Disposal of railway sleepers is one of the most global problems transport industry. Despite the fact that the main material of the sleepers is wood, they cannot be called safe due to various chemical impregnations (most often it is poisonous creosote). If disposed of incorrectly, this substance can harm not only the environment, but also human health. Our company offers high-quality and inexpensive services for the disposal of sleepers throughout Russia.

Recycling process

The simplest and most popular way to dispose of wooden railway sleepers is incineration. At the same time, due to the harmful substances released from the impregnation, it is still not completely safe. Gasification is more acceptable - the process of converting fuel into a pulverized stream. Another equally popular and absolutely safe method is pyrolysis. To date, this is the most promising way to dispose of railway sleepers, in which there are no emissions into the atmosphere. In addition, pyrolysis is very beneficial for enterprises, since in the future it is possible to use products obtained during processing (fuel, gas, coal).

Sleeper disposal: problems and solutions

The problem of disposal of sleepers impregnated with oil antiseptic is growing every year. Due to the overcrowding of regional landfills, units railway Quite often, sleepers are stored in places not intended for this. This, in turn, can cause global environmental problems. In addition, such unauthorized burial is prohibited by law. Utilization of wooden sleepers used closes life cycle product, and can also serve as an alternative source of energy.

The cost of recycling wooden sleepers

Disposal of impregnated sleepers is more expensive than without a septic tank. This affects the final cost of the service. In general, our company offers a decent level of work at an affordable price. The cost of recycling wooden sleepers depends on several factors:

  • Remoteness of the place of sampling of raw materials;
  • The chosen disposal method;
  • Degrees of processing;
  • The volume of raw materials.

We care about the preservation of the environment and strive to improve the environmental situation in the country.

For companies and organizations in the field of railway construction, maintenance of transport networks, there are requirements for the disposal of worn out or unclaimed sleepers. Wooden sleepers today pose a huge threat to the environment, they are abandoned, transferring all railway tracks to concrete bases. But the dismantling of old equipment requires a quality approach to disposal. It is worth considering more closely the reasons for the need for such a process.

Why should railroad ties be recycled?

If the concrete elements of the supporting structure are simply broken and then used in construction for backfilling, then the wooden products must be disposed of in an environmentally friendly way. Previously, such railway waste was simply burned. But today this is unacceptable, since the harm from the emitted substances has been proven and confirmed by research. The main aspects of influence are as follows:

  • release of creosote during combustion, significant air pollution with toxic substances;
  • contamination of air masses with other toxic compounds of the phenolic group, acetone and other materials;
  • combustion of coal oil, which was impregnated with wooden parts of the supporting structure;
  • incomplete processing of some chemical elements, subsequent pollution of the landfill.

All this leads to the fact that during active processing with the help of simple incineration, the sleepers continue to pollute the environment without generating solid waste. Today, there are more adequate approaches to the procedure for the disposal of wooden sleepers, while the price of the process remains affordable, and the company, upon completion, must issue a complete package of documents to the customer.

Sleeper disposal - the main tasks of a complex process

There are several options for chemical treatment of products before destruction. These procedures are carried out to neutralize the main harmful substances. Pyrolysis, for example, completely neutralizes some resins and chemicals that are not destroyed during combustion. With professional disposal of wooden sleepers, you can get the following results:

  • absolute destruction of all chemical compounds unacceptable for nature even before processing;
  • shredding wood residues that no longer pose a significant environmental hazard;
  • destruction of all solid residues by incineration in special furnaces without air pollution;
  • the use of methods of accelerated decomposition with the addition of reagents for destruction without access to oxygen.

All of these processes are used by professional hazardous waste disposal companies. Sleepers belong to the third class of substances according to the danger of environmental pollution. This is toxic waste from transportation networks that needs to be recycled. The need for such processes is also indicated by law, and there are a number of sanctions and fines for violation of such requirements.

The problem of utilization of railway sleepers is the most acute for the transport industry. Sleepers withdrawn from the route are subject to burial at regional industrial waste landfills, however, due to their overcrowding, they are often stored in places not intended for their storage. Unauthorized disposal of hazardous waste is often costly to their owners in accordance with legislation. Meanwhile, recycling not only closes the life cycle of a product, but at the same time can become an alternative source of energy and valuable raw materials.

Problems of utilization of spent railway sleepers. To increase the service life of wooden sleepers in the Russian Federation, mainly coal (coal oil) and petroleum (thermocatalytic liquid (GIT)) antiseptics are used. These antiseptics contain organic compounds with high volatility, toxic, carcinogenic properties.

Coal creosote (impregnating) oil is a product of the distillation of coal tar at a temperature of 200 to 400 °. It is a dark brown liquid specific gravity 1.05-1.10 g / cm3, boiling point 180-200 Co) with a pungent aroma.

The peripheral part of the sleeper consists of 80% coal oil, which, in turn, contains 20.1% phenols, 17.2% phenanthrenes, 16.9% pyrenes, 22% acetone and 12% butanol. These compounds, once in the air, can cause severe poisoning in humans and the appearance of cancer.

Currently, up to 75% of the railway tracks in Russia and neighboring countries are laid using wooden sleepers. An analysis of the comparison of the advantages and disadvantages of wooden and reinforced concrete sleepers suggests that this ratio is unlikely to change in favor of the latter. The total annual output of sleeper impregnation plants (ShPZ) is 7.75 million sleepers and 3,770 sets of beams for turnouts. In addition, more than 500 thousand tons of wooden sleepers impregnated with antiseptics have now been accumulated in the subdivisions of Russian Railways. Regional industrial waste landfills are overcrowded, and road departments are forced to glow old sleepers in places not intended for their storage. Such unauthorized disposal of waste leads to environmental payments, which, when waste of the 3rd hazard class is placed at toxic waste landfills, amount to 1288.2 rubles / ton.

Environmental strategy of Russian Railways. "ENVIRONMENTAL STRATEGY OF RZD JSC FOR THE PERIOD UP TO 2015 AND PERSPECTIVE UP TO 2030" as the goal is indicated:

  • reduce by 30% accumulated during the last economic activity unutilized waste (used wooden and reinforced concrete sleepers, contact network supports, screenings of crushed stone ballast, oily waste, etc.);
  • to increase up to 40% the level of use of waste as a source of secondary materials and energy resources.
  • to increase up to 70% the level of use of waste as a source of secondary materials and energy resources;
  • ensure the complete neutralization and disposal of waste accumulated in the course of past economic activities;
  • ensure complete neutralization and disposal of the current generation of waste.

In this regard, the problem of completing the life cycle of these products comes to the fore more and more, namely: efficient and economically feasible disposal of sleepers of various types.

Specialists of CJSC "Energy Schemes and Technologies" offer equipment for the disposal of used sleepers based on gasification technology, which allows solving all the pressing problems, namely, to ensure:

  1. The required productivity of waste disposal in accordance with the deadlines specified in the environmental strategy of Russian Railways.
  2. Required environmental performance in the recycling process.
  3. The use of sleepers as fuel for the production of electrical energy for the own needs of Russian Railways.
  4. Substitution of a significant amount of coal fuel in departmental boiler houses for a renewable type of fuel - spent railway sleepers.

All this will make it possible to logically close the life cycle of used wooden railway sleepers, giving them the opportunity to effectively work out again at the final stage of their existence.

Description of the technology for recycling used railway sleepers using gasification technology.

It is known that the dispersion and homogenization of biofuels reduces the incompleteness of combustion of hydrocarbon compounds, while the degree of neutralization of existing harmful impurities increases many times over in comparison with conventional combustion.

A prerequisite for the subsequent successful and environmentally friendly disposal of sleepers is their preliminary grinding into chips on a chipper, and possible preliminary drying to a relative humidity of not more than 20%. To ensure the normal operation of the chipper, all metal objects from the sleeper must be removed. According to available information, with the presence of the simplest auxiliary tool, one worker is able to remove the remaining metal from up to 100 used sleepers per shift from the zone of their intermediate placement before disposal.

The basic part of the proposed complex is the gas generator of the inverted gasification process. The nature of obtaining coal tar is similar to the nature of the formation of pyrolysis resins in the process of gasification of wood.

Gasification of sleepers, previously crushed into chips and dried to the required moisture content, is carried out by its thermal decomposition with a lack of oxygen at a temperature of 900-1100 Co. At the same time, the antiseptic (creosote) present in the wood chips, in parallel with the release of volatiles from the wood, passes into a gaseous state. Sequentially occurring during gasification, first oxidative, then, when the gases pass through a layer of hot coal, reduction processes ensure the production of generator gas as a result of thermochemical reactions. The gas obtained in the gas generator, containing combustible gases: hydrogen, carbon monoxide (carbon monoxide) and a certain amount of methane, can be used both for thermal use by burning in special burners, and for the production of electricity after its preliminary purification and cooling.

Ј¬"Still, weeks and years ran on, and my hair began to vail me with its fullness and its length; and now often I heard the word beautiful, spoken of my hair, and beautiful, spoken of myself. They would not say the word openly to me, but I would by chance overhear them whispering it. openness of their saying beautiful, to me; and I know it would have filled me with all conceivable kindness towards every one. Now I had heard the word beautiful, whispered, now and then, for some months, when a new being came to the house; they called him gentleman. His face was wonderful to me. Something strangely like it, and yet again unlike it, I had seen before, but where, I could not tell. But one day, looking into the smooth water behind the house , there I saw the likenessЎЄsomething strangely like, and yet unlike, the likeness of his face. The new being, the gentleman, he was very gracious to me; he seemed astonished, confounded at me; he looked at me, then at a very little, round pictureЎЄso it seemedЎЄwhich he took from his pocket, and yet concealed from me. Then he kissed me, and looked with tenderness and grief upon me; and I felt a tear fall on me from him. Then he whispered a word into my ear. "Father," was the word he whispered; the same word by which the young girls called the farmer. Then I knew it was the word of kindness and of kisses. I kissed the gentleman. This solecism once vividly and practically apparent; then comes the earnest reperusal of the Gospels: the intense self-absorption into that greatest real miracle of all religions, the Sermon on the Mount. From that divine mount, to all earnest loving youths, flows an inexhaustible soul-melting stream of tenderness and loving-kindness; and they leap exulting to their feet, to think that the founder of their holy religion gave utterance to sentences so infinitely sweet and soothing as these sentences which embody all the love of the Past, and all the love which can be imagined in any conceivable Future . Such emotions as that Sermon raises in the enthusiastic heart; such emotions all youthful hearts refuse to ascribe to humanity as their origin. This is of God! cries the heart, and in that cry ceases all inquisition. Now, with this fresh-read sermon in his soul, the youth again gazes abroad upon the world. Instantly, in aggravation of the former solecism, an overpowering sense of the world"s downright positive falsity comes over him; the world seems to lie saturated and soaking with lies. The sense of this thing is so overpowering, that at first the youth is apt to refuse the evidence of his own senses; even as he does that same evidence in the matter of the movement of the visible sun in the heavens, which with his own eyes he plainly sees to go round the world, but nevertheless on the authority of other persons,ЎЄthe Copernican astronomers, whom he never sawЎЄhe believes it not to go round the world, but the world round it. with lies; but in reality it does not so lie soaking and saturate; along with some lies, there is much truth in this world. accursed; and that at all hazards men must come out of it. But why come out of it, if it be a True World and not a Lying World? Assuredly, then, this world is a lie.

єй¶ami ЈєAt last we got as far as the Narrows, which every body knows is the entrance to New York Harbor from sea; and it may well be called the Narrows, for when you go in or out, it seems like going in or out of a doorway; and when you go out of these Narrows on a long voyage like this of mine, it seems like going out into the broad highway, where not a soul is to be seen. For far away and away, stretches the great Atlantic Ocean; and all you can see beyond it where the sky comes down to the water. It looks lonely and desolate enough, and I could hardly believe, as I gazed around me, that there could be any land beyond, or any place like Europe or England or Liverpool in the great wide world. It seemed too strange, and wonderful, and altogether incredible, that there could really be cities and towns and villages and green fields and hedges and farm-yards and orchards, away over that wide blank of sea, and away beyond the place where the sky came down to the water. And to think of steering right out among those waves, and leaving the bright land behind, and the dark night coming on, too, seemed wild and foolhardy; and I looked with a sort of fear at the sailors standing by me, who could be so thoughtless at such a time. But then I remembered, how many times my own father had said he had crossed the ocean; and I had never dreamed of such a thing as doubting him; for I always thought him a marvelous being, infinitely purer and greater than I was, who could not by any possibility do wrong, or say an untruth. Yet now, how could I credit it, that he, my own father, whom I so well remembered; had ever sailed out of these Narrows, and sailed right through the sky and water line, and gone to England, and France, Liverpool, and Marseilles. It was too wonderful to believe.

"So long as no method of attractive labor has been devised, it will continue to be true that "there must be many poor in order that there may be a few rich;" a mean and hateful saying, which we hear every day quoted as an eternal truth from the mouths of people who call themselves Christians or philosophers. in this case, there is nothing but poverty that will force men to labor.

Looking beyond the present period, Mrs. Glendinning could not but perceive, that even in Lucy's womanly maturity, Lucy would still be a child to her; because, she, elated, felt, that in a certain intellectual vigor, so to speak, she was the essential opposite of Lucy, whose sympathetic mind and person had both been cast in one mold of wondrous delicacy. But here Glendinning was both right and wrong. So far as she here saw a difference between herself and Lucy Tartan, she did not err; but so farЎЄand that was very farЎЄas she thought she saw her innate superiority to her in the absolute scale of being, here she very widely and immeasurably erred.
