Ed van der Post Thanks..I know this project. But Aquaponics is a little bit different

Human Urine in Hydroponics

It is possible.! Use human urine safely, get clean water and at the same time grow food, all in one step! Why? Because the daily amount of urine per person per day is good for almost 3 kg of lettuce.

We see that water scarcity and water pollution are increasingly causing serious health and environmental challenges throughout the world. An important reason is that a good infrastructure is often absent to discharge the waste water responsibly. There is too little circular thought about water. The future wastewater infrastructure should therefore be seen more as a combined recycling plant & wastewater treatment plan, and depending on local needs and constraints. Some regions are faced with water stress and groundwater depletion because of climate changes, population growth, and the frequent occurrence of drought (low rainfall). A first step could be that we collect domestic waste water in a special system and separate toilet waste. Gray water comes from

Wim Goris Hi Edwin, thanks for sharing this detailed article on circularity for nutrients.  I was at the Dutch Design week, but missed the peeponics. Are you aware of the all the work that APF members Hivos and SNV do on biogas. See for example : https://agriprofocus.com/post/5767b54ea93f2543ab06f8f9

Ed van der Post Hi Wim, not quite. But when it comes to methane, I find it interesting. Gas from vegetable residual waste. Other gasproducts....I don't now. Especially when methane gas can be linked to hydroponics I am in favor or solar energy

The nitrate hazard and the role of hydroponics

Why do we accept that the nitrate content is constantly increasing in our food, and is this a healthy development? The answer is clear. No, and I will try to explain the reason.

In het Nederlands http://hydroponics-nederland.nl/nitraatgevaar-en-rol-hydroponics/

Nitrate occurs in minerals, soil, groundwater and the atmosphere. The general view is that nitrate is not harmful. Although we know that the body converts nitrate into nitrite and nitrite can cause health problems. The general view is also the legitimate reason why growers use this easily, because the nitrogen in nitrate helps plants to grow. Plants naturally extract nitrate from the soil, but it is also a common and widely used ingredient in fertilizers. In addition, factors such as light, temperature and season also play a role in the amount of nitrate that eventually ends up in crops. For example, the amount of nitrate in vegetables such as lettuce is seasonal. In winter it is about

Container farming is the cultivation of products in a container, which is adapted in such a way that the weather conditions are overcome and fully is equipped with the most efficient hydroponics cultivation system possible. Container farming is hot. The superlatives will fly you over if you look for them. But is that right? Here is a critical view of this new way of vegetable growing.

The question we have to ask is whether the rise of container farming is a realistic technological development or only suitable for an exclusive crop of lettuce. It is time to puncture unrealistic expectations and to talk honestly about the possible advantages and disadvantages of this trend. I hope that through this article, which has arisen after research of the various sites, the exchange of experiences with people in various countries and stories that I have heard from all over the world, wich I will give you an as objective as possible picture of the real place that container farming could take in the fut
