3.1 Biogenesis of methane In anaerobic digestion there are four stages: hydrolysis, acidification, acetogenesis and methane production (Sagagi et al; 2009; Rai 2004). Different microorganisms play a significant role in each stage ofthe processes. Therefore, intervention and follow up in all the stages is essential for enhanced and optimum methane production. 3.1.1 Enzymatic hydrolysis Enzymatic hydrolysis is the process where the fats, starches and proteins…

energy sources today struggle to control their CO2 emissions, as these can cause harm to the ozone layer and increase the effects of greenhouse gases, potentially warming the planet. Biomass, for the most part, creates no harmful CO2 emissions. Biogas Biogas is a gaseous mixture that is about two-thirds…

cows and other ruminants can be strong and extremely unpleasant, however cow waste is a great source of energy that can be used to power the farm. The purpose of this science fair project is to discover what kinds of biomass are best for producing biogas. The kinds of biomass you will investigate are cow manure by itself and cow manure with vegetable peelings or with mashed banana. You will figure out how…

Garbage disposals should aim to have separations between organic/raw and inorganic waste. The organic waste can be utilized in biogas digesters, along with “industrial, domestic or commercial organic waste and agricultural waste materials and energy crops”. By the process of fermentation in these waste materials, the cleaner form of energy biogas is produced, which can be used for cooking purposes and as a fuel for vehicles that use natural gas. Another step to sustainability is converting…

The value of the invasive Water hyacinth classifies as both detrimental and beneficial. The authors of The Jepson Manual, Vascular Plants of California describe the invasive plant as “Perhaps the world’s most troublesome aquatic weed.” The despised notions come from the fact that the aquatic weed increases its capacity to spread in water; peculiarly when the plant distances from its natural enemies in South America. The Water hyacinth growth appears as an island in freshwater bodies, or as a mat…

Red beet (Beta vulagaris L.) is a crop of the Chenopodiaceae family [1]. The crop is primarily cultivated for its edible roots and valued extremely for its color [1, 2]. Over the past 20 years, the production of red beets in the United States is estimated around 200,000 tonnes/ year [3, 4], of which almost 95% of the cultivated red beets are canned and only 5% are consumed as a vegetable [3]. Interestingly, this root vegetable is a crop of commercial importance [5], that is also exploited for…

Women are more vulnerable to climate changes because they are lack of access to social and financial support and education as well. There are many projects which are constituted by NGOs help to reduce vulnerability…
