PlasticsFuture 2023

At the end of June, I attended a fascinating conference held at the University of Portsmouth. PlasticsFuture 2023 was convened over three days and brought together speakers from across the world to present their research around, and experiences of, plastics pollution. The team behind the conference are part of Revolution Plastics, an interdisciplinary research group based at the University. The group is an initiative drawing together colleagues from across the University of Portsmouth and assembling teams of researchers, business-leaders, campaigners, and citizens who share their commitment and ambition to transform the way we make, use, and dispose of plastic and prevent pollution. From developing sustainable fashion, to combatting microplastics, they are putting their research into practice, and addressing plastics pollution; generating a globally-relevant community of plastics researchers and contributing to the sustainable transition of the city of Portsmouth as a prototype and showcase for a sustainable plastics future.

The three days were split into 6 sessions:

• Session 1: Microplastics - detection, transport and impacts for environmental and human health
• Session 2: Exploring the current issues of plastic use within the context of fashion and textiles and the role of plastics in the future
• Session 3: Plastic pollution in the Global South
• Session 4: The Plastics That Made Us
• Session 5: Creative Solutions to Global Challenges
• Session 6: Tackling plastic pollution: Global Change Perspectives

Session 1: Microplastics - detection, transport and impacts for environmental and human health

Description: Microplastics are everywhere in our lives, in the food we eat and the air we breathe. As research on microplastics gathers pace, it is becoming apparent that microplastics may impact human health and we need to understand how to limit our exposure.

There are currently many projects and policies looking at how to reduce plastic use in packaging but less understanding on how this will impact microplastic numbers. This session will take a closer look at the challenges and discuss possible solutions.

Themes:

• Methods of analysis - including data collection
• Citizen science
• Microplastics in water, land and air
• Microplastics human health implications

Introduction: Dr Fay Couceiro, University of Portsmouth

Keynote: Dr Ben Williams, Senior Research Fellow, Air Quality Management Resource Centre, University of the West of England

Session 2: Exploring the current issues of plastic use within the context of fashion and textiles and the role of plastics in the future

Description: An opportunity to discuss current issues of plastic use within the context of fashion and textiles. Each year, the industry uses 342 million barrels of petroleum to produce plastic-based fibres such as polyester, nylon or acrylic. This equates to 1.35 per cent of the globe’s oil consumption. Worse still, these plastic-based fibres are responsible for 73 percent of microfibers pollution in Arctic waters and, according to the Ellen MacArthur Foundation, the plastic packaging on which the fashion industry is largely reliant, is estimated to make up 26 per cent of the total volume of plastics created each year – 72 percent of which is thrown away. However you choose to measure its impact, the numbers are staggering. This session acknowledges these very pressing issues that the fashion industry and academia is currently facing.

We will bring together scholarly experts and practitioners in the areas of plastic use, materiality and design to share their knowledge and experiences with fellow academics and practitioners. Scholarly, conceptual and practitioner papers are welcomed, especially those that address the following themes:

Themes:

• Fashion lifecycles vs plastic lifecycles
• Alternatives to fossil fuel based plastics for fashion and textiles
• Recycling of plastics
• How can plastics fit within a sustainable future
• Solutions to microfibre pollution from textiles
• A transition to a circular economic environment
• Single use plastic in fashion retail
• Consumer intention behind recycled plastic waste product

Session 4: The Plastics That Made Us

Description: Focusing on the collections and exhibitions programme at the Museum of Design in Plastics (MoDiP), the only UK Accredited museum with a focus on plastics, this presentation will demonstrate how by learning from the past, manufacturers, designers, and consumers of plastics can make better informed choices. MoDiP's purpose is to use its Designated collection to develop understanding of the value of plastics within historical, contemporary, and sustainable contexts. Exploring the museum’s objects that encapsulate a variety of uses and activities - taking into account the clothes we wear, the games we play, and the environments in which we live - this keynote will show how valuable plastics, as a materials group, have been when used appropriately. It will also acknowledge the negative impact the poor use and disposal of plastics materials has on the environment and health.

Roundtable themes: The Care and Curation of Plastics

• Historical and contemporary cultural perceptions of plastics
• Curatorial relationships with plastics
• The seen and unseen uses of plastics
• Sustainability and the green consumer
• What can we learn about the future of plastics from their past?

Session 5: Creative Solutions to Global Challenges

Description: Arts-based methods are increasingly being used in academic research to explore lived experience from a grassroots perspective. Artistic methods democratise the research process and disrupt traditional academic hierarchies, often revealing diverse values, and enhancing understanding. When communities collaborate with researchers to find solutions, the results are more local, targeted and contextually sensitive.

This session will include past and present projects in the Global South, methodologies and workshops.

Themes:

• Community-based participatory research
• The range of arts based methods
• Working in different contexts
• Practical workshops

As you can see from the number of speakers, this was an inspirational and packed event with so many topics covered. I was so pleased to be a part of it and bring an historical context to the proceedings along with the panellists I was speaking alongside.

I learnt so much about the people living with the worst of the plastics pollution and the projects that are attempting to reduce the production and use of materials, those that are exploring ways to prevent the waste ending up in the wrong place, and those monitoring and / or removing it once it is there. It was good to see the use of artificial intelligence in a positive context too.

It was the kind of conference where there was so much to take in that you need more time to explore the subjects covered. I have no doubt that I will be spending lots of time over the coming weeks and months finding out more about the many speakers and the work they are doing.

Despite the serious subjects being discussed the event was extremely relaxed with a positive outlook. We had reception drinks on HMS Warrior on the first evening and a conference dinner on the second evening.  Conference dinners can be a little stuffy sometimes but this one had a festival vibe with a plant-based BBQ and live music making it much more suitable for networking.

Salter 59 kitchen scales

Once again flicking through the trade journals in our collection and recognising an object that we own has enriched our record with a wealth of information.  This time I was looking through an edition of British Plastics from February 1955 and I stumbled across a fabulous article about the manufacture of the Salter 59 kitchen scale.  This article has offered up a firm date and title of the object and some fabulous detail about how exactly the case was made and who did the moulding.

Salter 59 kitchen scales, AIBDC : 0_2337

Here is the article:

Three polystyrene mouldings for domestic scale

A great deal of progress has been made lately in the application of plastics to household appliances, especially where streamlined shape, appearance and ease of cleaning are essential properties. This recent trend is exemplified in the modern domestic scale where a number of new or redesigned models have plastics components; in particular polystyrene finding favour on account of the excellent finish obtainable with this material.

The Salter 59 scale uses high impact polystyrene for its scoop, general purpose for the housing, and general purpose for the dial cover, where the glass-like transparency of the material is of special advantage. The moulding is carried out by E. Elliott, Ltd. Birmingham, and the technique used to mass-produce three items mentioned is of additional interest in that all of the finishing, apart from a cementing operation, is carried out at the press.

The pictures on these pages (come and see the article if you would like to see them all) show the stages in moulding the Salter 59 case. Production is carried out on an 8-oz injection machine, using general-purpose polystyrene in a cream (yellow in our case) shade. Injection is at the centre top of the case where a square aperture is later punched out to accommodate a plunger when the scale is assembled.

Punching the square aperture from the housing after moulding, and, right, a housing placed in the jig for drilling in four positions

The circular aperture in the housing is produced by having a blank face on the mould (which closes on a bevel positioned half-way across this blank face); another interesting feature is the method of producing a slot at the rear of the housing by moulding a projection running on a taper.  Purpose of this slot is to accommodate a knurled wheel which allows the scale to be set (and reset) to zero.  About 55 lifts an hour are achieved, the cycle time being closely integrated with the finishing time. Weight of the shot as it comes of the machine is about 5 ¾ oz.

At the completion of each cycle the operator clips off the sprue and stamps out the square aperture on an electrically heated punch, the temperature of which accurately maintained by a Sunvic control system.  After this the housing is placed in a jig, which is designed both to hold the shape of the moulding as it finally cools and to allow the simultaneous drilling of four 1/16 in holes, two on each side; the purpose of these holes is to accommodate attachment of the inner mechanism of the scale. Drilling is carried out by four drills each operated by an air valve supplied from the normal press air line; a master valve enables the complete system to be switched in and out, and thus cutting out noise when the drills are not actually operating, and thus making the operator's job less fatiguing. The housing then wrapped in tissue and at once packed in a cardboard box for transfer to the Walsall works where the moulding dial cover cemented in.

Production of the dial cover is carried out on a 4-oz machine, using single-impression three-plate tool working with clear transparent material. Gating is at the centre of the cover, and to disguise the tiny scar at this point the mould is blasted over a small circular area, thus producing circle of matt finish in the centre of the cover when moulded. Weight of shot is 1 ½ oz. Removal of the sprue is interesting in that a tapered dowel provides a positive movement of the sprue in the tool, so that  after the stripping plate has cleared the moulding , the sprue can be removed backwards from the gate.

The dial covers are wrapped tissue and packed straight from the press and, as previously stated, sent away for cementing into the housing. Thus the handling of both is reduced to the barest minimum, thereby cutting down the possibility of rejects through accidental damage in the factory.

The scoop of the scale is run alternately with the housing.  A single-impression tool is used and the scoop is gated on the centre under-surface. The colour used is cream, and the weight of the shot is just over 3 ½ oz. The sprue is removed from the operator, who then packs the scoop in similar fashion to the housing. The scoop is embossed to provide graduations in fluid ounces and pints on the inside.

It is so interesting to see the number of different steps needed and the care given to the end product to ensure it arrived at its destination in good order.  I do love finding these fascinating articles.

Decarbonisation

Decarbonisation is a theme in our current exhibition, Reuse. 

Carbon footprints are a measure of the amount of carbon dioxide and other greenhouse gases released over the full life cycle of a product. They are notoriously difficult to assess because there are many factors that need to be considered. For example, extraction and processing of the raw materials, manufacturing, packaging and transportation of the product, useage (how long it is used for and whether it is reused) and then finally, recycling and disposal at end-of-life.

The environmental impacts associated with plastics are often generally much lower than that of alternative materials such as glass, metal and paper. However, there are several ways by which they can be further decarbonised. Incorporating recycled content, selecting biopolymers instead of plastics derived from fossil fuels or using carbon neutral materials are some potential transformational solutions.

All of these objects are sourced from plant-based materials rather than fossil fuels.

In the drive towards becoming net zero, businesses involved with plastics can also try to make efficiencies across their general operations, production processes and supply chains. They might consider switching to low-carbon technologies, using renewable energy sources, adopting closed-loop systems to minimise waste and choosing partners who also prioritise decarbonisation. When areas of unavoidable impact still exist, they might invest in guaranteed carbon offsetting projects, designed to reduce future emissions.

Plastics can play an additional role on this journey for all of us through their use in, for example, insulating products to make our buildings more thermally efficient, as components within ‘clean’ energy systems such as solar panels, and within electric vehicle technology and infrastructure. It is important that the material flow is both decarbonised and circular in order to be as sustainable as possible.
