Sustainable Waste Management in Malaysia: Leveraging Supply Chain Solutions for a Greener Future

Sustainable waste management has become a critical global concern, and Malaysia is no exception. With the country's increasing urbanization and economic growth, waste generation has risen significantly, posing environmental and social challenges. This paper explores the concept of sustainable waste management in Malaysia and proposes leveraging supply chain solutions as a pathway towards a greener future. The study examines the current waste management practices, their limitations, and the potential environmental impacts. It highlights the need for integrated and innovative approaches encompassing the entire waste management supply chain, from collection to disposal. By adopting sustainable supply chain practices, such as waste segregation, recycling, and waste-to-energy conversion, Malaysia can achieve more efficient resource utilization, reduce greenhouse gas emissions, and minimize landfill usage. Furthermore, the paper addresses the role of government policies, private sector engagement, and public awareness in fostering a successful transition towards sustainable waste management. The findings and recommendations presented in this study contribute to the ongoing efforts to develop a comprehensive and eco-friendly waste management system in Malaysia and serve as a model for other developing nations facing similar challenges

DESIGN OF A WASTE MANAGEMENT MODEL USING INTEGRATED ORGANIC AND SOLID WASTE MANAGEMENT: A CASE OF GAMBIRONO SUBDISTRICT, JEMBER

The aim of this article is to design a waste management model for Gambirono subdistrict, Jember based on integrated organic and solid waste management system. The increasing organic and solid waster generation in the sub-district of Gambirono is evidenced by increased number of illegal dumping of waste in the rural communities. In this article, a model that identifies recycling processing that generates additional income to manage organic and solid waste and also incorporating the key performance indicators or metrics for organic and solid waste management services has been designed. The design shows a clear depiction of the environmental management acts and the municipality by-laws. Performance measurement which is very critical in waste management has been incorporated. Model design focus was on separation of types of waste, collection, waste treatment, disposal methods of useless waste and waste bank management have therefore been depicted in the model. The model provides easy access to data for the formation and implementation of effective organic and solid waste management policies, strategies and programs to achieve sustainable waste management

Assessment of maturity of reverse logistics as a strategy to sustainable solid waste management

Small- and medium-sized enterprises primarily focus on their operations and rarely pay attention to issues related to sustainable solid waste management that originate from their production processes. A suitable strategy to support sustainable solid waste management is reverse logistics. Through the use of maturity models, it is possible to determine the grade to which small- and medium-sized enterprises are prepared to perform this strategy. This study proposes an adapted maturity model to measure maturity levels of reverse logistics aspects at small- and medium-sized enterprises in regions from Colombia in order to contribute to sustainable solid waste management. The maturity model was applied to seven small- and medium-sized enterprises in the plastics sector in the central and southern regions of Colombia by adapting a maturity model that was previously correlated to suggested drivers and barriers in this sector. Results show that maturity levels range from naïve to immature owing to the incipient development of reverse logistics in Colombia. Therefore, it is necessary to establish a holistic vision of the organisation to improve the reverse logistics decision-making process to achieve sustainable solid waste managemen

CENTRALIZED AND DECENTRALIZED APPROACHES TO SOLID WASTE MANAGEMENT – A CASE STUDY

Rapid urbanization and alteration in lifestyle occurring across the globe has resulted in an un-controlled generation of municipal solid waste. Various strategies have been tried and tested for obtaining a sustainable result in municipal solid waste management. Nonetheless, in most of the cases, they have created negative health, environment and socio-economic impacts, particularly in developing countries. Furthermore, the attitude of the common people towards the waste they generate, often acts as a barrier for adopting sustainable strategies for its management. Two main approaches are being followed in municipal solid waste management: a centralized and a decentralized approach. There exists an ongoing debate with regard to the efficiency of the two approaches. Taking the Thiruvananthapuram Municipal Corporation in Kerala, India as a case to observe, this paper examines the merits, demerits, and practicability of these two approaches, and tries to suggest a sustainable model to curb the issue of municipal solid waste management in urban settings

Sustainable Waste Management for Campus Construction Projects - Case of UMass, Amherst, USA

The optimum use of resources and the efficient management of waste are the most vital principles of sustainable building, which significantly reduces the negative impacts of construction on the environment and preserves its natural resources. Several institutions supported by local governments in the United States have acquired the experience and the methodology to develop policies, guides, and demonstration projects to enhance construction waste management of building projects in a sustainable way. Massachusetts has specifically presented several green building initiatives with particular regard to construction waste management. The University of Massachusetts (UMass- Amherst) is a prominent state institution with a campus classified as “Green”. Thus, this study addresses the management of construction waste at UMass as a model by exploring the governing framework, and highlighting the measures that define the process of construction waste management for campus projects. Throughout the study, waste management considerations, guidelines, and policies are reviewed, field visits are conducted, and conclusions are derived in order to improve the management performance of campus construction waste, thereby advising other institutions on better management practices

Identification and analysis of attributes for industrial food waste management modelling

Due to the large quantities of food waste generated by manufacturers and the associated environmental impact of these waste streams, improving food waste management is vital for achieving a more sustainable food system. Management of food waste can be complex and the most appropriate methods may not always be selected. There are a range of aspects to consider in order to select the most sustainable option to manage food waste, such as the specific type of food waste generated, waste management options available, characteristics of food companies that generate food waste, features of the waste management processors that will manage it, and the sustainability implications of dealing with the food waste. To support food waste management decision making, this paper presents a modelling procedure to assist in identifying what type and range of information is needed to model food waste management systems, allowing the user to follow a systematic methodology to make more informed decisions. This procedure is based on the identification and analysis of qualitative and quantitative attributes necessary to model food waste management and an assessment of their relationships. Specifically, it describes a process to ensure that all relevant attributes are considered during the decision-making process. A case study with a large UK food and drink manufacturer is used to demonstrate the applicability and usefulness of this procedure. In conclusion, the systematic procedure presented in this paper provides a methodology to identify opportunities to improve the sustainability of industrial food waste management. The data obtained can be used to further undertake a life-cycle assessment study and/or to apply existing socio-economic methodologies to thoroughly assess impacts and benefits of food waste management

Recycling of municipal waste in Slovak cities

Among the most urgent topics within waste management policy is the gradual transition of the economy from a linear model towards a circular economy with a more sustainable way of using resources. The European Union has responded to these changes by passing new legislation and ambitious targets so that all member states can quickly work towards achieving a greener and more sustainable Europe. However, the starting position for achieving the desired goals differs significantly from one country to another. In this paper, we therefore looked at the position of Slovakia in relation to selected waste management indicators, and at the measures taken so far. Moreover, since waste management falls under one of the many public benefit services provided under the remit of local governments, we also monitored the specific contribution of Slovak cities to the newly established trend of waste management in the country.Among the most urgent topics within waste management policy isthe gradual transition of the economy from a linear model towards a circulareconomy with a more sustainable way of using resources.

MODEL OPTIMASI PENGELOLAAN SAMPAH DI TPA

The increase in waste generation is a major problem especially for urban areas such as Jakarta with insufficient landfill capacity and an inefficient and environmentally sound waste management system. To produce an optimal, integrated and sustainable landfill management strategy, an analysis of the TPST Bantargebang waste management system is then formulated towards optimization of sustainable landfill management in environmental, financial, and social aspects through a system dynamics intervention scenario model of the TPST Bantargebang waste management system. Based on the descriptive analysis carried out on the latest waste management, 3 main issues are known, namely, landfill capacity almost fully occupied, methane gas emissions increment, and the possibility waste pickers integration to increase scavenging productivity. Simulations were carried out with a system dynamics model for the 2018-2023 period with BAU conditions and an intervention scenario with a reduction in landfill waste and a reduction in waste flow. The results of the scenario are: landfill can still be utilized until 2023; methane gas emissions decreased by an average of 23,50%; the increase in the Scavenger Production Ratio to the Landfill Waste Rate reached 134,58%. As a consequence of the intervention and the addition of waste treatment activities in the TPST Bantargebang, the operational cost per ton has increased up to 309,62%. This study concludes that the scenario of incoming waste reduction and existing landfill waste reduction planned by Material Recovery Facility (MRF) construction with scavenger involvement, compost processing efficiency improvement, construction of Waste to Energy (WtE) facilities in the form of incinerator, landfill mining, and reprofiling simultaneously

Toward Green, Clean and Sustainable Environment

The purpose of this paper is to create an appropriate waste management model for UNISSULA that proclaim a clean, green and sustainable environment based on waste processing for economic value and ecological enviroment. A brief overview of the concept includes development of management system of regional waste, education & waste management & WMS training, waste handling, waste processing and utilization of waste processing products. However, UNISSULA's concept has some weaknesses that must be overcome in order this concept could be running well such as: capacity of garbage, area, infrastucture (grabage fleet) and smart cards and automatic container system. It is therefore, needed cooperation with Semarang City Government' that is by collaboration concept of UNISSULA with Semarang City Government’s concept to ensure the input capacity, and people support. As a result, the creation of a vicious circle of urban rubbish management namely, economic stimulation, clean environment, government income and people income and economic structure. Besides that, this concept is expected to improve economic citizen through economic value added of waste. The next is expected to change the culture, urban lifestyle, green behavior, clean environment, transportation and income, and farming, fruits and vegetables industry.
