Opportunities for innovation with rapid growth in Controlled Environment Agriculture

  • January 27, 2020
  • 7:02 am

‘Plant factories’ – or vertical farms – outperform even the most efficient greenhouses in terms of energy efficiency and also achieve higher productivity for all other resources – water, carbon dioxide and land area – research by Luuk Graamans of the Wageningen University & Research and a speaker at the Agri-TechE Controlled Environment Agriculture conference has found.

“The urban population is set to increase to 6.3 billion by 2050 and this will place increasing pressure on supply chains,” Luuk explains. “One proposed solution is a closed production system, that maximises resource use efficiency by adapting the interior climate to provide uniformity and limiting the interaction with the external climate.

“A shortcoming of this system is the need for artificial illumination and high demand for cooling and vapour removal; creating a high energy load. The viability of plant factories depends on their resource productivity.

“Our research shows that when compared to greenhouse , a plant factory produces dry matter that is higher and more consistent and uses resources more efficiently.  This could be further improved by increasing the production layers, enabling more growing area on the same amount of land.”

Significant investment driving innovation in technology and business models 

Opportunities to radically rethink food production systems is one of the drivers for the rapid development of Controlled Environment Agriculture and technologies for vertical farming.

The industry is growing up and attracting significant investment – it was worth £1.72bn in 2018, with experts predicting that will rise to £9.84bn by 2026, according to reports presented to the All-Party Parliamentary Group on Science and Technology in Agriculture.

This growing market creates huge opportunities for innovation – in the construction of the growing units,  improvement of smart water usage,  lighting recipes to deliver all year growth, breeding to optimise rapid production, technologies for micro-control of the growing conditions. The current CEA systems are power hungry so improving efficiencies in order to  reduce the cost of production is vital.  Produce must compete in price with imported land-based alternatives.

Within the key players there is also divergence in business model.  Many believe the future is in scale, creating large production units close to logistics sites to enable ‘growing to order’ and rapid delivery. Others are looking more at the ‘dig for victory’ model, involving city dwellers in the production of their own food.

At the Agri-TechE Controlled Environment Agriculture event we have leaders in the field with speakers that include:

Kiryon Skippen of investment firm Capital Agri International comments: “I think CEA will provide a solution, but not on its own, it has to be part of the bigger picture. We are not leaving land-based food production behind.

“Also, the systems need to be properly de-risked, while indoor farms provide ideal growing conditions for plants, they are good for pests too. Systems in Asia are ahead of us as they’ve built systems more conservatively and then, year on year, tweaked and build them up. A more haste less speed approach.”

Jack Farmer, co-founder of LettUs Grow – developers of aeroponic systems. “We are working with key players to boost productivity and crop quality at scale.”

LettUs Grow is  working on a farm management system, Ostara, that uses powerful data on biological growing conditions to enable automation of facilities. The software can also be retrofitted into more traditional glasshouse environments.

Jack sees synergy between the existing horticulture business model and advances in CEA: “Essentially, vertical farms will prove complementary to glasshouse horticulture, with technology increasingly being shared between them.”

Jock Richardson of Growpura – his technology is designed for big production facilities. It uses hydroponics in a clean room environment and features an automated moving system to allow movement of the plants.

“There is a place for multiple solutions in CE, ” Jock comments. “We are going to see continued invention for small scale hydroponics, but on the industrial end the challenge to be broached is how growing operations are scaled.”

Mira Merme, co-founder of Netherlands-based OneFarm, explains that light spectrums and wavelengths are varied depending on the plant, and its lifecycle stage. The falling cost of LEDs is enabling growers to experiment with lighting recipes designed to optimise plant growth.

Mira says: “It’s like with human beings, we don’t need the same food throughout our growth cycle. Plants are the same.”

Johnathan Ransom, Square Mile Farms

Johnathan Ransom of Square Mile Farms started with the concept of ‘flat pack farms’ for urban areas and now offers farm installations to big businesses, to help them achieve their sustainability and employee engagement goals. After receiving an invitation from British Land, the company opened its flagship farm in February 2019 at Paddington Central.
