Research
Controlled Environment Agriculture/Vertical Farming– The developments in the APGC, including working with global vertical farming companies, have brought intense focus on the emerging files of total controlled environment agriculture, including vertical farming. This approach exploits integrated systems to facilitate sustainable, local crop growth on a large scale and, via some of the grants identified below, are being shown to have many benefits such as significantly reduced water and nutrient use compares to filed and existing glasshouse systems, offer the ability to alter the taste, texture, appearance and nutritive value of a crop without and genetic manipulation, and if linked to renewable energy sources offer a route to decarbonising the crop production supply chain.
Organoleptic, bioactivity and functionality basis of plant-derived foods– the functional qualities, flavour, aroma, texture, visual appearance bioactivity etc are often the driving factors in food consumption. However, each of these parameters are multi-component and interrelated. However, through collaborations with geneticists in academic and industry organisations, who have unique germplasm segregating in organoleptic parameters, and by applying rigorous and concerted chemical, biochemical, physical and molecular biological approaches we are taking this area forward. Aligning this with the activities in Controlled Environment Agriculture/Vertical Farming makes this a central activity to the APGC.
Circular BioEconomy– The landscape for society, industry and policy is ever evolving but the last few decades have seen a sharpening focus on the key issues of climate change and the sustainable use of resources. This has led to the development of policies and initiatives around factors mitigating and adapting to climate change and activities, particularly industrial, that deliver equivalent or enhanced outputs but with reduced greenhouse gas emissions. All of this highlights a shift away from fossil fuel-based feedstocks and the requirement for sustainable/renewable resources and processes. This shift to alternative resources means the feedstocks will need to come from land- and marine-based systems. These new feedstocks could be grown (or harvested) or, as is the focus here, be bioarisings (wastes or co-products) from established rural economy processes such as crop and animal production. We have established a portfolio of approaches looking at agri-food bioarisings (waste or poorly used biomass) and how they can be valorised via biorefining technologies and ensure value is captured. This is another approach towards ensuring we transition to allow carbon economy
