  2. Biodiesel production - Wikipedia

    en.wikipedia.org/wiki/Biodiesel_production

    Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products .

  3. Cellular manufacturing - Wikipedia

    en.wikipedia.org/wiki/Cellular_manufacturing

    The goal of cellular manufacturing is to move as quickly as possible, make a wide variety of similar products, while making as little waste as possible. Cellular manufacturing involves the use of multiple "cells" in an assembly line fashion. Each of these cells is composed of one or multiple different machines which accomplish a certain task.

  5. Biodiesel - Wikipedia

    en.wikipedia.org/wiki/Biodiesel

    Biodiesel production has evolved significantly, with early methods including the direct use of vegetable oils, to more advanced processes like transesterification, which reduces viscosity and improves combustion properties. Notably, biodiesel production generates glycerol as a by-product, which has its own commercial applications.

  6. Shelf life - Wikipedia

    en.wikipedia.org/wiki/Shelf_life

    Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.

    en.wikipedia.org/wiki/Alternative_fuel

    In China, alternative fuel vehicles should comply with technical guidelines for the local production of alternative-fuel vehicles: they should have a shelf life of more than 100,000 kilometres (62,000 mi), and a complete charge should take less than seven hours. Up to 80% of a charge must be available after less than 30 minutes of charging.

  9. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass , which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [ 1 ]
