Characterization and analysis of municipal solid waste generated in the semi-urban region of Thanamandi, Jammu and Kashmir (J&K), India: a basis for developing a suitable waste management approach.

Population growth, urbanization, lifestyle changes, and consumption patterns increase waste management problems in Thanamandi town. The waste generation rate in Thanamandi town is expanding, and there is a need for adequate waste segregation, recycling programs, and sorting facilities. Therefore, this study aims to estimate the municipal solid waste (MSW) generation rate in Thanamandi town, including an analysis of its composition. Additionally, statistical methods are used to assess the potential MSW management approaches. A comprehensive methodology has been adopted, including house-to-house waste collection from 25 pre-selected locations, to ensure representation across different income groups. The collected waste was segregated into food, plastic, paper, and textile waste categories, and the moisture content was analyzed using the oven-drying method. Further, it has been observed from the obtained result that 0.44kg per/capita/day of MSW has been generated from the study area. The result shows that vegetable waste contributes the most followed by food waste and plastic. Additionally, the moisture content of the waste ranged between 12% and 76.25%, with high moisture content primarily found in organic wastes. Moreover, interpolation maps created using QGIS highlighted the spatial distribution of waste generation across the town. They showed a strong correlation between vegetable and food waste and paper and plastic waste. Thus, to manage MSW in the study area, a holistic approach to MSW management is necessary to deal with a mixture of Vegetable and Food waste, i.e., organic matter.

Bioconversion of Food Wastes and By-products to Value-added Products: A Comprehensive Review

Food processing industries are considered to be rapidly expanding sectors due to the increase in the need for food to prevent hunger and the need for nourishing food to support the development of a healthy country. Nowadays, around one-third of the fresh crop is squandered during the food processing chain and is dumped in landfills and the ocean. According to an FAO report, 805 million people worldwide suffer from hunger, yet in 2020, the globe threw away 126 million tons of food waste. High amounts of waste and by products are produced during the manufacturing and processing of food in developing nations, which has a detrimental effect on the environment and is very expensive. It is crucial to turn these food wastes and byproducts into value-added goods for social, environmental, and economic reasons. The 3Rs—Reduce, Reuse, and Recycle—should be adhered to in order to address the problem of food waste in the food sector. Nonetheless, there is a good chance that these biomaterials will be used to create food additives, reducing poverty and malnutrition in the underdeveloped nations where they are generated. Beneficial substances including proteins, fats, carbohydrates, micronutrients, bioactive substances, and dietary fibers can be found in abundance in many of these biomaterials. First, this overview provides brief information on the production of different types of wastes from different processing sectors. Second, the several strategies for managing food waste sustainably as well as the difficulties in implementing these strategies are covered in length here. This review, is an assortment of information pertaining to the recovery of several value-added byproducts, such as biofuel generation, dietary fibers, phytochemicals, bio-preservatives, colorants, and bioactive compounds.

Turning municipal food organic waste into activated carbon: A step towards circular economy

Finding a suitable way of managing the growing problem of municipal organic waste is a pressing issue worldwide. Unsorted municipal food waste (FW) was utilized for the first time as an activated carbon (AC) precursor. Varying pyrolysis conditions such as generation steps and carbonization temperature appeared to have a minor impact on AC characteristics compared to higher activation temperature, particularly 800 °C as indicated by a series of physicochemical characterizations. Selected FW-derived ACs were tested as an adsorbent under different experimental conditions to explore their efficacy in removing methylene blue (MB) from water. The adsorption of MB on FW-derived AC occurred in multilayers on heterogenous surfaces whereas the adsorption of MB on commercial AC occurred on a homogenous surface in a monolayer fashion which can be explained by chemisorption. The maximum MB adsorption by FW-derived AC was 47.72 mg/g under the conditions tested, although results indicated that the adsorption capacity had not been reached. Importantly, the kinetics of MB adsorption onto FW-derived AC was substantially faster than adsorption onto commercial AC. The findings of this study suggest that AC prepared from a diverse mixture of municipal FW is a promising, novel, and cost-effective adsorbent to eliminate MB.

Electrochemical Adsorption-Desorption Mechanism on Composite Electrode Materials for CO2 Direct Air Capturing

Use of carbon-based fossil fuels, greenhouse gases are emitted to the atmosphere causing fatal environmental issues like global warming. To overcome this problem, Sustainable Development Goals (SDGs) is now a fundamental issue for worldwide nations. Among them, carbon neutrality stands as a central pillar since CO2 has the biggest portion of emitted green-house gases. Emitted CO2 from industrial facilities like factories and incinerators is collected by various carbon capturing technology which is developed due to the pursuit of carbon neutrality necessities. Among them, Direct Air Capture (DAC) is gaining interests due to its superior efficiency compared to other alternatives such as filters and absorbents for the challenges like high pressure and elevated temperatures at the CO2 capturing process. Furthermore, the durability of filtration materials and waste problems poses a significant concern to the environment. To overcome these limitations, electrochemical adsorption system is looking forward to becoming the next generation carbon capture technology. By applying varying electrical energies, this allows adsorption and desorption of CO2 within an adsorber layer. By this mechanism, we can significantly reduce the filtration waste of capturing process. The adsorber layer is consisted with catalysts, which has large surface area and active sites that can adsorb and desorb CO2 stably with electricity. Detailed physicochemical and electrochemical characterizations of the reactive and adsorbent materials were conducted with chemically designed evaluation system to measure the CO2 capturing efficiency.

Electrochemical recycling of recycled concrete powder: Selective recovery of calcium and silica to enable sustainable construction materials

Rapid urbanization produces billions of tons of concrete waste annually, with recycled concrete powder (RCP) posing significant challenges due to its high porosity and limited reusability. To overcome RCP’s inherent limitations and maximize resource utilization, we developed a novel “Recycled Concrete Powder Electrolyzer” for selective recovery of key components. This electrochemical method efficiently extracted Ca2＋ ions from RCP, achieving a 96% calcium extraction efficiency comparable to acid leaching. The process produced high-purity portlandite (94% purity; 65.58% yield) with crystal sizes below 30μm, ideal for cement manufacturing, while also recovering fine sand powder and silica-containing products. A Ca(NO3)2 electrolyte enhanced Ca2＋ migration and prevented membrane fouling, resulting in lower energy consumption compared to the NaNO3 system. By converting RCP into a carbon-free cement precursor and recovering valuable components, this approach demonstrates the feasibility of transforming problematic waste into sustainable construction materials. It offers a circular economy solution for concrete waste recycling, reducing landfill burden while providing a low-emission alternative for cement production.

Legal regulation of restriction of use of disposable plastic products in the European Union

The article analyses the problem of plastic waste in the context of transition to a circular economy, which is one of the priorities of the European Union’s policy. The author emphasises the introduction of restrictions on the use of plastic products, starting with Directive 2008/98/EC, which establishes a basic framework for waste management, including plastic, with a focus on recycling and the transition to a circular economy, in order to achieve targets by 2025, 2030 and 2035. The main focus is on Directive 2019/904 on the reduction of the use of single-use plastic products, which aims to reduce the negative impact of plastic on the environment. The Directive provides for a ban on certain types of single-use plastic goods, including plastic lids that must remain attached to containers during use. The article analyses the importance of harmonising the legislation of the EU member states in the process of implementing this Directive, as differences in national laws may lead to legal conflicts. The economic challenges for countries with less developed waste management systems, which may have difficulty meeting the requirements within the established timeframe, are also considered. The article emphasises the need to introduce new technologies and environmentally sustainable consumption patterns to ensure effective implementation of the Directive. Examples of initiatives aimed at reducing the use of single-use plastic, such as the deposit system for plastic bottles in Germany and the Swiss ReCircle programme, are also discussed. Ukraine is also implementing measures to reduce plastic waste, but legislative initiatives need to be further developed to achieve global environmental goals. The article emphasises the importance of raising legal awareness among citizens and businesses for a successful transition to a circular economy.

How do different policy instruments influence circular economy implementation in the construction sector?

ABSTRACT The circular economy (CE) is a promising solution to the growing construction waste and the environmental problems it brings, and government policy instruments are vital for promoting CE implementation. Existing research has been focused on the effects of one or two specific policy tools, like subsidies or fines, on construction CE implementation, which lacked comprehensive comparison among policy instruments and overlooked the stakeholders’ consciousness. There are three policy instruments and each has different characteristics and effects. Therefore, based on the Stimulus–organism–response theory, this study comprehensively explored the impact of the three policy instruments on CE implementation, and the mediating role of contractor intentions was considered. The quantitative questionnaire survey and partial least squares structural equation modelling analysis methods were used to study the relationship between the three policy instruments and CE intention and implementation. Then, the qualitative interview method was adopted to validate the results and provide practical advice. The results provide the government with a policy instrument decision-making framework, which gives a theoretical basis and practical implications for the government and contractor companies in CE implementation and gives insight into releasing construction waste and pollution problems.

Effect of the inclusion complex formation method on the functional properties of poly (butylene adipate co-terephthalate) active films

The food waste and single-use packaging problems require efforts to develop active, sustainable packaging to extend the shelf life of perishable products. Therefore, the β-Cyclodextrin-Clove essential oil inclusion complexes (IC) obtained by ultrasound (IC-U) and kneading (IC-K) methods were incorporated into a PBAT matrix. The effect of the IC on the structural, functional, and biodegradability features of the PBAT matrix was assessed. The results show that the IC exhibited high thermal stability and adequate dispersion in the PBAT matrix during the extrusion process. The PBAT-IC films, as prototypes of packaging bags, improved the shelf life of perishable foods (blueberries), reducing their weight loss by 20 % and 8 % after 28 days at room and refrigerated temperatures, preserving the diameter of the blueberries and inhibiting fungal growth, corroborating an improvement in functional properties. Moreover, IC-U and IC-K incorporation did not affect Young's modulus (85 N/mm²), tensile strength (19 N/mm²), elongation at break (553 %), and disintegration degree (90 %) of the films, making them alternative food preservation packaging for the food industry.
