In the era of globalization and international trade, the production-based CO2 emissions accounting system, proposed by United Nations Framework Convention on Climate Change, can easily lead to a “carbon leakage” issue. Thus, the accounting of consumption-based carbon emissions and carbon emissions embodied in international trade has received considerable research attention. Nevertheless, resear...

Pyrolitic conversion of lignocellulosic biomass, such as switchgrass and other agricultural residues, to bio-fuels is being considered for national energy security and for environmental advantages. Bio-oil, syngas and bio-char were produced and characterized from switchgrass at 400, 500 and 600 0C by pyrolysis. Bio-oil yield increased from 22 to 37%, syn-gas yield increased from 8 to 26%, and b...

evaluation of carbon sequestration ability by chlorella vulgaris in water with different salinity expanded abstractintroductionnowadays, cultivation of microalgae in order to reduce co2 has gained attention all around the world. one of the outstanding features is that photosynthetic efficiency of microalgae is greater than that of terrestrial plants. carbon dioxide (co2) has been known as one o...

The aim of the research was to develop a laboratory test stand for forming vegeburgers and determine carbon footprint vegeburger production technology with addition frozen vegetable outgrades. This material is waste from food production. During research, unique recipes fabricated outgrades, potatoes, fiber, potato flour, salt spices were also developed. physicochemical properties, texture color...

Methane production from Welsh ponies fed 2 isoenergetic diets (NE basis) at maintenance was studied in a crossover design with 4 mature geldings (230 ± 10.5 kg BW, mean ± SE). Treatments included a roughage-only (R) diet (5.1 kg DM/d) or a roughage plus cereal mix (RC) diet (2.5 kg DM hay/d plus 1.1 kg DM cereal mix/d). For both diets, the same grass hay was used (898 g DM/kg and 4.5 MJ NE/kg D...

BACKGROUND Production of fuels from the abundant and wasteful CO2 is a promising approach to reduce carbon emission and consumption of fossil fuels. Autotrophic microbes naturally assimilate CO2 using energy from light, hydrogen, and/or sulfur. However, their slow growth rates call for investigation of the possibility of heterotrophic CO2 fixation. Although preliminary research has suggested th...

In conventional greenhouse systems, recent innovations have contributed to increased production levels, and at the same time, to the decreased ecological footprint in terms of the reduction of water use, nutrients and CO2 emissions. Several examples of application of standard and innovative technologies to improve production, optimize utilization of solar energy and increase efficiency of energ...

BACKGROUND Potent inhaled anesthetics degrade in the presence of the strong bases (sodium hydroxide or potassium hydroxide) in carbon dioxide (CO2) absorbents. A new absorbent, Amsorb (Armstrong Medical Ltd., Coleraine, Northern Ireland), does not employ these strong bases. This study compared the scavenging efficacy and compound A production of two commercially available absorbents (soda lime ...
