Harmful Effects

Refuse dumpsites are found scattered within and outside cities in Nigeria and the open burning of these dumps is a common practice mainly as a waste and odour reduction measure. Open incineration of wastes emits dangerous gases into the atmosphere. The environmental and public health hazards related to open burning of wastes dumps have often been overlooked in most parts of Nigeria and there is limited documentation on this for the study area. This study is aimed at investigating the environmental effect of the burning of open refuse dumps at five locations within Jos Metropolis, Nigeria. Air quality in and around the study area were measured. The results showed that the oxygen levels for all the locations for the different conditions tested ranged between 14.2% and 17.5%. This showed that whether the dumpsites were burning or not the oxygen levels within the vicinity were below the comfortable level of 19.5%. CO levels ranged between 2ppm – 9ppm with the maximum value of 9ppm measured at Apata when the refuse containing some plastics was burning. The values of CO may not be significant but the duration of exposure may make a difference on public healthas most of the dumpsites are located within residential and commercial areas. CO2 values, which ranged between 361ppm to 700ppm, are all higher than standard acceptable levels of 350ppm. The implication is that burning refuse in the open increases the quantity of CO and CO2 in the atmosphere which will likely be of adverse health implication to the residents living close to such areas. It can be concluded that existence and burning of open refuse dumps contributed to the increase in values of air quality parameters measured around the dumpsites. To avert the harmful effects of indiscriminate dumping and burning of solid wastes within residential, commercial and other areas, it is recommended that there should be improvement in solid wastes management in Jos city and environs among other necessary measures.

Public Survey

Open burning of solid wastes, a potential nonpoint emission source, has recently become a topic of interests, particularly in the metropolitan area of Seoul, Korea. To estimate the effects of irregular open burning on local air quality, we evaluated the emission levels of harmful substances from test combustion of individual types of domestic municipal solid waste (MSW), including paper, wood, and plastics. The emission factors of PM10, PM2.5, PAHs, and heavy metals obtained from laboratory tests differed depending on the combustion material. A brief survey of residents and local government officials showed that more than 10.6% of homes in the metropolitan area have eliminated waste by irregular burning. Based on the public survey in the test area, the average annual emissions of hazardous materials from frequent open burning was estimated to be 71 tons for PM10, 46.6 tons for PM2.5, 914 kg for heavy metals, and 67 kg for PAHs. Open burning creates nearly 0.44% of regional air pollution from PM10.

For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.

Optimum Dosage

Conditioning of sludges improves dewatering characteristics and reduces the quantity of sludge to be handled. Anaerobic digested sludge collected from a sewage treatment plant contained 1.8% to 8% oil. The increase of specific resistance and capillary suction time (CST) with increasing oil content observed in these samples indicates the interference of oil in dewatering. It has been found that addition of municipal solid wastes incinerator fly ash decreases the specific resistances and capillary suction times of oily sludges rapidly up to 3% dosage. Beyond 3% fly ash, the decrease is less significant and the solids content in the sludge cake increases. This optimum dosage remains the same for sludges with varying oil contents from 1.8% to 12%. The total suspended solids of filtrate decreases with fly ash dosage but the toxic concentrations of heavy metals increases considerably. However at the optimum dosage of 3%, concentrations of heavy metals are within the limits for discharging into the sewers. The correlations of CST with the dewatering characteristics such as specific resistance, filter yield and corrected filter yield are established. These correlations can be used to obtain a quick prediction on dewaterability.

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.
