With the rise in the planet’s population around 60 million people per year, it is an issue that cannot be ignored.
There are several ways, each with varying degrees of difficulty, to enhance the efficiency of food production. These include tackling climate change, increasing the availability and fertility of land and improving the supply of water. However, an important element of food production which must be addressed immediately is the further optimization of crop yields as it will be a hugely significant factor in ensuring the 2050 target is met.

It is important to recognize that, in addition to the demand for more food, the desire for choice and variety is also growing. This is especially the case in developing countries that are adopting western, middle-class consumption habits such as the desire for a greater variety of food types and outlets in which food is served and consumed.

For instance, an average French fry plant produces 140.000 tons of French fries per year. By increasing yields by as little as 0.5 per cent through modern sorting technologies and techniques, a processor could take an estimated 90 truck-loads off the roads (assuming an average truck capacity of 25 tons).

It is important to highlight that this principle can be extended and implemented in all areas of food production. This is especially relevant since the United States Department for Agriculture (USDA) recently claimed that 31 per cent of American-grown food was not available for human consumption at retail and consumer levels. With a commitment to yield optimization, industries can help minimize this waste.
In terms of volume, the same report stated that over 51 million tons of food was lost in America. In monetary terms, this waste represented over $161bn (€145.3bn) as purchased at retail prices.
To help overcome this, the food sorting industry is investing in its technological development to ensure that efficiencies continue to be made. For example, the TOMRA 5B sorting machine is a system that not only sorts to customers’ specifications, but also provides them with an increasing supply of data and easy-to-interpret statistics which can be used to improve future yields.
TOMRA’s smart surround view can reduce false rejections by 20 per cent, increasing exponentially the amount of good final end product, in turn limiting waste.
The improvement in yield enhancing technology is not simply about ensuring food can be used for its initial purpose, it also identifies what produce can find its way into the food chain with an alternative use.
These improvements, as delivered by the TOMRA 5B sorting machine, will result in produce that would once have been identified as waste being recovered. A food type that does not make the grade for sale in its original form can be recouped for the creation of potato flakes, tomato sauces or other alternatives. It can also be sold as a grade B product, ensuring that waste is reduced at every stage of the process.

Alongside this, the population growth of developing nations - especially those in Sub-Saharan Africa which, according to the FAO, is expected to grow by up to 108 per cent - means that plans for improved yields in these economies must be tackled sooner rather than later.
The use of ever-improving technology to directly increase yields is a move in the right direction. However, the next generation of food sorting machines will be able to provide vital information which will not only increase yields, but also look at improvements further down the production line and in future seasons.
If a food processor was to notice depressions in yield in a particular area of the process, the results taken from the sorting machine could create a solution to easily identify and form actions earlier in the food growing process. Armed with this data, food processors are able to formulate plans to overcome present issues.
If the world is to meet the expected demands for food by 2050, and to make further improvements as the population continues to grow beyond that date, it must tackle the issue of improving yields quickly. By investing in sorting technologies and machines, food manufacturers and processors will be able to not only satisfy the need for increased volumes of product, but also increase their revenues.
The global population has been expanding rapidly for many years, standing at around 7.3 billion in 2016. This brings with it a number of challenges around global sustainability, including the need for more food.
The outlook should be regarded as a positive one. The assistant director general of FAO, Hafez Ghanem, said that his organization is “cautiously optimistic about the world’s potential to feed itself by 2050”. With continued developments in food sorting technology, it has every reason to be.
