Exactly two years and a day after the disastrous fire in BlueCity, rotterzwam opens its new oyster mushroom farm on May 24th, 2019. With a crowdfunding, the circular company raised almost € 400,000 last year. In the new farm, rotterzwam will convert 7,000 kilos of coffee grounds into oyster mushrooms for citizens of Rotterdam and the hospitality industry every month. Alderman Arno Bonte of Sustainability opens the farm.

The farm, located at Schiemond in Rotterdam-West, consists of old containers that have been converted into growing units. The concept is modular, mobile and scalable. As a result, rotterzwam gives a boost to the circular economy in the Netherlands with this new farming concept.

Urban environment
The growing units contain a modular and sustainable climate system, which is fully optimized for mushroom cultivation. These units, which are especially suitable for an urban environment, are a place where local residual flows can be converted into food.

CO2 negative
There are 152 solar panels on the roof of the farm that are expected to provide the full energy requirement. This means that the farm will become energy neutral. But rotterzwam would not be rotterzwam if it doesn't go a step further. Siemen Cox: "The processed substrate that remains after the growth process of the oyster mushrooms is returned to the soil. As a result, we expect to be CO2 negative within the next two years." The organization fixes more CO2 in the soil than the total business process emits.

The new rotterzwam mushroom farm is unique. This is because it is the largest mushroom farm in Europe, which grows mushrooms on self-made substrate from local coffee grounds, and will also be energy neutral and CO2 negative.

Worldwide
Mark Slegers explains: "It is our dream that every city in the world has a mushroom farm that converts the many coffee grounds from that city into oyster mushrooms. The modular farming concept can therefore also be purchased from us. To support this vision, we have chosen partners who can help place these mobile mushroom units anywhere in the world. "

A sentence often heard in logistical companies but even more nowadays in mushroom growing.
Due to short schedules, labour management and supermarket requirements timing in the growing of mushrooms is essential.

If mushrooms are not in time one can loose part of a flush. The compost for the next room is ordered. Supermarkets need the mushrooms on the shelf on a set time and for the organisation of the picking force a strict timing is needed. Even if it is just to stay away from picking in the weekends to avoid high labour costs.

To ensure a right start of the first flush on the desired time many factors are involved.
The activity of the compost is one of them. An active compost or an inactive compost can easily make a difference of a few days in the start of the first flush. A corrective measure there can be supplementing. And for all the choice of supplement and the quantity. Especially in combination with the right type of casing soil this has great influence. No need to say that both compost and casing soil need to have a good stability. The combination of those two can be seen in the amount of caccing and the deepness of the casing layer.

Water on casing soil is the next determining factor. It is well known that water can stop the mycelium from growing. A factor that can be used to time flushes.
A very strong tool is the ruffling machine. By ruffling the grower can time flushes even more accurate. Generally ruffling is done between days 3 and 6 after casing the room. Later ruffling often also means a slower recovery because older mycelium has a slower re-start. Ruffling is done a lot by farms who have very strong time requirements by the supermarkets. A negative aspect of the ruffling can be that the staggering of the flushes is more difficult. But this can be overcome by changes in the climate setpoints during fructification.

So just looking at timing of crops, the grower has many options. Unfortunately this also means enough options to make mistakes but isn’t this what makes mushroom growing interesting?
