Plastics Positivity at Technivation

Polymer Training and Innovation Centre Hosts UK Plastics Sector Professionals

The Technivation conference, hosted by the Polymer Training and Innovation Centre in Telford (18th April 2018), attracted delegates from across the UK plastics sector.

The Polymer Training and Innovation Centre (PITC) provides training for engineers working with plastics and has an extensive range of working equipment including moulding machines, pneumatic conveying systems, and magnetic separators.

Bunting Europe at TechnivationAt Technivation, there were talks from machinery manufacturers and also an industry update from the British Plastics Federation.  BPF Membership Services Director, Stephen Hunt, highlighted a change in the awareness and public perception of plastics since the airing of the BBC Blue Planet II series at the end of 2017.  The BPF have been working hard to clarify misconceptions about plastics, highlighting that plastic is vital in the manufacture of so many products including cars, medical equipment, and IT.  They are presently working closely with the UK Government on the proposed tax for single use plastics, which closes on 18th May 2018.

As Stephen Hunt explained, the plastics sector is the 8th largest exporting industry in the UK with a turnover of £25.5 billion.  The sector is also the 2nd largest employer in the manufacturing industry.  He also highlighted how waste from the USA and European Union combined only contributes 2% to the amount of plastic waste found in our oceans.

Delegates at Technivation had the opportunity to tour the training facility and meet representatives from equipment manufacturers including Summit Systems, Kistler, Arburg, and Staubli.  Tom Higginbottom, Bunting’s Sales Engineer, was demonstrating how to effectively remove metal from the plastics process using a combination of a FF Drawer Filter Magnet and Quicktron Metal Detector.

“At Technivation it was really good to be able to demonstrate how to remove metal and also to show how the equipment is actually installed on a working moulding machine,” explained Tom.  “We supplied the FF Drawer Filter Magnets to PTIC so that the importance of metal removal is included in the training programmes.”

6 Metal in Food Safety Scares in 2017

UK Food Standards Agency Reports 6 Metal-in-Food Problems in 2017

Six warnings of UK food being contaminated with metal fragments were reported by the UK Food Standards Agency in 2017.  The food safety warnings ranged from sweets to meat products.

Metal In Food Safety Warnings 2017

Greencore recalled various brands of Chicken and Bacon Caesar Wraps because of concerns that the products contained metal fragments (20 December 2017).  Greencore, as precautionary measure, recalled various brands of Chicken and Bacon Caesar Wraps.  The products, manufactured by Greencore, were sold in Aldi, Co-op Food and Morrisons retail stores.

Athole Tablet Ltd recalled tablet products because of possible contamination by small pieces of metal (31 August 2017).

William Santus & Co recalled Uncle Joe’s Liquorice & Aniseed Extra Strong Mints (35g tins) as there were concerns that the sweets may have contained small pieces of metal (15 May 2017).

Morrisons recalled Trimmed Beans because of the reported presence of small pieces of metal (20 April 2017).

Metal Found In Morrisons Green Beans

Quorn Foods Ltd recalled a batch of its frozen Quorn Meat Free Mince because of the presence of small pieces of metal (2 March 2017).  The affected product was only on sale at Tesco from 27 February 2017 to 1 March 2017.

Lotus Bakeries UK Ltd recalled Lotus Biscoff Crunchy Biscuit Spread because of small metal contamination concerns (2 March 2017).  This product was sold at Tesco, Sainsbury’s, Morrisons, Asda, Waitrose, Ocado and Nisa stores.  In addition, batch number 7005109 with ‘best before’ date 5 February 2018 has also been sold through East End Foods.

How Does Metal Get Into Food?

Metal In Food-1136All of the foods listed have been processed and it is during that process that metal can contaminate the product.  Food entering a process plant will potentially go through stages of washing, size reduction (e.g. cutting, mashing, slicing), mixing, forming, cooking and packaging.  Metal can be introduced from the wear or failure of processing equipment, or through human error.  In fact, it is not uncommon for metal to contaminate food.  However, it is unusual that metal contaminated food reaches the end consumer.

All food companies use a combination of Magnetic Separators and Metal Detectors to separate and detect the metal.  When metal contaminated products are found to reach the consumer, it can be concluded that this safety equipment failed.

Reviewing the performance of the Magnetic Separators and Metal Detectors on a regular basis is important to ensure that any metal contamination problem is identified and dealt with at the factory.  Regular audits will check the integrity of the Magnetic Separators, assessing and recording the magnetic strength and reassessing the location.  Audits for Metal Detectors will check the application, assessing detection sensitivities.

Often such audits find that changes in the process or product (including packaging) mean that the performance of the Magnetic Separators and Metal Detectors is no longer optimised.

Thankfully, metal in food safety alerts remain relatively infrequent in the UK, although each one causes significant financial and reputation damage to the producer and food retailer.

New UK Drinks Container Recycling Strategy Creates ‘Bottleneck’

UK Waste Plan Means More Recycling Plants

The UK Government’s announcement that people in England will soon have to pay a deposit when they buy drinks bottles and metal cans [28th March 2018] in an attempt to curb waste is expected to create a ‘bottleneck’ in the recycling chain.  Scotland has previously announced plans for a deposit return scheme and Wales has launched a study to consider it.

drinking-water-filter-singapore-1235578_960_720Other countries, including Sweden and Germany, already operate schemes where people pay a deposit when purchasing some drinking containers.

This latest announcement may be considered as a knee-jerk reaction to the global dismay about plastic waste following the airing of the Blue Planet II series.   Environment Secretary Michael Gove said there was no doubt that plastic was “wreaking havoc” on the marine environment and discarded plastic bottles and cans “end up dumped on pavements and lobbed into rivers, lakes and the sea”.

Although most people agree with the sentiment of the new policy, there are serious concerns about the UK’s ability to handle the increase in the amount of plastic waste.  The UK Government has not outlined how the recovered plastics will be recycled and how it will work financially.

Already, since China banned plastic waste imports [January 2018] there have been concerns about how the UK will manage plastic waste, especially as 2.7 million tonnes was shipped to China since 2012.  This new policy will potentially reduce the amount of plastic going to landfill, but also add to the amount of plastic waste that was previously shipped to China.  That equates to a lot of plastic waste.

Are There Enough Plastic Recycling Plants?

An increase in recovered plastic waste means that there needs to be a significant growth in the number of specialist recycling plants.  However, profitably operating a plastics recycling plant has proven to be difficult, with many plants being commissioned and then closed or sold within a very short space of time.

There has been an established network for the collection and successful recycling of steel and aluminium beverage cans for decades.  Part of the reason for the success is that both materials are easily recyclable, using a combination of Magnetic Separators and Eddy Current Separators, and converted into new steel and aluminium.  Presently, the same cannot be said for plastic.

The UK Government may decide to commit all the collected deposits to expanding and funding a network of specialist recycling plants, although where this money will go is is presently unclear.  It will be interesting to hear if there are plans to invest in the development of technology to enable successfully and financially viable mixed plastic recycling.  Also, will product designers now be forced to consider the recyclability of a product rather than the aesthetic appearance?

Certainly, a holistic plan is needed before this new initiative is put in place.

Fish Cakes Contaminated with Metal

Youngs Seafood Recalls Metal and Plastic Contaminated Fish Cakes 

In February 2018, Young’s Seafood Ltd recalled its Chip Shop Fish Cakes 6 pack due to the possible presence of pieces of metal and plastic in some packs.  The presence of metal and plastic makes this product unsafe to eat and presents a safety risk. The affected product is sold in some Farmfoods and Heron Foods stores.

Youngs is a leading British producer and distributor of frozen, fresh, and chilled seafood, supplying approximately 40% of all the fish eaten in the United Kingdom every year.  However, this product recall damages their brand and customer confidence.

Where Does Metal Contamination Come From?

Metal contamination is commonly found in food processing plants.  It can be present in the food or ingredients delivered to the processing plant, or introduced during the production process.

Food producers use a combination of Magnetic Separators and Metal Detectors to ensure that the metal contamination is removed before the final packaged food is despatched to supermarkets and sales outlets.

So How Could This Latest Food Scare Happen?

Youngs is not the first or last major food producer to face a product recall due to metal contamination.  Most food producers have installed suitable Magnetic Separators and Metal Detectors.  However, often the contamination issue is a result of old equipment no longer adequate for the application, a failure of equipment, or a change in the process.

Magnetic Separators do not lose magnetic strength over time unless they are damaged or subjected to high temperatures.  However, it is important to annually check the magnetic strength and integrity of the Magnetic Separators.  This can be easily done using a Magnetic Pull Test Kit as part of a Magnetic Separator Audit.

Bunting Magnetics Pull Test Kit

The Magnetic Separator Audit also reviews changes in the production process and may propose the relocation of some equipment to ensure that maximum protection is maintained.

Metal Detectors are often used later in the process, once the product is made and after packaging.  The settings of the Metal Detector need to be regularly checked, especially if there are changes in the production process, product or packaging.  Also, settings on the Metal Detector may be accidentally altered, reducing the sensitivity and resulting in metal contamination being missed.  Again, an annual Metal Detector Audit will review the performance and settings and ensure that there is maximum protection.

Unfortunately, reports on metal contaminated food are not unusual.  Other examples include:

Is Recycling in UK Reaching Crisis Point?

Troubled Times for the UK and European Recycling Sectors

There appears to be a distinct disconnect between the political rhetoric and what is actually happening in the waste and recycling sector.  In the UK, Theresa May has pledged to eliminate plastic waste by 2042 and the European government has ‘declared war’ on plastic waste setting a target of having all packaging reusable or recyclable by 2030.

China WasteHowever, it has been reported [BBC News 1st March 2018] that waste recycling rates in the UK are falling for over 14 million households.  Also, China’s import restrictions on waste materials has put tremendous pressure on the recycling sector and it is anticipated that UK firms are likely to close [MRW].

The global problem of Plastic Waste has been at the top of the media agenda since the BBC’s Blue Plant II showed how it is contaminating our world and endangering our wildlife.  The noise from environmental activists and the general population has been deafening.

Surfer and Plastic WastePoliticians had to respond and announced targets for dealing with plastic waste.  However, the announcements do not include details about how these tough targets are going to be met.

In the UK, we presently recycle 29% of our plastic, although this figure is presently under debate [Industry ‘exaggerates plastics recycling success’ – BBC News 6th March 2018].  The target for 2020 is 57% and 0% by 2042.  The present recycling rate is low due to the complexity of the process and economics.  Magnetic SeparatorsEddy Current Separators and Metal Detectors remove metal and there is other technology to sort by colour and plastic type.  However, producing a useful plastic from waste that can be introduced as a raw material into primary plastic production (such as happens with aluminium and steel) is presently exceptionally difficult.  Contamination at the collection source, during transportation, and during process is one of many problems.  Until those issue are addressed, plastic waste will continue to pose a problem.

Bunting Overband Magnet over Conveyor 2

The solution has been shipping mixed waste materials to China and other countries for manual separation.  This is no longer an option, at least in China.

A cohesive plan of action is required, with the setting of realistic targets reflecting the technology and economics of waste recycling.  At present, it appears that politicians are just making statements to appease the masses.

Contamination Hinders Plastic Recycling

Metal Contamination is Another Problem Facing Plastic Recycling Companies

The environmental impact of poorly managing plastic waste has been in the headlines since the BBC’s Blue Planet II series was aired at the end of 2017.  In January, Theresa May made a pledge to eliminate the UK’s plastic waste by 2042, although the detail of the plan has yet to be unveiled.  Less than a week later and the EU ‘declared war on plastic waste’, announcing the intention to ensure that every piece of packaging on the continent is reusable or recyclable by 2030.

plastic-trash-in-oceans-and-waterways

Presently, there is an unprecedented negative feeling towards plastics.  However, plastic is and will continue to be one of the most versatile and useful materials available.  This versatility is down to the wide range of plastic types, as can be seen in any household.  Plastic is present in food packaging, mobile phone casings, tables, chairs, DVDs, televisions, and many other everyday items that would not exist unless made of plastic.

Certainly, product designers need to give recyclability a higher priority and this change in attitude is required for all materials and not just for plastics.  At present, plastic is the environmental villain.

Effectively managing plastic waste is not a new problem for the UK.  With the introduction of Material Reclamation Facilities (MRFs) in the 1990s, there was an abundance of segregated materials, including plastics, for which there was no end market.  These were stored or exported overseas, and there were reports of warehouses in Germany stocked full of unrecyclable waste materials.

This resulted in changes in the EU definition of ‘waste’ that prevented the easy movement of secondary materials within Europe, but this did not address the main problem.  The market for materials such as secondary plastics did not exist.  Advances have been made and there are products being made out of recycled waste plastics (e.g. furniture) and even plastic roads.

Technology has advanced, but the main problems remain.  Complex recycling plants are now able to separate different types of plastic by colour and type, but the process is not perfect.  To further complicate the problem, other non-related materials, such as metal and even building materials (e.g. concrete and bricks), contaminate the vast majority of waste plastic packaging.

Contaminated Pre-Sorted Waste

Most plastic packaging enters the recycling process as pre-sorted household waste.  The specification of what materials are mixed in a single recycling bag depends on the recycling strategy of the local council and varies considerably across the UK and Europe.

Recycled UK Bunting Magnetic Separators-3On arrival at a MRF, the collected materials are then separated into metal, plastic, cardboard, and any other materials defined within the local strategy.  Separation of these materials is achieved using either technology or, more commonly, a combination of separation equipment and human pickers.  This is a dirty, difficult, and unpopular environment in which to work.

The ability to successfully separate the materials is compromised by the presence of other waste.  These materials have been incorrectly added to recycling bags at the household or during collection and include used-nappies, food waste, paint tins, and other problematic materials.

At the MRF, metal packaging (e.g. steel and aluminium beverage and food cans) is commonly recovered using Overband Magnets positioned over the main feed conveyor prior to the picking line.  Other materials are manually handpicked and stored separately.  Up until recently, the mix of plastic packaging could then be sent to a specialist UK plastic recycling plant or overseas to countries such as China.

Contaminated Plastic Waste

Since 2012, British companies have shipped more than 2.7m tonnes of plastic scrap to mainland China and Hong Kong.  However, this only accounts for two-thirds of all the plastic waste exported from the UK.

Plastic waste sent to China is, where possible, commonly hand-sorted into individual plastic types (i.e. removing plastic tops by hand), with all other added contamination removed manually.  This involves a huge, low-paid workforce.  Similar manually based recycling operations in Europe would be prohibitively costly with unacceptable working conditions.

In December 2017, China announced that in early 2018 it will stop importing “foreign garbage” stating that such waste materials was commonly contaminated with “large amounts of dirty waste or even hazardous wastes”.

Specialist plastic packaging recycling plants in the UK have been under intense financial pressure for many years.  There have been calls for better legislation and Government support, but too many plastic recycling plants open and are then forced to close due to being financial unviable.

A typical plastic recycling operation needs a complex system of separation equipment.  The plant also needs to be able to adapt to huge variations in the nature of the delivered waste plastic.  There are also strict environmental regulations on storing and handling waste plastic.  Such plants are expensive to install and operate.

Hanbury Plastics Bunting Overband Magnet-1

Early in the process, ferrous and non-ferrous metal contamination is removed from the waste plastic using Magnetic Separators and Eddy Current Separators.  Initially, after the plastic is released from the compacted bale, the waste is fed into a primary shredder.  To protect the shredder from damage, an Overband Magnet is suspended across the feed conveyor and removes large ferrous metal.

At this stage, the type of ferrous metal contamination found in the plastic is diverse and often surprising.  It can include metal packaging miss-sorted at the MRF, heavy lumps of iron that increase the weight of the plastic bale, and metal picked up during transportation.  There have even been reports of car engine blocks.  Reasonably sized items of cast iron entering the shredder will cause significant and costly damage and result in the plant being closed until a repair is possible.

After the primary shredder, the waste plastic has been reduced in size and many contaminants liberated.  This shredded waste plastic is fed onto another Magnetic Separator, commonly a Drum Magnet or Pulley Magnet, to remove liberated smaller ferrous metals.

Metal Found in Plastic Recycling Bunting Magnetics-3The type of ferrous metal separated at this stage includes steel spanners, nuts, bolts, screws, fine metal wires, springs, iron shards, fine ferrous dust, and chunks of stainless steel.  Most of the ferrous metal was not part of the original plastic packaging and has been introduced between disposal and processing.

The cleansed plastic waste then passes over an Eddy Current Separator to remove non-ferrous metals.  Commonly separated metals include aluminium beverage cans, foils, tubes, and even window frames.

After the metal contamination has been removed, the plastic waste moves to the next stage in the plant, which could be further separation of contamination or sorting by colour or plastic type.

The high level of metal contamination highlights the challenges facing waste plastic processors.  It was one of many contaminants, not present in the original plastic packaging, that have to be removed.

Before UK and EU Government officials make recycling pledges to pacify environmentalists, they need to consider the practicalities and difficulties faced when processing waste plastic packaging.  Contamination will always be present, and is one of the reasons for exporting this difficult waste material overseas.  Reducing such contamination will make it easier to recycle waste plastic, but there is no clear strategy to achieve this goal at present.

42 In Line Magnets Ensure Baby Food Is Metal Free

Magnetic Separators Remove Metal During Baby Food Production

A Baby Food producer based in Germany has purchased a further 14 In Line Magnetic Separators to guarantee a metal-free product.  The latest 14 In Line Magnetic Separators are in additional to 28 already supplied and installed as they equip their food manufacturing plants across Europe.

Bunting Magnetics In Line Magnet-9528In Line Magnetic Separators are designed to easily fit into an existing pneumatic or gravity fed pipeline transporting food stuffs.  Both ends are fabricated to connect with the installed pipework.  The central body of the In Line Magnet has a strong Rare Earth Neodymium Plate Magnet.

A key feature of the In Line Magnetic Separator is that there is no restriction to the product flow.  In this particular project, baby food passes through the body of the In Line Magnet and any ferrous or weakly magnetic materials are attracted by the strong magnetic field and then held against the face or the Plate Magnet.

The Plate Magnet has a tapered step, which intensifies the magnetic force and also provides an area to collect rogue metal contamination.

As the Baby Food has chucks of vegetables and meat, it was important that there was no restriction to the product flow where the food could be damaged or blockages could occur.  The Magnetic Liquid Filter, which uses Rare Earth Neodymium Tube Magnets, would not have been suitable for this application.

Bunting Magnetics In Line Magnet-9552Periodically, the captured metal is cleaned off the face of the Plate Magnet.  Access is designed to be simple and quick, with the Plate Magnet swinging away from the body on hinges.

All 42 In Line Magnetic Separators are designed for use in pneumatic pipelines up to 15 psi.  They are manufactured from Stainless Steel there are a range of standard sizes available.
