FERTIGATION

fertigation s. f. [comp. of fert(ile) and irrigation]. – In agricultural practice, fertilizer irrigation done with water in which natural organic fertilizers or chemical fertilizers in appropriate concentrations are dissolved. [Treccani vocabulary]

Modern irrigation systems are complete systems made up of all the components suitable for conveying irrigation water, coming from artesian wells or other sources to the crops or plantations for which they are intended. These systems also include field sensors, control valves, fertilizer product dispensers, weather detection station and in general all the accessories necessary for their operation, including Apps from which it is possible to manage and monitor all activities of irrigation.

Thanks to its proprietary technology, REIMEX Group is able to add the self-production of the fertilizer product to all these functions. In fact, our fertigators are integrated with photobioreactors that produce biofertilizer or biostimulant from the direct cultivation of microalgae or cyanobacteria.

With REIMEX fertigation systems, a company has the possibility not only of managing irrigation according to the most modern criteria of rationalization of water resources and optimization of spraying times and methods, but of producing its own biofertilizer, customizing it on its needs and saving on the purchase of product from the market.

MICORALGAE CULTIVATION

coltivazione-microalghe-reimex

For some years, algae have been the subject of studies and research regarding their benefits in both human and animal nutrition for various reasons: their richness in proteins and their easy availability and cultivation compared to other plant species.

An essential step to increase the production and diffusion of algae, also often referred to as microalgae or cyanobacteria, is the possibility of cultivating them in limited, open or closed environments, despite their original habitat being fresh or salty open waters.

In particular, the cultivation of algae in closed aquaculture systems called photobioreactors, which allow particularly efficient growth yields, is proving to be very effective.

Thanks to the protection from pollutants, negative atmospheric events and the optimal regulation of the chemical-physical conditions of the “aqueous soil” for cultivation guaranteed by the use of photobioreactors, the cultivation of algae stands out as a sustainable and profitable solution for operators in the agricultural and livestock sectors who decide to combine this activity with their main one.

As living organism, microalgae require physical and chemical contributions to grow and develop. Speaking of physical stimuli, these are temperature and light. As with our organism, in fact, algae have their own level of well-being, where vital functions are maintained optimally. Chemical stimuli are instead represented by nutrients, such as CO2 and chemical compounds of various nature based on phosphorus, nitrogen, etc.

REIMEX Group’s photobioreactor technology guarantees the control of all these parameters, making possible optimal yield and quality of microalgae growth.

Unlike the technologies available today, the REIMEX Group photobioreactors automatically manage all the phases and parameters of growth on an industrial scale, with methods that today are only partially applied and only in laboratory devices, such as, but not limited to: the nutrient injection points, the CO2 supply, the lighting cycle, the cleaning of the process pipes between one cycle and another, etc.

The REIMEX Group photobioreactors are set up in standard 6- or 12-meter containers, designed with a modular criterion that allows the production of microalgae starting from approximately 400 kg onwards of dry product per year, quick to be started in very limited spaces and without excessive bureaucracy.

A further exclusive operational advantage of the REIMEX Group photobioreactors is the possibility of being able to manage the two lines of which each unit is made up independently, thus being able to diversify different algae type strains and limiting the risks of possible production losses in the event of critical issues with one or the other culture.

ENERGY PRODUCTION

For many years the agricultural world has been familiar with the so-called biogas cogeneration plants. These plants use sewage and plant residues to produce a fermentation gas which is then used in internal combustion engines to generate electricity and heat.

Biogas systems are indeed rather invasive for agricultural companies, occupying large areas, in addition to the spaces used and complications related to the management of the sewage collection tanks. Their management and maintenance is also onerous and stringent due to their intrinsic technical characteristics and the handling of biomass that is not exactly “clean”.

Furthermore, biogas plants require rather large quantities of liquid or solid biomass to operate and the operative time and procedures are subject to the process of fermentation and generation of biogas.

REIMEX Group has developed a proprietary hybrid system concept that allows the use of even minimal quantities of agricultural residues, and the purification and recovery of wastewater, using the residual solid part for the generation of energy and heat.

The operational flexibility of REIMEX Group cogeneration plants allows energy to be produced at the most convenient times and quantities, both for self-consumption and for export.

REIMEX Group’s energy and heat production systems are set up in standard 6- or 12-meter containers, designed with a modular criterion that allows production starting from few kW onward, quick to be started in very limited spaces and without excessive bureaucracy.
