Abstract (sommario):

Hazardous wastes in power grids include waste transformer oil and waste lead-acid batteries, etc. Due to the problems of extremely large number of points, wide distribution, and small number of units, coupled with differences in hazardous waste recycling technologies, policies, and markets in various regions, so Possible business models need to be listed and evaluated. This paper establishes an evaluation index system for the business model of hazardous waste recycling, and uses the TOPSIS method to evaluate five feasible business models.

Abstract (sommario):

Recycling trend has transformed the prerequisites of our cravings. Makeover of waste material into useful goods has become inevitable. Bio waste shares a major portion of waste materials, hence pursued for recycling. Activated carbon from bio waste has been reported remarkable in electrochemical performance (capacitance, charge density, charge-discharge ratio etc.). This survey of data has been compiled for different bio wastes as a source of activated carbons with conductive behavior.

In EU waste management policy the waste avoidance and reuse are under the highest priority and the recycling takes the third place while recovery and disposal are the least favourable options. The EU member states have to implement strict waste management policies based on this approach however though all countries have to prepare and implement waste management plants, their have achieved different results in waste management. The article aims to analyse the selected waste management indicators covering all stages of various wastes management ranging from prevention to recycling etc. available

The article presents an alternative method of recycling of dispersed metal waste, based on a continuous solid-liquid-phase process, implemented in rotary tilting furnaces (RTF). The new proposed method of recycling allows processing wastes with almost any composition and state from metal to oxide and multicomponent wastes (shavings, fine scrap, mill scale, aspiration dust, sludge, etc.). The wastes can be even contaminated with moisture, oil, and organic impurities. The method developed does not require preliminary preparation of the initial materials (cleaning, homogenization, pelletizing, et

Abstract (sommario):

In the era of industrialization and modernization, pollution caused by industrial wastes has become one of the biggest challenges most countries are facing. Wastes such as plastics, ceramics, paper, metals, composite, etc. are the predominant detriments to the environment. Although composite materials account for just a small proportion in the waste stream, they are difficult to process and possess a great number of potential risks to the environment. At the same time, recycling and recovering composite waste materials are more challenging than other easy-to-handle waste materials. This paper

Abstract (sommario):

There is a growing interest in electronic wastes (e-wastes) recycling for metal recovery because the fast depletion of worldwide reserves for primary resources is gradually becoming a matter of concern. E-wastes contain metals with a concentration higher than that present in the primary ores, which renders them as an apt resource for metal recovery. Owing to such aspects, research is progressing well to address several issues related to e-waste recycling for metal recovery through both chemical and biological routes. Base metals, for example, Cu, Ni, Zn, Al, etc., can be easily leached out thr

Abstract (sommario):

Abstract The construction industry generates a significant amount of waste, which presents a significant challenge for waste management. This waste includes construction and demolition waste (CDW), crushed aggregate, mortar, crushed brick, stones, etc. Reusing and recycling these wastes can reduce waste disposal and save natural resources. This research paper explores the study of the combined replacement of recycled coarse aggregate (RCA) and recycled fine aggregate (RFA) with varying proportions and evaluates the feasibility and optimum proportion of waste material as a partial replacement.

Abstract (sommario):

In South Korea, hazardous characteristics of wastes to be recycled are managed through the “Environmental Impact Assessment of Recycling” system. The ecotoxicity of medium-contact recyclable wastes, that is, those in contact with soil, groundwater, surface water, etc., is managed according to this system and is determined based on whether or not they exceed an ecotoxicity value (TU) of 2.0. The ecotoxicity of wastes is tested and determined by using pretreated eluate samples according to the Official Wastes Test Standard and applying the Official Water Pollution Process Test Standard.

Abstract (sommario):

Ho Chi Minh city (HCMC) is currently facing a critical problem of the uncontrollable municipal solid waste (MSW). The most common waste disposal practice in the city is landfilling, but this is not a sustainable solution. From 2010 to 2022, the amount of waste generated has increased annually, from 6,000 tons/day to 9,200 tons/day, with an average growth rate of 6-8% per year. This study calculated the average emission factor of various districts in the city such as districts 1, 3, etc. at 0.83 kg/capita/day and district Binh Chanh, Cu Chi, etc. at 0.73 kg/capita/day and forecasted that the am

Due to the increase of the amount of electrical and electronical equipment waste (e-waste), the understanding of individual consumers’ main decision triggers represents a key point in increasing the quantity of recycled e-waste. A series of studies from the literature have shown a positive relationship between the consumers’ attitude, awareness, self-efficacy, social norms, and their e-waste recycling intention, as well as the positive influence between the intention and the manifested behavior. Additional to these determinants, in the present study, the influence of social media was analyzed

Abstract: Garbage collection is an important task of ensuring that our communities have a pleasant environment in which to live. But the main problem we face today can be reduced by reducing or minimizing the amount of waste transportation, specific waste. A compactor can be used to reduce the amount of waste streams. The waste burden remains the same so there are no savings from the total waste generated. However, the amount of waste can be reduced by up to 80%, eliminating the need to empty the dumpster many times, resulting in lower pick-up charges. These paper focus on, to identify and ana

Mechanical recycling processes have made a great contribution to the circularity of plastic materials, contributing to 99% of recycled thermoplastics. Challenges facing this family of processes limit its outreach to 30% of plastic waste. Complementary pathways are needed to increase recycling rates. Chemical processes have the advantage of decomposing plastics into a variety of hydrocarbons that can cover a wide range of applications, such as monomer
