<p><strong>Aim:</strong> The fundamental rationale for a systematic literature review is to examine opportunities and challenges in the privatization of solid waste management, and share knowledge to spark and inspire a process that will usher in public private partnership to ensure cities are kept clean for habitability. <strong>Methodology and Results:</strong> A systematic review of the literature using information obtained from different sources was performed. The Google Search Engine was used to search for these articles. During the search numerous combinations of words and phrases were used to ensure articles reflect the most recent knowledge and scholarly works. Only peer-reviewed articles published after 2000 were selected, except extracts perceived to be of fundamental mileage to the study. However, articles published by staunch international organizations working in privatization of solid waste management for years which had produced indefatigable knowledge in the field were stealthily appraised. The privatization of solid waste management has resulted in some successes which include, but not restricted to: effectiveness, cost saving, timely service delivery, access to funding and expansion, quality services, partnership and community participation, cleanliness and healthy environment, jobs creation and better income, elimination of public monopoly and promotion of competition, new technologies and innovative techniques, public sector concentration on supervision, resources conservation and protection from risks; less bureaucracy and prompt action regarding concerns and complaints. <strong>Conclusion, significance and impact of study:</strong> With a well-thought model and proper public supervision, the privatization of solid of waste management can deliver habitable cities, though not without negative impacts and obstacles.</p>

Negative Impacts

Various municipal solid waste management (MSWM) innovations have emerged in developing countries in face of the challenges posed by increasing waste generation and poor MSWM practice. We present a methodology to assess the potential sustainability impact of MSWM innovations in a holistic manner. The Life Cycle Sustainability Analysis (LCSA) framework and the United Nations (UN) sustainable development goals (SDGs) facilitated the methodology development. The result of applying the methodology to the case of waste bank (WB) in Bandung City shows that WB potentially generates the greatest sustainability impact in the resource recovery phase and the smallest impact in the collection and final disposal phase. All negative impacts could arise in the economic dimension. Surprisingly, WB as a national strategy to achieve 3Rs would not effectively solve Bandung City’s landfill problem. Almost all SDGs would benefit from the WB program under the assumed conditions. This methodology will facilitate the decision-making in MSWM by (1) comparing available innovations to find the optimal solution, (2) identifying the hot spots and taking measures to combat the negative impacts, (3) providing the basis for monitoring the implementation process and the ex-post performance assessment.

Negative Impacts

Universities are complex organizations, so when implementing an EMS and adopting strategies, methodologies and programs they must involve the entire university system to minimize the negative impacts on the environment and, thus, lead the search for sustainable or carbon neutral organizations. Carbon Footprint was used as an indicator to measure the sustainability effectiveness of the environmental programs implemented and promoted by the EMS-ITM and how they mitigate the emission of GHGs. The calculation of this indicator was developed following ISO 14040-14044 and ISO 14064, for the ITM-Robledo campus and for the period 2015-2017. The results show the relevance and the reduction in the GHG emission levels achieved by the environmental programs studied, especially by the comprehensive solid waste management program, with which the highest levels of mitigation are achieved.

Hierarchy Process

The promotion of tourism by the government and the creation of local tourist attractions are becoming extremely popular. This has direct negative impacts on the environment, especially the existence of a significant quantity of garbage and its ineffective management. The upstream areas that experience considerable tourism often face problems in solid waste management (SWM), especially in areas with management limitations. The purpose of this study is to study the various important factors that affect the efficiency of SWM from tourism in the upstream areas by exploring the attitudes of those involved in the Pai district, Mae Hong Son Province, using the questionnaire. The questionnaire has been analysed by statistical methods using the SPSS program, and, then, the data has been analysed by 16 experts from 8 related fields using the analytical hierarchy process (AHP) to prioritise the factors affecting the efficiency of waste management from tourism in upstream areas. The study indicated that a total of 30 factors were grouped into 5 groups. The highest important factor is personnel and knowledge, followed by budget and equipment, area and strategy, cooperation and process, and economy and society. Executive vision is the most important secondary factor towards SWM resulting from tourism in the upstream areas. The summary of this research can be used to effectively drive spatial work, which is suitable for small cities located in upstream areas, and growth in tourism, and such information can be applied to other areas that have similar characteristics, which will lead to efficient spatial SWM.

The environment is heading towards a potential risk due to unsustainable waste disposal. It is a sensitive issue which concerns about serious environmental problems in today’s world. The present situation of direct dumping of the waste without proper inspection and separation leaves a serious impact of environmental pollution causing a tremendous growth in health related problems. “Domestic, industrial and other wastes, whether they are of low or medium level wastes, they are causing environmental pollution and have become perennial problems for mankind. If this situation is not handled in a proper manner within time then it would lead to worse consequences on a global level. There has been development of new technologies for improving the waste management systems. In this paper we attempt to show a detailed analysis of three crucial parameters: distance, time and cost affecting the solid waste management system by a direct comparison of existing routes and through the routes obtained by application of Arc GIS. Method adopted for analysis is VAM (Vogel’s Approximation Method) a part of Transportation model, and results of the same are validated using MATLAB Software programmed exclusively for VAM.

The elevation of waste generation subsequent to population growth has become a severe environmental topic in Malaysia. Since most of the waste is being dumped into a landfill, the open dumpsite, or unsanitary landfills which are not constructed with proper engineering plan, severe impacts on the environment result. The energy demand in Malaysia increased with the growing population, but reliance on fossil fuels to generate electricity has created another greenhouse gas contributor. Alternatively, waste-to-energy technology solves the problem of increasing waste by converting the waste to a renewable energy source. Malaysia has moved towards landfill gas recovery system and incineration for waste energy recovery. The recovery system and refuse-derived fuel plant achieved expectation; however, the incineration plants have failed due to the opposition of the public, lack of funding and technician expertise, and other technical issues. The solid waste management practices lacking separation and recycling sources, become an obstacle for development. The government puts effort into solving the current issue by promoting recycling in the public, enforcing the legislation, and approaching new technologies for better solid waste management practice in the future. This paper aims to discuss the application of energy recovery from municipal solid waste in Malaysia.

Negative Impacts

Improper Solid Waste Management leads to the generation of landfill leachate at the landfills. To reduce the negative impacts of highly toxic and recalcitrant leachate on the environment, several techniques have been used. A lot of research is conducted to find suitable methods for the treatment of landfill leachate such as biological processes, chemical oxidation processes, coagulation, flocculation, chemical precipitation, and membrane procedures. The biological process is still being used widely for the treatment of leachate. The current system of leachate treatment consists of various unit processes which require larger area, energy and cost. In addition, the current aerobic treatment is not able to treat entirely the pollutants which require further treatment of the leachate. Anaerobic wastewater treatment has gained considerable attention among researchers and sanitary engineers primarily due to its economic advantages over conventional aerobic methods. The major advantages of anaerobic wastewater treatment in comparison to aerobic methods are: (a) the lack of aeration, which decreases costs and energy requirements; and (b) simple maintenance and control, which eliminates the need for skilled operators and manufacturers. Several anaerobic processes have been used for leachate treatment such as up-flow anaerobic sludge blanket (UASB) reactor, anaerobic filter, hybrid bed reactor, anaerobic sequencing batch reactor and Anaerobic baffled reactor. The following chapter provides an insight to the solid waste management at the landfills, generation of leachate and details of some of the highly efficient anaerobic treatment systems that are used for the overall treatment of landfill leachate.

The Impact

The processes related to solid waste management (SWM) are being revised as new technologies emerge and are applied in the area to achieve greater environmental, social and economic sustainability for society. To achieve our goal, two robust review protocols (Population, Intervention, Comparison, Outcome, and Context (PICOC) and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA)) were used to systematically analyze 62 documents extracted from the Web of Science database to identify the main techniques and tools for Knowledge Discovery in Databases (KDD) and Data Mining (DM) as applied to SWM and explore the technological potential to optimize the stages of collecting and transporting waste. Moreover, it was possible to analyze the main challenges and opportunities of KDD and DM for SWM. The results show that the most used tools for SWM are MATLAB (29.7%) and GIS (13.5%), whereas the most used techniques are Artificial Neural Networks (35.8%), Linear Regression (16.0%) and Support Vector Machine (12.3%). In addition, 15.3% of the studies were conducted with data from China, 11.1% from India and 9.7% of the studies analyzed and compared data from several other countries. Furthermore, the research showed that the main challenges in the field of study are related to the collection and treatment of data, whereas the opportunities appear to be linked mainly to the impact on the pillars of sustainable development. Thus, this study portrays important issues associated with the use of KDD and DM for optimal SWM and has the potential to assist and direct researchers and field professionals in future studies.

This study was conducted to assess the awareness level of 786 families regarding solid waste management in Pol-e-Khumri. A total of 331 questionnaires were distributed among participants of different educational degrees and age groups from which only 310 questionnaires were returned back. Collected data were analyzed using statistical package for social science (SPSS) software. The results of this research showed that 58% of participants had weak general awareness regarding solid waste management, while 29% and 13% of them had moderate and good awareness level of awareness, respectively. Also, participants had satisfactory level of knowledge about responsible administrations (75%) and negative impacts of waste dumping (60%) while, they had moderate level of awareness regarding solid waste management (40%), waste collection (50%) and transportation (45%). Participants showed poor awareness level regarding solid waste disposal methods (25%), source segregation of waste (30%) and hazardous waste (35%). The relationship between the demographic characteristics of respondents (sex and level of education) and their general awareness level was also evaluated. It was found that participants with low education degree have less awareness as compared to participants with high degree of education. Study suggests that there must be an integrated program about solid waste management and enhancing public awareness. Short- and long-term educational programs such as discussions, seminars, workshops and preaching in Masjids are considered to be useful in enhancing public awareness level.
