Partnering with Waitrose to use Welsh grasses for food packaging

Although CARIAD's focus is on food security, we are an integral part of WINR, the Welsh Institute for Natural Resources. One of our partner units in WINR is the BioComposites centre (BC), which focuses on “green chemistry” and bio-based alternatives to synthetic materials. They have just won funding to lead a project with the Institute of Biological Environmental and Rural Sciences (IBERS) at Aberystwyth University, and informed by industry partners including Waitrose, to use Welsh ryegrass to create sustainable products for the food packaging and cosmetics industries – the Sustainable Ryegrass Products (STARS) project.  STARS will see a biorefining process used to isolate and extract sugars and other components from ryegrass and convert them into low carbon products. These include biofuels, platform chemicals and pulp-moulded packaging products for retail applications such as food packaging.

Funding of almost £600,000 from the Welsh Government's Academic Expertise for Business (A4B) programme is supporting the project. A4B is a six-year, £70m programme of support aimed at unlocking the commercial potential of Wales' Higher and Further Education Institutions. Managed by the Welsh Government, and supported by EU convergence funding, it works closely with Wales' academic institutions, to help harness the knowledge, expertise and facilities that exist within academia and convert this into economic benefit for Wales. The Welsh Government is highly supportive of two Welsh institutions working with a wide range of partner businesses, both indigenous and multi-natonal, on a novel project with commercial potential.

The project will collaborate with six industrial partners representing all links in the SME supply chain - from biomass cultivation and harvesting to processing and commercial end-use - and will demonstrate the production of these materials at a pilot scale.

To inform the process, Waitrose will research public engagement in the bioeconomy and the adoption of green products. They see a natural synergy between this project and their own approach to “Treading Lightly” and reducing their environmental footprint. Waitrose are keen to move to easily recycled fibre-based packaging for foods, where this can show positive environmental benefit, and a key element of the project will be engaging with the public from an early stage to ensure they are delivering solutions that meet their needs.

We believe the complementary expertise of the two Welsh universities and of the industrial partners will be the key to success. A key objective will be the creation of products with lower carbon output than those produced from oil. Activating a green industry in this way is a global aim, and we hope to demonstrate an integrated approach to land utilisation. We don't want to displace existing agricultural activity, but aim to provide farmers with an opportunity to diversify and find alternative applications for surplus grass produced in the UK. Through forging relationships with world-class organisations with significant market insight, the project offers a real possibility to commercialise a number of product streams from ryegrass.

The project will take previous research in this area to the next level, i.e. a demonstration at a commercially relevant scale using Bangor’s existing pilot-scale facilities in the BEACON project, and working with a supply chain to bring this concept to the public’s attention.

Rural poverty – not just an overseas problem

With our long history of working with smallholders in Africa and South Asia, we tend to forget that rural poverty can also be disastrous for farmers in Europe and the USA.

This has been brought home by the excellent TV series on the US dustbowl in the 1930s, when years of expanding wheat production in the Southern Great Plains were brought to a halt by prolonged drought, and the inappropriate technology in use caused massive wind erosion of the soil. Combined with the economic depression of the time this led to a vast displacement of people.

Closer to home and more up-to-date, it was a shock to read that Oxfam, better known for their work in famine zones in Africa, were working on poverty among upland farmers in Upper Teesdale in northern England. The UK uplands are areas, sometimes remote, of high rainfall, cold weather and poor soils, where traditional farming methods largely depend upon the rearing of livestock for later fattening in more fertile lowland farms. Their report has some startling conclusions.

Farmers’ incomes fluctuated, largely due to circumstances beyond their control, and relied upon government support as well as sales of livestock. This resulted in situations when bills could not be paid, farmers could not afford food, or had to reduce the inputs such as fertilizer and livestock feed, and were unable to invest in improving their farms. Average farm incomes were about ¾ of the minimum level needed by an adult to live in a rural area, and some were only half this. Farmers in poverty had no insurance, no pensions or savings, and depended on off-farm income for survival. They felt vulnerable to landlords and to the banks, and some had developed mental health and well-being issues as a result of the poverty. Farmers were becoming older as younger people left for (better-paid) jobs in towns and cities. The report noted that the problems were becoming worse.

These would all have been recognised by the dustbowl farmers of 1930s USA, and by smallholders in developing countries the world over. They are all situations our group have become familiar with over the years, but we did not expect to see them in the UK which, despite the recession, is still one of the world’s largest economies. The question is “what is to be done?” The Oxfam report recognised three key issues: raising awareness and increasing take-up of available State benefits; improving skills development and generating off-farm income; and addressing exclusion from mainstream services, in particular healthcare, and suggested half a dozen action areas to address them. These included the transfer of livestock skills to the next generation; encouraging young people to remain in the hills by providing training and employment; and thinking through the unique features of upland farming environments.

Upland farmers in the UK are fiercely individualist, and want to carry on making a living from their traditional livestock raising. Historically, this has been recognised by government, who also recognised that this was not easy in harsh hill environments, and provided subsidies to guard against low prices and funded research organisations to develop technologies for improving production. However, times have now changed, and there is a greater focus on using subsidies to maintain biodiversity and on the provision of a more general range of ecosystem services. That is not to say that livestock production is unimportant, it is and must remain so if the character of the hills is to be maintained. The challenge is to develop a means of funding farmers to produce what the nation and its people want from the hills and uplands, while maintaining biodiversity, protecting the environment and sustaining communities in times of austerity. Whether the government has the will to do this remains to be seen.
