Definitions

  • the present invention relates to a process for recycling cigarette butts and the like, of the type pointed out in the preamble of the first claim.
  • the process is suitable for recycling the cigarette portion remaining at the end of a cigarette after use, which consists of the filter and an envelope and, in some cases, of a tobacco portion adapted to be removed before recycling.
  • Smoke from a cigarette introduces more than 4000 chemical substances having an irritating, noxious, toxic, mutagenic and cancerogenic action into the surrounding environment. In particular, these substances enter the smoker's respiratory system.
  • each cigarette is provided with a filter fastened to a cigarette end and adapted to at least partly retain the aforesaid chemical substances.
  • the filter is adapted to be placed at least partly inside the smoker's mouth so that smoke is forced to pass through the filter before reaching the smoker's lungs.
  • the decomposition time of a cigarette butt varies from one to eight years; in fact, in spite of the fact that tobacco and paper dissolve in few months, the filter resists the bacterium enzymes for several years.
  • Cigarette butts as pointed out by ENEA (A domestic agency for new technologies, energy and sustainable economic development) are classified as dangerous waste for the environment. In fact, a recent research of the United States has proved that butts are part of the main waste suffocating the Mediterranean sea.
  • the technical task underlying the present invention is to conceive a process for recycling cigarette butts and the like capable of substantially obviating the mentioned drawbacks.
  • the process for recycling cigarette butts and the like according to the invention is generally identified by reference numeral 100 .
  • Butts 1 as shown in Fig. 2 , include a filter 1a , which is employed for retaining at least part of the harmful substances produced by the cigarette, an envelope 1b usually made of paper material and adapted to surround the whole cigarette, and a residual tobacco portion 1c .
  • process 100 is suitable to enable reuse of filters 1a, which are usually made of cellulose acetate, paper, cotton or mixed cotton and paper.
  • Process 100 is preferably obtained through use of a device 2 adapted to perform extraction of the harmful substances from butt 1.
  • device 2 comprises a container 2a defining an inner chamber adapted to house a basket 3 for receiving a plurality of butts 1, and at least one vessel 4 adapted to be brought into connection for fluid passage with basket 3 through pipes or similar elements not shown in the figure.
  • the detergent contained in vessel 4a consists of 5% sodium hypochlorite, while the second vessel 4b contains 30% hydrogen peroxide.
  • the second vessel can advantageously contain, in addition to hydrogen peroxide, colouring matter or dyes for colouring butt 1, and/or perfumed substances such as sweet-smelling oils, adapted to enable the recycled butt 1 to have a pleasant smell.
  • device 2 preferably includes a fluid actuating system 5 adapted to cause movement of said fluids, and a motor 6 for actuation of basket 3.
  • Motor 6 drives said basket 3 in rotation relative to container 2a ensuring both a high washing quality and an appropriate drying of butts 1 by centrifugation.
  • the actuating system 5 allows the fluids contained in vessels 4 to flow into the inner chamber of container 2a filling it at least partly, and to be then evacuated from said chamber during the final steps of the recycling process 1.
  • the system can be therefore advantageously obtained by a pump and a series of pipes.
  • device 2 can advantageously comprise a filling unit 7 adapted to store butts 1 and enable basket 3 to be filled.
  • the filling unit 7 can therefore advantageously consist of a hopper, i.e. a container in the form of a truncated pyramid or cone turned upside down, provided with a hole at the bottom with a controlled opening allowing butts 1 to come out therethrough, so as to fill basket 3.
  • the invention i.e. process 100 for cigarette butt and other product recycling consists in the following sequence of operations, shown in Fig. 3 : a removing step 10 , a loading step 20 , a washing step 30 , a rinsing step 40 .
  • the removing step 10 contemplates elimination of at least tobacco 1c from butt 1. Therefore tobacco 1c is removed and separated from the rest of butt 1 which, at this point, consists of filter 1 a and envelope 1 b. Alternatively, during the removing step, envelope 1 b can be also removed together with tobacco 1 c, so that the filter alone is submitted to process 1.
  • This removing step 10 preferably takes place by dipping the butts in hot water, i.e. at a temperature included between 30°C and 90°C, over a period of time preferably in the range of 3 to 30 hours.
  • butt 1 is introduced into unit 7.
  • unit 7 is activated so that it fills basket 3 with butts 1, said basket 3 being subsequently disposed inside container 2a.
  • unit 7 can advantageously fill basket 3 when said basket is placed in container 2a.
  • the washing step 30 is carried out.
  • the fluid actuating system 5 is activated and it allows the detergent, or substantially the clear water, contained in vessel 4a to fill the inner chamber of container 2a at least partly.
  • Motor 6 sets basket 3 in rotation enabling the detergent to come into contact with all butts 1 contained in basket 3.
  • the detergent is absorbed by filter 1 a and by envelope 1b, if present.
  • motor 6 submits butts 1 to centrifugation, i.e. it sets the basket in rotation at such a speed that all detergent is ejected from each butt 1.
  • said operation allows not only the detergent to be removed from said butt, but also a first portion of the polluting substances present in filter 1a to be taken out. This operation is made possible by system 5 extracting the detergent from container 2a and promoting removal of said detergent from butt 1.
  • Process 100 is then completed by a rinsing step 40.
  • the fluid actuating system 5 introduces the fluid coming from vessel 4b into container 2a, which fluid is thus absorbed by butt 1.
  • the fluid as previously described, is preferably made up of sweet-smelling oils and hydrogen peroxide, said hydrogen peroxide enabling the foreign substances still present in the butt to be removed, i.e. the residual harmful substances and the detergent possibly still present after the preceding washing step 30.
  • process 100 and therefore the rinsing step 40 is completed by new activation of motor 1 centrifuging basket 3 again, thereby causing said fluid to come out from the butt, which is therefore almost free from polluting substances.
  • the invention allows achievement of important advantages.
  • process 100 enables butt 1 to be recycled in a simple and cheap manner.
  • the process due to use of the particular detergent, allows almost the whole of the harmful substances present in filter 1c to be eliminated.
  • the liquid from washing 30, in particular when washing is carried out with water alone, or also resulting from the removal step 10 of the cigarette butts, contains nicotene and can therefore be utilised for eliminating deposits and oxidation from pipelines for oil and gas, in particular in case of petroleum and various hydrocarbons.
