  • The portion of the recycled paper and paper board packaging material has been the highest in recycled municipal solid waste since 1960 but still the portion of the discarded paper and paper board packaging material is the highest (32.3%) in whole discarded municipal solid waste in USA. In order to reduce more the discarded paper and paper board, the common municipal solid waste treatments were compared and recycling treatment was still recommended for the the discarded paper and paper board rather than of the waste treatments, landfill, incineration, and source reduction. In this paper, the obstacled of recycling treatment of the paper and paper board in municipal solid waste and new application of recycled paper and paper board packaging material are discussed.

  • The indiscriminate growth in global population poses a threat to the world in handling and disposal of Municipal solid waste. Rapid urban growth increases the production, consumption and generation of Municipal solid waste which leads to a drastic change in the environment. The methane produced from the Municipal Solid waste accounts for up to 11% global anthropogenic emissions, which is a major cause for global warming. This study reports the methane emission estimation using IPCC default, TNO, LandGEM, EPER and close flux chamber from open dump yards at Perungudi and Kodungaiyur in Chennai, India. The result reveals that the methane emission using close flux chamber was in the range of 8.8 Gg/yr-11.3 Gg/yr and 6.1Gg/yr to 9.1 Gg/yr at Kodungaiyur and Perungudi dump yard respectively. The per capita waste generation was estimated based on waste generation and population. The waste generation potential was projected using linear regression model for the period 2017-2050. The trend of CH4 emission in the actual field measurement were increased every year, similarly the emission trend also increased in IPCC default method (mass balance approach), EPER Germany (zero order decay model) where as TNO and Land GEM (first order decay model) were decreased. The present study reveals that Kodungaiyur dump yard is more vulnerable to methane emission compared to Perungudi dump yard and has more potential in waste to energy conversion mechanisms than compare to Perungudi dump yard.

  • A hear transfer model was developed to calculate the temperature distribution in the rotary kiln incinerator of municipal solid waste. The thermo-gravimetric characteristics of waste and the gas-to-waste heat transfer coefficient were determined by comparing the experimental results and model prediction. With this, heat transfer rates by existing heat transfer mechanisms were calculated to be compared each other. The effects of treatment capacity, calorific value of waste, and flow rate and temperature of combustion air on the temperature distribution in the rotary kiln incinerator were predicted by the model developed in this work.

  • Many cities and provinces are rapidly depleting landfill spaces. As the result, some municities have adopted to incinerate their municipal solid waste(MSW). The motive behind the choice is that incineration significantly reduces the volume of solid waste in need of disposal, destroys the harmful organic compounds that are present in MSW, and provides an attractive source of alternative energy. Conclusively, the generation of MSW ash is expected to increse in the furture. However, disposing the MSW ash in landfills may not always be an environmentally or an economically feasible solution. This paper addresses the various issues associated with MSW ash and its possible use in construction applications.

  • In order to investigate the quantitative and qualitative properties of leachate with different composition of MSW in solid waste landfill, three lysimeters filled with bottom ash only (Lysimeter A), bottom ash 70%+municipal solid waste 30% (Lysimeter B), and municipal solid waste only (Lysimeter C) respectively were operated under actual meteorological conditions. From the results, Lysimeter A and Lysimeter B were much higher than Lysimeter C in terms of cumulative generation rates of leachate. The pH in leachate from Lysimeter A are in the range of pH 9 to 11, however, the pH of the leachate was gradually changed to the neutral with time. In the case of $Cl^-$, leachates from Lysimeter A and B with bottom ash have high $Cl^-$ concentration whereas leachate produced from Lysimeter C has low $Cl^-$ concentration. In the Lysimeter C with municipal solid waste only, concentration of organic materials in the leachate was much higher than that of leachate produced from the other Lysimeters.

  • Biomass has been used for energy sources from the prehistoric age. Biomass are converted into solid, liquid or gaseous fuels and are used for heating, electricity generation or for transportation recently. Solid biofuels such as bio-chips or bio-pellet are used for heating or electricity generation. Liquid biofuels such as biodiesel and bioethanol from sugars or lignocellulosics are well known renewable transportation fuels. biogas produced from organic waste are also used for heating, generation and vehicles. Biomass resources for the production of above mentioned biofuels are classified under following 4 categories, such as forest biomass, agricultural residue biomass, livestock manure and municipal organic wastes. The energy potential of those biomass resources existing in Korea are estimated. The energy potential for dry biomass (forest, agricultural, municipal waste) were estimated from their heating value contained, whereas energy potential of wet biomass (livestock manure, food waste, waste sludge) is calculated from the biological methane potential of them on annual basis. Biomass resources potential of those 4 categories in Korea are estimated to be as follows. Forest biomass 355.602 million TOE, agricultural biomass 4.019 million TOE, livestock manure biomass 1.455 million TOE, and municipal organic waste 1.074 million TOE are available for biofuels production annually.

  • The management of municipal solid waste (MSW) is essential for every community; and, it is currently a major challenge in Nigeria. This paper provides an overview of the current MSW management trends in Nigeria and proposes new sustainable MSW management systems. Across Nigerian cities, MSW management is characterized by inefficient collection and transportation to disposal sites. Collection services do not reach some unplanned areas and slums due to poor street network. Even some planned areas are not reached by collection services. The informal sector contributes to waste collection, resource recovery and recycling; however, their activities are not recognized by the governments. Markets exist for recovered materials but more efforts need to be geared towards intensive recovery of materials and expansion of these markets. Despite the high proportion of putrescible matter in MSW, the only form of treatment commonly used currently is open burning for volume reduction. The high organic fraction presents a great opportunity for composting and anaerobic digestion. Ultimate disposal is currently done in open dumpsites. This needs to be upgraded to engineered landfills that are properly sited and adequately operated by well trained personnel. There is an emerging waste stream of concern, electronic-waste (e-waste), that requires urgent sustainable management as e-waste are currently co-disposed with other waste streams or burnt in the open posing detrimental health impacts.

  • The removal rate of Cl from municipal solid waste incineration(MSWI) ash(bottom ash and fly ash) by washing was investigated. The Cl contents in the bottom ash and fly ash were 2.6-3.0% and 25-30% respectively, and KCl, NaCl, CaCIOH and friedel's salt were main components. From the results on the effects of washing time and temperature, the Cl contents in the bottom ash and fly ash were decreased up to 0.3% and 2.0% respectively by using of water as a solvent within 30 min at 2$0^{\circ}C$, 300 rpm of agitation speed and 10 of liquid/solid ratio. It is expected that the removal of Cl from the incineration ash by washing could make use of the ash for a cement raw material and so on.
