Global Food

Challenges


The Food and Agriculture Organisation (FAO) of the United Nations estimates that one-third of all global food produced is lost or wasted between farm and fork. In the UK, that translates to 3.6 million tonnes of food being wasted by the food industry every year. Food loss and waste is also a significant contributor to habitat and biodiversity loss. The current demand for meat and fish products is expected to see a 78% increase by 2050 and without positive action will further impact already depleted land and oceans.

Feeding the World
Globally, the rising pressure to meet the expected consumption levels for the ever-growing population estimates that more than 250 million metric tonnes of additional protein will be needed per year. This puts immense pressure on our current animal feed protein sources such as soy and fishmeal. The current land degradation, declining soil fertility, unsustainable water use, overfishing and marine environment degradation are all lessening the ability of the natural resource base to supply food without making considerable detrimental impacts on the environment.  


Reducing Food in Landfills
The environmental impact of food waste is already significant, responsible for 8% of global GHG emissions. When food is discarded, it’s not just the food, often still edible, that is wasted, but also the valuable resources that went into making it. Furthermore, when food decomposes in landfills, it produces a greenhouse gas, methane. This puts huge pressure on the planet as food losses and waste alone contributes to an estimated 8-10% of global greenhouse gas emissions. Putting this into perspective, if food waste were a country, it would be the third largest greenhouse gas emitter, behind China and the United States. The pressure is on to reduce the environmental impact of food production. So how will we meet this demand sustainably? The answer could be insects. Alternative efficient technologies and practices are being sought to better deal with organic substrates (waste) whilst also providing a sustainable source of animal feed. Enter insect farming and a bioconversion methodology, as some insect species can reduce organic waste through consumption and convert the waste into high protein biomass for use in animal feed as well as other products. Insects offer a unique opportunity to address several challenges: protein supply, increased human demand, and organic waste disposal.

Solution: 
Food System Reformation


Consumers increasingly expect the food and drink industry to deliver sustainability measures in their operations, in the products that they sell, and in their supply chains. Awareness of the food system’s contribution to climate change, deforestation, water stress, food waste and other sustainability challenges is on the rise, especially as part of the UN’s Sustainable Development Goals. There are therefore significant commercial and reputational benefits in taking action. Many global companies, including food retailers, producers, and

distributors have already made significant moves towards reducing their impact on the environment as part of UN SDG Goal 12: Responsible Consumption and Production and Goal 13: Climate Action. Schemes including ‘zero waste to landfill’ and reducing food losses and waste in the supply chain are making positive impacts in the industry, along with collaborating with suppliers, retailers, and local governments to advocate for system reform to address food waste and mitigate climate change. 

But is that enough? 

Reduce:
Reducing food waste by half would avoid 1.5 gigatons of carbon dioxide equivalent emissions per year by 2050, but with the growing population and expected increase in food demand to be 60-70% by 2050, how can the food industry ensure they continue to meet demand, whilst also adhering to the global sustainability drive? 

Repurpose:
Turn organic side streams into high-value feed ingredients. Repurposing surplus food and converting it into animal feed avoids greenhouse gases generated from landfill and potentially reduces deforestation. As insects can eat a wide range of organic materials, they are perfect for dealing with production line side streams, discarded foods or agricultural wastes. Praised for their high-quality protein content, in a natural food chain, insects take care of recycling wasted nutrients, so they don’t mind food waste, surplus/rotting crops, discarded grains, or even manure. In this way insects contribute to the circular economy Today, this sustainable solution can be realised on a large scale. Repurposing surplus food is therefore a solution to the growing levels of bio waste as well as a solution for sustainable proteins.

Redistribute:
Redistributing surplus food waste into animal feed and other high value products via insect bioconversion contributes to the circular economy and allows food waste to re-enter the food cycle without the emissions of greenhouse gases. Insects also need much less water, land, and energy to produce the same amount of feed as soy and fishmeal, the popular protein source globally for poultry, bovine, and fish. 

Insects Reforming the Food System


As a largely untapped and under-exploited method, insect bioconversion (the method of converting food waste into animal feed via insects) offers a unique opportunity to address perceived challenges and mitigate the environmental impact in obtaining protein sources. When dried, insects contain up to 50% of high-quality protein as well as necessary vitamins, fats, and amino acids. They are also rich in antimicrobial, medium-chain fatty acids, depending on species, which have proven gut health benefits. Insect meal could help reduce the UK’s future soy imports, a product that is expected to see a 78% increase by 2050, by 1/5 if scaled up, reducing pressure on critical production landscapes as the sourcing and production of soy has increasingly been linked to deforestation in places such as South America.

How Does it Work?

Insects - Black soldier flies (BSF), Hermetia illucens, can valorise a wide variety of organic side streams and residues into high-quality and sustainable ingredients for application in animal feed products. Our team of experts can help you realise the potential of your waste, conduct lab trials, pilot, and scale your product, and help reduce risk. 
Our solutions cover feedstock preparation using all kinds of organic residues, rearing of the larvae, their processing into protein meal and lipids, the quality and safety of insect-derived products, as well as the use of the rearing residue and insect frass as a fertiliser.

Fera can provide a range of solutions to address corporate sustainability goals including reducing food waste, reducing GHG emissions and mitigating climate change by redistributing food industry side streams, which would otherwise go to waste, through the transformation of organic residues into quality ingredients for animal feed, industrial oils, plastic materials, and fertiliser. We cover the entire supply chain from feedstock handling to rearing, separation and extraction.

Timeline
Fera leading key research into industrial insect applications

The following timeline illustrates key projects led by Fera and important regulation changes in industrial insect applications.

From 2018-2020, Fera chaired the UK Task & Finish Group on Insect Biomass Conversion representing key stakeholders across the insect biomass value chain

The Insect Biomass Industry for Animal Feed: The Case for UK-based and Global Business

 
Members of the Insect Biomass Task & Finish Group represent key stakeholders across the Insect Biomass value chain and are committed to collaborating in order to deliver insect production at scale in the UK. The Government and its central agencies have a significant role to play in realising this innovation for UK-based and global business given its alignment with the UK Global Food Security Programme and the circular economy. All members have agreed that the following actions are key to enabling the realisation of a new insect biomass conversion industry for the UK. 

There is a need for Government to act swiftly to ensure the UK does not lose further ground in this rapidly developing global market. EU-Exit provides an opportunity rather than a barrier to accelerate the development of a UK based and global business. Reducing food waste by half would avoid 1.5 gigatons of carbon dioxide equivalent emissions per year by 2050, but with the growing population and expected increase in food demand to be 60-70% by 2050, how can the food industry ensure they continue to meet demand, whilst also adhering to the global sustainability drive?
