Makkah City

In many countries, open dumping is considered the simplest, cheapest, and most cost-effective way of managing solid wastes. Thus, in underdeveloped economies, Municipal Solid Wastes (MSW) are openly dumped. Improper waste disposal causes air, water, and soil pollution, impairing soil permeability and blockage of the drainage system. Solid Waste Management (SWM) can be enhanced by operating a well-engineered site with the capacity to reduce, reuse, and recover MSW. Makkah city is one of the holiest cities in the world. It harbors a dozen of holy places. Millions of people across the globe visit the place every year to perform Hajj, Umrah, and tourism. In the present study, MSW characterization and energy recovery from MSW of Makkah was determined. The average composition of solid waste in Makkah city is organic matter (48%), plastics (25%), paper and cardboard (20%), metals (4%), glass (2%), textiles (1%), and wood (1%). In order to evaluate energy recovery potential from solid waste in Kakia open dumpsite landfill, the Gas Generation Model (LandGEM) was used. According to LandGEM results, landfill gas (methane and carbon dioxide) generation potential and capacity were determined. Kakia open dump has a methane potential of 83.52 m3 per ton of waste.

Waste Management Practices

One of the most important environmental problems is municipal solid waste management (MSWM) as a result of the rapid rise in waste generation due to industrialization, economic development, urbanization, and rapid population growth in Turkey. The collection, transportation, and disposal of solid waste are conducted by municipal authorities of Turkey. The waste management problem is getting more serious due to some reasons such as lack of enforcement of regulations, weak technical and financial resources, poor infrastructure, insufficient policies and deficiency of political priorities, poor coordination between authorities. Hence, despite the legislation, municipal solid wastes are managed in an unscientific manner by the municipalities. The SWOT analysis is a perfect tool to discover the possibilities and ways for successfully implementing the MSWM. In this study, SWOT analysis carried out both negative and positive concerns of MSWM. A successful strategic management has been identified from the SWOT analysis for the municipal solid wastes. Further, the study proposes options based on SWOT analysis approach to improve in available waste management practices that could also be adopted by other countries to decrease the adverse effect of MSW on human and environment health.

Solid Waste Generation

Solid wastes management is a major problem that has reached alarming proportions requiring drastic measures. The increasing difficulty in managing wastes in Nigeria has become one of the most intractable environmental issues. There is unprecedented increase in the rate of wastes generated by the residents. The cardinal aim of the study is to “ascertain the assessment of solid waste management generated in Eziobodo community, Owerri west, Imo state, Nigeria”. To achieve this aim, 140 copies of questionnaires were administered to the residents of Eziobodo community selected at random sampling. Of these, 112 copies of the questionnaire (80.0%) were returned and analyzed using descriptive statistics. Data from the questionnaires were analyzed by simple frequency and presented by percentage. The study revealed among others that: residential buildings accounts for the highest generation source of solid wastes in the community and the solid wastes were predominantly nylon/nylon bags/ nylon sachets; food waste, plastic can/rubbers  arranged in their order of severity. Consequently, the effect of the solid waste in the community were; wide and easy spread of disease vectors, soil pollution and easy breed of flies, rats and mosquitoes. Hence the study recommends, sorting of solid waste before dumping, provision of adequate skips and dustbins and ensuring regular collection of wastes. Finally, potential for a sustainable approach to management of solid wastes such as recycling, reuse, energy recovery and waste reduction.

Nationally, expenditures for solid waste collection and disposal are exceeded only by spending on schools and roads [3, p. 1]. In Texas, recent legislation which establishes minimum acceptable standards for disposal of municipal solid wastes materially affects the future costs of operating solid Waste management systems for smaller rural communities.The 1969 amendment to the Texas Solid Waste Disposal Act establishes the minimum legal standards for disposal operations in rural communities. The State Department of Health was given the responsibility for enforcement of regulations involving the collection, handling, storage and disposal of municipal solid wastes. After January 1, 1973, data presented in support of the disposal operations in Texas communities larger than fifteen hundred people must be prepared by a registered professional engineer and submitted to the State Department of Health for approval. Under the auspices of this act all towns with a population of between three thousand and five thousand are required to operate a sanitary landfill with compaction and cover at least twice per week.

The management of municipal solid waste (MSW) appears to be one of the major ecological problems at present. Selecting sites for the disposal of municipal solid wastes or waste utilization facilities is one of the most contentious aspects of waste management. The present study aimed to develop the methodology to assess the natural protection of the geological environment from contamination upon the implementation of large ecological projects due to the allocation of MSW utilization facilities. The case of the Central Federal District of Russia (CFD) is taken as an example. The suitability of territories for municipal solid waste disposal is assessed according to the presence of weakly permeable deposits in the geological cross-section and their occurrence mode. A “map of engineering geological zoning CFD by the conditions of allocation MSW disposal sites and utilization facilities” has been compiled to a scale 1:2500000. The map gives a general indication of the suitability of the planned sites for waste disposal within the regarded region and showed that, for the bulk of territory, the allocation of MSW disposal and management facilities requires undertaking additional measures for the geoenvironmental protection from contamination.
