Sustainability
Specific definitions of sustainability are difficult to agree on and have varied in the literature and over time. The concept of sustainability can be used to guide decisions at the global, national, and individual levels (e.g. sustainable living). Sustainability is commonly described as having three dimensions (also called pillars): environmental, economic, and social. Many publications state that the environmental dimension (also called "planetary integrity" or "ecological integrity") is the most important, and, in everyday usage, "sustainability" is often focused on countering major environmental problems, such as climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution. Humanity is now exceeding several "planetary boundaries". A closely related concept is that of sustainable development, and the terms are often used synonymously. However, UNESCO distinguishes the two thus: "''Sustainability'' is often thought of as a lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biobutanol
220px, Butanol, a C-4 hydrocarbon is a promising bio-derived fuel, which shares many properties with gasoline. Butanol may be used as a fuel in an internal combustion engine. It is more similar to gasoline than it is to ethanol. A C4-hydrocarbon, butanol is a drop-in fuel and thus works in vehicles designed for use with gasoline without modification. Both ''n''-butanol and isobutanol have been studied as possible fuels. Both can be produced from biomass (as "biobutanol" ) as well as from fossil fuels (as "petrobutanol"). The chemical properties depend on the isomer (''n''-butanol or isobutanol), not on the production method. Although intriguing in many ways, butanol fuel is rarely economically competitive. Genetically modified organisms Obtaining higher yields of butanol involves manipulation of the metabolic networks using metabolic engineering and genetic engineering. While significant progress has been made fermentation pathways for producing butanol remain inefficient. Tite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Economy
A low-carbon economy (LCE) or decarbonised economy is an economy based on energy sources that produce low levels of greenhouse gas (GHG) emissions. GHG emissions due to human activity are the dominant cause of observed climate change since the mid-20th century. Continued emission of greenhouse gases will cause long-lasting changes around the world, increasing the likelihood of severe, pervasive, and irreversible effects for people and ecosystems. Shifting to a low-carbon economy on a global scale could bring substantial benefits both for developed and developing countries. Many countries around the world are designing and implementing low-emission development strategies (LEDS). These strategies seek to achieve social, economic, and environmental development goals while reducing long-term greenhouse gas emissions and increasing resilience to the effects of climate change. Globally implemented low-carbon economies are therefore proposed as a precursor to the more advanced, zero-ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Accounting
Greenhouse gas accounting or Carbon accounting is a framework of methods to measure and track how much greenhouse gas (GHG) an organization emits or takes actions to reduce. Corporations, cities and other groups use these techniques to help limit climate change. After a baseline of emissions is established, an organization can then set targets for reducing emissions and track progress towards those targets. Many companies and governments are required to report their GHG emissions as part of their social responsibility efforts, or to meet legal requirements. GHG accounting enables them to calculate and report GHG emissions in a consistent and transparent manner. GHG accounting also helps in valuing emission reduction efforts such as carbon offset projects. These cover areas such as forestry or renewable energy. The accounting methods are used to quantify the expected GHG reductions of these projects. These techniques can also help understand the environmental impact of specific ...

Blue Bag
A blue bag is a blue coloured, sometimes semi-transparent bag for waste, mandated for use in some localities for refuse or for certain specific types of refuse. Description A blue bag is a blue coloured, sometimes semi-transparent bag for waste. In some localities, they are mandated for use for refuse or for certain specific types of refuse. In the latter usage, the distinguishing color serves to assist in recycling programs; blue typically indicates that the bag contains glass, plastic, or polyethylene content. Location-specific Taiwan In Taipei, residents must use an official blue garbage bag to dispose of general waste, with the bags being collected from designated pickup spots. United States Chicago The City of Chicago implemented a blue bag system in 1995. It operates by requiring willing participants to purchase blue garbage bags (available at major grocery stores throughout the city) and depositing recyclable material in the bags. The waste may be paper-based (cardboar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeochemistry
Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment (including the biosphere, the cryosphere, the hydrosphere, the pedosphere, the atmosphere, and the lithosphere). In particular, biogeochemistry is the study of biogeochemical cycles, the cycles of chemical elements such as carbon and nitrogen, and their interactions with and incorporation into living things transported through earth scale biological systems in space and time. The field focuses on chemical cycles which are either driven by or influence biological activity. Particular emphasis is placed on the study of carbon, nitrogen, sulfur, iron, and phosphorus cycles. Biogeochemistry is a systems science closely related to systems ecology. History Early History Early Greeks established some of the core ideas of biogeochemistry, such as nature consisting of cycles. 17th ...

Biogas Powerplant
Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion. Anaerobic digestion occurs naturally in some soils and in lake and oceanic basin sediments, where it is usually referred to as "anaerobic activity". This is the source of marsh gas methane as discovered by Alessandro Volta in 1776. The digestion process begins with bacterial hydrolysis of the input materials. Insoluble organic polymers, such as carbohydrates, are broken down to soluble derivatives that become available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide, hydrogen, ammonia, and organic acids. In acetogenesis, bacteria convert these resulting organic acids into ...

Biogas
Biogas is a mixture of gases, primarily consisting of methane, carbon dioxide and hydrogen sulphide, produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste and food waste. It is a renewable energy source. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogen inside an anaerobic digester, biodigester or a bioreactor. Biogas is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), moisture and siloxanes. The gases methane, hydrogen, and carbon monoxide () can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. Biogas can be compressed after removal of carbon dioxide and hydrogen sulphide, the same way as natural gas is compressed to CN ...

Biofuelwatch
Biofuelwatch is a non-governmental environmental organization based in the United Kingdom and the United States, which works to raise awareness of the negative impacts of industrial biofuels and bioenergy, on biodiversity, human rights, food sovereignty and climate change, human rights abuses, the impoverishment and dispossession of local populations, water and soil degradation, loss of food sovereignty and loss of food security. It opposes the expansion of industrial monocultures driven by demand for bioenergy, and instead advocates for food sovereignty, agroecological farming practices, ecosystem and biodiversity protection and human rights. In the UK,it has active campaigns against bioliquid and biomass power stations and the subsidies (Renewable Obligation Certificates) available for those. In the US, Biofuelwatch works closely with network of groups and campaigners against industrial biomass developments and policies. Internationally, the organisation works with a variety ...

Biofuel
Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels, such as oil. According to the United States Energy Information Administration (EIA), biofuels are mostly used for transportation, but can also be used for heating and electricity. Biofuel can be produced from plants or from agricultural, domestic or industrial biowaste. The greenhouse gas mitigation potential of biofuel varies considerably, from emission levels comparable to fossil fuels in some scenarios to negative emissions in others. See the biomass article for more on this particular subject. The two most common types of biofuel are bioethanol and biodiesel. The U.S. is the largest producer of bioethanol, while the EU is the largest producer of biodiesel. The energy content in the global production of bioethanol and biodiesel is 2.2 and 1.8 EJ per year, respectively. * Bioethanol is an alcohol made by fermen ...

Biofuel In The United States
The United States produces mainly biodiesel and ethanol fuel, which uses corn as the main feedstock. The US is the world's largest producer of ethanol, having produced nearly 16 billion gallons in 2017 alone. The United States, together with Brazil accounted for 85 percent of all ethanol production, with total world production of 27.05 billion gallons. Biodiesel is commercially available in most oilseed-producing states. , it was somewhat more expensive than fossil diesel, though it is still commonly produced in relatively small quantities (in comparison to petroleum products and ethanol fuel). Biofuels are mainly used mixed with fossil fuels. They are also used as additives. The largest biodiesel consumer is the U.S. Army. Most light vehicles on the road today in the US can run on blends of up to 10% ethanol, and motor vehicle manufacturers already produce vehicles designed to run on much higher ethanol blends. The demand for bioethanol fuel in the United States was stimulated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biofuel In Brazil
The use of biofuels varies by region. The world leaders in biofuel development and use are Brazil, United States, France, Sweden and Germany. Americas Brazil The government of Brazil hopes to build on the success of the Proálcool ethanol program by expanding the production of biodiesel which must contain 2% biodiesel by 2008, and 5% by 2013. Canada The government of Canada aims for 45% of the country's gasoline consumption to contain 10% ethanol by 2010. Colombia and Venezuela Colombia mandates the use of 10% ethanol in all gasoline sold in cities with populations exceeding 500,000. In Venezuela, the state oil company is supporting the construction of 15 sugar cane distilleries over the next five years, as the government introduces an E10 (10% ethanol) blending mandate. United States The Energy Policy Act of 2005 was passed by the United States Congress on July 29, 2005, and signed into law by President George W. Bush on August 8, 2005, at Sandia National Laboratorie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
