At Plant-e we regularly get all kinds of questions. Of course we want to answer you as quickly and as well as possible, but because of the crowds it can sometimes take a bit longer. For this reason we have written a handy FAQ, in which the most common questions and answers are mentioned.

So before you ask the question to us, you can quickly and easily find the answer yourself. Very handy.

General questions

What is the target group?

Plant-e is aimed at everyone who is interested in green energy, innovation and likes to experiment with new technology.

What do we offer at this moment?

For all products that you can purchase, see the webshop. For the products we are developing you can go to the technology page and the news overview.

What are the preconditions for the technology?

The most important preconditions for our technology are that it is used in an environment with sufficient water and sufficient plants. We are currently creating this environment ourselves by applying the technology to containers in which the plants grow. Plant-e is currently developing a system that can be applied in existing, wet nature areas such as delta areas, flood plains, rice fields, mangroves, etc. This means that this system can be applied in areas with both fresh and salt water.

What kind of material is used for the anode and cathode?

The material we use for the anode and cathode is carbon material. To make a circuit, we use titanium wire as a current collector. These materials do not contribute to the generation of electricity and are only used to conduct the electrons.

What kind of membrane do we use?

We use non-conductive synthetic separation material as a membrane.

Can the Plant-e system be combined with a water treatment plant?

The Plant-e technology can (in the future) be combined with a water treatment plant based on plants. By applying our technology (in the form of the system that we still are developing) close to the roots of these plants, electricity can be produced while the water is treated by the combination of plants and technology.

I would like to visit a presentation on location / at the Plant-e office, is this possible?

It is possible to take a presentation on location, for a presentation by a C-level employee we ask 3000 euros per half day. For the other members of the team, the rate is 500 euros per half-day. all this is excluding travel and (possible) accommodation costs.

It is also possible to book a presentation with a tour at the Plant-e office, the same rates apply as mentioned above.

Can the Plant-e system be combined with aquaponics or hydroponics?

It is currently not possible to combine our technology with aqua or hydroponics. In the future, research may focus on this, but at the moment this is not part of our activities.

Modular system

How much power does a system provide?

The power production of our modular system is sufficient to keep the application running, small flashing LED lights.

When does a system provide power?

The plants will generate electricity day and night as long as the system has enough water. In the case of frost, the production of electricity temporarily stops. If the soil defrosts, the system will start up and produce electricity again.

What does the maintenance of a system look like?

A small system is easy to maintain by giving enough water and (if desired) pruning it. We offer maintenance contracts for the maintenance of large systems. These are aimed at both green and technical maintenance. For more information about the possibilities, send an email to office@plant-e.com.

What is the life span of a system?

The life of the product depends on the materials. The materials used by us are inert and will therefore not perish (they themselves do not wear down in the process of electricity production). The most vulnerable are the electrical circuits in the products, but these components are easily replaced by the accessibility of the electronics.

Which plant species are used for the system?

In principle, all plants that can withstand "wet feet" can be used. The technology works in a water-saturated environment, which means that the roots of the plants are also under water.

We often use grasses, because grasses can withstand water well and make an extensive root system.

For suitable plants, go to our plant list you can find here. This list is not exhaustive, so if you think that plants are missing we would like to hear this.

Is it possible to process the technology in a different design?

The system that we can offer at the moment consists of modules (bins) of 100x40cm. The plants and technology are integrated in these modules, the wires will not be visible.

Students / Students

I would like to do research on Plant-e technology (P-MFC) for my study or school, where can I find more information about this?

You can read more (scientific) information about the P-MFC the thesis of Marjolein Helder.

For help with profile workpieces you can contact with the sub-department Environmental Technology from Wageningen University.

Can I do an internship at Plant-e?

Plant-e offers internships. Send an email to office@plant-e.com with your resume and a letter of motivation in which you clearly explain your background, the duration of your internship and what you would like to do at Plant-e. We will then see if we have opportunities to offer you an internship.

Before you send an email to apply for an internship you must know that:

  • We ask that you have hair available for at least 4 months.
  • You have to find a room yourself if you want to come and live in Wageningen during your internship.
