Hempcrete. Construction block made from hempcrete However, the typical compressive strength is around 1 MPa,[4] around 1/20 that of residential grade concrete. Hempcrete walls must be used together with a frame of another material that supports the vertical load in building construction, as hempcrete's density is 15% that of traditional concrete.[5] Like other plant products, the hemp crop absorbs carbon dioxide gas as it grows, retaining the carbon and releasing the oxygen. 165 kg of carbon can be theoretically absorbed and locked up by 1 m3 of hempcrete wall over many decades.[6] References[edit] Jump up ^ Allin, Steve.

Vegetable oil is an alternative fuel for Diesel engines and for heating oil burners. For engines designed to burn diesel fuel, the viscosity of vegetable oil must be lowered to allow for proper atomization of the fuel, otherwise incomplete combustion and carbon build up will ultimately damage the engine.
History[edit] Rudolf Diesel Rudolf Diesel was the father of the engine which bears his name. Periodic petroleum shortages spurred research into vegetable oil as a diesel substitute during the 1930s and 1940s, and again in the 1970s and early 1980s when straight vegetable oil enjoyed its highest level of scientific interest. Academic research into straight vegetable oil fell off sharply in the 1980s with falling petroleum prices and greater interest in biodiesel as an option that did not require extensive vehicle modification. Application and usability[edit] Modified fuel systems[edit] Unmodified indirect injection engines[edit] Home heating[edit] Biofuel. A biofuel is a fuel that contains energy from geologically recent carbon fixation.
These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion (biomass refers to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form.
This new biomass can be used for biofuels. Biofuels have increased in popularity because of rising oil prices and the need for energy security. Bioethanol is an alcohol made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as corn, sugarcane, or sweet sorghum. Liquid fuels for transportation[edit] First-generation biofuels[edit] Ethanol[edit] Biodiesel[edit] Other bioalcohols[edit] Papermaking. Paper-making is the process of making paper, a substance which is used universally today for writing and packaging.
In paper-making, a dilute suspension of fibres in water is drained through a screen, so that a mat of randomly interwoven fibres is laid down. Water is removed from this mat of fibres by pressing and drying to make paper. Since the invention of the Fourdrinier machine in the 19th century, most paper has been made from wood pulp because of cost. But other fibre sources such as cotton and textiles are used for high-quality papers. History[edit] Hemp wrapping paper, China, circa 100 BCE. In the 8th century, paper spread to the Islamic world, where the rudimentary and laborious process of paper-making was refined and machinery was designed for bulk manufacturing of paper. Modern paper-making began in the early 19th century in Europe with the development of Fourdrinier machine, which produces a continuous roll of paper rather than individual sheets.

The words fabric and cloth are used in textile assembly trades (such as tailoring and dressmaking) as synonyms for textile. However, there are subtle differences in these terms in specialized usage. Etymology[edit] The word 'textile' is from Latin, from the adjective textilis, meaning 'woven', from textus, the past participle of the verb texere, 'to weave'.[4] The word 'fabric' also derives from Latin, most recently from the Middle French fabrique, or 'building, thing made', and earlier as the Latin fabrica 'workshop; an art, trade; a skillful production, structure, fabric', which is from the Latin faber, or 'artisan who works in hard materials', from PIE dhabh-, meaning 'to fit together'.[5] History[edit] During the 15th century, textiles were the largest single industry.
Uses[edit] Definitions and Descriptions of Fabric and Cloth. Fabric and Cloth This is a rather odd category, listing 269 names of kinds of fabric and cloth. There is an enormous variety in fabrics, with many different national, historical and regional varieties. It is interesting to note, however, that almost all of the types of fabric listed below are variants or blends of just five basic fabric types (silk, cotton, linen, wool and worsted). Many of the terms are foreign in origin; English orthography has been adopted where it exists. PLEASE NOTE: I am not a fabric dealer. I do not know where to find weird fabrics, nor am I qualified to comment on the qualities or uses of any type of fabric, except from the definitions listed in the dictionaries from which this list was compiled.

List of fabric names From Wikipedia, the free encyclopedia Jump to: navigation, search For the definition of 'textiles', see textile. Fabric names in this list include fabrics that are woven, non-woven, as well as knitted fabrics and netting fabrics, and technical fabrics (such as Gore-Tex and Gannex). A fabric may share the name of the fibre from which it is made if its content is derived entirely from the fibre (such as angora fabric made of 100% angora fibre).

Hemp. Other variants of the herb Cannabis sativa are widely used as a drug, commonly known as marijuana. These variants are typically low growing and have higher content of tetrahydrocannabinol (THC). The legality of Cannabis varies widely from country to country, and from state to state in the United States. In many countries regulatory limits for concentrations of psychoactive drug compounds, particularly THC, in hemp require the use of strains of the plant which are bred for low content.[1] Uses[edit] Hemp grown for milk animal fodder In modern times hemp is used for industrial purposes including paper, textiles, clothing, biodegradable plastics, construction (as with Hempcrete and insulation), body products, health food and bio-fuel. Food[edit] Hemp seeds Hemp seeds can be eaten raw, ground into a meal, sprouted, made into hemp milk (akin to soy milk), prepared as tea,[5] and used in baking.
