Municipal solid waste generation rate
landfill
Opis:
Accumulation of municipal solid waste in residential areas is one of the public health problems in Iraq. In the other hand, accurate and reliable information on solid waste generation rate are very important elements to plan and implement solid waste management system. The volume and surface area required for a landfill to dispose the municipal solid wastes generated in Baghdad city is evaluated in this study. The per capita solid wastes generation rates are measured for a family consists of 10 individuals by using portable balance (Salter, 0 to 130 kg). Probability sampling is used to determine the minimum number of measurements needed to evaluate the mean of per capita solid wastes generation rate with a certain level of precision (a specified error level of 5% is selected corresponds to 95% confidence that the mean value is in accurate estimate of the true value). The results indicate that an area of approximately 1603 m on a side is required for the next 20 years as a sanitary landfill for disposing the municipal solid wastes generated in Baghdad city.

Opis:
The effect of municipal solid waste on bacteria (Heterotrophic bacteria & Nitrobacteria) population was determine by collecting 50g sample’s of various dumpsites, put in 2 kg buckets soil and kept in the green house to mimic the natural environment for six (6) weeks. Analysis of variance (ANOVA) and least significant difference (L.S.D) were effected on the data at 5 % probability level. The analysis shows significant effect, this seem to suggest that municipal solid waste influences Heterotrophic bacteria and Nitrobacter population in soils.

Opis:
Industrialization becomes very significant for developing countries like India having large number of population. Rapid increase in urbanization and per capita income lead to high rate of municipal solid waste generation. In recent times, E-waste and plastic waste also contribute considerably to total waste stream due to utilization of electronic and other items. These wastes may cause a potential hazard to human health or environment if any of the aspects of solid waste management is not managed effectively. In India, approach towards Solid waste management is still unscientific. Solid Waste collection efficiency in India is around 70% (Sharholy et al. 2007), while same is almost 100% in the developed countries. Even today, large portion of solid waste is dumped indiscriminately on outskirts of towns or cities without any prior treatment. This leads to groundwater contamination and increase in air pollution due to leachate percolation and release of gases respectively. Various study reveals that out of total solid waste, 80% can be utilized again either by recycling or reusing. Improper waste segregation and other factors lead recycling sector to work on outdated technology. However, plastic and paper recycling have been especially growing due to continuous increasing consumption of both the commodities. This study describes about current status of municipal solid waste management in different regions of India. It further summarizes a collective, systematic effort which improves implementation of legal frameworks, institutional arrangements, financial provisions, technology, operations management, human resource development, and public participation and awareness of Integrated SWM systems.

Opis:
The rising levels of greenhouse gases (GHGs) in the Earth‟s atmosphere have the potential to cause changes in our climate. Some of these emission increases can be traced directly to solid waste. Landfills are among the largest emitters of carbon dioxide and methane, the key GHGs. Thus, effective mitigation of these emissions through formalization of waste reduction into the waste management system to reduce land filling could provide environmental benefits of reducing the adverse impacts of climate change. This paper therefore proposes waste prevention and recycling-jointly referred to as waste reduction as better and most potent strategies for the management of solid waste and for reducing greenhouse gases and calls on both the government and private agencies to check or control the increasing pollution or abuse of the environment by enforcing compliance with the laid out Policies, Pronouncements, Regulations and enacted Legislation especially in the developing countries. The study concludes that by choosing to prevent waste and recycle, less waste will be generated, the need for landfill will be minimal, energy demand will decrease, fewer fossil fuels will be burned and less methane and carbon dioxide will be emitted to the atmosphere which helps to curb climate change.

Opis:
A pot experiment was conducted in the green house to determine the effect of municipal solid waste on the growth of maize (zea mays). Growth parameters of percentage emergence, plant height, leaf area and number of levers per plant were collect and subjected into statistical analysis, using ANOVA and fisher’s L.S.D. at 5 % probability level. Plant growth parameters decreased with increase in cropping cycle. Similarly, maize grown on dumpsite soils did better than the control soil samples. It show increase in plant height, leaf area and number of leaves per plant at a range of 16.82 cm to 12.87 cm, 5 to 4 and 64.69 cm to 59.88 cm for the dumpsite and control samples respectively. Soil PH, organic matter (OM), total Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Sodium (Na) and Effective Cat-ion Exchange Capacity (ECEC) decreased with increase in cropping cycle respectively. The Dumpsite soil sample recorded higher mean values than the control (P < 0.05). There is every indication that municipal solid waste is beneficial to plant if only proper and careful sorting and separation of hazardous waste is done.
