Abstract

Environmental protection is one of the objectives of the implemented concept of sustainable development and circular economy. The construction industry and its products (building objects) have a large contribution in negative influences, therefore all actions limiting them are necessary. One way of doing this is to apply substitution to existing unfavourable solutions, both in terms of construction and materials as well as technology and organization. The aim of the article was to determine the key factors conditioning the use of substitution at each stage of the investment and construction cycle, leading to environmental protection. The research paid attention to the use of substitute recycled products. The defined factors were subjected to a SWOT analysis and then, using the DEMATEL method, cause-andeffect relationships were identified that determine development in the application of substitution in the environmental context of sustainable and closed-cycle construction. The analysis was carried out by using a summative, linear aggregation of the values of the position and relationship indicators.

Abstract

In the constant pursue of the sustainability of socio-industrial systems, the definition of useful, reliable and informative, and at the same time simple and transparent, indicators is an important step for the evaluation of the circularity of the assessed systems. In the circular economy (CE) context, scientific literature has already identified the lack of overarching indicators (social, urban, prevention-oriented, etc.), pointing out that mono-dimensional indicators are not able to grasp the complexity of the systemic, closed-loop, feedback features of CE. In this respect, Emergy accounting is one of the approaches that have been identified as holding the potential to capture both resource generation and product delivery dimensions and therefore to provide an enhanced systems’ evaluation in a CE perspective.

Because of Emergy’s intrinsic definition and its calculation structure, Emergy-based indicators conceptually lend themselves very well to the evaluation and monitoring of circular processes. Additionally, Emergy has the unique feature of enabling the evaluation of systems that are not necessarily only technosphere systems, but also of technological systems which embed nature (techno-ecological systems).

The present paper gives a perspective on a set of Emergy-based indicators that we have identified as suitable to evaluate circular systems, and outlines the different perspective compared to the circularity indicators defined in the “Circularity Indicators Project” launched by the Ellen MacArthur Foundation.

Abstract

Municipal waste management has been an area of special interest of the European Commission (EC) for many years. In 2018, the EC pointed out issues related to municipal waste management as an important element of the monitoring framework for the transition towards a circular economy (CE), which is currently a priority in the economic policy of the European Union (EU). In the presented monitoring framework, 10 CE indicators were identified, among which issues related to municipal waste appear directly in two areas of the CE – in the field of production and in the field of waste management, and indirectly – un two other areas – secondary raw materials, and competitiveness and innovation. The paper presents changes in the management of municipal waste in Poland in the context of the implementation of the CE assumptions, a discussion of the results of CE indicators in two areas of the CE monitoring framework in Poland (production and waste management), and a comparison of the results against other European countries.

In Poland, tasks related to the implementation of municipal waste management from July 1, 2013 are the responsibility of the municipality, which is obliged to ensure the conditions for the system of selective collection and collection of municipal waste from residents, as well as the construction, maintenance and operation of regional municipal waste treatment installations (RIPOK). The municipality is also committed to the proper management of municipal waste, in accordance with the European waste management hierarchy, whose overriding objective is to prevent waste formation and limiting its amount, then recycling and other forms of disposal, incineration and safe storage. The study analyzed changes in the value of two selected CE indicators, i.e. (1) the municipal waste generation indicator, in the area of production and (2) the municipal waste recycling indicator, in the area of waste management. For this purpose, statistical data of the Central Statistical Office (GUS) and Eurostat were used. Data has been presented since 2014, i.e. from the moment of initiating the need to move to the CE in the EU. In recent years, there has been an increase in the amount of municipal waste generated in Poland as well as in the EU. According to Eurostat, the amount of municipal waste generated per one inhabitant of Poland increased from 272 kg in 2014 to 315 kg in 2017. It should be noted that the average amount of municipal waste generated in Poland in 2017 was one of the lowest in EU, with a European average of 486 kg/person. Poland has achieved lower levels of municipal waste recycling (33.9%) than the European average (46%). The reason for Poland’s worse results in the recycling of municipal waste may be, among others, the lack of sufficiently developed waste processing infrastructure, operating in other countries such as Germany and Denmark, and definitely higher public awareness of the issue of municipal waste in developed countries. Municipal waste management in Poland faces a number of challenges in the implementation of GOZ, primarily in terms of achieving the recycling values imposed by the EC, up to a minimum of 55% by 2025.

Abstract

The concept of a Circular Economy assumes that the value of products, materials and resources is to be maintained in the economy for as long as possible to ultimately reduce waste generation to a minimum. In this concept, raw materials are repeatedly put into circulation many times, often passing from one branch of industry to another. So energy, water, metal ores, oil, gas, coal and others, and wherever possible, their replacement with renewable resources (wind and solar energy, natural resources). It is important, and this is the essence of the Circular Economy, the maximum re-use of scarce materials and raw materials from already produced and used products. This concept has found the support of the European Commission and activities in this area will successively be implemented through appropriate legal acts of the European Union. The need to implement solutions in the field of minimizing the consumption of raw materials, materials and energy or reducing waste production is also felt by consumers and industry. The packaging industry is particularly interested in implementing the concept of a Circular Economy. Due to the dynamic growth of the packaging market, which in 2017 reached around EUR 9.6 billion in Poland (data from the Polish Chamber of Packaging) and the increasing amount of post-consumer waste, it is necessary to introduce solutions limiting the consumption of raw materials and energy throughout the product life cycle.

The aim of the article is to present current practices regarding the reduction of the negative impact of packaging on the environment and the indication of directions for the implementation of the Circular Economy concept in the packaging industry.

Abstract

The circular economy model is based on several priority areas, including biomass and bio-based products. Focusing on them and their use should certainly take their cascading into account use, including how energy from waste from the wood industry is managed. Biomass is one of the most frequently used renewable energy sources in Poland, and in the European Union it satisfies 6% of primary energy. The CE (Circular Economy) model assumes that the reuse, processing and regeneration of a product requires less resources and energy, and is more economical than conventional material recycling, as low quality raw materials. The current model of waste management must take energy recovery into account, without which it is impossible to close the balance sheet of management of many groups of waste. This is also important from the economic point of view. Chemical energy, which is contained in a large part of waste, can be used for energy purposes, including the production of electricity and heat. Reducing the use of raw materials is the most effective environmental approach to solving the waste problem. However, this requires reducing the extraction and consumption of materials, challenging existing production and consumption patterns. In the circular economy model there is a huge difference in approach to recycling leading to new products that create transport and production, new jobs and possible GDP (Gross Domestic Product) growth. The aim of the study is to analyze the use of waste from the wood industry and to present possible solutions for its cascade use, taking the currently implemented circular economy model (CE) into account.

Abstract

The aim of our research is to gain understanding about material flow related information sharing in the circular economy value network in the form of industrial symbiosis. We need this understanding for facilitating new industrial symbiosis relationships and to support the optimization of operations. Circular economy has been promoted by politics and regulation by EU. In Finland, new circular economy strategy raises the facilitation of industrial symbiosis and data utilization as the key actions to improve sustainability and green growth. Companies stated that the practical problem is to get information on material availability. Digitalization is expected to boost material flows in circular economy by data, but what are the real challenges with circular material flows and what is the willingness of companies to develop co-operation? This paper seeks understanding on how Industry 4.0 is expected to improve the efficiency of waste or by-product flows and what are the expectations of companies. The research question is: How Industry 4.0 technologies and solutions can fix the gaps and discontinuities in the Industrial Symbiosis information flow? This research is conducted as a qualitative case study research with three cases, three types of material and eight companies. Interview data were collected in Finland between January and March 2021. Companies we interviewed mentioned use-cases for sensors and analytics to optimize the material flow but stated the investment cost compared to the value of information. To achieve sustainable circular material flows, the development needs to be done in the bigger picture, for the chain or network of actors, and the motivation and the added value must be found for each of them.

Abstract

Circular economy – a new approach in the understanding of the human–environment relationship. The work presented the assumptions of the circular economy as a new concept of the economy functioning with the method of production “from cradle to cradle” constituting the opposition to the commonly used linear economy approach (take, make, dispose). Work discussed also the impact on the quality of human life and the management of environmental resources. Functional assumptions of the circular economy and its territorial dimension were presented, especially in urban areas where the green economy and sharing economy mechanisms are used. The potential for economic growth and the creation of new jobs was also emphasized due to the implementation of circular economy in the EU countries.

Abstract

Mining wastes are by-products generated during search, excavation and processing, both physical and chemical, of ores and other minerals. In 2017, wastes from group 01 constituted 60% of total wastes produced in Poland. According to the statistical data, approximately 92% of the waste generated during the excavation and processing of hard coal is economically reused. 30% of this waste used in industry and nearly 70% is used for the reclamation of the degraded industrial areas. At present, there is a tendency in the E uropean Union to shift from a linear economy to the Circular E conomy. The goal is to maintain economical value of the resources, among others, by their reuse in a productive way, which at the same time eliminates waste. One of the industrial branch where the ideals of a Circular E conomy can be implemented is the mining industry. Mining wastes may form one of the sources of anthropogenic minerals, as they belong to alternative aggregates. Deposits of anthropogenic minerals are considered sources of valuable raw materials which guarantee that the products made on their basis will be of high quality. The article presents the results of physico-chemical tests, the leachability of contaminations and phytotoxicity tests carried out on the basis of the selected mining waste in light of a Circular E conomy.

Abstract

In these times of the climate crisis surrounding us, the improvement of technologies responsible for the emission of the largest amounts of greenhouse gases is necessary and increasingly required by top-down regulations. As the sector responsible to a large extent for global logistics and supply chains, the fuel sector is one of the most studied in terms of reducing its harmful impact. The development of the next generations of fuels and biofuels, produced by companies using increasingly modern, cleaner and sustainable technologies, is able to significantly reduce the amount of greenhouse gases released into the atmosphere. In this case, the most effective solution seems to be the use of closed loops. Due to their low, often zero emission balance and the possibility of using waste to produce materials that can be reused, a circular economy is used in many sectors of the economy, while ensuring the emission purity of technological processes. One of the innovative solutions proposed in recent years is the installation created as part of the BioRen project, implemented under the Horizon 2020 program. The cooperation of European institutes with companies from the SME sector has resulted in the creation of an experimental cycle of modern technologies for the production of second-generation biofuels. The project involves the processing of municipal solid waste into second-generation drop-in biofuels. The entire process scheme assumes, in addition to the production of biofuels, the processing of inorganic fractions, the production of carbon material for the production of thermal energy, and the simultaneous treatment of wastewater.

Abstract

The growing increase in the use of cars and transportation in general is causing an increase the emission of pollutants into the atmosphere. The current European Union regulations impose the minimization of pollution through the use of automotive catalytic converters on all member countries, which stops toxic compounds from being emitted into the atmosphere thanks to their contents of platinum group metals (PGMs). However, the growing demand for cars and the simultaneous demand for catalytic converters is contributing to the depletion of the primary sources of PGMs. This is why there is now increasing interest in recycling PGMs from catalytic converters through constantly developing technologies. There are newer and more sustainable solutions for the recovery of PGMs from catalytic converters, making the process part of a circular economy (CE) model. The purpose of this article is to present two innovative methods of PGM recovery in the framework of ongoing research and development projects.

Abstract

This article investigates the possibilities of the recovery of raw materials at the Kraków–Płaszów municipal wastewater treatment plant (WWTP). The materials include sand coming with raw sewage and delivered by septic tankers, after cleaning sewage systems. Following the Regulation of the Minister of Climate (January 2020), sand from grit chambers is classified in the waste catalog as waste, with the code of 19 08 02. (Journal of Laws of 2020, item 10). The purchase of very efficient units has optimized the grit chamber operation and minimized the amount of waste generated as well as being an odor nuisance. The paper presents a mass balance for sand collected at the WWTP. Due to the use of new sand separators, the amount of this waste has been reduced by 28%. The paper presents the sieve curves of sand collected at the wastewater treatment plant and during the cleaning of sewage wells, as well as for sand mixtures. The sand mixture was prepared to allow some variations in the grain size characteristics of the sand. The graining differentiation indexes and curvature indexes were calculated. In addition, in laboratory tests, the leachability of heavy metals and the content of dry matter (DM) and dry mineral matter (DMM) were determined. The laboratory tests confirmed the reduction of organic solids to a level below 3% of dry weight; the content of heavy metals remained below the level of detection. The experiments confirmed that sand from the WWTP can be used as fine-grained aggregate in the production of concrete.

Abstract

The circular economy (CE) has been a European Union (EU) priority since 2014, when first official document on the CE was published. Currently, the EU is on the road to the transformation from a linear economy model to the CE model. In 2019, a new strategy was announced – the European Green Deal, the main goal of which is to mobilize the industrial sector for the CE implementation. The CE assumes that the generated waste should be treated as a secondary raw material. The paper presents an analysis of the possibility of using selected groups of waste for the production of fertilizers. Moreover, an identification of strengths and weaknesses, as well as market opportunities and threats related to the use of selected groups of waste as a valuable raw material for the production of fertilizers was conducted. The scope of the work includes characteristics of municipal waste (household waste, food waste, green waste, municipal sewage sludge, digestate), industrial waste (sewage sludge, ashes from biomass combustion, digestate) and agricultural waste (animal waste, plant waste), and a SWO T (strengths and weaknesses, opportunities and threats) analysis. The fertilizer use from waste is determined by the content of nutrients (phosphorus – P, nitrogen, potassium, magnesium, calcium ) and the presence of heavy metals unfavorable for plants (zinc, lead, mercury). Due to the possibility of contamination, including heavy metals, before introducing waste into the soil, it should be subjected to a detailed chemical analysis and treatment. The use of waste for the production of fertilizers allows for the reduction of the EU’s dependence on the import of nutrients from outside Europe, and is in line with the CE.

Abstract

In Poland, the mineral sector generates 110–130 million tons of wastes annually (in the last 20 years), and metal ore mining alone was responsible for 31.2 million tons of wastes in 2017. The slags deposited at the Polkowice were investigated. This waste may be a potential source of many valuable metals (Zn, Pb, Cu, Sb, Sn, Se). The tailings dump in Polkowice contains approximately 80,000 tons of slag. The material contains primary phases formed by pyrometallurgical processes and secondary phases, which are the result of transformation of primary components. The primary phases are represented by sulfides: sphalerite [ZnS]; wurtzite [(Zn,Fe)S]; pyrite [FeS2]; sulfates: beaverite-(Zn) [Pb(Fe3+ 2Zn)(SO4)2(OH)6]; palmierite [(K,Na)2Pb(SO4)2]; oxides and hydroxides: goethite [Fe3+O(OH)]; wüestite [FeO]; hematite [Fe2O3]; magnetite [Fe2+Fe3+ 2O4]; chromian spinel [Fe2+Cr3+ 2O4]; silicates: petedunnite [Ca(Zn,Mn2+,Mg,Fe2+)Si2O6]; quartz [SiO2]; and microcline [KAlSi3O8]. Additionally, SEM -BSE observations revealed that oxidized native metals (Cu, Pb, As) and metal alloys and semi-metals appear. The slag consists mainly of SiO2 (13.70–20.60 wt%), Fe2O3 (24.90–39.62 wt%) and subordinately of CaO (2.71–6.94 wt%) and MgO (1.34–4.68 wt%). High contents are formed by Zn (9.42–17.38 wt%), Pb (5.13–13.74 wt%) and Cu (1.29–2.88 wt%). The slag contains trace elements Mo (487.4–980.1 ppm), Ni (245.3–530.7 ppm), Sn (2380.0–4441.5 ppm), Sb (2462.8–4446.0 ppm), Se (168.0–293.0 ppm). High concentrations are formed by toxic elements, such as e.g. As (13 100–22 600 ppm) and Cd (190.5–893.1 ppm). It is estimated that the tailings dump has accumulated about 80,000 t of slag, which may contain about 10,000 t of Zn, about 6,700 t of Pb, and 1,500 t of Cu.

Abstract

The alternative waste fuels have a significant share in the fuel mix of the cement industry in Poland. The conditions inside cement kilns are favorable enough for environmentally-friendly use of waste fuels. In the article, the authors discuss the current situation concerning the use of alternative fuels in Poland, from difficult beginning in the 1990s to the present time, different kinds of fuels, and the amounts of used fuels. The use of fuels in Poland is presented against the global and EU consumption (including Central European countries and companies). The increased use of waste-derived fuels, from the level of about 1% at the end of the 1990s to the present level of about 70%, allowed for the limitation of waste storage, including avoidance of greenhouse gas emissions and consumption of conventional energy sources; those effects also contributed to the implementation of the sustainable development and circular economy conceptions. The experiences of the cement plants worldwide prove that the use of waste fuels is ecological and economical. The examples showed in the article confirm that cement plants are greatly interested in using waste fuels from waste, as they invest in the infrastructure allowing to store bigger amounts of waste and dose them more efficiently. Thus, the cement industry has become an important element of the country’s energy economy and waste management system.

Abstract

The rapid, high increase in production costs and prices of mineral fertilizers leads to a reduction in their use by farmers, while fertilizer manufacturers consider the use of alternative raw materials and reducing the energy consumption of fertilizer production processes. Given these circumstances, special attention is warranted for suspension fertilizers. The manufacturing of suspension fertilizers is simplified and less energy intensive in comparison with solid fertilizers. This is achieved by omitting certain production stages such as granulation, drying, sifting, which usually contribute to more than half of the production costs. This paper presents the production procedure of suspension fertilizers tailored for cabbage cultivation, utilizing alternative raw materials such as sewage sludge ash and poultry litter ash. The final products are thoroughly characterized. The obtained fertilizers were rich in main nutrients (ranging from 23.38% to 30.60% NPK) as along with secondary nutrients and micronutrients. Moreover, they adhere to the stipulated standards concerning heavy metal content as outlined in the European Fertilizer Regulation. A distribution analysis has showed that suspension fertilizers contain nutrients in both liquid and solid phases. This arrangement facilitates their easy availability for plants and subsequent release upon dissolution in soil conditions. To assess process consistency, the production of the most promising fertilizer was upscaled. A preliminary technological and economic analysis was also conducted. The method of producing suspension fertilizers using alternative raw materials is a simple waste management solution offering nutrient recycling with the principles of circular economy. This approach not only encourages nutrient recycling but also curtails reliance on imported raw materials.

Abstract

Failures that occurred in the last few decades highlighted the need to raise awareness about the emergent risk related to the impact localised degradation phenomena have on embankments. Common interventions aimed to improve embankments, such as the reconstruction of the damaged area or the injection of low-pressure grouts to fill fractures and burrows, may cause the weakening of the structure due to discontinuities between natural and treated zones. Moreover, since such repair techniques require huge volumes of materials, more sustainable solutions are encouraged. At the same time, the textile and fashion industries are looking for sustainable waste management and disposal strategies to face environmental problems concerned with the voluminous textile waste dispatched to landfills or incinerators. The use of soil mixed with textile waste in embankment improvement has been investigated to identify an effective engineering practice and to provide a strategy for the circular economy of textiles. Preliminary laboratory tests have been conducted on soil specimens collected from the Secchia River embankment, Northern Italy, to define the appropriate mixture proportions and to compare physical properties and hydro-mechanical behaviour of natural and treated soils. The results show that an appropriate fibre content offers manageable and relatively homogeneous mixtures. The indluence on soil consistency is mainly due to the textile fibre hydrophilic nature. The addition of fibres reduces the maximum dry density and increases the optimum water content. At low stress levels, the compressibility and hydraulic conductivity appear higher, however macro voids produced during sample preparation may alter the findings.

Abstract

This work presents results of investigations on biotrickling filtration of air polluted with cyclohexane co-treated in binary, ternary and quaternary volatile organic compounds (VOCs) mixtures, including vapors of hexane, toluene and ethanol. The removal of cyclohexane from a gas mixture depends on the physicochemical properties of the co-treated VOCs and the lower the hydrophobicity of the VOC, the higher the removal efficiency of cyclohexane. In this work, the performance of biotrickling filters treating VOCs mixtures is discussed based on surface tension of trickling liquid for the first time. A mixed natural – synthetic packing for biotrickling filters was utilized, showing promising performance and limited maintenance requirements. Maximum elimination capacity of about 95 g/(m 3·h) of cyclohexane was reached for the total VOCs inlet loading of about 450 g/(m 3·h). This work presents also a novel approach of combining biological air treatment with management of a spent trickling liquid in the perspective of circular economy assumptions. The waste liquid phase was applied to the plant cultivation, showing a potential for e.g. enhanced production of energetic biomass or polluted soil phytoremediation.

Abstract

The transition to circular economy requires diversifying material sources, improving secondary raw materials management, including recycling, and finally finding sustainable alternative materials. Both recycled and bio-based plastics are often regarded as promising

alternatives to conventional fossil-based plastics. Their broad application instead of fossilbased plastics is, however, frequently the subject of criticism because of offering limited

environmental benefits. The study presents a comparative life cycle assessment (LCA) of

fossil-based polyethylene terephthalate (PET) versus its recycled and bio-based counterparts. The system boundary covers the plastics manufacturing and end-of-life plastic management stages (cradle-to-cradle/grave variant). Based on the data and assumptions set

out in the research, recycled PET (rPET) demonstrates the best environmental profile out

of the evaluated plastics in all impact categories. The study contributes to circular economy in plastics by providing transparent and consistent knowledge on their environmental

portfolio.

Abstract

Municipal waste is a global issue and they are generated in all countries around the world. Both in the European Union and the United States, a common method of non-recyclable waste utilization is thermal incineration with energy recovery. As a result of this treatment, residual waste like bottom ash, air pollution control residues and fly ashes are generated. This research shows that residues from waste incineration can be a potential source of critical raw materials. The analysis of the available literature prove that the residues of municipal waste incinerators contain most of the elements important for the US and EU economies. Material flow analysis has shown that each year, the content of elemental copper in residues may be 29,000 Mg (USA) and 51,000 Mg (EU), and the amount of rare earth elements in residues exceeds their mining in the EU. In the case of other elements, their content may exceed their extraction by even over 300%. The recovery of elements is difficult due to their encapsulation in the aggregate matrix. The heterogeneous nature of residues and the many interactions between different components and incineration techniques can make the process of recovery complicated. Recovery plants should process as much of the residues as possible to make their recovery profitable. However, policy makers from the EU and the US are introducing new legal regulations to increase the availability of critical raw materials. In the EU, new regulations are planned that will require at least 15% of the annual consumption of critical raw materials to come from recycling. Therefore, innovative technologies for recovering critical raw materials from waste have a chance to receive subsidies for research and development.

Abstract

In recent years, there has been a marked increase in the amount of municipal waste generated in Poland. In 2020, 21.6% of all municipal waste was subjected to a thermal treatment process. Consequently, the amount of ashes generated is significant. Due to their properties, it is difficult to utilize this type of waste within concrete production technology. One of the waste utilization methods is to add it to hardening slurries used in, among others, cut-off walls. The article assesses the possibility of using ashes from municipal waste incineration as an additive to hardening slurries. It also discusses the technological properties of hardening slurries with the addition of the ashes in question. The experiment showed that it is possible to compose a hardening slurry based on tested ashes with technological properties suitable for use as a cut-off wall. Further research directions were proposed.

Abstract

The paper presents an application of Life Cycle Assessment (LCA) method for the environmental evaluation of the technologies for the fertilizers production. LCA has been used because it enables the most comprehensive identifi cation, documentation and quantifi cation of the potential impacts on the environment and the evaluation and comparison of all signifi cant environmental aspects. The main objective of the study was to assess and compare two technologies for the production of phosphorus (P) fertilizers coming from primary and secondary sources. In order to calculate the potential environmental impact the IMPACT 2002+ method was used. The fi rst part of the LCA included an inventory of all the materials used and emissions released by the system under investigation. In the following step, the inventory data were analyzed and aggregated in order to calculate one index representing the total environmental burden. In the scenario 1, fertilizers were produced with use of an integrated technology for the phosphorus recovery from sewage sludge ash (SSA) and P fertilizer production. Samples of SSA collected from two Polish mono-incineration plants were evaluated (Scenario 1a and Scenario 1b). In the scenario 2, P-based fertilizer (reference fertilizer – triple superphosphate) was produced from primary sources – phosphate rock.

The results of the LCA showed that both processes contribute to a potential environmental impact. The overall results showed that the production process of P-based fertilizer aff ects the environment primarily through the use of the P raw materials. The specifi c results showed that the highest impact on the environment was obtained for the Scenario 2 (1.94899 Pt). Scenario 1a and 1b showed the environmental benefi ts associated with the avoiding of SSA storage and its emissions, reaching -1.3475 Pt and -3.82062 Pt, respectively. Comparing results of LCA of P-based fertilizer production from diff erent waste streams, it was indicated that the better environmental performance was achieved in the scenario 1b, in which SSA had the higher content of P (52.5%) in the precipitate. In this case the lower amount of the energy and materials, including phosphoric acid, was needed for the production of fertilizer, calculated as 1 Mg P2O5. The results of the LCA may play a strategic role for the decision-makers in the aspect of searching and selection of the production and recovery technologies. By the environmental evaluation of diff erent alternatives of P-based fertilizers it is possible to recognize and implement the most sustainable solutions.

Abstract

Energy production from renewable sources is one of the main ways to fight against global warming. Anaerobic digestion process can be used to produce biogas containing methane. In the light of the growing demand for substrates, a variety of raw materials are required. These substrates should be suitable for anaerobic digestion, and processing them need to provide the desired amount of energy.
This paper aims to discuss the agricultural biogas market in Poland, its current state, and the possibility of development during energy transformation, in particular in terms of using waste as a substrate for energy production. In February 2022, there were 130 agricultural biogas plants registered in Poland. On the other hand, in 2020, 4,409,054.898 Mg of raw materials were used to produce agricultural biogas in Poland. Among all the substrates used, waste played a special role.
With the right amount of raw materials and proper management of a biogas plant, it is possible to produce electricity and provide stable and predictable heat supply. Bearing in mind the development of the Polish and European biogas markets, attention should be paid to ensure access to raw materials from which chemical energy in the form of biogas can be generated. Due to limited access to farmland and the increasing demand for food production, one should expect that waste will be increasingly often used for biogas production, especially that with high energy potential, such as waste related to animal production and the meat industry.
