Food vs fuel is the debate regarding the risk of diverting farmland or crops for biofuels production in detriment of the food supply on a global scale. Essentially the debate refers to the possibility that by farmers increasing their production of these crops, often through government subsidy incentives, their time and land is shifted away from other types of non-biofuel crops driving up the ...
A bio-ethanol fireplace with artificial wood logs. An ethanol fireplace (also bio-ethanol fireplace, bio fireplace), is a type of fireplace which burns ethanol fuel. They are often installed without a chimney. Ethanol for these fires is often marketed as bioethanol (ethanol produced from biomass). [clarification needed]
Low-VOC paint types include latex (water-based), recycled latex (water-based), acrylic, and milk paint. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC. [citation ...
The two most common types of biofuel are bioethanol and biodiesel. Brazil 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. [17]
The cost of processing the feedstock into bioethanol; Such a calculation may or may not consider the following effects: The cost of the change in land use of the area where the fuel feedstock is grown. The cost of transportation of the bioethanol from the factory to its point of use; The efficiency of the bioethanol compared with standard gasoline
A dish of ethanol aflame. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]
These compounds can serve as raw materials for biofuels like bioethanol or biodiesel. [51] Therefore, even though combusting microalgae-based fuel for energy would still produce emissions like any other fuel, it could be close to carbon-neutral if they, as a whole, consumed as much carbon dioxide as is emitted during combustion.
