Courtesy: ISO 16559:2014 Solid Biofuels Biologically produced alcohols, most commonly ethanol, and less commonly propanol and butanol, are produced by the action of microorganisms and enzymes through the fermentation of sugars or starches (easiest), or cellulose (which is more difficult). Ethanol fuel is the most common biofuel worldwide, particularly in Brazil. Alcohol fuels are produced by fermentation of sugars derived from wheat, corn, sugar beets, sugar cane, molasses and any sugar or starch from […]

Courtesy: ISO 16559: 2014 Solid biofuels Estimates about the climate impact from biofuels vary widely based on the methodology and exact situation examined. In general, biofuels emit fewer greenhouse gas emissions when burned in an engine and are generally considered carbon-neutral fuels as the carbon emitted has been captured from the atmosphere by the crops used in production. However, life-cycle assessments of […]
Courtesy: ISO 16559:2014 Solid biofuels First-generation biofuels are fuels made from food crops grown on arable land. The crop’s sugar, starch, or oil content is converted into biodiesel or ethanol, using transesterification, or yeast fermentation. Up to 40% of corn produced in the United States is used to make ethanol, and worldwide 10% of all grain is […]
Courtesy: ISO 16559: 2014 Solid Biofuels 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. Since biomass can be used as a fuel directly (e.g. wood logs), some people use the words biomass and biofuel interchangeably. However, the word biofuel is usually reserved […]

Courtesy: ISO 16840 Wheelchair seating The development of wheelchair seating as a sub-specialty of rehabilitation services has been occurring overthe last several decades. This practice involves the selection and provision of wheelchair seating products thatprovide improved body support, movement control, and injury prevention for the wheelchair user. Inherent inthis selection process is the measurement and […]
