2. Methodology 2.1 Goal definition The goal of this study is to assess and compare the environmental impacts of three management alternatives for the end-of-life of natural cork stoppers using LCA methodology. Several scenarios were considered within each alternative. The alternatives and associated scenarios under study are as follows: A. Incineration, including: • Scenario 1: incineration with electricity generation. • Scenario 2: incineration with combined heat and power generation (CHP). B…

perennial warm season grass with the ability to produce moderate to high biomass yields on marginal lands. These characters have resulted in the use of switchgrass in several Bioenergy conversion processes, including cellulosic ethanol production, biogas, and direct combustion for thermal energy applications.” (Carter, Jimmy 1) Switchgrass produces cellulose, when cellulose is broken down and ferment it, then becomes cellulosic ethanol which can be used to fuel automobiles. In this research…

10754BPhotoelectric separation technology is a method to separate different materials according to the characteristic of the light reflection of material surface and has been used to separate glass of different colours. The colorless glass and colored glass contained in the waste glass should be separated according to various colors. Electric separation is a method using different electrical properties of components in high voltage electric field to separate wastes. This technology is mainly…

About 38 percent of the world total lands are using by human for agriculture. It seems like not a problem today. As a prediction, the human population will increase up to 8.6 billion for the next 50 years (Despommier, 2014). For this reason, we will need more lands and more nature resources to fulfill our demand of foods. As a prediction, people will need an additional 109 hectares of land for feed all the people (Despommier, 2014). As the population increase, human requires more and more land.…

The Ghost Map by Steven Johnson is a true story of a terrifying outbreak of cholera and how Dr. John Snow and reverend Henry Whitehead used their knowledge of the disease to find out how prevalent it was over the whole city of London. The disease may have been unfamiliar to them, but common to the millions of people around the country, whose living conditions and sanitation processes were not as good or advanced as theirs. The story reflects the world through the wide varieties of disciplines,…

2.1 Jatropha Curcas Jatropha curcas have a various advantages than by making it as a biodiesel feedstock. Jatropha Curcas can also help to recover the problematic lands such as soil erosion and act as hedge (Openshaw, 2000). The primary conservation benefits like improved soil restoration and management can be achieved by cultivation of Jatropha curcas. Other than that, this plant is act as fence which is to protect the agriculture…

made and outlines plans for continuing to conserve water (Fat Tire). Water conservations is not the only way they work with water used by their plants. At least one site has a water treatment plant that treats water but also produces methane gas. The biogas produced is then piped back into the plant to power heat and power engines (Fat Tire). Water is not the only resource that they try to conserve and reduce, this thought process also applies to their waste. Focusing on the waste produced and…

Introducing Genes from other Organisms to Improve Efficiency Besides using just genes from the plant itself, scientists have been able to introduce other genes from other organisms into the plant cells, one of the first being (Fructose-1, 6-Sedoheptulose-1, 7-biphosphate). The (Fructose-1, 6-Sedoheptulose-1, 7-biphosphate) gene comes from cyanobacteria and was introduced to a transgenic tobacco plant. Once again, through the use of overexpression, the tobacco plant showed an increased…

The oldest energy source used on Earth ever since our most further-in-time ancestor, the cavemen. The first thing that comes in to mind with biomass is with plants and most people will think that getting energy from plants is burning. Burning is not the only way of extracting energy from these plants. There are not only the method of burning but also others such as the decomposition by bacteria, fermentation and conversion. Fresh plants are used to obtain that energy, but also dead plants,…
