Volume Of Waste Research Articles

A review on European sustainable practices in end-of-life vehicles management.

The management of end-of-life vehicles (ELVs) has become a significant environmental and economic challenge due to the substantial volumes of hazardous waste generated. This article analyses sustainable practices in ELV management across Europe, with a focus on contributions to the circular economy. The systematic literature review, conducted for articles published in the period 2016-2024, identifies five topics: (1) policy and regulatory frameworks evaluations and suggestions; (2) economic and environmental benefits through optimization modelling; (3) trends and performances analysis; (4) advanced treatment technologies and their impact and (5) economic and environmental impacts assessments. The findings highlight the importance of state-of-the-art recycling processes and coordinated stakeholder efforts in improving ELV management outcomes. In addition, the correlation between ELVs recycling and gross domestic product (GDP) was analysed. Data analysis for 27 European countries in the period 2016-2021 shows a moderate correlation. Specifically, countries with stronger economies tend to produce more ELVs, distinguishing two clusters when GDP is 35,000 € per capita. By adopting best practices and innovative approaches, European countries can enhance their ELV management systems, support a more circular economy and sustainable development. This work highlights the possible correlation between GDP per capita and ELV recycling rates across the European Union, the identification of economic clusters, and the critical role that advanced recycling technologies play in improving sustainability.

CIRCULAR ECONOMY IN PHOTOVOLTAICS: AN ANALYSIS OF GLOBAL REGULATIONS AND THEIR IMPLICATIONS IN BRAZIL

As the market expands, the volume of waste generated by this sector is also growing. However, in many countries, regulations for the management of this waste at the end of its useful life are still inadequate, partly because the amount of solar modules discarded to date has been relatively low. This study reviews the value chain of solar photovoltaic energy, focusing on the analysis of regulations aimed at the management of photovoltaic waste at the end of its useful life, both at the national and international levels. To this end, a bibliometric review was conducted that analyzed 654 peer-reviewed articles published in English. The results provide an overview of the global regulations and standards applied to the treatment of photovoltaic waste, providing useful information for entrepreneurs and policy makers in evaluating future photovoltaic technologies and in the creation of guidelines for the management of this waste.

Matrizes cimentícias com o uso de resíduos de construção e demolição para redução do impacto ambiental de blocos de pavimentação

The construction industry is responsible for the intensive consumption of natural resources and the generation of large volumes of construction and demolition waste (CDW), which are often disposed of improperly. This research developed concrete blocks using recycled CDW aggregates, promoting sustainability and circular economy by reusing these materials in urban infrastructure. Waste was collected from a recycling plant over five months, selecting Brita 1, Brita 0, and Pó de Brita to compose the concrete mixes. Particle size distribution, bulk density, and specific gravity tests were performed, and blocks and specimens were molded with 100% replacement of natural aggregates by CDW. The compressive strength tests were carried out at 14 and 28 days, while the abrasion test was performed only at 28 days. X-ray fluorescence (XRF) and Scanning electron microscopy (SEM) were used to characterize the products. The results indicated a compressive strength of 34.3 MPa at 28 days, close to the minimum required by the standard (35 MPa). XRF analysis showed a predominance of SiO₂, CaO, Al₂O₃, Fe₂O₃, MgO, SO₃, and K₂O oxides, all within normative limits. Leaching and solubilization tests, conducted according to NBR 10005 and NBR 10006, classified the waste as non-hazardous and non-inert. This study demonstrates that using CDW in concrete block production is a viable and sustainable alternative, contributing to waste reduction, material reuse, and the development of sustainable urban infrastructure.

Mengorganisir Sampah yang Tercemar di TPS Masyarakat Dusun Karanglangon Desa Leran Wetan Kecamatan Palang Kabupaten Tuban

Waste is leftover material that is considered to have no economic value, but its existence cannot be avoided in people's social life. In Karanglangon Hamlet, the increase in population that occurs every year increases the volume of waste produced. As the population increases, household waste production and other activities also increase, thereby exacerbating waste management problems in the region. If not managed properly, the increasing amount of waste can have various negative impacts, both on public health and the surrounding environment, such as air, land and water pollution. This problem demands more attention from various parties to find appropriate and sustainable solutions. This research aims to identify in more depth the problems related to waste management at the Dusun Karanglangon TPS using the PAR (Participatory Action Research) approach method. The research results revealed that the condition of the waste at the TPS had a significant negative impact on the surrounding environment. The main causes are limited facilities, minimal budgets, and inadequate waste management standards, resulting in the accumulation of waste and increasingly severe environmental pollution.

Students’ Perception Towards Solid Waste Management and Environmental Sustainability of Nnamdi Azikiwe University Campus, Awka

Nigeria’s rising population makes waste generation an inevitable endeavour. In the journey of national development, waste generation is static. With a population of over 170 million, Nigeria produces a staggering volume of solid waste, of which less than 20% is collected through a formal system. Waste generation on the Nnamdi Azikiwe University campus, Awka, has remained contentious as generated waste is neither categorised nor recycled for re-usage purposes. The survey research method was adopted for this research, with the questionnaire utilised as research instrument. This study included the entire population due to size manageability. Statistically, descriptive and inferential statistical analyses were fit for purpose and, hence, utilised. Findings revealed that biological processing of waste and environmental waste management education would result in the environmental sustainability of the Nnamdi Azikiwe University campus, Awka. This study recommends that the university management prioritise building a biological waste processing facility and champion the creation of environmental waste management education awareness for improved harmful waste generation and control.

Supply Chain Design for Waste Valorization Through High-Energy-Density Pellet Production in Chile

This study presents the development and application of a mathematical optimization model to improve decision-making in the supply chain for high-energy-density pellet (HEDP) production and commercialization. Focused on the Metropolitan Region of Chile, the research involved a detailed analysis of key supply chain components, including identifying landfills and controlled dumps, waste volume assessments, plant location analysis, technology evaluation, and market potential exploration. The model revealed that the available raw material in the region was sufficient to meet 100% of HEDP demand, with a surplus of 2,161,952 tons remaining after satisfying maximum demand. An optimization analysis of potential plant locations identified Santa Marta as the optimal choice, resulting in annual cost savings of USD 100,000 compared to other sites. This work underscores the role of mathematical optimization in enhancing supply chain efficiency for biomass-based energy products, offering valuable insights for strategic decision-making in similar contexts.

An assessment of household solid waste management in Mainpuri, Uttar Pradesh, India

<p>Rapid industrialization, urbanization, population growth, and migration from rural areas have resulted in increased solid waste generation in developing cities, which is commonly regarded as the most significant urban issue. The improper disposal of waste and inefficient collection methods is a significant problem in most of the municipalities in Indian cities. This challenge is further compounded by unscientific waste treatment practices, lack of modern technology, and limited resources. This study aims to assess the status of solid waste generation and disposal across different household income groups and to evaluate how Mainpuri manage and handles the solid waste management system. The study is based on primary data collected through a household survey in Mainpuri city, covering a sample of 1,836 households from various income groups. The data used in this assessment was collected from household surveys and government records. Although there is a recycling plant in operation, its capacity is inadequate to address the increasing waste generation and demands of the community. This shortfall underscores the need for enhanced waste management strategies and infrastructure to effectively cope with the rising volumes of solid waste. As a result, large quantities of solid waste accumulate in low-lying areas near the Isan River and the proximity of the plant. Without a comprehensive solid waste management plan in the municipality, the situation is likely to deteriorate further. Mainpuri City urgently needs a sustainable strategy to effectively manage its solid waste, addressing both current challenges and future demands. Implementing such a strategy is essential for improving public health, environmental conditions, and overall quality of life in the city.</p>

Melt Spinnability Comparison of Mechanically and Chemically Recycled Polyamide 6 for Plastic Waste Reuse.

With the increasing volume of synthetic fiber waste, interest in plastic reuse technologies has grown. To address this issue, physical and chemical recycling techniques for polyamide, a major component of textile waste, have been developed. This study investigates the remelting and reforming properties of four types of pristine and recycled polyamide 6, focusing on how the microstructural arrangement of recycled polyamides affects polymer fiber formation. DSC and FT-IR were used to determine the thermal properties and chemical composition of the reformed thin films. Differences in the elongation behavior of molten fibers during the spinning process were also observed, and the morphology of the resulting fibers was examined via SEM. Birefringence analysis revealed that the uniformity of the molecular structure greatly influenced differences in the re-fiberization process, suggesting that chemically recycled polyamide is the most suitable material for re-fiberization with its high structural similarity to pristine polyamide.

The chlorination and separation of aluminum using low-temperature sulfur chloride reagents

ABSTRACT There is currently no strategy for the permanent waste disposal or recycling for used nuclear fuels from research reactors. For this reason, low-temperature reactions have been developed for the chlorination of the Al alloys and subsequent separation from used nuclear fuels to reduce the volume of high-level waste in storage. Three sulfur chloride reagents – S2Cl2, SOCl2, and SO2Cl2—were tested, and two were found to quantitatively chlorinate Al metal and Al alloys under mild conditions. These low-temperature reactions proceed between 298 and 411 K, and up to 5 g of metal is chlorinated in 1–3 h. Preliminary results indicate that the reactivity and exothermicity of the reaction between the Al and sulfur chloride reagents is highly dependent on the surface area-to-volume ratio of the metal and the volume of solvent. Elemental S is produced as a by-product during the chlorination with S2Cl2 but can be quantitatively rechlorinated under mild conditions to regenerate the initial chlorination reagent. Therefore, in this case, chlorine is the only element consumed in the reaction, thus minimizing the waste generated during the chlorination process. The AlCl3 may then be separated from other materials present in Al 6061 or Al 8001 because of its high solubility in the sulfur chloride reagents. This process may also be extended to chlorinate Al from research reactor fuels.

ASSESSMENT OF THE PROBABILITY OF OCCURRENCE OF EMERGENCY SITUATIONS DURING OPERATION OF THE PYROLYSIS PLANT

The article discusses the issues of reliability and safety of operation of a pyrolysis plant for the disposal of used tires, which, in the context of an increasing volume of waste and the need for their effective disposal, is an urgent topic. The problem statement is related to the identification of factors affecting the reliability of the installation and the development of methods to prevent emergencies.The purpose of the study is to analyz the reliability of the pyrolysis plant and develop recommendations for its improvement. To achieve this goal, the causes and probabilities of failures of system elements are investigated, an analysis using the failure tree method is carried out. This method made it possible to identify the weaknesses of the system and assess the probability of their failures, which is critical to prevent emergencies.An assessment of the reliability of the installation showed that the greatest contribution to the probability of accidents is made by a malfunction of the gas separation system. This element is the most vulnerable due to its complexity and importance in the pyrolysis process, as it is responsible for the safe and effective separation of pyrolysis products. Any malfunction of the gas separation system can lead to the accumulation of dangerous gases, increasing the risk of explosions and fires. The identified emergencies require special attention to the development of effective measures to minimize them.The article proposes methods to improve the reliability of the system, the main of which is the redundancy of the most vulnerable elements. This will significantly reduce the probability of failures and increase the overall reliability of the installation. In addition, it is recommended to carry out regular inspections and maintenance of all elements of the system. These measures will help to identify and eliminate potential malfunctions in a timely manner, which will significantly reduce the likelihood of failures that can lead to emergencies.Thus, ensuring the reliability and safety of a pyrolysis plant for the disposal of used tires requires an integrated approach. Enabling redundancy of vulnerable elements and regular maintenance will minimize the likelihood of failures that can lead to emergencies and guarantee stable and safe operation of the system. These measures will not only increase the efficiency of disposal, but also ensure reliable and long-term operation of the installation.This article focuses on the importance of identifying vulnerable elements of the system and conducting regular maintenance to improve the reliability and safety of operation of the pyrolysis plant.

Regional Framework Towards Establishing Treatment, Storage, and Disposal (TSD) Facilities for PV Waste Management in the Philippines: A Case Study of Laguna Province

Abstract. The accelerated adoption of photovoltaic (PV) systems for renewable power generation in the Philippines will yield a tremendous amount of PV waste. However, the country lacks a comprehensive framework for understanding PV module waste volume growth and optimally siting Treatment, Storage, and Disposal (TSD) facilities for PV waste management based on minimum siting factor. The study aims to develop a regional framework that utilizes a geographic information system (GIS)-based approach to find the potential sites and optimal locations of TSD facilities in Laguna, Philippines, based on the estimated PV module waste growth of solar energy systems with service contracts and minimum siting criteria under Department of Environment and Natural Resources (DENR) Administrative Order 2013-22. By 2060, the projected amount of PV module waste in Laguna province will be around 162,230 metric tons based on the waste projection results. The suitable sites cover around 19,720.5 hectares or 11.21% of the total land area of Laguna, which were determined by various siting factors that encompass social, economic, and environmental factors and obtained using binary suitability analysis and vector overlay analysis. The optimal locations of the two TSD facilities were identified using strategic positioning based on hotspot analysis, clustering algorithm, and proximity analysis. Consequently, the distance and GHG emissions of the two optimal locations were calculated. Indeed, the approach will serve as a guide for policymakers and other stakeholders in understanding PV module waste growth and strategically and optimally position TSD facilities on suitable sites for efficient and effective PV waste management.

Enhancing mortar performance: A comparative study on particle size of recycled concrete powder and metakaolin in binary and ternary blends

The construction industry generates substantial volumes of construction and demolition waste (CDW), including aggregates and fine particles classified as recycled concrete powder (RCP). This study investigates the sustainable reuse of RCP by evaluating its combined use with metakaolin (MK) as supplementary cementitious materials in both binary and ternary mixtures with Portland cement, aiming to reduce environmental impact without compromising mortar performance. The experimental program assessed two particle sizes of RCP, along with MK, and various replacement levels, which were pivotal parameters in the study. A series of binary and ternary mixtures were prepared with different proportions of RCP and MK, considering replacement levels ranging from 10 % to a maximum of 30 %, using RCP alone or in conjunction with MK. The mortars were analyzed in both fresh and hardened states, focusing on critical properties such as consistency index, compressive strength, splitting tensile strength, elastic modulus, water absorption, density, void index, and capillary water absorption. Furthermore, a microstructural analysis was conducted using scanning electron microscopy (SEM), and a cement consumption efficiency index, along with CO₂ emissions data, was calculated to provide a comprehensive evaluation of performance and sustainability. The findings demonstrate that RCP with a particle size comparable to that of cement (RCP1) significantly enhances both physical and mechanical performance, particularly in ternary mixtures with MK due to its pozzolanic activity, where the silica (SiO₂) and alumina (Al₂O₃) components react to form additional hydrated products, thereby improving the properties of mortars. For instance, the ternary mixture comprising 15 % RCP1 and 15 % MK attained compressive and splitting tensile strength of 29.26 MPa and 3.36 MPa at 28 days, respectively, compared to the reference mixture, which yielded 27.96 MPa and 3.33 MPa. Conversely, larger particle sizes (RCP2) and higher replacement levels led to a decline in performance across all evaluated parameters. Ternary mixtures containing RCP1 also exhibited a higher cement consumption efficiency index and lower CO₂ emissions per MPa. Notably, the mixture with 15 % RCP1 and 15 % MK showed the most favorable indicators overall, with cement consumption and CO₂ emissions measured at 12.08 kg/m³·MPa and 10.01 kgCO₂/m³·MPa, respectively. These results suggest that the synergy between RCP1 and MK enhances particle packing and matrix density, which in turn improves the structural properties of the mortar. The incorporation of MK compensates for the limited reactivity of RCP, especially at higher replacement levels, while the utilization of RCP1 offers significant sustainability benefits by reducing Portland cement consumption. This study demonstrates that the combination of RCP and MK in ternary mixtures presents a technically viable and sustainable alternative for mortar production, optimizing cement use and reducing CO₂ emissions. The innovative application of CDW-derived RCP in construction materials represents a practical approach to promoting more sustainable practices within the industry.

Treatment of Leachate Obtained in Leiras de Compostagem de Remos de Alimentos (Composting of Food Remains) by Anaerobic Biodigestion Followed by Oxygenation: a Case Study in the Federal District

Objective: During the composting process of organic waste, the leachate from the degrading windrows requires treatment processes due to its significant load of polluting substances. Frequently, the approach adopted to treat leachate involves a combination of different processes. This study aimed to evaluate the performance of a biological treatment system, consisting of anaerobic digestion followed by oxygenation, applied to leachate from a composting company of organic waste obtained from residential and commercial kitchens located in the Federal District. The outlined hypothesis is that anaerobic treatment followed by oxygenation, with the material studied and under the experimental conditions, allows for the attainment of material with characteristics that permit its discharge into water bodies, according to CONAMA Resolution No. 430/2011, which complements and amends Resolution No. 357/2005. Method: The leachate was collected from the windrows through pipes and directed to a physical treatment system composed of a sand and grease trap. After that, it was pumped into two anaerobic reactors operating in sequence, with a total retention time of 15 days. The material was then directed to a waterproof masonry tank with natural and forced aeration. Samples were taken before and after the treatment of the leachate for the determination of electrical conductivity, temperature, pH, chemical and biochemical oxygen demands, total dissolved solids, total and volatile solids, total nitrogen, N-NH4+, N-NO3-, N-NO2-, total alkalinity, total phosphorus, thermotolerant coliforms, and Salmonella. Results and Discussion: The absence of Salmonella was observed in both the samples obtained before and after the treatment. Reductions in electrical conductivity (7.6%), temperature (16.2%), total alkalinity (23.0%), chemical oxygen demand (42.3%), biochemical oxygen demand (45.5%), total nitrogen (9.3%), N-NH4+ (18.4%), total phosphorus (30.1%), total solids (16.9%), total dissolved solids (14.0%), volatile solids (21.5%), and thermotolerant coliforms (99.9%) were observed after treatment. On the other hand, increases in pH (12.3%), N-NO3- (30.4%), and N-NO2- (14.4%) were noted. However, the material treated under the experimental conditions adopted did not meet the environmental discharge requirements established by Brazilian legislation (CONAMA Resolution 430/2011), especially for the parameters biochemical oxygen demand, total nitrogen, N-NH4+, total phosphorus, N-NO₃⁻, N-NO₂⁻, and thermotolerant coliforms. Research Implications: The volume of organic waste collected and treated by composting has been increasing in recent years in Brazil, especially due to legal requirements at state (district) and municipal levels. Since organic waste generally has high moisture content, a large volume of leachate from the windrows is produced and can become a significant source of environmental contamination. Biological treatments such as anaerobic digestion followed by aeration can be an important tool to prevent this contamination, but chemical and biochemical parameters, as well as conditions like retention time, need to be evaluated to verify the efficiency of treatment systems.

Renewable energy waste recycling

Broad field of technologies is related to the countries’ green hydrogen goals, with renewable energy technology (RE) being a significant part. RE’s ability to support green hydrogen industry is now being hindered by the waste issue. By 2050, the world will have accumulated up to 60–70 million tons of waste photovoltaic (PV) modules, 43.4 million tons of wind turbine blades and up to 1 million tons of lithium batteries. Existing technologies and recycling capacities are not capable of recycling these volumes, since the readiness levels of most of the applicable technologies is assessed as TRL3 - TRL8 and their economic efficiency is below the profitability level. The purpose of this work is to substantiate the need and calculate the amount of state support for the development of RE waste recycling technologies. It has been determined that the sum of economic losses in the absence of recycling by 2050 will amount to up to 215 billion dollars, including in the RE leading regions: in China 81 billion dollars, in the EU 42 billion dollars, in the USA 26 billion dollars. The regional distribution of waste volume is presented, grouped by energy price level: 30% of waste in countries with the highest energy tariffs, mainly in Europe, 20% in regions with an average price, including all of North America, 50% in regions with the lowest price - most Asian countries. The dynamics of the increase in the number of patents for the selected IPCs for the period 2000–2024 was obtained, and the leading countries were identified. It is shown that the effect of state support for recycling will be obtained in three industries: firstly, a cost-effective industry for recycling renewable energy waste will be formed, secondly, the availability of scarce materials for renewable energy producers will increase, and thirdly, unconstrained RE deployment will back the green hydrogen development. The timeframe of the countries’ hydrogen goals and the RE waste accumulation trends jointly indicate the urgency of the waste issue, when the analysis proves the reasonable request for the state involvement.

Closed-loop supply chain design considering quantity-dependent price and decentralized local waste management

With the increasingly widespread use of household plastic products, environmental pollution caused by plastic waste has emerged as a severe problem. Despite the efforts of academia and government bodies, plastic recycling rates worldwide remain low. Thus, this study aims at establishing a closed-loop supply chain design model for household plastic recycling. We develop a bilevel optimization model to reflect decentralized decision-making between a manufacturer and public sectors and propose a strategy to obtain optimal solutions. The proposed model considers two critical aspects of the problem: decentralized local waste management and quantity-dependent price. Numerical experiments are conducted based on real annual operation data, and various managerial insights are derived from sensitivity analyses. Additionally, we recommend various strategies to mitigate potential social conflicts arising from increasing volumes of plastic waste as well as directions for government policy aimed at enhancing the plastic recycling rate.
