Journal of Material Cycles and Waste Management. The paper makes analyses and evaluation of work progress in asbestos inventory, as well as removal asbestos and asbestos products in Poland in regional scale i. It was clearly observed in the light of research that quantity of asbestos and asbestos-derived products is significantly much higher in eastern and central regions of Poland, which is a consequence of historical—economic conditions.
Its commercial use started in 2nd half of 19th c, together with the development of demand for insulation for the burgeoning steam technology [ 1 ].
Together with common asbestos exploitation, the material releasing to the air took place, which resulted in negative influence on human health as well as on other components of natural environment. Asbestos, due to its properties, i.
Its common use in building asbestos-cement tiles and pipes , in power engineering high chimneys, where dilatations are filled with asbestos ropes, heating routes insulation—asbestos-cement coats , in transport industry engine thermal insulations of motor vehicles and exhaust manifolds , in chemical industry asbestos membranes used in electrolytic chlorine production , in military sector, in textile industry incombustible textiles used by firemen , but also in other branches of national economy, made asbestos the cause of many negative phenomena and processes [ 5 , 6 , 7 , 8 , 9 , 10 ].
It is difficult to state univocally the scale of asbestos mining and exploitation. Polish territory according to estimations made in reported about Destructive influence on human health of asbestos and asbestos products made majority of the world countries prohibit its usage.
As it was mentioned above, Poland also introduced in the legislation prohibiting using products containing asbestos, introducing them to the market, as well as restrictions on production and purchase. Poland, which became a member of European Union in is obliged to follow the Union legislation since 1st January , which prohibits producing and purchasing asbestos products obligatory for all EU countries and complete neutralization of the products and their waste until Completing the goals of the other program due to relatively long—at least 30 year durability of asbestos-cement boards and other asbestos materials used in building was prolonged until Source: own study based on the data [ 14 ].
It should be pointed out, that asbestos negative effects on human health is the issue the most often discussed by scientists, politicians and practitioners, both in Poland and the world [ 12 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. Pathogenic asbestos impact is the reason of many diseases, such as: asbestosis, idiopathic pulmonary fibrosis, mesothelioma and other types of cancer by inhaling asbestos fibres present in the air [ 25 , 26 , 27 , 28 ].
Biological aggressiveness of asbestos dust is related with the level of penetration and quantity of fibres in lower part of a respiratory system. Due to asbestos harmfulness, both at the mining stage and its use in various products over , present tendency is to make careful inventories of both processes [ 29 ]. In this context, it is vital to register asbestos quantities in particular countries as one of pathogenic factors , remove and neutralize asbestos products, build and shape social awareness concerning knowledge on asbestos danger, especially, as some countries, like: India and China are still using asbestos as building material [ 30 ].
The most important asbestos producers include at present Russia, Brasil, China, and Kazakhstan, where manufacturing the material in amounted, respectively: , , and thous. The paper goal is to analyze and estimate work progress in asbestos inventory making, removing asbestos products in Poland in regional scale i.
What was the size and dynamism of changes in asbestos use in Poland in twentieth century? What is the scale of listed asbestos quantities in Poland until the half of and what is its regional diversity? Is there any dependence between listed asbestos quantities and the mass still waiting for removal and the level of urbanization percentage of population inhabiting cities and if there is any correlation between listed asbestos quantity and still waiting for removal and a number of buildings erected between and when asbestos was commonly used as building and engineering constructive material?
How many waste dumps, where asbestos is stored and neutralized, are there in Poland and what is their localization and how much of that harmful material has been disposed stored until presence? The group created Asbestos Base which is still updated.
The scale of listed asbestos is performed by filling annual information form in which an owner, manager or property user reports to proper authority mayor, town president or directly a marshal locations, where asbestos or products containing asbestos were or are still in use. Only six communes did not report asbestos presence or local administrative authorities did not report its presence to the Base. These queries indicated that locations defined in The Asbestos Base as places containing asbestos and requiring its urgent removal did not contain asbestos any longer, which shows that data base is not always a reliable source.
The observation leads also to conclusion that rural property owners are more disciplined in reporting proper authorities asbestos presence or its removal, while in urban spaces, this negligence often results from lack of information, where the fact of removing asbestos material should be reported.
In majority of Polish cities listed asbestos is classified as very urgent to be removed and although it has already been disposed, the facts have not been reported to the Base. Poland uses three levels of urgency in asbestos removal, expressed by three information colors: red, orange and yellow. The authoresses use in the elaboration various methods of the obtained results quantification, processing and presentation. To characterize some dependences between quantity of listed asbestos and selected social-economic features urbanization level, a number of buildings erected between and , when asbestos was rather commonly used for building and constructive-engineering purposes , correlation coefficients were measured with statistical significance 0.
Furthermore, regression analysis was made, taking into account quantity of listed designed for disposal asbestos and percentage of urban populations. Economy of every country is based on human and natural resources—local or imported, as not all country resources are sufficient for industrial exploitation and use in economy.
Social-economic development taking place after First and Second World War, including intense building investment and industrial boom caused increased need and import of asbestos.
It must also be remarked that asbestos-cement boards production started in Poland in and was continued until , when the Act of 19th June was passed prohibiting usage of products containing asbestos [ 32 ]. Asbestos and products containing asbestos import to Poland between and Source: own study based on the data [ 33 ]. First asbestos-concrete boards factory after Kuczumow and Nowak [ 34 ] was built in Krakow in , next in Lublin in and just after Second World War another plants in Lublin, Ogrodzieniec, Wierzbica and Szczucin.
Total of 24 plants using asbestos in their production functioned in Polish territories. The highest rate of asbestos and its products import was observed between and Fig. Average annual asbestos import amounted about 78 thous. As it is reported in the research import decrease was observed after Fig.
It must be remarked here, however, that as Albin et al. It is worth mentioning that in global scale asbestos production in the years of its highest popularity, i. Countries like: China, India, Brazil, Argentina, Russia, Kazakhstan, Canada and Zimbabwe were the biggest asbestos and asbestos products manufacturers in The data reports that in Canada and Zimbabwe gave up asbestos production, Chile Russia increased it to 1.
It must be emphasized once again that Poland introduced relatively early in the restrictions for using asbestos and asbestos products and regulations concerning asbestos removal from the country space. It was rather new initiative, whereas USA, for example, limited asbestos production and use in , and EU itself passed respective restrictions as late as in It should be addend that Denmark was the first country to ban using asbestos for thermal, acoustic insulation, waterproofing [ 31 ].
It also should be remembered that legislation introduced in a number of countries concerning the problem varied, e. At present, following the International Ban Asbestos Secretariat production and use of asbestos and asbestos products is banned in 65 countries of the world [ 31 ]. It was estimated for Poland that in there were On the other hand, it is not possible to obtain the information in case of many other products containing asbestos, because they are often included in smaller import of machinery and other appliances.
Quantity of asbestos products in ton in Poland listed and designed for removal state for 30th June and mass of neutralized waste containing asbestos. Source: own study based on the data [ 40 , 41 ]. The research pointed out that central and eastern Poland regions report the highest number of listed asbestos products, what is a result of certain historical—economic conditioning and reflects to some degree development level of different parts of Poland being under partition by the year For instance—in relatively poorly developed part under Russian partition roofs covers were of law quality, with predominant thatch, straw, wooden shakes what ecological awareness!
Present study indicated that there is significant dependence between quantity of listed asbestos and derived products designed for removal and a number of buildings from to , when asbestos was commonly applied for building and engineering purposes Fig.
Number of buildings from to and quantity of listed asbestos in Polish voivodeships. Explanations: a Total number of buildings from to , b Total quantity of listed asbestos in voivodeships in thous. Source: own study based on the data [ 40 , 43 ].
Rural character is also observed as predominant in Podlasie or Central Poland. High asbestos presence there is confirmed by research of Buczaj et al. Dependence between the urbanization degree and quantity of listed asbestos in Poland in poviats.
Taking above discussion into consideration there are some problems arising. First general issue for Poland is the necessity of making complete inventory of all asbestos products.
The situation may have resulted from the fact that its presence has not been reported by an owner of a building or other property containing asbestos to respective authority, which consequently follows the material removal or replacing it with other material the other solution is applied the most often in case of roofs or building fronts , next transport it to specially prepared dumps and secure it, what generates high costs. In some regions of Poland, rural ones in particular, there is also an aspect of local society protests, as dismantling asbestos insulation, e.
Older farmer generations are not so eager to exchange functional and cheap roofs which serve the purpose to expensive, but healthier new ones, moreover, that they have not experienced any direct pathogenic consequences of asbestos affects on human health. Therefore, the problem of asbestos disposal has become in Poland and other world countries an issue of economic, financial, social and ecological significance.
While pro-health reasons appeal to a society, relatively small number of disease cases caused by asbestos and their limitation to persons directly working with the material causes the situation that asbestosis and other derivatives are commonly treated as exotic diseases, which significantly diminishes understanding the problem essence and threatening danger. Another issue, difficult to solve is individual economic interest, because not all Polish communes provide equal co-financing the costs of asbestos removal.
Sum of that allowance can evidence that officials are resourceful and care for common local good. At this stage of social-economic world development there are many problems requiring rapid reaction and solution. These are, besides desertification and lack of water, nuclear weapon and terror threats as well as ecological challenges. For a human and other living organisms it is vital to reduce and dispose harmful asbestos products used commonly in the past.
We all realize the necessity of their instant neutralization. At present the only acceptable method of waste containing asbestos disposal is its storage in special dumps for hazardous waste or separated sectors of other landfills.
It must be remembered, though, that just like general definitions of preventing, diminishing and waste reusing differ in various countries and regions [ 45 , 46 ], asbestos disposal methods also differ in various parts of the world. The most efficient methods of asbestos disposal are being discussed in scientific centers, in view of the fact that asbestos waste storage seems to be only a temporal solution. Japan, for instance, promotes asbestos waste inertization and its thermal processing [ 47 , 48 ].
Research on recycling technology for asbestos waste is being in progress, but due to high costs and special laboratory conditions necessary, the methods are not used in practice [ 49 , 50 , 51 , 52 , 53 ].
Tests of Gidarakos et al. Asbestos waste belongs to hazardous waste; therefore, its management requires special procedure and strict control. Following legislation obligatory in Poland, programs for environment protection are implemented with its integral element, which is waste management plans for waste management on country, voivodeships, poviats and communes level.
An owner of a property is obliged to report asbestos products for removal and disposal storage to a special territory administration unit, although, as it was remarked earlier, financial factor is the main obstacle, as an owner is responsible for all the costs concerning asbestos removal, e.
One of the ways to hasten the removal process and protect the environment from threat caused by improper asbestos waste management is what has already been mentioned support from the part of self-government authorities in co-financing these actions e. Poland has strict legal regulations concerning procedures of dismantling asbestos-cement roof covers, which are included in the Regulation of the Minister of Economy from 14th August concerning save use and conditions of removing products containing asbestos [ 56 ].
In accordance with obligatory executive order removal works must be performed solely by certified firms, equipped with special technical facilities designed for the purpose and qualified staff. There are at present firms functioning in the area of the country for dismantling and transporting asbestos Fig. These rigorous regulations are designed to reduce negative effects on human health, in particular persons working with the material removal.
Hazardous waste landfills, where asbestos is neutralized and a number of firms removing asbestos in voivodeships state from 30th June Source: own study based on the data [ 40 ]. The survey and analyses show that until now the process of removing and neutralizing asbestos storage has been performed much more slowly than it was planned. Between and total of 1. One fact is alarming that by the end of June even the quantity planned for — for neutralization had not been completed.
The paper makes analyses and evaluation of work progress in asbestos inventory, as well as removal asbestos and asbestos products in Poland in regional scale i. It was clearly observed in the light of research that quantity of asbestos and asbestos-derived products is significantly much higher in eastern and central regions of Poland, which is a consequence of historical—economic conditions.

When and where was asbestos used?
As well as an insulation and fireproofing aid, asbestos cement was used due to the fact that it is weatherproof in that, although it will absorb moisture, the water does not pass through the product. Corrugated sheets, slates, moulded fittings, soffits and undercloak, water cisterns, rainwater gutters, down pipes, pressure pipes, underground drainage and sewer pipes, sills, copings, chalkboards, fascias, infill panels, etc. It is sometimes difficult to tell the difference between an asbestos cement product and a low-density insulation board. Where the product has been used as a roofing or cladding product open to the weather , you can be confident that the product is asbestos cement. If the material is moulded then it will be asbestos cement, as low-density products were not moulded, except as half rounds for pipe lagging.

Asbestos is the generic term for a group of naturally occurring fibrous minerals with high tensile strength, flexibility, and resistance to thermal, chemical and electrical conditions. Asbestos fibers are of high-tensile strength, flexible, heat and chemical resistance, and good frictional properties. Cement is the most essential raw material in any kind of construction activity. Ceramics also known as fire clay is an inorganic, non-metallic solid article, which is produced by the art or technique of heat and subsequent cooling. Limestone is a sedimentary rock, mainly composed of calcium carbonate CaCO3. It is the principal source of crushed stone for construction, transportation, agriculture, and industrial uses. Emerging applications in commercial sectors such as asbestos, cement and ceramic are poised to fuel demand in the coming years. Growing demand for limestone in the production of cement as well as in several other chemicals that are used in the production of high-value every-day products offers significant opportunities for growth. Global Limestone consumption is projected to reach 5. Presently, cement production is million tonnes and expected to double to reach almost million tonnes in future.

All are composed of long and thin fibrous crystals , each fiber being composed of many microscopic 'fibrils' that can be released into the atmosphere by abrasion and other processes. Asbestos is an excellent electrical insulator and is highly resistant to heat, so for many years it was used as a building material. Inhalation of asbestos fibres can lead to various serious lung conditions, including asbestosis and cancer.
If you think you've found asbestos in your home, the first thing is: don't panic - but don't touch it. Asbestos in the home is a risk when it is disturbed in a way that produces fibres or dust containing asbestos fibres. This could include demolition work, renovating, drilling or doing work in or on roofs, around insulated pipes, and so on.
