Polymers are one of the most widely used materials in our day to day lives and are used in so many different products. Some of these are obvious like commodity plastics used in packaging, and other less so, for instance in electronics, cosmetics, drug delivery, nanomedicine to name a few. Polymers provide solutions to many problems, but environmental concerns exist about both the source of polymer starting materials and their waste management at end of life. Most synthetic polymers generated today are made from fossil fuels using petroleum-derived chemical feedstocks. However, petroleum is a finite resource estimated to be depleted within the next 50 years. Therefore, one of the key challenges with polymer production is to move towards renewable resources for their manufacture. For some applications precise control over the polymer architecture and composition is required and advanced polymer synthesis techniques can be used to achieve well-defined copolymer structures. Of interest here, block copolymers are polymers with distinct segments of differing composition. They can have interesting self-assembly behaviour when the blocks or segments have differing properties, with applications as adhesives, coatings, membranes, biomedical (e.g., drug delivery), lithography and nanoreactors. Due to advancements in polymer science in recent years, block copolymers are now being commercialised. However, these commercialised block copolymers are also derived from non-renewable petroleum feedstocks. Due to increased interest in block copolymers due to their interesting properties and use in value added application areas, and growing environmental concerns, the development of renewable block copolymers is an important challenge that this project will address. In this project we will prepare new polymers from renewable resources, with tuneable properties, which can be used in a range of applications including biomedical (i.e., drug delivery), paints, adhesives, and personal care products. By using starting materials derived from biomass, the polymers will be prepared from renewable resources. We will investigate using naturally occurring biopolymers, and vegetable oils to prepare new polymers. Through varying the vegetable oil and biopolymer starting materials and the structures of the copolymers, properties of the block copolymers will be varied allowing for potential use in a broad range of applications. Throughout the development of the new copolymers sustainability will be also considered when choosing which reaction conditions to use. In summary, this ambitious project will deliver new renewable block copolymers with well-defined structures using a combination of naturally occurring biopolymers and monomers extracted from renewable resources.

Terrestrial farming is the greatest driver of biodiversity loss, a major contributor to greenhouse gas emissions and water pollution, and faces its most transformational reform in 50 years to improve both environmental and economic sustainability. The new Agriculture Act, 25YEP, has commitment to net zero carbon emissions and policies to enhance environmental stewardship, sustainability and support the production of public goods. This project aims to demonstrate the socio-economic benefit of a world-leading 'terrestrial blue economy', contributing multiple public goods to reform UK agriculture. Combining high value shrimp aquaculture with farm-based renewable energy will provide a novel home-grown output with considerable but poorly understood economic and health potential. The public goods benefits of a switch from beef/sheep production to shrimp include lower greenhouse gas emissions, water pollution, and land use, freeing land for other public goods such as trees, biodiversity, biodiversity net gain, and recreation. Furthermore, co-locating self-contained, indoor shrimp production units with UK farm anaerobic digesters (AD) will maximise use of their (otherwise wasted) heat energy, enhancing sustainability and circularity of both industries. Extra income will also boost the farm-based renewable energy sector, helping the UK meet emissions targets. Shrimp is a healthy seafood with high protein, low calories, low fat, rich in vitamins, minerals and antioxidants, promoting brain and heart health. Warm water shrimp is already highly popular seafood in the UK, with 22,852 tons (UK retail £319M) imported annually from Central America and SE Asia. However, traditional overseas production is vulnerable to climate/disease crises, has high transport-related CO2 emissions, and often uses environmentally unsustainable practices, e.g., destroying up to 80 % of nations' mangrove forests which absorb and trap more CO2 than any other of Earth's ecosystems. They also provide coastal protection against storms and coastal erosion. There is also the problem of illegal use (or just misuse) of chemicals such as pesticides and antibiotics resulting in contaminant residues in some of the shrimp exported to the UK, EU and US that can cause health issues. This proposal aims to completely avoid these problems and ensure a risk-free, healthier and sustainable supply chain of this heart- and brain- healthy seafood for UK-consumers, by facilitating a major expansion of UK's shrimp RAS production sector which currently supplies equivalent to <1% of imports. We aim to co-locate RAS production with renewable energy sources on UK terrestrial farms. We conservatively estimate that if only 20% of the UK's current Anaerobic Digestor (AD) plants were adapted for shrimp farming, we could sustain 960 shrimp production units and harvest 5,520 tonnes of shrimp per year (~25 % of current UK warm water shrimp imports). With the rapid growth of AD plants across UK farms (10-fold increase since 2010), there is clear potential for truly sustainable, healthier, home-grown shrimp to provide the majority consumed in the near future, in addition to enhancing environmental stewardship, sustainability and supporting the production of public goods from UK agricultural practices. Importantly, this project will generate data to evaluate the true potential of sustainable UK shrimp production using renewable energy technology, as well as providing this shrimp industry with the necessary world-class scientific support. This project will therefore address 3 goals to transform the UK Food System: 1) increased environmental sustainability of farm practices (e.g., sustainable use of existing waste heat from ADs), 2) economically sustainable expansion of UK land-based aquaculture production & employment, and 3) establishing the UK as a leader regarding capability, expertise and innovation in co-reforming agriculture and aquaculture.

Like energy and automotive before it, UK freight transport is now on the cusp of a socio-technical transition away from fossil fuel dependency. This transition will require major investment to fleet and infrastructure, cause disruption to assets and business models, and will trigger significant reconfiguration. Whilst the scaling up of fossil phase-out is most likely to occur from the 2030s onwards, the next 10 years of investments are critical to enabling the transition, and to mitigating transition risks to the "hard to abate" freight sectors, and by association UK trade. Our concept to address this challenge is for a Network of broad but interconnected academic excellence integrated with key and leading stakeholders in freight decarbonisation, that collaboratively develops and applies knowledge and understanding of rapid freight decarbonisation. We will use this Network to collect and distil current knowledge, as well as to identify and de-risk the key remaining research challenges that can unleash significant freight-decarbonisation targeted investment and guide enabling policy. This Network connects five freight transport investments made by the EPSRC with a track record of a whole systems approach to decarbonisation of UK freight flows (international and national), and of closely integrating and embedding research with industry and policy makers alike. The Network's efforts will be guided by a number of features of UK freight transport including: (i) significant fixed infrastructure with long timescales for investment (ii) lack of consensus on the specific technological solutions for each mode (iii) a complex combination of national and international transport systems (iv) besides the road and rail network, a limited scope for public sector investment (v) Complex governance involving a mix of UK, EU and international (UN) regulation. The Network will align and integrate directly with UK government and existing initiatives including (i) Industrial strategy (ii) Clean Growth Strategy (iii) Road to zero (iv) Clean Maritime Council (v) UN agency fora (vi) World Bank's Carbon Pricing Leadership Coalition (vii) ongoing work on aligning investment to decarbonisation with: European Investment Bank, UK private sector institutions, IFC and IMF, and leading investment NGOs: 2 degrees investing, World Economic Forum, Global Maritime Forum, Global Shippers Forum, UK FTA. To achieve this Network's objective of unleashing significant investment for freight decarbonisation, it is organised into five multi-modal and cross-cutting thematic areas and executed through a three-step approach: Theme 1: Role of data and models for unlocking implementation decision making Theme 2: Managing macroeconomic, policy and technology uncertainty, whilst mitigating climate risk in investment decisions Theme 3: Fuel and propulsion technology pathways Theme 4: Aligning drivers for decarbonisation investment/policy with local (inc. air pollution), UK, EU and Global climate policy and integrating into private sector decision making Theme 5. Coupling the evolution of logistics with decarbonizing freight Step 1: Refinement of current knowledge and perspectives into a focused set of research questions covering each of the five themes Step 2: Commissioning of a series (~13) small projects which can develop further understanding of these questions and the methods suitable for addressing them Step 3: Distillation of the Network's knowledge, in combination with the outputs of the small projects, to produce a strategy to drive freight decarbonisation investment, and an agenda and plan describing a series of further collaboration and funding activity that can sustain the Network
