Agriculture: Sustainable Agriculture through Film Farming

Mebiol Inc.

Growing Vegetables with Less Water 


ebiol, Inc. has invented a film called “Imec” made of hydrogel for growing vegetables with less water. Using this method, agriculture can be done virtually anywhere -- even on desert land or concrete. The film prevents harmful viruses and germs from getting in, rendering pesticides unnecessary. The film also creates a “water stress” that helps crops such as tomatoes synthesize large amounts of sugar, amino acids, and other nutrients. This, in turn, leads to more natural sweetness and higher nutritional value. In addition, Imec eliminates soil contamination that can negatively impact crop productivity and quality.

Imec was invented by Dr. Yuichi Mori, CEO. He did so after 30 years of developing membranes and hydrogel technologies that are utilized in dialysis membranes, catheters, artificial blood vessels, and other forms of medical equipment. He wanted this invention to stabilize food supplies and address safety issues created by water shortages and soil contamination as a result of global warming.

At its core, Imec film encourages plants to make a large number of capillary roots so as to more efficiently take in nutrients.

Major Features and Advantages

I. Reduces Water Consumption
Imec reduces water consumption to less than a quarter of what is needed for hydroponic farming, and 1/10 of conventional farming using soil. The sugar content in Imec tomatoes, for example, is nearly twice that of hydroponic tomatoes.

II. Use in Barren Areas
Imec can produce results even in barren areas that lack agriculture, such as areas of Japan that have been devastated by tsunamis. It can even be used in the soil-contaminated suburbs of Shanghai or in hot and unforgiving Dubai deserts.

III. Easy to check the roots of plants
Because capillary roots are so crucial for healthy plants, they need to be at their best to yield quality crops. With Imec, it is easy for anyone to check the density and color of roots. This offers a better way to diagnose any potential problems that may exist in crops like tomatoes.

Technology Data

Conceivable Applications

We invented a film made of hydro-gel for growing vegetables with less water. This method (called Imec) allows for agriculture anywhere, even on desert land or concrete. Since the film blocks harmful viruses and germs, pesticides are unnecessary. Better yet, the “water stress” the film creates induces crops like tomatoes to synthesize large amounts of sugar, amino acids, and other beneficial nutrients, leading to greater sweetness and higher nutritional value. Imec also eliminates the soil contamination that affects the productivity and the quality of crops.

Competitive Advantage

Using Imec reduces water consumption to less than a quarter of hydroponic farming. The sugar content in Imec tomatoes is almost twice as much as that of hydroponic tomatoes. Imec “makes visible” the condition of roots that could not be seen with conventional agricultural technologies. A very large number of capillary roots grow when using Imec. Capillary roots are highly important organs for plants, and they affect the health of crops, influencing both yield and quality. Seeing the amount of roots and their color and the amount of water and nutrients absorbed is an effective way to understand the condition of the tomatoes and diagnose any potential problems. By using Imec film—a uniform industrial product—instead of soil, even inexperienced individuals can learn reproducible agriculture in a short period of time.


Using Imec reduces water consumption to less than a quarter of hydroponic farming. The sugar content in Imec tomatoes is almost twice as much as that of hydroponic tomatoes.

Technical maturity

Imec was introduced for the first time in Japan in 2008. The diffusion area now has reached over 330,000㎡and is still expanding. Taking advantage of the characteristic of Imec that can produce high-quality crops even barren areas without agriculture, people are starting to produce high-quality tomatoes in the devastated areas by Tsunami in Japan, in the suburbs of Shanghai where the soil contamination is concerned, and in the Dubai desert areas.

Farmers are conservative to adopt new technologies. More than 60% of our customer base comes from manufacturing and other non-agricultural industries.

Schematic illustration of the technology

Imec (film farming) is the world’s first agricultural technology developed to cope with stable food supplies, produce quality assurance, water shortages, soil degradation, pollution, and other serious issues that the world is facing today. Imec is a technology for cultivating plants on a special film, called a hydrogel membrane, placed over a nutrient solution. This film has countless nano-sized holes blocking bacteria and viruses, drastically reducing the use of pesticides and producing safe crops even when the nutrient solution gets contaminated. Imec also eliminates the loss of water and fertilizer.

Due to the nature of the hydrogel, the nutrient solution absorbed into the film does not come out even if the film is squeezed. The crop produces an enormous number of capillary roots to ingest the nutrient solution in the film. However, since this root system is still insufficient to ingest all the available nutrients, the plant synthesizes a large quantity of sugar and other products to raise its intracellular osmotic pressure. The resulting osmolality gap allows the plant to transfer the culture medium from the hydromembrane, leading to high nutritional content due to water stress. Imec is an innovative farming technology that maximizes the latent potential of crops.

Mebiol is also developing a new plant factory technology aimed at cultivating leaf vegetables like lettuce using Imec film.


Soil is the main factor for agricultural produce, but it is very difficult to accurately control its nature because it depends on the place and season. It is said that making the proper soil and acquiring the watering techniques needed for the stable production of high-quality tomatoes (known as fruit tomatoes) can take ten years. By using Imec film—a uniform industrial product—instead of soil, even inexperienced individuals can learn reproducible agriculture in a short period of time.

With Imec, farmers can produce high-quality vegetables even in deserts, areas with contaminated or salt-damaged soil, and inside buildings. The Imec film is completely isolated from the ground by waterproof sheet, so it is not affected by the soil. At the same time, since the supplied water and fertilizer do not leak, the amount of water and fertilizer used is much less than in conventional farming methods. This is a very environmentally friendly farming method. Currently, farmers are implementing Imec farming in the deserts of United Arab Emirates (UAE) and in areas with the pollution risks in China. We shall be very pleased if Imec were to help to create employment in areas unsuitable for agriculture, help their economies recover, and help their people regain hope.
