Ultrasound-assisted efficient and convenient method of extracting valuable metals (Ni, Co, and Cd) from waste Ni–Cd batteries using DL-malic acid

Recycling waste Ni–Cd batteries has received much attention recently because of the serious environmental pollution they cause and to avoid the dissipation of valuable metals. Despite significant research, it is still difficult to efficiently recycle valuable and hazardous metals from waste Ni–Cd batteries in an economical and environmentally friendly manner. This study employed a novel process utilizing ultrasound-assisted leaching to recover Ni, Cd, and Co from waste nickel-cadmium (Ni–Cd) batteries. Organic DL-malic acid served as the leaching agent and H2O2 was employed as an oxidizing agent. The effects of various factors on the recovery efficiency of Ni, Cd, and Co, such as leaching temperature, time, DL-malic acid concentration, pulp density, H2O2 concentration, and ultrasound frequency, were also examined. To predict the chemical compounds present before and after the recycling experiments, the solid residues from the metal extraction were analyzed using XRD, XPS, FE-SEM, and EDS element mapping. Concurrently, ICP-OES was utilized to determine the metal content in the leachate. Under optimized conditions of 90 °C, 90 min, 2M DL-malic acid, 160 mL/g pulp density, and 20% ultrasound frequency, over 83% of Ni, 94% of Cd, and 98% of Co were effectively leached from the waste Ni–Cd battery powder. The leaching kinetics of Ni, Cd, and Co followed the surface chemical reaction control model. The activation energies (Ea) for Ni, Cd, and Co leaching were 21.34, 20.47, and 18.38 kJ/mol, respectively. The findings suggest that ultrasound-assisted leaching is an efficient, cost-effective, environmentally friendly, and sustainable alternative for extracting precious and hazardous metals from waste Ni–Cd batteries. Additionally, it reduces industrial chemical usage and enhances waste management sustainability.

Lettuce (Lactuca sativa L.) Cultures and the Bioactivity of Their Root Microflora Are Affected by Amended Soil.

This study aimed to highlight the positive effects of various recycled organic substrates on lettuce plants (Lactuca sativa L.) and to promote sustainable waste management practices, contributing to the concept of a circular economy. Over a two-month period, the growth potential and rhizosphere microflora of lettuce plants grown in soil amended with different recycled substrates were investigated. All data were compared, and the effects of the culture substrates were evaluated. All groups containing soil improvers offered a significant increase in the number of leaves per plant and, in two cases, an increase in dry biomass as well as an increase in the concentration of all leaf pigments. Both MDA and H2O2 concentrations were the lowest in two groups containing soil improvers (VG 5% and PLUS 10%). At the end of the culture period, isolation and culture of bacteria from the plant rhizosphere were performed. Different bacterial strains were isolated and tested for the production of antimicrobial agents against six microbial indicators (B. subtilis, E. coli, S. aureus, S. cerevisiae, C. albicans, and P. aeruginosa). The greater percentage of the isolated strains showed an ability to inhibit the growth of the B. subtilis index. Most of the strains with antimicrobial activity were isolated from the soil samples of the plain soil group and the soil amended with the commercial fertilizer. Three of the isolated strains originating from the Ginagro 5% group are multiproducers as they inhibit the growth of three microbial indicators or more.

Anaerobic co‑digestion of bovine ruminal waste and brewery spent grain: Effects of inoculum to substrate ratio, mixing ratio, process stability, organic matter removal, and methane yield

The technological potential of co-digesting bovine rumen waste (BRW) with brewery spent grain (BSG) is significant, offering enhanced biogas production and effective waste management. This study's findings demonstrate that the anaerobic digestion process becomes significantly more efficient when difficult to degrade BRW is combined with easily degradable BSG. The highest methane yield obtained in the mono-digestion of BRW was 127.11 NmLCH4 gVS−1 with biodegradability of 33.89 % in inoculum to substrate ratio (ISR) 2, and for de BSG obtained was 304.18 NmLCH4 gVS−1 with biodegradability of 68.26 % in ISR 4. The overall average obtained in co-digestion for volatile solids (VS) removal was 26.28 %, and the concentration of methane present in the biogas was 57.18 %. The VS removal efficiency and the increase in biogas and methane yield were directly proportional to the rise in ISR and the proportion of BSG in the mixture. Specifically, the ideal mix of 25 % BRW with 75 % BSG at ISR 4 resulted in a notable methane yield of 255.30 NmLCH4 gVS−1. This process stabilizes digestion and significantly improves solids removal and methane concentration, making it a highly efficient solution for sustainable energy production and industrial waste management.

Forecasting End-of-Life Vehicle Generation in the EU-27: A Hybrid LSTM-Based Forecasting and Grey Systems Theory-Based Backcasting Approach

End-of-life vehicle (ELV) forecasting constitutes a crucial aspect of sustainable waste management and resource allocation strategies. While the existing literature predominantly employs time-series forecasting and machine learning methodologies, a dearth of studies leveraging deep learning techniques, particularly Long Short-Term Memory (LSTM) networks, is evident. Moreover, the focus on localized contexts within national or municipal boundaries overlooks the imperative of addressing ELV generation dynamics at an international scale, particularly within entities such as the EU-27. Furthermore, the absence of methodologies to reconcile missing historical data presents a significant limitation in forecasting accuracy. In response to these critical gaps, this study proposes a pioneering framework that integrates grey systems theory (GST)-based backcasting with LSTM-based deep learning methodologies for forecasting ELV generation within the EU until 2040. By introducing this innovative approach, this study not only extends the methodological repertoire within the field but also enhances the applicability of findings to supranational regulatory frameworks. Moreover, the incorporation of backcasting techniques addresses data limitations, ensuring more robust and accurate forecasting outcomes. The results indicate an anticipated decline in the recovery and recycling of ELVs, underscoring the urgent need for intervention by policymakers and stakeholders in the waste management sector. Through these contributions, this study enriches our understanding of ELV generation dynamics and facilitates informed decision-making processes in environmental sustainability and resource management domains.

Development of a System Suitable for an Apartment Complex for the Collective Recovery of Solid Resources from Food Waste: A Study on South Korea

The installation of food waste disposers has been prohibited in South Korea, due to conflicts with governmental policies that are focused on resource recovery from food waste and concerns about potential damage to the city’s sewer system. However, there is a growing demand for such systems in the country. This study proposes a system for the collective recovery of solid resources from food waste tailored for apartment complexes in South Korea, using an innovative solid–liquid separation technology. In the pilot experiment, 49.60% of the solids fed into the system were recovered as solid matter, confirming its practical applicability. Ultimately, a solid resource collective recovery system suitable for the high-rise apartment residence style of South Korea was developed and applied to an actual apartment complex. The final-stage solids were discharged from the system and processed through bio-drying, subsequently exhibiting a combustible material content of 67.06%, higher heating value (HHV) of 4843 kcal/kg, and lower heating value (LHV) of 3759 kcal/kg; moreover, they have the potential to be repurposed as biomass–solid refuse fuel (bio-SFR), compost, feed, and substrate for biogas production. The proposed food waste disposal system not only aligns with governmental policies, but also facilitates the recovery of high-quality resources from food waste, while providing a sustainable waste management solution.

Environmental impacts of food packaging: Is it all a matter of raw materials?

The packaging sector and the environmental impacts stemming from its various materials and applications are currently at the forefront of scientific and political debate. To estimate the environmental impacts associated with raw materials and identify the role of industrial processes, this study presents a cradle-to-grave Life Cycle Assessment applied to two distinct packaging formulations for chocolate bars, namely oriented polypropylene-based and paper-based packaging. The product systems related to the two alternatives were compared by focusing on the contribution of each resource input and emission of the production phase, to identify respective environmental trade-offs and potentials for future improvements throughout the life cycle. Our study also proposes a laboratory-based approach to develop robust assumptions concerning the modeling of end-of-life material treatment and provide support to decision-making toward environmentally sustainable waste management practices. From the outcomes, a relative preference emerges for paper-based packaging, from a minimum of 10 to a maximum of 16 out of 18 environmental categories, depending on the evaluated scenario. The hotspot analysis highlighted a significant influence of the processing phases, with raw materials being generally characterized by lower percentage contributions to the final impact. In conclusion, the findings underscore the importance of considering the entire life cycle when assessing packaging sustainability. Moreover, the proposed laboratory approach offers valuable insights for policymakers and industry stakeholders to optimize end-of-life strategies and minimize the overall environmental footprint of packaging materials.

The influence of the pre-addition of semi-dry and dry slaked lime during the purification of flue gas on the subsequent chelation and solidification treatment of MSWI fly ash

Incineration is a main way to dispose the municipal solid waste (MSW) in China, but municipal solid waste incineration (MSWI) fly ash will negatively impact the environment and human health as containing high content of heavy metals. This study aimed to investigate the influence of the pre-addition of dry/semi-dry slaked lime during the purification of flue gas on the subsequent chelation and solidification treatment of fly ash. This study has found that semi-dry slaked lime had more effect on the solidification rate of heavy metals in MSWI fly ash compared to the pre-addition of the dry slaked lime. As the dosage of semi-dry slaked lime increased, the solidification rate of Zn and Ba increased to 100 %, while the solidification rate of Cr decreased to as low as 0 %. However, the effect of the dosage of semi-dry slaked lime on the other heavy metals (Cu, Pb, Cd, Ni) showed a complex trend. This study underscores the importance of the pre-addition of slaked lime during the purification of flue gas in influencing subsequent chelation and solidification treatment of MSWI fly ash. It provides valuable insights into optimizing lime dosage to enhance heavy metal stabilization, contributing to more effective and sustainable waste management practices.

Abundance and distribution of anthropogenic marine litter on the beaches of Sonadia Island: An Ecologically Critical Area

Plastic is one of the most common types of anthropogenic marine litter (AML) found in the world's oceans. Plastic entry into marine ecosystems poses a significant threat to marine ecology. Its ubiquitous prevalence creates serious environmental concerns. To address this issue, a comprehensive survey was conducted on the seven beaches of Sonadia Island, designated as an ecologically critical area of Bangladesh. The research aimed to investigate the abundance and distribution of AML and assess environmental health using four indices. A total of 14809 AML items were collected, yielding an average density of 0.71 items/m². The most abundant AML types were plastic (76.41 %), with a mean density of 0.49 items/m². Fishing and recreational activities are identified as the primary sources of AML on Sonadia Island. The Clean Coast Index revealed that two beaches had ‘moderate cleanliness’, four were ‘dirty’, and one was ‘extremely dirty’. The Plastic Abundance Index indicated ‘moderate abundance’ with a mean value of 2.97. Furthermore, the Hazardous Item Index classified four beaches under ‘class II’, and three were ‘class III’. Additionally, the Pollution Load Index calculated at 21.34 signifies a ‘hazard level III’, denoting high contamination with AML. The results indicate that Sonadia Island's beaches are heavily polluted with AML, particularly plastic, causing significant harm to the local flora and fauna. The research emphasizes the importance of raising awareness about the harmful effects of AML on marine biodiversity. To address this issue, Governments, private organizations, plastic producers and the local community must adopt sustainable waste management practices.

Transforming waste to wealth: Impact of food waste‐derived soil amendments and synthetic nitrogen fertilizer on soil dynamics

AbstractApproximately one‐third of all food produced globally goes to waste, highlighting the need for sustainable waste management technologies like composting and anaerobic digestion. These technologies convert food waste into soil amendment products such as compost, liquid digestate (LD) and solid digestate (SD). However, these food waste‐derived soil amendments have relatively low nutrient contents compared with synthetic nitrogen (N) fertilizers such as urea, making their agricultural use challenging. Despite this, food waste‐derived soil amendments can enhance the physical and biological properties of soil, potentially creating synergistic effects when combined with synthetic N fertilizers. This study aimed to investigate effects of food waste‐derived amendments in soil applied at 50 kg ha−1 total N (compost, LD or SD) and synthetic N fertilizer [urea ammonium nitrate (UAN)] at 50 and 100 kg ha−1 total N. Over 56 days of soil incubation, greenhouse gases (CO2, N2O), soil chemistry (–N, –N, pH) and microbial biomass C (MBC) were measured. Results showed that LD + UAN 50 reduced cumulative N2O emissions by 23% compared with UAN 100, despite having the same total N and similar available N rate applied to soil. Replacing UAN with LD in farming practices can supply equivalent available N while lowering N2O emissions, offering a sustainable nutrient strategy. Moreover, applying food waste‐derived soil amendments can enhance N retention in soils, reducing the need for increased applications of synthetic N fertilizers to compensate for N deficits in farming. Food waste‐derived soil amendments can also act as a slower N release compared with UAN, reducing nitrogen run‐off. SD had the highest CO2 emissions, followed by LD and compost. SD + UAN 50 increased MBC levels because of higher carbon content and labile carbon, and available N because of the application of UAN. The major drawback of using SD compared with LD is that the process of evaporating LD to form SD causes high ammonia volatilization (ammonium in solution into ammonia gas) rates, reducing the available N in SD. Therefore, future studies should explore strategies to reduce ammonia volatilization of LD.

Towards a sustainable supply chain: contribution to hospital waste management in an Algerian hospital

The object of research is medical waste management. Healthcare activities protect health, cure patients and save lives. However, they generate waste that is harmful to public health and the environment. As a result, the management of this healthcare waste is becoming increasingly important in the field of public health and the environment. One of the most problematic places is, poor management of these issues that can put healthcare workers, medical waste workers, patients and their families, and the entire population at risk. On the other hand, poor treatment or inadequate disposal of this waste can also cause risks. From now on, the rational elimination of this pollution is one of the essential conditions for respecting hygiene rules, not only inside establishments, but also in the general environment. In this unfavorable context, we are trying through this contribution to achieve adequate management using reverse logistics practices with the main objective of resolving healthcare waste management problems while taking into account the reality of things in situ. For this purpose, an approach guided by data, carried out directly in the field, by direct contact with the different categories of health personnel interviewed, through findings, observations, audits, questionnaire and knowledge of the causes was used. This approach is based on the audit of compliance with the supply chain in the management of hospital waste in the different departments of the Constantine University Hospital (Algeria). As a result of the research it is shown that the situation is very poor given that the logistics chain is completely faulty or no step is respected. Thus, the least respected stage is storage, where no service exceeds 25 %, this is due to the fact that no clinic has an intermediate waste storage area. And the most respected is treatment stage that does not exceed 75 %. This allowed to detect the inadequacies recorded at the level of the study establishment, and even improvements are suggested for sustainable management of healthcare waste at the level of Algerian health establishments.

By exchanging information and sharing best practices, countries in the region can apply tried and tested solutions. The document aims to promote enhanced regional cooperation as a catalyst for sustainable environment and waste management.

Integrated Waste Management Place and Environmental Pillar Sustainable Development Goals: Solution or Threat?

This article discusses the issue of the Kesiman Kertalangu Integrated Waste Management Site (TPST) which has an impact on the surrounding community because the smoke produced causes disruption to people's sense of smell and even threatens public health, but basically the community is not protesting regarding the existence of the TPST but rather the impact caused by its activities. This article uses a normative legal research method, by taking a statutory approach, then the data collected will be processed using a qualitative approach and explained descriptively. The Kesiman Kertalangu TPST violates the right to a clean and healthy environment as mandated by the constitution, UUPPLH and the Sustainable Development Goal's concept. It is hoped that the government's responsibility regarding the impacts that occur will refer to article 54 UUPPLH and 82 of the Job Creation Law, then the Kertalangu TPST must have an SDG concept, especially Village SDGs, guided by Village SDG number 3, environmental restoration efforts must be made based on UUPPLH and the Job Creation Law. and carrying out sustainable waste management based on SDG's principles as well as developing technology is very necessary in solving problems by comparing it with waste management in Singapore, namely processing smoke from combustion into electrical power and scarp metal which produces high economic value.

WASTE MANAGEMENT IN THE CONCEPT OF GREEN RECONSTRUCTION OF ECONOMY

The article defined the concept of waste management in the environmental management system. The research analysed the problems of waste management in the environmental management system from point of view by a number of domestic and foreign scientists. As a result, authors outlined the basic components of waste management: strategic planning, prevention of environmental pollution, conservation of resources, minimization of the amount and toxicity of waste generation, choosing the best prevention option, assessment of effects and consequences, decision-making. The research described the system of green reconstruction of economy and formed the basic principles of the green post-war reconstruction that would provide sustainable economic development. The article outlined the concept of post-war green reconstruction which should focus on such areas as: sustainable construction and resource saving; implementation of renewable energy sources; sustainable development of infrastructure; implementation of a waste management system, minimization of residues. The authors grounded five main stages of waste management process under post-war reconstruction of Ukraine: prevention of waste generation, preparation for reuse, processing, other uses, disposal. Sustainable waste management solutions are essential to maintain environmental harmony but, also, they are linked with cost, public response, political constraints, and social norms. Consumers' environmental awareness influence the demand for goods and services and thus reduce the amount of waste. Research argued that local communities should developed own waste prevention strategies and attract environmentally conscious businesses to their territory. State policy should focus consumers for preferring products in packaging/container that is suitable for recycling or reuse (glass), paper bags, eco-bags, used appliances.

PRODUCTION OF VALUE-ADDED BIOCHAR AND BIO-OIL FROM MICROWAVE CO2 PYROLYSIS OF MEDIUM-DENSITY FIBERBOARD WASTE

This study investigates the feasibility of using microwave CO2 pyrolysis to dispose of medium-density fibreboard (MDF) waste, a significant by-product of the furniture manufacturing industry. The primary goal is to transform MDF waste into valueadded biochar and bio-oil, exploring an alternative to conventional pyrolysis methods that typically use nitrogen (N2) as a purge gas. The research emphasises the potential benefits of CO2 utilisation in pyrolysis, both to enhance the quality of biochar and bio-oil and as a strategy for greenhouse gas (GHG) mitigation. This research reveals that conducting microwave pyrolysis in a CO2 atmosphere increases biochar (up to 44.8%) and bio-oil (up to 21.2%) yields over N2 pyrolysis. CO2 hinders volatile thermal cracking and aids in gas defragmentation and repolymerisation, with biochar yield rising with time and biooil peaking at an optimal duration. This study underscores microwave CO2 pyrolysis as a promising alternative for converting biomass waste into valuable products, potentially contributing to fuel utilisation. It also highlights the environmental benefits of this method, particularly in terms of CO2 utilisation, aligning with the broader objectives of sustainable waste management and renewable energy production. The findings provide a basis for future research in this area, focusing on optimising process parameters, exploring potential applications of bio-products, and assessing the economic and environmental viability of this innovative approach.
