Advances in research of greenhouse gasses emission reduction by agricultural irrigation engineering

This investigation aims to study the value of synthesized zeolite in reducing greenhouse gasses (GHGs) emitted by rice stubble. The experiment was divided into 2 parts. Part I com-prised a study of the efficiency of GHGs reduction by synthesized zeolite and part II involved application of synthesized zeolite to reduce the cumulative GHGs emissions over 110 days from paddy rice cultivation in Khlong 4, Pathum Thani Province. The experiments comprised 2 treatments: untreated control (I), and rice stubble with addition of synthesized zeolite (II). The study measured changes in the emissions of CH4 and CO2, conducted 3 d per week for 1.30 h during the cultivation period. The result s showed that rice stubble synthesized zeolite could reduce GHGs CH4 and CO2under irrigated conditions. In the experiment, synthesized zeolite had an efficiency of 8.91% and 24.5% in reducing CH4 and CO2, respectively. Footprint analysis showed that both gases were continuously emitted throughout cultivation. In Cumulative emissions from the control treatment were 42.57 g CH4 m-2 cropand 86.40g CO2 m-2 crop. Zeolite addition reduced emission levels to 30.71 g CH4 m-2 crop and 57.77 g CO2 m-2 crop. The reduction efficiencies CH4 and CO2 were 27.87% and 33.14%, respectively. It can be concluded that the rice stubble synthesized zeolite was capable of reducing GHGs significantly and that the efficiency was rate-dependent. It was clear that the GHGs emission reduction rate of synthesized zeolite was 0.148 g CH4 m-2 g zeolite and 0.358 g CO2 m-2 g zeolite.

The palm oil industry produces greenhouse gas emissions such as carbon dioxide (CO2), methane (CH4), nitrous oxide(N2O) and other gases through the processing, transportation of vehicles and waste produced. Greenhouse gas emissions can be calculated by the Intergovernmental Panel On Climate Change (IPCC) method. The biggest emission source in the palm oil mill(POM) industry comes from Palm Oil Mill Effluent (POME) and can be reduced by capturing the methane. By making an estimation of greenhouse gases (GHGs) from the operation of the methane capture installation, the total emissions reduced that produced will be known. The palm oil mills that analyzed was a palm oil mill located in Belitung Island, Indonesia. The purpose of this study was to estimate the GHGs emission reduction from the palm oil mill after the installation of biogas methane capture facility. Using IPCC method, the total actual emissions reduction is 70,6%, and without addition of sludge removal in the reactor, the reduction is 84,7%.

This paper investigates costs and benefits associated with low-carbon economic development pathways realization to the mid XXI century. 30 scenarios covering practically all “visions of the future” were developed by several research groups based on scenario assumptions agreed upon in advance. It is shown that with a very high probability Russian energy-related GHG emissions will reach the peak before 2050, which will be at least 11% below the 1990 emission level. The height of the peak depends on portfolio of GHG emissions mitigation measures. Efforts to keep 2050 GHG emissions 25-30% below the 1990 level bring no GDP losses. GDP impact of deep GHG emission reduction - by 50% of the 1990 level - varies from plus 4% to minus 9%. Finally, very deep GHG emission reduction - by 80% - may bring GDP losses of over 10%.
