Waste Disposal Management Research Articles

Evaluating and prioritizing strategies to reduce carbon emissions in the circular economy for environmental sustainability.

The conversion of economic system into a circular economy (CE) is indispensable, as it is the key strategy in combating climate change and reducing carbon dioxide (CO2) emissions in China. However, difficulties are inevitable during this process. It is essential for the long-term operation of a CE to adequately address and overcome any challenges it faces. The present research used the Fuzzy Analytical Hierarchy Process (FAHP) approach to determine the main challenges and sub-challenges in the context of CE and its ability to help reduce the CO2 emission levels for carbon-free economy. Next, the study used the Fuzzy VIekriterijumsko KOmpromisno Rangiranje (FVIKOR) method to measure the strategizing solutions, which are hindering the effective use of CE towards the green future. The findings of the FAHP indicated that waste management disposal (CECER2) is the most crucial challenge. The regulatory and policy complexity (CECER5) and financial investment and cost considerations (CECER4) are the next key challenges. The results of the FVIKOR revealed that policy and regulatory support (CES6), waste reduction and zero waste goals (CES4), and recycling and upcycling (CES2) are most significant mitigation strategies for lowering carbon emissions through CE for environmental sustainability in China. The implications reveal the essential need for tailored policy frameworks and financial incentives to promote implementation of CE strategies, leading to substantial carbon emissions reduction in China.

Zero Plastic Drive: A Comprehensive Review on Unveiling Innovative Sustainable Solutions for a Circular Plastics Economy

Living in a society where plastic has become a necessity, the over-reliance on these materials is quite disturbing as they have social and economic effects, especially in waste disposal and resource management. Such issues have introduced the circular plastics economy (CPE), which aims to eliminate plastic waste by focusing on reducing, recycling, and reusing (3R) and designing biodegradable plastic products. Owing to these facts, a systematic literature review (SLR) was conducted to analyze the existing literature on circular economy principles and plastic waste management systems in terms of 3R initiatives. Also, this study showcases the CPE by investigating how it is possible to manage plastic within a circular economy instead of a linear system. Additionally, system dynamics modeling (SDM) was applied to examine the inter-relationships between key elements such as plastic production, waste generation, recycling rates, and regulatory actions, along with the cognizance phase of waste diversion and advanced sorting technology to minimize landfill dependency and environmental pollution initiatives, including producer responsibility programs and zero-landfill targets. This study accumulated that zero waste strategies, such as plastic circularity, national waste management, and high-quality recycling, have achieved recycling rates ranging from 30% to 81% across various countries, significantly reducing plastic waste and enhancing resource efficiency. However, the added strategies in countries that are related to policy-driven initiatives can prospectively be useful for increasing recycling capacity to eliminate plastic waste in landfills, promoting a circular economy and sustainable waste management practices. This study also involved the critical stakeholders of the CPE who will make the utilization of plastic waste a reality. Ultimately, this research contributes to the fast-growing knowledge base on plastic waste management by presenting an interdisciplinary framework based on model synthesis and mathematical modeling, which is crucial for decision-makers, industries, and researchers.

The Estimation of Greenhouse Gas Emissions from the Waste Sector in Lao PDR

Greenhouse gases (GHGs), such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases, are key contributors to global climate change by trapping heat in the Earth's atmosphere. The waste sector, encompassing solid waste disposal, biological treatment, incineration, and wastewater management, is a significant source of GHG emissions. This study aims to assess and quantify GHG emissions from the waste sector in Lao PDR, analyze the contribution of wastewater treatment and discharge to methane emissions, and identify gaps in the current data on waste management emissions. Using the Tier 1 methodology outlined in the 2006 IPCC (Intergovernmental Panel on Climate Change) guidelines, this research evaluates emissions from the waste sector in Lao PDR from 1960 to 2022. The results reveal a total of 1,631.89 GgCO2eq emissions, with methane (CH4) contributing 1,536.25 GgCO2eq, nitrous oxide (N2O) 95.47 GgCO2eq, and carbon dioxide (CO2) 0.17 GgCO2eq. Wastewater treatment and discharge emerge as the primary source of methane emissions, responsible for 980.68 GgCO2eq. Despite these findings, the study identifies significant gaps in data collection, particularly in areas like biological treatment and open burning of waste, which were not comprehensively included. These limitations highlight the need for further research to gather more extensive and accurate data across Lao PDR, especially to better understand the full emissions profile of the waste sector.

Green Management Framework Early Implementation With a Pentuple Bottom Line Approach for IKM in Malang City

In the era of free trade encourage the Indonesian government's trade policy which leads to an increase in the high competitiveness of these products/services, Small and Medium Industries (Industri Kecil Menengah = IKM). The need for industry in IKM to have a sustainable manufacturing process is a must that must be met, considering the five pillars referred to as pentuples, namely profit, planet, people, phenotechnology, and prophet. Especially in the city of Malang, East Java Indonesia, has difficulties in terms of waste disposal and raw material management in general. Framework is needed that is able to connect the application of green management for the efficiency of the manufacturing process in IKMs by adapting existing local cultures. When they were offered an introduction to Green Management, the response they got was a fairly good, however, some obstacles occur when they try to implement good Green Management as their company strategy. The use of Green management in the management of IKM is basically acceptable to IKM entrepreneurs in the city of Malang. In its use, it can be supported by a pentuple implementation strategy that involves five components in it. So that in the end it can go towards sustainable manufacturing for IKM, especially in the city of Malang. However, when explained about the generic pentuple component, entrepreneurs can be triggered by their motivation to implement Green management through the Prophet component which contains spiritual elements. This is because the scope of entrepreneurs tends to be religious and the majority are Moslem, so it is easier to influence through this aspect.

Increasing knowledge, changing attitudes, and improving practice in SWM using the existing structure are recommended.

Assessment of Teachers’ Knowledge and Practices on Laboratory Waste Disposal

In alignment with the United Nations Sustainable Development Goals 2030 (UN SDGs 2030), which emphasise the importance of ensuring education inclusivity and quality for all, this study investigated the quality of education in the context of science teachers’ knowledge and practice related to laboratory waste disposal. Understanding the critical role that science teachers have in fostering a safe and sustainable learning environment, the research focused on the gap between the awareness and application of proper laboratory waste management techniques. Filling this gap is imperative not only for the well-being of the school community but also for the contribution to the broader goals of sustainable development outlined in the UN SDGs 2030. Consequently, this study assessed teachers’ knowledge and practice in handling laboratory waste disposal. As a qualitative research, this study used a phenomenological design with semi-structured interviews using open-ended questions to gather data from 20 public science teachers from Santa Rosa City and Cabuyao City in Laguna Province as respondents. Regarding teachers’ knowledge, three themes emerged, namely: (1) recycling techniques, (2) waste segregation and disposal, as well as (3) treatment of laboratory waste. However, the majority of science teachers admit that they have limited knowledge of how laboratory waste should be disposed of. They tended to apply basic knowledge of waste management that they already knew, despite being aware that laboratory waste should be treated differently from solid waste generated by our offices at schools. Teacher’s practice on laboratory waste disposal involved three steps, including identification, segregation of laboratory waste, and laboratory waste management disposal. Unfortunately, all were found to be inadequate to maintain proper laboratory waste disposal at schools. Hence, this study highlights the need to enhance awareness and facilitate training on laboratory waste disposal among teachers in public schools. Specific training and education on laboratory waste management, treatment, and disposal are essential for teachers in public schools who work in laboratory settings. Regular monitoring and evaluations of teachers’ laboratory waste disposal practices should also be implemented to ensure that they adhere to the proper procedures

Sustainable alternative activators from the textile mercerizing water for the durable and cost-effective flyash-GGBS based geopolymer concrete

By considering the current global challenges such as greenhouse gas emission and waste disposal management, the exploration of geopolymer concrete is highly focused now-a-days. On the other hand, the use of costlier commercial activators acted as the major drawback for the practical existence. Although the recent geopolymer researchers suggested the use of alternative activators from various resources such as palm oil ash, olive ash etc, the application of which are not appreciably promoted due to the complex derivation process. To overcome these effects, in this paper, first time, an attempt is initiated to develop a cost-effective geopolymer concrete by using textile mercerizing water as an alternate activator system. The viability of using mercerizing water instead of commercial sodium hydroxide activator was studied initially. By conducting the pH electrode test and Infrared Analysis, the alkalinity and the presence of sodium metal cations responsible for the reaction kinematics were confirmed. Also, the molar concentration of sodium cations in the mercerizing water was quantified using chemical titration analysis. The feasibility of using mercerizing water in the preparation of geopolymer was assessed using workability, mechanical strength and sustainability. From the results, it was inferred that the developed geopolymer concrete with 100 % textile mercerizing water exhibited the maximum strength of 46.9 MPa, 5.16 MPa and 5.81 MPa respectively under compression, tension and flexure which are almost equivalent and slightly better than the control geopolymer concrete. Also, the developed geopolymer concrete using 100 % textile mercerizing water and the combined flyash-GGBS binder system showcases the highest post-fire residual strength and 48 % reduced water absorption. The cost of construction of geopolymer concrete was significantly reduced by 58.43 % and showed 10.28 % reduced carbon footprint due to the complete replacement of sodium hydroxide solution using textile mercerizing water. The findings of this research work will lead to the development of equivalent molar sustainable activator from the textile mercerizing water and the exploration of eco-friendly and durable geopolymer concrete in an affordable price.

Uncovering the recycling potential of industrial waste in Sri Lanka.

The generation of industrial waste is mainly dependent on several factors, including the type of industry, production capacity, technology use and raw materials involved in the manufacturing processes. The present study is a cross-sectional study that was conducted with 580 industries under six industrial sectors in Sri Lanka in 2022. The main objective of this research was to investigate solid waste generation and estimate the recyclable fraction in the waste. Furthermore, this study calculated the prevailing recycling rate of each industrial sector and the waste generation per person employed in the sector. Industrial processes, the types and quantities of waste, waste disposal methods and management activities in terms of recycling and disposal were evaluated through a structured questionnaire and random field observations. The study identified that the composition of selected recyclable items was 16.7% of the total waste generated in the industrial sector. The prevailing rate of recycling in different sectors was as follows: manufacturing of food products (36.6%), manufacturing of beverages (82.3%), manufacturing of textiles (68.6%), manufacturing of chemical and chemical products (28.5%), manufacturing of rubber and plastic (46.5%) and manufacturing of metallic mineral products (17.8%) from the total generated recyclable material.

Activity and recyclability enhancement of pH-dependent Fe0@BC-mediated heterogeneous sodium percarbonate (SPC)-reducing agents (RA) system

Dyes pose great threats to the aquatic environment and human health. Fe0-based Fenton-like systems have been widely employed for the degradation of organic dyes. However, the regulation of degradability and recyclability was still unclear. In this study, Rhodamine B (RhB) was served as the model pollutant, hydroxylamine hydrochloride was selected as the RA, the natural photocatalysis system demonstrated stable operation. RA, as performance enhancement agent, was firstly reported in micro/nano-Zero-Valent Iron@Biochar (m/nZVI@BC) based SPC-RA system. Carrier size-fractionated m/nZVI@BC was fabricated by one-step carbothermal method. As a result, RA synergistically interacted with SPC, and the reaction time reduced from 15 min to 4 min. In the 0.010 g m/nZVI@BC-mediated SPC-RA system, over 95% of RhB (100 mg·L−1, 1041.667 mg·g−1) was successfully degraded. The maximum degradation ability could still exceed 1g·g−1 via 5 times repeated applications. Meanwhile, the loss of degradability, caused by halving SPC concentration could be compensated by RA dosage measurement. The entire degradation process was predominantly dominated by free radicals (•OH> 1O2> •O2−> •CO3−). Reactive oxidizing species (ROSs) were primarily excited by α-Fe0, Fe3C and N sites of biochar (BC). Light and BC carrier dedicated slight influence. These discoveries shed a light on the activity and recyclability regulation of catalytic material, aligning with the principles of green chemistry and cleaner production. This study demonstrates a novel approach to efficient management of solid waste disposal, reuse of waste biomass, advanced treatment of dye-containing wastewater, pollution control in aquatic environments.
