= SUW - SOLID URBAN WASTE/GARBAGE =
This document contains information on, and descriptions of, a patented and innovative industrial plant that can execute the complete reconversion of biologic mass to produce manufactured goods for civil, agricultural and industrial use. The process and its by-products are highly eco-friendly and are free of harmful liquid or volatile emissions. Electric and thermal energy is also produced as a by-product of the system. The biologic masses here expressly considered are the component parts from the urban waste collection.
All productions are achieved through the complete manufacture of heterogeneous masses of organic origin, and more specifically of solid urban waste, here considered as raw material.
The process is completely eco-friendly and can achieve the immediate “cold” transformation of mass, obtaining the base products, morphologically changed, separated, sanitized and non pathogenic. The purpose is to obtain, through subsequent treatments, manufactured goods for civil, agricultural and industrial use, as well as electric and thermal energies.
SHORT SYNTHESIS OF THE PRODUCTIVE PROCESS.
Upon reception of SUW, they are discharged into silo-hoppers, which are fully sealed and self-cleansing, that feed the process. The deterioration of the contents during the temporary stay in the silos can be delayed by the introduction of a nitrogen atmosphere into the silos. During the process, the contents are sucked up through the sanitary implementation of "srubbers."
Through a treatment effected by hyperbaric pressure without any introduction of heat, in adiabatic line, the waste is morphologically changed and transformed into two sanitized pathogen-free by-products, one of which is assigned to the production of manufactured goods, and the other one to a fertilizer. The full process is carried out in a closed circuit and the workers are never in contact with residues posing septic risk, since, earlier in the process, any kind of pathogen or other infesting/polluting germs are eliminated or neutralized.
CNRI/animal production of Reggio Emilia (Italy) and CNRF, University of Poitier (France) Heat Dept. have analyzed and verified the cleanliness of this product.
The substance that is headed for the fertilizer is obtained within approximately 50 minutes, ready for use, and free of pathogens and infectious seeds. This quick maturing process is can be achieved because, early in the process, the high pressure has broken the cocoon of the cells of contents and has extracted the relevant enzymes. The process has been estimated by Dr Bugherra, General Director of CNRT in Boris Cedria, Tunisia.
The following materials have been deemed acceptable by the plant:
• Solid Urban Waste
• Food Industry waste
• Breeding waste
• Spoiled or infected agricultural products
• Foliage and pruning waste
• Spoiled or infected by-products of the food industry
• Mud (previous analysis requested)
• Thermoplastic material waste
• Industrial by-products (previous analysis requested)
• Biological masses and others ( previous analysis requested)
The main obtainable productions are:
Ø * Base product for thermosetting resins
Ø Thermoplastic resin compounds and products
Ø Base products for varnish industry
Ø Product for the laying of road lining
Ø Scrap iron ready for foundry
Ø Metal scrap
From the first two products and with the adequate specific plants, it is possible to obtain, through a fermentation and pyrolysis process, gas, and from this, electric and thermal energy.
Experiments have been made with SUW originating from small towns having considerable industrial and agricultural activity, consequently yielding a vast range of waste for experimentation. The products deriving from the process were of top quality.
The unit capacity is modular; each module can treat some 100.000/120.000 tons/year. A part of the yearly output can be assigned to energy production, i.e.:
- 38.000/40.000 tons of organic fertilizer, for the fermentation
- 18.000/20.000 tons of wood and its by products for the pyrolysis process.
For the full exploitation of the products stated above, two different generating plants are needed, thus allowing the production of electric and thermal energy:
1) From the fermentation of fertilizer it is possible to obtain:
1.1. 25.000 electric MWhe/year with as much MWht of thermal energy generated by three 1200 KVA generating sets working 8000 hours/year
1.2. 22.000 mtons/year of residual utilized fertilizer, after deduction of the weight of methane gas produced.
2) From the pyrolysis it is possible to obtain:
2.1. 25.000 electric MWhe/year with a turbine and as much thermal energy are produced and utilized in the production processes
2.2. The ashes, as residue of pyrolysis, are the remaining 4% and are fully re-utilized in the production of fertilizer.
Gas emissions, monitored with EU parameters are of no consequence. It is well understood that the pyrolysis is fed by wood and its by-products.
The plants are also modular, and each module can treat 100.000/120.000 mtons/year and consequently considering the average production per head of SUW, and taking into account that the working period of a plant is of 365 days/year, the plant needs the production of some 330.000 inhabitants to assure its continuity.
From simple garbage collection, each plant produces the following, without any need of differentiated collection:
§ Fertilizer.
§ Manufactured goods.
§ Thermal and electric energy.
§ Any unusable inert aseptic residual waste, making up less than 2% of the whole treated mass, is destined to a garbage dump.
The said processes follow the conservation principles set out by one of the fathers of modern chemistry, namely A. Laurent De Lavoysier: the principles of conservation of mass and animal respiration.
It is quite suitable to draw the conclusions about the importance of this process from an environmental and economic point of view. This is the most important innovative aspect of such a patented process. The plants described above use some of the most advanced technologies in ecology to date. The waste collection is made incredibly easier and more economical.
The resultant manufactured goods and the invaluable possible variety of products, the high quality of the resultant organic fertilizer, and the resultant production of usable energy, are of great importance. Part of the energy produced, can be utilized to power the operation of the plant. Note, however, that this is a claim that the energy output is higher than the energy input--the principle of conservation of energy is still upheld, as the new energy is input from the incoming waste, and it is this energy that is efficiently used to continually power the process.
From an economic viewpoint, the running of this process becomes profitable with a medium term amortization. The running of the plant, foreseen in 8.000 hours/year, needs around 90 persons and its derived activities are considerable. The medium term amortization and the cost of the plant give a very high turnover for the final productions on which the Treasury can cash over $10.000.000,00/year. Our plants can be adapted to any climatic and environmental exigency and can be planned, built and operated worldwide.
Additionally, with reference to areas of heavy population density or important cities, with our exclusive technology it is possible to satisfy the request of disposal and processing with the following added result:
- The limited distance to be traveled of the garbage trucks
- The limited land area requirements
The said system, named by us “B Islands” gives us the possibility to operate in accordance with our statements. The final result is that waste turns to "heterogeneous mass" of the De Lavoysier industry which with the greatest respect of the environment, produces manufactured goods through ecologically integrated techniques while at the same time rapidly producing organic fertilizer via an eco-friendly process.
Some of the productions can be apt to feed two different plants for the ecological production of renewable energies.
