Differenze Sostanziali:
La camera unica a cilindro rotante permette un’alimentazione ed un processo a ciclo continuo. Questo in quanto nella seconda fase del processo, si genera una fase termofila che resta perennemente attiva e garantisce con facilità il raggiungimento della temperatura di almeno 55°C che è quella minima richiesta dalla normativa per garantire la “Sterilizzazione” del materiale organico in trattamento.
The slow, gradual, and continuous movement of the material, through the rotation of the composting chamber, ensures that the thermophilic phase remains constantly active and that the material added daily enters a phase that is already thermally active
Questo aspetto è molto importante al fine di garantire le quantità di organico da poterconferire e trattare.
Multi-chamber composters, with two or more chambers, must operate with a discontinuous process flow. e superi la tempistica prevista dalla normativa, quindi attendere i tempi per arrivare almeno adì una temperatura di 55°C e poi far permanere il materiale a questa temperatura per almeno 72 ore. Solo dopo questa fase il materiale meccanicamente potrà essere spostato dalla prima camera a quella successiva dove subirà la fase mesofila. Ovviamente nella seconda camera deve permanere il tempo minimo previsto per legge non inferiore ai 30 giorni e questo fa si che in questo periodo la seconda camera non potrebbe essere caricata con nuovo rifiuto, impedendo il così definito flusso continuo. Queste macchine inoltre necessitano periodicamente (ogni 15 giorni circa) di una manutenzione ordinaria che prevede l’apertura degli sportelli della macchina per liberare i bracci interni dalle eventuali buste in mater B che si avvolgono intorno all’asse dei bracci rallentandone la movimentazione fino a bloccarli. Tale attività da effettuarsi a macchina carica rileva una criticità per quanto concerne le norme di sicurezza igienico sanitaria in quanto all’interno delle camere vi è il rifiuto in processo attivo con decomposizione e quindi vapori e odori indotti dal processo stesso.
Regarding the total process time, it’s important to note that, since the first chamber is loaded daily and a period of 20–30 days must pass before the material can be moved mechanically to the second chamber, not all material placed in the first chamber will undergo the same initial maturation time. Only the first material placed in the chamber will complete the full maturation period, while the later material will have a shorter residence time, which reduces the actual treatment capacity relative to the declared processing time.

Type of advancement
Camera unica:
Continuous
Altre Tecnologie:
Intermittent
Differenze Sostanziali:
In our single-chamber rotating cylinder plant, the material progresses continuously and automatically, as the newly added waste (which is heavier) pushes forward the lighter material that has already completed the thermophilic phase and is ready to be transferred to the subsequent mesophilic phase, from where it will automatically exit. The entire process, which is automatically stabilized at the required temperatures, reduces the weight of the organic fraction by an average of 80%.
In the multi-chamber system, the waste remains in the first chamber for a certain number of days, where it undergoes the thermophilic process. It then must be mechanically transferred to the second chamber, where it completes its secondary phase before exiting automatically or through manual unloading. In this type of machine, the waste is moved and advanced by arms supported by a shaft, which rotates to move the waste forward.
The shaft and arms inside the composting chambers can potentially suffer mechanical failures, which could lead to machine downtime for their replacement and/or repair. Additionally, the transfer of material from the first to the second chamber effectively resets the thermophilic process, requiring the process to restart from its initial low-temperature phase with each load. This dynamic means that, on many occasions, the biological process, including the initiation of the thermophilic phase, takes longer and faces difficulties in reaching the temperature required for sterilization, which, as per regulations, must be at least 55°C and maintained for at least 72 hours. This is also mandatory to ensure the sanitary safety of the mixed composted amendment (COMPOST) produced.
IMPORTANT: In the event of mechanical arm failure, the composter will need to be emptied for their replacement using a vacuum truck, which would incur additional costs and pose safety concerns.

Differenze Sostanziali:
In the single chamber, the complete absence of any mechanical components inside, combined with the loading point positioned at the top of the chamber, allows for loading the chamber to 75-80% of its volumetric capacity.
In multi-chamber composters equipped with internal shafts and/or arms and/or augers for movement, the loading capacity is usually limited to no more than 50% to avoid overloading the moving arms beyond their breaking point.

This system ensures the perfect composting process even when external temperatures are below freezing.
FAKE
WATERTIGHT COMPOSTERS
FALSE The term "WATERTIGHT" is misleading because composters have inspection doors, a screw for inserting waste, and other mechanical parts that make it IMPOSSIBLE to achieve true watertightness. For composters, the correct term is "LIQUID CONTAINMENT" of the process, considering that it is not possible to create a completely airtight seal for the entire composter.
INDUSTRIALIZED AND MAINTENANCE-FREE INTERNAL WASTE HANDLING ARMS.
FALSEIn fact, it is sufficient to request a user and maintenance manual to check what can be inserted and what is not recommended, in order to verify the actual criticality of composters with internal mechanical arms. It should also be noted that requiring (as some composters do, under penalty of warranty expiration) the manual removal of bags from the composter's arms every 15/30 days is practically impossible from both a hygiene and safety standpoint, as there will always be organic waste undergoing fermentation inside. This activity certainly cannot be included in a standard operating manual for the management of the composter itself.
COMPOSTERS WITH ARMS ARE MORE RELIABLE THAN SINGLE-CHAMBER COMPOSTERS WITH A ROTATING CYLINDER WITHOUT MECHANICAL ARMS
FALSE Since single-chamber composters with a rotating cylinder and without mechanical arms have fewer motors and no internal mechanical parts within the waste, they actually create greater reliability and, consequently, fewer mechanical parts to maintain. We would like to emphasize that no composter we have sold has ever been removed due to malfunction, and no composter we have delivered has ever failed an inspection. This, however, has already happened to some companies that sell composters with internal mechanical arms.
COMPOSTERS WITH MECHANICAL ARMS CONSUME LESS ELECTRICITY COMPARED TO SINGLE-ROTATING CYLINDER COMPOSTERS WITHOUT MECHANICAL ARMS
FALSE Composters with mechanical arms consume approximately 400% more electricity than rotating drum composters without mechanical handling arms. To clarify further, the typical energy consumption is generated by: a motor that introduces heated air from a resistance heater, a motor for the screw that feeds in the waste, a motor for the mechanical movement arms in the first chamber, a motor for the screw that transports the organic waste from the first to the second composting chamber, another motor that operates the arms in the second chamber, a motor for the biofilter that creates the negative pressure in the composter, and finally a motor that extracts the processed waste from the second chamber to the outside. CONSIDER HOW MANY ISSUES A COMPOSTER BUILT THIS WAY HAS AND HOW MUCH ELECTRICITY IT REQUIRES. IN CONTRAST, our single-chamber rotating bio-composters WITHOUT INTERNAL MECHANICAL PARTS are equipped with: a motor for the screw that loads the waste, a motor for the rotation of the composting chamber, a motor for the biofilter that creates the negative pressure in the composting chamber, and a motor that introduces air from a resistance heater for process stabilization.
SINGLE-CHAMBER ROTATING COMPOSTERS WITHOUT INTERNAL MECHANICAL ARMS HAVE LIQUID COLLECTION BASINS, AS THEY ARE NOT AIR-TIGHT
FALSE We highlight that the stainless steel basins are included solely for safety reasons related to maintenance. This is because, during maintenance of the input screw or the "nose" (the compost output side), material could fall during the process of detachment from the internal part of the composter, both on the intake side and the compost exit side

| DESCRIPTION | SINGLE ROOM | OTHER TECHNOLOGIES | SUBSTANTIAL DIFFERENCES |
| Process type | Aerobic | Aerobic | None |
| Type of room | Single chamber with a rotating cylinder without internal mechanical components | Multi-chamber with internal arms for the movement of the organic matrix |
The single chamber with a rotating cylinder allows for continuous feeding and processing. This is because, in the second phase of the process, a thermophilic phase is generated that remains permanently active and easily ensures the achievement of a temperature of at least 55°C, which is the minimum required by regulations to guarantee the "Sterilization" of the organic material being processed. The slow, gradual, and continuous movement of the material, through the rotation of the composting chamber, ensures that the thermophilic phase remains constantly active and that the material added daily enters a phase that is already thermally active This aspect is crucial to ensure the quantities of organic material that can be delivered and processed. Multi-chamber composters, with two or more chambers, must operate with a discontinuous process flow. Once the first chamber is loaded, it is necessary to wait for the material inside to activate the thermophilic phase and meet the required timeframes according to regulations. This means waiting for the temperature to reach at least 55°C and maintaining this temperature for at least 72 hours. Only after this phase can the material be mechanically moved from the first chamber to the next, where it will undergo the mesophilic phase. In the second chamber, the material must remain for the minimum time required by law , not less than 30 days, which means that during this time, the second chamber cannot be loaded with new waste, thus preventing a continuous flow. Additionally, these machines require periodic (approximately every 15 days) routine maintenance, which involves opening the machine's panels to remove any bags in material B that may wrap around the arms, slowing down their movement or even causing blockages. This activity, performed with the machine still loaded, raises a safety concern as the chambers contain active, decomposing waste, which produces vapors and odors from the process. |
