMS France at Plastics Show in France

Dave Hills, Bunting Europe’s Head of Sales, was on the stand of local distributor, BMS France for the duration of the major annual international plastics exhibition, FIP Solution Plastique, held in Lyon, France between 13th and 16th June 2017.  Dave gave us this report:

“Last week [13th to 16th June] it was hot and humid in Lyon.  And it was debatable whether the air conditioning in the exhibition centre was actually working.  However, the turnout for the show was fantastic.

FIP Solution Plastique is the number 1 show for the plastics sector in France.  There was a technically and globally diverse group of exhibitors present, all specialising in working in the plastics industry.

We were present to support our local distributor BMS France.  Being on the stand gave me the opportunity to develop relationships with the BMS team, deliver some product training, and also learn about the plastics market in France.  I also had the opportunity to meet the BMS Spain team, based in Barcelona.

It was also good to meet and talk with other equipment suppliers, many of who had equipment on display at the show.  It was interesting to hear their feedback on present market conditions.  We find exports visits such as this invaluable.

Bunting_FIP_Solution_Plastique_France-1987

Along with our Metal Detectors and Magnetic Separators, BMS had a wide range of equipment on the stand.  There were 3 operating Boy Injection Moulding Machines on one stand and a Woojin Injection Moulding Machine on a 2nd stand.

There were also 5 Wanner Granulators, and Pixargus had a live demonstration of their unique surface inspection and dimension measurement system.

The extensive range of products and the interactive nature of the BMS France stand made it one of the busiest at the show.

Bunting_FIP_Solutions_Plastique_17-1985

It was interesting to think that all of the aforementioned equipment relies on the plastic pellets and raw materials being metal-free.  And getting metal out of plastic is our speciality.

BMS France was able to talk to visitors about a complete solution, with demonstrations of the quickTRON 03R Metal Detector and FF Drawer Filter Magnet removing both ferrous and non-ferrous metals.

Being in France also gave me an opportunity to hear people’s thoughts about BREXIT.  Unlike some other European countries that I have visited since the referendum, people in France have a very negative opinion about the UK leaving the EU.  In fact, many people asked whether the decision could be overturned.  This just highlights the importance of a negotiated exit that involves free trade.

However, the atmosphere at the exhibition was very positive.  Indeed, BMS France sold 2 Injection Moulding Machines at the show, which was fantastic.  And both will be protected by Bunting Metal Detectors and Magnetic Separators.

An excellent show and we will be back in 2018.”

On the stand, BMS will be showcasing Bunting equipment including:

Quicktron Metal Detector

Gravity free-fall style metal separators are designed specifically to isolate and separate any contaminated material moving in the product flow.  Ferrous and non-ferrous metals are automatically detected and removed from the product flow, without any interruption in the production process.

FF Drawer Filter Magnets

FF Series Draw Magnets are perfectly suited for collecting and separating contaminant ferrous metal from gravity fed, dry, free flowing materials.  Housed inside are the extremely strong Neodymium Rare Earth Magnets which capture and hold small pieces of ferrous metal contaminant.  Made specifically for the plastics industry, this is the only available drawer magnet design that features temperature-compensated rare earth magnets.Bunting_FIP_Solutions_Plastique_17-1985

Grate Magnets

Grate Magnets or Magnetic Grates are manufactured with a 25mm Tube Magnet from high quality 304 Stainless Steel, with 316 Stainless Steel as an option for high corrosive applications.  They are available for Square or Round Openings and with optional baffles.  Standard sizes range from 100mm to 1000mm.  These Grate Magnets can be placed in hoppers or feed pipes to collect ferrous metals and are ideally suited when they can be easily removed for cleaning.

“As a leading supplier to the plastics industry, it is important that we are here at FIP.  It gives us the opportunity to meet and talk to plastic producers about metal contamination issues,” said Dave.

Positive Vibes For Recycling at Waste 17

High Interest in Magnetic Separators and Eddy Current Separators at Waste 17

Despite the rain and the General Election, Waste 17 proved to be a great success on 8th June 2017.  The Waste 17 exhibition was held at Manchester United’s ‘Theatre of Dreams’, their Old Trafford football ground, with both indoor and outdoor exhibits.

“We were really excited [about Waste 17] as this was the first time that Bunting Magnetics and Master Magnets had exhibited together since the announcement of the acquisition in January [2017],” said Bunting Managing Director, Simon Ayling.

Bunting and Master Magnets were headline sponsors of the only Northern-located recycling and waste exhibition, organised by the team at Skip Hire Magazine.  The exhibition was well attended by both exhibitors and visitors.  In the external area, there was a wide range of large mobile recycling plant, waste collection skips, and vehicles.  Companies in the indoor exhibition were providing both services and equipment to the waste and recycling sector.  There was also a seminar area.Waste_17-0634

The Bunting/Master Magnets stand was located directly in front of the main entrance doors and on display was an operating Eddy Current Separator, Permanent Overband Magnet, and Metal Detector.  On the Eddy Current Separator, small non-ferrous metal was being separated from shredded plastic.

“This year we wanted to show visitors our equipment,” explained Simon.  “Having a working Eddy Current Separator on the stand is always impressive and we were able demonstrate the separation capabilities.  There was a really positive reaction from the visitors’ and we are sure that undertaking demonstrations was an important factor in the high number of enquiries.”

The team were also able to demonstrate the depth of field of the Permanent Overband Magnet, used to separate ferrous metals from conveyed non-magnetic material as found in MRFs and Sorting Stations.Waste_17-0813

“The joining of Bunting and Master Magnets has been tremendously successful.  Being together at Waste 17 gave us a chance to meet and talk with existing and new customers and show that our ability to provide a complete metal separation solution has been enhanced.  We are now looking forward to our next joint exhibition, RWM17.”

Getting Metal Out of Processed Vegetables

Ideal Locations for Magnetic Separators and Metal Detectors in a Vegetable Processing Plant

Processed vegetables are a vital part of the food chain.  Tens of thousands of bags of pre-cut carrots and freshly prepared kale are bought in supermarkets daily.  Frozen vegetables have been very popular since Clarence Birdseye invented the quick freezing method in 1924.  Also,  often-unnoticed processed vegetables are present in many everyday food items such as tinned soup, baby food, sauces, and ready-made meals.

However, processing vegetables takes a great deal of care and attention as the products are often delicate and can be easily damaged.

BUNT-2286 4 8.5x11 plants

As with all processed foods, there is always the risk of metal contamination.  Metal can be introduced at various stages in the process.  The design and positioning of the Magnetic Separator or Metal Detector has to also respect the delicate nature of the product.

Untreated Vegetables Feedstock

During the collection and transportation of the raw vegetables, there is always a high risk of metal contamination.  This can be remove using a Plate Magnet.  To avoid contact with the vegetables and eliminate the risk of damage, the Plate Magnet is suspended above the incline conveyor feeding the washer.  Metal is attracted up onto the face of the Magnet and held until cleaned.  This is ideal to remove larger metal items such as screws and nails.

Post Washing

The vegetables washing process frees dirt and other detritus including metal particles.  Prior to the washed vegetables being fed into a drier, a Permanent Magnetic Pulley, replacing the standard head pulley of a conveyor, attracts and automatically removes any free metal before entering the drier.  Again, there is no physical content between the Magnetic Separator and the vegetables.  After drying, the vegetables are fed into a dicing machine.

Prior to Dicing

Plate Magnet Tapered Step-9545
Plate Magnet Tapered Step

The blades on a dicing machine are delicate and expensive.  Metal contamination can cause significant damage.  To ensure that no metal is present, the dried vegetables are fed over the surface of a Plate Magnet.  This enables higher levels of separation that when the Plate Magnet is suspended as the material is passing closer to the area of maximum magnetic strength.  Any potential damage to the vegetables as they flow over the surface of the Plate Magnet is limited.  Metal is captured and then held under the lip of a tapered step on the surface of the Magnet.

Undersized Vegetables

Smaller sized diced vegetables are often taken on a different route.  They can be mixed with water, for ease of transportation, before being reintroduced into the process.  Immediately after dicing, the smaller particles fall through a Quicktron Metal Detector to remove any small ferrous and non-ferrous metals (including any broken blades from the dicer).  Water from the external source is passed through a Magnetic Liquid Filter Magnet to ensure that any rust or other ferrous metal contamination is not introduced into the process.  The Undersized Vegetables are mixed with the water and then re-introduced into the process.

Final Packed Product

Metron 05C Metal Detector
Metron Metal Detector

The final stage of weighing and packing includes 3 steps of Metal Removal and Detection.  Prior to weighing, the processed vegetables are passed over the surface of a Plate Magnet to ensure that all ferrous metal contamination has been removed.  After weighing, the vegetables fall under gravity through a Quicktron Metal Detector where any non-ferrous metals are removed.  Finally, after packing, the finished packed batch of processed vegetables are passed through a tunnel-type Metron C02 Metal Detector as a final check prior to shipment.

This is a typical example of a Vegetable Processing Plant.  However, each plant is unique and often a site visit is required to assess and recommend the best ways to ensure a metal-free end product.

Temperature Effect on Rare Earth Magnetic Separators

Neodymium Magnet Damage From High Temperatures

If a Neodymium Rare Earth Tube Magnet is put into a red-hot fire, then it would not be surprising if the magnetic properties are destroyed.  However, what if the same Tube Magnet is just exposed to steam being flushed through a pipeline system to clean the pipes?

Tube Magnets manufactured with high quality Neodymium Magnets are able to operate well in temperatures up to 100 degrees C.  There is a gradual drop in magnetic strength when the temperature rises above 80 degrees C, but this loss in magnetic strength recovers when the temperature falls back to normal levels.

However, as soon as the Neodymium Rare Earth Tube Magnets are exposed to temperatures exceeding 100 degrees C, the magnetic strength becomes compromised.  On returning to normal operating temperatures below 80 degrees C, there is an irreversible loss in magnetic strength and permanent damage.

Bunting Magnetic Liquid TrapIn a pipeline which is cleaned using steam, the temperature will be above 100 degrees C for a period of time.  This will certainly damage any standard Neodymium Rare Earth Tube Magnets or Magnetic Separators (e.g. the Magnetic Liquid Filter) installed in the pipeline.  However, most users are totally unaware of the potential loss in magnetic separation performance and that the ability of the Magnetic Separator to remove small pieces of metal contamination has been permanently compromised.

Magnetic Separators in High Temperature Environments

There are types of Neodymium Rare Earth Magnets that are designed to operate in high temperature environments.  These tend to be lower in magnetic strength at room temperature, but the magnetic field does not degrade as quickly as standard Neodymium Magnets at higher temperatures.  Also, on returning to normal temperatures, there is only a small irreversible loss in magnetic field, which is only experienced when first exposed to high temperatures.

This type of high temperature Neodymium Rare Earth Magnet should be used in pipelines which are being cleaned for prolonged periods with steam.

Tube_Magnet_FireFor applications where there are extreme high temperatures (exceeding 150 degrees C), then the best option is to use Samarium Cobalt Rare Earth Magnets (SmCo).  These retain their magnetic properties in temperatures up to 300 degrees C.  However, such applications are rare.

It is recommended that the magnetic properties and strength of any Magnetic Separator installed in a pipeline cleaned with steam or in an environment where there is constant exposure to high temperatures is checked on a regular basis (e.g. during an annual Magnetic Separation Audit).  The best way to do this is with a Magnetic Pull Test Kit.

HFS Drawer Magnet Removes Metal from Recycled Plastics

French Plastics Recycling Operation Installs Bunting Drawer Magnet

The latest HS Drawer Magnet has just been boxed ready for despatch to a Plastics Recycling company in France.  The Magnetic Separator was manufactured in the Bunting Magnetics European manufacturing facility in Berkhamsted, UK.

HSF_Drawer_Grate_Bunting-1864

The French Plastics Recycling operation will install the HS Drawer Magnet to capture and remove ferrous metal contamination from the reclaimed plastic.

HFS Drawer Magnets are commonly used in virgin and secondary plastic processing operations.  The Magnetic Separator is equipped with powerful Neodymium Rare Earth Tube Magnets which enable the capture of both very fine iron and also work-hardened Stainless Steel.

How the HFS Drawer Magnet Works

In operation, material falls under gravity into the opening of the HFS Drawer Magnet.  Inside the housing are two rows of Tube Magnets, staggered to ensure that all the product has to pass over the surface of a magnet.  The magnetically susceptible particles are attracted and held onto the surface of the Tube Magnet, whilst non-magnetic material passes through.

Bunting Grate Magnet

The HFS design of Drawer Magnet enables easy-cleaning of the Tube Magnets.  Unlike other designs of Easy-Clean Grate Magnet, the Tube Magnets are not positioned within an outer tube and are in direct contact with the product.  This ensures maximum magnetic particle capture.

When the Tube Magnets need to be cleaned (daily cleaning is a recommended minimum requirement), the extended Tube Magnets are manually pulled outside the housing using an external handle.  Any captured magnetic material is stopped from being pulled outside the housing by specially designed Grommets.  These Grommets are positioned in the side of the housing and fitted tightly around each Tube Magnet.  Each Tube Magnet has a non-magnetic tapered end which, on reaching the Grommet, allows the captured metal contamination to fall into a separate collection bin.  The Tube Magnets are then fully cleaned and ready to be re-introduced into the product stream.

Typical Features of the HFS Drawer Magnet

  • For Gravity Flow Applications in All Industries;
  • Configurable design to suit the flow of materials and separation required;
  • High duty construction, for long life;
  • Large range of sizes, magnet types and finishes available;
  • Easily fitted into existing systems, optional  top and bottom transitions available;
