Lesson 5: Sustainable innovations shaping the food system

Zero emissions farm tractors: The first ammonia-powered zero-emissions tractor successfully completed its first demonstration at the beginning of 2022. The diesel engine replaced with an “ammonia to power” system which converts the energy-dense chemical into hydrogen, which then powers a hydrogen fuel cell.

Modular stackable urban farms: Τhe farming system is achieved using a series of modules that allow for food cultivation in small urban areas and are designed to look like cubic trees in the city landscape. The process is supported by artificial intelligence (AI) that utilizes sensors in order to continuously monitor the environment and adapt accordingly.

Food spoilage sensors: The sensors can detect gases and toxins which are found within spoiled meat or fruits and vegetables. This allows the user to know if their product is safe to eat just by using their smartphone, leading to less food waste.

Meal canteen app: This French app allows customers to pre book their meal choices at restaurants and schools. The purpose of this is to cut down on food waste,preventing keeping food out of storage or over cooking.

Sustainably produced sweeteners: A Canadian food technology company turns farm waste into sustainably produced sweeteners and nutritional supplements by using leaves and stalks leftover from traditional harvests into a variety of biomaterials.

3D-printed synthetic meat: The use of the 3D printer creates a texture which is similar to meat. To print around 100g of this synthetic meat costs under 3 dollars. This new creation could reduce the industry’s carbon footprint.
