Municipal-solid waste (MSW) in towns and cities of Nigeria are either allowed to rot or burnt which causes the release of greenhouse gases in the process. The heap of uncollected refuse in Kano municipal causes serious health hazards and menacing public disorder. This research investigated the Kano municipal refuse for compost making, instead of using waste disposal technique such as landfilling. Refuse samples from Dorayi/Zage and Rimin Kira refuse dumping sites Kano Municipal, Kano State Nigeria were collected. The refuse samples were sorted and all the non-biodegradables materials were removed. A compost was made from Sample N in 20 days while 9 days was required to produce a compost from sample P. Kjeldahl Nitrogen determination method and simple procedure for total carbon determination method were used to determine the percentages of nitrogen and carbon in the samples. The results have shown that, the percentages of nitrogen in the samples were found to be 1.64% for sample N and 1.71% for sample P. The percentages of carbon in the samples are 6.8% for sample N and 6.3% for sample P. The C/N ratio for sample N was 4.15:1 and that of sample P was 3.69:1.Kano municipal refuse contains a lot of organic wastes which are very difficult to incinerate. Therefore, Composting method is the best option for the disposal of the refuse rather than directly dumped in the streets.

A methodology for the ecological assessment of technologies for municipal solid waste (MSW) processing and solid recovered fuel (SRF) production is proposed, including calculations of direct, indirect and prevented greenhouse gas emissions at all stages of waste management, taking into account the composition of the waste, the properties of the individual components of the MSW and the characteristics of used equipment. The elemental balance of fossil and biogenic carbon was calculated for MSW management system. It is concluded that MSW processing with recyclables recovery and SRF production can reduce greenhouse gases release from 5.8 to 67.6 % with respect to waste disposal at the MSW landfill.

Emission Of Greenhouse Gases

The research is aimed at comparing different methods of municipal solid waste treatment (waste burial, composting, complex recycling) depending on the values of generated greenhouse gases. In order to compare waste burial and composting of municipal solid waste based on amount of generated greenhouse gases the calculation methods used for compiling the National Inventory, were taken.  The mass balance method was used to estimate the output of a product of complex recycling. The municipal solid waste components differ by amount of degradable organic carbon and decomposition rate but have the largest mass. The municipal solid waste treatment techniques consist in placing such waste at landfills and dumps which are sources of environmental pollution, for example, by greenhouse gases. There are other organic waste treatment methods, such as composting via different technologies, burning, recycling etc. But all of them are also associated with greenhouse gases emission. Easily decomposed organic waste can be used for production of organic fertilizers, but a mandatory requirement, that is separation from the general municipal solid waste stream at the time of waste production, should be complied with. A complex recycling of easily decomposed organic waste, including anaerobic and aerobic composting is offered as an efficient way of waste management. The article presents a comparative analysis of various methods of municipal solid waste treatment based on the amount of greenhouse gases emitted in the Odessa Region. It considers three waste treatment approaches: all waste mass is to be placed at landfills and dumps, composting of some of park and garden waste and burial of other components, complex recycling of food, park and garden waste and some of paper waste according to the developed scheme. Complex recycling offers the least value of total greenhouse gases emission over a five-year period whereas waste disposal is characterized by the highest value thereof.  The complex recovery of components containing bioavailable organic carbon through anaerobic fermentation method excludes emission of greenhouse gases into the atmosphere, as the biogas produced can be collected and extracted. However, over a long period, even after two-stage complex recycling, the total emission of greenhouse gases will be lower comparing to other methods of easily decomposed organic waste treatment. Emission of greenhouse gases in case of waste disposal has a prolonged nature whereas emission of greenhouse gases in case of composting occurs within a short period of time which should be taken into account when analyzing the prospects of solving the municipal solid waste problem.

At present, the global warming has drew people`s attention to the emissions of greenhouse gases such as CO2, the essence of which is worrying about the more and more carbon emissions. PP-R pipe has been widely used in production and livelihood, so evaluating the carbon footprint of PP-R pipe is very necessary. This paper evaluated the carbon footprint of PP-R pipe from the production of raw materials to waste disposal, based on the life cycle assessment. The result of the study is that, in the life cycle of PP-R pipe 74.02% of the total carbon emissions come from the production of raw materials. But if using reclaimed materials to replace the total carbon emissions would reduce 52.90%. So an innovative technology of PP-R raw materials producing and using more reclaimed materials are the keys to cut down the carbon emissions of PP-R pipe.

Global warming is a gradual increase in the average temperature of the Earth’s atmosphere caused by the increased volumes of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. Greenhouse gases is trapped inside the atmosphere and caused UV radiation difficulty passing through Earth’s atmosphere, a processed is often referred to as the greenhouse effect. Reclamation and revegetation activities were expected could decrease the greenhouse effect. The aims of the research is to estimate total carbon stock in Pine Forest age 2005 or 11 years and 2012 or 4 years, and also to compare the result with former research in post mining revegetation site PT Holcim Indonesia Tbk. Biomass measurement of trees, poles, and saplings is conducted with non-destructive methods meanwhile biomass measurements of understorey, litter, and necromassa used destructive methods. The result showed that the value of biomass and carbon stock on the 2005 pine stand is acquired 75.31 tons/ha and 35.39 tons/ha. The value of the biomass and carbon stock on the 2012 pine stand is acquired 12.72 tons/ha and 5.98 ton/ha or increased from the previous year's measurement. Increasing of biomass content and carbon stocks is caused several factors such as increasing of diameter increment dan site quality. Keywords: biomass, carbon, reclamation
