WRAP states that the UK wastes £19 billion worth of food a year in production and consumption sectors. 70% of the UK's wasted water footprint is used in the production and consumption of food and drink. Globally, a third of food is wasted - the scale of the problem cannot be understated.

Agrigrub's goal is to fully utilize this food waste, diverting a costly waste stream away from landfill, incineration or anaerobic digestion into a process which produces high value outputs. The engine for this process is the Black Soldier Fly larvae, an insect species adept at growing on a variety of organic waste types. Waste fresh produce can be used to create protein and calcium rich animal feeds. The full breath of food production and processing is utilised, we work with farmers, distribution centres and retail outlets to increase the sustainability of their supply chains. In addition to the insects themselves, their droppings and casings (frass) make a rich organic fertiliser which also reduces insect damage and pathogen load on crop plants.

Black Soldier flies larvae are natural born nutrient converters, with millions of years' worth of experience in transforming fruit and vegetables into biomass and frass. The gut of the BSFL contains a wealth of beneficial biochemistry which can be passed onto the soil through frass. The main components of their casings (18% of frass) are chitin and chitosan. These complex molecules act as a chelating agent, making micronutrients more available to plants. Chitin and chitosan also elicit an induced systemic effect in crop plants, analogous to an immune system response in animals. This induced systemic effect can be harnessed as a bio-repellent, allowing the plant time to "draw up its defences" before an attack. Chitin and chitosan has been proven in the lab to be effective against a variety of pests and diseases, but previous sources of chitosan were scarce and extraction methods were prohibitively energy intensive. In contrast, frass is produced from waste with minimal energy input, turning a low value and underused resource into a high value, sustainable and readily available product.

Overall, AgriGrub's process is a significant positive disruption to the current food waste landscape, and an innovative way of turning waste material into a set of valuable, sustainable resources. This philosophy perfectly aligns with the Innovation Hub vision for reducing waste and increasing efficiency within the agricultural sector.

Current projects

AgriGrub has received financial support from the Eastern AgriTech Growth Initiative for a one year research and development looking at the route to scaling operations to meet UK demand. We are working in collaboration with InAgro and Vives as part of the Interreg 2 Seas project and industrial partners to examine scaling methodology.

We are also collaborating with G's, Delfland Nurseries and other growers to understand how frass can be most effectively used in the agricultural and horticultural sectors, with trials currently running on a variety of pest species.

Aponic have designed and developed a vertical aeroponic commercial food growing system that saves 90% of the water usually poured on the ground and grows 30% faster and gives larger crops yields compared to traditional growing methods.

The multi award winning system uses so little power that it can easily run 'off grid' on solar power and rain water. It recycles its water and nutrients ensuring that they are fully used in the growing process and do not get washed away.

The vertical design turns acreage into volume and makes planting, tending and harvesting a simple task, which can be managed by workers in a standing position. This ensures clean, easy to harvest, consistent crops and cropping cycles even on top of land that was previously unusable or has been taken out of normal production .

The system can be further automated to reduce labour costs and large capital equipment costs and allow precise control of nutrients and produce the perfect crop every time to enable all farmers to create low input, high volume, high value output produce that they have never been able to grow in this country before.

Jason Hawkins-Row is the Aponic CEO and product designer. He started out as an aviation design engineer and then taught himself to be a programmer which took him all over the world where he founded a rainwater recycling project in Australia and fitted indoor fishponds in large airports. This experience highlighted the simplicity and brilliance of nutrient cycling and the intricacies of water management and finally led to the development of a truly sustainable food production system that can be used all over the world in wide variations of climate to grow large quantities of extremely high quality food.

Projects and Aspirations

Aponic have installed a commercial growing system and an aquaponic system at the Innovation Hub which is currently trialling indoor growing of peas, beans, lettuces, pak choi, wasabi, strawberries and tomatoes. We are comparing growth to soil grown plants of the same genotype and then investigating the possibilities of any difference in nutritional value between the two methods.

We are collaborating with NIAB to obtain an InnovateUK grant to roll out sustainable intensification of small to medium scale farming for developing countries so that individuals, villages and commercial growing operations can increase local nutrition and employment without damaging their local environment and minimising impact on climate change.

Within the Innovation Hub we are also collaborating with Entomics, a company developing systems to convert food waste into usable insect protein. Waste insect products are used to feed fish. The fish waste is recycled back to feed crop plants. This is a great opportunity to demonstrate a sustainability project which will yield high quality fish and vegetables to the table using waste food, rainwater and solar power.

The Aponic Vertical Growing System is the first in a series of products that will grow to encompass many other crops and we hope to develop them and trial them with NIAB in the future.

Each year, wasted food represents US$1 trillion of lost value, and leads to 3.3 billion tonnes of carbon emissions the FAO estimates that global food production must increase by 70% to feed the world's rapidly growing population by 2050. This has forced a fundamental rethink around the way we source high-quality animal protein, as well as nutritious fruits and vegetables.

Entomics Biosystems' innovative solution is to 'close the food waste loop' by transforming organic waste into sustainable agricultural inputs, using an indigenous UK insect, the Black Soldier Fly (BSF) as a conversion catalyst. BSF larvae efficiently convert 95% of organic waste into complex fats and proteins in their bodies. Leveraging our novel post-processing technology, we refine these compounds into aquaculture feed and organic fertiliser in a cheap, scalable and sustainable manner.

Overall, this is a significant positive disruption to the current food waste landscape, and an innovative way of turning waste material into a set of valuable, sustainable resources.

Thus, the Entomics philosophy perfectly aligns with the Innovation Hub vision for reducing waste and increasing efficiency within the agricultural sector.

Celbius helps customers to improve their bioprocesses by exposing liquids and slurries to ultrasonic energy. The energy is delivered to the process stream whilst flowing through a sonic pipe and lowers production costs for extractions, fermentations and biotransformations by enabling faster reactions and higher yields. Key applications for the agricultural industry include extraction, for example for natural colours, antioxidants and other bioactives.

The technology improves the yield of biogas and bioethanol (fermentation), and may be used for other applications where efficient mixing, material drying, cleaning or novel product formulation is needed.Laboratory experiments are first performed to quantify the benefit of ultrasound in the process. Following this, the technology is demonstrated in a full scale 10L flow cell prior to installation in a manufacturing process. A variety of business models are available to suit the customer.
