Circular Economy

The roughing and grinding operations vary depending on the type of waste on which the treatment is to be applied. It is also subject to the infrastructural conditions of the location and the overcrowding capacity that is available.
It is therefore essential, in order to offer a precise description of the required pretreatment phases, an inspection of the conditions in situ and the characteristics of the waste to be treated.
• Manual screening: a conveyor line will be established with sufficient length to be able to place a group of workers on its bands to remove any improper (plastic, metal, stone) present in the waste stream.
• First magnetic screening for ferrous materials. Magnetic screening or overbands will be implemented on the conveyor belt.
• Screening of non-ferrous metals. Through an Eddy Current system, also implemented on the conveyor belt, non-ferrous metal materials will be separated from the flow.
• Shredded. Once the previous processes have been carried out, the waste flow will be directed to a shredder. The type of crushing is very dependent on the type of majority waste to be treated, therefore a technical analysis of the waste flow would be pending.
• Second magnetic screening. Once the residue has been crushed, it will pass through another overband to eliminate the ferrous materials that could remain in the flow.
• Lastly, the waste stream will be transported to a trommel where a final mechanical separation will be carried out.


Once the waste has left the trommel, it is ready to go to the treatment or biocatalysis phase. Pretreatment can begin even before biocatalysis is implemented in the process. The resulting material that comes out of the Trommel can be stacked while waiting for the biocatalysis modules to be placed.

The application of the treatment technology finds its bottleneck in the pretreatment since the biocatalysis acts almost immediately to generate a high quality biostabilized product.
Sugarcane: the residue from the exploitation of sugarcane can also be treated, however, the physicochemical nature of said residue could require a more complex pretreatment system that would have to be specifically designed.


The result obtained after the biodegradation of the organic residue is a fertilizer material with high nutritional capacities comparable to humus.
Although the nature of the process is similar to that of traditional composting, the technical procedure is based on a completely different degradative paradigm that not only drastically reduces the treatment time but also improves the quality of the product obtained.
Regarding the productive performance, the amount of fertilizer obtained is equivalent to the weight of the amount treated with a positive or negative modifier that depends on the degree of humidity of the residue.
The fertilizer must come out with a specific amount of moisture. If the waste enters with more water than necessary, it will have to be removed from the resulting material and therefore the amount of fertilizer obtained will be less than the amount of treated waste.
If, on the contrary, the material enters too dry, it will be necessary to add water until it reaches the appropriate humidity conditions. In this case, the resulting material will have more weight than the waste to be treated.
