Definitions
- the present invention is part of the field of paper waste treatment industry, as well as in the livestock sector.
- the present invention relates to a paper waste treatment process characterized by having stages of dehydration of the waste by subjecting it to high temperatures.
- the present invention also relates to the product obtained by the dehydration process of paper waste having a high hygienic quality, free of bacteria and other pathogens.
- the present invention also relates to the use of the material obtained by the paper dehydration treatment in the manufacture of beds or beds for cattle.
- Paper mills generate various types of waste “garbage, sand and sludge” that normally appear in the recycling process.
- the so-called “arenas” are produced by subjecting the paper to several recycling phases, specifically about 4 or 5 times, the amount of "sand” produced may vary according to the quality of the paper or even by the type and machinery used for In the aforementioned process, the percentage of waste generated does not usually exceed 15% of recycled paper or cardboard.
- the characteristics of the residue are a high percentage of humidity, spongy texture, a light brown color and an appearance of water-soaked granulated cardboard, these characteristics do not share similarity with any other residue, neither for its texture nor for its composition.
- patent EP 0796230 whose title is: method for the preparation of a pozzolanic material from paper waste and method for the manufacture of cement from said material, which refers to a method for conversion thermal of a material containing kaolin in a material of pozzolanic characteristics, in which the material containing kaolin is heat treated at elevated temperatures in a fluidized bed installation having a free base in the presence of oxygen-containing gas and characterized in that the material containing kaolin consists of waste paper or waste from recycled waste paper for reuse in the papermaking industry.
- the present invention provides a useful and simple solution to the waste management problem of the paper industry, by means of an effective and rapid recovery process of the cellulose present in the paper waste that allows The product finally obtained has a series of characteristics that allow its use in the livestock industry, for the manufacture of beds or beds for cattle.
- one of the objectives of the present invention is to achieve a useful purpose for the waste produced by paper mills, as an alternative to the use of waste produced by them, thus reducing environmental pollution of factories and reducing production costs.
- the present invention relates to a process for treating waste that comes from the paper for the recovery of the cellulose present therein.
- the present invention also refers to the product obtained after the waste treatment procedure, which is a simple and useful solution to the waste management problem of the paper industry, thus complying with the technical-sanitary and environmental management training of this type of waste.
- Another objective of the present invention is the use of the recovered cellulose by means of the process previously mentioned in the livestock industry, for the manufacture of beds or beds for cattle.
- the main objective of the invention is to achieve a highly hygienic and absorbent product as a bed for animal use in livestock farms not known until now for that purpose. Developing new waste recovery formulas which so far lack utility and their only profitable exit is that of the landfill. For this, it is necessary to carry out a paper waste treatment, in order to obtain a product with a high cellulosic content of a hygienic level that allows its use in the livestock sector.
- the transformation process is based on a dehydration of the residue preferably by means of a horizontal drying plant at low temperature, (it is necessary to mention that these machine-plants already exist but are not used for this purpose, so it would not be obvious for A person skilled in the art will use this type of systems for sludge or sand of the paper), or before advancing to the passage through this plant, the passage by rollers to eliminate the first percentage of water (achieving an energy saving), or optionally drying natural to the sun, among other possible that may occur.
- the main qualities are those of a greater absorption of urine, excrement and bad odors, being much more hygienic than the other products destined to these functions.
- the products that are currently used are straw, shavings or even earth, these being not very suitable for this utility since they are more susceptible to Generate bacteria and fungi, among other types of pathogens and therefore move away from complying with the Health Regulations.
- the waste referred to in the present invention is generated in the process of recycling paper and cardboard, in this process several types of non-toxic waste are generated such as garbage and sludge, the latter are those resulting from subjecting Continuous paper recycling processes.
- garbage and sludge the latter are those resulting from subjecting Continuous paper recycling processes.
- the percentage of rejected cellulose does not exceed 15% of the recovered paper.
- the grinding process will pass to the horizontal dryer at a temperature between 7O 0 C and 90 0 C and a time between 4 and 6 minutes; In this way we will ensure that any existing virus or bacteria is eliminated.
- the resulting product will have a humidity of less than 15%, preferably between 0 and 10% humidity, then it is packaged in different formats for later use.
- Our product is characterized by containing between 25 and 35% of cellulose, between 45 and 60% of water, between 20 and 30% of calcium carbonate, presenting a pH between 6.8 and 7.4 and a carbon / nitrogen ratio of 35/45.
- PE TOXICITY ANALYSIS This analysis was negative, so it is declared as a non-toxic product.
- the invention relates to a process for recovering cellulose from paper waste comprising the steps of:
- the resulting product After going through the last drying process the resulting product will have a humidity of less than 15%, preferably between 0 and 10% humidity, and absent of pathogens, thus obtaining a dehydrated product that is characterized by containing between 25 and 35 % of cellulose, between 20 and 30% of calcium carbonate, have a pH between 6.8 and 7.4 and a carbon / nitrogen ratio of 35/45.
- Another important aspect of the invention relates to the process for the recovery of cellulose from paper waste in which a stage prior to step a) is additionally carried out, passing through rollers to remove the first percentage of water.
- Another important aspect of the invention relates to the process for the recovery of cellulose from paper waste in which a stage prior to step a), of natural drying in the sun to eliminate the first percentage of water, is additionally performed.
- a second important aspect of the invention relates to a dry cellulosic extract obtained by the process described above which has the following parameters in the final dehydrated residue:
- the product before drying is characterized by containing the following percentages of the following elements:
- Carbon / Nitrogen Ratio 35/45 Another important aspect of the invention relates to the dry cellulosic extract obtained by the aforementioned process in which the higher calorific value increases after the process between 100% and 200%.
- Another important aspect of the invention relates to cellulose recovered by the method described above in which the final residue is free of the pathogens selected from the group consisting of:
- a third important aspect of the present invention is the use of dry cellulosic waste for the manufacture of beds or beds for cattle that has the characteristic of a high degree of absorption of liquids and odors and that once finished its function as an animal bed will present some qualities such as exceptional organic fertilizer, which are in turn beneficial for the environment and cease to be an important problem.
