As individuals, our daily routines rely on plastics in their many shapes and forms, whether as long lasting components of our homes and vehicles or as essential elements of important advances in medicine, water purification and infrastructure, or as packaging for cosmetics, food, drink, toiletries, cleaning products and healthcare products. These plastics are unrivalled materials: they are inexpensively synthesised, lightweight, recyclable and often deliver unmatchable performance. However, our love of plastics comes at a significant cost, as the environmental impact of these materials is massive, and growing. Genuinely sustainable plastics will need new forms of resource efficient materials, smart supply chains, and sustainable business practices, requiring holistic and integrated solutions. This proposal brings together diverse groups from across The University of Manchester to tackle this grand challenge of plastic waste. We seek solutions to the challenge of plastics pollution through an integrated approach that explicitly couples Manchester's strength in sociotechnological understanding and influence to our industry-guided solutions across chemistry, safety, materials, engineering and social sciences. The goal is to create a concerted, focussed consortium of diverse individuals who will lead stakeholder conversations, pitch multi-disciplinary projects that build from our strengths, and incubate these projects into translatable solutions. Through these collaborative efforts we will develop 6-12 projects building from our diverse expertise in urban recycling, sustainable business models, invisible plastic waste, valorising waste plastic streams, and new degradable polymers, and through them aim to: i) reduce the need for plastic by addressing demand, ii) improve the materials used to deliver better performance and clean degradation, iii) demonstrate new methods for recycling soft and mixed plastics/non-plastic films (currently very difficulty) and removal of micro plastics from source; and iv) create smart circular economies that allow users to take ownership of and reduce plastic waste. A multidisciplinary team of researchers at The University of Manchester will lead a portfolio of projects to tackle this grand challenge. Activities will be aligned with the first-of-its-kind Greater Manchester plan to drive down single-use plastics by 2020 and use the city-region as a living lab to innovate at speed and deploy solutions at scale.

Our current approach to packaging food and other products is not sustainable; being primarily based on single-use plastics that, when disposed of incorrectly, cause significant harm to the environment. Recycling, while clearly a better option than landfill, also has its limitations - e.g., the functional properties of plastics degrade as a result of the recycling process. And reducing consumption is only possible to a certain degree. It is therefore clear that we - that is science, industry, government, and society - need to find ways to enable people to reuse packaging, such that it stays in circulation longer before ending up in the waste stream. The proposed research, led by a multidisciplinary team of scientists working in partnership with key stakeholders, will explore models of reuse and provide the insights needed to enable a wholesale shift toward reuse. Our research will be structured around five work packages (WPs). WP1 will examine the language that people use to describe different types of plastic and actions associated with their reuse / disposal. We will study the extent to which public understanding of plastic and actions is aligned with that of stakeholders (e.g., local authorities, manufacturers), and how language can be used as a tool to promote changes in thinking and behaviour (e.g., by describing materials and actions in different ways). WP2 will look at both historical (e.g., doorstep delivery of milk) and contemporary (e.g., supermarket refill stations) models of reuse, as well as standardised models of packaging (e.g., tin cans) to identify what role reuse might play in the future and what factors might facilitate and/or impede this. WP3 will identify what people might be willing to reuse, when, and why. We will also consider the point at which deterioration in materials and / or potential contamination makes reuse unacceptable; and, critically, how such decisions might be shifted in an effort to promote (appropriate) reuse. WP4 will use life cycle assessment to identify the environmental impacts of a range of different reuse models in a range of different contexts; thereby providing the data needed to accurately determine which model of reuse is "best". Finally, WP5 will investigate the suitability of current and emerging polymers, and other materials for reusable packaging by simulating repeated washing and potential contamination by ingredients in food, personal care, and household products. Together, the outputs of the proposed research will be an understanding, based on robust scientific data, of when and how reuse models for plastic packaging make good sense. For example, our research may lay the groundwork for promoting a societal-shift in thinking toward buying the product, but renting the packaging. Our approach recognises that a new system that prioritises reuse, and then recycling, of durable materials requires a step change in behaviour and that truly creative and novel ideas occur at the interfaces between disciplines, when different perspectives are brought together in an open and 'safe' environment. The applicants have demonstrated their ability to work together as a multidisciplinary team alongside key stakeholders as in an on-going single use plastics project. The present proposal describes the research needed to translate this expertise and initial ideas into scientifically rigorous and joined up data that can provide the basis for delivering reuse as a national (and potentially international) vision; thereby, preventing plastic from entering the environment and stimulating more sustainable business, supply chain, and economic models.

The 3SIP2C project is focused on quantifying the types and amount of plastic waste entering the coastal margin of Vietnam, and understanding the pathways and destination of that plastic into the wider environment and marine life, and how this plastic impacts upon business activities such as aquaculture, fisheries, tourism and coastal communities. Vietnam's 3260 km coastline stretches across 28 coastal provinces and supports rural livelihoods that are engaged in coastal tourism, fisheries and aquaculture industries that are between them worth more than US$17 billion per year. These industries are themselves contributors to the plastic waste problem, but are also impacted by that waste, such that it represents a risk to civil society and business performance, health and safety. Our project will focus on plastic waste comprised of large (>50 mm), macro- (5 - 50 mm) and micro-plastics (<5 mm). The project is organised into five work packages, with Capacity Building and Engagement acting as the unifying theme throughout our proposed science, policy and governance programme. Our work packages flow from a fundamental understanding of the physical processes that transport plastics into coastal areas using 3 dimensional particle tracking models that account for seasonal changes in transport processes, and that account for the effects of tides, waves and freshwater inundation on these processes. We will couple this with a broadscale sampling strategy designed to gain insight into the characteristics and quantities of those plastics and the contaminants that are transported into the coastal system. This will be linked to a work package focused primarily on understanding the impacts and causes of large plastics on businesses and civil society associated with coastal communities, which will involve engaging citizens in collection of data on the distribution of large plastic through 'fishing for plastic' and the use of App technology. We take a deeper dive into the pathways by which macro and micro-plastics interact with the environment and interact with organisms, particularly those relevant to businesses such as fisheries and aquaculture. We will use experiments to understand how those plastics and their associated contaminants relate to health and disease threats in e.g. coastal aquaculture systems. We will interrogate the existing national and international legislations and policies that address the issue of plastics in supply chains and investigate where shortcomings in the integration of policies leads to shortfalls in their successful implementation. Finally, using a broad suite of techniques such as discourse analysis, focus groups, round-table discussions, gamification and citizen science, we will greatly increase awareness of the issues associated with plastic pollution and the effective solutions that could reduce its occurrence or its impacts on society. This engagement will interface with citizens at local, regional and national levels, and with managers and Government officials in relevant ministries. This proposal is ambitious with a multidisciplinary team from 8 research institutions and 7 partners in Vietnam covering all regions of the coastline, and HWU in the UK. Our engagement, impact and delivery are further strengthened by strategic partnerships with the wider non-academic collaborations through retailers (The Cooperative, UK; Sainsbury's), major seafood importers and processors (Labeyrie Fine Foods - Lyons Seafood) and a Vietnamese business consortium (IDH-Vietnam) and Vietnamese NGOs Centre for Marine Life, Conservation & Community Development (MCD), and global NGOs the Global Ghost Gear Initiative (GGGI) and Global Aquaculture Alliance (GAA). These partners provide the necessary access, expertise and impact translation to realise potential solutions that deliver demonstrable reductions in the causes and consequences of plastic waste in the environment.

One Bin to Rule Them All is an innovative, interdisciplinary research project focused on developing a streamlined standard for plastics recycling which can be rolled out across UK homes, businesses and urban infrastructures. Working with stakeholders from across the plastics supply chain, including manufacturers, retailers and consumers, the project prioritises the value in plastic waste materials to ensure more effective and efficient pathways for recycling. Thus, reducing overall plastic waste and ensuring that future plastics are produced from higher recycled content. David Attenborough's Blue Planet II has highlighted the urgent global need to address plastic waste, pushing the issue into the forefront of the public mind. Whilst retailers and manufacturers are focused on improving the recycled content of their packaging, there is simply a lack of quality recyclable material available in the UK. Inadequate recycling infrastructure causes 60% of single use packaging to be exported, much of which is then incinerated. Not only is this a waste of valuable recyclable materials but there are significant environmental impacts involved in moving such waste across the globe and then burning it. One Bin will develop and integrate modern recycling technologies and processes in order to eliminate plastic release into the environment. This will be achieved through three interdisciplinary and interrelated work packages: Work package 1, led by material science, will create a hierarchy of plastic packaging to determine the optimal route for capturing and retaining value in plastic waste through re-use, mechanical recycling or chemical recycling. Work package 2, led by management science and economics, will design and then trial innovations for One Bin business models along the plastic packaging supply chain, identifying new business opportunities and pathways to design out waste. Work package 3, led by social science, will examine consumer engagement with One Bin and potential barriers to adoption through a consumer trial of the One Bin system, pre and post trial consumer interviews and a focus group with key stakeholders. By recognising and releasing the value in plastic waste, and standardising the current UK plastic waste management system, One Bin will overcome the current complexities surrounding plastic recycling and contribute to the UK Plastic Pact goals. The potential benefits from the project are significant, including: a) Reducing plastic release into the environment through enabling the creation of a truly circular plastics economy and a long-term elimination of plastic release. b) Creating an easy-to-use, standardised waste system for consumers that can be rolled out across the UK and incorporated into households, work places and leisure settings. c) Releasing and achieving economic value by identifying the most efficient recycling pathways and business models for different types of plastic.

Catalysis is a core area of science that lies at the heart of the chemicals industry - an immensely successful and important part of the overall UK economy, where in recent years the UK output has totalled over £50B annually and is ranked 7th in the world. This position is being maintained in the face of immense competition worldwide. For the UK to sustain its leading position it is essential that innovation in research is maintained, to achieve which the UK Catalysis Hub was established in 2013; and has succeeded over the last four years in bringing together over 40 university groups for innovative and collaborative research programmes in this key area of contemporary science. The success of the Hub can be attributed to its inclusive and open ethos which has resulted in many groups joining its network since its foundation in 2013; to its strong emphasis on collaboration; and to its physical hub on the Harwell campus in close proximity to the Diamond synchrotron, ISIS neutron source and Central Laser Facility, whose successful exploitation for catalytic science has been a major feature of the recent science of the Hub. The next phase of the Catalysis Hub will build on this success and while retaining the key features and structure of the current hub will extend its programmes both nationally and internationally. The core activities to which the present proposal relates include our coordinating activities, comprising our influential and well attended conference, workshop and training programmes, our growing outreach and dissemination work as well as the core management functions. The core catalysis laboratory facilities within the research complex will also be maintained and developed and two key generic scientific and technical developments will be undertaken concerning first sample environment and high throughput capabilities especially relating to facilities experimentation; and secondly to data management and analysis. The core programme will coordinate the scientific themes of the Hub, which in the initial stages of the next phase will comprise: - Optimising, predicting and designing new catalysts - Water - energy nexus - Catalysis for the Circular Economy and Sustainable Manufacturing - Biocatalysis and biotransformations The Hub structure is intrinsically multidisciplinary including extensive input from engineering as well as science disciplines and with strong interaction and cross-fertilisation between the different themes. The thematic structure will allow the Hub to cover the major areas of current catalytic science
