BIOZIMMI combines the gasifiers’ cost-effectiveness with the disposal total efficiency of a plasma torch.
Our gasifiers have been developed in collaboration with the RINA Consulting - Centro Sviluppo Materiali spa, a subsidiary of RINA Group. Within the plasma torch we apply an American-made hybrid electrodes that have been used for over 50 years to dispose of urban MSW everywhere in the world.
Sustainable and successful treatment of MSW must be safe, effective, and environmentally friendly. BIOZIMMI was thought to solve the two main drawbacks of traditional landfills: surrounding areas of are often heavily polluted since it is difficult to keep dangerous chemicals from leaching out into the surrounding land and that any landfill can increase chances of global warming by releasing CH4, which is 20 times more dangerous as a greenhouse gas than CO2. Therefore, we find a more environmentally friendly alternative to treat MSW.
The gasifiers take advantage of the molecular dissociation, called pyrolysis, used to directly convert the organic materials present in the waste into gas, by heating, in the presence of small quantities of oxygen.
The processed materials are completely destroyed because their molecules are dissociated. The synthesis gas, even when of a low calorific value, once filtered and purified, can be used for the feeding of a cogenerator, thus enhancing the calorific value of the organic matrix used and can be contain costs simultaneously producing electrical and thermal energy, or it can be used for the production of reusable chemicals.
Moreover, it is possible to get practically pure water, thermal energy and methanol.
Our system is modular and consists, inside of each gasifier, of 3 reactors that can be operated individually or in unison. This is therefore an extremely flexible system, capable of treating different matrices simultaneously, modular and can be implemented, as needed, with further ancillary systems, able to maximize the efficiency of energy recovery.
Our gasification system involves the use of drying systems for pre-treating the incoming material or matrix. The dryer is fed through the process’ heat and allows to bring the input humidity of the matrix by the value of the conferral (normally value between 70% and 30%) to, approximately, 10%.
The matrix is dried in this way, is transported inside the reactor, where it is raised to temperatures ranging from 400 to 650 ° C, through the recovery of heat generated by the same syngas and by the same process of gasification that happens in the last part of the reactor. The waste is so subjected, quickly, to the total drying, pyrolysis and gasification.
The produced gas (syngas) are sent, after being washed and purified, to a turbine and / or to an endothermic engines. From their use, will be produced thermal KWs and electrical KWs or methanol. Part of the electricity will be used for self support the process (about 15%), the other will be used to reduce the costs of other energy-intensive processes within the plant or entered into the national network, if possible. The heat can be used locally for the drying or by creating a district heating network to create cold thanks to the inverters.
Once the gasification process has taken place, the only resulting waste product is ash, on average about 5-10% of the matrix entering the gasifiers. The part of the ash treated in the plasma torch will turn into a material that can be used for useful purposes without environmental risks.
The ash can be analyzed to assess its capacity for amending or usability as a building material.
In RINA Consulting - Centro Sviluppo Materiali spa, there is a pilot that can be visited, fully equipped with a plasma torch.
