با استفاده از نرم افزار GGIS که توسط IPCC (هیات بین الدول تغییر آب و هوا) ارایه گردیده، میزان نشر گازهای گلخانه ای NMVOC، N2O، CH4، CO، CO2) و ...) در بخش خانگی- تجاری، کشاورزی و حمل و نقل از سال 1373 تا 1378 در کشور براساس سوخت فسیل مصرفی محاسبه گردید. پس از آن، روند تغییر انتشار GHGs در بخش های فوق مورد بررسی قرار گرفت. در برخی موارد، کاهش نشر این گازها مبین تاثیرگذاری سیاست های بهینه سازی مص...
Abstract. Global energy consumption has eventually increased as a result of the growing world population. Various problems arise result. The accumulation greenhouse gases (GHGs), which led to shift in world's climate, is most problematic. Combined dry and steam reforming methane (CDRSM) highly advantageous method since it uses two significant GHGs, CH4 CO2, produce syngas, an intermediate produ...
Agricultural lands, because of their large area and exhaustive management practices, have a substantial impact on the earth’s carbon nitrogen cycles, agricultural activities consequence in discharges greenhouse gases (GHGs). Globally, (GHGs) emissions especially dioxide (CO 2 ), methane (CH 4 ) nitrous oxide (N O) from sector are increasing due to anthropogenic activities. Although, application...
Abstract. Climate archives reveal alternating arid and humid conditions in North Africa during the last several million years. Most likely dry phases resembled current hyper-arid landscapes, whereas wet known as African periods (AHPs) sustained much more surface water greater vegetated areas that “greened” large parts of Sahara region. Previous analyses sediment cores from Mediterranean Sea sho...
Abstract Biological wastewater treatment is linked to direct and indirect greenhouse gases (GHGs) emissions, thus new approaches on design operation of plants (WWTPs) must be adopted aiming towards GHGs emissions’ mitigation. This study evaluates the impact solids retention time (SRT) (CO 2 N O) emissions activated sludge (AS) processes with nutrients removal operating at 10, 30 180 days SRT. T...
Stabilization of atmospheric concentrations of greenhouse gases (GHGs) is a declared objective of Article 2 of the United Nations Convention on Climate Change (UNFCCC, 1992). Carbon dioxide (CO2) is the most important of these gases followed by methane (CH4) and nitrous oxide (N2O). Current atmospheric concentrations of CO2 are about 380 ppmv (parts per million volume) CO2 only and are somewher...
Livestock has been the mainstay of Indian agriculture sector and also a major source of GHGs emissions from the world’s largest livestock population. The milching livestock (including lactating dairy cattle, buffalo and goat) constitutes 21.3% of the country’s livestock. We present a detailed inventory of GHGs emissions from milching livestock (using the recent census and country-specific emiss...
The accumulation of solid organic waste is reaching critical levels in almost all regions the world. It must be managed sustainably to avoid depletion natural resources, minimize risks human health, reduce environmental burdens, and maintain an overall balance ecosystem. This research focuses on anaerobic digestion bovine swine excreta with without applying beneficial microorganisms as a viable...
